RESUMO
Na Reserva Florestal Walter Egler, localizada a 64 km de Manaus, no município de Rio Preto da Eva, foi investigada a ocorrência de Pteridófitas ao longo de uma toposseqüência. O grupo ocorre nos três ambientes observados na área (baixio, vertente e platô) com diferença tanto qualitativa quanto quantitativa. Foram registrados 375 indivíduos, distribuídos em oito famílias, 10 gêneros e 17 espécies; entre epífitas, hemiepífitas, herbáceas e arbóreas. Das 8 famílias, 4 ocorrem em todos os ambientes: Dennstaedtiaceae, Hymenophyllaceae, Dryopteridaceae e Lomariopsidaceae, enquanto, Cyatheaceae e Vittariaceae ocorrem apenas no baixio. Das 17 espécies encontradas, sete ocorrem apenas no baixio, três na vertente e cinco são comuns em todos os ambientes.
ABSTRACT
The occurrence of Pteridophytes was investigated along a transect at the Walter Egler Forest reserve, located 64 km from Manaus in the municipality of Rio Preto da Eva. The group occurs on the three landscapes observed in the area (lowland, slope and plateau) with a both qualitative and quantitative difference. Three hundred and seventy five (375) individuals were established, distributed in 8 families, 10 genera and 17 species; among epiphytes, hemepiphytes, herbaceous and arboreal. Of the 8 families, 4 occur on all landscapes: Dennstaedtiaceae, Hymenophyllaceae, Dryopteridaceae and Lomariopsidaceae, whereas, Cyatheaceae and Vittariaceae occur only on lowland. Of the 17 identified species, 7 occur only lowland, 3 on slope, and 5 are common on all landscapes.
