The paper presents a genomic resource with 1018 A. lyrata and 736 A. arenosa genomes, enabling studies of adaptation and genetic diversity through a searchable database and GWAS analysis of latitudinal clines.

The paper compares resource partitioning strategies in two tropical alpine ecosystems to explain differences in species richness.

This study examines how whole-genome duplication affects genetic diversity and mutation load in Arabidopsis arenosa, showing increased diversity but modest load increases.

This paper challenges assumptions about polyploidy success by developing a theoretical model showing diploid adaptation, not tetraploid fixation, drives adaptation to new environments.

The paper identifies multiple origins of autotetraploidy in Arabidopsis lyrata across Eurasia and shows how adaptive introgression stabilizes these polyploid forms.
