Co-occurrence of Vulpes macrotis and Canis latrans (Carnivora: Canidae) in the Mapimí Biosphere Reserve, Mexico. Rev. Mex. Biodiv. [online]. 2020, vol.91, e912973.  Epub 01-Mar-2021.

Coyote and kit fox are 2 canids that live in sympatry in the arid zones of North America, where it has been reported that one of the main causes of kit fox mortality is the predation by coyotes. However, no mortality event has been reported in the Chihuahuan Desert and little is known about the interaction of these 2 species. Therefore, the aim of this study is to analyze the co-occurrence patterns of both canids in the Biosphere Reserve of Mapimí (BRM), Mexico. For this reason, single and 2 species occupancy models were used, along with covariates. The results of the 2 species models indicate that both canids occur independently, so spatial segregation is not fulfilled. On the contrary, both species were more likely to be detected in the same sites. It is possible that fox adopt surveillance and evasion of predation strategies at a fine spatial scale, which together with the availability of prey allow it to coexist in low numbers at the same places as coyotes.
