Activity overlap of carnivores, their potential wild prey, and temporal segregation, with livestock in a Biosphere Reserve in the Chihuahuan Desert

Abstract

Daily activity is an important aspect of animal behavior and depends both on nutritional and reproductive demands. It also can be modified by—among other factors—interspecific competition, the need to minimize the risk of predation, and human disturbance, such as the presence of cattle. We studied the activity patterns and degree of overlap among carnivores, their potential wild prey, and livestock, in a Biosphere Reserve in the Chihuahuan Desert. There was no temporal segregation among the carnivores. Carnivores synchronized their activity with that of their main prey, the black-tailed jackrabbit (Lepus californicus). In contrast, we did observe temporal segregation between the puma (Puma concolor), coyote (Canis latrans), and bobcat (Lynx rufus), with mule deer (Odocoileus hemionus). There was little activity overlap between predators and livestock (Bos taurus, Equus caballus). However, to avoid conflict resulting from livestock predation we suggest increasing and improving surveillance, and that calves and females close to calving be sheltered. More studies on the multi-niche interactions of livestock and their wild predators are needed to understand daily activity overlap in different seasons, and to better understand the mechanisms of coexistence in protected areas in order to make sound management recommendations to cattle growers and park rangers.

“…Since this coefficient is a descriptive measurement [34], we also calculated Watson's non-parametric two sample U 2 statistics to test for significant differences in species temporal activity patterns. This test is often used to determine whether two or more circular distribution datasets are homogenous [35][36][37].…”

“…Camera traps are widely used to assess the diversity and efficiently estimate the absolute densities of mammals that have coat patterns. The time data extracted from these camera trap records are useful in assessing the activity pattern and understanding the interaction between these mammalian guilds (Santos et al 2019;Durán-Antonio et al 2020;Shankar et al 2020;Shameer et al 2021). This further helps us to understand the ecology of several elusive species and assist managers in maximizing conservation in biodiversity rich areas.…”
