▼ Frost can affect the productivity and distribution of plants, as it can cause plant cell rupture and xylem cavitation, which may limit the water transport, growth, and survival of plants. Climate change is expected to increase the effect of frost on plants, making them more susceptible to frost events. Therefore it is necessary to determine the frost susceptibility of species, which may be done using a plant functional trait approach. Plant functional traits are any attribute of a plant which can influence its establishment, survival and fitness. Frost tolerant species are expected to possess traits that reflect a conservative life history strategy aimed at stress tolerance, such as small and thick leaves, low specific leaf area, high leaf dry matter content, high leaf vein density and vein length per unit area, and high wood density. We sampled twenty-three plant species in Australia and twenty-five plant species in New Zealand, and compared their functional traits to existing species-specific frost susceptibility datasets. The traits most likely to influence frost susceptibility appear to be leaf size traits, leaf venation traits, and wood density, which is most likely due to the important effects these traits have on plant hydraulics, which is known to be significantly impacted by frost. Higher leaf vein density and vein length per unit area provide greater leaf hydraulics and better water use efficiency, which helps plants survive the water stress conditions that can be caused by frost. Higher wood density is related to having narrow xylem vessels, which are more resistant to freeze-thaw induced xylem cavitation and embolism, compared to wider xylem vessels. This study has provided globally-new information about which plant functional traits may be associated with frost susceptibility in plant species, and demonstrates for the first time the promise of leaf venation traits as a means of predicting and understanding response of plants to frost.

▼ Across plant taxa there are large-scale correlations among ecophysiological
leaf traits:
Specific leaf area (SLA), maximum photosynthetic rate (Amax),
Leaf nitrogen content (NL), and
leaf lifespan (LL). Suite syndromes of
leaf traits are associated among r and K-selected species and Arabidopsis thaliana ecotypes exhibit groth syndromes similar to the r and K-selection theory and range from a wide variety of latitudes of origin. The purpose of this study was to determine if the ecoyphysiological
leaf traits: SLA, Amax, Nl, LL and other growth-rleated traits were correlated across A. thaliana ecotypes from a wide range of latitudes of origin. Fifteen A. thaliana ecotypes were grown in an experimental growth chamber to determine if these ecophysiological and other growth-related
leaf traits such as
leaf initiation rate and bolting time were correlated across the ecytpes. Results indicate that SLA, Amax and NL were correlated across the ecotypes as consistent with global trends while LL was not significantly correlated. The life history trait, bolting time, was correlated with
leaf tratis. There was a wide range of
leaf age and change in longevity among the leaves, making
leaf lifespan difficult to determine. The results from this study indicate that A. thaliana will be a good model in order to understand the developmental and genetic links with these correlations.

▼ High latitude regions are warming faster than most regions. Studies documenting change in plant cover due to warming have reported that graminoids, deciduous shrubs, and evergreen shrubs are increasing in some regions of the Arctic, but not at others. Mixed responses to warming have caused researchers to shift towards an emphasis on functional traits of individual species rather than their growth forms. This thesis focuses on ten measured plant functional traits for twelve arctic species at three regions spanning a latitudinal gradient in northern Alaska (Utqiaġvik, Atqasuk, and Toolik Lake). We compare mean trait values across the three regions for each species and find considerable variability within a growth form. Quantification of intraspecific variation (ITV) in the three populations showed high amounts of variation for some traits (>50% for normalized difference vegetation index (NDVI) and photosynthetic capacity (Amax)) but not for other traits (<15% for plant height, leaf area, specific leaf area (SLA), leaf thickness, and leaf dry matter content (LDMC)). Amount of ITV also varied across regions. To better understand why trends in plant cover and functional traits vary across regions, change in cover (measured three times from 2008 to 2018) was also compared with observed trait values (measured in 2018) for twelve dominant species. Canonical correspondence analysis (CCA) suggested a relationship between change in species cover and functional traits. Species increasing in cover were associated with photosynthetic capacity (Amax) and species decreasing in cover were associated with LDMC. Investigation of community-weighted trait means (CWM) showed that whole community rather than species-specific trait values may be more indicative of future change. CWM changed significantly over time for all traits at Utqiaġvik and Atqasuk, but not Toolik Lake. Non-significant results in direct cover-trait relationships also suggest that multiple traits rather than a single trait may be responsible for shifts in plant cover, supporting a multidimensional approach to future trait-based studies. Additionally, studies investigating the impact of warming on vegetation that incorporate ITV will be able to provide more accurate predictions for future change.

▼ Grasslands are among the largest ecosystems in the world and provide numerous ecosystem services. These services include the ecosystem benefits important in an agricultural context such as biomass production and benefits from an ecological perspective such as mitigation of greenhouse gas emissions. My research has investigated the physiology, productivity and community dynamics of grassland ecosystems by combining field studies and modeling techniques. In an agriculture context, primary productivity is especially important. Therefore, the first part of my research addresses the optimal harvesting time of prairie biomass to achieve the maximum yield within one production cycle. Due to the biomass quantity-quality trade-off, the balance among yield, biomass quality, and impacts on environment needs to be carefully considered when harvesting prairie mixtures. Allowing grasses to completely senesce and recycle nutrients can reduce fertilizer requirements and improve feedstock quality by reducing biomass moisture and mineral content. But the trade-off is that a late harvest always results in less harvestable biomass. Effects of harvest time on biomass nitrogen concentration, moisture and yield of prairie production systems are rarely investigated. Therefore, I investigated responses of these factors to harvest time in prairie mixtures by conducting experiments in a restored tallgrass prairie in Urbana, IL. The results suggest that the optimal harvest time that maximizes expected net returns and balances feedstock quality and quantity is between November and January.
Next, relationships between
leaf traits and photosynthetic rates are commonly used to predict primary productivity at scales from the
leaf to the globe. Hence, the second part of my dissertation focuses on investigating the variation in these relationships across taxonomic scales using a Bayesian parameterization of
leaf photosynthesis models. Photosynthetic CO2 and light response curves and
leaf ecophysiological traits of 25 grassland species were measured. The effects of
leaf traits on photosynthetic capacity were quantified at different taxonomic scales through
leaf photosynthesis model parameterization. I found that the effects of plant physiological traits on photosynthetic capacity and parameters varied among species and plant functional types. These results suggest that one broad-scale relationship is not sufficient to characterize ecosystem conditions and changes at multiple scales.
The third part of my research builds on this foundation of
leaf ecophysiology and aims to integrate the interaction between physiology, community and ecosystem functioning into a unified picture by testing the effects of photosynthesis on community dynamics. To test the relationship between photosynthesis and community composition, I measured species-level photosynthetic rate and abundance in a tallgrass prairie monthly across two growing seasons. Large portions of within-species and across-species variation in percent cover could be explained by seasonal changes in…

