This book was released on 2018 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: To ensure reproductive success, Canis species establish contiguous mosaics of territories in suitable habitats to partition space and defend limiting resources. Consequently, Canis species can exert strong effects on prey populations locally because of their year-round maintenance of territories. We assessed prey use by coyotes (Canis latrans) by sampling scats from within known territories in southeastern Alabama and the Savannah River area of Georgia and South Carolina. We accounted for the size and habitat composition of coyote home ranges to investigate the influence of space use, vegetation density, and habitat type on coyote diets. Coyote use of prey was influenced by a combination of mean monthly temperature, home range size, vegetation density, and hardwood forests. For example, coyote use of adult white-tailed deer (Odocoileus virginianus) was associated with cooler months and smaller home ranges, whereas use of rabbits (Sylvilagus spp.) was associated with cooler months, larger home ranges, and less vegetation density. Coyotes in our study relied primarily on nutritionally superior mammalian prey and supplemented their diet with fruit when available, as their use of mammalian prey did not appreciably decrease with increasing use of fruit. We suggest that differential use of prey by coyotes is influenced by habitat heterogeneity within their home ranges, and prey-switching behaviors may stabilize local interactions between coyotes and their food resources to permit stable year-round territories. Given that habitat composition affects coyote prey use, future studies should also incorporate effects of habitat composition on coyote distribution and abundance to further identify coyote influences on prey communities.

This book was released on 1985 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio-telemetry and scat analysis were used to investigate daily and seasonal movement patterns and food selection of a protected coyote population on Tulelake National Wildlife Refuge (TLNWR) and adjacent Lava Beds National Monument (LABE) in northeastern California. Study emphasis was on evaluation of movements on and off the sanctuary, and movements and food selection relative to manipulated and undisturbed sites. Nineteen coyotes were trapped and fitted with either radio-telemetry (12) or color-coded (7) collars between 1 November 1982 and 5 May 1983. Home ranges were estimated for eight sanctuary coyotes (two composites) by two methods: (1) 95% minimum convex polygon (MCP) and (2) 90% contour of the utilization distribution. Home ranges were small (95% MCP's : 0.5 - 6.2 km2) and elongate, including portions of both irrigated cropland (TLNWR SW Sump) and undisturbed rangeland (LABE) habitats. Coyotes used cropland habitat primarily for foraging purposes, and rangeland for resting and denning. Elongate shape reflected movements back and forth between habitats. Territoriality was demonstrated. Intensive monitoring of four coyotes from May through September 1983 indicated coyotes used larger areas at night (1700 to 0900) than in daytime (0900 to 1700) during pup-rearing (23 May to 8 August) and dispersal (15 August to 20 November) seasons. Home ranges and core areas were larger for both diel periods in dispersal season than in pup-rearing season. Variable patterns of coyote use of irrigated cropland habitat were attributed to individual energy demands, human activity, and vegetative cover. Only one individual (adult male) was known to make daily excursions off the protected area. Some seasonal migration off the sanctuary took place in late fall, winter, and early spring. Spring migrations may relate to human disturbance on agricultural lands. Food habits analysis showed coyote diet was more diverse in all seasons on the undisturbed rangeland (LABE) than on the irrigated cropland (SW Sump). Montane voles, Nuttall's cottontails, and mule deer were winter staples on LABE. Many other foods (sciurid and heterormyid rodents, insects, berries, birds) entered LABE coyote diet in late spring and summer. Montane voles were the dominant coyote food year round on SW Sump. Birds entered SW Sump coyote diet in substantial quantities only during pheasant and waterfowl hunting seasons in late fall and winter. A model for optimal use of a patchy habitat and its application to coyote foraging strategy and use of manipulated (simple, homogeneous) versus undisturbed (complex, heterogeneous) environments is discussed, as are some management implications.

Book excerpt: The extent to which predators regulate prey populations remains a subject of debate. Yet, when predator control is employed as a management strategy, it is often assumed that predators can and do regulate prey populations. From 2011 through 2015, I monitored the demography and space use of coyotes (Canis latrans) and cougars (Puma concolor) on Monroe Mountain in Fishlake National Forest, Utah as part of a larger collaboration investigating the impacts of coyote aerial control on mule deer (Odocoileus hemionus) neonate survival. My primary objective was to assess the impacts of anthropogenic regulation on the respective populations and identify any cascading effects relevant to mule deer management. To meet this objective, I established a monitoring program for both predators by deploying radio-telemetry collars (VHF and GPS) on each, documented predation events, established surveys for small mammals and lagomorphs to monitor primary prey populations during deer parturition (June 0́3 August), and collected data on the location and demographic composition of winter-removed coyotes. I analyzed these data primarily in a community-based, animal movement and resource selection framework permitting the integration of data from multiple sources. When evaluating coyote aerial removal as a management strategy, I identified a spatial dependency in the ability to match removals with indices of deer recruitment as Wildlife Services Operations personnel were primarily limited by terrain and tree cover. Thus, matching treatment with deer fawning was highly variable with only a small number of sites where removals were effective. In addition, I found that coyotes selected for sites with the highest densities of lagomorphs while avoiding areas with a high probability of encountering cougars. Coyotes did not select for mule deer fawning sites, although individual coyotes that occupied resource-poor home ranges were more likely to do so. Cougars strongly selected for mule deer high use areas throughout much of the year, only switching to elk (Cervus elaphus) during the cougar harvest season (i.e., winter). Data from cougar kill site investigations match the observed patterns in cougar space use. My results suggest that predator-prey processes are multi-dimensional and dynamic through time, which likely contribute to the lack of resolution regarding the efficacy of predator control and the regulatory potential of predators in general.
