Research published on March 11, 2026, highlights that female aggression among Bahamas mosquitofish significantly contributes to behavioral isolation between populations.
This aggression is not merely a byproduct of mating choices; it includes active resistance that can lead to increased speciation rates.
The findings suggest a need to reevaluate existing models of speciation in aquatic species, considering both behavioral and ecological factors.
