Bighorn Sheep and Mountain Goat Research in Western National Park Units

Mountain goat and bighorn sheep are iconic symbols of many national lands in the West. Both species have limited distributions that can be difficult to observe and face multiple stressors including disease, increasing recreation in remote areas, and shifting weather regimes that influence their forage and thermoregulation. As species with relatively small population sizes, understanding...

Shorebird Research

With its vast size and geographic position at the northern end of several migration pathways, Alaska is a critically important site for the world’s shorebirds. Thirty-seven shorebird species regularly breed in Alaska. Most of these species conduct epically long migrations to take advantage of Alaska’s abundant food resources and breeding habitat, making Alaska a global resource for shorebirds...

Wildlife Disease and Environmental Health in Alaska

Environmental health is defined by connections between the physical environment, ecological health, and human health. Current research within the U.S. Geological Survey (USGS) recognizes the importance of this integrated research philosophy, which includes study of disease and pollutants as they pertain to both wildlife and humans. Due to its key geographic location and significant wildlife...

Investigating blotchy bass syndrome in black basses

Black basses (Micropterus spp) are enigmatic North American sportfishes that support the most economically valuable freshwater sport fishery in the United States and serve as keystone predators within aquatic ecosystems. Hyperpigmented melanistic lesions on the surface of black basses have been observed in a number of waterbodies across the country in increasing frequency. We have recently...

Antibiotic Resistant Bacteria in Migratory Birds

Migratory birds, and particularly those using habitats close to human settlements, may be infected with antibiotic resistant bacteria. The USGS is working with public health professionals to understand the role of birds in the maintenance and dispersal of antibiotic resistant bacteria. Additionally, the USGS is investigating how antibiotic resistant bacteria in birds may relate to public and...

Species Affected by Beak Deformities

At least 30 Alaskan bird species are affected and the geographic extent of the problem appears to be growing. In addition to Alaskan observations, we have received increasing numbers of reports from other parts of North America and Europe.

Immune components in eggs of New World blackbirds

Interest in the immune systems of wild birds has increased as public health authorities have recognized that many emerging infectious diseases of wildlife can be transmitted to humans (i.e., zoonoses). Eco-immunology is an emerging field that characterizes how immune adaptations of wild species vary as a result of evolution in different habitats and niches. Present understanding of the influence...

Studying Immune Responses in the American Kestrel (Falco sparverius)

The objectives of this study are to (1) investigate whether the immune system will respond to chemical stressors, such as new flame retardant compounds, and (2) determine if such chemical stressors influence white blood cells (WBC) responses after exposure to a viral pathogen mimicking bird flu.

Assessing Amphibian Disease Risk in the Northeast

Disease in amphibian populations can have a range of effects, from devastating declines following introduction of a novel pathogen to recurring breakout events on a landscape. Elucidating mechanisms underlying the effects of diseases on amphibian populations is crucial to help managers make appropriate decisions to achieve management goals for amphibians.
