Among-individual behavioural variation
Our shrimp population shows significant among-individual differences in all behavioural traits measured in OFT and FST assays bar -(Food Latency) (Table 2). Thus, behaviours are repeatable with a median of R=0.353 (range 0.168 – 0.626) conditional on fixed effects (Figure 2, blue points). Fixed effect estimates from these models are not relevant to biological hypotheses but are presented in the Supplementary Material (Table S2).
