A Framework to Integrate Innovations in Invasion Science for Proactive Management Invasive alien species (IAS) are a rising threat to biodiversity, national security, and regional economies, with impacts in the hundreds of billions of U.S. dollars annually. Proactive or predictive approaches guided by scientific knowledge are essential to keeping pace with growing impacts of invasions under climate change. Although the rapid development of diverse technologies and approaches has produced tools with the potential to greatly accelerate invasion research and management, innovation has far outpaced implementation and coordination. Technological and methodological syntheses are urgently needed to close the growing implementation gap and facilitate interdisciplinary collaboration and synergy among... Categories: Publication; Types: Citation Assessing the Vulnerability of Native Trout in the Northern Rockies: Linking Science and Management for Climate Adaptation Trout are one of the most culturally, economically, and ecologically important groups of freshwater fishes in the Rocky Mountain region. However, human impacts and climate change are significantly altering freshwater ecosystems that support native trout species. Despite their broad importance, many of the region’s trout populations are threatened and some require immediate conservation efforts to reverse their decline. Although work is being done to understand and mitigate these changes, the ability to accurately assess vulnerability is currently limited due to a lack of data-driven approaches that incorporate uncertainty and adaptive capacity at scales relevant to effective management. USGS researchers will...

Extreme droughts reduced streamflows and increased water temperatures, causing stressful conditions for trout and numerous fishing site closures. This resulted in anglers moving to find fishing locations that were more favorable to trout during extreme drought conditions. By moving to fishing locations that were more favorable during drought, visitors kept trout fishing revenue in the state rather than choosing to travel elsewhere. This flexibility revealed surprising resiliency... Categories: Publication; Types: Citation Final Report: Predicting Climate-Induced Expansions of Invasive Fish in the Pacific Northwest: Implications for Climate Adaptation of Native Salmon and Trout Climate change and invasive species are major threats to native biodiversity, but few studies have examined their combined effects at large spatial and temporal scales. Using 21,917 surveys collected over 30 years, we quantified the impacts of climate change on the past and future distributions of five interacting native and invasive trout species throughout the northern Rocky Mountains, USA. We found that the occupancy of native bull trout and cutthroat trout declined by 18% and 6%, respectively, from 1993 to 2018 and was predicted to decrease by an additional 39% and 16% by 2080. However, reasons for the occupancy reductions differed markedly across species; increasing water temperature and decreasing streamflow... Categories: Publication; Types: Citation Socioeconomic resilience to climatic extremes in a freshwater fishery Abstract (from Science Advances): Heterogeneity is a central feature of ecosystem resilience, but how this translates to socioeconomic resilience depends on people’s ability to track shifting resources in space and time. Here, we quantify how climatic extremes have influenced how people (fishers) track economically valuable ecosystem services (fishing opportunities) across a range of spatial scales in rivers of the northern Rocky Mountains, USA, over the past three decades. Fishers opportunistically shifted from drought-sensitive to drought-resistant rivers during periods of low streamflows and warm temperatures. This adaptive behavior stabilized fishing pressure and expenditures by a factor of 2.6 at the scale... Categories: Publication; Types: Citation Climate change and expanding invasive species drive widespread declines of native trout in the northern Rocky Mountains, USA Climate change and invasive species are major threats to native biodiversity, but few empirical studies have examined their combined effects at large spatial and temporal scales. Using 21,917 surveys collected over 30 years, we quantified the impacts of climate change on the past and future distributions of five interacting native and invasive trout species throughout the northern Rocky Mountains, USA. We found that the occupancy of native bull trout and cutthroat trout declined by 18 and 6%, respectively (1993–2018), and was predicted to decrease by an additional 39 and 16% by 2080.
