Functional Ecology. https://doi.org/10.1111/1365-2435.13973 Available files include: -R scripts used to: conduct Bayesian binomial generalized linear mixed models and construct Figures 1 and 2 (Resp_Survival_2017-2018_Sept2021.R), examine changes in juvenile body sizes prior to release (Metamorph_2017_Release_BodySize_Apr2021.R) and over the course of the study period (Phys_Surv_Change_Size_Apr2021.R), calculate the effect of relative apparent activity levels on juvenile survival to produce Figure 3 (Location_Known_Alive_Apr2021.R), and calculate selection coefficients (Selection-Coefficients_Sept2021.R). Scripts were developed and run using R version 4.0.0. -All necessary data files to run these R scripts and support the findings of our study (WVP_RSAWL_2017-2018_Survival.csv, Released_Rounds3-5_RSAWL_MINVCO2_2017.csv, abiotic.csv, Metamorph_2017_Release_Data.csv, Phys_Surv_Change_Size.csv, Location_KnownAlive.csv).
