Wildlife health in human-modified landscapes: epidemiology of tick-borne pathogens affecting black-backed jackals and caracals
Despite the importance of disease as a wildlife management challenge, baseline research on the epidemiology of pathogens occurring in wildlife populations within both rural and urban landscapes has received little attention to date. The aim of this study was to improve our understanding of wildlife …

Shifting disease dynamics following the invasion of an emerging wildlife pathogen
… significant impacts to human, agricultural and wildlife health. Introduced pathogens can change and adapt to new hosts (i.e. the species that they infect) and to new habitats. These factors can ultimately influence their impact on host populations over time. Understanding the changes that occur …

STOMACH CONTENT ANALYSIS OF BOTULISM-AFFECTED BIRDS IN LAKE MICHIGAN
… toxin type E (BoNT/E) at the USGS National Wildlife Health Center. I compare the prey composition and prey sizes consumed by the birds that were collected. Additionally, I examine the diets of culled double-crested cormorants (<em>Phalacrocorax auritus</em>) from three breeding colonies on …

Eukaryotic Parasites of Toxic and Bloom-forming Diatoms: Molecular insights in their diversity and physiology
… microbes in aquatic food webs, human / wildlife health, climate and biogeochemical cycles; their diversity is still widely underinvestigated. This statement is particularly truthful in the case of heterotrophic protists, more difficult to establish as clonal cultures in lab conditions …

One tick closer to a better understanding of tick physiology and how to incorporate tick biology in a classroom
… that can have detrimental effects on human and wildlife health. The pathogens that I. scapularis transmits include the causative agents of Lyme disease and Powassan virus disease. Due to various human impact factors such as global climate change, black-legged ticks have been expanding their …

Health Surveillance of Thinhorn Sheep (Ovis dalli) Herds in British Columbia and Alaska
The health of wildlife populations influences their sustainability in the face of ecological challenges. There is a paucity of information about the health status of free ranging thinhorn sheep populations (Ovis dalli), despite their economic, ecological, and cultural significance. Identification …

How land use influences wildlife occupancy and species richness in the City of Cape Town
… In this study I follow the approach of the Urban Wildlife Information Network by establishing multiple (n=4) transects (ca. 13km long) that extend from natural to suburban and urban land–use in the City of Cape Town (CoCT). A total of 37 camera trap sites were established along these four …

Effects of ambient temperature on mechanisms of pathogen transmission in house finches (Haemorhous mexicanus)
… systems has downstream relevance to human and wildlife health. In this dissertation, I use three laboratory experiments to determine how temperature affects several mechanisms of transmission in a naturally occurring songbird-pathogen system. House finches (Haemorhous mexicanus) are small …

Social and ecological risk factors for mosquito production in residential neighborhoods
… transmit many pathogens that affect human and wildlife health, including West Nile, Zika, dengue, and chikungunya viruses. Since vaccines are not currently available for many of these pathogens, control of the vectors is the most effective method to reduce disease risk. In the United States, …

Modeling the health of free-living Illinois herptiles: an integrated approach incorporating environmental, physiologic, spatiotemporal, and pathogen factors
… and significantly impacted the stability of many wildlife populations. The health of wildlife populations influences their ability to recover from a complex array of anthropogenic and natural stressors. Promotion of positive health status may improve conservation outcomes in wild animals. However, …
