Supplemental Document: Skill sets for a collaborative, simulation based study Landscape ecologists- determine appropriate environmental variables to include, parameterize and construct landscape resistance surfaces, create landscape input files Population ecologists- parameterize life history including variance in reproductive success, movement distributions, mortality rates, starting age structure, mating scheme Computational biologists- assist with choosing appropriate simulation software, create input files, arrange bioinformatics pipeline to create and analyze simulations and summarize results Statisticians- determine the appropriate number of simulations to run, appropriate sampling (populations, individuals, markers), and appropriate statistical tests Population geneticists- construct genetic marker input files (including mutation rates and potential genetic architecture of quantitative traits), contribute knowledge about migration rates and effective population size Resource management professionals/ policy officials- ensure that the questions being asked in the study are relevant, that the results will have high practical utility, and that potential interventions that are simulated are technically and economically feasible Social scientists, climatologists, physiologists, disease ecologists, economists- assist with connecting population simulation models to models of other relevant processes
