Episodic correlations in behavioural lateralization differ between a poison frog and its mimic

摘要: Sensory and behavioural lateralization is thought to increase neural efficiency facilitate coordinated behaviour across much of the animal kingdom. Complementary laterality, when tasks are lateralized opposite sides, can multitasking, but predictable may predation risk. Laterality is, however, variable in its scale, existing at both population individual level. Population level coordination social behaviours whereas biases promote efficiency. We studied sympatric wild populations two terrestrial frog species: Ecuador poison frog, Ameerega bilinguis, Batesian mimic sanguine Allobates zaparo. used a multivariate approach study four different behaviours: (interactions with conspecifics heterospecifics) nonsocial prey simulated predator). investigated three questions: (1) what scale lateralized, (2) complementary manner, (3) scales? found no evidence nor limited for Al. zaparo not Am. bilinguis. only weak differences between zaparo, although counter our prediction, was weakly However, we did detect robust, species- task-specific within-individual correlations. Specifically, bilinguis showed shared side use individuals certain consecutive trials, while alternating trials. Our results suggest that be more than previously manifest an episodic fashion under conditions.
