Gene expression signatures of salinity transitions in Limia perugiae (Poeciliidae), with comparisons to other teleosts

This study uses RNA-seq to compare gene expression between freshwater and hypersaline populations of Limia perugiae, finding limited convergence in differentially expressed genes across teleosts.

Recurrent evolution of small body size and loss of the sword ornament in Northern Swordtail fish

The paper uses whole-genome sequencing to resolve phylogenetic relationships in Xiphophorus fish, revealing recurrent loss of sexually selected traits like body size and sword ornaments.

Genetics and resource availability shape divergence in life history and behavior between locally-adapted populations of Atlantic mollies (Poecilia mexicana, Poeciliidae)

This study investigates how genetics and maternal effects influence life history and behavior in Atlantic mollies, finding that genetic differentiation drives most phenotypic differences, while maternal effects have a smaller impact.

Ecology drives the degree of convergence in the gene expression of extremophile fishes

This study shows that convergence in gene expression among extremophile fishes is strongly influenced by ecological similarity rather than phylogenetic relatedness.

Integrative analyses of convergent adaptation in sympatric extremophile fishes

The paper examines convergent adaptation in three sympatric fish species exposed to H2S, finding convergence in traits and gene expression but not in genomic divergence patterns.

Ecology and the diversification of reproductive strategies in viviparous fishes

The paper investigates ecological drivers of evolutionary transitions in livebearing fishes between lecithotrophy and matrotrophy, finding correlations with resource availability and competition.

Convergent evolution of conserved mitochondrial pathways underlies repeated adaptation to extreme environments

This study identifies convergent genetic and physiological adaptations in multiple fish lineages that enable tolerance to hydrogen sulfide, showing that conserved mitochondrial pathways are repeatedly modified for H2S resistance.
