“…All prey items are in high abundance in the northeastern United States and therefore are preferred by and available to coyotes. Voles and rabbits are also seen in the winter diet of northeastern coyotes [51]. Our results support that idea as well as show insight in to how coyotes are preying on these species.…”

Coyotes (Canis latrans) have been rapidly expanding into the Northeastern Region of the United States since the mid 1900's most likely due to anthropogenic changes in their habitat. Several studies suggest that in addition to being top predators, coyotes are opportunistic feeders and are able to switch prey based on availability and density. Their generalist predation approach allows variation in their diets, and a widespread impact on the ecosystems in which they reside. In this paper, one hundred and seventy seven coyote stomachs were obtained throughout Pennsylvania from 2009-2012 and were dissected to define coyote winter diet. The contents were identified using ad hoc reference bone collections and a set of SEM hair images. Stomach contents were used to identify any correlation between sexual dimorphism and winter diets. It is hypothesized that if Pennsylvania's coyotes show sexual dimorphism, male diets may differ from females. Being able to hunt larger animals may provide males the benefit of a higher caloric return. As a by-product of this research we are detailing a list of prey items found in the winter diet of C. latrans arranged by sex and location.

“…Our study area in Central Europe differs from areas in moderate (Gosselink et al 2003, Switalski 2003 or boreal zones (Elmhagen et al 2002, Helldin andDanielsson 2007) or southern latitudes (Stuart and Stuart 2003, Giannatos 2004, Scheinin et al 2006 when larger predators entered a Carnivora community. Specifically, the diet compositions and consequently food preferences of the competitors rarely differed, and when it did it occurred only over a short period.…”

“…For example, in a temperate agricultural zone of North America, when the grey wolf (Switalski 2003) or the coyote (Canis latrans) (Crooks and Soulé 1999, Gosselink et al 2003, Kamler et al 2003 appeared, they had a significant negative effect on the abundance of smaller carnivores (such as domestic cat Felis catus, red fox, swift fox Vulpes velox). Consequently, smaller carnivores had a lower impact on, e.g., bird populations (Crooks and Soulé 1999).…”

Differences in food preferences between two sympatric canids, the golden jackal (Canis aureus), which is currently spreading from south-east Europe and is a little-known species in Europe, and the red fox (Vulpes vulpes) were investigated. Data on diet composition and food availability were collected over a 13-season period, in a temperate climate agricultural area of Hungary. We found that jackals and foxes preferred small mammals (Ivlev's electivity index, E i s0.38 and 0.39, respectively), and avoided towards wild boar (E i s -0.43 and -0.56, respectively) and cervids (E i s-0.92 and -0.94, respectively). Jackals preferred pheasant less than foxes (E i s0.06 and 0.51, respectively). Within small mammals, both predators preferred the open field living species, with the forest living species being less favoured. The relationship between the available biomass of small mammals, as the primarily important food resource for both canids, and the proportion of consumed biomass of small mammals was not close. This was probably as a result of abundant food resources and high trophic flexibility of the golden jackal and red fox allowing these two closely related carnivores to coexist sympatrically in Central European areas without resource partitioning.

“…On the basis of studies of red foxes in landscapes similar to modern-day Sacramento Valley, we anticipated that proximity to human development conferred protection against coyotes (Dekker 1983;Sargeant et al 1987;Sargeant and Allen 1989;Gosselink et al 2003). We used ArcGIS (v10.0; Environmental Systems Research Institute, Redlands, CA) to project locations of red fox den sites, road kills, and 34,500 randomly generated points (i.e., a density of~three points per square kilometer) and coded them with respect to the three explanatory variables: 1) vegetation class, 2) distance to grasslands (DistGrass), and 3) distance to development (DistDev).…”

The Sacramento Valley red fox Vulpes vulpes patwin of California is a newly named subspecies recently found to be distinct both from other native red foxes and nearby introduced populations. The Sacramento Valley red fox experienced a historical demographic bottleneck resulting in a critically small genetic effective population size, causing concern over its current status and management requirements, yet little is known about its contemporary abundance, demographic trajectory, or habitat use. The hot, arid Sacramento Valley contrasts starkly in climate and physiography with the boreal habitats of other indigenous red foxes in western North America, indicating the need to obtain information specifically on the habitat requirements of this subspecies. A 3-y effort to locate reproductive den sites throughout the Sacramento Valley resulted in 42 independent dens, which we used to obtain preliminary information on habitat use and to develop a distribution model for this subspecies, and 28 Sacramento Valley red foxes killed by vehicles, which we used as independent data to test the models. Foxes were present significantly more than expected in grasslands and less than expected in wetlands and flooded agriculture and also tended to occur in proximity to human development, potentially as refuges from coyotes Canis latrans. We used Maxent to build predictive models. The best model, which incorporated vegetation/land-use classes and proximity to human development, identified 24% of the study area as predicted-presence habitat, which contained 76% of the den sites used to construct the model and 89% of independent locations used to test the model. Our model greatly narrowed the area over which foxes are predicted to occur and will facilitate future surveys to assess occupancy and ultimately abundance and population trends.
