Abstract

ESTRADA-RODRIGUEZ, JL et al. Analysis of the climatic niche of Coryphantha durangensis (Runge ex Schum.) Britton y Rose, 1923, and identification of potential zones for its conservation in the face of climate change. Biotecnia [online]. 2022, vol.24, n.3, pp.63-69.  Epub June 19, 2023.

Coryphantha durangensis is an endemic cactus that lives in Mexico, at the center of the Chihuahuan desert, and is considered a Special Protection by the NOM-059-SEMAR-NAT-2010. Climate change and habitat loss are the greatest threats to this species. In the present study, the climatic niche of C. durangensis was evaluated and the habitat availability of this species was modeled using the MaxEnt algorithm under current climate conditions and future. The results show a reduction in the geographical areas that present climatically suitable conditions for the presence of this species for the years 2050 and 2070. However, four sites were identified, which could be proposed as potential conservation areas for this and other species that cohabit in these zones.

Keywords : suitability; climate; niche; conservation.
