Actualización de la riqueza mastofaunística de Michoacán

Abstract

Updating information on the status of mammal fauna is fundamental for biodiversity conservation, given that mammals are indicators of environmental quality and functional integrity of ecological communities. Although studies and mammal collecting in Michoacán date back to 1892, by the year 2000 the structure of mammal communities was still unknown at regional as well as state level. Sampling efforts were carried out historically in the Trans-Mexican volcanic belt region, and were based on the study of Rodentia and Chiroptera. In the latest years, multiple studies have suggested taxonomic changes that modify taxonomic richness, requiring the updating of the taxonomic composition of mammal faunas for Michoacán. In this analysis, we estimate the presence of 9 Orders, 24 families, 95 genera and 170 terrestrial mammal species, corresponding to approximately 32% of the country's mammal species, standing out among the six states with higher species richness. In the state there are 30 species listed in risk categories, six endangered.
