Extreme events not only affect people but can have detrimental impacts on natural resources, such as fish and freshwater habitats. Impacts of extreme events, like hurricanes, tornadoes, and extreme flooding, have immediate consequences, but also have the ability to alter habitats and animals far in the future by providing opportunities for exotic species to colonize new areas. Some fish

Managing natural resources is fraught with uncertainties around how complex social-ecological systems will respond to management actions and other forces, such as climate. Modeling tools have emerged to help grapple with different aspects of this challenge, but they are often used independently. The purpose of this project is to link two types of commonly-used simulation models (agent...

Inland fisheries make up more than 50% of all food fish in the world. Sustainable inland fisheries can support global economic development by providing food for billions and livelihood for millions of people worldwide. However, it can be difficult to quantitatively track and evaluate the services that inland fisheries provide to communities, which ultimately means that the contributions...

Vernal pools are small, seasonal wetlands that provide critically important seasonal habitat for many amphibian species of conservation concern. Natural resource managers and scientists in the Northeast, as well as the Northeast Refugia Research Coalition, coordinated by the Northeast CSC, recently identified vernal pools as a priority ecosystem to study, and recent revisions to State...

There are approximately 2,000 species of migratory birds worldwide, and over 300 of those can be found in North America. Changing climate conditions pose challenges for many migratory birds and their responses to these challenges can depend on their biology. To illustrate these impacts, a board game, called Migration Mismatch, was developed to help elementary school students understand...

Phenology, or the timing of the annual cycles of plants and animals, is extremely sensitive to changes in climate. We know that plants and animals may adjust the timing of certain phenological events, such as tree flowering or migration, based on changes in weather. However, it’s important that we also understand how the timing of phenological events is changing over longer time frames...

Invasive plants are a major land management problem in the Western U.S. Cheatgrass (Bromus tectorum) is the most prominent and problematic invader in cold deserts, with negative effects on rangeland fire patterns, wildlife habitats, and forage/vegetation. Red brome (B. madritensis) is an invader in the Mojave Desert, and can similarly introduce a new fire patterns to sensitive warm...

Climate change influences apex predators in complex ways, due to their important trophic position, capacity for resource plasticity, and sensitivity to numerous anthropogenic stressors. Bald eagles, an ecologically and culturally significant apex predator, congregate seasonally in high densities on salmon spawning rivers across the Pacific Northwest. One of the largest eagle...

In many places around the world, spring events, like warming temperatures, are coming earlier and fall events are coming later than they have in the past. These changes have implications for the phenology, or the timing of natural life events (e.g. the timing of plant flowering in Spring or leaves falling in Autumn), of many plant species. However, not all species and regions are...

Alaska’s Arctic Coastal Plain (ACP) and Yukon-Kuskokwim Delta (YKD) provide essential habitat for wildlife of management interest, including diverse communities of shorebirds and waterfowl. The low-lying ACP region is located on the North Slope of Alaska, and is rich with shallow lakes and ponds that form as a result of permafrost freeze-thaw cycles. This region is a primary nesting site...

Many inland waters across the United States are experiencing warming water temperatures. The impacts of this warming on aquatic ecosystems are significant in many areas, causing problems for fisheries management, as many economically and ecologically important fish species are experiencing range shifts and population declines. Fisheries and natural resource managers need timely and...

The stream systems of Hawai‘i are unique and home to many rare species, including five native fish and five native shellfish. These native species have amphidromous life cycles, meaning that they spend part of their lives in the ocean and part in freshwater streams. Stream flow serves as a vital natural pathway, connecting saltwater and freshwater habitats so that these animals can...
