Abstract

The didelphimorphs in Mexico are found all over the country except for the Baja California Peninsula. The aim of this study was to use 3 methods to assess the phylogenetic diversity of the species Marmosa mexicana, Tlacuatzin canescens, Caluromys derbianus, Chironectes minimus, Didelphis marsupialis, Didelphis virginiana, Metachirus nudicaudatus, and Philander opossum, and to determine the potential conservation areas for these mammals. Phylogenetic information was included to measure the taxonomic weighting, taxonomic dispersion, and taxonomic distinctness within the Mexican biogeographic provinces. In addition, a gap analysis was performed to show which protected areas contain the didelphimorphs listed under a conservation category. Considering phylogenetic diversity with the former analysis, results indicate that the biogeographic provinces most important for conservation of didelphimorphs are the Gulf of Mexico, the Pacific Coast, and Oaxaca, although Soconusco and Sierra Madre del Sur also have to be considered. We also observed that not all of the richest sites corresponded with current protected areas. This study is important because it employed different conservation approaches based on phylogenetic measures and was focused on Mexican marsupials, of which 1 species is endemic and 2 are of conservation concern.
