Whole genome sequencing of 56 Mimulus individuals illustrates population structure and local selection

The paper uses whole genome sequencing of 56 Mimulus individuals to study population structure and local selection, finding high polymorphism, positive Tajima's D, and distinctive haplotype structure.

Adaptation to heavy-metal contaminated environments proceeds via selection on pre-existing genetic variation

The paper shows adaptation to copper-contaminated environments in Mimulus guttatus occurs through selection on pre-existing genetic variation rather than new mutations.

Disruption of endosperm development is a major cause of hybrid seed inviability between Mimulus guttatus and M. nudatus

A segregating inversion generates fitness variation in a yellow monkeyflower (Mimulus guttatus) population

The paper identifies a segregating inversion in Mimulus guttatus that has mixed fitness effects, contributing to genetic variation and inbreeding depression.
