Species are adapted to particular environmental conditions, but are threatened as climate change shifts habitat conditions. One way species can respond is by moving to new suitable locations, known as climate-driven range shifts. But some species can move more easily and/or more quickly than others, and some landscapes are more difficult to cross. In the upper Midwest, the movement potential of many species is reduced by broad expanses of row-crop agriculture, roads and other types of development that fragment the remaining habitat. It is important to sustain and improve connectivity across landscapes so they can continue to support biodiversity and ecosystem services like water filtration, carbon storage, pollinator...

Many amphibian species are highly susceptible to changes in precipitation timing and volume because of their reliance on intermittently flooded surface water pools, which are primarily filled through snowmelt and precipitation runoff. ​With increasing evapotranspiration (i.e. transfer of water from land to the atmosphere) due to climate change, the timing and availability of water in key amphibian reproductive habitats will likely be altered. This project will assess the future risk to amphibian populations in the Midwest, identifying present and future richness hotspots and those wetland species and populations most at risk of habitat loss due to climate change. The research team will model landscape level changes...

Hawaiʻi and the United States Affiliated Pacific Islands face unique challenges in adapting to climate change due to geographic isolation, coastal hazards, close cultural and economic links natural resources, and underserved populations. To address these problems, the PI-CASC works to develop actionable research products through collaborative engagement with cultural and natural resource manager to ensure applicability of the research. In efforts to further support these co-production processes, the PI-CASC Management Climate Corps was developed to connect local natural resource managers, researchers, cultural practitioners, policy professionals, community leaders, and graduate students on Hawaiʻi Islands. The...
The Bluestone sculpin (Cottus sp.) is a priority at-risk freshwater fish endemic to the Bluestone River system in Virginia and West Virginia. The species occurs in small, cool streams with gravel and rubble dominated substrates. The taxonomic status of the Bluestone sculpin is unresolved, and its range often overlaps with congeners, with which it may hybridize. To address the conservation status of the Bluestone sculpin, taxonomic analyses are needed to fully describe the species and evaluate the level of hybridization. Additionally, comprehensive surveys and genetic analyses are needed to determine the species range and population connectivity. Locating the species using eDNA may be a viable option.

Salmon runs are an important time when salmon migrate from the ocean to freshwater, swimming upriver to reach spawning beds. These annual events provide an important food source for both predators and for local communities. However, Recent declines in salmon runs have caused hardship in subsistence fishing communities throughout Alaska, particularly in the Yukon River Basin. To adapt to a changing climate, fishing communities, natural resource managers, and scientists need to measure and understand climate impacts onto salmon runs in this region. To monitor changes in salmon populations and manage fisheries, the Alaska Department of Fish and Game (ADFG), U.S. Fish and Wildlife Service (USFWS), and Tanana Chiefs...

Scientific information can be used to help individuals, communities, and governments alike make more informed decisions. However, for people to become aware of the science that could inform their decisions and its relevance to their lives and decisions, it must be communicated effectively. Multiple obstacles prevent this from happening, including scientists’ lack of time and communication expertise, among other barriers. This pilot project is a novel internship program that pairs student interns with USGS scientists to assist with field-based natural or physical science research in Alaska, while also providing support to the teams of interns and scientists to generate creative and durable science communication...

Coastal flooding and erosion caused by storms and sea-level rise threaten infrastructure and public safety in Alaska Native communities. Though the problem is well known, there are few tools that can assess local vulnerability to coastal flood hazards. Even fewer tools can be customized with specific community information to support local adaptation planning. The main goal of this project is to use the Coastal Storm Modeling System (CoSMoS) platform to co-produce customized local flood hazard maps and online tools to support the development of culturally-appropriate and cost-efficient adaptation strategies in Alaska. The project team will work with federal, state, and local community representatives to understand...

The roselaari subspecies of Red Knot is one of the rarest shorebird populations breeding in North America, based on a the current population size estimate of 17,000 individuals (Carmona et al 2013). As a result of suspected declines,the roselaari subspecies has been designated as threatened by the Committee on the Status of Endangered Wildlife in Canada and was petitioned for listing under the U.S. Endangered Species Act. The U.S. Fish and Wildlife Service’s decision to not conduct a full status review for listing was based on the lack of substantial information identifying threats and population trends (USFWS 2011). The apparent low population size coupled with the scarcity of information on many demographic and...

