▼ This dissertation describes the epiphyte communities on tall shrubs in forests of western Oregon, with a focus on potential effects of management practices on these communities. Shrubs and other hardwoods have recently gained recognition as hotspots of diversity for epiphytes in young conifer forests of the region. Yet little is known about how shrub epiphytes differ among stand types or in response to management. The first study presented here compares shrub epiphyte communities among unthinned young stands, thinned young stands and old growth in 17 areas within the Coast Range and Cascades. In young stands where shrub epiphytes are sparse, overstory thinning may have enhanced richness of lichens on shrubs and increased similarity of the communities with those in old stands. However, when thinning was associated with a decrease in the density of older shrub stems, bryophyte cover also decreased relative to unthinned stands. To gain perspective on shrub epiphyte diversity at the landscape level, I compared communities in our initial study sites with those in nearby putative "hotspots" of macrolichen diversity, located using stand structural features and topography (e.g. riparian areas and rocky outcrops). Hotspots had greater mean richness of both lichens and bryophytes on shrubs than other stand types, and a high number of uncommon species. Differences detected in bryophyte cover among stand types led me to develop and test transplant methods for comparing accumulation rates of mat-forming bryophytes among stands of different ages. Both Antitrichia curtipendula and Isothecium myosuroides grew as well, on average, in a young stand as in an old-growth stand, though they apparently died in a clear cut. This suggests that the distribution of these species may be limited more by dispersal or establishment than by an inherent inability to grow in young stands. I conclude that protecting a portion of the shrub stems during thinning and harvest operations should provide refugia and help minimize negative impacts of management on bryophytes and lichens associated with older shrub stems, as well as the overall epiphyte community. Local and regional diversity of shrub epiphytes may also benefit from identification and protection of landscape-level hotspots. Advisors/Committee Members: Muir, Patricia S.

▼ This thesis includes four separate studies. The first two studies assessed edge effects in a 700-year-old forest. After 20 years of exposure, epiphyte assemblages on the clearcut edge were similar to those of the forest interior, but there were some differences in vertical distribution patterns. Several species restricted to the upper canopy of the forest interior occurred farther down in the crowns of trees on the clearcut edge. Many species were associated with thick moss mats. Thalli of two cyanolichen species were reciprocally transplanted among four tree crowns. Lobaria oregana grew less on the clearcut edge than in the forest interior. Populations of Pseudocyphellaria rainierensis had acclimated to the edge environment. The third study evaluated whether these two species require old growth and/or thick, underlying moss mats to achieve normal rates of growth and mortality. Thalli were transplanted into tree crowns in 13 forest stands representing 4 age classes: old growth, mature, young, and recent clearcut. Wooden racks were used instead of trees in clearcuts. Half of the cyanolichen thalli were transplanted onto thick moss mats, half onto bare bark. Both species grew at least as well in the younger forests as they did in old growth, but growth rates were significantly lower in clearcuts. Mortality rates were very low in young, mature, and old-growth forests but high in clearcuts. P. rainierensis grew significantly better on moss than bare bark. The fourth study evaluated the long-term potential of live tree retention for cyanolichen conservation. Lichen litterfall was sampled in a natural, multiple-age stand containing remnant trees and regenerating forest. Two lichen species (L. oregana and Sphaerophorus globosus) were strongly associated with remnant trees. Biomass of both species was highest near remnant trees and was significantly higher within groves of remnant trees than at the edges of these groves or near isolated trees. Cyanolichen populations appear to have persisted on remnant trees since before the last fire. They are slowly recolonizing the regenerating forest. Retention of live trees, including hardwoods, combined with longer rotation periods, has great potential to maintain cyanolichens in managed forests.

▼ Bromeliaceae é uma família de angiospermas cuja distribuição é quase exclusivamente Neotropical. Cerca de metade das espécies conhecidas de bromélias são epífitas. No Brasil a maioria dos estudos sobre floração, sistema de reprodução e polinização com Bromeliaceae foi desenvolvido na Floresta Atlântica, seguidos por poucos registros para as formações de Caatinga, Cerrado, em vegetação de campo rupestre e floresta ombrófila mista. Estudos desta natureza são ainda mais escassos para vegetação chaquenha e os poucos dados conhecidos são oriundos do Chaco Argentino e para vegetação de Chaco brasileiro há apenas um. Em Tillandsioideae ocorrem alguns dos mais diversos gêneros de Bromeliaceae, como por exemplo, Tillandsia, cuja distribuição é a mais ampla da família. O gênero é constituído por ervas, epífitas ou rupícolas, de tamanho variável. Neste trabalho, apresentado em um capítulo que será submetido a revista Flora, foram investigados comparativamente a fenologia reprodutiva, a morfologia e a biologia floral, o sistema de reprodução, os visitantes florais e polinizadores de três espécies sintópicas de Tillandsia (T. duratti, T. loliacea, T. recurvifolia) em remanescente de vegetação chaquenha. As três espécies apresentaram diferença quanto ao padrão de floração e frutificação, à morfologia floral e não compartilharam visitantes florais e polinizadores, apresentando sobreposição de seus períodos de floração. A floração na estação seca pode ter sido ser responsável pela relação negativa das espécies com fotoperíodo. A relação positiva com a pluviosidade e a umidade relativa do ar entre T. duratii e T. recurvifolia, respectivamente, provavelmente ocorreu devido as datas médias destas ocorrerem nos meses de abril e junho, meses atípicos nos anos da amostragem, com altos índices de pluviosidade. Enquanto que em T. loliacea a pluviosidade de quase zero em julho possa ter contribuído com a relação negativa com a umidade relativa do ar. Frutificação sazonal e na estação seca foi registrada somente para T. recurvifolia, enquanto, as demais frutificam o ano todo e dispersam no período chuvoso. Este trabalho mostrou a ocorrência de polinização bimodal em T. duratii (mariposas não-esfingídeo e abelhas medio-grande porte) e T. recurvifolia (beija-flores e borboletas) e provável ocorrência de polinização generalista (entomófila) em T. loliacea. Somente T. recurvifolia é autoincompatível e depende de vetor de pólen/polinizador, enquanto as demais espécies são auto-compatíveis e autoférteis.

