Data on zoo enclosure usage provide meaningful evaluation of husbandry and welfare but for social species, group-level data may not capture individual occupancy preferences. Determining zone occupancy using group data may give an inaccurate assessment of enclosure suitability for each individual. We compared three formulae (traditional and modified Spread of Participation Index and Electivity Index) to determine how estimations of space usage compare between individuals and their group overall. Two flamingo flocks at two zoos were sampled with enclosures separated into discrete zones. Counts of where each bird in the flock was located at each minute of sampling were compared against the number of minutes that randomly selected individual flamingos spent in each zone. Overall, there was little difference in preferred zone occupancy when flock data were compared to individual data. Group data suggested that flamingos were more consistent in their enclosure usage, with individual data showing wider overall usage of enclosures. Individual Electivity Index (EI) values suggested zone underuse whereas group EI suggested zone overuse. As a proxy for welfare measurement, we recommend both group-level and individual monitoring of space use to provide a complete picture of how individuals within a social group occupy their space and choose where to be.

Antipredator defensive traits are thought to trade-off evolutionarily with traits that facilitate predator avoidance. However, complexity and scale have precluded tests of this prediction in many groups, including fishes. Using a macroevolutionary approach, we test this prediction in butterflyfishes, an iconic group of coral reef inhabitants with diverse social behaviours, foraging strategies and antipredator adaptations. We find that several antipredator traits have evolved adaptively, dependent primarily on foraging strategy. We identify a previously unrecognised axis of diversity in butterflyfishes where species with robust morphological defences have riskier foraging strategies and lack sociality, while species with reduced morphological defences feed in familiar territories, have adaptations for quick escapes and benefit from the vigilance provided by sociality. Furthermore, we find evidence for the constrained evolution of fin spines among species that graze solely on corals, highlighting the importance of corals, as both prey and structural refuge, in shaping fish morphology.

Humans in strong social relationships are more likely to live longer because social relationships may buffer stressors and thus have protective effects. However, a shortcoming of human studies is that they often rely on self-reporting of these relationships. By contrast, observational studies of non-human animals permit detailed analyses of the specific nature of social relationships. Thus, discoveries that some social animals live longer and healthier lives if they are involved in social grooming, forage together or have more affiliative associates emphasizes the potential importance of social relationships on health and longevity. Previous studies have focused on the impact of social metrics on longevity in obligately social species. However, if sociality indeed has a key role in longevity, we might expect that affiliative relationships should also influence longevity in less social species. We focused on socially flexible yellow-bellied marmots (Marmota flaviventer) and asked whether female longevity covaries with the specific nature of social relationships. We quantified social relationships with social network statistics that were based on affiliative interactions, and then estimated the correlation between longevity and sociality using bivariate models. We found a significant negative phenotypic correlation between affiliative social relationship strength and longevity; marmots with greater degree, closeness and those with a greater negative average shortest path length died at younger ages. We conclude that sociality plays an important role in longevity, but how it does so may depend on whether a species is obligately or facultatively social.

Rats adapt their food choices to conform to their conspecifics' dietary preferences. The nucleus accumbens shell is a relevant brain region to process reward‐related and motivated behaviours and social information. Here, we hypothesize that the integrity of the nucleus accumbens shell is necessary to show socially transmitted food preferences. We made excitotoxic and sham lesions of nucleus accumbens shell in male Long–Evans rats who performed a social transmission of food preference task. In this task, observer rats revealed their original preference for one out of two food options. Afterward, they were exposed to a demonstrator rat who was fed with the observer's originally non‐preferred food, and the observer's food choices were sampled again. Sham lesioned observer rats changed their food preferences following interaction with the demonstrator, specifically by increasing the intake of their originally non‐preferred food type. This interaction‐related change in preference was not found after nucleus accumbens shell lesions. The lesion effects on choice were not the consequence of impaired social or non‐social motivation, anxiety or sensory or motor function, suggesting that they reflected a genuine deficit in social reward revaluation. These results highlight the role of nucleus accumbens shell in revaluating food rewards to match a conspecific's preferences. [ABSTRACT FROM AUTHOR]

