Human–Wildlife Interactions

Studying physiologic stress responses can assist in understanding the welfare of animals. One method of measuring the physiologic stress response is evaluating concentrations of glucocorticoid metabolites in feces. Previously, using an adrenocorticotropic hormone challenge, we found fecal glucocorticoid metabolite levels were a reliable indicator of physiologic stress response in coyotes (Canis latrans). We determine whether glucocorticoid metabolite concentrations remain stable when collecting feces over a 2-week period, a timeframe commonly used in scat surveys for wild canids. We collected feces from 6 captive coyotes maintained at the U.S. Department of Agriculture, Wildlife Services, National Wildlife Research Center, Predator …


Food Habits And Anthropogenic Supplementation In Coyote Diets Along An Urban-Rural Gradient, Erica Santana, Jim Armstrong Sep 2017

Food Habits And Anthropogenic Supplementation In Coyote Diets Along An Urban-Rural Gradient, Erica Santana, Jim Armstrong

Human–Wildlife Interactions

Coyotes are recent colonists of the Southeast and have broadened their niche to include exploitation of urban areas. The aim of this study was to examine diet of coyotes inhabiting areas of differential development by humans and assess prevalence of anthropogenic feeding, to detect a possible shift in dietary trends. In urban, exurban, and rural areas of east-central Alabama, 159 fecal samples were collected and examined to reconstruct the diet. Consumption of anthropogenic food did not vary significantly along an urban-rural gradient and foods consumed were similar among habitats. While results of this study can provide insight to guide decisions …

Management Of Predators, Prey, And Aviation Safety At Naval Air Station Patuxent River, Maryland: Can Coyotes Help Reduce Deer Strike Hazards?, Robert Lewis

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

In the past 100 years, coyotes (Canis latrans) have expanded their range eastward. During their expansion, coyotes hybridized with gray wolves (Canis lupus) in the north and red wolves (Canis rufus) in the south. Coyotes were historically occupants of the plains, but now may be found in environments as varied as the sagebrush steppe, deserts, swamps, and inner cities. St. Mary’s County, MD, home to Naval Air Station Patuxent River (Pax River), was one of the last counties in the country to be colonized by coyotes. Pax River is a research and development/flight test and evaluation center, and houses numerous …
