Climate Adaptation Science Centers
From wildfires to sea-level rise, climate change creates evolving challenges for ecosystems across the nation. The USGS National and Regional Climate Adaptation Science Centers (CASCs) is a partnership-driven program that teams scientists with natural resource managers and communities to help fish, wildlife, water, land, and people adapt to a changing climate.
The CASCs

Evaluating the central–marginal hypothesis: Introgression and genetic variation at the trailing edge of Quercus bicolor Evaluating the central–marginal hypothesis: Introgression and genetic variation at the trailing edge of Quercus bicolor
The central–marginal hypothesis (CMH) predicts reduced genetic diversity and increased differentiation in range-edge populations due to ecological marginality and limited gene flow. Deviations from this pattern, however, can result from historical demographic processes, variation in reproductive strategies or interspecific hybridization. The genus Quercus, known for hybridization and...
Global recreational consumption of non-native inland fish: Higher economic benefits, but lower nutritional value and climate resilience Global recreational consumption of non-native inland fish: Higher economic benefits, but lower nutritional value and climate resilience
Inland recreational fisheries are globally significant leisure pursuits, with well-documented benefits to human health and well-being, but also one of the principal drivers of non-native fish introductions to enhance fishing opportunities, whether for sport or sustenance. In this study, we assess the relative reliance of global inland recreational fisheries on non-native versus native...
Insight 4. Climate change and biodiversity loss amplify each other Insight 4. Climate change and biodiversity loss amplify each other
Key messages: • Climate change is impacting biodiversity from local to global scales, and growing evidence suggests that further loss of biodiversity can contribute to climate change, creating a destabilizing feedback. • Loss of plant diversity due to climate and land-use change can weaken ecosystem functioning, leading to a decrease in biomass accumulation and reduced carbon storage. •...