▼ Foliar concentration of nutrients is an important indicator of the state of mineral nutrition of woody species, especially as related to soil fertility and adaptations in native plant communities. The cerrado biome presents great biodiversity and heterogeneity of species even within homogenous physiognomies like the cerrado sensu stricto. This diversity can be reflected in native species growing under uniform edaphic conditions belonging to different functional groups, specially in terms of
leaf traits and phenology patterns. Woody species of the cerrado can be classified into three phenological groups, evergreens, deciduous and brevideciduous, based on the interval during which the trees remain without leaves. Annual
leaf shedding would affect the
leaf nutrient status and consequently
leaf functions such as photosynthesis and water use, and ecosystem processes such as nutrient cycling. Previous investigations on mineral nutrition of native plants of the cerrado biome reported in the literature are generally focused on comparisons of physiognomies, the influence of edaphic factors, and
specific aspects such as aluminum accumulation. The main objective of the present study was to compare the variations in
leaf nutrient concentrations among 15 woody species of a cerrado sensu stricto belonging to the three phonological groups growing on a dystrophic latosol to determine the influence of deciduousness on mineral nutrition. The main hypothesis was that evergreen species would present lower foliar concentrations of nutrients, less
specific leaf area, and smaller seasonal variations than deciduous species, because their leaves would persist beyond one annual cycle of dry and wet season. The study was conducted in a cerrado sensu stricto at the Ecological Reserve of the Instituto Brasileiro de Geografia e Estatística near Brasília in the Federal District of Brazil. Fully expanded leaves were collected from three individuals of each species at two-month intervals during one year, beginning August 2005 and analyzed for N, P, K, Ca, Mg, Fe, Mn, Zn e Cu.
Specific leaf area was determined twice toward the end of the rainy season of 2006. Soil samples from different depths up to 30 cm were collected in December 2005 and June 2006 and analyzed to determine nutrient availability. Soil analysis showed that the soil was acid and dystrophic with low availability of essential nutrients. The mean concentrations of the major nutrients, N, P, K, Ca and Mg were lower in the evergreen species than in the deciduous species. Seasonal variations were less in evergreen species. Deciduous species showed higher concentrations of N, P and K at the beginning of the rainy season when leaves were recently formed and their concentrations decreased toward the end of the rainy season and the beginning of the ix next dry season. Concentrations of Ca increased toward the end of the rainy season, as the
leaf age increased. Brevideciduous species had lower concentrations of N and P than those which shed leaves for a longer period though they had higher…

▼ As florestas ribeirinhas se dividem em matas ciliares e matas de galeria. As matas de galeria são importantes na manutenção dos recursos hídricos e da fauna a elas associada. Esses ambientes sofrem degradação e para a conservação e restauração são necessários estudos que entendam o funcionamento das espécies na comunidade. Os objetivos desse trabalho foram avaliar a variabilidade na área foliar específica em mata de galeria inundável do córrego do Glória (Uberlândia/MG) e mata de galeria não-inundável do ribeirão do Panga (Uberlândia/MG) e utilizar atributos reprodutivos como síndrome de polinização, síndrome de dispersão e sistema sexual, para comparação entre distintas áreas de mata de galeria inundável e também comparando com a mata de galeria não-inundável do Panga. Foram utilizados os dados florísticos já realizados nas matas de galeria não inundável do Panga (Uberlândia/MG), da mata de galeria inundável do Glória (Uberlândia/MG) e diversas outras matas de galeria inundável. A partir desses estudos foram calculados o IVC (Índice de Valor de Cobertura) e selecionadas as espécies. Para avaliar a variabilidade da área foliar específica foram utilizadas e as médias de AFE (área foliar específica) das espécies para comparação entre as duas áreas com o teste t de Student; já para analisar os padrões reprodutivos entre as matas de galeria inundável e compará-las com os padrões do Panga foram feitos testes de qui-quadrado. Os resultados do teste t mostraram que as médias das espécies da mata de galeria do Glória foram significativamente maiores do que as médias da mata de galeria do Panga. Protium heptaphyllum foi a única espécie co-ocorrente e também apresentou média significativamente maior na mata de galeria do Glória. As espécies vegetais com maiores AFE possuem uma maior captação de luz por unidade de biomassa investida, mas tendem a ter maior evaporação e perda de água. Por isso, a mata de galeria inundável, que não tem restrição hídrica para as espécies, pode apresentar maiores lâminas foliares. Com relação aos três atributos reprodutivos analisados, as áreas mostraram ser diferentes entre si e através de representação gráfica pode-se analisar que não houve padrões definidos entre as áreas, mas uma tendência a semelhanças entre várias áreas, principalmente em áreas próximas geograficamente, como as áreas de Uberlândia/MG. Quando comparados a padrões encontrados em outros estudos, as matas de galeria são semelhantes a outras áreas de floresta tropical, como alto índice de dioicia, que é relacionado a ambientes úmidos, maior porcentagem de dispersão zoocórica, especialmente por aves, e maior porcentagem de polinizadores generalistas, que são geralmente associados à dioicia.
As florestas ribeirinhas se dividem em matas ciliares e matas de galeria. As matas de galeria são importantes na manutenção dos recursos hídricos e da fauna a elas associada. Esses ambientes sofrem degradação e para a conservação e restauração são necessários estudos que entendam o funcionamento das espécies na comunidade. Os objetivos desse…

▼ We compared aboveground net primary productivity (ANPP), intercepted photosynthetically active solar radiation (IPAR), and radiation use efficiency (µ =‘ between a mixed deciduous forest and a white pine (Pinus strobus L.) plantation in the
southern Appalachian Mountains. We also examined patterns of foliage acclimation to intra-canopy light gradients, which may influence the photosynthetic radiation use efficiency (PhRUE) of forest canopies. The mixed deciduous forest had significantly
greater ANPP and µ than the pine plantation. There was no significant variation in µ across the elevation gradient in either forest. Specific leaf area of foliage was acclimated to intra-canopy light gradients. Nitrogen content and Amax was higher in
overstory trees and new pine foliage than in understory trees and one-year-old pine foliage, respectively. We found no such difference in the plasticity of SLA. Radiation use efficiency may be conservative for specific forest types across a range of
environmental conditions in the southern Appalachian Mountains.

Summary: Plant growth rates play a crucial role in vegetation dynamics, for example by influencing competitive ability, or the rate of vegetation recovery post disturbance. Plant traits are assumed to underpin variation in growth rates consistently, but most evidence comes from seedlings or closed forest vegetation. Here I aimed to test whether: (1) Trait-growth relationships are the same in adult plants as is known from seedlings; and (2) Trait-growth relationships are consistent across savannas and closed forests. I used adult growth rate and trait measurements from species in a tropical rainforest in Australia, and three tropical savanna regions (one in Australia, Brazil and South Africa). In all sites I tested clear hypotheses relating to four traits related to carbon gains and losses, namely photosynthetic rate, specific leaf area (SLA), wood density, and the ratio of leaf mass to wood mass on canopy branches. In savannas I also considered bark thickness, which is important for insulation against fire in these fire-prone systems, but assumed to be costly to growth. In tropical forests I further considered whether traits were linked to a species trajectory of growth across its lifetime. I found evidence that traits were related to adult growth rates in a predictable way in tropical forests, and that variation in trait values was linked to three distinct strategies regarding lifetime growth trajectories. Savannas showed some consistency with forests regarding trait-growth relationships, though the relative importance of traits in each site varied. I attributed differences in trait-growth patterns largely to differences in the prevailing disturbance regime in each savanna. My thesis provides strong evidence that traits have a predictable effect on the growth rates of adult plants, but that generalisations are difficult without an understanding of regional differences in ecology, evolutionary history, and disturbance regimes. These regional differences will have consequences for vegetation response to future changes in climate.

