Table 2. Results of multiple matrix regression with
randomization (MMRR) testing for the relationships between population
genetic differentiation (FST) and explanatory variables
representing weighted topographic distance (isolation by distance,
IBDWTD), climatic dissimilarity (isolation by
environment, IBECLI) and alternative isolation by
resistance (IBR) scenarios. IBR scenarios consist of current and past
habitat suitability based on (i) only climatic variables
(*CurrentENV, and LGMENV), (ii)
climate-based habitat suitability maps for host species
(CurrentHOST, LGMHOST), and (iii)
combining climatic variables climate-based habitat suitability maps for
host species (*CurrentENV-HOST and
LGMENV-HOST). IBRNULL represents an IBR
scenario where all pixel values are equal to 1 (flat landscape). β,
regression coefficient; t , t -statistic; p ,
significance level.
