Abstract
Foi realizado o levantamento da brioflora de uma caatinga arbórea pertencente a Estação Experimental da Empresa Pernambucana de Pesquisas Agropecuárias (IPA), situada no município de Caruaru (8º08'00"-8º10'00"S, 36º02'00"-36º 10'00"W), Pernambuco. A área estudada compreende 20ha, tem altitude aproximada de 550m e médias anuais de precipitação e temperatura de 671 mm e 23ºC, respectivamente. As coletas foram realizadas durante as estações de estiagem (out-nov/1990) e chuvosa (mai-jun/1991), tendo sido investigados os seguintes substratos: solo, rocha, caules vivos e em decomposição. Registraram-se 16 espécies de briófitas, sendo 14 Bryopsida e 2 Hepaticopsida. Bryaceae e Fissidentaceae foram as famílias de maior representatividade específica na área. A maioria das coletas indicou a predominância de espécies terrícolas e saxícolas, seguindo-se as corticícolas e as epíxilas. O trabalho contém informações sobre distribuição geográfica e aspectos ecológicos das espécies.
A floristic survey of bryophyte was carried out in a experimental station at the Empresa Pernambucana de Pesquisa Agropecuária at Caruaru (Lat. 8º08'00"-8º10'00"S; Long. 36º02'00"-36º10,00"W), Pernambuco State. This area has 20ha, an altitude of 550m, an annual rainfall average of 671mm and 23ºC of temperature. The bryophytes were collected during the dry season (oct-nov/1990) and the rain season (may-jui/1991), on the following substrata: soil, rocks, living and dead trunks. There were identified 16 species, 14 Bryopsida and 2 Hepaticopsida. Bryaceae and Fissidentaceae were the most rich families in number of species. In the studied area, the terricolous species were predominant followed by saxicolous, corticolous and the species of decaying wood. Geographical distribution and ecological informations about the species were included.