The relationship between social behaviour and the microbiome is known to be reciprocal. Research in wild animal populations, particularly in primate social groups, has revealed the role that social interactions play in microbial transmission, whilst studies in laboratory animals have demonstrated that the gut microbiome can affect multiple aspects of behaviour, including social behaviour. Here we explore behavioural variation in a non-captive animal population with respect to the abundance of specific bacterial genera. Social behaviour based on grooming interactions is assessed in a population of rhesus macaques (Macaca mulatta), and combined with gut microbiome data. We focus our analyses on microbiome genera previously linked to sociability and autistic behaviours in rodents and humans. We show in this macaque population that some of these genera are also related to an individual's propensity to engage in social interactions. Interestingly, we find that several of the genera positively related to sociability, such as Faecalibacterium, are well known for their beneficial effects on health and their anti-inflammatory properties. In contrast, the genus Streptococcus, which includes pathogenic species, is more abundant in less sociable macaques. Our results indicate that microorganisms whose abundance varies with individual social behaviour also have functional links to host immune status. Overall, these findings highlight the connections between social behaviour, microbiome composition, and health in an animal population. [ABSTRACT FROM AUTHOR]

Fishes include some of the most threatened vertebrate species globally. As such, efforts to effectively conserve and manage fish populations and their habitats are vast. Here, we present conceptual tools from behavioural ecology to establish a framework for studies of fish conservation and management, connecting questions relevant to managers and practitioners with behavioural theories and methodologies. We apply predictions developed from a theory to diet choice, patch use, habitat selection, movement, and social behaviours. We present questions and issues in fisheries management and conservation for which theory, hypotheses, and methodologies would be both novel and complementary to current assessment strategies or conservation efficacy studies. In each case, theory approaches the ecological trade‐offs associated with a given behavioural trait through the lens of adaptations and fitness implications—the foundational principles of behavioural ecology. We show key methodologies used to effectively apply behavioural theory to specific hypotheses relevant to a given management question. We then compile the conceptual and methodological approaches to assemble a toolkit through which fisheries managers may assess, for example, habitat selection behaviours via novel study designs and/or new ways of interpreting commonly collected data (e.g., distribution and abundance relative to habitat type). Finally, we propose training of aquatic and marine natural resource specialists and conservation agency fish biologists be complemented with behavioural ecology theories and methodologies.

Social Innovation (SI) is considered a key lever for supporting climate action and decarbonization. In addition to the adoption of technological innovations, novel social practices can lead to the reconfiguration of socio-technical systems toward more democratic energy transitions and heightened civic participation for climate action. Several frameworks and cases of social innovation for climate neutrality are described in the academic literature; however, this rich body of knowledge is scattered across different fields and the actual relevance of social innovation for climate is rarely measured. A core challenge remains regarding the systematic assessment of social innovation's contribution to decarbonization. With the aim of developing a comprehensive framework for potentially assessing social innovations, the extant literature is mapped and the following key dimensions of social innovation for climate neutrality are derived: context, input (or resources), social innovation activities (capacity building, types of SI initiatives and scaling), and results (immediate outputs, medium-term outcomes, long-term impact toward wellbeing). The framework has both theoretical and practical relevance: it provides a structured pathway of social innovation mechanisms and related assessment categories, which can be deployed showing evidence of social innovation effects, gaining insights for actions' improvements, as well as informing policy-making.

Social structure can regulate information and pathogen transmission via social contact or proximity, which ultimately affects individual fitness. In theory, the social relationships that mediate information transmission also favor the spread of socially‐transmitted pathogens, creating a tradeoff between them. However, the mechanisms underlying the development and maintenance of individual relationships under such pressures remain underexplored. Here, we outline the evolutionary mechanisms of social transmission while presenting evidence that network plasticity results from individuals navigating between the costs and benefits of social relationships. We provide perspectives for the development of the field, considering this underexplored social tradeoff and the evolutionary processes underlying it. We believe that the study of the social transmission tradeoff has the potential to become a major new research direction in behavioural and evolutionary ecology. [ABSTRACT FROM AUTHOR]

