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...

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...

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,...

Fish that are harvested from rivers and lakes play an important role in ensuring global food security. However, data on river fisheries is not collected in any standardized format globally. Although targeted analyses have been conducted on certain river systems, the approaches used, such as intensive field sampling, are not feasible at a global scale. Most river fish are harvested by small-scale operations and in countries that lack the necessary infrastructure and technology that would enable regular reporting of harvests. Therefore, alternative approaches are needed for estimating the harvest potential of river fisheries at a global scale. Given changing climate conditions and the potential impact of these changes...

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...

Marine shellfish are an important diet and cultural resource for many Alaskans. Harmful algal blooms can produce toxins which accumulate in shellfish and can cause disease and death in consumers. Climate change is predicted to expand the timing and strength of harmful algal blooms which may affect food security for many Alaska Native Tribes and communities. Predicting when the shellfish are safe to consume is a critical component of establishing food security and adapting to climate change. Local traditional knowledge from Tlingit elders indicates that herring spawning events, which typically occur in April or May in Southeast Alaska, provide a warning signal for when to stop harvesting shellfish. The environmental...

Alaska is an ecologically, commercially, and recreationally diverse state, providing value to people and terrestrial and aquatic species alike. Presently, Alaska is experiencing climatic change faster than any other area of the United States, but across the state, comprehensive environmental monitoring is logistically difficult and expensive. For instance, only about 1% of U.S Geological Survey (USGS) stream gages are in Alaska, and only about 50% of those gages measure water temperature, an important climate change indicator. In this study, predictive models are being used to map stream temperatures under current and future climate scenarios across the Yukon and Kuskokwim River basins (YKRB) at the stream reach...

The Colorado River and its major tributaries provide a crucial water supply for more than 40 million people in the American Southwest and in California. This water supply is primarily used in irrigated agriculture but also provides essential drinking water to many large metropolitan areas. Hydropower is also produced at many of the large dams on the river. River flows have declined during the past 15 years due to decreasing watershed runoff associated with a warming climate and ongoing drought. Climate projections indicate a continued decrease in future water availability as runoff continues to decline and temperatures warm. Water-users in the Colorado River basin are concerned about this declining water availability...

Climate change has the potential to magnify existing problems in conservation, such as invasive species and disease. This threat is particularly severe in the Klamath Basin, where the fish parasite Ceratonova shastais making national headlines for killing salmon, and invasive trout have extirpated populations of native trout. The Klamath Basin is slated for one of the largest restoration projects in human history involving the removal of 4 mainstem dams. The success of this massive effort will likely depend on how climate, disease, and invasive trout combine to affect fisheries. However, there is currently no data available to incorporate these important interactions into conservation planning. This dearth of information...

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...

The Mississippi River Basin / Gulf Hypoxia Initiative (MRB/GHI), spearheaded by seven LCCs, is undertaking a strategic and transparent process to create an integrated framework that supports planning, design, configuration, and delivery of wildlife conservation practices within the watershed. This framework consists of multiple quantitative objectives representing three interests (i.e., wildlife, water quality, agriculture), a tiered set of conservation strategies to achieve those objectives within five production agriculture systems (i.e., corn & soybean; grazing lands; floodplain forest; rice; cotton), and a modeling approach to determine where to best implement those actions within four key ecological systems...

The Squaxin Island Tribe (SIT) is descended from maritime people who have lived and prospered along the shores of the southernmost inlets of the Salish Sea for millennia. Climate change is projected to result in lower low water flows, higher peak water temperatures, and bigger and more frequent floods, due to both changes in peak flows and sea level rise. These changes could have significant impacts for salmon and other fish populations, while also putting key Tribal properties and enterprises at risk. Given the potential for climate change to exacerbate existing threats on salmon populations, it is necessary to quantify climate change impacts to inform effective restoration and conservation plans. The project...

Freshwater fishes are globally among the most imperiled major biodiversity groups and they are especially endangered in the North American deserts of the vast binational Desert LCC. Sixty seven native fish species of conservation concern are in the study area, which includes all of the DLCC in both the US and Mexico. Essentially all species in our study area are understudied and management of them has been greatly impeded by the intrinsic difficulties of working internationally and by relative lack of, or inaccessibility to, basic knowledge about their distributions and conservation status. We propose to mine data from all online and known US-based institutions holding specimen-based occurrence records from our...

Hydrologic drought and declining water availability are among the foremost stressors of stream ecosystems in the Red River basin. Resource managers face the challenge of apportioning scarce water resources among competing uses, but they lack a systematic framework for comparing the costs and benefits of proposed water management decisions and conservation actions. In 2016, Co-PIs Neeson and Moreno were funded by the Great Plains LCC to develop a decision support model for identifying the most cost-effective water conservation alternatives across the Red River basin. Here, we propose to extend this optimization model in three significant ways to support cost-effective conservation decisions in the face of climate...

Climate change adaptation research has made major advances over the last decade. For example, much is known about the impacts of climate change, many novel adaptation planning approaches have been developed, decision tools have become ubiquitous, and many novel adaptation options have been proposed. However, additional research is needed to demonstrate how these adaptation planning schemes can translate to implementation on the ground. The area in and around the Yosemite and Sequoia National Parks in Southern Sierra Nevada serve as ideal natural laboratories to study the impacts of climate change and the effectiveness of various on-the-ground forest treatments and restoration designs. Southern Sierra Nevada faces...

Many inland bodies of water in western Louisiana are receiving too much sediment and nutrient pollution from upstream which has caused declines in the health of many fisheries. These bodies of water include many traditional lake-based fisheries of the Chitimacha Tribe of Louisiana (CTL), and fisheries used by visitors, providing critical tourism and economic development dollars to the region. The goal of the Coastal Indigenous Fisheries Assessment (CIFA) is to study the long-term health and ecology of fisheries and water bodies in west-central Louisiana. This project will be a collaboration between leaders and scientists from the Chitimacha Tribe of Louisiana, Louisiana State University and Florida State University...

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...

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...

For thousands of years, much of the San Luis Valley basin of south-central Colorado was made up of a series of lakes, marshes, and shallow playa basins that were integral to the lives of indigenous peoples. By the mid-1900s, the basins had dried up from the diversion of water sources for irrigation and became known as the “Dry Lakes.” In 1965, BLM began a series of wildlife habitat projects to restore some of the historic wetland characteristics and processes, and 9,600 acres of the former “Dry Lakes” area became known as Blanca Wetlands. BLM designated the Blanca Wetlands Area (BWA) as an “Area of Critical Environmental Concern” (ACEC) in 1991, due to its high importance for wildlife and recreational values. Today...

Freshwater systems are critically imperiled and continue to be threatened by human encroachment and water development. The upper Gila River in New Mexico is one of the last unobstructed rivers in the Colorado River basin with a mostly intact native fish fauna, including two federally listed and one state-listed fish species. Kansas State University will develop methodologies or decision support tools to assess or evaluate current or existing resource management practices to learn and adapt to the effects of climate change on fish species. The researchers will investigate how the connectivity of the Gila River habitat impacts the fish population with respect to the behavior of native and non-native species.
