Testing a West Nile virus vaccine in sandhill cranes (Grus canadensis) Testing a West Nile virus vaccine in sandhill cranes (Grus canadensis)

Eight sandhill cranes (Grus canadensis) were vaccinated with a commercial equine West Nile virus vaccine (Fort Dodge Animal Health, Fort Dodge, Iowa, USA) at the USGS Patuxent Wildlife Research Center, Laurel, Maryland, USA. Three doses of the vaccine were given, the first dose (day 0) was followed by a second 21 days later and the third dose 7 days after the second day 28 after the...

The effect of varying protein levels on blood chemistry, food consumption, and behavior of captive seaducks The effect of varying protein levels on blood chemistry, food consumption, and behavior of captive seaducks

The Chesapeake Bay is a primary wintering area for scoters and the long-tailed ducks (Clangia hyemalis) that migrate along the Atlantic Flyway. Recently, the Chesapeake Bay had undergone an ecosystem shift and little is known about how this is affecting the seaduck populations. We are determining what are the preferred food sources of the seaducks wintering on the Bay and analyzing the...

The role of fire in structuring sagebrush habitats and bird communities The role of fire in structuring sagebrush habitats and bird communities

Fire is a dominant and highly visible disturbance in sagebrush (Artemisia spp.) ecosystems. In lower elevation, xeric sagebrush communities, the role of fire has changed in recent decades from an infrequent disturbance maintaining a landscape mosaic and facilitating community processes to frequent events that alter sagebrush communities to exotic vegetation, from which restoration is...

Urbanization effects on fishes and habitat quality in a southern Piedmont river basin Urbanization effects on fishes and habitat quality in a southern Piedmont river basin

We quantified the relationships among urban land cover, fishes, and habitat quality to determine how fish assemblages respond to urbanization and if a habitat index can be used as an indirect measure of urban effects on stream ecosystems. We sampled 30 wadeable streams along an urban gradient (5?37% urban land cover) in the Etowah River basin, Georgia. Fish assemblages, sampled by...
