1. Introduction. Understanding the dynamics governing the founding of new populations is a central focus of evolutionary biology [1-3] and has clear application in conservation, restoration, biological control and invasion biology [4-6].The most consistent predictor of successful colonization is the number of individuals founding a population [7,8].Small founding populations face extinction due to demographic stochasticity and Allee effects, and we can derive, from simple population models, the expected relationship …A census founding population of between 1,300 and 1,550 individuals was necessary to maintain a quasi- extinction threshold of ≲0.1.
