Summary of the 84 case studies, from 65 papers, found using ISI Web of Science that examined the effects of carrion on five different ecological categories between 1990 and 2010. Some studies examined multiple categories (e.g. soil nutrients and plant responses). 1 Barton, Cunningham, Lindenmayer, Manning. (2012).

Summary of carrion arthropod studies across five major habitat types using different animal carrion models. ‘Farmland’ included modified production landscapes; ‘Forest’ included forest and woodland environments; ‘Grassland’ included prairie and savannah environments; ‘Urban’ included built environments; ‘Arid’ included desert and semi-arid environments. ‘Small carcasses’ = fish, rodents, rabbits or birds; ‘Large carcasses’ = ungulates or large vertebrates. ‘Multiple types’ = two or more different animal carcasses. Some studies contributed to more than one category (e.g. compared arthropods at rodent and rabbit carcasses in farmland and nearby forest). All studies presented empirical data on the response of arthropods to carrion between 1990 and 2010. List of studies are shown in Table S4. 2 Barton, Cunningham, Lindenmayer, Manning. (2012).

Summary of arthropod studies that included a spatial or temporal contrast, and focused on a particular arthropod group. ‘Habitats’ included spatial environmental comparisons; ‘Seasons’ included within or between year comparisons; ‘Carcass types’ included comparisons of carrion from different animal species; ‘None’ included studies with no spatial or temporal contrast. Some studies contributed to more than one category (e.g. compared coleopteran communities in different habitats at different times of the year). All studies presented empirical data on the response of arthropods to carrion between 1990 and 2010. List of studies are shown in Table S4. 3 Barton, Cunningham, Lindenmayer, Manning. (2012).
