Does the survival of threatened species indicate a flaw in the top predator hypothesis? The alternative is that the presence and ecological functioning of dingoes have gone unnoticed.
Type of Study:
correlation with no pre-determined gradient or contrast
Both of the threatened species surveyed in this study were found to survive in association with dingoes. The results of this study support the top predator hypothesis prediction that species at risk from predation and competition will only survive in the presence of a top-order predator.
dingo fence; close to dingo fence, deep inside fence
Dingo can provide conservation benefit to larger threatened species.
