Among-individual behavioural variation in the ornamental red cherry shrimp, Neocaridina heteropoda

Personality variation, defined as among-individual differences in behaviour that are repeatable across time and context, has been reported across animal taxa. From an evolutionary perspective, characterising the amount and structure of this variation is useful since differences among-individuals are the raw material for adaptive behavioural evolution. However, it is becoming apparent that behavioural variation among-individuals also has implications for more applied areas of evolution and ecology – from invasion biology, to ecotoxicology, and selective breeding in captive systems. Here, we investigate the structure of personality variation in the red cherry shrimp, Neocaridina heteropoda, a popular ornamental species that is readily kept and bred under lab conditions and is emerging as a decapod crustacean model across these fields, but for which basic biological, ecological, and behavioural data is limited. Using two assays and a repeated measures approach, we quantify behaviours putat..., Refer to Methods in the associated manuscript., , # Among-individual behavioural variation in the ornamental red cherry shrimp, Neocaridina heteropoda
