Differential tree species response to a changing climate could serve to drive changes in tree species dominance that alter forest ecosystem dynamics and have cascading socio-ecological impacts. This study projected climate change–driven shifts in tree species dominance across Canada’s forests by the end of the twenty-first century. To do this, we mapped predictions of dominant tree species under possible future climate conditi...

A major goal of speciation research is identifying loci that underpin barriers to gene flow. Population genomics takes a ‘bottom‐up’ approach, scanning the genome for molecular signatures of processes that drive or maintain divergence. However, interpreting the ‘genomic landscape’ of speciation is complicated, because genome scans conflate multiple processes, most of which are not informative about gene flow. However, studying...
