“Australasian bird invasions: accidents of history?"
Of the >242 species introduced by Europeans to Australasia during the 18th-20th centuries, at least 32% established long-term viable populations. A review of the literature reveals the most robust predictors of introduction success to be total number of individuals liberated, and the number of separate attempts at introduction. Using generalized linear modeling on a combined regional dataset, I confirm this result, and demonstrate that together these two characteristics of historical introductions correctly explains the observed outcome in 89.3% of cases in Australia.The entire paper can be downloaded here (.pdf).
