The smallmouth bass (SMB) is a widespread species with a distribution that extends throughout the eastern and central U.S., in addition to introduced populations in other regions. From a management perspective, the SMB is important both as a popular sport fish and as a threat to native species where it is present outside of its natural range. Understanding the population-level responses of this species to environmental change is thus a priority for fisheries resource managers. This project aimed to explicitly model the impacts of projected climate and land use change on the growth, population dynamics, and distribution of stream-dwelling SMB in the U.S. Impacts on growth and demographic variables were modeled using...
Recent extreme floods on the Mississippi and Missouri Rivers have motivated expansion of floodplain conservation lands. Within Missouri there are more than 85,000 acres of public conservation lands in large-river floodplains. Floodplain lands are highly dynamic and challenging to manage, particularly as future climatic conditions may be highly variable. These lands have the potential to provide valuable ecosystem services like provision of habitat, nutrient processing, carbon sequestration, and flood-water storage that produce economic values in terms of recreational spending, improved water quality, and decreased flood hazards. However, floodplain managers may need tools to help them understand nonstationary conditions...
Human impacts occurring throughout the Northeast and Midwest United States, including urbanization, agriculture, and dams, have multiple effects on the region’s streams which support economically valuable stream fishes. Changes in climate are expected to lead to additional impacts in stream habitats and fish assemblages in multiple ways, including changing stream water temperatures. To manage streams for current impacts and future changes, managers need region-wide information for decision-making and developing proactive management strategies. Our project met that need by integrating results of a current condition assessment of stream habitats based on fish response to human land use, water quality impairment,...
Changes in the Earth’s climate are expected to impact freshwater habitats around the world by altering water temperatures, water levels, and streamflow. These changes will have consequences for inland fish – those found within lakes, rivers, streams, canals, reservoirs, and other landlocked waters – which are important for food, commerce, and recreation around the world. According to the U.S. Fish and Wildlife Service, in 2011, 33.1 million people fished and spent $41.8 billion in the United States alone. Yet to date, little comprehensive research has been conducted to investigate the effects of climate change on inland fisheries at a large scale. The aim of this project was to summarize the current state of...
They came from as far southeast as the Florida Keys and as far northwest as Fairbanks, Alaska, as a congregation normally separated by physical distance, but united by one growing concern: to find ways to help lessen the effects of climate change upon North American fish and fisheries. From June 1-5, a diverse collection of 27 fish experts (plus two remote attendees) representing a wide gamut of sectors, including the U.S. Geological Survey (USGS), universities, conversation agencies and state natural resource departments from both the U.S. and Canada converged in Bozeman, Mont., at the Northern Rocky Mountain Science Center for a workshop under the working title of “The Effects of Climate Change on Fish and Fisheries”...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact
