Freshwater Pearl Mussels Show Plasticity of Responses to Different Predation Risks But Also Show Consistent Individual Differences in Responsiveness

Animals often show behavioural plasticity with respect to predation risk but also show behavioural syndromes in terms of consistency of responses to different stimuli. We examine these features in the freshwater pearl mussel. These bivalves often aggregate presumably to reduce predation risk to each individual. Predation risk, however, will be higher in the presence of […]
