A busca de padrões consistentes na natureza tem sido a principal meta dos ecólogos. Essa dissertação teve como objetivo usar abordagens filogenéticas na tentativa de compreender melhor o processo ecológico da expansão florestal sobre áreas abertas. O uso da informação filogenética em análises ecológicas considera as espécies não independentes umas das outras, pois estas compartilham grande parte da história evolutiva. Essa hierarquia de organização das espécies é muito importante para determinar as regras que governam os processos de montagem das comunidades locais. Nesta dissertação foram avaliados padrões filogenéticos de estruturação da vegetação lenhosa florestal ocorrente em ecótonos de áreas abertas com vegetação florestal distribuídos em diferentes regiões do extremo sul do Brasil. Estes ecótonos são formados por diversas formações florestais, as quais tendem a expandir sobre as áreas abertas. Dados sobre composição de espécies provieram de estudos já realizados e de amostragens em alguns sítios. Duas métricas filogenéticas complementares foram usadas para avaliar a estrutura filogenética em cada categoria de habitat nos ecótonos: índice de parentesco líquido (NRI) e coordenadas principais da estrutura filogenética (PCPS). As análises dos valores de NRI não mostraram um padrão nítido de estruturação filogenética das comunidades. Já a análise dos PCPS mostrou padrões consistentes nas três escalas espaciais abordadas e independente da composição de espécies. Clados basais associaram-se às áreas florestais, enquanto clados de diversificação recente associaram-se às áreas abertas. Estes resultados indicam que áreas abertas atuam como um filtro filogenético de habitat para as espécies lenhosas florestais em todos os locais analisados, independentemente da escala e da composição de espécies de cada local. Os resultados sugerem que os clados de Rosanae e Asteranae estão na linha de frente do processo de expansão florestal sobre as áreas abertas, e o clado de Magnolianae restrito às áreas florestais. A busca por padrões gerais de organização das comunidades ecológicas a partir de sua estrutura filogenética parece consistir numa ferramenta útil para a exploração e entendimento sobre o funcionamento de sistemas ecológicos. Estas abordagens poderiam beneficiar estratégias de gerenciamento e conservação destes sistemas, por simplificarem sistemas ecológicos complexos e por mostrarem padrões gerais independentes da escala espacial analisada.

The search for consistent patterns in nature has been a major goal of ecologists. This study aimed to employ phylogenetic analyses to improve the understanding of an ecological process, the expansion of forest expansion over open areas. The use of evolutionary information considers species as not independent units in relation to each other, as they share their evolutionary history. Such hierarchical organization of species is very important to determine the rules governing assembly processes in local communities. Phylogenetic approaches were used to evaluate phylogenetic patterns…

Os padrões de associação entre epífitos e forófitos não podem ser considerados espécie-específicos, mas as árvores que os epífitos colonizam também não são um conjunto aleatório das espécies forofíticas de um determinado local. Ao invés disso, parece haver uma preferência de certos epífitos por diferentes forófitos. No entanto, se conhece pouco sobre os fatores que determinam essa preferência. Nosso objetivo nesse trabalho é avaliar como os atributos funcionais e a filogenia dos epífitos vasculares influenciam na associação dos epífitos com os forófitos em uma Floresta Ombrófila Mista no sul do Brasil. Para isso nós (1) investigamos padrões de associação positiva e negativa entre grupos funcionais de epífitos e grupos de forófitos e como a diversidade e os atributos funcionais dos epífitos variavam em função do tamanho do forófito e (2) inferimos sobre a existência de sinal filogenético no uso de árvores hospedeiras pelos epífitos, procuramos por estrutura filogenética nas comunidades epifíticas e investigamos diferenças de composição filogenética de epífitos vasculares em diferentes clados de forófitos. Foram amostrados 70 forófitos compreendendo 15 espécies pertencentes a diversos clados e com arquiteturas e características variadas. A amostragem compreendeu 31 espécies epifíticas com os principais clados sendo Polypodiaceae, Bromeliaceae e Orchidaceae. A associação de grupos de epífitos vasculares com diferentes grupos de forófitos sugere que as características dos forófitos proporcionam ambientes contrastantes e que diferentes valores de atributos são necessários para colonizar esses ambientes. Mais especificamente espécies epifíticas com menor área específica foliar (SLA) parecem predominar em árvores maiores e maior SLA em árvores menores. Encontramos sinal filogenético na utilização dos forófitos, sugerindo que a conservação das interações com os forófitos deve ter sido importante ao longo da evolução dos epífitos. A tendência a agrupamento filogenético nas comunidades epifíticas sugere a influência de filtros ambientais representados pelas diferentes características dos forófitos estruturando as assembleias de epífitos. Clados mais basais de forófitos apresentaram composição filogenética distinta devido, sobretudo, a presença de diferentes clados de monilófitos epifíticos nessas árvores. Angiospermas epifíticas ocorreram principalmente em forófitos pertencente as eurosídeas. A preferência de epífitos por forófitos parece ser influenciada pelo surgimento de novidades morfológicas e ecofisiológicas em alguns clados, enquanto outros mantiveram o seu nicho ancestral. A composição florística das florestas quando da origem dos clados epifíticos também parece influenciar a associação entre epífitos e forófitos. Ao utilizar informações sobre os atributos e filogenia das espécies de epífitos vasculares nós podemos melhor compreender os mecanismos ecológicos e históricos que influenciam os padrões de associação entre epífitos e forófitos.

