Drosera Species Climate Impact

This repository contains the occurrence data and source code used in our research on the impacts of climate change on the distribution of Drosera species. Our study aims to understand how changing climatic conditions affect these unique carnivorous plants and to assess potential risks to their future distribution.

Contents

• Occurrence Data: Raw data collected on the occurrence of Drosera species across different geographic locations.
• Source Code: Python and R scripts used for data cleaning, bioclimatic variable selection, and model calibration.

Details

1. Cleaning and Preparing Occurrence Data

• Script: data_cleaning.py
• Description: Processes the raw occurrence data, removing duplicates and filtering out records with missing or erroneous information. Prepares the dataset for further analysis.

2. Selecting and Cropping Bioclimatic Variables

• Script: bioclim_variables.R
• Description: Selects relevant bioclimatic variables from WorldClim and other climatic databases. Crops these variables to the study area, matching the geographic extent of the occurrence data.

3. Calibrating Models, Extrapolation, and Risk Assessment

• Script: model_calibration.py
• Description: Calibrates species distribution models using the cleaned occurrence data and selected bioclimatic variables. Includes steps for model extrapolation to future climate scenarios and assessing risks to Drosera species distribution.

Usage

To use the scripts in this repository, ensure you have Python and R installed on your machine. Detailed instructions on how to run each script are provided within the script files themselves.

Data Sources

• Occurrence Data: Sourced from Global Biodiversity Information Facility (GBIF) and other public databases.
• Bioclimatic Variables: Obtained from WorldClim.
