An invasive pathogen drives directional niche contractions in amphibians: supplementary

Attached are supplementary code and results data for the manuscript 'An invasive pathogen drives directional niche contractions in amphibians'. All occurrence data used in this manuscript are available from the sources cited within text. Code attached describes the methods used to calculate niche hypervolume, including alpha hull calculation ('Example_hypervolume_script.R'), calculation of beta diversity metrics ('beta-diversity-script.R'), and the basis of our BACI analysis (BACI-analysis.R). Attached CSV files display amalgamated results from the BACI analysis relating to beta diversity ('BACI_results_beta_diversity.csv') and niche shift ('BACI_results_niche_shift.csv'). The file 'all_records_extracted_values.csv' contains the raw extracted climatic and elevation values for each record, for each species. Each record is also designated as 'Contemporary' or 'Historical', denoting whether the occurrence was recorded pre- or post-chytrid fungus emergence.
