Abstract (from British Ecological Society): A central theme of range‐limit theory (RLT) posits that abiotic factors form high‐latitude/altitude limits, whereas biotic interactions create lower limits. This hypothesis, often credited to Charles Darwin, is a pattern widely assumed to occur in nature. However, abiotic factors can impose constraints on both limits and there is scant evidence to support the latter prediction. Deviations from these predictions may arise from correlations between abiotic factors and biotic interactions, as a lack of data to evaluate the hypothesis, or be an artifact of scale. Combining two tenets of ecology—niche theory and predator–prey theory—provides an opportunity to understand how...

Climate change and the extreme weather associated with it can be a major challenge to landowners and land managers interested in the protection, restoration, recovery, and management of wetlands and wildlife habitats. The Midwest is not only experiencing an increase in average temperatures and precipitation, but also an increase in the frequency of extreme events, such as heat waves and floods. Forecasting the potential impacts of the changes over the next 25 to 50 years will be important for decision makers and landowners seeking to minimize the impacts to infrastructure and to the habitats themselves and prepare for the future. Changes in flood frequency threaten habitat management infrastructure and actions,...

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...
Across the Northeast, 14 States’ Wildlife Action Plans have identified climate change as one of the top five threats to fish and wildlife and their habitats. They further indicate that climate change exacerbates the other four priority threat impacts of pollution, disease, invasive species, and development in the region. This project aims to provide the information and tools to state fish and wildlife agencies to help them address this formidable challenge by working with the NE CASC to fill important data gaps and inform development and implementation of effective fish and wildlife adaptation strategies. Recent surveys show that state fish and wildlife agencies across the nation lack the resources (funding and...
Abstract (from Ecological Indicators): Climate change has and is projected to continue to alter historical regimes of temperature, precipitation, and hydrology. To assess the vulnerability of climate change from a land management perspective and spatially identify where the most extreme changes are anticipated to occur, we worked in collaboration with land managers to develop a climate change vulnerability map for the midwestern United States with a focus on riparian systems. The map is intended for use by regional administrators to help them work across various program areas (e.g. fisheries, endangered species) to prioritize locations needing support for adaptation planning. The tool can also be utilized locally...

Changing climate conditions could have significant impacts on wildlife health. Shifts in temperature and precipitation may directly affect the occurrence of disease in fish and wildlife by altering their interactions with pathogens (such as the bacterium that causes Lyme disease), helping vectors like mosquitoes and ticks expand their range, or speeding up the time it takes for a parasite to develop from an egg to an adult. Climate change can also indirectly affect the health of fish and wildlife as their habitats change. For example, reduced food availability could lead to overcrowding and increased disease transmission, or warmer temperatures might increase stress levels, weakening immune systems and making animals...
Climate change and the extreme weather associated with it can be a major challenge to natural resource managers charged with the protection, restoration, recovery, and management of wetlands and wildlife habitats. Forecasting the potential impacts of climate changes will be important for decision-makers and land managers seeking to minimize impacts to habitats, infrastructure, and wildlife populations and prepare for the future. In collaboration with U.S. Fish and Wildlife Service (FWS) managers, we developed a climate change vulnerability assessment to spatially evaluate climate vulnerabilities across the Midwest region. To create the vulnerability assessment, we convened resource managers and scientists working...

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...
