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...

Climate change is expected to increase the intensity and frequency of drought in the U.S., leading to potentially harmful ecological impacts. The uncertain and relatively rapid changes to precipitation patterns pose a significant challenge to managers and decision-makers. In addition to having negative social and economic implications, long periods without rainfall can alter ecosystems, thereby threatening fish and wildlife species. The term “ecological drought” emphasizes the environmental consequences of future droughts. While it is known that ecological drought places multiple stresses on the environment, many of the specific impacts are not fully understood. To address this need, researchers are working to...

The impacts of climate change are widespread and accelerating. As natural resource managers are tasked with maintaining and protecting species and ecosystems, options for minimizing the impacts of climate change are needed. One option for climate adaptation focuses on resistance, which seeks to preserve, as much as possible, the historical structure, composition, and function of an ecosystem in the face of changing climate conditions. One of the primary resistance strategies is to identify and conserve what are known as climate change refugia. These refugia represent areas that remain relatively buffered from contemporary climate change over time and therefore enable the persistence of valued physical, ecological,...

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...

The antelope-like pronghorn is the fastest land animal in North America and has the longest land migration in the continental U.S—in fact, the species has been dubbed “the true marathoners of the American West”. While pronghorns are numerous in parts of their range, such as Wyoming and northern Colorado, they are endangered in others, such as the Sonoran Desert. In the arid Southwest, pronghorn populations have been declining since the 1980s—and it’s thought that drought is partially to blame. Average temperatures in the Southwest have increased 1.6°C since 1901, and the area affected by drought from 2001-2010 was the second largest observed since 1901. Drought conditions have reduced the availability of vegetation,...

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,...

This project produced long simulations (multi-decadal to multi-century in scale) of past, present, and future regional climate at a grid spacing of 50 kilometers (km) over North America and at a grid spacing of 15 km over western and eastern North America. These model runs were the first attempt to achieve coordinated, high-resolution downscaling with such wide geographic and temporal coverage. The objectives of this project were to (1) understand the nature of climate change and variability, (2) quantify the climate-driven responses and feedbacks of terrestrial and aquatic ecosystems, wildfire, the hydrologic cycle, and alpine glaciers, and (3) provide climate information in a form that is useful to a wide range...

One goal of the National Scale Assessment included identifying regions and associated river reaches across the United States that are most vulnerable to projected climate and land use changes. As an initial attempt to characterize river system vulnerability, we followed the definition posed by Kasperson et al. (2006) that incorporates exposure of systems to stresses like climate and land use changes, sensitivity of systems to those changes, and system resilience. This project intended to provide (1) a framework of stream classification to assess vulnerability of fish habitat under future climate change, (2) a framework of stream classification to assess vulnerability of fish habitat with projected urban and agriculture...

Conservation and natural resource managers require information about potential future climate changes for the areas they manage, in terms that are relevant for the specific biotic and environmental resources likely to be affected by climate change. We produced a suite of data sets that provide managers with climate and climate-derived data and a visualization approach that allows managers to map where 1) a managed area's potential future climate is located on today's landscape (i.e., the locations of the modern analogues of future climate) and 2) the areas to which the present climate (and habitat) of managed areas are projected to move. We produced downscaled climate data from historical (1901-2000) data sets and...

The Food and Agriculture Organization of the United Nations (FAO) documents the status and trends of marine fish stocks that represent approximately 80% of global marine catch. These stocks are routinely monitored, and the FAO assessment describes the extent of exploitation against different reference points - such as underfished, sustainable fished, or overfished. Although inland fisheries, which represent 12% of total global capture fishery production, provide important economic and social services, including accessible and affordable high-quality protein to some of the world’s most vulnerable populations, FAO has no comparable system for assessing the state of inland fisheries. This is a critical knowledge gap...

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 Michigan in order to project survival under scenarios of future climate change. Like other fish species, yellow perch and alewives produce huge numbers of small offspring, but most die early in life. Small changes in survival at this early stage can have a strong impact on the number of fish that ultimately contribute to fisheries....

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...

To develop effective adaptive management plans, conservation and natural resource managers need to know how climate change will affect the species and ecosystems they manage. This project provides managers with information about potential climate change effects on species and managed areas in the Pacific Northwest. We evaluated projected changes in climate, vegetation, and species distributions through the year 2099 and assessed the potential impacts of these changes on key species and managed lands. We worked with conservation and natural resource managers to incorporate the results of this study into state, federal, and non-governmental organization (NGO) management plans. The projected changes in climate, vegetation,...

Each year, plants and animals undergo certain life cycle events, such as breeding or flowering. These phenological events are linked to weather and climate, and as temperature and precipitation patterns have changed, some spring events are occurring earlier. These changes in plant phenology can have cascading effects on wildlife such as elk, moose, and mule deer, which depend on plants for food. It’s thought that the quality of forage available in the spring could play a critical role for these big game species, which need to replenish energy depleted during the winter, in order to survive and successfully reproduce. Climate change will alter plant phenology, which in turn is likely to effect when, where, and for...

Previous climate change research for the Colorado River Basin has used down-scaled climate models to predict impacts to hydropower and the potential ability to meet mandated water releases. The Lower Colorado River Basin (LCRB) has one of the most imperiled fish faunas in the nation with about half of the native fish species listed as Threatened or Endangered under the Federal Endangered Species Act. Current water demands for agriculture and human consumption are only slightly less than long-term annual flows. Future projections based on climate change alone indicate decreased precipitation, increased temperatures, and lower annual runoff which will further stress this ecosystem that is experiencing among the highest...

Assessing the vulnerability of wildlife species to a changing climate is critical for understanding what adaptation actions need to be taken to minimize negative impacts. The ability of species to adapt to the impacts of climate change (i.e., their adaptive capacity) is an important factor to consider when assessing vulnerability. For example, organisms can possess traits that allow them to move to areas of favorable habitat or change their phenotypes (observable characteristics) in response to changing environmental conditions. Additionally, an organism’s traits can adapt to a changing external environment over multiple generations through evolutionary processes. Recent scientific evidence suggests that “evolutionary...

The Republic of the Marshall Islands (RMI) is a sovereign Small Island State in the tropical central North Pacific Ocean. RMI is a nation of more than thirty low-lying atolls and islands, most of which are inhabited, dispersed across an EEZ over 2 million square kilometers. Multiple hazards such as coastal flooding, wave overwash, and drought threaten freshwater and food security of the communities. In the atolls, vegetation consists of agroforest, coconut plantation, and coastal species. Because islands/ islets are small and low-lying, all vegetation is vulnerable to the hazards. Current drought hazard products provide generalities regarding conditions on a broad geographic scale, but do not consider exposure of...

High latitude northern ecosystems are currently warming twice as fast as the global average. Over the last several decades, this has caused dramatic losses of frozen area in the Arctic and sub-Arctic. However, it is unclear how melting coastal mountain glaciers, thawing permafrost, and declines in snowpack will affect the quality of freshwater habitat for culturally and economically important salmon in Alaska. As a collaborative effort with the Alaska Department of Fish and Game, the Alaska Department of Natural Resources, and the U.S. Fish and Wildlife Service, this project aims to answer three questions: How does melting affect the freshwater habitat of Pacific salmon? How will changes to aquatic flows...
