Data from: Drivers and cascading ecological consequences of Gambusia affinis trait variation

Zachary Wood, Laura Lopez, Celia Symons, Rebecca Robinson, Eric Palkovacs & Michael Kinnison
Phenotypic trait differences among populations can shape ecological outcomes for communities and ecosystems. However, few studies have mechanistically linked heritable and plastic components of trait variation to generalizable processes of ecology, such as trophic cascades. Here we assess morphological and behavioral trait variation in nine populations of common-garden reared western mosquitofish (Gambusia affinis) from three distinct ancestral predator environments (three populations per environment), each reared in the presence and absence of predator cues. We then...
