Fig. 4: Disentangling the impact of inbreeding depression on population recovery in a broad demographic parameter space.
From: Inbreeding and demography interact to impact the recovery of a bottlenecked crested ibis population
The outcomes were drawn from simulations that started with a bottlenecked founder population of three pairs and a scenario where the clutch size was set to three eggs. The probability value in each cell was calculated based on 100 independent simulation replicates. The heatmaps in A and B show the probability of population restoration under broad ranges of juvenile and adult mortality rates when the effect of inbreeding depression is respectively absent (s0 = 0) or present (s0 = 1). The colour scale is consistent in both panels. C The net effect of inbreeding depression on the probability of population restoration. Each cell in the grid represents the restoration probability difference between the corresponding cells in (A) and the present (B). The white area presents a parameter space where restoration is not possible regardless of the presence or absence of inbreeding depression. The labelled dots I–III in the panels represent hypothetical species whose restoration probabilities are influenced by the combined effect of inbreeding depression and demographic parameters in different ways (see main text for details).
