Despite increasing interest in the evolution of inhibitory control, few studies have examined validity widespread testing paradigms, long-term repeatability and heritability this cognitive ability wild. We investigated these aspects control performance wild toutouwai (North Island robin; Petroica longipes), using detour reversal learning tasks. assessed convergent by whether individual correlated across then further evaluated task examining was confounded non-cognitive factors. tested a subset subjects twice each to estimate 1-year period. Finally, we used population pedigree performance. Individual unrelated tasks, indicating that measured different abilities. Task not influenced body condition, boldness or prior experience, showed moderate between-year repeatability. Yet despite consistency, found no evidence heritable. Our findings suggest tasks measure consistent differences distinct forms toutouwai, but variation may be environmentally determined rather than genetic.

Elucidating the selective forces shaping diversity of vertebrate brains continues to be a major area inquiry, particularly as it relates cognition. Historically brain evolution was interpreted through lens relative size; however, recent evidence has challenged this approach. Investigating neuroanatomy at finer scale, such neuron number, can provide new insights into in context information processing capacity. Ecological factors, complexity species' habitat, place demands on cognition that could shape neuroanatomy. In study, we investigate relationship between number and habitat three regions across six closely related anole species from Puerto Rico. After controlling for mass, found neurons increased with telencephalon ‘rest brain,’ but not cerebellum. Our results demonstrate shaped Rican radiation further role evolution.

Abstract It is well established that, across taxa, individuals within populations exhibit consistent differences in their behaviour time and/or contexts. Further, the functional coupling of traits may result formation a behavioural syndrome. Despite extensive evidence on existence among-individual and syndromes animal realm, these findings are predominately based upon short-term assessments, leading to questions regarding stability over longer periods. Understanding if estimates temporally stable would allow predictions individual be made using repeated measures. Here, we used 57 adult male delicate skinks ( Lampropholis delicata ) evaluate variation observed both among (animal personality plasticity) (behavioural predictability), as syndromes, short (four weeks) long (five months) timeframes. To do so, repeatedly assayed activity, exploration, boldness five times per each individual. Overall, our study revealed complex patterns trait (co)variation time. Activity was always repeatable intervals, whereas exploration were not consistent. Yet syndrome between activity detected at shorter temporal scales, suggesting that structure does vary function Our indicate least for some (e.g. activity) studies, measures adequate serving proxy long-term behaviour, reveal population level.

Abstract Many predators avoid unprofitable prey by learning to use visual features of the as reliable indicators quality. However, individual variation in avoidance is rarely examined detail.

Cognitive flexibility controls how animals respond to changing environmental conditions. Individuals within species vary considerably in cognitive but the micro-evolutionary potential animal populations remains enigmatic. One prerequisite for be able evolve is consistent and heritable among-individual variation. Here we determine repeatability heritability of among great tits (

Specifically, measure inhibitory control which affect how animals respond resources challenges.