Aims: We aim to evaluate the frequency and outcomes of workplace incivility in healthcare for nursing management. Background: Incivility in the workplace is a significant problem that is important to nurse managers, as it goes directly against the fundamental values and ethics of providing high‐quality care to patients. The Joint Commission (2021) and the American Nurses Credentialing Center have called on healthcare organizations to identify and intervene in the problem of workplace incivility. Evaluation: Studies included in this scoping review were those that measured and analysed the frequency and outcomes of workplace incivility in healthcare. Four databases were searched, and 28 articles were reviewed. Evaluation was based on general quality, including study characteristics, instruments, and statistical analyses. Key issues: Studies used a quasi‐experimental design, and most focused on the Registered Nurse population. The Workplace Incivility Scale was the most commonly used instrument to measure workplace incivility frequency. The most frequently studied work‐related outcomes were burnout, satisfaction, and turnover. Conclusions: Although the frequency of workplace incivility in healthcare is not clear, its consequences are substantial. Multiple studies have revealed significant relationships between workplace incivility and work‐related outcomes that are important to nurse managers. Research is needed on non‐nursing healthcare professionals, and validation studies are needed on instruments used to measure workplace incivility frequency. Implications for Nursing Management: The findings of this review can help nurse managers better understand the phenomenon, frequency, and impact of workplace incivility in the healthcare setting and move toward addressing the problem of workplace incivility among nurses and other healthcare professionals.

Scent marks deposited as semiochemical signals are a primary mode of communication for a broad range of mammal species. Such scent signals are often deposited at specific, frequently visited marking sites called latrines. Despite descriptions of widespread latrine use by numerous mammal species, detailed understanding of site visit rates and latrine function is lacking. Here we report for the first time a quantitative assessment of scent-marking behaviours that represent interpack olfactory communication by African wild dogs, Lycaon pictus , at latrines visited by multiple resident neighbouring packs, hereafter called a 'shared marking site' (SMS). We show that multiple packs visited specific SMSs frequently and regularly throughout the year, with a notable decrease in visits during the 3-month denning season coinciding with a contraction in range size. In addition to resident neighbouring packs, dispersing individuals visited and scent-marked at SMSs, suggesting that latrines function at least in part as sites communicating information about residence and possibly reproductive status. Further detailed investigation of the relevance of latrine use to territorial behaviour, ranging, habitat use and dispersal in this species is required, particularly as it may have direct applied conservation implications for this wide-ranging but territorial endangered species. • African wild dogs repeatedly visit and scent-mark at shared marking sites (SMSs). • Visits decrease during the denning season, coinciding with a range contraction. • SMSs are implicated in territorial advertisement. • SMSs are closer to roads than are controls and avoid grassland and permanent water.

Sexual conflict is ubiquitous across the animal kingdom and often involves costly sexual harassment of females by males. An overlooked outcome of sexual conflict is its potential impact on social behaviour. Due to their seemingly harmful mode of copulation (traumatic insemination) and tendency to form aggregations, bed bugs are an ideal model for studying the social implications of sexual conflict. Repeated traumatic inseminations are known to reduce some aspects of female fitness, so we expected the benefits to males and the high costs for females of frequent mating to result in divergent social preferences between the sexes. To examine the impact of sexual harassment on social structure, we devised a novel experimental arena with either two shelters or 12 shelters and continuously tracked sexual and social interactions between individually marked bed bugs over 6 days. By constructing aggregation networks, we examined whether female bed bugs occupied more peripheral network positions compared to males as well as whether females preferentially associated with other females as a strategy to reap the benefits of group living while mitigating the costs of unsolicited sexual attention. We found no evidence that females shape their social environment to evade associating with males. However, when tested individually in a follow-up experiment, mated females showed a strong preference for social cues from females over social cues from males. Our results therefore suggest that males and females may be in conflict over the composition of social associations and highlight the importance of both examining behaviour at the individual level and tracking larger groups of freely interacting populations in more complex environments. • Sexual conflict may differentially influence social behaviour of females and males. • We constructed bed bug social networks to see whether females socially evade males. • Aggregation networks did not show female avoidance through decreased sociality. • Social networks were also not assorted by sex. • However, females preferred social cues associated with other females over males.

Human has been evolving in a natural environment over a long time; thus, he is habitual to adapt it. Green spaces are obligatory landscapes in an urban structure that provide a natural environment and accelerate other life events. In contrast, unplanned urbanization, and conversion from green to grey structures have damaged natural environmental resources. Studies through different angles have highlighted the importance of urban green spaces for human well-being but now need to identify their role according to the potential. The demands of urban green spaces may differ with the change of population size, types of grey structure, urban expansion, the altitude of the place, and geographical location. Therefore, this systematic review aims to analyse the significance of urban green spaces for human well-being. The study opted for a systematic process during the selection and organization of studies for this review. After analysing, 46 studies were finalized with the consensus of three review authors. Accordingly, literature was analysed under the central theme of "Urban Green Spaces for Human Well-being." Human Well-being was assessed under six sub-themes; physical, psychological, mental, social, subjective, and environmental well-being. The review concluded that urban green spaces are the primary pillar for a sustainable urban place and human well-being due to highly positive and positive correlations. Moreover, the study did not find any demarcation line between green spaces and grey structures according to any specific need. Therefore, the study suggested that the role of urban green spaces for human well-being should be analysed according to their potential and required optimal ratio under different communities' urban specific environments and social behaviour.

