The supplementary materials for the article "Collapse of the World’s Largest Herbivores" provide detailed regional patterns and data on the endangerment status of large herbivores. The PDF includes figures and tables that illustrate: 1. **Regional Patterns of Endangerment (Fig. S1)**: Shows the distribution of endangered large herbivores across different regions, including Africa, Southeast Asia, Asia, India, China, Europe, Latin America, and North America. 2. **Table S2 and Table S3**: Provide the number of large herbivores (threatened and total) found in each ecoregion, focusing on 30 ecoregions with at least five threatened species. 3. **Table S4**: Lists the specific threatened large herbivores in each ecoregion. 4. **Table S5**: Summarizes research effort from 1965 to June 2014, detailing the number of published articles on various aspects of large herbivores. 5. **Fig. S2**: Displays the number of published scientific articles by species, with threatened species marked. 6. **Fig. S3**: Compares Pleistocene extinctions by body mass with current threatened species by body mass. 7. **Fig. S4**: Shows the global distribution of the four main threats faced by large herbivores. 8. **Fig. S5**: presents human population trends and ruminant livestock trends by region. 9. **Fig. S6**: Provides current range maps for 72 large herbivores not classified as extinct in the wild, noting potential fragmentation and errors in species range boundaries. These materials offer comprehensive insights into the conservation status and threats faced by large herbivores globally.The supplementary materials for the article "Collapse of the World’s Largest Herbivores" provide detailed regional patterns and data on the endangerment status of large herbivores.
