Extreme specificity in epiparasitic Monotropoideae (Ericaceae): widespread phylogenetic and geographical structure.

abstract：:Widespread species that exhibit both high gene flow and the capacity to occupy heterogeneous environments make excellent models for examining local selection processes along environmental gradients. Here we evaluate the influence of temperature and landscape variables on genetic connectivity and signatures of local ad...