▼ Para compreender e relacionar o comportamento das espécies frente à contrastes na disponibilidade de recursos, tornam-se necessários estudos de características foliares, que têm sido propostas como indicadores do funcionamento de ecossistemas. Dentro dessa perspectiva, foi realizado um estudo com plantas adultas e jovens, em diferentes condições de ambientes, de duas espécies representativas de biomas da região sudeste do Brasil, selecionadas com base na deciduidade das folhas: Tabebuia impetiginosa (ipê) e Hymeneia coubaril (jatobá). Foram realizadas avaliações da capacidade fotossintética, teor de nitrogênio e fósforo foliar, área foliar específica, massa por área foliar e índice de matéria seca. As plantas jovens foram submetidas a diferentes condições de disponibilidade de radiação (pleno sol e sombreamento natural). Os resultados apontam que as características variaram entre as espécies conforme o grupo funcional. Os padrões temporais não apresentaram grande interferência nas respostas, sendo essas estatisticamente maiores quando as espécies foram submetidas a padrões espaciais distintos de recursos. Deve-se ressaltar que esse estudo refere-se a uma busca preliminar de informações e que esforços devem ser feitos para aprimorar metodologias que são estabelecidas com espécies de biomas brasileiros
To understand and to relate plant functioning related to contrasts in resources availability it is necessary to perform studies of leaf traits, which have been proposed as indicators of the ecosystems functioning. Within such perspective, we study adult and young individuals of two representative species of biomes of the Brazilian southeast, in different environmental conditions, selected by the deciduousness of the leaves: Tabebuia impetiginosa (ipê-roxo) and Hymeneia coubaril (jatobá). We performed evaluations of photosynthetic capacity, nitrogen and phosphorus content, specific leaf area, leaf mass per area and leaf dry matter content. The young plants were submitted to different conditions of radiation (full sun and natural shade). The results pointed that leaf traits varied among species according to the functional group.The temporal patterns of resource availability did not significantly interfered in the leaf responses across functional groups; however spatial patterns of resources availability were more expressive in defining leaf traits. It should be emphasized that this study refers to a preliminary search for information about the complex relationships among leaf traits, functional groups and resource availability and that more efforts should be applied to ameliorate methodologies that are established with species of Brazilian biomes

▼ O presente trabalho foi realizado em área de pastagem natural no município de Restinga Sêca, RS, e teve como objetivos analisar a produtividade, qualidade, composição botânica e os atributos biológicos vegetais da pastagem natural em resposta à adubação e à disponibilidade hídrica. A adubação aumentou a produtividade da pastagem nativa. A taxa de acúmulo de MS Total tanto na área seca como na úmida, ambas adubadas foi de 102 kg/ha/dia. Nas mesmas áreas, não-adubadas, foi de 47 e 41 kg/ha/dia, respectivamente. Com relação ao material verde, a adubação também aumentou a produtividade chegando a taxas de acúmulo diária de 70 e 93 kg/ha para área seca e úmida, respectivamente, nessas áreas não-adubadas, as taxas foram de 29 e 25 kg/ha/dia. Além disso, aumentou o índice de nitrogênio e de PB nos tecidos vegetais e a quantidade de MM nas parcelas. A disponibilidade hídrica influenciou nos componentes da pastagem, quanto maior a disponibilidade de água, menor a quantidade de componentes como folha estreita, folha larga e leguminosas e maior a quantidade de FDN nos tecidos, principalmente no período de primavera. Tanto a adubação como a maior disponibilidade hídrica diminuíram a riqueza de espécies, fazendo com que algumas espécies adaptadas a essas condições dominassem a comunidade. Formaram-se dois grupos funcionais a partir dos atributos biológicos vegetais, um grupo de captura de recursos, com alta AFE (26) e baixo TMS (234), onde fazem parte as espécies Paspalum pumilum, Paspalum urvillei, Paspalum pauciciliatum, Axonopus affinis e Setaria glauca. O outro grupo é de conservação de recursos, com baixa AFE (21) e alto TMS (323), onde Paspalum notatum e Andropogon lateralis foram as espécies agrupadas.
This study was conducted in the city of Restinga Sêca, RS, with the objective to analyze the productivity, quality, botanical composition and biological characteristics of native pasture in response to fertilization and water availability. The fertilization increased native pastures productivity. The dry matter total accumulation rate, at dry or wet area, both fertilized, was 102 kg/ha/day. In the same areas, not fertilized, was 47 and 41 kg/ha/day, respectively. For green matter, the fertilization also increased the productivity, reaching accumulation rates of 70 and 93 kg/ha/day for dry and wet areas, respectively. In these not fertilized areas, the rates were 29 and 25 kg/ha/day. Furthermore, increased nitrogen and crude protein rates in plant tissues and mineral matter quantity in the plots. Water availability influenced on pasture components, as the water availability was increased, lower amount of components such as strait leaf, broad leaf and legumes and higher amount of neutral detergent fiber in tissues were observed, especially in spring period. Fertilization as well as water availability decreased the wealth of species, causing domination of some species already adapted to these conditions. Two functional groups were formed with vegetal biological characteristics, a group of capture of resources, with a high…

▼ Castanea dentata once dominated the eastern deciduous
forest, but was virtually eliminated by the exotic fungus,
Cryphonectria parasitica. We compared C. dentata's morphological
and
leaf chemistry traits to those of formerly co-occurring
species. Seedlings of C. dentata, Q. rubra and L. tulipifera were
grown in varying light and nitrogen regimes. After four months of
growth, we measured
specific leaf area, biomass, plant height and
leaf nutrient content of each seedling. Castanea dentata attained
greater height, biomass and leaves per plant than the other two
species in most light treatments (P < .001). Results also
revealed several other traits and tradeoffs of the three species.
Castanea dentata's ability to accumulate greater biomass and height
at the seedling stage of development may explain a great deal about
its former dominance. Results also suggest that C. dentata will be
able to thrive in a wide variety of intact forests when
reintroduction experiments begin.

