Behavioral differences at scent stations between two exploited species of desert canids.

Coyotes (Canis latrans) and kit foxes (Vulpes macrotis) are desert canids that share ecological similarities, but have disparate histories with anthropogenic pressure that may influence their responses towards novel stimuli. We used remote cameras to investigate response to novel stimuli for these two species. We predicted that coyotes (heavily pressured species) would be more wary towards novel stimuli on unprotected land (canid harvest activities are permitted) than in protected areas (canid harvest activities are not permitted), whereas kit foxes (less pressured species) would exhibit no difference.

The influence of periodic increases of human activity on crepuscular and nocturnal mammals: Testing the weekend effect.

Human recreation can negatively affect wildlife, particularly on weekends when human activity is highest (i.e., the weekend effect).

Water developments and canids in two North American deserts: a test of the indirect effect of water hypothesis.

Anthropogenic modifications to landscapes intended to benefit wildlife may negatively influence wildlife communities. Anthropogenic provisioning of free water (water developments) to enhance abundance and distribution of wildlife is a common management practice in arid regions where water is limiting. Despite the long-term and widespread use of water developments, little is known about how they influence native species.

Vigilance of kit foxes at water sources: a test of competing hypotheses for a solitary carnivore subject to predation.

Animals that are potential prey do not respond equally to direct and indirect cues related to risk of predation. Based on differential responses to cues, three hypotheses have been proposed to explain spatial variation in vigilance behavior. The predator-vigilance hypothesis proposes that prey increase vigilance where there is evidence of predators.
