Landscape drivers of genomic diversity and divergence in woodland Eucalyptus.

ABSTRACT: Spatial genetic patterns are influenced by numerous factors, and they can vary even among coexisting, closely related species due to differences in dispersal and selection. Eucalyptus (L'Héritier 1789; the "eucalypts") are foundation tree species that provide essential habitat and modulate ecosystem services throughout Australia. Here we present a study of landscape genomic variation in two woodland eucalypt species, using whole-genome sequencing of 388 individuals of Eucalyptus albens and Eucalyptus sideroxylon. We found exceptionally high genetic diversity (π ≈ 0.05) and low genome-wide, interspecific differentiation (F_ST  = 0.15) and intraspecific differentiation between localities (F_ST  ≈ 0.01-0.02). We found no support for strong, discrete population structure, b
