Levantamento da anurofauna em fragmento de floresta da área urbana do município de Boca do Acre – AM

Abstract

With population growth comes the increase in cities and the main consequences for this fact related to the ecological environment is the transformation of landscapes and functions to which was able to do. Thus, the non-conservation of urban forest fragments tend to suffer frequent human impacts that can end up impeding the biodiversity of these places. To the which the focus of this work is the anuran amphibians that are very sensitive to anthropic actions that are caused when changes in your environment, mainly related to pollution and climate change. Therefore, the objective of this work is to estimate the abundance of anuran species in an anthropized area in the municipality of Boca do Acre, Amazonas. Present the highest abundance of frog species and compare the abundance of urban frogs between the rainy and low-rain seasons. During the study, 99 individuals were observed, belonging to three families Leptodactylidae, Hylidae and Bufonidae. The families Hylidae and Leptodactylidae were more representative in the sampling, both with five registered species. Leptodactylidae (Adenomera andreae, Adenomera hylaedactyla, Leptodactylus sp., Leptodactylus petersii, Leptodactylus pentadactylus). Hylidae (Boana sp, Boana punctate, Dendropsophus leucophyllatus, Osteocephalus oophagus, Scinax ruber). While the Bufonidae presented only one species (Rhinella marina). Among the 11 species found, the buffoonid Rhinella marina proved to be the most abundant, with 58 individuals throughout the campaign. Only the species Dendropsophus leucophyllatus and Leptodactylus petersii had one individual collected during sampling and the months with The largest number of individuals registered were February and May, both with 20 individuals found. January and March were the other months with the highest abundance of frogs registered with 16 each, followed by the months of June with 15 and April with 12 individuals. Concluding that even in urban areas the rainy season still influences the abundance of individuals and species.
