Expanding Distribution of Chronic Wasting Disease

Chronic wasting disease (CWD) has been detected in 26 US states and three Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 24 states and two provinces and in captive cervid facilities in 17 states and three provinces.

Great Lakes Environments

Human activity has caused considerable ecological alterations in the Great Lakes region during the last 150 years and a majority of the most degraded habitats are found along urban coasts. Although strongly affected by human development, urban coasts are home to a variety of species with high ecological, economic, and societal value. USGS is remediating effects of human-induced ecosystem...

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)

The USGS Leetown Science Center (USGS LSC) 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. We will test the utility of this method and, once fully developed, these methods could be...

Mississippi Coastal Improvements Program (MsCIP)

In 2009, the Mississippi Coastal Improvements Program (MsCIP) was developed by the U.S. Army Corps of Engineers (USACE), Mobile District in conjunction with other Federal and State agencies, to help reduce future storm damage along the Mississippi Gulf Coast. The Comprehensive Plan for MsCIP includes restoring the Mississippi barrier islands and over 3,000 acres of wetland and coastal forest...

Alabama Barrier Island Restoration Assessment

This project is a collaborative effort between the USGS, U.S. Army Corps of Engineers (USACE), and the State of Alabama funded by National Fish and Wildlife Foundation (NFWF) to investigate viable, sustainable restoration options that protect and restore the natural resources of Dauphin Island, Alabama. The project is focused on restoration options that protect and restore habitat and living...

Determining carcass scavenging rates on major rivers for oil spill response and NRDAR

The Challenge: Oil spills on rivers often result in bird mortalities and to assess the magnitude of injury to birds following an oil spill, searches are usually conducted for debilitated and dead birds. However these searches underestimate the total number of affected birds because dead or oiled birds can be overlooked by searchers and they can also be missed by searchers...

Does tropospheric ozone, resulting from fossil fuel combustion, disrupt bee pollination?

The Challenge: Pollinators such as bees use floral volatiles to guide them to flowers. Tropospheric ozone produced from fossil fuel combustion products can breakdown floral volatiles. Interference with bee pollination threatens habitat quality and biodiversity and the security of the US food supply system.

Quantitative Framework to Model Risk of Collisions between Marine Wildlife and Boats

Collisons between wildlife and vehicles threaten many species, and can lead to human loss of life, injuries, and loss of property. USGS is developing models to help evaluate the effectiveness of wildlife protection zones and optimize the design of these protected areas.

The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)

Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.
