Biogeografía de los anfibios anuros de la región central de la República Argentina
The distribution of sixty anuran taxa in central Argentina (28°- 36°S, 60°-68°W) is analyzed, as well as its correspondence with natural environments, taking into account phytogeographic formations, geomorphology, climatologic zones and zoogeographic regions. An isoline map of anurans diversity was...

| Resumo: | The distribution of sixty anuran taxa in central Argentina (28°- 36°S, 60°-68°W) is analyzed, as well as its correspondence with natural environments, taking into account phytogeographic formations, geomorphology, climatologic zones and zoogeographic regions. An isoline map of anurans diversity was constructed. High diversity occurs in the central-east zone of the study area, coincidently with plain environments and heterogenous phytogeographic formations; low values are found in homogenous phytogeographic formations. A dendrogram was obtained following UPGMA procedure, distinguishing 6 groups of phytogeographic associations based on amphibian distributions. A correspondence between natural environments and anurans presence is reported. |