▼ This study fills a void in autecological research of D. antarctica by investigating the epiphytic relationships between the tree ferns and those vascular plant species which utilise its caudex. Research was based on hypotheses designed to explain aspects of the distribution of obligative epiphytes and the reliance of facultative epiphytes on D. antarctica caudices as well as why apogeotropic roots of terrestrially rooted specimens invade the tree fern‘s root mantle. Close to 1200 specimens of Soft Tree Fern (D. antarctica) were examined in 19 replicate field plots representative of temperate moist forests in north-eastern Tasmania. Dicksonia antarctica morphological and site floristics variables were recorded from each site. Selected parametric and non-parametric statistical tests were employed to analyse the relationships between and among the observed and recorded environmental, morphological, floristic, epiphytic and apogeotropic variables. Dicksonia antarctica frond plasticity was first examined because epiphytes are likely to be influenced both by site climatic conditions and by their host‘s architecture which in turn also influences microsite conditions. How frond size, frond frequency and frond shape change as D. antarctica grows older and taller was investigated using regression analysis. The inferred photosynthate store of D. antarctica was considered a critical determinant of emerging frond size and frequency. Frond size, frequency and shape were shown to vary with canopy closure, maximum temperature and site fertility. The relationships between caudex length and the size, frequency and shape of fronds are most likely indirect as a result of autocorrelation. The direct causal relationship is instead between the photosynthate store and frond size and frequency i.e. frond productivity. Two main epiphyte zones were identified on D. antarctica caudices (stems). These zones were largely delineated by surface microclimate, texture and substrate conditions. The first zone consists of the lower caudex nearest the ground and is dominated by obligate hygrophytic vascular epiphytes. The second zone is at the apex of the caudex, which is colonised by obligate epiphytes that can survive a drier more exposed microclimate compared to the lower caudex. In between the lower caudex and caudex apex zones is typically a length of caudex which is largely devoid of obligate epiphytes. Twenty-eight species of terrestrial flora were found to utilise large D. antarctica caudices as a regeneration substrate, providing strong evidence of the importance of D. antarctica caudices in maintaining floristic diversity in the closed-canopy wet forests of the region. Dicksonia antarctica caudices were identified as the dominant establishment substrate for Atherosperma moschatum, Pittosporum bicolor and Tasmannia lanceolata in these forests. Nothofagus cunninghamii can establish on all four substrates surveyed, provided there is sufficient insolation, but no single substrate dominates. Olearia argophylla seedlings were prolific across all…

Submitted in fulfillment for the Degree of Masters of Applied Sciences (Biotechnology), Durban University of Technology, Durban, South Africa, 2016.

Activated sludge (AS) flocs are paramount in biological treatment of wastewater, are comprised of microbial consortia with organic and inorganic material bound together by extra polymeric substances (EPS). The filamentous bacteria play a vital role in the floc formation process by providing the necessary structural support. Presence of epiphytic attachment on selected filamentous bacteria is a commonly occurring phenomenon in activated sludge samples. Different theories have been proposed to describe this phenomenon; however, not much research has been carried out to explore the profundity of the attachment. In this study, an attempt has been made to elucidate the intrinsic nature of the epiphytic attachment between the bacterial rods and filamentous bacteria based on microscopic (morphological and structural) analysis. Characterization of these epiphytes were performed using fluorescence in situ hybridization (FISH) at group level using Alpha, Beta and Gamma Proteo-bacterial probes. Morphological characteristics of filament hosts and the bacterial rods at the interface region was assessed using scanning electron microscopy (SEM). The SEM micrographs indicated that the attachment was facilitated by more than the EPS layer. Further ultrastructural examination using transmission electron microscopy (TEM) indicated a possible cell-to-cell interaction between epiphytes and the selected filaments. Fibrillar structures resembling amyloid-like proteins were observed within the filament cell targeted by the epiphytes. An interaction was apparent between the amyloid like proteins and the epiphytes as exhibited by the direction of fibrillar structures pointing towards the approaching epiphytes. Common bacterial appendages such as pili and fimbria were absent at the interface and further noted was the presence of cell membrane extensions on the epiphytic bacteria protruding towards the targeted filamentous cell. The sheath of host filaments however, remained intact and unpenetrated, during colonization. Amyloid-like fibrils at interface may potentially play the role of attachment sites for the attaching epiphytes, as attachment facilitating appendages were not visualized.

