The distribution and composition of communities are influenced by
factors that determine the environmental characteristics in a particular
region. In order to obtain more information regarding the fauna of
frogs in the region of the Parnaíba River Delta, Northeastern Brazil, we
performed a quantitative ecological study to compare the composition
and distribution of the amphibian communities. The study was conducted
in the two largest islands of Deltafrom September 2008 to August 2009.
Fifteen ponds were selected and slowly covered in search of males in
calling activity. We recorded 21 frog species, distributed in five
families and 11 genera. Ilha Grande de Santa Isabel(21 spp.) had higher
species richness than the Ilha das Canárias (11 spp.). Although most
species are considered to be common in open areas, they were highly
influenced by the structural complexity of the vegetation. The highest
richness was observed in environments with greatest availability of
microhabitats for reproduction. The preservation of different
environments found in the two islands, associated with the maintenance
of suitable habitats for reproduction of each species, will contribute
to the conservation of amphibian communities of the Parnaiba Delta
River. Source the articles: Diversity and distribution of anuran in two islands of Parnaíba River Delta, Northeastern Brazil