▼ O uso intensivo e desordenado dos recursos naturais está colocando em risco muitos biomas, como o Cerrado. Por isso, a restauração de ambientes degradados é uma atividade crescente, sendo cada vez mais necessária e imprescindível para a conservação da biodiversidade. O objetivo deste estudo foi avaliar a história de vida e a capacidade adaptativa de espécies de duas áreas em restauração comparadas com indivíduos controle, ou seja, indivíduos encontrados em áreas de vegetação original do Cerrado. As espécies deste estudo fazem parte de uma lista de espécies arbóreas utilizadas pelo Programa Buriti, para a restauração ambiental da mata ciliar da Bacia Hidrográfica do Rio Uberabinha. Foram selecionadas 5 espécies na Área 1 (Croton urucurana, Guazuma ulmifolia, Inga laurina, Inga sessilis e Tabebuia roseo-alba) e 10 espécies na Área 2 (Cecropia pachystachya, Croton urucurana, Guazuma ulmifolia, Inga laurina, Inga sessilis, Luhea divaricata, Myrsine umbellata, Tapirira guianensis, Tabebuia roseo-alba e Trema micrantha), sendo essas as mais representativas e que melhor se adaptaram às duas áreas estudadas. Foram avaliados os atributos vegetativos e reprodutivos de cada uma delas, para se verificar a diversidade de atributos nas duas áreas em restauração. Cinco indivíduos de cada uma dessas espécies tiveram o diâmetro e a altura aferidos e 5 a 10 folhas jovens totalmente expandidas foram coletadas de cada um, para avaliação dos traços foliares funcionais. Para isso, a área foliar específica (AFE) foi mensurada através da razão área foliar (mm2)/massa seca(mg) para cada uma das folhas dos indivíduos coletados. Foram necessárias imagens digitalizadas das folhas (Image J) para obtenção da área foliar. Já a massa seca foi obtida através de pesagem após essas folhas ficarem por um período de no mínimo 48 horas em estufa a 70o C. O comprimento do pecíolo (CP) foi estimado pelas mesmas imagens usadas para a obtenção da área foliar. Para a análise dos dados foram utilizados testes paramétricos, ANOVA e Teste T, e não-paramétricos, Kruskal-Wallis e Mann-Whitney, quando os pressupostos não foram atendidos. A diferença entre as médias foi feita através do teste de comparações múltiplas de Tukey a 5% de significância. O coeficiente de variação de cada espécie também foi calculado para medir a variabilidade intraespecífica entre as amostras de uma mesma espécie. Houve diferenças significativas entre as espécies das duas áreas e entre o controle, para a maioria das espécies estudadas. A AFE e o CP, ao contrário do que se espera para espécies sob luminosidade intensa, em esses dois atributos foliares possuem valores menores do que espécies sob condições de sombreamento, foram significativamente maiores na Área 2 (luminosidade intensa) do que no controle (sombreamento) e na Área 1 (luminosidade intensa). Entretanto, grande parte das espécies na Área 1 tiveram AFE e o CP igual ou menor do que o controle e do que as espécies da Área 2. Este estudo indica que estas espécies apresentam diversidade de atributos necessários ao restabelecimento…

▼ Fire is often a characteristic of the brazilian cerrado and the survival of species to fire is determined by its anatomy, physiology and behavioral, further by post-fire environmental characteristics. Few attributes are related to cerrado species survival to fire, such as, specific leaf area and suber density and thickness. Comparative studies involving species identification and floristic classification between areas under different burning frequencies are important due their capacity to identify the potential of species to have phenotypic plasticity in response to fire. The study aimed to compare the structure of two areas of cerrado sensu stricto under different degrees of disturbance by fire, using ecological parameters that respond to this disturbance such as specific leaf area and suber density and thickness. The study was based on surveys conducted by Faleiro in 2007. Species analyzed in the study were selected by IVC, totaling 22 species in the area without fire and 18 in the area with fire occurrence, with 13 co-occurring species between the two areas. Means of ecological attributes between co-occurring species in areas were compared (T test). A functional approach was done through graphical analysis of species distribution for each ecological attribute and functional groups were formed by UPGMA (Jaccard). Among the 13 species common in the two areas, five of them differ in specific leaf area between areas with and without fire. For suber density, S. ferrugineus showed differences between the two areas. For suber thickness, Qualea multiflora and Styrax ferrugineus showed different between the two areas. About functional grouping, no groups were formed by the frequency of fire. The fire acted as a modeler agent in some species of this community, however no pattern of responses was found for this community.
fogo frequente é uma das características dos cerrados e a sobrevivência das espécies ao fogo é determinada por suas características anatômicas, fisiológicas e comportamentais, além das características ambientais pós-fogo. Alguns atributos estão relacionados com a sobrevivência das espécies ao fogo, como área foliar específica, densidade do súber e espessura do súber. Estudos comparativos que envolvam a identificação de espécies e classificações florísticas entre áreas sob diferentes frequências de queimadas são importantes, uma vez que destacam possíveis plasticidades das espécies ao fogo. O estudo visou comparar a estrutura de duas áreas de cerrado sentido restrito sob diferentes graus de perturbação por fogo, utilizando parâmetros ecológicos que respondem à essa perturbação como área foliar específica, densidade e espessura do súber. O estudo partiu de levantamentos realizados por Faleiro em 2007. As espécies a serem analisadas no estudo foram selecionadas pelo IVC, totalizando 22 espécies na área denominada sem fogo e 18 na área denominada com fogo, sendo 13 espécies co-ocorrentes entre as duas áreas. Foram comparadas as médias dos atributos ecológicos entre as espécies co-ocorrentes nas áreas sem…

▼ Plant functional types defined from morphological attributes are fundamental to understanding functioning of grasslands communities. Thus, to build a classification based solely on grasses (family of greater biomass contribution), it is necessary for increasing the knowledge about complex ecosystems. This work aims to characterize vegetation dynamics by species and by functional types of grasses of two RS physiographic regions (Depressão Central-Santa Maria and Campanha-Bagé) under different managements. The evaluated treatments were: natural pasture and natural pasture overseeded with cool season species (Bagé) and natural pasture submitted to burning and grazing treatments (Santa Maria). For this, permanent transects were used in order to represent the different communities at paddock level. Vegetation dynamics was evaluated using procedures of BOTANAL method. Tillers of grasses with contributions exceeding 3% of total aboveground biomass were collected for subsequent measurement of the attributes specific leaf area (AFE) and leaves dry matter content (TMS). Burned treatments presented greater contribution of Andropogon lateralis, while in grazed treatments there was a greater species diversity. Introduction of cool season species combined with fertilizer promotes an increase of species characterized by resources capture. TMS was more stable for species linked to capturing resources strategy and AFE was more robust for species characterized by resources conservation. Therefore, until a regional data basis were developed, it is recommended to use both attributes for future research.
Tipos funcionais de plantas definidos a partir de atributos morfológicos são fundamentais para o entendimento do funcionamento de comunidades campestres. Desta maneira, a construção de uma tipologia baseada apenas em gramíneas (família de maior contribuição), torna-se necessária para o avanço do conhecimento sobre ecossistemas complexos. Este trabalho tem por objetivo caracterizar duas regiões fisiográficas do RS (Depressão Central-Santa Maria e Campanha-Bagé) sob distintos manejos quanto à dinâmica vegetacional por espécies e por tipos funcionais de gramíneas. Os tratamentos avaliados foram: pastagem natural e pastagem natural com introdução de espécies hibernais (Bagé) e pastagem natural submetida a tratamentos de queima e pastejo (Santa Maria). Para isto, foram dispostas transectas fixas de modo a representar as diferentes comunidades em nível de potreiro. Foi avaliada a dinâmica vegetacional utilizando os procedimentos do método BOTANAL. Foram coletados afilhos das gramíneas com contribuição superior a 3% da biomassa aérea total para posterior medida dos atributos área foliar específica (AFE) e teor de matéria seca da folha (TMS). Os tratamentos queimados tiveram maior contribuição de Andropogon lateralis, enquanto nos tratamentos pastejados houve uma maior diversidade de espécies. A introdução de espécies de estação fria, aliada à adubação, promove um acréscimo das espécies caracterizadas por captura de recursos. O TMS se mostrou…

