2. Host tree bark traits and development of reintroduced Cattleya intermedia (Orchidaceae) plants in Southern Brazil
Resumo As características das cascas de árvores hospedeiras podem influenciar na distribuição e no desenvolvimento de epífitos. Amostras de casca foram suspensas em 10 e 20 mL de água destilada por 1, 4 e 24 h, para avaliação de métodos para a determinação do pH. Cascas de Myrcia brasiliensis, M. glabra e Myrsine coriacea hospedeiras de Cattleya i

3. Epiphyte-phorophyte relationships: assessing the differences between Seasonal Semideciduous and Swamp Forests in Southeastern Brazil1
RESUMO As epífitas vasculares são responsáveis por uma parcela considerável da biodiversidade tropical; no entanto, suas relações com os forófitos entre diferentes tipos de vegetação em que ocorrem ainda são pouco compreendidas. Neste trabalho, objetivamos avaliar a presença, a abundância, a distribuição vertical e a categoria ecológica (holoe

4. Vascular epiphyte biomass in a South Brazilian fragment of Atlantic Forest
Abstract The present study aimed at sampling the biomass of vascular epiphytes within a protected area in South Brazilian Atlantic Forest. All tree specimens with diameter at breast height equal or greater than 4.8 cm were measured and divided into classes. In each class, 10% of tree specimens were randomly selected for epiphytic biomass measuring. Furthermo

5. Composition, diversity and structure of vascular epiphytes in two contrasting Central Amazonian floodplain ecosystems
ABSTRACT Research focusing on assemblages of vascular epiphytes in the Amazon are scarce. This is especially true for Amazonian floodplain forests, for which only two previous studies have been published. We compared composition, richness and structure of epiphyte assemblages in white-water and black-water floodplains (várzea and igapó) in Central Amazonia

6. Vascular epiphytes in the Grumari restinga, RJ: floristic and similarities between restingas in Eastern Brazil
Resumo A comunidade de epífitas vasculares ocorrente na restinga de Grumari, estado do Rio de Janeiro, foi avaliada através de coletas realizadas no ano de 2014 e complementadas com materiais de herbários e publicações. 37 espécies de epífitas vasculares foram registradas, distribuídas em 21 gêneros e seis famílias. As famílias mais ricas são Orc

7. Vascular epiphytes on Pseudobombax (Malvaceae) in rocky outcrops (inselbergs) in Brazilian Atlantic Rainforest: basis for conservation of a threatened ecosystem
Resumo Este estudo avaliou a riqueza de epífitas vasculares sobre Pseudobombax sp. nov. em três inselbergs do Domínio Atlântico no estado do Espírito Santo e avaliou a similaridade florística entre as áreas. Foram amostrados 111 forófitos, em três regiões no sul do estado do Espírito Santo e identificados 151 espécies, 77 gêneros e 21 famílias

8. Vascular epiphytic flora of a high montane environment of Brazilian Atlantic Forest: composition and floristic relationships with other ombrophilous forests
ABSTRACT Only a few studies regarding vascular epiphytes have been conducted in mixed ombrophilous forests (MOF) in Serra da Mantiqueira, a mountainous environment in the Brazilian Atlantic Forest, where the relationships of epiphytic flora with other physiognomies are unknown. This study aimed to survey the epiphytes of a MOF remnant located in Serra da Man

9. Edge effect on vascular epiphytic composition in a fragment of Atlantic Forest in northeastern Brazil
Epiphytes are common in the canopy of temperate and tropical forests, where they substantially contribute to species diversity and to key ecosystem processes. However, little is known about the effects caused by deforestation on this group of species, especially in northeastern Brazil, an area experiencing intense anthropogenic pressure. This study aimed to

10. Floristic composition and spatial distribution of vascular epiphytes in the restingas of Maracanã, Brazil
Vascular epiphytes constitute a life form that is important to maintaining the biological diversity of forest ecosystems, because they provide food resources and specialized microenvironments for fauna in the forest canopy. This study aimed to describe the floristic composition and ecological aspects of vascular epiphytes occurring in the restingas (coastal

11. Edge effect on vascular epiphytes in a subtropical Atlantic Forest
Forest fragmentation affects biological communities by reducing habitat and increasing edges, thus reducing the effective size of the habitable zones. The subtropical atlantic Araucaria forest, typical on the southern Brazil, in some regions has been reduced to less than 1% of its original size lasting only in small isolated fragments. This study aimed to an

12. Structure and Composition of vascular epiphytes in a two vegetation formations in Ilha da Marambaia Mangaratiba, RJ / Estrutura e Composição de epífitas vasculares em duas formações vegetais na Ilha da Marambaia Mangaratiba, RJ
The vascular epiphytes belong to a guild that occupies other plants (usually arboreous species) as support for fixing without parasiting them. This way of life have some disadvantages for the nutrients and water acquisition and therefore showed itself excessively sensitive to environmental variations in the forest. Having in view this aspect among others, th
