Bird and Terrestrial Species Conservation

The Challenge: Despite more than a century and a half of study, accurate understanding of the diversity North American mammalian species and the distribution of those species remains unrefined. Yet this understanding is essential for determining the conservation status of species, for mapping out potential disease reservoirs, and for understanding the response of species to habitat perturbation...

The Challenge: The postcranial skeletons of mammals exhibit tremendous variation in form that partly relates to phylogeny (who a particular species is related to) and partly to locomotory function (how that species moves through its environment). Understanding the contributions of these two factors is important because phylogenetic characters assist in working out evolutionary relationships...

The Challenge: Ancient Egyptians mummified animals for a variety of reasons, not the least of which was as votive offerings to certain deities. Among the six species of shrews that have been identified as mummies, one is now extinct, one is no longer occurs in Egypt, and the remaining four have more restricted distributions in the country. One of the latter species also exhibits significantly...

Disease dynamics in wildlife are commonly related to changes or increases in environmental stressors that are placed upon an animal. Environmental pollutants are known to affect the immune system of wildlife, resulting in impaired resistance to infection and potential increases in disease outbreaks. In collaboration with: Jill Jenkins, Ph.D USGS Wetland and Aquatic Research Center; Julia Lankton...

The Waterfowl Breeding Population and Habitat Survey (WBPHS) is a primary source of waterfowl population status and trend information for management of ducks in North America. The survey has not been reviewed in several decades, and since the last review new analysis approaches and information needs have created a need to reassess the design, scope of inference, and analysis of the survey to...

This project seeks to improve our understanding of the susceptibility and pathogenesis of pertinent strains of avian influenza viruses in diving duck species.

This project seeks to quantify the strains and prevalence of avian influenza viruses circulating in wild waterfowl across the Atlantic Flyway, and allow comparison with the nations other flyways.

This project focuses on understanding the prevalence and strains of avian influenza viruses in the aquatic environment and how this compares to those circulating within wild birds in the same area.

This project aims to understand the factors driving breeding success of multiple waterbird species, with special emphasis on Least and Common Terns (two species of concern) on Poplar Island Environmental Restoration Project.

This project is focused on exploring the use of new technology to collect data on colonially nesting waterbird species in ways that reduce disturbance, improve data accuracy, or allow for the examination of previously unanswerable questions.

Declines of pollinators have engendered worldwide concern, but trends in the faunas of most insect pollinators, including bees, remain uncertain. We are studying the bee fauna of southern Rhode Island to provide baseline information about the current fauna, and information about bee-flower interactions.

Agrochemical pollution poses a severe threat to biodiversity. Agrochemicals can detrimentally affect wildlife growth, development, survival, reproduction, and immune responses, which facilitates emergence and spread of infectious diseases that may cause unusually high mortality. Animal microbiota plays a fundamental role in host’s food detoxification and defense against pathogens, regulates...
