Increased rates of hybridization in swordtails are associated with water pollution

The paper investigates how water pollution affects hybridization between two swordtail fish species by analyzing genomic and environmental data.

Two melanic pigment patterns are associated with a sex chromosome-linked oncogene in the mountain swordtail Xiphophorus nezahualcoyotl

This study identifies two melanic pigmentation patterns in Xiphophorus nezahualcoyotl linked to the sex chromosome-linked oncogene xmrk through long-read sequencing and GWAS.

Insertion of an invading retrovirus regulates a novel color trait in swordtail fish

This study identifies a retrovirus insertion near the alkal2a gene as the genetic basis for a novel iridescent color trait in swordtail fish, showing its role in chromatin changes and predator interaction signals.

Admixture mapping reveals evidence for multiple mitonuclear incompatibilities in swordtail fish hybrids

The paper uses admixture mapping in swordtail fish hybrids to identify mitonuclear incompatibilities, finding nine genomic regions involved in interactions between nuclear and mitochondrial genomes.

Pervasive gene flow despite strong and varied reproductive barriers in swordtails

This study shows that despite strong reproductive barriers, gene flow is pervasive between closely related swordtail fish species through hybridization and genetic incompatibilities.

Complex structural variation and behavioral interactions underpin a balanced sexual mimicry polymorphism

The paper identifies a genetic basis for a sexual mimicry polymorphism in swordtail fish and links it to behavioral interactions that may maintain the polymorphism.
