Résumé
"The genus Guaiacum belongs to the family Zigophyllaceae, encompassing six species of evergreen trees and shrubs. The geographical distribution model allows designing and creating probabilistic maps of sites where species are distributed. The Maxent program projects patterns of geographic distributions by using ecological niche models. In Mexico, several studies indicate that the distribution of G. coulteri covers 11 Protected Natural Areas (ANP, for their name in Spanish) covering 2,777km2; of this area, 75% corresponds to the states of Oaxaca, Sonora and Sinaloa, data which matches that of the present study. The result of ecological niche modeling for G. coulteri has a coverage of 24,908.238 km2 and the surface of the ANPs is 13,545.76 km2; when overlaying them, the niche area within these is 1,104.42 km2, which corresponds to a coverage of 9.21%. The results suggest that modeling of the potential G. coulteri niche matches the current distribution of the species; although there are areas of modeling that are not found within the ANP, the resulting modeling can be used as a basis for proposing specific fieldwork sites."
