Contrasting coping styles meet the wall: A dopamine driven dichotomy in behavior and cognition
2017
Individual variation in the ability to modify previously learned behaviour is an important dimension of trait correlations referred to as coping styles, behavioral syndromes or personality. These trait clusters have been shaped by natural selection, and underlying control mechanisms are often conserved throughout vertebrate evolution. In teleost fishes, behavioral flexibility and coping style have been studied in the high (HR) and low-responsive (LR) rainbow trout lines. Generally, proactive LR trout show a behaviour guided by previously learned routines, while HR trout show a more flexible behaviour relying on environmental cues. In mammals, routine dependent vs flexible behavior has been …
Human cooperation in groups: variation begets variation
2015
Open Access Published: 04 November 2015 Human cooperation in groups: variation begets variation Pieter van den Berg, Lucas Molleman, Jaakko Junikka, Mikael Puurtinen & Franz J. Weissing Scientific Reports volume 5, Article number: 16144 (2015) Cite this article 383 Accesses 4 Citations 6 Altmetric Metricsdetails Abstract Many experiments on human cooperation have revealed that individuals differ systematically in their tendency to cooperate with others. It has also been shown that individuals condition their behaviour on the overall cooperation level of their peers. Yet, little is known about how individuals respond to heterogeneity in cooperativeness in their neighbourhood. Here, we presen…
Data from: Pace-of-life in a social insect: behavioral syndromes in ants shift along a climatic gradient
2017
Behavioral syndromes are correlations between behavioral traits, but their selective advantage under different environmental conditions is not well understood. Here, we used the pace-of-life hypothesis to predict how behavioral syndromes could vary along climatic gradients. This hypothesis states that populations experiencing different ecological conditions should differ in suites of physiological characteristics associated with behavioral and life-history traits. We examined the persistence of behavioral syndromes at multiple levels in the ant Temnothorax longispinosus along a climatic gradient in north-eastern USA. “Across populations”, we predicted that proactive phenotypes, which show h…
