The Prairie Pothole Region is recognized as one of the most productive areas for waterfowl in North America and supports an estimated 50–80 % of the continent’s duck population. This important habitat is threatened by climate change and continued land-use change. The goal of this research is to establish a framework for assessing future impacts of climate and land-use change on Prairie...

Healthy wetlands provide buffers against drought, flooding, pollution, and other threats to humans and nature. Climate change imperils wetland health, including impacting the connections among wetlands that facilitate movements and prevent extinctions of wetland-dependent wildlife. One wildlife group of considerable conservation concern and vulnerability to climate induced wetland...

Ecosystems such as coral reefs and mangroves provide an effective first line of defense against coastal hazards and represent a promising nature-based solution to adapt to sea-level rise. In many areas, coral reefs cause waves to break and lose energy, allowing for sediment to accumulate on the inshore portion of reef flats (i.e. the shallowest, flattest part of a reef) and mangroves to...

In the Gulf of Alaska, streams will experience more dramatic low water events, interspersed with larger and potentially more frequent high flow events in the coming decades. Reduced stream flows are likely to occur due to diminished snowpack and seasonal droughts, while higher flow events are likely to occur with more frequent storms and rain-on-snow events. These changes are likely to...

Yellow perch and alewife are ecologically, economically, and culturally important fish species in Lake Michigan whose populations support recreational and commercial fisheries. However, both of these species’ populations have been in decline for over 20 years. This project seeks to understand the factors affecting variability in offspring survival of yellow perch and alewife in Lake...

Cold-water adapted Brook Trout were historically widely distributed – ranging from northern Quebec to Georgia, and from the Atlantic Ocean to Manitoba in the north, and along the Appalachian ridge in the south. However, studies show that due to factors associated with climate change, such as increased stream temperature and changing water flow, the number of streams containing Brook...

The Science Issue and Relevance: Coastal wetlands are some of the most productive and valuable habitats in the world. Louisiana contains 40% of the United States’ coastal wetlands, which provide critical habitat for waterfowl and fisheries, as well as many other benefits, such as storm surge protection for coastal communities. In terms of ecosystem services, biological resource...

The northwestern United States (Oregon, Washington, Idaho, and western Montana) are experiencing increasing air temperatures, declines in snowpack, altered hydrology, and more frequent and severe wildfire, drought, and insect and disease outbreaks as a result of climate change. These factors, alone and in combination with existing non-climate stressors, present a significant challenge to...

Climate change is already affecting ecosystems, and will likely trigger significant and permanent changes in both ecological and human communities. Such transformations are already occurring in the Arctic region of Alaska, where temperatures are warming at twice the global average and causing some ecosystems to transition to new states. Arctic warming has led to coastal erosion that has...

Overview Fishes of the Adirondack Park face numerous challenges. Summer Suckers are the only endemic vertebrate yet have suffered major range reductions, so we are analyzing their genome, body shape, and spawning timing to verify their uniqueness and current range. Warming patterns are expected to shift their spawning earlier, potentially intersecting with their recent ancestor (White...

A rapidly changing climate and expanding human footprint is driving increased rates of landscape change in the Pacific Northwest. This makes it challenging for managers to know if and to what extent recovery goals and conservation plans for at-risk species need to be modified to account for changing habitat conditions. Addressing this challenge requires accurate, up-to-date information...

The Nisqually River Delta represents the largest wetland restoration in the Pacific Northwest. The restoration resulted in a 50% increase in potential salt marsh habitat. The Delta supports threatened salmon fisheries, large populations of migratory birds, and provides unique opportunities for recreation. The Delta also provides multiple ecosystem services, which are the benefits that...
