Predicting rapid adaptation in time from adaptation in space: a 30-year field experiment in marine snails

The paper predicts rapid temporal adaptation in marine snails using spatial genetic and phenotypic variation from a 30-year transplant experiment, finding observed changes align with predictions.

Phenotypic divergence and genomic architecture between parallel ecotypes at two different points on the speciation continuum in a marine snail

The paper compares parallel ecotypes of Littorina saxatilis in Spain and Sweden to assess divergence in gene flow, finding stronger reproductive isolation in Spain despite similar phenotypic divergence.

Parallel evolution of local adaptation in Littorina saxatilis inferred with whole-genome pool-seq data

The paper uses whole-genome pool-seq data and approximate Bayesian computation to show parallel ecotype formation in Littorina saxatilis across Spain and Sweden despite gene flow.

Selection on many loci drove the origin and spread of a key innovation

The paper investigates the genetic basis of a key innovation in Littorina snails, finding polygenic selection and gradual evolution of live-bearing traits.

Identification of candidate virulence loci in Striga hermonthica, a devastating parasite of African cereal crops

The paper identifies candidate virulence loci in Striga hermonthica by analyzing allele frequency differences between resistant and susceptible hosts.

Supergene degeneration opposes polymorphism: The curious case of balanced lethals

This study uses simulations to explore how mutation accumulation and asymmetric degradation affect the stability of supergene polymorphisms and the emergence of balanced lethal systems.

A large chromosomal inversion shapes gene expression in seaweed flies (Coelopa frigida)

This study examines how the Cf-Inv(1) chromosomal inversion in seaweed flies affects gene expression across sexes and life stages, identifying candidate variants that may influence adaptive traits.

Deleterious Mutation Accumulation and the Long-Term Fate of Chromosomal Inversions

This study uses simulations to show that recessive deleterious mutations accumulate in chromosomal inversions, leading to fitness decline and non-adaptive divergence, but can be halted by haplotype branching.

Assortative mating, sexual selection and their consequences for gene flow in Littorina

This study examines size-assortative mating in Littorina saxatilis and shows it contributes to reproductive isolation but sexual selection has a stronger impact on reducing gene flow between ecotypes.

Evidence for natural selection and barrier leakage in candidate loci underlying speciation in wood ants

The paper identifies candidate barrier loci in wood ants and finds evidence of natural selection and gene flow over time.

Phylogenomics of the adaptive radiation of Triturus newts supports gradual ecological niche expansion towards an incrementally aquatic lifestyle

The paper resolves the phylogeny of Triturus newts using transcriptome data and shows that NTV count, body form, and aquatic ecology have evolved together.

Conflict between heterozygote advantage and hybrid incompatibility in haplodiploids (and sex chromosomes)

The paper models hybrid incompatibility and heterozygote advantage in haplodiploid species, showing how these factors lead to sexual conflict and different population outcomes.
