Bees travelling south: climate-induced range shifts and suitable habitat losses in south-eastern neotropics

Aim: Provide an assessment of climate change impacts on a set of wild pollinators restricted to one of the regions with the greatest diversity of bees in the world. Also, we aimed to test whether functional groups responded differently to climate projections.
Location: South-eastern South America (SES).
Taxon: Bees (Hymenoptera: Apidae sensu lato)
Methods: We selected 18 species of bees mostly restricted to the SES region, modelled their distributions and assessed the possible impacts of near future (2050) climate change in species richness and shifts in range centroids. Potential impacts related to different functional groups were evaluated through t-tests.
Results: SES species richness were projected to decrease in the northernmost regions and increase southward. Most bee species were predicted to shift their range centroids towards the south-west and south, while suitable stable areas were found in southern Brazil. We also found higher proportional losses in suitable areas for eusoci..., We selected 18 species of bees mostly restricted to the SES region, modelled their distributions and assessed the possible impacts of near future (2050) climate change in species richness and shifts in range centroids.

Here, we provide all the occurrence data and files to carry out all the modeling processes. Unfortunately, we cannot upload the WorldClim layers due to storage limits. However, we’ve provided all the necessary steps for bioclimatic variables preparation in the R code files.

### In detail here you will find:

* All occurrences data for each bee species as separated .csv files **(Data/occurrences/)**;
* Complete dataset with references for each record **(Occurrence-data-with-references/Occurrence-data-with-references.xlsx)**;
* R code for data preparation and creation of subdirectories for each species, following the structure required in ‘kuenm’ package **(01_data_preparation_and_folders_for_species.R)**;
* Folder with subdirectories for each species **(kuenm_bees/)**, created after running **01...
