Small native mammals eat more plant seeds than had been realised, and their loss to predators such as foxes and feral cats has likely caused significant changes to vegetation in outback Australia.

Présentation
Small native mammals including bettongs are much bigger consumers of plant seeds than had been realised, and their loss due to predation by foxes and feral cats has likely caused significant changes to vegetation in outback Australia, UNSW Sydney research shows. _ The study is published in the journal Functional Ecology. It was conducted in central Australia at two desert sites where small native mammals have been re-introduced into predator-free exclosures – the Arid Recovery Reserve in South Australia and the Scotia Wildlife Sanctuary in south-western NSW.
Photographs and other evidence such as footprints and droppings confirmed that mammals were active around the seed trays. Surveys also revealed there were fewer woody shrub seedlings in rewilded areas compared with areas outside the exclosures.
