Society makes substantial investments in federal, Tribal, state, and private programs to supplement populations of valued species such as stocking fish, planting trees, rebuilding oyster reefs, and restoring prairies. These important efforts require long-term commitment, but climate change is making environmental conditions less predictable and more challenging to navigate. Selection of species for population supplementation is often based on performance prior to release, and one or a few species may then be used for decades even as the environment is changing. When these species are propagated in large numbers, they can become the dominant population as well as genetically overtake any local adaptations. Therefore,...

Small lakes are important to local economies as sources of water supply and places of recreation. Commonly, lakes are considered more desirable for recreation if they are free of the thick weedy vegetation, often comprised of invasive species, that grows around the lake edge. This vegetation makes it difficult to launch boats and swim. In order to reduce this vegetation, a common technique in the Northeast and Midwest U.S. is a ‘winter drawdown’ . In a winter drawdown, the lake level is artificially lowered (via controls in a dam) during the winter to expose shoreline vegetation to freezing conditions, thereby killing them and preserving recreational value of the lake. However, this practice can impact both water...

For the past few years, “king tides,” or the highest tides of the year, have been occurring more frequently and significantly affecting coastal environments across Hawaiʻi. Now, disappearing beaches and waves crashing over roadways are seemingly the “new normal.” In response, the state of Hawaiʻi is implementing adaptation strategies to combat tidal flooding in coastal areas. While flood management strategies are being implemented in urban areas, less is known about how tidal flooding, and associated inundation into surface and groundwater, might influence watershed dynamics and the native animals that depend on estuarine environments where freshwater meets the sea. Efforts for biocultural restoration of ecosystem...

Climate change is causing an increase in the amount of forested area burned by wildfires in the western U.S. The warm, dry post-fire conditions of the region may limit tree regeneration in some areas, potentially causing a shift to non-forest vegetation. Managers are increasingly challenged by the combined impacts of greater wildfire activity, the significant uncertainty about whether forests will recover, and limited resources for reforestation efforts. Simultaneously, there has been an increased focus on post-fire reforestation efforts as tree planting has become a popular climate change mitigation strategy across the nation. Therefore, with increased interest and need, it is crucial to identify where varying...

Overview Fishes of the Adirondack Park face numerous challenges. Summer Suckers are the only endemic vertebrate yet have suffered major range reductions, so we are analyzing their genome, body shape, and spawning timing to verify their uniqueness and current range. Warming patterns are expected to shift their spawning earlier, potentially intersecting with their recent ancestor (White Suckers) to create hybridization and reduced reproductive success. Minnows are more diverse in the Adirondacks, and our analyses suggest that they show three major distributional patterns that reflect post-glacial colonization and temperature preferences. We are analyzing data from hundreds of lakes to discern the rules that structure...

The South Central Climate Adaptation Science Center (CASC) has several Communities of Practice (CoPs) focused on resource manager needs across the region (e.g. understanding at-risk species and ecosystems, building resilient coastal ecosystems, extreme weather and climate change, etc.). Each CoP has expertise in the subject matter and has been working on projects that are relevant to the resource community, including conducting literature reviews and small-scale pilot projects. The current research project will leverage the expertise of the existing CoPs to enhance the content available through the Conservation and Adaptation Resources Toolbox (CART) as identified through the partnership between the South Central...

Elodea spp. (Elodea) is Alaska’s first known invasive aquatic plant, first discovered in urban lakes in 2010. The combination of human pathways and climate change related shifts in seasonality and temperature have resulted in Elodea’s range expansion into Alaska’s freshwater resources. Elodea transmission often occurs when plant fragments get entangled in seaplane rudders and are carried to remote waterbodies where they quickly establish dense plant growth. This growth inhibits seaplane access and drastically alters aquatic ecosystems. Recent research showed that Elodea can have significant negative impacts on parks, subsistence, aviation‐related recreation, and Alaska’s salmon fisheries. For example, the economic...

Changes in stream temperature can have significant impacts on water quality and the health and survival of aquatic fish and wildlife. Water managers, planners, and decision makers are in need of scientific data to help them prepare for and adapt to changes and conserve important resources. Scientists are tasked with ensuring that this data is produced in useful formats and is accessible to these stakeholders. In October 2015, project researchers hosted and facilitated a 1.5 day workshop, “Data Storage, Dissemination and Harvesting”, that brought together over 50 stakeholders from state and federal agencies, tribal governments, universities, and non-profit organizations interested in monitoring stream temperature...

The Jago, Okpilak, and Hulahula rivers in the Arctic are heavily glaciated waterways that are important for fish and wildlife as well as human activities including the provision of food, recreation, and, potentially, resource extraction on the coastal plain. If current glacial melting trends continue, most of the ice in these rivers will disappear in the next 50-100 years. Because of their importance to human and natural communities, it is critical to understand how these rivers and their surrounding environments will be affected by climate change and glacier loss. The overarching goal of this project was to research (1) the amount of river water, sediment, nutrients, and organic matter in the Jago, Okpilak, and...

