They are top predators and will take domestic animals as well as wild.
This has increased hunting when they occupy the same space as man. Agriculture is spreading increasing this threat. They need a large home range. This brings them more often into conflict with man. They also have a low reproductive rate. Island organisms can be particularly vulnerable to extinction.
Dependent on the size of the island populations tend to be small. Islands have a high degree of endemic species.
Barnosky and colleagues studied large animal extinctions that occurred between 50, and 10, years ago, an era called the late Pleistocene. These extinctions included animals such as mammoths and mastodons, the saber-toothed cat, ground sloths and native American horses and camels.
While many researchers have blamed humans for those extinctions, the team led by Barnosky, of the University of California, Berkeley, said humans and climate change share the blame. Climate change is occurring more rapidly today than in the late Pleistocene and growing human populations are taking over former large-animal habitats, Barnosky said.
