Conservação de anfíbios anuros endêmicos e ameaçados da Mata Atlântica setentrional

Abstract

The decline in amphibian populations is been recorded all around the world. Brazil has an important role in its conservation, since it has the greatest diversity of the group. The Atlantic Forest is the Brazilian biome that comprises the higher diversity and endemism of amphibians, however it is also the habitat of almost all endangered frogs. The northern portion of the biome is known as the Biogeographic Sub-region (BSR) Pernambuco, which includes the forest fragments of the north of the São Francisco River, except for the " Brejos de altitude". This region contains a very specific fauna and an unique genetic diversity, but only 1% of its remains are protected in the form of conservation areas. Conservation actions are urgently needed, however the lack of information is an obstacle for developing action plans in the region. In this context, in the first chapter, na macroecological approach was applied for the conservation of endemic and threatened frogs in the Northern Atlantic Forest. Thus, ten endemic species and one endangered were registered in the study area. The results suggest that the forest fragments found in the north of the state of Alagoas and in the southern state of Pernambuco, Brazil, are extremely important for maintaining the biodiversity, even in the face of climate change. The second chapter presents the description of the reproductive biology of the only endangered species the BSR Pernambuco, Agalychnis granulosa.
