Inland fisheries are critical for global food security and human well-being. However, fish production may be threatened by changes in climate and land use. Understanding this threat is crucial to effectively manage inland fisheries in the future. To address this need, this project will identify which types of lakes across the globe are most vulnerable to the impacts of climate and land use changes. Lakes will be categorized based on their depth, vulnerability to food insecurity, and vulnerability to water insecurity – variables which can all influence how detrimental climate and land use change will actually be on a lake. This information will be used to predict how inland fisheries production might change under...

The stream systems of Hawai‘i are unique and home to many rare species, including five native fish and five native shellfish. These native species have amphidromous life cycles, meaning that they spend part of their lives in the ocean and part in freshwater streams. Stream flow serves as a vital natural pathway, connecting saltwater and freshwater habitats so that these animals can migrate between them and carry out critical life stages (e.g., development, reproduction). Over the last 20 years, the amount of rainfall in Hawai‘i has decreased, and climate models predict that this trend will continue. It is uncertain how reduced rainfall will affect stream flow and, consequently, the native stream species that depend...

Our study addresses the general question of the degree to which wildlife species can adapt to, or possibly even modify, effects from climate change. We focused on five species of mammals in the alpine zone of the Sierra Nevada mountain range, including the federally endangered Sierra Nevada bighorn sheep and the American pika, a species recently proposed for listing due to the loss of populations from altered climatic conditions. It was expected that there will be an upward expansion of trees and shrubs from lower elevations and that many or even most alpine meadows will be converted to woody dominated communities. Meadows provide critical habitat for many alpine mammal species, and their conversion could represent...

Increasing temperatures and decreasing precipitation threaten the persistence of the Rio Grande cutthroat trout, the southernmost subspecies of cutthroat trout, found only in parts of New Mexico and Colorado. This subspecies appears to be more vulnerable to drought than more northern subspecies, because it occupies small and fragmented streams which are at greater risk of drying up during drought. Most notably, in 2002 drought in the Southwest resulted in the loss of 14 different Rio Grande cutthroat trout populations – about 10% of the total population. While it is known that drought is having an effect on Rio Grande cutthroat trout, the specific ways in which individuals and populations are affected by drought...

This project addressed regional climate change effects on aquatic food webs in the Great Lakes. We sought insights by examining Lake Erie as a representative system with a high level of anthropogenic impacts, strong nutrient gradients, seasonal hypoxia, and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may exacerbate hypoxia and reduce habitat volume for some species. We examined fish community composition, fine-scale distribution, prey availability, diets, and biochemical tracers for dominant fishes from study areas with medium-high nutrient levels (mesotrophic, Fairport...

Under the Endangered Species Act, the U.S. Fish and Wildlife Service (USFWS) must evaluate the status of at-risk plants and animals in the U.S. A Species Status Assessment (SSA) is a scientific assessment prepared for each at-risk species to help inform a range of management decisions under the Endangered Species Act. SSA’s are currently needed for more than 350 species, 250 of which are in the Southeast region alone. These species are threatened by several stressors including urbanization, loss of habitat, changes in streamflow and water quality, climate variability, and climate change. As part of the SSA process, teams must identify and assess risks to species or their habitat from changing climate, hydrology,...

The Southeastern and Mid-Atlantic regions of the United States contain the greatest biodiversity of native freshwater mussels in the world, but they are highly imperiled due to habitat alteration and destruction, pollution and poor water quality, and the introduction of aquatic invasive species. Now they are at even greater risk from the stresses associated with climate change-induced sea level rise and its associated changes in salinity, water temperature, and stream flow. This project investigates the potential vulnerability and adaptation of a native freshwater mussel, the Tidewater Mucket, in coastal river systems and offer solutions for its conservation. Scientists have recently discovered a population of...

Barrier islands are exposed to a range of natural and human-caused changes, including hurricanes, sea-level rise, and dredging. These changes have the potential to influence the ability of barrier islands to serve as a first-line of defense for the mainland during storm events. Gulf Islands National Seashore, a National Park Service unit in the northern Gulf of Mexico between Florida and Mississippi, is predominantly comprised of barrier islands and faces immediate challenges, including erosion that washes out roads and sand dunes and the adverse impacts on cultural and natural resources from exposure to saltwater. Managers require realistic estimates of both the vulnerability of the park’s natural and cultural...

Coastal rivers draining into the Gulf of Maine are home to the endangered Gulf of Maine Distinct Population Segment of Atlantic salmon. The Gulf of Maine population began to decline significantly by the late 19th century, leading to the closure of the commercial Atlantic salmon fishery in 1948. In recent years, populations have again begun to decrease again. State and federal fisheries biologists are concerned that climate-related changes in streamflow and temperature could impact salmon survival in these rivers. Projections of future climate conditions for the Northeast indicate warming air temperatures, earlier snowmelt runoff, and decreases in streamflow during the low flow period (summer). In the spring, snow...

Severe droughts cause widespread tree mortality and decreased growth in forests across the globe—even in areas with cooler climates. Mitigating the negative effects of climate change, in particular increased drought frequency and severity, poses a major challenge to forest managers. Managers are searching for strategies that minimize the negative effects of drought on forests (i.e. increase their resistance to drought) and maximize the ability of forests to recover after a drought (i.e. improve their resilience). Evidence suggests that forests with certain combinations of tree species, sizes, and stem densities are better able to withstand and recover from drought. The goal of this study was to identify which...

