Resumo: | ABSTRACT Environmental conditions in distinct tropical rainforest phytophysiognomies can act as regional filters in determining the distribution of montane bryoflora likewise, local filters inherent to phorophyte species can have modulating influences. We analyzed the bryophyte communities in three phytophysiognomies of Atlantic Forest, in order to examine the influences of local (phorophyte species) and regional (forest phytophysiognomies) filters on their distributions. The study was undertaken in the Serra do Mar State Park, Ubatuba, SP, Brazil, using 1 ha plots in three forest phytophysiognomies along an elevational gradient. Four phorophyte species were selected, with three to seven replicates each. The line-intercept method was used on each phorophyte for collecting botanical material. Multivariate analyses were used to correlate species distributions with environmental filters. A total of 71 taxa were identified. Mean bryophyte coverage did not vary among the different phytophysiognomies, and although their species compositions were markedly distinct, no cohesive or isolated groups were found. Among the local filters examined, phorophyte DBH was found to be correlated with bryophyte coverage; the pH of the bark of Euterpe edulis and the high rugosity of the trunk of the Cyatheaceae influenced species compositions. Other filters not evaluated here may also be relevant for determining species distributions. |

ABSTRACT Environmental conditions in distinct tropical rainforest phytophysiognomies can act as regional filters in determining the distribution of montane bryoflora likewise, local filters inherent to phorophyte species can have modulating influences. We analyzed the bryophyte communities in three phytophysiognomies of Atlantic Forest, in order to examine the influences of local (phorophyte species) and regional (forest phytophysiognomies) filters on their distributions. The study was undertaken in the Serra do Mar State Park, Ubatuba, SP, Brazil, using 1 ha plots in three forest phytophysiognomies along an elevational gradient. Four phorophyte species were selected, with three to seven replicates each. The line-intercept method was used on each phorophyte for collecting botanical material. Multivariate analyses were used to correlate species distributions with environmental filters. A total of 71 taxa were identified. Mean bryophyte coverage did not vary among the different phytophysiognomies, and although their species compositions were markedly distinct, no cohesive or isolated groups were found. Among the local filters examined, phorophyte DBH was found to be correlated with bryophyte coverage; the pH of the bark of Euterpe edulis and the high rugosity of the trunk of the Cyatheaceae influenced species compositions. Other filters not evaluated here may also be relevant for determining species distributions. |
