Élıhely-értékelés állatközösségek diverzitása alapján a dél-mexikói Montebello-i Tavak Nemzeti Parkban
We evaluated the diversity of amphibians, reptiles and mammals in the Lagos de Montebello National Park, Chiapas, Mexico. The aim of this study was to compare the forested habitat types based on the ecological parameters of their vertebrate assemblages in order to suggest those habitats which could be considered as a priority for the local and regional biodiversity conservation. Field data was collected during 1997−1998, in four sampling sites using live capture techniques appropriate for each vertebrate group. In total, we registered 56 species: 10 amphibians, 18 reptiles and 28 mammals. Most of the diversity parameters calculated together for the three animal groups showed a clear tendency following the perturbation gradient of the habitats. However, calculating the parameters for each one of the groups, we could not find a common tendency; it was not possible to make a clear ranking between habitats. The gamma diversity of the area was relatively high while the similarity of the assemblages was very low with a high species turnover as well as a high habitat complementarity, suggesting that the Lagos de Montebello area has a high beta diversity value. According to these results using only local (α) diversity measurements is insufficient to rank habitats or sites for setting conservation priorities in the National Park and there is a need for an integrated strategy for both local and regional conservation planning.