▼ An effective plant nutrient management strategy optimises nitrogen (N) use efficiency for minimised environmental impact, while ensuring an optimum N status of the crop for good product quality and maximum growth. Soil or plant analysis can be used to evaluate the strategy; however the use of plant analysis for this purpose has been limited. One reason is lack of reliable reference values for the critical concentration needed for optimal growth. This study builds on theories that relate ontogenetic changes in the critical N concentration to changes in the relation between mass and surface area of the entire plant and of individual leaves. Through the establishment of critical N concentrations on the basis of these theories, some of the drawbacks hitherto experienced with plant analysis, such as difficulties in defining growth stage or plant part to sample, can be avoided. The aim of this thesis was to establish critical N concentrations for white cabbage (Brassica oleracea L. var. capitata L. f. alba D.C.) on the basis of these theories. Multi-N-rate and multi-harvest experiments were conducted in the field and in a climate chamber. The results showed that the critical N concentration declined at the same rate (-0.33) as the plant's leaf area ratio (leaf area divided by plant mass), which is in agreement with the 2/3-Power rule or "skin-core" hypothesis. The critical N concentration (% of DM) on a whole plant basis was estimated to 4.5 (W<1.5 t ha-1) and to 5.1W-0.33 (W>1.5 t ha-1), where W is weight per unit area of plant dry matter exclusive of roots. Moreover, it was concluded that the unshaded horizontally orientated leaves of cabbage can be used for leaf area based plant analysis of individual leaves. The critical N concentration of these leaves expressed on an area basis was found to be 3.7 g N m-2, while that for the whole plant N on a leaf area basis was 4.7 g N m-2. The ratio of these two critical concentrations, 0.8, was similar to the leaf N ratio (leaf N/whole plant N) of young plants before self shading occurs.

▼ Arealgröße ist eine zentrale Eigenschaft der Biogeographie von Tier- und Pflanzenarten. Warum manche Arten weit verbreitet sind, während andere, oft nahe verwandte Arten nur kleine Gebiete besiedeln ist eine Frage, die die Ökologie seit langem beschäftigt, aber bis heute nicht vollständig beantwortet ist. Unter den verschiedenen Faktoren, die in diesem Zusammenhang diskutiert worden sind, spielt auch die Breite der ökologischen Nische eine wichtige Rolle. Es wird im Allgemeinen davon ausgegangen, dass Arten die mit unterschiedlichen Umweltbedingungen zurecht kommen, auch größere geographische Areale besiedeln können, d.h. dass größere Areale mit breiteren ökologischen Nischen positiv korreliert sind.
Die Nischenbreite wird neben anderen Faktoren durch die funktionellen Eigenschaften bestimmt, welche Arten im Laufe ihrer Evolutionsgeschichte erwerben. Interspezifische Unterschiede bezüglich funktioneller Eigenschaften können aus zwei Gründen zu Untschieden in der Nischenbreite führen: Erstens könnten bestimmte funktionelle Eigenschaften die Konkurrenzkraft von Arten oder ihre Umwelt-Tolernaz erhöhen; und zweitens könnte eine höhere intraspezifische Variabilität funktioneller Eigenschaften den Arten Anpassung an mehr unterschiedliche Lebensräume ermöglichen.
In meiner Doktorarbeit untersuchte ich zwei Hypothesen bezüglich der Effekte funktioneller Eigenschaften auf Nischenbreiten und Arealgrößen von neotropischen Baumarten. Meine erste Studie beschäftigte sich mit dem Zusammenhang zwischen Arealgröße und den Mittelwerten funktioneller Eigenschaften in einer Gruppe von 35 tropischen Bäume, die gemeinsam im südlichen Costa Rica vorkommen. Ich sammelte Daten zu diesen Eigenschaften von regionalen Populationen dieser Arten und verglich sie mit der ihrer gesamten Arealgröße. Ich fand negative Auswirkungen von hoher Holzdichte und geringem Blattstickstoffgehalt auf die Arealgröße. Meine Schlussfolgerung war, dass ein konservativer, sparsamer Umgang mit Ressourcen die Arealgröße einschränkt. Die Korrelation ist allerdings nur schwach ausgeprägt, ein konservativer Umgang mit Ressourcen kann daher nur einer von mehreren Faktoren sein, die die Arealgröße dieser Arten beeinflussen.
Innerhalb derselben Gruppe von Baumarten und mit den selben von mir erhobenen Daten untersuchte ich, ob die intraspezifische Varianz derselben funktionellen Eigenschaften die Unterschiede in der Größe ihrer Areale erklären könnten. Ich konnte für keine funktionelle Eigenschaft signifikante Unterschiede bezüglich intraspezifischer Variation zwischen Arten mit kleinen oder großen geographischen Arealen finden. Meine Schlussfolerung war, das die höhere Variabilität, von der bei weit verbreiteten Arten berichtet wurde, aus sukzessive lokalen Anpassungen während der Arealgeschichte resultiert und daher eher ein Effekt als eine Ursache großer Areale darstellt.
In meiner dritten und letzten Studie benutzte ich Daten zu drei funktionellen Eigenschaften einer größeren Anzahl von neotropischen Baumarten, um den Zusammenhänge von Mittelwerten und…

▼ As a major component of whole-plant hydraulic conductance, without understanding root hydraulic properties, it would be impossible to understand hydraulic responses and growth of shoots to the changes in resource availability. The first
study examined the impacts of atmospheric [CO2] and soil fertility on hydraulic conductivity (K) in stems, taproots and fine roots in Pinus taeda L. seedlings. The differences in K resulting from different resource availability were related to xylem
anatomy. Higher stem K was associated with increased tracheid lumen diameter by high fertility. Taproot tracheid lumen diameter was larger than that in stems. Fine roots had larger individual tracheid lumen diameter but smaller root radius in the
elevated [CO2] and high fertility treatment compared to other treatments. K of fine roots were more than 2-fold higher under elevated [CO2] and high fertility compared with other treatments, suggesting conductivity was primarily increased in fine roots
by an increase in tracheid lumen diameter. Both stem and taproot K was positively related to most of the parameters we measured in tree growth and leaf gas exchange under different treatments. When plant species grow in natural ecosystems, intra- and
interspecific root interaction is inevitable. In the second study, we measured k in the entire root system (kR) of two co-occurring plants. Root-specific hydraulic conductance (kS) was calculated by dividing kR by the biomass of entire root system. Pinus
taeda and Quercus pagoda seedlings were planted in pots to create conditions of intra- or interspecific root interaction, or no interaction. High or low rates of fertilization were applied to each interaction treatment. The Q. pagoda seedlings under
interspecific root interaction and low fertility increased kR by developing larger root systems, while P. taeda seedlings under interspecific interaction and high fertility increased kR by increasing kS. Higher kR of P. taeda seedlings under
intraspecific interaction and high fertility was also associated with larger root systems. This is similar with the observation from mature P. taeda trees in the field: those growing under intraspecific interaction and high fertility had highest fine
root k and growth rate compared to the other treatments.

