If sharks habitats aren't known, it's harder to conserve either the animals or those habitats.
Marine mammals are often referred to as sentinels of the ocean and research on whales and dolphins in particular contributes important knowledge about the health of our seas.
Dingoes and wolves can help control destructive smaller predators, new research shows, but only if we encourage them across wide areas.
Carnivorous predators play an important, and until now unknown, role in preserving plant populations in the territories they inhabit.
Declining numbers mean the continent's top predator isn't fulfilling its ecological role.