The importance of social and spatial structuring of wildlife populations for disease spread, though widely recognized, is still poorly understood in many host‐pathogen systems. In particular, system‐specific kin relationships among hosts can create contact heterogeneities and differential disease transmission rates. Here, we investigate how distance‐dependent infection risk is influenced by genetic relatedness in a novel host‐pathogen system: wild boar (Sus scrofa) and African swine fever (ASF). We hypothesized that infection risk would correlate positively with proximity and relatedness to ASF‐infected individuals but expected those relationships to weaken with the distance between individuals due to decay in contact rates and genetic similarity. We genotyped 323 wild boar samples (243 ASF‐negative and 80 ASF‐positive) collected in north‐eastern Poland in 2014–2016 and modelled the effects of geographic distance, genetic relatedness and ASF virus transmission mode (direct or carcass‐based) on the probability of ASF infection. Infection risk was positively associated with spatial proximity and genetic relatedness to infected individuals with generally stronger effect of distance. In the high‐contact zone (0–2 km), infection risk was shaped by the presence of infected individuals rather than by relatedness to them. In the medium‐contact zone (2–5 km), infection risk decreased but was still associated with relatedness and paired infections were more frequent among relatives. At farther distances, infection risk further declined with relatedness and proximity to positive individuals, and was 60% lower among un‐related individuals in the no‐contact zone (33% in10–20 km) compared among relatives in the high‐contact zone (93% in 0–2 km). Transmission mode influenced the relationship between proximity or relatedness and infection risk. Our results indicate that the presence of nearby infected individuals is most important for shaping ASF infection rates through carcass‐based transmission, while relatedness plays an important role in shaping transmission rates between live animals.

Efforts to challenge mental health-related stigma have been limited by an insufficient conceptualization of the problem space. As is common in health communication, practitioners have neglected the multiple tacit understandings the public embody in everyday life. Using the example of our recent research into the public’s social representations of mental health and illness, in this paper, we will work through the theoretical-methodological considerations involved in how we approached expanding the problem space. Using social theory, we tailored thematic analysis and natural language processing techniques to examine the public’s polyphasic sense-making processes. The approach is novel, as it diverges from standard methods in understanding health communication and the possibilities for behaviour change. Instead, we root our approach in a dynamic and relational epistemology to iteratively reveal in greater complexity some of the contents and processes that sustain mental health-related stigma.

Understanding how subordinate altruistic roles arise among genetically similar individuals is critical to understanding the evolution of animal societies. In particular, maternal manipulation of offspring resources is an understudied process by which mothers may produce cooperative phenotypes among offspring. Mothers of the small carpenter bee Ceratina calcarata frequently produce a smaller underprovisioned daughter, known as the dwarf eldest daughter (DED) in the first cell of their nests. This DED is more subordinate and more easily coerced into helping siblings, aiding mothers in guarding and supplemental foraging and feeding of adult siblings. Colonies of these bees thus offer a unique opportunity to study the indirect effect of nutritional manipulation on behaviour, in particular mutual tolerance. We hypothesized that aggression would be greatest in the presence of DEDs, as they are actively coerced by their mothers to forage and feed their siblings. Here we experimentally added nutrition to the first cells of C. calcarata observation nests to test the effect of nutritional manipulation on colony intranidal behaviour. Using infrared cameras, control (N = 13) and nutritionally supplemented nests (N = 13) were observed for a total of 607.5 h. Behaviours were scored and categorized. Although aggression was unaffected, avoidant behaviour was greater in nutritionally supplemented nests. This study is the first experiment examining the effect of nutritional manipulation on intranidal behaviour in a stem nesting bee. Our results indicate that maternal manipulation and nutritional deprivation by mothers is critical to the production of mutual tolerance and division of labour. • We test effects of nutritional manipulation on mutual tolerance in C. calcarata. • Maternal manipulation of offspring nutrition influenced colony behaviour. • Avoidance behaviour increased in colonies with nutritional supplementation. • Control colonies with naturally underprovisioned daughters were more tolerant. • Mutual tolerance is among the most rudimentary social requirements.

