Intraspecic phenotypic dierentiation among geographically separated populations is common in anurans. We performed morphometric analyses of the endemic frog Hypsiboas cordobae in order to assess the geographic variation of morphometric variables along of distribution of the species. We measured 15 morphometric variables on 86 individuals from six localities of Córdoba and San Luís provinces. We found sexual dimorphism in ten variables. The comparative analysis showed signicant dierences between populations and discriminant analyses showed high percentages of classication (87,50%). Eight morphometric variables showed positive correlation with latitude; and ten variables showed positive correlation with altitude. However, the correlations between morphometric distances and latitudinal/altitudinal were not signicant. This geographic variation in the morphometry of the species may be due to environmental dierences, or may be due to the age of individuals. Therefore, these data could be supplemented by studies directly related to the environmental conditions of each locality, as well as skeleton-chronological study to determine individual age. 2013 artículo científico 1659-4266 https://www.redalyc.org/articulo.oa?id=515651978002 es http://www.redalyc.org/revista.oa?id=5156 UNED Research Journal / Cuadernos de Investigación UNED application/pdf Universidad Estatal a Distancia UNED Research Journal / Cuadernos de Investigación UNED (Costa Rica) Num.2 Vol.4 |
