Risk assessment

This project focuses on understanding the forces driving the risk of avian influenza transmission from wild waterfowl to domestic poultry within the Chesapeake Bay region.

There is a growing and urgent need to develop and implement innovative strategies to research, monitor, and manage freshwater resources as societal demands escalate simultaneously with climate-driven changes in water availability.

Southeast Asia has long been the epicenter of AIV emergence. However, as demonstrated by H5NX, these viruses can quickly reach global spread and have significant impacts on poultry production and human health. We have two ongoing efforts funded by the National Science Foundation to help improve our understanding of AIV emergence, spread, and transmission in today’s rapidly changing landscape.

Eastern Ecological Science Center research ecologists are working with state and local partners to develop multiple biological assessments of non-tidal stream and river conditions in the Chesapeake Bay watershed.

The Eastern Ecological Science Center is working closely with federal, state, and tribal partners to help inform decisions that reduce the risk of SARS-CoV-2 transmission from humans to North American wildlife, including bats.

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...

Earthworms are a vital part of a healthy, functioning soil ecosystem and are also an important protein-rich food source for wildlife, including many species of birds and mammals. In an agricultural setting, the presence of earthworms can increase crop yields by 25%, but can also expose earthworms to pesticides. Seed treatment is the principal application method for neonicotinoid insecticides, one...

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...

Streams and rivers provide habitat for a diverse array of aquatic and semi-aquatic species. However, human alteration to landscapes and riverscapes has affected this habitat resulting in its degradation and thus loss of habitat and associated sensitive aquatic species. While this relationship has been known for many years, only recently has the availability of data and analytical capabilities...

Widespread shale oil and gas (unconventional oil and gas, UOG) has only recently begun and many gaps in our knowledge of its potential effects to freshwaters exist.

The island marble butterfly ( Euchloe ausonides insulanus ) was first discovered on Vancouver Island, Canada in 1861. Based on morphological characteristics, it has been described as a subspecies of Euchloe ausonides . After a collection was made in 1908 on Gabriola Island, Canada, the island marble was not seen again until 1998 on San Juan Island, Washington, USA. Recent surveys have determined...

We are working closely with multiple partners to provide updated information, model potential outcomes, and identify key uncertainties relevant to amphibian and reptile species proposed for listing in the northeast US. We also provide timely science to partners to assist in recovery of listed species, which may involve field research, data analysis, or decision support.
