Poster summary

Green swordtails exhibited a behavioral syndrome on the axes of boldness, aggression, and exploration. This behavioral syndrome was detected in a native population, invasive population, and hybrid breeding population – therefore, it cannot be called an invasive syndrome. Differences between native and hybrid breeding populations suggests that the breeding pool or method used to harvest fish is driving differences in behavior observed.