Este modo de vida possui algumas desvantagens para aquisição de nutrientes e água e por isso mostram-se demasiadamente sensíveis às variações ambientais da floresta. Tendo em vista este aspecto entre outros, foram analisadas a estrutura, composição e distribuição das epífitas vasculares em duas formações vegetais distintas (restinga e povoamento subespontâneo de Elaeis guineensis Jacq.) e além disso, foi realizado um levantamento florístico para toda área da Ilha. Em cada uma das unidades amostrais foram alocadas 50 parcelas de 100 m totalizando 1 ha ao todo. Em cada parcela foram contabilizadas as epífitas em forófitos com DAP ≥ 10 cm e os forófitos foram divididos em classes de altura. Na área da restinga foram encontradas 16 espécies pertencentes à 10 gêneros e 5 famílias, com quatro novas ocorrências. Já para a área do povoamento subespontâneo de Elaies guineensis (Arecaceae) foram encontradas 24 espécies, pertencentes a 22 gêneros e 15 famílias, com registro de cinco novas espécies para a Ilha. Para as duas áreas verificou-se baixa riqueza com quase ausência da família Orchidaceae, considerada uma das mais abundantes entre as epífitas. Em geral, não houve padrões definidos entre a distribuição ao longo das classes de altura do forófito. As variáveis morfométricas testadas através de regressão linear simples indicaram que em geral o tamanho do forófito influencia diretamente a riqueza e abundância das epífitas. A distribuição horizontal foi analisada através do índice de Morisita indicando que a maioria das espécies apresenta uma distribuição agregada, assim como dispersão anemocórica foi a mais recorrente entre as espécies. Quanto à florística de epífitas da Ilha da Marambaia, foram listadas 93 espécies, 53 gêneros e 21 famílias, indicando que a baixa riqueza pode estar ligada ao fato da Ilha da marambaia ser uma região com baixa taxa de pluviosidade.

▼ Placophora binderi can be described as an "obligate epiphyte" as it does not respond well to any culture conditions and is found growing only on other algae in the natural environment. This habit may have arisen as a response to the best available substrate in a harsh environment (Harlin 1971; Moss 1982). Any nutrient transfer which may occur between Placophora binderi and its basiphyte, usually various species of Codium, is probably by diffusion as rhizoids do not penetrate the basiphyte cells but simply lie between the Codium utricles providing better anchorage. A triphasic life history exists with isomorphic gametophyte, carposporophyte and tetrasporophyte generations. The male and female gametophytes are dioecious. This study confirms Scagel's (1953) observations for the development of the juvenile, mature and reproductive thallus. The juvenile develops as an erect polysiphonous thallus which produces a prostrate lobe as an adventitious branch from the basal segments. This prostrate lobe develops into the dorsiventrally flattened mature thallus. Reproductive structures are produced on erect branches which are initiated at the mature thallus margins. The gametophyte develops on evanescent trichoblasts produced on erect reproductive branches while the tetra sporophyte develops within these erect branches. The female gametophyte has a four-celled carpogonial branch with an auxiliary cell forming after fertilisation from the supporting cell. At the electron microscope level several vesicle types were seen in the reproductive organs. In the male, spermatial vesicles are produced which probably aid in release of the spermatia (Kugrens 1980). These are also visible under the light microscope. In carposporogenesis and tetrasporogenesis, three vesicle types are produced. Striated vesicles appear for a short while during the early stages and probably function as protein stores. Fibrillar vesicles are large and visible under the light microscope. These probably act as carbohydrate storage organelles (Triemer and Vasconcelos 1979; Kugrens and West 1973c; Tripodi 1971). Cored vesicles appear late in sporogenesis and probably aid in adhesion once the spores have settled (Chamberlain and Evans 1973; Wetherbee 1978). Carpospores follow the "serial release" type pattern observed in Polysiphonia (Boney 1978). Tetraspores are released singly via a rupture in the tetrasporangial wall as in Ceramium rubrum (Chamberlain and Evans 1973). Both carpospores and tetraspores germinate in the typical bi-polar Ceramium-type pattern described by Dixon (1973)

▼ Epiphytes, plants which grow on other plants for support yet are not parasitic to their host, are a prominent feature in Australia’s rainforest. Despite this, very few epiphyte studies have been undertaken in Australia. This thesis examines the distribution of vascular and non-vascular epiphytes over two spatial scales, within the host tree and across elevation, and examines how gradients of light and moisture affect these distributions. This study focuses on the two epiphyte ‘hotspots’ in Australia, the tropical rainforests in the Wet Tropics Region (Far North Queensland) and the subtropical ‘Gondwana Rainforests’ (northern New South Wales). This thesis explores how the distribution patterns found in these two Australian ecosystems compares to those found for rainforest elsewhere in the world, with special reference to epiphyte distributions over continuous light and moisture gradients and broader zonation systems. Very little research examines the distributions of both moss and vascular epiphytes within the same study. In the subtropical site, vascular epiphytes and mosses were recorded from four height zones across five elevations between 300 and 1100 m above sea level (asl). Vascular epiphyte species richness was highest in the inner canopy (6.3 species), while mosses tended to have a uniform distribution over the height zones (3.8 - 5.0 species). Both moss and vascular epiphyte species richness peaked at mid-elevations (500 - 700 m), with moss richness peaking at a slightly higher elevation than the vascular epiphytes. Host tree characteristics (bark roughness, host size) explained very little of the species composition or richness of epiphytes. The strong patterns found in the species richness and composition of epiphytes over host tree and elevation gradients suggest that moisture, temperature and light may be one of the major influences on epiphyte distributions in this ecosystem. Moving beyond broad zonation systems, in the tropical rainforest site, the distribution of vascular epiphytes was examined over continuous gradients of light and humidity, using individual environmental measurements for each epiphyte surveyed. There was a strong partitioning of taxonomic groups over the light and vapour pressure deficit (VPD) gradient. Orchids had the highest average total transmitted light levels and VPD (27% and 0.43 KPa, respectively), followed by theferns (21% and 0.28 KPa) and then the other angiosperms (17% and 0.2 KPa). There was also strong partitioning of species within taxonomic groups, suggesting that microclimatic factors play an important role in the realized niche spaces of epiphytes within the tropical Australian rainforest. Epiphytes show a strong distribution of drought mitigating traits within the host tree, but few studies have examined distribution patterns of these traits over elevation gradients. We assessed whether epiphyte species that occupy comparable realised niche spaces within host tree and landscape scale gradients have similarities in taxonomy, morphology or physiology in the…

