Title A name given to the resource Edge effects on fern community in an Atlantic Forest remnant of Rio Formoso, PE, Brazil Efeitos de borda na comunidade de samambaias em um remanescente de Floresta Atlântica de Rio Formoso, PE, Brasil Creator An entity primarily responsible for making the resource IAA Silva, AFN Pereira, ICL Barros Description An account of the resource We have investigated how edge effects influence the fern community of Jaguarão Forest (08º 35' 49' S and 35º 15' 39' W), located in the district of Rio Formoso, Pernambuco, Brazil. A comparative analysis was made of the interior and edge of the fragment of forest, regarding the richness, abundance and diversity of ferns in the two areas. Six plots of 10 × 20 m were chosen, three in each area. A total of 381 ferns were recorded, which were distributed among 25 species, 17 genera and 12 families. The two areas (edge and interior) were found to differ, with distinct relative air humidities and temperatures (p = 0.00254 and p = 0.00019, respectively). The interior showed higher diversity (t = 7.251 and p = 0.018) and richness (t = 6.379 and p = 0.023) than the edge area, but the same abundance (t = 1.728; p = 0.226) as the edge. Regarding the composition of the flora, it was clear that the interior is a habitat completely distinct from the edge with regard to the fern community, given that only one species, Adiantum petiolatum Desv., was common to both environments. It was concluded that the edge effect causes a decrease in richness and abundance of the fern species found in Jaguarão Forest, where the more sensitive species are being replaced by species that are tolerant to the disturbance caused by the creation of an edge.Este trabalho verificou como os efeitos de borda influenciam as comunidades de pteridófitas presentes na Mata do Jaguarão (08º 35' 49' S e 35º 15' 39' W), município de Rio Formoso, Pernambuco. O estudo foi feito através de análise comparativa entre os ambientes de interior e de borda. Para verificar a riqueza, abundância e diversidade das pteridófitas nos dois ambientes, foram estabelecidas seis parcelas de 10 × 20 m (200 m²), sendo três para cada ambiente. Foram contabilizados 381 indivíduos de pteridófitas, distribuídos em 25 espécies, 17 gêneros e 12 famílias. Os dois ambientes (interior e borda) caracterizaram-se diferentes entre si, com umidade relativa do ar e temperatura distintas (p = 0,00254 e p = 0,00019, respectivamente). O ambiente de interior apresentou maior diversidade (t = 7,251 e p = 0,018) e riqueza (t = 6,379 e p = 0,023) que o ambiente de borda, de acordo com o teste estatístico empregado (teste t pareado). A abundância, por outro lado, foi a mesma em interiores e bordas do fragmento (t = 1,728 e p = 0,226). Quanto à composição florística, ficou claro que o interior do fragmento estudado constitui um ambiente totalmente distinto da borda, no que se refere à comunidade pteridofítica, com apenas uma espécie comum aos dois ambientes, Adiantum petiolatum Desv. Assim, o presente estudo constatou que o efeito de borda causa diminuição na riqueza e abundancia das espécies de pteridófitas ocorrentes na Mata do Jaguarão, com a existência de substituição das espécies mais sensíveis pelas espécies tolerantes aos impactos causados por esse efeito.
