英文摘要	Free water can influence the ecology of desert species. While the use of free water is influenced by physiological factors (e.g., species-specific water requirements, moisture in forage, temperature), nonphysiological factors, such as habitat characteristics and interspecific interactions, are also important. In fact, for species of concern, interspecific interactions and habitat can be important factors influencing their spatial and temporal use of the landscape and its resources. The kit fox (Vulpes macrotis) is a small carnivore considered to be a species of concern over much of its range, and two of the most important conservation challenges it faces are related to (1) habitat and (2) predation/competition by intraguild species. Our objective was to determine the influence of habitat characteristics, predators (bobcats [Lynx rufus], coyotes [Canis latrans]), and potential competitors (badgers [Taxidea taxus], gray foxes [Urocyon cinereoargenteus]) on the use of water by kit foxes. From June to September 2010-2012, we used remote cameras to monitor carnivores at 63 water sources in the Mojave Desert. We used zero-inflated mixed-effects models and a two-stage model selection analysis to evaluate the influence of habitat, predators, and competitors on spatial visits to water by kit foxes. We also assessed temporal avoidance of intraguild predators and competitors by kit foxes at water sources using a coefficient of overlap. We found that visual obscurity, overhead canopy cover, badgers, and coyotes influenced spatial visits of kit foxes. In addition, kit foxes exhibited strong temporal overlap with badgers and bobcats, moderate temporal overlap with gray foxes, and weak temporal overlap with coyotes. Taken together, our study demonstrates that the spatial and temporal use of water sources by kit foxes is dynamic, depending on habitat characteristics and the activity of intraguild predators and competitors.