Um estudo foi realizado sobre a família Bromeliaceae na região nordeste do estado do Paraná (Brasil) (23°-24,5° S e 49,5°-51,5° W), prioritariamente coberta por Floresta Estacional Semidecidual. O objetivo foi conhecer a riqueza da família, além de atualizar a distribuição geográfica das espécies da região e reconhecer características morfológicas importantes, através de chaves de identificações e descrições. O trabalho foi realizado através de coletas em 35 municípios para análise de plantas vivas e ampliação de material herborizado depositado em herbário, além da consulta aos acervos de herbários paranaenses. Esta família está representada na região por 35 espécies, pertencentes aos gêneros Tillandsia (11), Dyckia (oito), Billbergia (cinco), Aechmea e Vriesea (três), Acanthostachys, Ananas, Bromelia Canistrum e Pitcairnia (uma espécie cada), que se distinguem pelos tipos de hábito (epífitas ou rupículas), folhas (margem inteira ou espinescente, formando roseta ou não), características da inflorescência (simples ou composta, pedunculada ou séssil), sépalas (livres ou fundidas, simétricas ou assimétricas), e presença ou não de apêndices petalinos, pelo tipo de fruto (baga, cápsula ou infrutescência) e semente (comosa ou não). Foram propostas chaves para identificação de gêneros e espécies, além de descrições e ilustrações. Do total, 16 espécies não estão protegidas em Unidades de Conservação do Paraná, três espécies de Dyckia são citadas apenas para o estado do Paraná, sendo duas destas registradas em apenas uma localidade.

This study presents one survey about Bromeliaceae family occurring in the Northeast Paraná State (Brazil) (23°-24,5° S e 49,5°-51,5° W), mainly occupied by Seasonal Semidecidual Forest. The objective was to find the family diversity, and to update the geographical distribution of species in these region and recognize important morphological features, using in identification keys and descriptions. Field trips were performed to 35 municipalities for fresh material observations and collecting herbarium specimens, and also through analysis of Paraná State Herbaria specimens. The family is represented by 35 species, included in Tillandsia (eleven), Dyckia (eight), Billbergia (five), Aechmea and Vriesea (three), Acanthostachys, Ananas, Bromelia, Canistrum, Pitcairnia (one species each), that can be differentiated one each other by fruit type (baccate, capsule or infrutescence) and seed (appendaged or naked), inflorescence morphology (simple or compound, scape evident or lacking), sepals (free or not, symmetrical or assymetrical), and leaf (forming a vase or not, with margin entire or spinescent), petals (appendaged or not) and habit (epiphytes or lithophytes). Were included keys to identify genera and species, descriptions and illustrations. Of the total, 16 species are not protected by Paraná State Conservation Units, and three Dyckia species are endemic to the Paraná State, and two species are only known by one locality collection.

▼ Field and culture studies have been carried out with the epiphytic red alga, Ceramium codicola J. Agardh, with the objective of determining what factors in its biology cause it to be limited to growth on one host plant, Codium fragile (Suringar) Hariot. A survey of epiphytes of C. fragile and C. setcheIIii confirm the absence of C. codicoIa on C. setcheIIii and shows that C. codicola is the most abundant epiphyte on C. fragiIe. More species of epiphytes were present in wave sheltered areas. C. codicoIa was not present in samples from the Strait of Georgia. In culture, C. codicoIa grew to reproductive maturity apart from C. fragiIe from spores, but the life history was not completed. The presence of living or extracted C. fragiIe or C. setcheIIii did not promote germination, growth or reproduction of C. codicola, and typically inhibited it. C. codicoIa did not grow well at temperatures above 15°C in culture; C. fragiIe, Ceramium pacificum and C. gardner i grew weII at 10-18°C. Rhizoids of C. codicola have bulbous tips, which appears to be genetically determined. Substratum can affect later development of these rhizoids, which may obscure the bulbous nature of the rhizoid tips. C. codicoIa is unable to produce digitate holdfasts on its rhizoid tips, as was observed in other Ceramium spp. , and may only be able to attach by entangling its rhizoids in loosely constructed substrata such as Codium spp. C. setcheIIii is not suitable because it is too compact, and penetration of rhizoids is inhibited. Field studies show that C. codicoIa is reproductive throughout the year, although reduced in the winter. Thallus length was also reduced in the winter. In addition, thalIi were longer in wave sheltered sites, and longer in the upper regions of their intertidal distribution. Male and female gametophytes and tetrasporophytes of C. codicola exhibit a hetermorphism in branching pattern. Gametophytes differ from tetrasporophytes by having more primary branches and larger angles of branching. Females differ from males by having a higher degree of proliferous branching, resulting in a higher number of primary branches and a higher branching ratio. Branching pattern in females may be the result of continued growth of involucral ramuli, and it may optimize reproductive potential.

