Assessing contaminant exposure and effects at Areas of Concern across the Great Lakes

The Great Lakes Water Quality Agreement designated 31 Areas of Concern (AOCs) across the Great Lakes.  The AOCs are geographical areas where significant beneficial use impairment has occurred as a result of human activities.  A beneficial use impairment (BUI) relates to a change in the chemical, physical, or biological integrity of the Great Lakes system sufficient to cause any of the 14...

Assessing contaminant exposure and effects of contaminants of emerging concern in the Great Lakes Basin

The Great Lakes Water Quality Agreement, in addition to designating 31 Areas of Concern (AOCs) across the Great Lakes, also identified contaminants of emerging (CECs) and mutual concern (CMCs) that warranted additional work not only at AOCs but elsewhere within the Great Lakes Basin.

Common Loon Migration Study

Common loons often migrate several hundred miles to reach coastal waters during fall migration. Information about this part of the loon's life history is not well known.

The use of satellite telemetry allows biologists to track loon movements through distant migrations and during winter. A transmitter attached to a radiomarked loon periodically sends a signal which is detected by a...

U.S. Fish & Wildlife Service - Comprehensive Conservation Plan

The Fish and Wildlife Service (USFWS) has been entrusted to manage our nation’s critical wetland resources. Due to conversion in industrial, residential, and agricultural uses, these wetlands have been disappearing at an alarming rate over the last one-hundred years. In order to better care for these resources, all of the refuges are developing long-term Comprehensive Conservation Plans (CCP...

Waterbird Distribution and Foraging Patterns on the Great Lakes with Respect to Avian Botulism

The Upper Midwest Environmental Sciences Center (UMESC) in La Crosse, Wisconsin is studying the distribution and foraging patterns of sentinel fish-eating waterbirds through aerial surveys, and by tracking migration movements coupled with foraging depth profiles of common loons equipped with archival geo-locator tags and satellite transmitters. The results of this work are expected to...

Boater Compliance with Established Voluntary Waterfowl Avoidance Areas on the Upper Mississippi River

Disturbance to resting and feeding waterfowl on the Upper Mississippi River National Wildlife and Fish Refuge (Refuge) is of utmost concern to refuge managers. Voluntary Waterfowl Avoidance Areas (VWAA) have been established to reduce boating disturbance to migratory waterfowl on Navigation Pools 7 and 8 of the Upper Mississippi River.  Ongoing boater compliance with the VWAA programs has been...

Species Distributional Modeling and Spatial Patterns in Genetic Introgression: the Case of Golden-winged Warblers and Blue-winged Warblers

The Golden-winged Warbler (Vermivora chrysoptera) is a species of considerable conservation concern in North America, primarily due to widespread population declines attributable to habitat loss (Confer et al. 1992, Buehler et al. ) and displacement by the Blue-winged Warbler (V. pinus) in areas of sympatry (Gill 1980, 2004; Will 1986).  Recent research highlighted an important mechanism in...

Assessing the Potential for Climate Change Impacts on the Suitability of Inland Glacial Lakes for Lake-Dependent Biota in the Great Lakes Region

Climate change models predict warmer temperatures, changes to precipitation patterns, and increased evapotranspiration in the Great Lakes region. Such climatic changes have altered, and are expected to further alter hydrological, chemical, and physical properties of inland lakes. Lake-dependent wildlife are often sensitive to changes in water quality, and are particularly susceptible to lake...

Modeling the Distribution and Relative Abundance of Mammalian Predators in the Prairie Pothole Region of Minnesota

Mammalian predation is a major factor influencing waterfowl productivity in the Prairie Pothole Region. Rates of predation of waterfowl nests differ by predator species, so understanding landscape or spatial patterns in predator density are desired by many natural resource managers. Spatial predictions for the occurrence and relative abundance of predators would allow natural resource managers...

Evaluating the Possible Effects of Wind Power Development on Refuging Waterbirds in the Great Plains, Upper Midwest and East Front of Northern Rocky Mountains

We will address the question of whether wind farms can be built near refuges for large concentrations of waterbirds and not cause mortality or critical habitat avoidance. Much is known about many waterbirds (waterfowl, cranes, shorebirds and others) and the places where they concentrate (refuge) during migration. The primary areas of uncertainty in placing wind turbines in relation to the...