Modeling the Response of Freshwater Mussels to Changes in Water Temperature, Habitat, and Streamflow
North American freshwater mussels are in serious decline as a result of pollution and habitat destruction from human activities. In addition, many mussel species are living in habitats that push the upper limits of their heat tolerance, which may become problematic as the climate and, as a result, water temperatures warm. As part of this project, we created a set of models to predict how freshwater mussels would respond to climate change effects. Our primary objective was to help federal and state natural resource managers forecast how mussel species will respond to climate change over the next 30 to 50 years, so that managers can develop appropriate adaptation strategies to address these changes. Additionally,...

The number of fish collected in routine monitoring surveys often varies from year to year, from lake to lake, and from location to location within a lake. Although some variability in fish catches is expected across factors such as location and season, we know less about how large-scale disturbances like climate change will influence population variability. The Laurentian Great Lakes in North America are the largest group of freshwater lakes in the world, and they have experienced major changes due to fluctuations in pollution and nutrient loadings, exploitation of natural resources, introductions of non-native species, and shifting climatic patterns. In this project, we analyzed established long-term data about...

Climate change poses a variety of threats to biodiversity. Most efforts to assess the likely impacts of climate change on biodiversity try to rank species based on their vulnerability under changed environmental conditions. These efforts have generally not considered the ability of organisms to adjust their phenotype to the changing environment. Organisms can do this by one of two ways. First, they can adjust their phenotype via non-evolutionary pathways. Second, they can undergo adaptive evolutionary change. We used two interconnected approaches to evaluate thermal adaptation capacity in a cold-water fish species. 1) Using tagging data, we estimated thermal performance curves for wild fish. The curves indicate...

Florida is home to 50 endangered species, 23 National Wildlife Refuges, 9 national parks, and 119 state parks. Straddling both temperate and sub-tropical zones, the state is also unique in that it is a long and narrow peninsula, surrounded on three sides by warm water, creating a dynamic environment. The impacts of climate change, such as sea-level rise and severe storms, threaten the state’s unique biodiversity—yet managers are unsure how species will respond to these changes, which makes planning for the future difficult. In order to identify the impacts of climate change on Florida’s plants and wildlife, researchers developed regional climate scenarios identifying how temperature and precipitation patterns...

If current climate change trends continue, rising sea levels could inundate low-lying islands across the globe. The Northwestern Hawaiian Islands (NWHI) is a group of islands of great conservation importance that is threatened by sea-level rise. Stretching 2,000 km beyond the main Hawaiian Islands, the NWHI are a World Heritage Site and part of the Papahānaumokuākea Marine National Monument. The islands support the largest tropical seabird rookery in the world, providing breeding habitat for 21 species of seabirds, 4 land bird species, and essential habitat for other resident and migratory wildlife. Because these are low-lying islands, even small increases in sea-level could result in the loss of critical habitat,...

Information about streamflow and streamflow variability is critical to assist natural resource managers when they make decisions related to the water needs of both human communities and ecosystems. In order for managers to effectively plan for and adapt to future climate and land cover conditions, they require information on changes that could occur in the distribution and quantity of water resources. Yet every watershed has a unique set of characteristics – such as differing topographies and geology – that affect how much water is available, the sources of water, and how it flows through the system. This means that water availability in every watershed can be affected differently by changes in climate and land...

Walleye, a socially and economically important sportfish across much of North America, are experiencing population declines in many lakes throughout their range. Studies suggest that multiple factors – potentially linked to climate change – are contributing to the decline of walleye, including changes in lake temperatures, loss of habitat, increasing water clarity (perhaps due to drought), and interactions with other fish. This research seeks to identify the mechanisms that underlie declining walleye populations, particularly the low survival rate of young walleye. Data will be collected through a whole-lake experiment, an analysis of long-term data from lakes in northern Wisconsin, and simulation modeling. Members...

Coastal National Wildlife Refuges (NWRs) provide a myriad of beneficial services, including buffering storm surge, improving water quality, supporting commercial fisheries, and providing habitat for imperiled wildlife and plants. Yet in the last century, coastal ecosystems in the eastern U.S. have been severely altered by human development activities as well as sea-level rise and more frequent extreme events related to climate change. These influences threaten the goods and services provided by NWRs and pose decision-making challenges for refuge managers. The purpose of this project was to explore how structured decision-making – a formal, systematic method for analyzing decisions – could help NWR staff make informed...

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,...

Great Lakes fishery managers and stakeholders have little information regarding how climate change could affect the management and conservation of fish populations, including those of high recreational and commercial value. Scientists from the US Geological Survey (USGS) worked closely with state management agencies and the National Wildlife Federation to complete several objectives that provide knowledge to aid their planning and management strategies in anticipation of coming changes. First, researchers updated a regional Great Lakes climate model to predict water level changes, water temperatures, and ice cover data for the entire Great Lakes basin 50-100 years into the future. Second, researchers used satellite...