▼ The canopy of trees has been an unreachable portion for scientific exploration until few decades ago, and the wonders and enigmas that the treetops enclose are increasingly unfolding. This study investigated the canopy environment and its epiphytes on the formation of canopy soil, transfers of biomass and N to the ground and decomposition processes in relation to climatic variables in a coastal temperate rainforest in the Queets River watershed, Olympic National Park, Washington. Canopy soils developed in bigleaf maple (Acer macrophyllum Pursh) and Sitka spruce (Picea sitchensis Bong. Carriere) canopies were studied. Canopy soils developed in bigleaf maple were classified as Typic Haplohemist, whereas Sitka spruce canopy soil was classified as Typic Haplosaprist. Bigleaf maple canopy soils are dominated by hemic horizons, have lower bulk density and C/N ratio relative to Sitka spruce canopy soils, which have lower pH, N content, CEC and extractable N. Relative to the forest floor, canopy soils have lower total C and N content, however canopy soils in this ecosystem are enhancing the pool of C and N by 20% and 25%, respectively, relative to the C and N pools of the forest floor. Annual litter inputs under bigleaf maple were 4700 kg ha^-1 with the biggest biomass contribution from maple leaves. Epiphytic litterfall contributed with 550 kg ha^-1 of the total litter inputs. This is nearly 12% of total annual litter input, the highest contribution of epiphytic litterfall registered. Carbon and nitrogen returns in litter were dominated by maple; epiphytic litterfall contributed 240 kg ha^-1 yr^-1 of C and 5.7 kg ha^-1 yr^-1 of N to the forest floor. In Pacific Northwest forest productivity is often limited by N availability, and high inputs of N from leaves and epiphytes under the canopy of big leaf maple could make this tree a hotspot of N in this old-growth ecosystem. Decomposition rates of green and senescent bigleaf maple leaves were determined in the bigleaf maple canopy and on the forest floor beneath maples. Decomposition rates of canopy and forest floor Oi horizons were also determined on the forest floor. Decomposition rates after two years ranged from 0.15 yr^-1 (for canopy Oi) to 0.58 yr^-1 (for green maples leaves). Soil temperatures had seasonal variation and were not significantly different between the canopy and forest floor. Moisture content was significantly lower in the canopy soils compared with soils on the ground. Despite significant differences on the moisture regime between the canopy and forest floor, there was no significant difference in decomposition rates between the canopy and forest floor. Wet/dry cycles of canopy soils and potential activity of soil organisms (that live in canopy soils) might have influenced decomposition aboveground. Decomposition rates for this study were strongly correlated to N concentration of the substrate. The… Advisors/Committee Members: Zabowski, Darlene (advisor).

▼ Epiphytic bacterial communities on the surfaces of marine algae are poorly characterised. Most information available on marine bacterial epiphytes is derived from culture-based studies. With the rapid development of molecular community analysis technologies, it is now possible to obtain a more comprehensive picture of marine microbial populations on living surfaces. The intertidal macroalga Ulva australis, belongs to the cosmopolitan groupof green marine algae (Ulvales) known to require the presence of bacteria for normal growth and has been suggested to employ specific bacteria for the defence against fouling by micro- and macro-organisms. This thesis has examined the composition and structure of the surface associated bacterial community on Ulva australis using 16S rRNA gene clone library, denaturing gradient gel electrophoresis (DGGE), and catalysed reporter deposition– fluorescence in situ hybridisation (CARD-FISH) analysis. The 16S rRNA gene clone library revealed that the five main bacterial groups present in thesurface associated community were Bacteriodetes, Planctomycetes, Alpha-, Gamma-, and Delta-Proteobacteria. Twenty-two sequence phylotypes were identified, suggesting that the epiphytic community was of relatively low diversity. A clone similar to an algal morphogenesis inducing Cytophaga strain was identified, indicating that U. australis harbours bacteria important for thallus structural maintenance. DGGE analysis showed that while the bacterial community varied over spatial and temporal (seasons) scales it also included a stable subpopulation consistently associated with the seaweed surface. Sequencing of selected DGGE bands suggested that members of the Alphaproteobacteria and the Bacteriodetes belonged to the stable subpopulation. Using CARD-FISH with different phylogenetic probes demonstrated that Alphaproteobacteria (~ 70%) and Cytophaga-Flavobacteria (~13%) constituted the majority of bacterial cells on the surface of U. australis. A comparison of the results provided by the molecular community analysis methods, employed in this thesis, and those of culturing of epiphytic bacteria from U. australis revealed that each approach provides different patterns of phylogeny and extent of diversity. For example, the culture collection and the clone library detected a relatively highamount of Gammaproteobacteria, however, DGGE and CARD-FISH did not. Also, low species diversity clone sequences and isolates of Alphaproteobacteria contrasted with the high numbers detected by the DGGE analysis. In addition to the phylogentic determination of the epiphytic bacterial community, CARDFISH was also used to assess the organisation and distribution of bacterial cells across different zonal regions on seaweed surface. It was found that approximately 40% of bacterial cells clustered in aggregates, or microcolonies. These aggregations were considered to be heterogeneous in composition and were mainly comprised of multiplyspecies. The occurrence of more non-viable solitary single rather than aggregated cells…

O enriquecimento com diferentes formas de vida, como com epífitas, é fundamental para o desenvolvimento de florestas em restauração, em paisagens fragmentadas, onde a dispersão natural é limitada. Epífitas são plantas que crescem sobre outras (forófitos). Têm papel ecológico importante, realizando ciclagem de nutrientes e oferecendo microambientes e alimentos a outras formas de vida. Características de forófitos, clima e microclima influenciam populações locais de epífitas. Para aumentar o sucesso do enriquecimento em florestas em restauração, é importante determinar quais filtros podem atuar no processo. Fizemos o censo de áreas que receberam autorização para supressão vegetal e obtivemos que, a cada ano, cerca de 500 ha de Florestas Estacional Semidecidual e Ombrófila Densa, em diferentes estágios de regeneração, são desmatados, apenas no estado de São Paulo. Elas podem fornecer material que pode ser recuperado e empregado na restauração de outras florestas. Neste trabalho, damos enfoque às epífitas que podem ser disponibilizadas a partir desse desmatamento. Transferimos 360 indivíduos de seis espécies delas, entre Bromeliaceae (Aechmea bromeliifolia e Tillandsia pohliana), Orchidaceae (Catasetum fimbriatum e Rodriguezia decora) e Cactaceae (Lepismium cruciforme e Rhipsalis floccosa) para duas Florestas Estacionais Semideciduais em processo de restauração, uma com 13 anos e outra com 23. As médias anuais de cobertura de dossel, entre os forófitos escolhidos, variaram entre 62,2 e 85,0% na floresta de 13 anos e entre 79,3 e 92,9% na floresta de 23 anos. Taxas de sobrevivência das diferentes espécies de epífitas foram superiores em floresta mais jovem, variando de 63.33 a 100%, enquanto em floresta mais madura variaram entre 55,17 e 89,66%. Transplantes usando fibra de palmeiras, capaz de reter água, e realizados no início de estação chuvosa podem ter explicado o maior sucesso em floresta mais nova. Taxas de sobrevivência, fixação, ramificação, floração e frutificação não estiveram relacionadas à espécie de forófito, à rugosidade de casca ou à posição de transplante. Por outro lado, elas estiveram relacionadas às espécies das próprias epífitas. Apenas em algumas situações e para determinadas espécies, taxas de fixação, ramificação e reprodução sexuada estiveram relacionadas aos valores de cobertura de dossel. Animais podem ter importantes papéis como polinizadores e dispersores de epífitas, o que mostra que sua presença na floresta é fundamental para a permanência dessas plantas em longo prazo. Ao final, separamos as principais conclusões tiradas deste trabalho e fizemos um guia de procedimentos práticos a serem adotados no enriquecimento de florestas em restauração usando epífitas provenientes de florestas a serem suprimidas.

