The Atlantic Forest in southern Bahia State, Brazil, has high levels of diversity and vascular plant endemism. There have been few floristic surveys of the mountain forests there, however, especially those focusing on herbs and canopy plants, with studies of Atlantic Forest epiphytes having been limited to the southern and southeastern region of that country. The present study therefore surveyed the epiphytic angiosperms in the Serra das Lontras National Park (SLNP), the distribution of their species among genera and families, and their biogeographical patterns. Fieldwork was performed between February 2011 and March 2012. Collections were made along roads and trails and phorophytes were occasionally climbed and fallen trees and branches examined in order to sample canopy species. The study site demonstrated high epiphyte richness (256 spp.), one of the highest recorded in the Atlantic Forest. The richest families are Orchidaceae, Bromeliaceae, and Araceae, reaffirming the patterns reported in previous major reviews on epiphytes. The species exhibit high degrees of endemism (45%) to the Atlantic Forest, especially among the Bromeliaceae and Orchidaceae. One new occurrence to Brazil, four to the Atlantic Forest and 30 to Bahia state are registered. The SLNP shares more species with areas of southern and southeastern Brazil than with other northeastern states.

No entanto, poucos levantamentos florísticos foram realizados em á reas de floresta montana, especialmente para ervas e plantas de dossel. Estudos com epífitas estã o concentrados principalmente em á reas do Sul e Sudeste do Brasil. Desta forma, o presente estudo realizou o levantamento das angiospermas epífitas do Parque Nacional da Serra das Lontras (PNSL) e verificou a distribuiçã o das espécies pelas famílias e gêneros e seus padrõ es biogeográ ficos. As coletas foram realizadas entre fevereiro de 2011 e março de 2012 nas trilhas e estradas de acesso. Alguns foró fitos foram escalados e á rvores e ramos caídos foram examinados com o intuito de coletar espécies restritas ao dossel. A á rea de estudo apresentou alta diversidade de epífitas (256 spp.), uma das maiores já registradas para a Floresta Atlâ ntica. As famílias com maior riqueza sã o Orchidaceae, Bromeliaceae e Araceae, reafirmando os padrõ es encontrados anteriormente em revisõ es do tema. As espécies apresentam alto grau de endemismo (45%) à Floresta Atlâ ntica, especialmente em Bromeliaceae e Orchidaceae. São registradas uma nova ocorrência para o Brasil, quatro para a Floresta Atlâ ntica e 30 para a Bahia. O PNSL possui mais espécies em comum com o Sul e o Sudeste do que com a regiã o Nordeste.

“…The increase in turbulence within the canopy, is likely to increase efficiency of both cloud water capture by vegetation (Asbury et al, 1994;Cavelier et al, 1997;Clark et al, 1998c;Sugden, 1981), and downward flow of moisture. The high surface roughness is likely to considerably increase the radiation receipt of the forest by exposing a greater surface area of vegetation (Grubb and Whitmore, 1967).…”

A total of 190 holoepiphytic and 5 hemiepiphytic vascular plant species were collected from the canopy and the trunk of an emergent Ficus L. species host that is common to a Peruvian cloud forest. One hundred and fourteen of the vascular epiphyte species were orchids. A large majority of the vascular species were rare in occurrence. Vascular epiphyte diversity and density was highest in the outer canopy zone of the host crown. In the inner canopy zone there was a dearth of epiphytes, attributed to a high rate of epiphyte slumping on the smooth-barked branches. The trunk had a different suit of species to those found in the canopy.During the wet season, the thickening of epiphytic matter in the outer canopy zone appeared to contribute to a large amelioration of daytime and nocturnal temperatures through evaporation and heat retention respectively.Nocturnal temperatures were highest in the outer canopy zone, and were lowest on the forest floor. The latter was attributed to the downward flow of the product of radiative cooling as a result of the heterogeneous canopy on the steep slope.Epiphyte clumps appear to slump before competition causes the loss of early successional species. Some species showed a preference for more shaded epiphyte clumps and many were more frequent on smaller branch diameters. Most species showed a moderately high niche overlap with a large number of other species, which suggested a high degree of species coexistence.Epiphyte slumping is suggested to be the major driving mechanism for the maintenance of non-equilibrium in the community. Aspects of the phenologies of epiphytes, age-structure of the community and high environmental variation could be other mechanisms for the maintenance of a high degree of species coexistence.iii

