Improving Forage for Honey Bees on USDA Conservation Lands: A Pilot Study for Testing Sampling Methods and Hypothesis Development
Commercial beekeepers have been bringing their bees to the Northern Great Prairie (NGP) for many decades due to the availability of nectar and pollen-rich plants in abundant grasslands.
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.

Vector-borne Disease Research
Lyme disease is the most prevalent vector-borne disease in North America, with about 300,000 cases per year in the U.S. We are studying transmission of the spirochete that causes this disease among wild animals and the blacklegged tick vectors, to determine why Lyme disease is common in the northeast and northern Midwest but rare in the south, even though blacklegged ticks are present in all of...
Warm Freshwater Ecosystems
These systems are characterized as 4th order and larger nontidal riverine systems, which includes many of the intermediate and larger size rivers, such as the Penobscot, Connecticut, Hudson, Delaware, and Susquehanna Rivers and their larger tributaries of the northeastern U.S. Fish passage, thermal stress, and ecological flows are likely important issues in these systems. Fish health issues and...
DNA Barcoding for Identifying Native Bee Species
The Challenge: Traditionally, bee identification has relied on taxonomic methods centered on descriptions of morphological differences between species. However, for many species, separate keys are required for identifying adult males and females and immature life stages. These keys are commonly unavailable. The lack of distinguishing morphological characters useful for separating closely related...
