This project will generate information about vertebrate and invertebrate assemblages of different ecoregions of Central Argentina, providing key features for the understanding of the trophic structure of the region's biological communities and species dynamics. The project focuses on the integration of biodiversity information, strengthening the Program of Biodiversity Research (PPBio) in Argentina. This is of special value in protected areas such as National Parks (two parks involved in this study: Sierra de las Quijadas and Talampaya National Parks), and other protected areas, one Provincial Reserve, Quebrada de las Higueritas, three private reserves: Piedra del Agua (La Carolina, San Luis), El Corralito (Luján, San Luis), Peyyta Karanday (San Francisco, San Luis) and one private property in Villa Mercedes.

This variety of preservation statuses and managing conditions will contribute directly to the evaluation of fauna biodiversity with a regional perspective, allowing the interpretation of the effects of numerous factors including land use, land cover and climatic variables on biodiversity patterns. The integrated perspective gives the advantage of direct comparison of biodiversity data from different groups, including arthropods, mammals and birds. Therefore, we can monitor differential effects of the factors on different faunal groups, evaluate sensitivity levels and general aspects. This all serves to promote informed management decisions and global interpretation of ecological systems.
