ISACCH, Juan Pablo et al. Diversidad de Tetrápodos en un mosaico de ambientes del sudeste de la ecorregión Pampeana como herramienta para planificar en conservación. Rev. Mus. Argent. Cienc. Nat. [online]. 2016, vol.18, n.2, pp.211-233. ISSN 1853-0400.

Despite advances in the understanding about the biodiversity in some regions, this is in general rather dispersed and has not been analyzed regarding their emergent properties and ordered in contexts to facilitate decision-making. The southeast of the Pampas shows an outstanding environmental diversity in a relatively restricted area, with a significant amount of information about biodiversity of Tetrapods. Our goal was to gather this information within a common framework, making a list of the relative abundance of species at each environment, highlighting species of conservation concern. We evaluated the complementarity among taxa (amphibians, reptiles, birds and mammals) in terms of composition, total number of species and number of threatened species. Our results on Tetrapods’ diversity data shows that this small area harbor a number of species representative of Buenos Aires Province, 12 species of amphibians, 26 reptiles, 233 birds and 34 species of mammals, of which 41 are threatened and two endemic. The environments represented (grassland, dunes, mountains, wetlands, estuaries, marine, agroecosystems and urbanizations) contribute differently to the overall diversity of Tetrapods. The uneven distribution of species richness, threatened species and composition within each taxon among environments and among taxa highlights the usefulness of this type of analysis in the elucidation of the spatial variation of biodiversity and it should assists in territorial planning within a framework that optimizes the conservation of biodiversity.