Recently intensifying drought conditions have caused increased stress to non-native tamarisk vegetation across riparian areas of the San Carlos Apache Tribe (hereafter Tribe) and the Upper Gila River watershed in Arizona and New Mexico. This also increases wildfire risk in the area, making the removal of tamarisk vegetation a primary restoration and climate adaptation objective for the Tribe. The research from this project can improve the Tribe’s capacity to map tamarisk and other riparian vegetation, in addition to monitoring the relative condition and water stress of the vegetation in a timely manner. Specifically, the project will help identify where tamarisk is on the reservation and inform restoration actions...

In the North Central region, invasive species and climate change are intricately linked to changing fire regimes, and together, these drivers can have pronounced effects on ecosystems. When fires burn too hot or too frequently, they can prevent slow-growing native plants from regrowing. When this happens, the landscape can transform into a new type of ecosystem, such as a forest becoming a grassland. This process is known as “ecosystem transformation”. This project will explore key management priorities including native community resilience and management of invasive species, wildfire, and ecosystem change, in a collaboration of researchers working directly with land managers and other stakeholders through the...

Water management in the middle portion of the Rio Grande Basin (between Elephant Butte Reservoir in New Mexico and Presidio, Texas) is challenging because water demand has continued to increase over time despite limited river water and dropping groundwater levels. While urban and agricultural users can cope with frequent droughts by using a combination of river water and pumping groundwater, little to no water reaches living river ecosystems in this region. Improving this situation requires a good understanding of river water and groundwater availability, now and in the future, as well as advantages and disadvantages of water management options to sustain these ecosystems. In particular, there is a need to determine...

While wildlife species do not respect political boundaries, conservation planning and implementation is often restricted by them. Thus, regionally rare species can be placed in the unenviable position of not being prioritized by any jurisdiction that they inhabit due to competition for scarce conservation resources. A regional conservation framework will enable states to cooperate toward common goals and share the costs and accomplishments of regionally conserving at risk species. However, the development of a regional conservation framework is inhibited by patchy species occurrence data. These data gaps can be informed by species distribution models. This project will compile available mussel data, develop species...

Plants convert carbon dioxide into sugars for food during photosynthesis, and this provides food for all animal life. However, photosynthesis is inhibited when a plant’s enzymes use oxygen instead of carbon dioxide. To avoid this use of oxygen, some plants developed a photosynthetic adaptation – called C4 photosynthesis – to concentrate carbon dioxide around the enzymes. While less than 5% of plants use the C4 photosynthetic pathway, they make up ~20% of global terrestrial gross primary productivity. Due to their high productivity, C4 plants have a profound impact on ecosystems, economies, the carbon cycle, and our climate. Corn and sugarcane are both C4 plants, as are foundational western livestock and wildlife...

Mosquito-borne disease is the biggest threat to Hawai‘i’s remaining native forest birds, of which more than half are threatened or endangered. Currently, disease-carrying mosquitoes are unable to move into colder high-elevation forests, but as the islands warm due to climate change, mosquitoes are steadily moving into the last native bird strongholds. Mosquito suppression efforts are planned for three Hawaiian Islands, however, there is currently no monitoring program to assess the effectiveness of those efforts. To address this pressing need, this project will develop new monitoring tools and protocols to provide managers with information about changes in bird and mosquito numbers that are related to climate change...

Water is a key ecosystem service that provides life to vegetation, animals, and human communities. The distribution and flow of water on a landscape influences many ecological functions, such as the distribution and health of vegetation and soil development and function. However, the future of many important water resources remains uncertain. Reduced snowfall and snowpack, earlier spring runoff, increased winter streamflow and flooding, and decreased summer streamflow have all been identified as potential impacts to water resources due to climate change. These factors all influence the water balance in the Pacific Coastal Temperate Rainforest (PCTR). Ensuring healthy flow and availability of water resources is...

Suicide Basin is a glacier-fed lake that branches off Mendenhall Glacier in Juneau, Alaska. Since 2011, Suicide Basin has been collecting melt- and rainwater each summer, creating a temporary glacier-dammed lake. Water that accumulates typically gets released through channels that run beneath the glacier. These channels are normally blocked by ice, but if the water pressure gets too high the channel breaks open, rapidly draining the basin in what is known as an “outburst flood”. In past years, these events have led to flooding along Mendenhall Lake and Mendenhall River in the most heavily populated neighborhood of Juneau. Because of the threats posed to infrastructure in the Mendenhall Valley, it is critical that...

Ducks and other waterfowl in the U.S. are valued and enjoyed by millions of birdwatchers, artists, photographers and citizens for their beauty and appeal. Waterfowl also provide game for hunters throughout the country and act as an important source of revenue for states and local communities. Loss of habitat and migration corridors due to land use changes and changes in climate threaten these birds, however more scientific information is needed to understand these processes. This project used available annual surveys of duck counts, along with data on the location and availability of ponds and temperature and precipitation patterns, to model where across the continental landscape waterfowl were present and if their...
