Selection-driven trait loss in independently evolved cavefish populations

This study shows that selection, not mutation, drives repeated trait evolution in cavefish, with genes having longer coding regions being more likely to undergo repeated adaptation.

Hybridization underlies localized trait evolution in cavefish

This study shows hybridization contributes to localized trait evolution in cavefish by analyzing genomic and phenotypic variation in Chica cave pools.

Agonistic character displacement of genetically based male color patterns across darters

This study shows that male color patterns in darters are genetically based and exhibit greater divergence in sympatric populations, supporting agonistic character displacement driven by male-male competition.

Hybridization and postzygotic isolation promote reinforcement of male mating preferences in a diverse group of fishes with traditional sex roles

The paper shows hybridization and postzygotic isolation drive reinforcement of male mating preferences in darters, leading to behavioral isolation.

Egg viability decreases rapidly with time since ovulation in the rainbow darter: implications for the costs of choosiness

The paper shows that egg viability in rainbow darters drops quickly after ovulation, suggesting that females may face costs from delaying mating.

Male-driven reinforcement and cascade reinforcement in darters

This study shows male-driven reinforcement between darter species leads to behavioral isolation within a species through cascade reinforcement.