The neuropeptide arginine‐vasopressin (AVP) has long been implicated in the regulation of social behaviour and communication, but the sources of AVP release relevant for behaviour have not been precisely determined. Ablations of the sexually dimorphic AVP cells within the bed nucleus of the stria terminalis (BNST), which are more numerous in males, affect social behaviour differently in males and females. However, it is unknown whether these behavioural effects are caused by a reduction of AVP or of other factors associated with these cells. To test the role of AVP specifically, we used an shRNA viral construct to knock down AVP gene expression within the BNST of wild‐type male and female mice, using scrambled sequence virus as a control, and evaluated subsequent changes in social behaviours (social investigation, ultrasonic vocalization (USV), scent marking, copulation, and aggression), or anxiety‐like behaviours (elevated plus maze). We observed that, in males, knockdown of AVP expression in the BNST strongly reduced investigation of novel males, aggressive signalling towards other males (tail rattling, USV), and copulatory behaviour, but did not alter attack initiation, other measures of social communication, or anxiety‐like behaviours. In females, however, BNST AVP knockdown did not alter any of these behaviours. These results point to differential involvement of AVP derived from the BNST in social behaviour.

Objectives: Psychosis is characterized by paranoid delusions, social withdrawal, and distrust towards others. Trust is essential for successful social interactions. It remains unknown which aspects of social functioning are associated with reduced trust in psychosis. Therefore, we investigated the association between social behaviour, trust, and its neural correlates in a group of individuals with psychotic symptoms (PS‐group), consisting of first episode psychosis patients combined with individuals at clinical high risk. Methods: We compared 24 PS individuals and 25 healthy controls. Affect and social withdrawal were assessed using the Experience Sampling Method. Trust was measured during functional magnetic resonance imaging (fMRI) scanning, using a trust game with a cooperative and unfair counterpart. Results: The PS‐group showed lower baseline trust compared to controls and reported less positive and more negative general affect. Social withdrawal did not differ between the groups. Social withdrawal and social reactivity in affect (i.e., changes in affect when with others compared to when alone) were not associated with trust. On the neural level, in controls but not in the PS‐group, social withdrawal was associated with caudate activation during interactions with an unfair partner. An increase in positive social reactivity, was associated with reduced insula activation in the whole sample. Conclusions: Social withdrawal and social reactivity were not associated with reduced initial trust in the PS‐group. Like controls, the PS‐group showed a positive response in affect when with others, suggesting a decrease in emotional distress. Supporting patients to keep engaging in social interactions, may alleviate their emotional distress. Practitioner points: Individuals with psychotic symptoms show reduced initial trust towards unknown others.Trust in others is not associated with social withdrawal and reported affect when with others, nor when alone.Like controls, individuals with psychotic symptoms showed reduced negative affect and increased positive affect when with others compared to when alone.We emphasize to support individuals with psychotic symptoms to keep engaging in social interactions, given it may reduce social withdrawal and alleviate their emotional distress.

Inter-brain synchrony occurs between individuals who feel connected socially, but how synchrony relates to felt connectedness under naturalistic social interaction has remained enigmatic. We hypothesized that inter-brain synchrony between naturally interacting individuals might be associated with the internalization of a social identity, a link between an individual's personal identity and the social group to which the individual belongs. A convenience sample of sixty participants were split into dyads and interacted naturalistically on a social task. Through mapping EEG oscillatory waveforms onto a conceptual model categorizing the formation of a social identity within a naturalistic conversation, greater inter-brain synchrony was observed in the emergent stage within the formation of a social identity compared to earlier stages, where a social identity was not present. We provide evidence for greater neural synchrony related to higher socio-psychological connectedness during the development of social identity under naturalistic social interaction., (© 2024 The Author(s).

All animals exhibit some combination of spatial and social behaviours. A diversity of interactions occurs between such behaviours, producing emergent phenomena at the spatial-social interface . Untangling and interrogating these complex, intertwined processes can be vital for identifying the mechanisms, causes and consequences of behavioural variation in animal ecology. Nevertheless, the integrated study of the interactions between spatial and social phenotypes and environments (at the spatial-social interface) is in its relative infancy. In this theme issue, we present a collection of papers chosen to expand the spatial-social interface along several theoretical, methodological and empirical dimensions. They detail new perspectives, methods, study systems and more, as well as offering roadmaps for applied outputs and detailing exciting new directions for the field to move in the future. In this Introduction, we outline the contents of these papers, placing them in the context of what comes before, and we synthesize a number of takeaways and future directions for the spatial-social interface. This article is part of the theme issue 'The spatial-social interface: a theoretical and empirical integration'.

