Differences in Agonistic Behavior and Energy Metabolism between Male and Female Swimming Crab Based on the Analysis of Boldness.

Individual differences in metabolism and agonistic behavior have been a key research area in evolution and ecology recently. In this study, we investigated the boldness of swimming crabs and explored the agonistic behavior between female and male crabs, specifically examining competitions between bold females vs. bold males (BF-BM), bold females vs.

What Forms, Maintains, and Changes the Boldness of Swimming Crabs ()?

Boldness of personality is an important theme in animal behavior and has significant ecological and evolutionary consequences. Studies on boldness in crustaceans typically focus on their behavior, while relatively few studies have focused on the formation and maintenance of and change in boldness, such as energy metabolism and neurotransmission. In this study, we measured the boldness of swimming crabs () and analyzed the relationship between boldness and oxygen consumption rate, energy concentration, and the relative expression of energy-metabolism-related and 5-HT genes in mRNA.

Agonistic behaviour and energy metabolism of bold and shy swimming crabs .

The metabolism and behaviour of crustaceans are highly flexible, and the inter-individual variation in these traits is evolutionarily and ecologically significant. We analysed the relationships among personality traits (boldness, activity and hesitancy), agonistic behaviour and energy status (glycogen, glucose and lactate) in the swimming crab The main results were as follows. (1) Boldness was significantly correlated with activity and hesitancy.