▼ Africa's miombo woodlands constitute one of the most important dry tropical forests on earth, yet the hydraulic function of these woodlands remains poorly researched. Given the current predictions of increased aridity by the end of this century in the miombo ecoregion, understanding the likely response of miombo woodlands tree species to water stress is crucial in planning adaptation strategies. Predicting the response of miombo woodlands to future climate trends is hampered by a lack of knowledge on the physiology of the common miombo woodlands tree species. In particular, plant-water relations for this woodlands type are not well understood. An understanding of plant-water relations for this woodlands type will provide insights into how water limits tree species distribution in this ecosystem. This will also improve our prediction model on the likely response of this ecosystem to predicted climate change. For this reason, the overall objective of this research was to evaluate the hydraulic architecture and xylem vulnerability to cavitation for nine principal miombo woodlands tree species differing in drought tolerance ability and habitat preference. This was achieved by; examining the hydraulic properties and evaluating the extent to which each hydraulic design was vulnerable to water stress-induced xylem cavitation; investigating how seasonal changes in plant-water relations influences seasonal patterns of leaf display and; analyzing the relationship between stem hydraulic supply and leaf functional traits related to drought tolerance ability. This research has found that drought-intolerant tree species with mesic specialization have more efficient stem hydraulic systems than co-occurring habitat broad ranging species. Broad ranging tree species attain wider habitat distribution by adjusting their hydraulic supply in response to changing ecosystem water availability. The finding that hydraulic properties differ significantly between tree species with contrasting habitat preference suggests that tree hydraulic design may have some adaptive ecological role in influencing species habitat preferences in miombo woodlands. The evaluation of xylem vulnerability to cavitation revealed that mesic specialized tree species were more vulnerable to water stress-induced cavitation than habitat broad ranging tree species. Vulnerability to cavitation in individuals from the same broad-ranging species growing in contrasting habitats showed only marginal and statistically insignificant (P > 0.05) differences between wet and dry sites. In the investigation of the influence of seasonal changes in stem water relations on seasonal leaf display, seasonal rhythms in stem water status were found to exert significant controls on leaf phenology. Mesic specialists had strong stem water controls throughout the year in comparison to broad ranging tree species. An analysis of the relationship between stem hydraulic supply and leaf functional traits suggests that stem hydraulic supply constrains leaf biomass allocation patterns among miombo tree…

▼ In order to restore ecosystems, we must have reliable monitoring indicators to identify the success of ecological restoration, and make effective management decisions. Indicators must be simple and inexpensive to measure to allow for practical industry use, account for ecological and environmental change, and provide direction to ecosystem managers. Trait-based monitoring approaches have been proposed as an alternative measure to traditional vegetation monitoring indicators (e.g. measures of species diversity), as they provide more information about the function of an ecosystem and their abiotic-biotic interactions. The literature indicates that plant functional traits, which explain how an organism acquires, processes and invests in resources, may be an ideal monitoring indicator.
I examined the practical application of plant traits to assess restoration success in a phragmites managed Great Lakes Coastal Wetland, in the face of significant management and ecological variability. Two traits often cited in the literature, specific leaf area and leaf dry matter content, were measured in open marsh and three created ponds of different ages, and in plots treated with glyphosate and plots left un-treated. Non-parametric Mann-Whitney U and Kruskal Wallis tests were used to compare the community weighted mean trait values of ponds and open marsh, and between herbicide treatment groups. Notable results included an increase in specific leaf area after herbicide treatment, and a decrease in leaf dry matter content, suggesting that traits promoting biomass production may be favoured after herbicide treatment. This is consistent with previous studies comparing weighted means after management action, as well as in successional trait studies. However, it will be important to consistently monitor invasive species presence and management actions, in order to confirm that trait changes are due to herbicide treatment. No statistically significant differences were found between ponds and open marsh for specific leaf area, and leaf dry matter content only differing significantly in one pond. Possible explanations for this lack of change and the variable changes between ponds include intraspecific variation, environmental factors like water level fluctuations, and management variation between ponds.
To conclude, the use of leaf traits, and plant traits in general, are possible as a restoration monitoring measure, but their use is highly site specific. They are best suited in situations where variability is low; where they can be compared against a measureable environmental gradient or a well identified management regime, two factors that do not always exist in a practical resource management context. Time also plays a role in the application of traits to restoration projects; the more traits that can be measured, and more resources allocated to the understanding and application of additional functional diversity indices, the more valuable their use. Future research and management opportunities include the integration of trait-based…

