Correlations, dependency bounds and extinction risks Original Research Article

Methods for estimating bounds on extinction risks are described for cases where correlations among the parameters in a quantitative population viability analysis are unknown, and more generally where the forms of statistical dependence among the modelʹs parameters are unknown. An example using Leadbeaterʹs possum Gymnobelideus leadbeateri shows that making incorrect assumptions about correlations and dependencies may lead to severe over-estimation or under-estimation of extinction risks.
