Fish and Climate Change (FiCli) Database: Informing climate change adaptation and management actions for freshwater fishes
Inland fishes provide important ecosystem services to communities worldwide and are especially vulnerable to the impacts of climate change. Fish respond to climate change in diverse and nuanced ways, which creates challenges for practitioners of fish conservation, climate change adaptation, and management. Although climate change is known to affect fish globally, a comprehensive online, public...
Fish Habitat Restoration to Promote Adaptation: Resilience of Sport Fish in Lakes of the Upper Midwest
Many Midwestern lakes are experiencing warming water temperatures as a result of climate change. In general, this change is causing coldwater fish species such as cisco and coolwater species such as walleye to decline. Meanwhile, warmer water species such as largemouth and smallmouth bass are increasing as temperatures warm. However, some fish populations are more vulnerable to these changes...
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,...
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...
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-...
Improving National Estimates of Inland Recreational Harvest Using State Angler Survey Data
Recreational fishing dominates inland fisheries in the United States. In 2016 alone, more than 30.1 million Americans identified as freshwater anglers and spent nearly $30 billion on freshwater fishing trips. While recreational freshwater fishing can be catch-and-release, a large portion is consumptive. In fact, evidence suggests that recreational fisheries yield more than ten times that of...
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....
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. The Northern Rockies are also experiencing rapidly...
Understanding Species' Range Shifts in Response to Climate Change: Results from a Systematic National Review
Climate change represents one of the foremost drivers of ecological change, yet its documented impacts on biodiversity remain uncertain and complex. Although there have been many published studies on species shifting their geographic ranges in response to climate change, it is still challenging to identify the specific mechanisms and conditions that facilitate range shifts in some species and...
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...
Making an Invisible Resource Visible: Integrating Inland Fisheries into the Sustainable Development Goals
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 of...
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...
Do empirical observations support commonly-held climate change range shift hypotheses? A systematic review protocol
Background Among the most widely anticipated climate-related impacts to biodiversity are geographic range shifts, whereby species shift their spatial distribution in response to changing climate conditions. In particular, a series of commonly articulated hypotheses have emerged: species are expected to shift their distributions to higher...

Despite their limited spatial extent, freshwater ecosystems host remarkable biodiversity, including one-third of all vertebrate species. This biodiversity is declining dramatically: Globally, wetlands are vanishing three times faster than forests, and freshwater vertebrate populations have fallen more than twice as steeply as terrestrial or marine...

Irrigated agriculture and inland fisheries both make important contributions to food security, nutrition, livelihoods, and well-being. Typically, in modern irrigation systems, these components operate independently. Some practices, commonly associated with water use and intensification of crop production, can be in direct conflict with and have...
