Transcriptomic sexual conflict at two evolutionary timescales revealed by experimental evolution in Caenorhabditis elegans

This study uses experimental evolution in C. elegans to show sex-specific gene expression changes driven by sexual selection, revealing transcriptomic sexual conflict over short evolutionary timescales.

Genetic diversity landscapes in outcrossing and selfing Caenorhabditis nematodes

This study compares genetic diversity and recombination patterns between outcrossing and selfing Caenorhabditis nematodes, finding similar genomic patterns but differing in scale and effective population size history.

The genetic basis of traits associated with the evolution of serpentine endemism in monkeyflowers

This study identifies genetic loci associated with adaptive traits and prezygotic reproductive isolation in serpentine-endemic monkeyflowers, showing overlap between loci contributing to adaptation and speciation.

Alignment of genetic differentiation across trophic levels in a fig community

The paper examines genetic diversity patterns in the nematode C. inopinata across three Okinawan islands, finding it more diverse than C. elegans and showing genetic patterns aligned with its fig wasp vector.

Post-Insemination Selection Dominates Pre-Insemination Selection in Driving Rapid Evolution of Male Competitive Ability

This study shows post-insemination selection is more effective than pre-insemination selection in driving rapid evolution of male reproductive success in C. elegans.

The genetic architecture and evolution of life history divergence among perennials in the Mimulus guttatus species complex

The paper examines how elevation-driven divergence affects life history traits in Mimulus guttatus species, finding simple genetic architectures and developmental changes in rhizome production.

Slow recovery from inbreeding depression generated by the complex genetic architecture of segregating deleterious mutations

This study investigates recovery from inbreeding depression in C. remanei, finding limited fitness recovery despite strong selection, due to the fixation of many segregating deleterious mutations.

Patterns of hybrid seed inviability in perennials of the Mimulus guttatus sp. complex reveal a potential role of parental conflict in reproductive isolation

This study examines hybrid seed inviability in Mimulus species, finding patterns consistent with parental conflict driving reproductive isolation.

Parallel patterns of development between independent cases of hybrid seed inviability in Mimulus

The paper examines hybrid seed inviability in Mimulus, finding parent-of-origin effects and developmental parallelism in multiple cases.

Differential Adaptation to a Harsh Granite Outcrop Habitat between Sympatric Mimulus Species

This study compares adaptation to a harsh granite outcrop habitat between two sympatric Mimulus species, finding that drought and herbivory drive survival differences and that different traits confer fitness in each environment.

Major QTL controls adaptation to serpentine soils in Mimulus guttatus

This paper identifies a major QTL controlling serpentine soil adaptation in Mimulus guttatus through reciprocal transplant and bulk segregant analysis.

Population-genomic inference of the strength and timing of selection against gene flow

The paper infers the strength and timing of selection against gene flow using DNA polymorphism data and recombination rate variation in Mimulus guttatus.
