Fish abundance dataset Data corresponding to the analyses of juvenile (0+) salmon and trout abundance as a function of Ranunculus cover (%), explanatory variables describing the experimental design (Year, Month, Block), and explanatory variables representing site- and time-specific habitat characteristics of study sites (Water depth [cm], Proportion of Fast Velocities, Velocity Heterogeneity, Macroinvertebrate biomass [mg]). Fish site retention rate dataset Data corresponding to the analyses of juvenile (0+) salmon and trout site rentention rate (Recaptured fish caught in time t, Total fish tagged in time t-1) as a function of Ranunculus cover (%), explanatory variables describing the experimental design (Year, Period, Block), and explanatory variables representing site- and time-specific habitat characteristics of study sites, averaged across time period (Water depth [cm], Proportion of Fast Velocities, Velocity Heterogeneity, Macroinvertebrate biomass [mg]). Fish growth dataset Data corresponding to the analyses of change in weight (g) of individual juvenile (0+) salmon and trout as a function of Ranunculus cover (%), initial weight (g), and explanatory variables describing the experimental design (Year, Period, Block, Site). Macroinvertebrate biomass surber dataset Data corresponding to the analyses of macroinvertebrate biomass (sum) and average macroinvertebrate size (mean) in Surber samples as a function of Ranunculus cover (%) and explanatory variables describing the experimental design (Year, Month, Block, Site). Fish prey biomass dataset Data corresponding to the analyses of fish prey biomass (sum) and average fish prey size (mean) in individual fish diet contents as a function of Ranunculus cover (%), fish species (Salmon, Trout), individual fork length (cm), and explanatory variables describing the experimental design (Year, Month, Block, Site). Fish diet niche dataset Data corrresponding to the analysis of dietary niche overlap between salmon and trout in different Ranunculus cover levels using proportional abundance and proportional biomass of prey taxa in individual fish diet contents.
