Red Knot Migration and Population Ecology

Eastern Ecological Science Center biologists are studying migration and population ecology of the rufa red knot, a bird species that is dependent on horseshoe crab eggs to complete its trans-hemispheric migration. The birds' spring migration is timed with spawning of horseshoe crabs because the eggs are the perfect food for a migrating red knot.

Conservation Genetics and Genomics of the Narrowly Endemic Island Marble Butterfly Euchloe ausonides insulanus

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 that...

Climate change forecasts for eastern salmonids

Small streams in forests are likely to see dramatic shifts as global climate change influences air temperature and rain patterns. We have already seen warmer stream temperatures as air temperatures increase in summer in the Northeastern US. The intensity and duration of floods and droughts are also expected to magnify as future rain patterns shift. This project will evaluate how stream temperature...

Establishing Molecular Methods to Quantitatively Profile Stomach Diet Items of Fish—Application to the Invasive Blue Catfish (Ictalurus furcatus)

USGS scientists are collaborating with the Maryland Department of Natural Resources (MDDNR) to develop and evaluate a genetic assay for blue catfish fish diets that will allow us to design a cost-effective monitoring program for determining the diet of wild fish.

Assessment of the immune status of wild and laboratory-maintained smallmouth bass

Deaths of young-of-year smallmouth bass in the Chesapeake Bay drainage has been noted since 2005. Studies of affected fish have found bacterial, viral and parasitic infections. Mixed infections suggest these fish are immunosuppressed. Understanding the role of specific pathogens and environmental factors that contribute to their presence is important but equally important is the understanding of...
