the supplementary materials for the article "collapse of the world’s largest herbivores" include figures and tables that provide additional data and analysis. figure s1 shows regional patterns of endangerment of large herbivores. figure s2 shows the number of published scientific articles by species. figure s3 compares pleistocene extinctions by body mass with current threatened species by body mass. figure s4 shows the global distribution of the four main threats faced by large herbivores. figure s5 shows human population trends and projections by region and ruminant livestock trends by region. figure s6 shows current range maps for the 72 large herbivores not classified as extinct in the wild. tables s1-s5 provide data on the 74 large terrestrial herbivores above 100 kg, the number of large herbivores in each ecoregion, and a summary of research effort from 1965 to june 2014. the data on the conservation status of species comes from the iucn red list, with some species having last been assessed as far back as 2008. the data on population trends and estimated sizes also come from the iucn red list. the masses of the species are obtained from pantheria and the animal diversity web. regions are based on the countries where each species is native according to the red list, with some exceptions. the tables also include information on the number of large herbivores facing each of the four main threats in each ecoregion. the research effort data is based on published articles from thomson reuters' web of science, using specific research categories. the data should be used for relative comparisons, as it does not reflect gray literature or other difficult to obtain publications. the figures and tables provide a comprehensive overview of the endangerment and distribution of large herbivores, as well as the threats they face and the research efforts dedicated to their study.the supplementary materials for the article "collapse of the world’s largest herbivores" include figures and tables that provide additional data and analysis. figure s1 shows regional patterns of endangerment of large herbivores. figure s2 shows the number of published scientific articles by species. figure s3 compares pleistocene extinctions by body mass with current threatened species by body mass. figure s4 shows the global distribution of the four main threats faced by large herbivores. figure s5 shows human population trends and projections by region and ruminant livestock trends by region. figure s6 shows current range maps for the 72 large herbivores not classified as extinct in the wild. tables s1-s5 provide data on the 74 large terrestrial herbivores above 100 kg, the number of large herbivores in each ecoregion, and a summary of research effort from 1965 to june 2014. the data on the conservation status of species comes from the iucn red list, with some species having last been assessed as far back as 2008. the data on population trends and estimated sizes also come from the iucn red list. the masses of the species are obtained from pantheria and the animal diversity web. regions are based on the countries where each species is native according to the red list, with some exceptions. the tables also include information on the number of large herbivores facing each of the four main threats in each ecoregion. the research effort data is based on published articles from thomson reuters' web of science, using specific research categories. the data should be used for relative comparisons, as it does not reflect gray literature or other difficult to obtain publications. the figures and tables provide a comprehensive overview of the endangerment and distribution of large herbivores, as well as the threats they face and the research efforts dedicated to their study.
