title: Comprehensive spatial risk assessment using community-based species distribution models stratified by ant damage types

description: Global occurrence coordinates for 15 ant species, including Solenopsis invicta, Linepithema humile, Anoplolepis gracilipes, Wasmannia auropunctata, Pheidole megacephala, Acromyrmex octospinosus, Tapinoma melanocephalum, Monomorium destructor, Myrmica rubra, Solenopsis richteri, Brachyponera chinensis, Paratrechina longicornis, Monomorium pharaonis, Solenopsis geminata, and Technomyremex albipes, were obtained from the Global Biodiversity Information Facility (GBIF) to predict their potential distributions under climate change. The ant species were categorized into community groups based on the types of damage they could cause, including impacts on biodiversity, direct or indirect effects on agriculture, and threats to human health such as physical attacks and disease transmission. To reduce sampling bias and improve model performance, spatial filtering was conducted using ArcGIS.

Meteorological data were obtained from WorldClim (https://www.worldclim.org) at a 10-minute spatial resolution for the period 1992–2021, including average maximum and minimum temperatures and precipitation. These data were then converted into 19 bioclimatic variables using the biovars function in the dismo package of R software.

To assess the impact of climate change on future ant habitats, we considered two shared socioeconomic pathways (SSPs): SSP245 and SSP585. For both scenarios, we used the 19 bioclimatic variables at a 10-minute spatial resolution. Climate projections were derived from four global circulation models (GCMs)—ACCESS-CM2, MIROC6, MPI-ESM1-2-HR, and UKESM1-0-LL—sourced from WorldClim.

Global soil temperature data were obtained from a previous study (Lembrechts et al., 2022). The soil bioclimatic variables (SBio) represent global soil temperatures at a 30-arcsecond resolution and are available for two depth intervals: 0–5 cm and 5–15 cm. To match the resolution of the bioclimatic variables, soil temperature layers were interpolated using kriging to achieve a 10-minute resolution.

We used ENMeval in the R package to determine the model features and regularization multiplier (RM). We also additionally used R for random forest.
