Table 1 Input parameter sets and outputs of demogenetic simulations and variable importance (%incMSE) and rank (from highest to lowest variable importance) for 5 separate RF metamodels with input parameters as independent variables and outputs as dependent variables. Simulations carried out in a three-patch landscape with “source” and “arrival” breeding habitat patches separated by a “connectivity” patch with varying amounts of ‘dispersal habitat’ and varying ‘degrees of fragmentation’ (i.e. from 1 for randomly distributed dispersal habitat to 4 for large blocks of continuous dispersal habitat), for 3 different movement syndromes (MS 1: shy, MS 2: intermediate, MS 3: bold) and 3 sizes of the founder population

From: The boon and bane of boldness: movement syndrome as saviour and sink for population genetic diversity
