Trophic interactions between two sympatric mesocarnivores in an anthropized landscape from the Mexican highlands

The study of diets in North American carnivores has been assessed from different methods, essentially analyzing the composition of their diet, and classifying the species based on the breadth of their trophic niche. Still, studies that explore aspects of their interactions are limited. This work studies the predator-prey relationship through an interaction network analysis approach, nesting, and the analysis of core vs peripheral individuals, for two sympatric species of the Mexican highlands, the bobcat (Lynx rufus) and the coyote (Canis latrans). In addition, the effect on the structure of the interaction networks under two conditions of environmental disturbance was evaluated. In environments with high disturbance: A network was obtained for 46 bobcats and 18 coyotes, identifying six bobcats and five core coyotes; and in environments with low disturbance, the network was obtained for 134 bobcats and 38 coyotes, identifying 30 bobcats and eight core coyotes. Three of the analyzed networks presented a nested pattern with the WNOFD metric (High disturbance: L. rufus: Nesting = 0.51, p
