Anurans have been suffering strong anthropogenic pressure and consequent population
decline, which highlights the importance of studies that elucidate distribution patterns of
species, and can be used to support in decision making for conservation of this group. In this
study, we investigated spatial variation in richness, composition, and distribution of anuran
species in a 25 km2 of Amazonian forest in the Maracá Ecological Station. The study was
conducted in a standard sampling grid of the Research Program in Biodiversity (PPBio), of
the Ministry of Science and Technology of Brazil. Twenty five riparian and 24 non-riparian
were sampled three times during two rainy seasons. Species composition was significantly
related to altitude. The riparian plots harbored higher species richness and different species
composition of anurans than non-riparian plots. Within the riparian zone, species composition
was related to stream width. Beyond the difference in species composition between riparian
and non-riparian areas, also we found greater abundance and richness of frog species in
riparian areas, that emphasizes the importance of water bodies, and their respective riparian
areas to conserve the diversity of frogs in Amazonian rainforests. |
