Abstract: Understanding the consequences of anthropogenic change for migratory species is challenging because although they have evolved to cope with environmental uncertainty, migrants still rely on predictable relationships within and among habitats to make informed decisions. Calidris shorebirds rely on ephemeral wetlands during northward migration through mid-continental North America, where favorable habitat conditions are annually and regionally unpredictable and increasingly altered by land-use change. During spring 2013 and 2014, we assessed Calidris habitat use in the Rainwater Basin (RWB) and the Prairie Pothole Region (PPR) at both local and landscape scales. Although anthropogenic change has altered...

In the western U.S., rising temperatures and pronounced drought conditions pose significant challenges to public land managers. Widespread declines of multiple plant species have already been observed, providing insight into what the future could look like for vegetation in the region as conditions are projected to become warmer and drier. To understand how vulnerable western ecosystems are to drought, managers need to know which climatic and soil conditions cause habitats to change, and at what rate these changes may occur – important topics on which there is little available data. This project seeks to identify the vulnerability of habitats in the western U.S. to drought. Researchers will compare changes in...

Different species have different ways of coping with changing climate conditions. Some species may move to more-favorable habitats, others may change their behavior (such as by shifting their diets), and still others may change the timing of life-cycle events (such as migration). The ability of a species to accommodate changing conditions is known as its “adaptive capacity”. Understanding the adaptive capacity of different species is a critical component of identifying which species are most vulnerable to climate change, and can ultimately inform the prioritization of conservation efforts. The goal of this project is to create a framework providing natural resource managers with a means of assessing the ability...

Fisheries in the glacial lakes region of the upper Midwest are culturally, economically, and recreationally beneficial. Walleye, for instance, represent an important subsistence food source for some Wisconsin tribal nations and are also popular among recreational anglers. However, predicted ecological changes to these aquatic communities, such as an increase in invasive fish species, a decrease in walleye and other native fishes, and worsening water quality due to increases in temperature and shifts in precipitation, has prompted concern among regional anglers who may abandon certain fisheries as these changes occur. Understanding how changes in climate may affect glacial lakes region fishes, and how fishery managers...

Extreme events not only affect people but can have detrimental impacts on natural resources, such as fish and freshwater habitats. Impacts of extreme events, like hurricanes, tornadoes, and extreme flooding, have immediate consequences, but also have the ability to alter habitats and animals far in the future by providing opportunities for exotic species to colonize new areas. Some fish communities in streams, rivers, and lakes may have the natural ability to resist the long-term impacts of extreme weather events. In this project, researchers will investigate the ability of Caribbean fish assemblages in Puerto Rico, which have both economic and cultural importance, to resist the impacts of extreme weather events....

Fisheries and aquatic habitats throughout the United States are in dire need of protection or restoration because human activities have resulted in severe degradation of those habitats. Further, future climatic changes will continue to affect human land-use, temperature, and water flows. Natural resource managers need to identify and prioritize habitats so that limited time and funding can be focused on habitats that are in most need of protection both now and in the future, based on projected climate changes. This project was comprised of a team of scientists from the US Geological Survey, Kansas State University, Michigan State University, Penn State University, the University of Minnesota-Duluth, the University...

In collaboration with the University of Missouri and Iowa State University, this project advanced efforts to understand and accommodate uncertainty by applying to Missouri River sturgeon population dynamics the tools of multi-scale climate models and hierarchical Bayesian modeling frameworks, linking models for system components together by formal rules of probability. While a complete climate prediction may be intractable at this time -- for instance, the climate projections may not incorporate land use changes and solar fluctuations into the boundary conditions -- we proposed a framework to quantify known uncertainty that is also flexible enough to adapt to advances in climate predictions. A key advantage of the...

Snowshoe hares are the primary food source of the federally threatened Canada lynx. In western Montana for example, snowshoe hare make up 96% of lynx diet. In fact, hares are critical players in forest ecosystems because most carnivores prey on them. The main way that snowshoe hares escape predation is through camouflage. In response to changes in day length, snowshoe hares molt seasonally, changing color from brown to white in the winter to blend in with the snowfall and hide from predators. However, due to shorter snow seasons caused by recent changes in climate, snowshoe hares are turning white before it snows, making them more visible to predators. Because 21 other species around the world also undergo these...

Climate change has emerged as a key environmental concern of the 21st century and a major challenge for land and wildlife managers. Although scientists have made tremendous progress in predicting the impact of climate change on a regional and global scale, drilling down such projections to a locally applicable form has been difficult. A major project of the US Geological Survey's (USGS) Southwest Biological Science Center (SBSC), funded by the USGS National Climate Change and Wildlife Science Center (NCCWSC), drew on the work of an interdisciplinary team of scientists to help close the gap between theory and practical application in the arid southwestern U.S. Climate change in this region is predicted to be extreme,...

The scaled quail is an important species that indicates the overall health of the habitats they occupy in the arid Southwest. Some populations are declining, which may be linked to the long-term trend in warmer, drier conditions and reduced monsoonal rainfall across their range. It’s believed that temperature and humidity levels have been too high, reducing the survival of eggs and chicks. Climate models project decreasing rainfall and warming temperatures to continue for the region, so understanding this linkage is becoming increasingly critical. To address this need, researchers sought to measure the success of scaled quail nests at locations across their range, to determine if nest success is related to temperature,...

Recreational fisheries offer invaluable benefits to the communities they serve, including economic support, food security, and enhanced social connection with natural areas. In North America, bluegill are one of the most important species in terms of providing accessible, harvest-oriented recreational fisheries. In Wisconsin, they are the most caught, most harvested, and second-most targeted species in the state’s recreational fishery. Climate change offers further challenges. Warming temperatures and associated impacts have the potential to affect fish communities and their habitat with unpredictable implications for angler behavior, which can then cause further impacts on fish populations. Significant knowledge...

The Northeast coast of the United States is an important area for a variety of native nesting seabirds including Common, Least, Arctic, and the federally endangered Roseate terns. These species migrate to the Northeast region to take advantage of highly productive waters during late spring and early summer to breed and raise their young. During this period, adults are highly dependent on local prey resources to support chick growth and survival. Long-term diet studies show terns are highly dependent on a few select prey groups, potentially making seabird populations sensitive to changes in prey distribution. This sensitivity is particularly important as many prey species are shifting to new areas in response to...

Freshwater ecosystems support the health and well-being of human life and society through a myriad of services. Intact freshwater biodiversity maintains the health of freshwater ecosystems and the benefits they provide. However, staggering rates of freshwater biodiversity loss and declining ecological function of freshwater ecosystems threaten these natural benefits and human life. This project supports international collaborations to increase awareness and relevant and actionable biodiversity information to support decision makers address freshwater biodiversity loss.

Abstract (from http://link.springer.com/article/10.1007%2Fs12237-013-9694-0): Salt marsh faunas are constrained by specific habitat requirements for marsh elevation relative to sea level and tidal range. As sea level rises, changes in relative elevation of the marsh plain will have differing impacts on the availability of habitat for marsh obligate species. The Wetland Accretion Rate Model for Ecosystem Resilience (WARMER) is a 1-D model of elevation that incorporates both biological and physical processes of vertical marsh accretion. Here, we use WARMER to evaluate changes in marsh surface elevation and the impact of these elevation changes on marsh habitat for specific species of concern. Model results were compared...
