The first worldwide study of animals and the seeds they eat has overturned a long-held assumption — that large animals mainly eat large seeds. The finding shows that a wider variety of plants than is often thought could be at risk if large animals go extinct and do not disperse their seeds. The study covers 13,000 animal-seed interactions and includes all vertebrate species — fish, amphibians, reptiles, birds and mammals — from areas ranging from the Arctic tundra to tropical rainforests.img src=»http://feeds.feedburner.com/~r/sciencedaily/~4/tQqcupQMoHc» height=»1″ width=»1″ alt=»»/
