This study analyzes ancient U/V sex chromosomes in Polytrichaceae mosses, showing that recombination suppression has limited SDR expansion and functional degeneration despite their 124 million-year-old origin.

The paper identifies genomic islands of parallel differentiation in the European flat oyster, showing they act as barriers to gene flow despite overall rampant gene flow.

The paper finds that genetic exchange is more frequent between animal species than plant species at the same level of genetic divergence, suggesting faster establishment of species barriers in plants.

This paper derives an expression for effective migration rate under polygenic local adaptation and shows how dominance and genetic architecture affect barriers to gene flow.
