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

Number of Founders: 10, 50, 100 [initial population size]

Movement syndrome: Shy (MS.1), intermediate (MS.2), bold (MS.3) [shy-bold continuum] respectively; Pmatrix =0.03, 0.06, 0.12; Pc =50, 50, 50; Pmaxmat =10, 20, 40

Amount of dispersal habitat: 0 (CS1), 10, 20, 30, 40, 60, 80, 100 (CS2) [%]

Degree of fragmentation: 1, 2, 3, 4 [random - clumped continuum]