Enrichment using non-arboreal life forms, such as epiphytes, is critical to the development of forests under restoration, in fragmented landscapes, where natural dispersal is scarce. Epiphytes are plants that grow on top of other plants (phorophytes). They play very important ecological…

Entre os vegetais existem duas estratégias distintas para superar as condições de estresse hídrico que condicionam a sensibilidade a dessecação (SD) que está associada a mecanismos de evitação e a tolerância a dessecação (TD) que envolve suportar o estresse hídrico diretamente no nível dos tecidos e no nível subcelular. Sabe-se que os custos acoplados aos mecanismos de dessecação e reidratação em espécies TD são elevados, e provavelmente superiores aos de espécies SD. Desta forma, a coexistência de espécies com estas estratégias, como ocorre no ambiente epifítico da Cidade Universitária Armando Sales de Oliveira (CUASO), induzem questões quanto a as vantagens relativas de espécies TD sobre SD. Devido aos altos custos da estratégia TD é possível propor que estas deveriam apresentar um ganho médio de carbono superior a de espécies SD durante o período favorável (com disponibilidade hídrica). Além disso, também é razoável esperar que as distintas formas de uso da água, vinculadas às estratégias, poderiam facilitar o convívio de espécies TD e SD através da segregação de nichos. Com intuito de verificar essas hipóteses, foram realizadas análises relacionadas a estrutura de comunidade de epífitas da CUASO e, a partir destas, a detecção da associação espacial mais freqüente, que resultou composta por Pleopeltis hirsutissima (TD) e Microgramma squamulosa (SD). Estas espécies foram então selecionadas para avaliar parâmetros associados à dinâmica do uso da água, assimilação líquida de carbono, dinâmica da capacidade de uso da luz, estado de hidratação foliar e pigmentos fotossintéticos. Os resultados apontaram que espécies de ambas as estratégias não apresentam sinais de estresse crônico no ambiente estudado. Os dados reforçaram as respostas contrastantes de TD e SD, refletindo as formas distintas de lidar com os recursos e condições do ambiente. Ao contrário do esperado, P. hirsutissima não apresentou uma assimilação de carbono superior a M. squamulosa, indicando que o ganho de carbono não é um dos fatores possíveis na compensação dos custos acoplados a sua estratégia (TD). Porém, os resultados apresentados quanto a dinâmica da capacidade de uso da luz sugerem que a coexistência é facilitada pela segregação de nichos de luz, sendo a espécie TD mais heliófila do que a espécie SD

In land plants the resistance to drought can be accomplished by two main strategies. One involves mainly dehydration avoidance mechanisms and the other is based on the ability to withstand drought at the tissues and down to subcellular levels. The former is found on the desiccation sensitive plants (DS) and the last describes the desiccation tolerant plants (DT). The metabolic costs of the desiccation tolerance mechanisms are probably high, at least when considering the cessation of photosynthesis during anabiosis - a condition that is absent in drought avoidance strategies. The coexistence of drought avoiders and desiccation tolerant plants in the same substrate and condition can rise some questions about the relative advantages of each strategy…

Olive anthracnose is an important fruit disease in olive crop worldwide and no effective method is currently available for their control. Fruit-associated microorganisms may be explored for designing new strategies for the biological control of this disease. The main aim of this work was to assess the diversity of fungal endophytes and epiphytes inhabiting olive fruits of two cultivars with different susceptibilities to olive anthracnose, and select the strains with the greatest antagonistic effect against Colletotrichum acutatum, the main causal agent of this disease. Culture-dependent method was used to assess fungal diversity in olives from cvs. Madural (susceptible) and Verdeal Transmontana (moderately tolerant), and the isolates obtained were identified for molecular identificantion using internal transcribed spacer (ITS1, 5.8, ITS2) region of the rDNA. The in vitro effect of the isolates against C. acutatum was analysed by the dual-culture method. Results revealed that only endophytic fungal communities composition differ significantly between cultivars. Cultivar Madural was distinguished by the higher abundance of Gibberella spp. whereas cv. Verdeal Transmontana was characterized by the exclusive occurrence of Neofabraea vagabunda. Although epiphytic community of both cultivars overlapped, several fungal genera preferred either olives from cv. Madural (e.g. Chaetomium) or from cv. Verdeal Transmontana (e.g. Cytospora, Epicoccum and Quambalaria). All the seven fungal tested were able to inhibited C. acutatum growth (inhibition coefficients up to 30.9), and caused morphological changes in its hyphae. Some fungi also inhibited significantly C. acutatum sporulation (from 46-86%) and germination (from 21-74%). Altogether, the results offer new insights into plant-microbe-microbe interactions and highlighted the potential use of these antagonistic fungi in the biocontrol of olive anthracnose.