▼ CAPÍTULO 1: As variáveis ambientais do sub-bosque condicionam o desenvolvimento de uma flora e, consequentemente, de uma estrutura funcional muito específica para este estrato. Este estudo avaliou a diversidade florística e a fenologia foliar e síndrome de dispersão das espécies arbóreas em nove sub-bosques de florestas estacionais semideciduais sob diferentes estádios de perturbação e testou a hipótese de que o aumento na intensidade de perturbação da comunidade afeta diretamente a diversidade florística e a estrutura funcional dos sub-bosques. Foram avaliados os parâmetros fitossociológicos das espécies e famílias, e a estrutura de cada sub-bosque e nos sub-bosques como um todo. A similaridade florística foi avaliada entre os nove sub-bosques e, entre os sub-bosques sob mesma intensidade de perturbação. A fenologia foliar e síndrome de dispersão das espécies foi comparada entre o sub-bosque e os estratos superiores em cada área e, entre os sub-bosques. Os resultados apontaram Myrtaceae, Rubiaceae, Celastraceae, Siparunaceae e Meliaceae como as cinco famílias mais importantes. As cinco espécies mais representativas foram Cheiloclinium cognatum, Cordiera sessilis, Siparuna guianensis, Siphoneugena densiflora e Trichilia catigua. As análises de similaridade florística mostraram maior similaridade florística entre os sub-bosques sob mesma intensidade de perturbação e que, algumas espécies e famílias podem ser indicadoras do estádio de perturbação do sub-bosque. As comparações de fenologia foliar e síndrome de dispersão mostraram uma proporção muito baixa de espécies decíduas e anemocóricas no sub-bosque em relação aos estratos superiores. Nas comparações destes traços entre os sub-bosques, observou-se um aumento significativo nas proporções de espécies decíduas nos estádios mais perturbados, mas não nas proporções de espécies anemocóricas. Os resultados obtidos mostraram que, mesmo com diversidades florísticas muito distintas, foi possível estabelecer padrões funcionais relacionados à fenologia foliar e síndrome de dispersão dos sub-bosques e, sugerem que a análise destes traços pode servir como parâmetro na classificação dos estádios sucessionais das florestas estacionais semideciduais em uma perspectiva global de comparação. CAPÍTULO 2: As espécies de sub-bosque, um ambiente tipicamente sombreado, apresentam traços funcionais que potencializem a fotossíntese sob baixas intensidade de luz. O provável aumento da disponibilidade de luz no sub-bosque com o aumento da intensidade de perturbação provoca alterações nos traços funcionais foliares e de arquitetura arbórea, relacionadas à captação e utilização da luz das espécies deste estrato. Também é esperado que a seleção de espécies nos sub-bosque sob diferentes intensidades de perturbação favoreça grupos de espécies com características funcionais diferentes. Este estudo avaliou a influência da intensidade de perturbação nos traços funcionais foliares (área foliar, conteúdo de matéria seca e área foliar específica), da arquitetura da copa e da densidade de madeira das…

▼ Increased nutrient availability globally has the potential to affect community functional composition of plants in nutrient limited environments, such as coastal grassland systems. Stability of these systems are threatened worldwide by urbanization, as well as effects of sea level rise and increased frequency and intensity of storms, and atmospheric N deposition, associated with climate change. Annual net primary productivity (ANPP), species composition, and functional traits (community weighted
specific leaf area (CWSLA),
leaf area index (LAI), growth form and photosynthetic pathway) were measured across four treatments to assess multiple resource limitation of nitrogen (N) and phosphorus (P) and functional community response in a coastal grassland on Hog Island, VA within the Virginia Coast Reserve, Long Term Ecological Research Network (LTER) applied at a rate of 10 g m
-2 yr
-1 Nutrient enrichment did not alter species diversity or richness. ANPP was highest in plots receiving any type of nitrogen enrichment, and was higher than expected of low nutrient systems. CWSLA was significantly higher in NP plots, and was lower than other grasslands. P treatments were not significantly different from controls. Graminoid species, specifically C
4 species responded with higher ANPP than C
3 forbs or graminoids within treatments. Evidence of synergistic NP effects were seen on community level resource allocation and
leaf construction, but no significant species changes occurred over a 1-year time span. These results have expanded the knowledge of functional response to increased nutrient availability in an understudied, coastal grassland, which are at high risk to being lost to sea level rise and anthropogenic development and inform community assembly processes in stressful environments.

▼ Andean montane forests are one of the most diverse ecosystems on Earth, but are also highly vulnerable to climate change. Therefore, the link between plant distribution and ecosystem productivity is a critical point to investigate in these ecosystems. Are the patterns in productivity observed in montane forest due to species turnover along the elevational gradients? Methodological constraints keep this question unanswered. Also, despite their importance, belowground biomass remains poorly quantified and understood. I measured two plant functional traits in seedlings, root:shoot ratio and
specific leaf area, to identify different strategies in growth and biomass allocation across elevations. A tradeoff in
specific leaf area with elevation was found in only one species, and no generalized directional change was detected with elevations for root:shoot ratio. Lack of information for the ontogeny of the measured plant traits could confounding the analysis.

▼ Growth and development of potato (Solanum tuberosum L.) crops after different cool season storage. Tuber yield variation has been attributed to seed potato physiological age in numerous studies on potato. Seed potato physiological age has been defined as the developmental stage of a seed potato, or physiological state which influences production capacity and causes major impacts on potato yields. Physiological age is reportedly determined by genotype, chronological age and environmental conditions (especially temperature) during the storage phase. The temperature sum (or thermal-time) accumulated by the seed potato during the storage period can been used as a measure of physiological age. Manipulating seed potato physiological age may be an effective method to alter tuber yield and yield distribution for many cultivars. One important way to manipulate physiological age is to expose the seed potatoes to different temperature regimes during the storage phase. Therefore, an assumption of this study is that physiological age can be measured through quantification of accumulated thermal-time through development processes, from harvest to planting. These, in turn, are then expected to impact potato yield and size (or the grade size of each potato, which determines the yield size distribution). The rationale of the research is that contrasting seed potato storage regimes will provide different physiological ages at the time of planting. This may affect crop growth and development in the field and potentially affect tuber yield and yield distribution for different cultivars. The hypothesis to do this is; if seed potato physiological age is an important source of yield variation it must impact on at least one of the parameters of yield; i.e. cumulative amount of radiation intercepted by the canopy (Rcum), radiation use efficiency (RUE) or partitioning (harvest index; HI). First, a field experiment (Experiment 1, or Benchmark experiment) under non-limiting growth conditions benchmarked the mechanisms of potato growth, development, yield and yield distribution for three commercial cultivars (‘Bondi’, ‘Fraser’ and ‘Russet Burbank’). In New Zealand, ‘Bondi’ has high yield ability, which interests growers. However tubers may be too long, which is a complaint of processors. ‘Fraser’ has excellent long-term storage attributes with resistance to cool temperature sweetening. However, the difficulty of getting high tuber yields is seen as a disadvantage by the potato growers. ‘Russet Burbank’ was included in Experiment 1 to benchmark results internationally because is used worldwide as the standard for French fries and consequently there is extensive scientific literature about this cultivar. The objective of Experiment 2 was to generate ‘Bondi’ and ‘Fraser’ seed potatoes of different physiological ages from contrasting storage regimes (treatments). At the end of storage the seed potatoes from the different treatments had accumulated 972 and 2249 °Cd and their sprouting patterns were assessed for differences. Half of the potatoes of…

