Resumen:

Deforestation is one of the main factors negatively affecting the conservation of biological diversity. We assess the impact of deforestation on biodiversity in Mexico by quantifying its effect on (1) mammal species' distributions, (2) delineation of biogeographical regionalization, (3) the effectiveness of conservation area networks to prevent biologically deleterious land use/land cover change, and (4) area prioritization for biodiversity conservation. Deforestation has a significant impact on species' distributions with habitat loss ranging from 10-90%, leading in some cases to high risks of extinction. Significant changes also occur in the delineation of biogeographical provinces (bioregionalization) due to deforestation because several areas with unique fauna show high rates of natural habitat reduction, leading to potential ecological and biogeographical changes in species interactions and distributions. A variety of decreed natural protected areas now show increasing pressures due to potential land use conversion from natural habitat to agriculture and urban settlements which threatens their biodiversity content. Area prioritization for biodiversity conservation is seriously negatively affected by deforestation because a significantly increased total area is required to conserve endemic mammals as compared to what would have been adequate 30 years ago before significant loss of forest cover. These trends urge immediate collaborative actions between academic, governmental, and NGO sectors to prevent and reduce further deforestation nationwide. © 2009 by Nova Science Publishers, Inc.