A antracnose da oliveira é uma doença com grande importância a nível mundial, e não existe nenhum método eficaz para o seu controle. Os microrganismos existentes nas azeitonas podem ser explorados na tentativa de encontrar novas estratégias de luta biológica contra esta doença. Este trabalho teve como objetivo avaliar a diversidade de fungos endofíticos e epifiticos existentes nas azeitonas de duas cultivares com diferentes suscetibilidades à antracnose, e selecionar os isolados que apresentam maior atividade antagonista contra o Colletotrichum acutatum, principal agente causal desta doença. A diversidade de fungos nas azeitonas das cultivares Madural (suscetível) e Verdeal Transmontana (moderadamente tolerante) foi avaliada através da obtenção de isolados em meio de cultura, seguida pela sua identificação molecular através da sequenciação da região ITS (ITS1, 5.8S, ITS2) do rDNA. A atividade antagonista dos isolados contra C. acutatum foi avaliada usando o método de co-cultura. Os resultados obtidos evidenciaram que apenas a composição da comunidade de fungos endofíticos diferiu significativamente entre as cultivares. A cv.…

▼ As epífitas vasculares podem ocupar locais variados ao longo do fuste e nas copas das árvores, ficando expostas a diferentes condições de intensidade luminosa, nos diversos estratos do dossel florestal. Estudos sobre preferências das epífitas, por diferentes estratos do dossel, têm sido realizados, mas, os dados são escassos no que se refere à anatomia foliar e aspectos ecofisiológicos destas espécies. O hábito epifítico envolve várias estratégias adaptativas em resposta aos diversos estresses a que estas plantas estão expostas, especialmente aos estresses hídrico e nutricional, e muitos deles são evidenciados em suas folhas. O estudo foi realizado em um remanescente de Mata Atlântica, na Trilha do Muriqui, Parque Estadual da Serra do Brigadeiro, Araponga, MG. Objetivou-se identificar as espécies de epífitas em 10 forófitos, verificar as possíveis relações entre as características do forófito (rugosidade do súber, altura) e a comunidade de epífitas nele instalada, bem como caracterizar a anatomia foliar de todas as espécies e analisar a micromorfometria foliar em indivíduos da mesma espécie ao longo da estratificação vertical. Foram selecionados 10 forófitos com circunferência à altura do peito superior a 50 cm e que continham a maior quantidade de epífitas. O material botânico fértil, dos forófitos e das epífitas, foi depositado no Herbário VIC. Medições de luz foram realizadas por meio de um sensor quântico e medições de temperatura, umidade relativa do ar, altitude, taxa de evaporação e velocidade do vento foram realizadas com o aparelho Kestrel. Por meio de observações em campo e da análise de fotos digitais do tronco de cada forófito foi classificada a rugosidade do súber. Foram selecionadas amostras de 0,5 cm2 da região apical, mediana e basal de folhas expandidas; para avaliação anatômica o material foi processado e corado, conforme metodologia específica para montagem de lâminas permanentes. Foram realizados cortes transversais e longitudinais, diafanizações e dissociações epidérmicas em 23 espécies de epífitas, além de testes histoquímicos, para algumas espécies. Para a micromorfometria foliar de sete xiv espécies, que estavam presentes ao longo da estratificação vertical, foi utilizado o software Anati Quanti. A digitalização das imagens foi realizada em fotomicroscópio. As avaliações micromorfológicas foram feitas na região mediana de folhas expandidas. Foram encontradas 25 espécies de epífitas vasculares, distribuídas em 17 gêneros e 9 famílias, predominando as monilófitas. Os forófitos foram distribuídos em 8 espécies, 8 gêneros e 6 famílias. Não houve uma especificidade epífita-forófito, no entanto, algumas espécies são mais restritas a locais extremamente sombreados e Vriesea heterostachys foi a espécie generalista, sendo encontrada em todos os forófitos, ao longo da estratificação vertical. A maioria das espécies apresentou epiderme uniestratificada e apenas as espécies de Peperomia apresentaram epiderme multiestratificada. A presença de hipoderme aquífera foi evidenciada nas espécies de Bromeliaceae… Advisors/Committee Members: Wagner Campos Otoni, Aristéa Alves Azevedo, Luzimar Campos da Silva, João Augusto Alves Meira Neto, Rogério Ferreira Ribas.

