TL;DR: It is shown that the functional extinction of large-gape seed dispersers in the Brazilian Atlantic forest is associated with the consistent reduction of the seed size of a keystone palm species.

TL;DR: The objective of this review is to synthesize the existing literature concerning the influence of earthworms on the structure and function of soil microbial communities, as well as to understand how earthworm-induced changes in the soil microbiota would in turn impact soil processes, particularly those occurring in the rhizosphere and involved in plant growth and health.

TL;DR: This study showed that both megafrugivores play complementary rather than redundant roles as seed dispersers, and although tapirs disperse fewer seeds and species than muriquis, they disperse larger-seeded species and in places not used by primates.

TL;DR: The results found that defaunation leads to changes in the seed predator communities with potential consequences for plant–animal interactions.

TL;DR: Changes in dung beetle communities across a gradient of selective defaunation in continuous Brazilian Atlantic rain forest are described and the importance of the composition of mammal communities in structuring dung beetles communities is demonstrated.
