Species richness, relative abundance, and habitat of reproduction of terrestrial frogs in the Triângulo Mineiro region, Cerrado biome, southeastern Brazil

Based on field observations and pitfall sampling, we determined the species richness, relative abundance, and reproductive habitat of terrestrial frogs in three municipalities in the Triângulo Mineiro region, south Cerrado biome, in southeastern Brazil.

We found thirty-two species of terrestrial frogs, belonging to the families Brachycephalidae, Bufonidae, Cycloramphidae, Dendrobatidae, Leiuperidae, Leptodactylidae and Microhylidae. Most of the species were found in open areas and reproduced in human-generated environments, such as artificial lakes (10 species) and ponds (14 species). Dominance was high, with Physalaemus cuvieri Fitzinger, 1826 (Leiuperidae) representing 48% of sampled frogs. A larger number of individuals was captured in the wet season, when most of the species were reproducing. Compared to other areas of Cerrado biome, the Triângulo Mineiro sites presented a larger number of species, which may be attributed to the larger sampled area and greater sampling effort, lower altitude and presence of human generated habitats. The richness of terrestrial frogs was also larger than that in some forested localities in southeastern Brazil, indicating that the number of species cannot be explained only by precipitation and type of vegetation cover. The greater abundance of individuals during the wet season may be related to a greater movement of adults to breeding sites and to juvenile recruitment/dispersion. The heterogeneity of environments in the Cerrado biome, including its several isolated highlands, contributes to its high (local and regional) diversity of frogs. Neste estudo foram determinados a riqueza, abundância relativa e hábitat de reprodução de anuros terrestres em três municípios do Triângulo Mineiro, sul do Bioma Cerrado, sudeste do Brasil, baseados em observações de campo e armadilhas de interceptação e queda. Foram encontradas 32 espécies pertencentes às famílias Brachycephalidae, Bufonidae, Cycloramphidae, Dendrobatidae, Leiuperidae, Leptodactylidae e Microhylidae. Muitas dessas espécies foram encontradas em áreas abertas e se reproduziram em ambientes artificiais gerados por ação antrópica, tais como lagos (10 espécies) e poças (14 espécies). Physalaemus cuvieri Fitzinger, 1826 (Leiuperidae) foi a espécie dominante, representando 48% do total amostrado. Um grande número de indivíduos de diferentes espécies foi capturado na estação chuvosa, quando muitas das espécies estavam reproduzindo. As áreas amostradas na região do Triângulo Mineiro apresentaram um maior número de espécies quando comparadas com outras áreas do bioma Cerrado, o que pode ser atribuído à maior área amostrada, ao maior esforço de coleta, baixa altitude e presença de hábitats gerados por ação antrópica. A riqueza de anuros terrestres também foi maior do que àquela encontrada em localidades florestadas no sudeste do Brasil, indicando que o número de espécies não pode ser explicado somente pela precipitação e tipo de cobertura vegetal da área. A grande abundância de indivíduos durante a estação chuvosa pode estar relacionada ao maior movimento de adultos para hábitats de reprodução e ao recrutamento e dispersão de juvenis. A heterogeneidade dos ambientes no bioma Cerrado, incluindo algumas de suas áreas com maiores altitudes, contribui para a alta diversidade (local e regional) de espécies de anuros. 2017-12-07T04:49:22Z 2017-12-07T04:49:22Z 2008 Artigo Iheringia, Sér.
