Warming affects the feeding success of invader and native fish in Iberian streams

We experimentally tested the effects of anticipated warmer temperatures on feeding success invasive pumpkinseed and chameleon cichlid functionally similar Southern Iberian chub. Singly, prey captures by chub were constant but those affected warming. Moreover, at temperatures, captured much less in presence faster than with conspecifics. Warming are likely species dependent, asymmetries between may be enhanced to benefit warm-water invaders.
