Can regional and local filters explain epiphytic bryophyte distributions in the Atlantic Forest of southeastern Brazil? Acta Botanica
Batista,Wanessa Vieira Silva Menezes; Santos,Nivea Dias dos.
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...

Distribution, ecology, and reproduction of bryophytes in a humid enclave in the semiarid region of northeastern Brazil Acta Botanica
Batista,Wanessa Vieira Silva Menezes; Pôrto,Kátia Cavalcanti; Santos,Nivea Dias dos.
ABSTRACT The ready availability of water resources distinguishes the humid forest of Chapada do Araripe, Ceará State, Brazil, from the semiarid vegetation around it. The regional climate demonstrates a marked seasonality of rainfall that affects the ecological strategies of the species found there. We studied the bryophytes of the humid forest of Chapada do Araripe, analyzing their diversity, geographic distributions, and ecological and reproductive aspects. Bryophytes were collected from different substrates using the random-walk method. We gathered information concerning the geographic distribution, functional groups (life forms, light tolerance guilds, and habits) and reproductive aspects of each taxon. We found 76 bryophyte species, predominantly...
