Habitat suitability for Swietenia macrophylla in climate change scenarios in Mexico Autors: Ramírez-Magil, Gregorio, Botello, Francisco, Navarro-Martínez, María Angélica

“…For the 2050 scenario, a loss of suitable habitat of 39.8% is projected, while for the 2070 scenario this loss is 47.6% compared to the 1960-1990 scenario. It is concluded that under both future scenarios, suitable habitat conditions will remain mainly in the states of Campeche and Quintana Roo, the latter of which will conserve about 50% of the suitable habitat. …”
