A Synthesis of Recent Links Between Climate Change and Ecosystem Services Supply and Demand

Climate change is already affecting and will continue to impact the supply and demand of ecosystem goods and serivces (EGS) that are important for human well-being. Therefore, it is important to monitor trends and identify gaps in how climate change is incorporated into the assessment and management of these services. Systematic literature reviews play an important role in this process. For exampl

Assessing the State of Global Inland Fisheries

The Food and Agriculture Organization of the United Nations (FAO) documents the status and trends of marine fish stocks that represent approximately 80% of global marine catch. These stocks are routinely monitored, and the FAO assessment describes the extent of exploitation against different reference points - such as underfished, sustainable fished, or overfished. Although inland fisheries, which

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

Developing and Testing a Rapid Assessment Method for Understanding Key Social Factors of Ecological Drought Preparedness

Drought is a complex environmental hazard that impacts both ecological and social systems. Accounting for the role of human attitudes, institutions, and societal values in drought planning is important to help identify how various drought durations and severity may differentially affect social resilience to adequately respond to and manage drought impacts. While there have been successful past eff

Estimating Global River Fisheries Harvest Potential

Fish that are harvested from rivers and lakes play an important role in ensuring global food security. However, data on river fisheries is not collected in any standardized format globally. Although targeted analyses have been conducted on certain river systems, the approaches used, such as intensive field sampling, are not feasible at a global scale. Most river fish are harvested by small-scale o

Examining Linguistic Diversity Metrics in Intergovernmental Ecosystem Assessments

Multicultural representation is a stated goal of many global scientific assessment processes. These processes aim to mobilize a broader, more diverse knowledge base and increase legitimacy and inclusiveness of these assessment processes. Often, enhancing cultural diversity is encouraged through involvement of diverse expert teams and sources of knowledge in different languages. This project examin

State of the Science on Ecosystem Transformation

Recent changes in climate are having profound effects on many fish and wildlife species, and projections suggest that those trends are likely to continue. Changing climate conditions have the potential to transform ecosystems, which impacts not only fish and wildlife but also human communities, which rely on ecosystems for important goods and services such as food and water filtration.

Synthesizing Climate Change Impacts on Wildlife Health and Identifying Adaptation Strategies

Changing climate conditions could have significant impacts on wildlife health. Shifts in temperature and precipitation may directly affect the occurrence of disease in fish and wildlife by altering their interactions with pathogens (such as the bacterium that causes Lyme disease), helping vectors like mosquitoes and ticks expand their range, or speeding up the time it takes for a parasite to devel

The U.S. Inland Creel and Angler Survey Catalog (CreelCat): A Database and Interactive Tool for Inland Fisheries Management and Research

Inland recreational fishing, defined as primarily leisure-driven fishing in freshwaters, is a popular past-time in the USA. State natural resource agencies endeavor to provide high-quality and sustainable fishing opportunities for anglers. Managers often use creel and other angler-survey data to inform state- and waterbody-level management efforts. Despite the broad implementation of angler survey

Understanding Climate Impacts on Native and Invasive Fish for Conservation, Management, and Economic Goals in the Northern Rockies

As the origin of three major basins that drain the Columbia, Missouri, and Saskatchewan rivers, Montana is the hydrologic apex for North America. The Northern Rocky Mountain region is home to some of the last remaining interconnected habitats for many native fishes, including the threatened bull trout and native westslope cutthroat trout.
