This ZIP file contains two R files, three BUG files, and four Rsave files. These files contain the code and data used to fit and analyze the models described in the main text.
This is an R script that fits posterior distributions of parameters from data. This script uses the following BUG files: bayes_survival.bug, bayes_seed_production.bug, bayes_seedling_survival.bug. It also uses the raw data saved in the file: mordecai_data_sources.Rsave.
The script runs through Bayesian model fitting using MCMC for each of the parameters listed in Table A1, with specified priors and MCMC methods. It saves MCMC samples for further model analyses. It creates Figs. B1B11.
This is an R script containing all analyses of the parameterized population growth models. It uses the following data files: samps.Rsave, sensitivity.Rsave.
The script analyzes the parameterized population growth models by calculating growth rates when rare (GRWR) and performing sensitivity and uncertainty analyses. It creates Figs. 13 and B12B18.