Many North American shorebird species are experiencing significant population declines, but we have incomplete information about the population sizes and trends for most species. Conservation efforts are underway throughout the Hemisphere to reverse these declines, but we cannot measure the success of those efforts until we have an accurate assessment of population sizes and trends. The Program for Regional and International Shorebird Monitoring (PRISM) is a broad-scale, multi-national effort to monitor both the sizes and trends of shorebird populations (https://www.shorebirdplan.org/science/program-for-regional-and-international-shorebird-monitoring/). PRISM also strives to describe the distribution and habitat...

Climatic warming has contributed to recent increases in severe wildfires across the Pacific Northwest (PNW). Following severe wildfire, a burned forest has an increased likelihood burning again within several decades, which can greatly alter vegetation recovery. These changes are of increasing concern to forest managers, conservationists, researchers, the public, and culture bearers. However, more information is needed to gauge how PNW forests respond to severe wildfire reburns under ongoing climate change. In this project, researchers and natural resource managers will jointly develop new applied science to anticipate and gauge the resilience of forests in the western Cascades of the PNW to climate change impacts....

Steep, mountainous watersheds, dramatic climate gradients, and tight links between the land and sea are common features of both the Pacific Islands and Southeast Alaska. In these "ridge-to-reef" and “icefield-to-ocean" ecosystems, environmental changes that occur at higher elevations have downstream impacts on the waters below. Today, these two ecosystems are undergoing changes in climate that are significantly impacting the terrestrial, freshwater, and coastal ecosystems that communities rely on for food, water, recreation, and tourism. For example, changing weather patterns are leading to more frequent and severe extreme storms, atmospheric rivers, droughts, and heat waves. Communities in both regions have deep...

Reproductive success is a key demographic parameter that can have profound impacts on a species’ population trend; however, broad-scale nest survival data are unavailable for all Arctic-breeding shorebird species. Accordingly, we set out to 1) measure current nest survival rates across a large area of the Arctic National Wildlife Refuge, and 2) identify predators of nests, so as to help elucidate the potential role reproductive failure plays in current shorebird population declines. This information is also relevant for assessing the indirect effects of land management decisions such as oil and gas development on a species’ reproductive success. In 2019 and 2022, we monitored 129 shorebird nests of 9 species using...

Some areas of the U.S. Affiliated Pacific Islands (USAPI) are experiencing a decline in precipitation and streamflow and an increase in the number of severe droughts. These changes can have wide-reaching implications, affecting the water supply, native vegetation and wildlife, wildfire patterns, and the spread of invasive species. As ecosystems become altered by invasive species and as particularly hotter, more variable climates emerge, it is critical that scientists produce locally relevant, timely, and actionable science products for managers to prepare for and cope with the impacts of drought. Simultaneously, it is important that managers are able to both access this information and shape the types of data products...

The Pacific Flyway Winter Brant Survey (WBS) has been conducted annually since 1981 as part of a cooperative effort by the U.S. Fish and Wildlife Service, Canadian Wildlife Service, Mexico, and the Pacific U.S. states, to estimate the abundance of the Pacific black brant (Branta bernicla nigricans) in their principal wintering areas along the Pacific Coast (in Baja, Mexico, California, Oregon, Washington, British Columbia, and Alaska). The survey is conducted each winter in January-February by a composite of ground and aerial crews, with the Alaska portion being conducted by the Alaska Region of USFWS Migratory Bird Management. The primary objective of the Alaska survey component is to provide an annual index of...

The US Virgin Islands are vulnerable to sea level rise, intense storms, and unpredictable rainfall brought by climate change. These changes influence the health of freshwater streams (known as “ghuts”), sedimentation, erosion and water quality (“grit”), as well as aquatic communities and ecosystems (“gills”) that are unique to the islands and important for indigenous peoples’ heritage, local fishermen, tourism, and more. However, the US Virgin Islands have limited water resource data, and the data that exist are scattered across sources, creating an obstacle for adapting water management strategies. Preparing for and responding to climate change requires understanding the threats, priorities, solutions, and funding...
