Please, refer to the publication for additional details:

Barbarossa, V., Bosmans, J., Wanders, N. et al. Threats of global warming to the world’s freshwater fishes. Nat Commun 12, 1701 (2021). https://doi.org/10.1038/s41467-021-21655-w

R Scripts

config.R/config_local.R: global parameters used in the R scripts
exec.R: generates batch file for streamlined execution to be run on a linux slurm cluster

Preprocessing

scripts/R/pre/pcrglobwb_hist.R: preprocess pcrglobwb historical runs to obtain one long-term layer
scripts/R/pre/pcrglobwb_fut.R: preprocess pcrglobwb future scenario runs to obtain one long-term layer at each warming target-RCP-GCM combination
scripts/R/preprocess/species2points.R: this script transforms the polygon ranges of the species to spatial points based on the resolution of the environmental variables, to use a matrix-like framework to model range changes
scripts/R/preprocess/species2points_dispersal.R: this script transforms the polygon ranges of the species to spatial points based on the resolution of the environmental variables, to use a matrix-like framework to model range changes

Modelling

scripts/R/map_thresholds.R: mapping of species-specific thresholds
scripts/R/model_occurrence.R: modelling of species-specific percentage of threatened range under no dispersal assumption
scripts/R/model_occurrence_dispersal.R: DEPRECATED
scripts/R/model_occurrence_dispersal2.R: modelling of species-specific percentage of threatened range under maximal dispersal assumption

Phyloenetic regression

scripts/R/res/phyloreg_stochastic_array.R: runs phylogenetic regression based on stochastically generated trees
scripts/R/res/phyloreg_stochastic.R: tabulates results of coefficients and variable importance for the phylogenetic regression as described in
scripts/R/res/phyloreg.R: DEPRECATED
scripts/R/res/phyloreg_array.R: DEPRECATED
scripts/R/res/phyloreg_explore.R: DEPRECATED

Extras

scripts/R/xtr/retrieve_habitat_iucn.R: uses the API from IUCN to retrieve info on species habitat
scripts/R/xtr/analyze_habitat_iucn.R: compiles info from retrieve_habitat_iucn into a table
scripts/R/xtr/calc_global_mean_air_temp.R: NEED TO CHECK IF THIS IS THE ONE USED IN THE FINAL MODEL
scripts/R/xtr/compile_species_ranges_dataset: merge datasets of fish ranges from IUCN, Barbarossa et al. 2020 (PNAS), AmazonFISH into one lobal dataset with polygon vertices based on a 5 arcmin grid
scripts/R/xtr/compile_traits.R: retrieve info on species' traits, range area, climate zone and compile them in a table
scripts/R/xtr/thresholds_selection.R: analyze thresholds mapped for the species and check multicollinearity
scripts/R/xtr/extract_climate_zones.R: assign a climate zone to each species
scripts/R/xtr/reference_species_ranges2hybas12.R: DEPRECATED

Functions

scripts/R/fun/generic.R: generic functions
scripts/R/fun/HighstatLibV10.R: function to calculate VIFs from Highland Statistics LTD
scripts/R/fun/map_variable2species.R: function to retrieve quantiles of an environmental variable for a species range
scripts/R/fun/range2table.R: function that convert polygon ranges to single spatial points
scripts/R/fun/variable_importance.R: function to calculate variable importance
