The pitfall with PIT tags: marking freshwater bivalves for translocation induces short-term behavioural costs
Tagging animals is frequently employed in ecological studies to monitor individual behaviour, for example postrelease survival and dispersal of captive-bred animals used in conservation programmes. While the majority of studies focus on the efficacy of tags in facilitating the relocation and identification of individuals, few assess the direct effects of tagging in biasing animal behaviour. […]
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 […]