Dados e análises de gradientes altitudinais em diversidade têm sido fundamentais para o desenvolvimento e avaliação de uma série de teorias gerais da biodiversidade. Esta proposta pretende contribuir para uma melhor compreensão dos padrões de diversidade das samambaias e licófitas ao longo de um gradiente de altitude no Sul do Brasil, abrangendo desde as formações florestais da planície, composta pela floresta de Terras Baixas, Submontana, como por formações florestais de altitude superiores, florestas Montana e Altomontana, e considerando a influência de fatores climáticos e de solo sobre as comunidades de plantas deste grupo. Assim, os objetivos deste estudo são: 1) verificar se a composição e riqueza de espécies varia ao longo do gradiente altitudinal; 2) se caso afirmativo, descrever em qual altitude podemos encontrar a maior diversidade; 3) analisar se existem diferenças ao longo do gradiente nos padrões de distribuição entre comunidade epifítica, terrícola e rupícola; 4) estabelecer quais são os fatores ambientais e de espaço que governam a distribuição das espécies de samambaias e licófitas, sua riqueza e sua cobertura na floresta brasileira ao sul do Atlântico; 5) investigar se espécies epifíticas e terrestres respondem igualmente aos condutores ambientais. Os resultados de um estudo detalhado, bem como de análises morfológicas, ecológicas, pedológicas e geográficas são: 1) a composição e riqueza de espécies variou significativamente ao longo do gradiente altitudinal; 2) riqueza e diversidade foram maiores nas formações superiores (Montana e Altomontana); 3) comunidades ecológicas distintas (epifítica, terrícola e rupícola) diferiram quanto ao padrão de distribuição observado ao longo do gradiente; 4) os fatores ambientais (tais como: insolação solar, precipitação, velocidade do vento, umidade relativa do ar relacionados ao clima e, concentração de matéria orgânica, alumínio, pH e profundidade, relacionados ao solo) apresentam maior importância na variação da distribuição de espécies ao longo do gradiente; 5) a variação da distribuição de espécies epífitas demostrou ser mais relacionada aos condutores ambientais relacionados aos fatores climáticos enquanto que as espécies terrestres, aos fatores edáficos. Processos de nicho (teoria de nicho) são os responsáveis por modular a distribuição e a abundância das espécies de samambaias e licófitas ao longo do gradiente altitudinal da Floresta Atlântica Sul Brasileira. Adicionalmente, é descrito novo registro de Stigmatopteris no Estado do Rio Grande do Sul, Brasil.

▼ Human modification of the abiotic environment can cause profound change to biological communities, yet many ecosystems that face intensive anthropogenic pressure can persist without undergoing major change. To understand the inherent stability of many systems facing human driven environmental change, we need an account of the mechanisms that allow ecosystems to withstand such change. Whilst it is well known that resource enhancement favours the growth of subordinate or weedy species over habitat-forming perennials, less is known about the inherent ability of herbivores to counter this increased growth. Throughout this thesis, I assessed whether such resource enhancement can encourage herbivores to compensate for the additional productivity of opportunistic algae that can cause the decline of seagrass habitats and the displacement of kelp forests. Human activities can modify resource availability on local (e.g. nutrients) through to global scales (e.g. carbon dioxide). Anthropogenically derived nutrients can increase local resource availability in coastal zones, stimulating the overgrowth of seagrass by epiphytic algae, leading to the decline of seagrass habitats. By experimentally manipulating nutrient concentrations and herbivore abundance, I showed that herbivores are capable of reducing the effects of local nutrient addition in a seagrass ecosystem by consuming the increased production of epiphytic algae. Importantly, this work showed that although nutrient addition increased food availability, herbivore abundance did not increase in the grazed treatments, suggesting that the greater consumption of algae was due to an increase in per capita grazing and not grazer abundance. Concurrent with the local enrichment of nutrients is the global accumulation of carbon dioxide (CO₂), which can act as a resource for photosynthetic organisms that are carbon limited. Indeed, I found that experimental enrichment of both nutrients and CO₂ proved to have a greater influence on the expansion of algal turf than the provision of either resource alone, but only in the absence of herbivores. Elevated nutrients and CO₂ increased herbivore consumption, which was proportional to an increase in herbivore metabolism. Where resource enhancement is ongoing, however, the influence of such change can overwhelm countering forces (such as herbivory) to the extent that the production of opportunistic algae escapes regulation and perennial species may be lost (e.g. seagrass decline on urbanised coasts). As the global loss of seagrass continues, efforts are made to restore lost meadows with the principle aim of restoring ecosystem function (e.g. faunal recolonisation). I used experimental restoration plots of known ages (1, 3 and 5 years) to test the rate of recovery of epifaunal composition and seagrass structure to that in an adjacent natural seagrass meadow. I found that whilst seagrass structure and epifaunal composition took three years to become similar to the natural meadow, epifaunal richness and abundance took one year. These results have… Advisors/Committee Members: Connell, Sean Duncan (advisor), Russell, Bayden D. (advisor), Tanner, Jason (advisor), School of Biological Sciences (school).

▼ Little is known about the composition of tropical epiphytic communities and the influence of environmental variables on community composition. In this thesis I quantify the diversity and biomass of bromeliads, and other vascular epiphytes along an altitudinal transect on the eastern slope of the southeast Peruvian Andes and then look for species’ adaptations related to patterns of diversity and biomass. I compare patterns with those of woody species. Bromeliad species, like tree species, were found to form ecological zones related to climate. The lowest altitude ecological zone (below 1250 m) is the lowland rainforest (LRF), which has the warmest climate and highest evapotranspiration. In LRF vascular epiphytes are less prominent than other ecological zones, with the lowest bromeliad species richness and lowest vascular epiphyte biomass. However, low water-availability gives rise to most variable shoot morphology of bromeliads. The tropical montane forest (TMF), between 1250 m and 2250 m, is intermediate in climate between the LRF and the tropical montane cloud forest (TCF). The TMF has the highest α-diversity, but species richness is lower than the TCF. The shoot morphology of bromeliads is intermediate between TCF and LRF. The highest altitude ecological zone with forest is the TCF (above 2250 m). The TCF has the highest bromeliad species richness, and lowest diversity of shoot forms. The low diversity of shoot forms represents the need for a large phytotelm (water-impounding shoot) to intercept and store precipitation. The TCF has the highest vascular epiphyte biomass, although the biomass is variable as a consequence of the natural disturbance caused by landslides. Along the transect bromeliad species with CAM photosynthesis are only present in the LRF. Terrestrial bromeliad distribution records covering the Neotropics show CAM photosynthesis is more prevalent in drier environments showing that CAM photosynthesis is primarily an adaptation to drought.
