Story summary
- The study analyzed trophic diversity and dissimilarity of soil animals across 456 sites in 19 countries, spanning subarctic to tropical regions.
- Researchers used the SIBER package to calculate SEAc and applied linear mixed-effects models and random forests to identify climate, soil, and vegetation drivers.
- Isotope measurements for carbon and nitrogen were calibrated against international standards to ensure accuracy, and the dataset is limited in global representation, particularly in tropical regions.
