TL;DR: Patterns of reproductive isolation between species may provide insight into the mechanisms and evolution of barriers to interspecific gene exchange, and have important implications for the dynamics of hybrid zones, the direction of genetic introgression and the probability of reinforcement.

TL;DR: Results suggest that changes in ploidy disrupt a simple monotonic relationship between isolation and genetic distance in Silene, and find no evidence for the operation of speciation via reinforcement.

TL;DR: Host genotype-specific fungal communities may be present in the tree systemically, and persist in the host even after two clonal reproductions, and suggest that there is a functional basis for the strong biotic interaction.

TL;DR: The results show that detecting local adaptation is sensitive to the analytical approaches used and that model-based significance thresholds should be viewed with caution.

TL;DR: Examination of the effect of host relocation and high‐latitude warming on the complex fungal endophytic microbiome associated with leaves of an ecologically dominant boreal forest tree suggests that climate change effects on host–microbiome systems may be mediated by the interaction of environmental factors and the population genetic processes of the hosts.
