Parasite infection disrupts escape behaviour in fish shoals

Nicolle Demandt, Marit Praetz, Ralf Kurvers, Jens Krause, Joachim Kurtz & Jörn Scharsack
Many prey species have evolved collective responses to avoid predation. They rapidly transfer information about potential predators to trigger and coordinate escape waves. Predation avoidance behaviour is often manipulated by trophically transmitted parasites, to facilitate their transmission to the next host. We hypothesised that the presence of infected, behaviourally altered individuals might disturb the spread of escape waves. We used the tapeworm Schistocephalus solidus, which increases risk-taking behaviour and decrease social responsiveness of its host,...