▼ Biological diversity is threatened worldwide and it is a priority to generate more information that can be used both for understanding ecological processes and determining conservation strategies. For my dissertation, I focused on amphibian diversity patterns in lowland rainforests of southwestern Amazonia to evaluate the importance of habitat heterogeneity in the region. My main purpose was to test the hypothesis that amphibian communities in different forest types differ in species richness, composition, and abundance. I used standardized visual encounter surveys to quantify the species composition and abundance of amphibians at four sites, each containing four forest types (floodplain, terra firme, bamboo, and palm swamp). I used leaf-litter plots to evaluate the effect of soil and leaf-litter characteristics on species richness and abundance of leaf-litter frogs. I intensively sampled at one site and then sampled three other sites (distance among sites varied 3.5-105 km) to evaluate whether the patterns observed at one site were similar elsewhere. I also updated the information on threatened and potentially threatened amphibians in Peru and my study region. I found that no species appears to have experienced population declines in southeastern Peru, suggesting that the region still contains the original species pool. My results support the hypothesis that amphibian communities differ across forest types and that patterns observed at the local scale (one site) are similar at the regional scale (four sites). My data also indicate that there is no correlation between species composition and geographic distance among sites. Instead, an important proportion of the gamma diversity is represented by habitat-related beta diversity. My leaf-litter plot data showed that part of the variation in the leaf-litter community structure is explained by soil and litter characteristics. I found that soil total phosphorus and, to a lesser extent, humidity, leaf-litter mass, and pH is linked to species presence/absence and abundance. My study provides the first standardized, quantitative comparison of amphibian community structure across four major forest types in southwestern Amazonia and highlights the fact that forest types are complementary and necessary for maintaining high species richness in the region.

▼ Patterns of community structure may be examined using phylogenetic and morphological data; these patterns can then be used to infer the processes that gave rise to these patterns. Communities made up of similar species may be structured by habitat filtering, wherein only species with traits necessary to survive in a particular location are found there. Communities made up of dissimilar species may have been structured by competition, which reduces overlap in resource use. I examined the sensitivity of phylogenetic community structure (PCS) metrics to changes in phylogeny and community delimitation method, investigated patterns of PCS and correlation to environmental variables at multiple spatial and taxonomic scales, and assessed whether morphological data gave results similar to phylogenetic data using North American desert bats as a model system. I found that PCS metrics were robust to moderate changes to phylogeny and that these metrics also trend in the same direction regardless of delimitation method. Bat communities tended to be made up of species that were significantly more closely related than expected by chance, or phylogenetically clustered, at large spatial and taxonomic scales; this tendency towards clustering decreases with decreasing scale. Phylogenetically clustered communities also tended to occur in harsher environmental conditions than more overdispersed communities, or those made up of species not closely related. From a morphological perspective, communities were made up of species that were morphologically clustered or not significantly different from random. Morphological community structure was positively correlated with PCS, indicating that these different datasets gave similar results. These results indicate that North American desert bat communities are made up of phylogenetically and morphologically similar species and that environmental variables such as temperature and seasonality may influence community structure. This suggests that habitat filtering is playing a predominant role in structuring these communities.

