Behavioral isolation due to cascade reinforcement in Lucania killifish

Reinforcement occurs when behavioral isolation is strengthened between species due to selection against hybridization in sympatry. Mate preferences and their target traits may change in sympatry as a consequence of reinforcement. This can potentially generate further behavioral isolation within species if sympatric populations evolve extreme preferences or traits that cause them to reject individuals from foreign populations as mates or be rejected as mates. This process is known as cascade reinforcement. We measured behavioral isolation between sympatric and allopatric populations of Lucania killifish to determine whether isolation evolves due to reinforcement between species and whether reinforcement affects preferences within species, consistent with the cascade reinforcement hypothesis. We measured mate preferences in both sexes between species (Lucania parva vs. Lucania goodei) and within species (among populations of L. parva). Between species, both male and female preferences for...,
Between species mating trial data
This file contains the data for time spent with conspecific (Con) or heterospecific (Het) mates when focal fish had the choice between both. Time measured in seconds (out of 600 second trials). Allopatric and Sympatric focal fish compared. Data for Figure 2 of the paper.

Between population female mating trial data
This file contains association time (in seconds) for female L. parva given the choice between males of their own population or males of a foreign population. Foreign populations could either be from the same salinity environment (ecology) or different salinity. Females came from populations that were either sympatric with L. goodei or allopatric. Data for Figure 3 and Figure 5.

Between population male mating trial data
This file contains association time (in seconds) for L. parva males choosing between females from their own population or a foreign population. Focal males were from populations sympatric ...,
