Behavioural syndromes are suites of behaviours that corelate between-individuals but the same may also show within-individual correlations owing to state dependency or trade-offs. Therefore, overall phenotypic behavioural must be separated into their between- and components. We investigate how startle response duration (an index boldness) time taken reject an inert item investigation thoroughness) covary in beadlet sea anemones, Actinia equina . Anemones took longer a more complex compared simpler one, validating this measure thoroughness. then quantified using Bayesian analysis alternative frequentist analysis, which returned results. Startle responses decreased with anemone size while thoroughness across repeated observations, indicative simple learning. For each behaviour, repeatability was significant relatively low there no syndrome. Rather, two showed negative correlation most individuals. Thus, boldness unlikely under correlative selection, they instead expressed independently, line general pattern cross-contextual comparatively rare. It now appears extend broadly animal diversity.

Animal personality and sentience as distinct concepts

Animal Sentience, Journal Year: 2024, Volume and Issue: 9(34)

Published: Jan. 1, 2024

Owens et al (2024) discuss how knowledge of both animal personality and sentience in target populations can be leveraged to enhance wildlife conservation programmes. In this commentary I expand on the distinction between these two concepts. Behavioural differences should considered broadly across programmes, not just those involving species deemed sentient.
