New Paper - No need for disease: testing extinction hypotheses for the thylacine using multi-species metamodels
A new paper involving Environment Institute members , (also SARDI), and as well as Christopher Johnson (University of Tasmania), Robert Lacy (Chicago Zoological Society) and John Pollak (Cornell University) has recently been published in the Journal of Animal Ecology.
The paper titled designed a new population viability approach (PVA) that includes species interactions explicitly by networking species models within a single ‘metamodel’.

Population viability analysis (PVA) is used to assess the extinction risk of threatened species and to evaluate different management strategies. However, conventional PVA neglects important biotic interactions and therefore can fail to identify important threatening processes.
This study demonstrates the utility of PVA metamodels by using them to reinterpret the extinction of the carnivorous, marsupial thylacine Thylacinus cynocephalus (Tasmanian Tiger) in Tasmania. In particular, they test the claim that well-documented impacts of European settlement cannot account for this extinction and that an unknown disease must have been an additional and necessary cause.
