Predator activity associated with Gopherus flavomarginatus burrows

Sara Isabel Valenzuela, Gamaliel Castañeda

Abstract


Bolson tortoises, Gopherus flavomarginatus (Legler, 1959), are both a flagship and keystone species for the Mapimi Biosphere Reserve.  Burrows of this species can measure over five meters in length and have a depth of 1.6 meters providing shelter for other species. The predation of a black tail-hare (Lepus californicus Gray, 1837) by a coyote (Canis latrans) and a second predation event upon a kangaroo rat (Dipodomys sp.) by a burrowing owl (Athene cunicularia) were recorded. This observations suggest an important role for predator-prey interaction related with the burrows of Bolson Tortoise.
