Resumen:

México has great biological diversity, but deforestation and climate change threatens its conservation. The loss of biodiversity has been inferred, quantifying deforestation of the principal vegetation types, relating that loss with the reduction in natural habitat. Nonetheless, this scope does not evaluate the impact of deforestation at species level. Climate change is causing changes in climatic regimes that are already impacting in different aspects of biodiversity, like alteration in geographic distributional ranges of species. In this chapter, we integrated habitat loss and climate change to evaluate the effect in the geographic distribution range of a selection of vertebrate species and species from the Opuntia genera in México. Ecological niche models were generated and then projected as distributional ranges. The actual distribution for each species was estimated according to the loss of vegetation types to which these species are associated, using a land use and vegetation map for México. Projections on two different climate change scenarios were done, using scenario A2 (severe or "pessimistic") and B2 (conservative or "non pessimistic") for 2020, 2050 and 2080 in order to anticipate its effect in the distribution of the species selected. © 2012 by Nova Science Publishers, Inc.
