Summary:
A new article by a UNSW Sydney-led team
challenges the validity of current methods for forecasting the persistence of
slow-growing species for conservation purposes, and provides a better approach
to reducing the threat of extinction.
Previous research on wild dolphins in
Australia and wild bears in North America has revealed that reproductive
success is the best predictor of the viability of these long-lived populations,
rather than their survival rates.
The findings of these and other studies fly
in the face of decades of population modelling, which has led to a widespread
generalisation that survival is the most important factor for population
viability of long-lived species, the researchers say.
