Ecosystems experience stress from a number of factors, but a changing climate exacerbates those stressors and alters ecosystem and soil productivity, leading to degradation of wildlife habitat and agricultural productivity. Response to these enhanced stressors requires that farmers, ranchers, and wildlife managers have the necessary information and resources to guide adaptive management...

Areas along the Arctic coast are changing the fastest among all of Earth’s habitats due to climate change. The Arctic coast is a fragile ecosystem that provides habitat for migratory birds, endangered species, and species critical for local subsistence living. In this area, permafrost is thawing rapidly, changing how much and when water reaches rivers, ponds, lakes, wetlands and...

Actionable science has evolved rapidly over the last decade, and the Climate Adaptation Science Center (CASC) network has established itself as a leader in the field. The practice of actionable science is generally described as user-focused, action-oriented science that addresses pressing real-world climate adaptation challenges. It is also sometimes referred to as usable science...

With increasing sea surface temperatures due to climate change, harmful algal blooms in Alaska marine waters are becoming more severe, threatening food security and public health by reducing availability and safety of shellfish and other marine food resources. Paralytic shellfish poisoning, a neurotoxin primarily produced by marine phytoplankton Alexandrium, is the most severe and...

The southeast United States has many lakes, streams and reservoirs that serve as important drinking water sources, recreational, agricultural, and ecological uses. Unfortunately, harmful algal blooms are becoming more common in these waters, causing health issues for humans and animals. While it is clear that nutrients stimulate algae growth, it isn’t clear if there are other parameters...

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...

Climate change has been, is, and will continue to affect Indigenous peoples across the south-central United States, amplifying a need to plan for and adapt to these changes before the impacts become catastrophic. Since June 2012, the South Central Climate Adaptation Science Center (CASC) has partnered with Tribes across Louisiana, New Mexico, Oklahoma, and Texas to conduct research...

State Wildlife Action Plans are intended to provide proactive planning and guidance for the management of rare or imperiled species, including Species of Greatest Conservation Need. States must update their State Wildlife Action Plans every 10 years, but planners often lack the capacity or resources to integrate climate change into their planning. Revised State Wildlife Action Plans for...

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...

Assessments that incorporate areas from land-to-ocean, or “ridge-to-reef", are critical to examine how land-use practices are altering stream discharge and nearshore marine health and productivity. Stream systems in both Alaska and Hawaiʻi are expected to experience changes in water quality associated with changing environmental conditions and increased human-use. Watershed systems...

Wabanaki Tribal Nations (Maliseet, Micmac, Passamaquoddy, and Penobscot) and other Tribal Nations in the Northeast CASC region will face a disproportionate impact from climate change. These impacts will affect resources such as forestry products, fish, game, wild crops, and water that are important to tribal economies and well-being. To combat this, varying levels of tribal community...

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...
