Invasive Species Distribution Modeling in Hawaii
A series of scripts to model global, regional, and local distributions of species using the R Statistcal Programming Software with the purpose to identify areas in Hawaii most vulnerable to invasive speces (see HOWTO_DIY file for instructions)
ABOUT THE SCRIPTS:
sample of source code that runs all other scripts with various input variables based on IS_sample_data.zip file
0_source_script_MASTER.R more recent main interface with user selections to run species distribution models
0_source_script_MASTER_globalrun.R example for selected inputs for global runs
0_source_script_MASTER_localrun.R example for selected inputs for local runs
BIOMOD2 invasive species data formatting, options, modeling, and evaluation
tables to save model fitting outputs of evaluation scores and variable importance values
graphs of model fitting evaluation scores and variable importance values
variable importance by model type per species
ensemble model creation from model fitting outputs
response curve graphs from ensemble models
NOTE: there is no "2b" script
response curve graphs for mean ensemble per model type and species
projections of species distributions from fitted models and created ensembles
modification to run for proper ensemble model projections
creation of rasters (tiff) files and images of mapped species distributions
map creation of climate envelop showing areas with same climatic conditions
calculation of species range shifts from baseline to future runs
mapped species distribution from ensembles showing change in scenarios
short code for temporary files to be deleted to free up space and memory if needed
