Assessing the Impact of Future Climate on Hawai‘i’s Aquatic Ecosystems

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 migrate between them and carry out critical life stages (e.g., development, reproduction). Over the last 20 years, the amount of rainfall in Hawai‘i has decreased, and climate models predict that this trend will continue. It is uncertain how reduced rainfall will affect stream flow and, consequently, the native stream species that depend...

Developing Adaptation Strategies for Recreational and Tribal Fisheries in the Upper Midwest

Fisheries in the glacial lakes region of the upper Midwest are culturally, economically, and recreationally beneficial. Walleye, for instance, represent an important subsistence food source for some Wisconsin tribal nations and are also popular among recreational anglers. However, predicted ecological changes to these aquatic communities, such as an increase in invasive fish species, a decrease in walleye and other native fishes, and worsening water quality due to increases in temperature and shifts in precipitation, has prompted concern among regional anglers who may abandon certain fisheries as these changes occur. Understanding how changes in climate may affect glacial lakes region fishes, and how fishery managers...

Impacts of Global Change on Biotic Resistance, Resilience, and Ecosystem Services in Caribbean Fish Assemblages, Fisheries, and Aquatic Ecosystems

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 communities in streams, rivers, and lakes may have the natural ability to resist the long-term impacts of extreme weather events. In this project, researchers will investigate the ability of Caribbean fish assemblages in Puerto Rico, which have both economic and cultural importance, to resist the impacts of extreme weather events....
