INFLUÊNCIA DA URBANIZAÇÃO NA MORFOLOGIA E CANTO DE Dendropsophus cruzi: UMA AVALIAÇÃO EM PARQUES URBANOS NO CERRADO GOIANO

Abstract

The high human population density is directly linked with direct and indirect effects on biota. The habitat transformation process affects different organisms, including amphibians. So the objective of the present work was to evaluate the effects of urbanization on the morphometry and song of a species of Dendropsophus cruzi in the Brazilian Cerrado. For this, we compared biological and environmental parameters of D. cruzi from two urban parks (in Goiânia) with animals from a rural area considered as a reference in the municipality of Santa Rosa Goiás. The animals in the urban park showed shorter rostro-cloacal length and shorter interval and call duration, compared to animals in the reference area. Besides that, urban environments showed higher temperatures, lower humidity and higher noise levels, variables that may be related to the differences in biological parameters found. Thus, the present work confirms the evidence of negative effects of urbanization in anurans of urban parks and can contribute to the creation and maintenance of parks that aim to conserve biodiversity.
