Table S1 database effect sizes - (Mal)adaptation meta-analysis

The following keywords were used in our literature searches of conservation strategies: `assisted colonization`, `assisted migration`, `translocation`, `genetic rescue`, `evolutionary rescue`, `transgenerational plasticity`, `hybridi*ation AND outbreeding`, `hybridi*ation OR hybrid AND viability AND conservation`; (January 2018 using Web of Science or Google Scholar). To determine if an article had usable data on maladaptation, we used the following four criteria: (1) data must include a fitness metric, including survival, fecundity or egg/seed size, or abundance or recruitment; correlates of fitness such as growth or body size were rejected; (2) either data from a control without a conservation intervention (to measure relative fitness), or data from the population before conservation was implemented (to measure absolute fitness), must be available; (3) data from at least two different time periods after the conservation intervention must be available; (4) sample size, and a metric of sampling variance (standard error or deviation, or confidence intervals) for the fitness metrics must be reported. A total of 15 articles on a total of 15 species were selected based on these four criteria. The species covered a wide taxonomic breadth, including yeast, plants, invertebrate animals, and vertebrate animals. A total of 95 entries were included, with multiple entries from most studies. The type of conservation intervention (i.e., the conservation “strategy”) was gleaned from study abstracts. We also recorded whether the experimental conditions imposed were stressful (40 entries, experimental stress treatment, e.g., high salt or heat shock) or benign (55 entries, control treatment, e.g., low salt or no heat shock, or no implicit stress treatment imposed).
