Over one thousand acres of farmland, open space, and wetlands are converted to residential or commercial development each week in New England. In Massachusetts, nearly two acres of open space land is lost to development every hour. Current development trends suggest that this building pattern, referred to as sprawl, is likely to continue into the near future. Because the negative consequences of sprawl development are highly visible, residents of Massachusetts are becoming increasingly concerned about its impact on their communities. Residents see the unique character of their communities being transformed by uncontrolled residential and commercial development. Green fields and open …

To evaluate whether the abundance of coyotes Canis latrans was influenced by the availability of anthropogenic foods in a humanized landscape, we compared three neighboring areas (hereafter referred to as NA, CA, and SA) under contrasting human pressures within the Santa Monica Mountains of California, USA. We quantified the use of anthropogenic foods by coyotes and assessed local densities within these three regions. Overall, 761 coyote feces were analyzed; identified food items were categorized into 11 food types (7 native and 4 anthropogenic). Though small mammals (lagomorphs and rodents) were the main prey of coyotes in all areas and seasons, …

We examined the relative roles of dominance in agonistic interactions and energetic constraints related to body size in determining local abundances of coyotes (Canis latrans, 8–20 kg), gray foxes (Urocyon cinereoargenteus, 3–5 kg) and bobcats (Felis rufus, 5–15 kg) at three study sites (hereafter referred to as NP, CP, and SP) in the Santa Monica Mountains of California. We hypothesized that the largest and behaviorally dominant species, the coyote, would exploit a wider range of resources (i.e., a higher number of habitat and/or food types) and, consequently, would occur in higher density than the other two carnivores. We evaluated our …
Infectious Disease And The Conservation Of Free-Ranging Large Carnivores, Dennis L. Murray, Cynthia A. Kapke, James F. Evermann, Todd K. Fuller

Large carnivores are of vital importance to the stability and integrity of most ecosystems, but recent declines in free-ranging populations have highlighted the potentially devastating effect of infectious diseases on their conservation. We reviewed the literature on infectious diseases of 34 large (maximum body mass of adults >20 kg) terrestrial carnivore species, 18 of which are considered to be threatened in the wild, and examined reports of antibody prevalence (seroprevalence) and cases of infection, mortality and population decline. Of 52 diseases examined, 44% were viral, 31% bacterial and the remainder were protozoal or fungal. Many infections were endemic in carnivores …