▼ Phylogenetic Community Structure (PCS) metrics are becoming more common in community ecology. PCS metrics estimate the phylogenetic relatedness among members of an ecological community or assemblage. If ecological traits are conserved, then phylogenetic clustering (i.e., taxa are more closely related than expected by chance) indicates habitat filtering as the key process in community assembly. On the other hand, a pattern of phylogenetic overdispersion (i.e., taxa are more distantly related than expected by chance) suggests competition is dominant. Most studies to date have used PCS of unmanipulated ecosystems, but the value of PCS metrics will be best revealed in experiments. This project used PCS for aquatic beetle (Coleoptera) assemblages in experimentally manipulated seasonal wetlands on a cattle ranch in south-central Florida, and compared PCS metrics to standard ecological metrics. Wetlands were experimentally treated with all combinations of pasture management, fencing to exclude cattle, and controlled burning during 2006-2009. Beetle assemblages in fenced wetlands were significantly more overdispersed compared to non-fenced wetlands, suggesting that this treatment decreases habitat filtering, causing competition to become the dominant process in community formation. There was also a significant pasture x fence x burn interaction effect, with assemblages in wetlands differing in PCS depending on what combination of the three treatments were applied. Phylogenetic Diversity (PD – a measure of branch length of a community or assemblage on a phylogenetic tree) was highly correlated with genera richness (number of genera), and these metrics along with the expected number of genera (D – an ecological diversity index) found significant differences among burn treatments and a pasture x iii burn interaction. The results of this study indicate that PCS metrics complement classical ecological methods and should be widely applied. Advisors/Committee Members: Jenkins, David.

▼ Abstract : The patterns of niche occupancy within local communities, the spatial variability of biodiversity along environmental gradients of stress and disturbance, and the processes of plant succession are several fundamental topics in ecology. Recently, the trait-based approach has emerged as a promising way to understand the processes structuring plant communities and has even been proposed as a method to rebuild community ecology based on functional traits. Therefore, linking these fundamental themes through a functional lens should give us more insight into some basic questions in ecology and will be the main objective of my thesis. Generally, my PhD project is to investigate the structures of functional space occupancy along both spatial and temporal gradients. Specifically, the objective of Chapter 2 is to investigate the patterns of functional niche occupancy by calculating three key niche metrics (the total functional niche volume, the functional niche overlap and the average functional niche volume) from speciespoor communities to species-rich communities and to determine the main driver of the observed pattern of functional niche occupancy across plant communities worldwide. In Chapter 3, I aim to predict and explain the variation of species richness along gradients of stress and disturbance, by linking the dynamic equilibrium model and functional niche occupancy based on the framework developed in Chapter 2. The objective of Chapter 4 is to experimentally test the application of a globally calibrated CSR ordination method based on three leaf traits (leaf area, leaf dry matter content and specific leaf area) in local studies. Finally, the aim of Chapter 5 is to experimentally test the hypotheses reconciling the deterministic and historically contingent views of plant succession, by investigating the variation of taxonomic and functional dissimilarities between communities along gradients of stress and disturbance. The global study (Chapter 2) is based on a collection 21 trait datasets, spanning tropical to temperate biomes, and consisting of 313 plant communities representing different growth forms. The local studies (Chapter 3, 4 and 5) are based on the same experimental system consisting of 24 mesocosms experiencing different levels of stress and disturbance. The experiment started in 2009 with the same seed mixture of 30 herbaceous species broadcast over the 24 mesocosms and ended in 2016. We allowed natural colonization of seeds from the common soil seed bank and from the surroundings during the seven-year succession. Ten traits were measured on five individuals (sampled directly from the mesocosms) per species per mesocosms in 2014 (Chapter 3 and 4). Another set of traits (16 traits including some traits that were not able to measured directly in the mesocosms) were measured at the species level (species mean traits values) for the 34 most abundant species (some species disappeared in the mesocosms) over the seven years, by regrowing them separately for one growing season. In Chapter 2, we… Advisors/Committee Members: Shipley, John William (advisor).