“…A preferência pela copa é fenômeno consagrado para a flora epifítica, tendo sido registrada para a maioria dos trabalhos publicados no Brasil (WAECHTER, 1992;KERSTEN;SILVA, 2001;GONÇALVES;WAECHTER, 2002;GIONGO;WAECHTER, 2004), assim como no exterior (JOHANSSON, 1974;SUGDEN;ROBINS, 1979;INGRAM;NADKARNI, 1993;FREIBERG, 1996). Nieder et al (2001) afirmaram, quanto à ocorrência de epífitas em zonas do forófito, que próximo à superfície externa das copas é observada uma zona relativamente pobre em epífitas, seguida por uma zona intermediária bastante rica e da copa interna com significativa presença de pteridófitas.…”

ResumoCom o intuito de avaliar o grau de conservação das florestas ribeirinhas da bacia do rio Iguaçu no Primeiro Planalto Paranaense, foi realizado o levantamento qualitativo de epífitas vasculares em oito estações de Floresta Ombrófila Mista nesse planalto, seis localizadas em planícies aluviais e duas em encostas. Para o levantamento quantitativo, foram consideradas duas seres, inicial e média, com 50 forófitos levantados em cada uma. Foi utilizada divisão da árvore em 'zonas ecológicas' e atribuição de notas relativas à abundância das espécies nesses intervalos. O valor de importância foi calculado sobre a frequência nos forófitos e a dominância. Foram observadas 114 espécies (duas exóticas) de epífitas vasculares distribuídas em 52 gêneros e 20 famílias. A riqueza florística nos sítios variou de 29 a 83 espécies. Duas espécies dominam o ambiente, Microgramma squamulosa e Pleopeltis pleopeltifolia, com valor de importância bem superior ao das demais. As florestas em estágio inicial de sucessão apresentaram menor riqueza florística e diversidade ecológica que as em estágio médio. O número de espécies sobre forófitos variou de dois a dezessete. Foram estabelecidos três grupos sucessionais de espécies epífitas: pioneiras, secundárias e avançadas. As florestas foram consideradas fortemente perturbadas. As estações de floresta de encosta foram mais ricas que as de planície, estando, aparentemente, mais conservadas. As estações mais ricas são também as florestas mais desenvolvidas e menos visitadas pela população, indicando que a manutenção de indivíduos arbóreos ajuda a manter a diversidade e a abundância da flora epífita.

Abstract Forest conservation on the Iguaçu river basin, Paraná -evaluation of the vascular epiphyte community in different seres.Aiming analyze the conservation of the riverside forest on the Iguaçu river basin Eigth areas (six on floodplains and two on hillsides) were surveyed for the vascular epiphyte checklist. On the floodplains sites 100 trees were selected for the structural survey on two succession stages (initial and medium). The trees were divided into three zones. Dominance was estimated in each zone by scores for each species. The importance index was calculated from the frequency on the trees and the dominance. We found 114 species (two aliens) on 52 genera and 20 families. On the sites we found from 29 to 83 species. Most of the species were chacteristic holoepiphytes (89%). Microgramma squamulosa and Pleopeltis pleopeltifolia were the most important species. On the host trees epiphyte species number varied from two to 17. The forest considered to be initial succession presented lower species and ecological diversity than the forests considered medium succession. Three successional categories were established (early, intermediate and late succession species). All the forests were considered highly disturbed. The hillside forests were more species-diverse than the floodplain and apparently are better...
