Expanding our knowledge of winter limnology is critical for managing lakes , reservoirs, and all freshwater resources in a future with shorter winters and less lake ice. In temperate latitudes, we have largely ignored winter as a season that impacts ecological processes, and it is unclear what ramifications the loss of lake ice will have on lake ecosystems. This project will combine long-term observational datasets, high-frequency buoy data, and an experimental approach to understanding the role of light availability in under-ice productivity

This project examines how leadership within organizations (e.g., C-suite executives) influences organizational and sectoral responses to climate change. This includes prioritization of climate change responses within and beyond organizational boundaries, climate-oriented organizational leadership within and across sectors (e.g., public health, higher education), and the role of institutional leaders in driving change

We worked with stakeholders to develop a series of climate change adaptation management strategies for forests in the Central Hardwoods and Gulf Coastal Plains and Ozarks region. Strategies focused on resistance, resilience, or transition of forests under climate change and vary the types of silvicultural practices considered and where and how much each practice occurs. We implemented strategies in a forest landscape-modeling framework and demonstrated the consequences of these alternative strategies on forest composition and structure in the region. The goal was to provide a large-scale perspective on the potential of forest adaptation strategies to address impacts of climate change on forests

The forests of the Northeastern United States are home to some of the greatest diversity of nesting songbirds in the country. Climate change, shifts in natural disturbance regimes, and invasive species pose threats to forest habitats and bird species in the northeastern United States and represent major challenges to natural resource managers.   Although broad adaptation approaches have been suggested for sustaining forested habitats under global change, it is unclear how effective the implementation of these strategies at local and regional scales will be for maintaining habitat conditions for a broad suite of forest-dependent bird species over time. Moreover, given the diversity in forest stakeholders across the Northeast region, it is unclear if the adaptation science needs for these stakeholders are fully captured by existing adaptation recommendations

The northeastern U.S. is highly exposed to climate change; in fact, the rate of change is higher than most places on earth (Karmalkar and Bradley 2017). The forests of the Northeast CASC region, and the wildlife that inhabit them, are highly vulnerable to the effects of climate change.  In particular, the boreal forests, a biome that reaches from Alaska to the Northeast, and the northern hardwoods, including sugar maple and paper birch, are expected to be intolerant of climate warming. Likewise, many of the birds, mammals, amphibians, fish, and insects that inhabit these forest ecosystems are at their southern range edges here and are considered sensitive to climate change. Furthermore, local species’ adaptive capacity is limited by habitat fragmentation, high rates of invasive species, and other stressors. There is considerable uncertainty with respect to the magnitude and direction of future changes, particularly with respect to interactions with changes in land use and land management, as well as novel interactions amongst co-occurring species. Thus, a focus on climate adaptation in northern forest ecosystems, including evaluations of the impacts of particular actions, is critical. 

Climate change is likely to impact erosion rates, the magnitude and frequency of extreme rainfall/mass wasting events, and the accumulation of sediment in coastal areas. However, long-term rates of erosion and sediment delivery to coastal systems are poorly constrained and there is limited understanding of the relative effects of climate change versus land-use change on these processes. Furthermore, existing instrumental and historical observations are inadequate for constraining the frequency of extreme events and evaluating the potential for changes in the magnitude and frequency of these events through time

The monarch butterfly is in trouble - monarch butterfly habitat has declined throughout most of the United States. Population levels have also exhibited a long-term downward trend with empirical evidence suggesting that loss of habitat is a major factor amongst other threats in driving declines . Preliminary research results from the Monarch Conservation Science Partnership indicates that stabilizing monarch populations will require a "conservation strategy across all land types" - including urban areas. In an effort to connect people with nature in urban areas, the research aimed to answer how best to conserve monarchs in urban areas along the monarchs' central flyway that connects it's over wintering sites in central Mexico to the landscapes of the Midwest

Plants and animals undergo certain recurring life-cycle events, such as migrations between summer and winter habitats or the annual blooming of plants. Known as phenology, the timing of these events is very sensitive to changes in climate (and changes in one species’ phenology can impact entire food webs and ecosystems). Shifts in phenology have been described as a “fingerprint” of the temporal and spatial responses of wildlife to climate change impacts. Thus, phenology provides one of the strongest indicators of the adaptive capacity of organisms or the ability of organisms to cope with future environmental conditions. In this study, researchers explored how the timing and occurrence of a number of highly migratory marine animals is changing due to a series of climatic and ecological shifts

Climate change-driven shifts in distribution and abundance are documented in many species. However, in order to better predict species responses, managers are seeking to understand the mechanisms that are driving these changes, including any thresholds that might soon be crossed. We leveraged the research that has already been supported by the Northeast Climate Adaptation Science Center (NE CASC) and its partners and used the latest modeling techniques combined with robust field data to examine the impact of specific climate variables, land use change, and species interactions on the future distribution and abundance of species of conservation concern. Moreover, we documented biological thresholds related to climate variability and change for critical species in the Northeastern and Midwestern U.S. Our objectives were to identify the primary drivers (e.g

WICCI is a grassroots effort to consolidate information about climate change impacts in Wisconsin.  Its first report, released in 2010, has played a critical role in elevating climate change within dialogue about environmental management across the state, and serves as the go-to resource for agencies, NGOs, and the public.  We are now working to update that document, focusing on new research in aquatic and other ecosystems, as well as case studies of impacts on Wisconsin's ecosystem services. The goals of this project are in part to 1) Compile a synthesis of climate change impacts on people and natural resources of Wisconsin.  2) Provide public education about the seriousness of climate change impacts.  3) Establish accessible and credible reference for policy makers
