Xenomys nelsoni predation by the snake Senticolis triaspis in México

Abstract

Dry jungles harbor a large number of species with restricted distribution or endemic, and little is known about the ecological processes involving these species. Such as activity periods, diet, or predation. In October 2016, we registered a predation event on the Mexican endemic rodent Xenomys nelsoni by the colubrid snake Senticolis triapsis in the Chamela-Cuixmala Biosphere Reserve. This rodent species is listed as endangered by the Mexican law. This is the first report of predation on individuals of this threatened rodent genus.
