David Eads is an ecologist with the Fort Collins Science Center. David's research includes aspects of disease ecology, behavioral ecology, predator-prey relationships, and experimental biology.
Most investigations are motivated by applied conservation and efforts to recover federally listed species. Taxa of interest have included carnivores (for example, black-footed ferrets, badgers, coyotes), rodents (for example, prairie dogs, squirrels, mice), arthropods (for example, fleas, lice, ticks, mites), and bacteria (Yersinia pestis). Several ongoing projects concentrate on plague and its chronic effects on wildlife and ecosystems, and methods of effective plague mitigation.
Science and Products
Ecology of Wildlife Disease
Some of the biggest challenges facing wildlife today are changes to their environment from both natural and anthropogenic causes. Natural resource managers, planners, policy makers, industry and private landowners must make informed decisions and policies regarding management, conservation, and restoration of species, habitats, and ecosystem function in response to these changes.
Species Conservation
Large scale changes are occurring to our natural landscapes, often resulting in changes to the distribution and abundance of species living within these landscapes. Populations of many species affected by these natural or anthropogenic changes require focused management to ensure their conservation and sometimes recovery from the brink of extinction.
Ecology of Plague
In North America, the flea transmitted plague bacterium (Yersinia pestis) has colonized and altered native animal communities and ecosystems for more than a century. Many species have suffered adverse consequences from plague, perhaps none more than the endangered black-footed ferret. Plague has established within the ranges of all North American prairie dog species, which collectively serve as...
Effects of Soil and Colony Age on Flea Densities
Abundance of fleas is thought to drive rates of plague transmission in the wild. In the complex process of plague maintenance and transmission, fleas as vectors are a potentially weak link in the system that can be exploited. To date, exploiting this link has provided the only stand-alone tools that are operationally effective for managing plague in the black-footed ferret/prairie dog community (i...
Grassland Ecology and Conservation
Grasslands are arguably one of the most anthropogenically stressed ecosystems of the western United States. The highly endangered black-footed ferret and prairie dogs epitomize grassland mammals of high conservation concern.
Transmission of plague by small mammals at Badlands National Park
Plague was first detected in the southwest corner of Badlands National Park (BADL), and spread northeastward, reaching the northeast corner in 2011. Multiple prairie dog colonies in BADL and Conata Basin have had population collapses from plague since its arrival in the park. Plague is now common throughout BADL (NPS and USFS, unpublished data), and threatens efforts to preserve and manage the...
