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

This study compares reproductive strategies between two swordtail fish species, finding that X. malinche produces larger, more resilient offspring through extended post-fertilization nutrient provisioning.

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.

The paper shows that local ancestry in hybrid swordtail fish populations is repeatable due to strong early selection, and this repeatability increases with deeper evolutionary divergence.
