Demise of the dingo

Johnson C. N., Isaac J. L. & Fisher D. O. (2007) Rarity of a top predator triggers continent-wide collapse of mammal prey: dingoes and marsupials in Australia. Proceedings of the Royal Society B: Biological Sciences 274, 341-6.

Aim: 
Investigate if suppression of dingoes could have contributed to high rates of extinction of native mammals by allowing the intensity of predation from foxes and cats to increase.
Type of Study: 
Pre-existing contrasts
Key Results: 
Where ground-dwelling marsupials overlaped with dingoes, dingoes were a significantfactor that acted to them from decline and extinction.
Treatments: 
Overlap with dingo, overlapwith introduced herbivores (sheep & rabbit), overlap withfox, and overlap with dingo & overlap with sheep.
Response: 
The dingo is a keystone species protecting mammal biodiversity inAustralia and is the most significant constraint on the destructive power of exotic predators.
Models: 
Model selection
Reviewer:

Locations: 
Australia, excluding Tas.
Response variable : 
‘persistence’ = present range, as a proportion of the original range at European arrival.
Replication: 
137 taxa
Ecosystem: 
Australia-wide
