Life history strategies of stream fishes linked to predictors of hydrologic stability.

Life history theory provides a framework to understand environmental change based on species strategies for survival and reproduction under stable, cyclical, or stochastic environmental conditions. We evaluated environmental predictors of fish life history strategies in 20 streams intersecting a national park within the Potomac River basin in eastern North America. We sampled stream sites during 2018-2019 and collected 3801 individuals representing 51 species within 10 taxonomic families.
