Host-associated genetic differentiation in the face of ongoing gene flow: ecological speciation in a pathogenic parasite of freshwater fish

This study investigates genetic differentiation in a tapeworm parasite despite ongoing gene flow, identifying genomic and transcriptomic signatures of host-specific adaptation and ecological speciation.

Novel reassortments of variation underlie repeated adaptation to whole genome duplication in two outcrossing Arabidopsis species

The paper identifies repeated selection signals in genes related to adaptation to whole genome duplication in two Arabidopsis species, showing that tetraploid-specific haplotype blocks arise from diverse allelic sources.

Parallel adaptation in autopolyploid Arabidopsis arenosa is dominated by repeated recruitment of shared alleles

The paper investigates adaptation in autopolyploid Arabidopsis arenosa, finding that parallel adaptation is driven by shared alleles and rare de novo mutations in ion homeostasis genes.

Genomic basis of parallel adaptation varies with divergence in Arabidopsis and its relatives

The paper investigates genomic parallelism in Arabidopsis species adapting to alpine environments, finding that parallel adaptation decreases with increasing genetic divergence between lineages.
