A laboratory study was conducted to observe patterns of social behaviour of males of the sexually dimorphic rainbow skink, Carlia rostralis. Animals were observed alone or in matched pairs, both as residents and non-residents of the testing cage. Behavioural patterns observed included active, aggressive, submissive, assertive, exploratory and escape categories of acts. These patterns of behaviour varied in social contexts. Active behaviour increased significantly when males were paired. Of the paired encounters, 60% had neutral outcomes in which no dominant/subordinate individual could be determined. When dominance/subordinance interactions occurred they were found to be expressed in a linear hierarchy. Dominance was positively correlated with male snout-vent length. Dominance of males was absolute and did not depend on residence status. These observations of social behaviour in the laboratory, together with preliminary observations of behaviour of this species in the field, suggest that Carlia rostralis exhibits different patterns of social behaviour from that observed in other scincid lizards.

The Social

Bees provide an excellent model with which to study the neuronal and molecular modifications associated with the evolution of sociality because relatively closely related species differ profoundly in social behaviour, from solitary to highly social. The recent development of powerful genomic tools and resources has set the stage for studying the social behaviour of bees in molecular terms. We review ‘ground plan’ and ‘genetic toolkit’ models which hypothesize that discrete pathways or sets of genes that regulate fundamental behavioural and physiological processes in solitary species have been co-opted to regulate complex social behaviours in social species. We further develop these models and propose that these conserved pathways and genes may be incorporated into ‘social pathways’, which consist of relatively independent modules involved in social signal detection, integration and processing within the nervous and endocrine systems, and subsequent behavioural outputs. Modifications within modules or in their connections result in the evolution of novel behavioural patterns. We describe how the evolution of pheromonal regulation of social pathways may lead to the expression of behaviour under new social contexts, and review plasticity in circadian rhythms as an example for a social pathway with a modular structure.

Despite improved treatments, patients with atrial fibrillation are in need of personalized management to improve outcomes, and personalized strategies for atrial fibrillation prevention are needed to avoid the emerging atrial fibrillation epidemic. The pathophysiological heterogeneity driving atrial fibrillation and most likely its complications has led to a demand for a new disease taxonomy that better reflects disease mechanisms in atrial fibrillation. Genomic and biomedical differences could guide such a taxonomy as well as different social contexts and behavioural patterns. Interdisciplinary cooperation between scientists, clinicians and other healthcare providers, regulators, industry government agencies, and charities is required, to unleash the potential of personalized management of atrial fibrillation.

The Social

In a breeding population of crested terns near Fremantle, W.A., social behaviour involved complex patterns of social displays and paired behaviour. The social phase was probably truncated over much of the extended breeding season by the presence of incubating conspecifics, and may serve to synchronise laying in their absence. The responses of pre-laying crested terns to incubating conspecifics were studied by means of artificial 'colonies' of polyurethane models. These proved to be most attractive to prebreeding pairs searching for nest sites, and the earliest eggs were invariably laid among the decoys. Pre-breeding terns in the social phase were not attracted to the decoys. It is suggested that loose groups of incubating conspecifics acted as a key stimulus, releasing settlement and laying in birds in an advanced state of reproductive readiness. This key stimulus could change the learned location of colonies but during late summer and early autumn other factors, probably related to food availability, controlled the onset of laying. Small, spatially distinct, nesting groups were less synchronous in their laying than larger colonies. Such small groups are thought to result from discontinuities in reproductive phase between groups of terns, which are not apparent when the number of pre-laying birds is large.

The Social

The seventh chapter argues for the importance of the social context in continuing to influence whether social cognition is engaged or not, and describes a version of the delayed sudden death virus outbreak thought experiment without the death and virus components, set in modern society. This chapter then reviews classical social psychological studies that illustrate the power of the social context in shaping social cognition and resulting behaviour. It describes different types of social contexts, and explores the role of consistency motives in guiding human behaviour. Finally, it makes an appeal for a spectrum metaphor for social behavior, rather than alternative metaphors that categorise the phenomenon too narrowly.

Abstract Background Glucocorticoids (e.g. cortisol) are associated with variation in social behavior, and previous studies have linked baseline as well as challenge-induced glucocorticoid concentrations to dominance status. It is known that cortisol response to an acute challenge is repeatable and correlates to social behavior in males of many mammal species. However, it is unclear whether these patterns are also consistent for females. The aim of this study was to investigate whether baseline and response cortisol concentrations are repeatable in female guinea pigs (Cavia aperea f. porcellus) and whether dominance rank is stable and correlated to baseline cortisol concentration and/or cortisol responsiveness. Results Our results show that cortisol responsiveness (after 1 h: R = 0.635, 95% CI = 0.229, 0.927; after 2 h: R = 0.764, 95% CI = 0.433, 0.951) and dominance rank (R = 0.709, 95% CI = 0.316, 0.935) of females were significantly repeatable after six weeks but not correlated. Baseline cortisol was not repeatable (R = 0, 95% CI = 0, 0.690) and also did not correlate to dominance rank. Furthermore, the difference in repeatability estimates of baseline and response values was due to high within-individual variance of baseline cortisol concentration; the amount of between-individual variance was similar for baseline cortisol and the two measures of cortisol responsiveness. Conclusions Females occupying different dominance ranks did not have long-term differences in cortisol concentrations, and cortisol responsiveness does not seem to be significantly involved in the maintenance of dominance rank. Overall, this study reveals the remarkable stability of cortisol responsiveness and dominance rank in a female rodent, and it remains an open question whether the magnitude of cortisol responsiveness is adaptive in social contexts for females.

The present study attempts to study the relationship between internet addiction and internet social behaviour with personality. The sample consisted of 365 Grade 10 students from two secondary schools in Mainland China. Four instruments were used: Young’s Internet Addiction Test, Chen Internet Addiction Scale, Ma, Li & Pow’s Adolescent Internet Use Questionnaire, and Eysenck Personality Questionnaire. Boys scored significantly higher than girls in the two Internet addiction questionnaires. Results also supported the following hypotheses: (1) Internet addiction is positively associated with psychoticism, neuroticism, and frequency of Internet use; and it is also negatively associated with social desirability and self-concept. (2) Holistic Internet social behavior is positively associated with extroversion, social desirability, self-concept, and frequency of Internet use; and it is also negatively associated with psychoticism and neuroticism. A high (low) rating of Holistic Internet Social Behavior refers to a high (low) rating of Prosocial Internet Behaviour and a low (high) rating of Antisocial Internet Behaviour.

Key aspects of the social behaviour of groups of drift-feeding fish can be inferred by the way space is shared between group members, because they inhabit a very dynamic and complex environment where spatial positions have a direct impact on fitness-related traits. Therefore, the spatial analysis of such a system can reveal important insights into behavioural ecology of fish, but so far, technical constraints limited this approach to only large salmonids. We used a digital imaging technique to monitor movements and behaviour of free-ranging groups of juvenile galaxiids (Galaxias anomalus) facing two contrasting physical and social contexts. We described the spatial structure of these groups and studied individual space use in relation to their social behaviour. We found that prevalence of territorial behaviour differs greatly between sites, which suggests that groups were displaying different social organisation. This study showed that detailed spatial analysis of space use and behaviour of drift-feeding fish could provide new insights into the social organisation of group-living animals.
