This study examines how hybridization impacts genomes at different stages of speciation in monkeyflowers, finding that selection against recent introgression is stronger than against ancient introgression.

The paper investigates the fitness effects of inherited somatic mutations in Mimulus aurantiacus through autogamy and geitonogamy, finding increased fecundity and impacts on drought tolerance, survival, and biomass.

The paper integrates top-down and bottom-up approaches to study speciation in a monkeyflower hybrid zone, finding that reproductive isolation involves widespread genomic barriers and polygenic traits.

The paper uses geographic cline analysis to study genome-wide divergence in Mimulus aurantiacus ecotypes, finding that outlier loci are scattered and linked to pollinator-mediated divergence.
