Cognitive abilities are crucial for survival and adaptation, enabling animals to navigate their environment, recognize predators remember the location of food resources. However, underlying factors related learning memory can be energetically demanding thus may vary depending on an individual's metabolism or aerobic capacity, potentially affecting individuals' cognitive performance. In this study, we explored link between performance whole-body metabolic traits, including scope (AS), maximum rate (MMR) standard (SMR). European minnows, Phoxinus phoxinus, were trained over 20 days locate a reward in maze. Individuals either simple (two-door) complex (four-door) Fish simpler maze had consistently higher success lower latency reach reward, suggesting two-door was less cognitively challenging. We found correlation traits (i.e. reward) at end training. relationship varied complexity. maze, individuals with MMR SMR reward. more fish rates (MMR SMR) AS followed similar patterns but mostly affected environments, having beneficial performance, whereas as it could associated slower thorough exploration process.

Social insects exhibit a high degree of intraspecific behavioral variation. Moreover, they often harbor specialized microbial communities in their gut. Recent studies suggest that these two characteristics social are interlinked: insect phenotypes affect gut microbiota composition, partly through exposure to different environments and diet, return, the has been shown influence behavior. Here, we discuss bidirectional relationship existing between variation composition insects.

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.
