Abstract(s)
A rã verde ibérica, Pelophylax perezi, foi introduzida nos Açores e dispersou para todas as ilhas do arquipélago. Contudo, os únicos dados publicados sobre a espécie dizem respeito à sua presença e distribuição em grande escala. Este estudo pretende investigar a variabilidade morfológica de P. perezi em São Jorge, a partir de seis populações amostradas em diferentes locais da ilha. Os indivíduos foram identificados em função do género e medidos em relação ao peso corporal e comprimento. Neste artigo, apresentam-se dados preliminares sobre parâmetros morfológicos da espécie e estabelece-se a relação peso-comprimento. A análise de regressão mostra-se fortemente descriptiva. Mais investigação será necessária para melhor entender o significado dos coeficientes da recta de regressão para a espécie, nos Açores.
ABSTRACT: The Iberian green frog, Pelophylax perezi, was introduced in the Azores and widespread in all the islands of the archipelago. However, the only published data about the species concerns its presence and large-scale distribution. This study aims to investigate the morphological variability of P. perezi in São Jorge, from six populations sampled at different sites of the island. Individuals were identified for gender and measured for body mass weight and snout-vent length. In this paper, preliminary data on morphological parameters of the species are presented and it is established the weight-SVL relationship. The regression analysis shows to be strongly descriptive. More research is needed to better understand the real mean of coefficients in the regression line for this species in the Azores.
