Effects of nautical traffic and noise on foraging patterns of Mediterranean damselfish (Chromis chromis).

Chromis chromis is a key species in the Mediterranean marine coastal ecosystems where, in summer, recreational boating and its associated noise overlap. Anthropogenic noise could induce behavioural modifications in marine organisms, thereby affecting population dynamics. In the case of an important...