▼ Abstract: The Cerrado and the Atlantic Rainforest are contrasting environments in terms of water, light and nutrient availability. Thus some adaptive traits for seedling growth and
leaf morphology and anatomy are expected for each habitat. In this work a comparative study was performed between the Cerrado and the Atlantic rainforest species using congeneric pairs .Each pair was composed by a species from the Cerrado and a species from the Atlantic Rainforest. Seedling growth was studied in 10 pairs from 8 families, mature
leaf functional morphology was studied in 14 pairs from 11 families and
leaf anatomy was studied in 8 pairs from 7 families. For seedling growth studies,
specific leaf area (SLA),
leaf area ratio (LAR), root mass ratio (RMR), stem mass ratio (SMR),
leaf mass ratio (LMR), root/shoot ratio (R/S), relative growth rate (RGR) and net assimilation rate (NAR) were calculated. For the study of light stress effect on seedling growth it was used a congeneric pair of species: Eriotheca candolleana (from the Atlantic Rainforest) and Eriotheca gracilipes (from Cerrado). Two irradiance levels were performed (50% and 2%) For the evaluation of mature
leaf functional morphology, succulence, SLA,
leaf thickness and
leaf width were measured. For the anatomy studies, images from
leaf transversal cross section were digitalized and analised using the software image pro plus. There were adaptive convergences for some traits relative to the habitat. Higher RGR, SLA and LAR values were generally achieved for species from the Atlantic Rainforest. SLA and LAR are closely related to light interceptance for plant growth. It was not found an association between root investiment and species environment. It was observed that leaves of Cerrado species were more succulent and presented lower values of SLA. SLA data found in mature leaves showed the same pattern obtained for the seedlings. Cross sections of the leaves revealed higher lamina thickness and higher mesophyll thickness. A more condensed parenchyma was generally found for the Cerrado species. The lignified proportion of leaves was also higher in plants from the Cerrado. Thick and more lignified leaves decrease light interception and reduce growth rates. Such traits are of important adaptive value in environments where water and nutrients are limiting resources

▼ A expansão da floresta sobre o campo, a partir do estabelecimento de araucárias isoladas (nucleação), forma uma paisagem única no planalto sul-brasileiro, sendo que o uso de uma abordagem de metacomunidades pode auxiliar a compreender melhor esse processo. Existem quatro modelos de metacomunidades que explicam a relação entre comunidades locais: dinâmica de manchas, seleção de espécies, efeitos de massa e neutro. Esses modelos possuem diferentes premissas quanto aos processos de nicho e de dispersão que atuam na dinâmica da metacomunidade. No entanto, há uma lacuna entre a teoria e o teste desses modelos em estudos empíricos. Uma forma de testar mais claramente esses modelos é através de uma abordagem funcional. Nesse contexto, o objetivo do trabalho foi avaliar a importância (i) de atributos relacionados às estratégias de dispersão e de crescimento das espécies, (ii) da abundância das espécies no pool regional e (iii) do tamanho da mancha, na organização de comunidades de indivíduos lenhosos juvenis em áreas de nucleação florestal sobre o campo, a fim de compreender quais modelos de metacomunidades melhor explicam esse processo. Para tanto, calculamos o CWM (Community Weighted Mean) e índices de diversidade funcional, considerando a ocorrência (sesFD) e a abundância (sesFDis) das espécies, para tamanho da semente e área foliar específica (SLA), em manchas florestais de distintos tamanhos e na floresta contínua adjacente ao campo, e testamos se as áreas diferem entre si de acordo com o tipo de ambiente. Avaliamos ainda se a abundância relativa das espécies nas áreas de nucleação é determinada pela abundância das mesmas na floresta contínua, através do uso dos modelos de Community Assembly by Trait Selection (CATS). Os resultados foram então comparados com o esperado para cada modelo de metacomunidade. A maior parte dos sítios apresentou índices de diversidade funcional para SLA e tamanho da semente de acordo com o esperado ao acaso. As áreas não diferiram quanto ao CWM para SLA. No entanto, foram observadas diferenças quanto ao CWM para o tamanho da semente, com o favorecimento de espécies com sementes menores em áreas mais abertas, e espécies com sementes maiores em áreas mais sombreadas. De acordo com os modelos CATS, a abundância das espécies no pool regional foi mais importante do que os atributos para a determinação da abundância das mesmas nas comunidades locais. Concluiu-se que o modelo de metacomunidades que melhor explica o processo de nucleação florestal sobre o campo no planalto das araucárias é o modelo de efeitos de massa, o que ressalta a importância da dispersão para a estruturação das comunidades locais. Como a maior parte das espécies lenhosas existentes na área possui dispersão zoocórica, esse resultado indica que a preservação da fauna dispersora é fundamental para a dinâmica desse ecossistema. Com o uso de uma abordagem funcional, em conjunto com os modelos CATS, foi possível testar os quatro modelos de metacomunidades. Assim, o método proposto pode ser aplicado a outros sistemas naturais,…

▼ Grasses are widely used in revegetation to control erosion, build soil and maintain habitat. In northeast British Columbia, non-native grass species are commonly seeded to reclaim industrially disturbed sites. Widespread concern about degradation of biodiversity and key ecological processes has led to increasing value placed on native species and management practices leading to a more resilient landscape.
I undertook this study to fill the restoration knowledge gap relating to native grasses in northeast BC. I did an extensive inventory of grasses on 217 sites in 2007, 2008 and 2009. Functional traits were measured in the field and in a greenhouse growth experiment. I found ninety-nine grass species occuring in the region, 70% of which are native. The number, proportion and extent of non-native grasses are increasing and four of these – Poa pratensis, Festuca rubra, Bromus inermis, and Phleum pratense represented almost a quarter of all occurrences. Several native species were common throughout the region: Calamagrostis canadensis, Leymus innovatus, Elymus trachycaulus, Poa palustris and Agrostis scabra. Other native species, including Festuca altaica, Koeleria macrantha, Pascopyrum smithii, and Schizachne purpurascens, strongly favoured intact habitats.
Elevation, soil moisture regime, proportion of bare ground, and land use were significant factors related to local grass species composition and abundance. Agrostis scabra, Alopecurus aequalis, Beckmannia syzigachne, Bromus ciliatus, Cinna latifolia, Deschampsia cespitosa, Elymus alaskanus, Elymus trachycaulus, Festuca saximontana and Hordeum jubatum grew commonly on severely damaged well sites.
Field measurements for
Specific Leaf Area (SLA) and
Leaf Dry Matter Content (LDMC) of 11 species showed an inverse correlation. Bromus ciliatus, Bromus pumpellianus, and Elymus trachycaulus had high SLA/low LDMC linked to rapid growth, whereas Festuca altaica, Deschampsia cespitosa, and Calamagrostis stricta had low SLA/high LDMC linked to slow growth and persistence.
In the greenhouse experiment, Poa palustris, Cinna latifolia and Bromus ciliatus produced the most overall biomass and Pascopyrum smithii and Poa palustris produced the greatest aboveground biomass. Calamagrostis stricta, Poa palustris, Elymus glaucus, Leymus innovatus and Pascopyrum smithii exhibited clonal growth. Beckmannia syzigachne, Bromus ciliatus Cinna latifolia produced viable seed during the 135-day experiment.
Considering all attributes five native species, Calamagrostis canadensis, Elymus trachycaulus, Poa palustris, Leymus innovatus, and Agrostis scabra are recommended for general restoration use in northeast B.C. Other native species show promise when matched to particular site conditions, including Alopecurus aequalis, Arctagrostis latifolia, Beckmannia syzigachne, Bromus ciliatus, Calamagrostis stricta, Cinna latifolia, Deschampsia cespitosa, Elymus glaucus, Festuca saximontana, Glyceria striata, Hordeum jubatum, Koeleria macrantha, Pascopyrum smithii, Poa alpina, Schizachne…