Animals simultaneously navigate spatial and social environments, and their decision-making with respect to those environments constitutes their spatial (e.g. habitat selection) and social (e.g. conspecific associations) phenotypes. The spatial-social interface is a recently introduced conceptual framework linking these components of spatial and social ecology. The spatial-social interface is inherently scale-dependent, yet it has not been integrated with the rich body of literature on ecological scale. Here, we develop a conceptual connection between the spatial-social interface and ecological scale. We propose three key innovations that incrementally build upon each other. First, the use-availability framework that underpins a large body of literature in behavioural ecology can be used in analogy to the phenotype-environment nomenclature and is transferable across the spatial and social realms. Second, both spatial and social phenotypes are hierarchical, with nested components that are linked via constraints-from the top down-or emergent properties-from the bottom up. Finally, in both the spatial and social realms, the definitions of environment and phenotype depend on the focal scale of inquiry. These conceptual innovations cast our understanding of the relationships between social and spatial dimensions of animal ecology in a new light, allowing a more holistic understanding and clearer hypothesis development for animal behaviour. This article is part of the theme issue 'The spatial-social interface: a theoretical and empirical integration'.

Domestic cats use visual cues to communicate with conspecifics and humans. This includes the position and movement of the tail. The tail up signal (i.e. tail held vertically with the tip curled) has been identified as a friendly greeting signal between cats and from cats to humans. We present here a report of two cats unable to display the classic tail up signal due to Spitz-like (curled) tail characteristics, a morphology not previously reported in the scientific literature. The cats, a British Shorthair (Mn, 2 y) and Domestic Longhair (Fn, 8.5 y), belonged to different households and were participants in a study of intraspecific social interactions. Video recordings show the cats displaying normal tail movements (waving, swishing, twitching) and position when the tail was hanging down. However, once the tail was raised to a vertical position, it immediately curled over the back. This Spitz-like tail posture was displayed both when greeting people and other cats. It had reportedly been present since adoption. There was no underlying medical history of injury or pain to indicate this was an acquired state. We suggest this Spitz-like tail is a spontaneously occurring anomaly, that does not seem to noticeably impair the cats' communicative abilities, as normal affiliative behaviours were observed during interactions with the cohoused cat. We discuss the significance of this finding in relation to the formation of social bonds and the signalling of affiliative intent., Competing Interests: Declaration of Competing Interest None of the authors have any financial or personal relationships that could inappropriately influence or bias the content of the paper., (Copyright © 2024 Elsevier Ltd.

Individuals of many species prefer to associate with familiar conspecifics from their established social group over unfamiliar conspecifics. Such familiarity preferences are thought to be adaptive and have been documented widely in many social fishes. Zebrafish (Danio rerio) are extensively studied, highly social fish that form stable shoals in the wild, however there is only mixed evidence for familiarity preferences in this species. Here, we test how a small variation in experimental design can influence preferences for familiar conspecifics in D. rerio by varying the distance between two stimulus shoals of fish in a shoaling choice paradigm. Individual subjects tested for their preference to shoal with familiar or unfamiliar groups of conspecifics showed a preference for familiar fish when the two shoals were 30 cm apart, but not when they were 45 or 60 cm apart. Thus, choice tests can be used to detect familiarity preferences in D. rerio, but only when alternate shoals are close together, as increased intershoal distances seemingly prevent subjects from displaying their preference. Longer distances may inhibit preference behavior due to the higher risk of crossing between shoals, alternatively subjects may be unable to reliably discern distinguishing cues of familiarity when the shoals are further apart. Our results demonstrate that while familiarity preferences exist in D. rerio, experimental test design is critical for detecting and measuring these successfully., (© 2024 The Author(s).

The errors young children make when recognising others' emotions may be systematic over-identification biases and may partially explain the challenges some have socially. These biases and associations may be differential by emotion. In a sample of 871 ethnically and racially diverse preschool-aged children (i.e. 33-68 months; 49% Hispanic/Latine, 52% Children of Colour), emotion recognition was assessed, and scores for accuracy and bias were calculated by emotion (i.e. anger, sad, happy, calm, and fear). Child and family characteristics and teacher-reported social behaviour were also collected. Multilevel structural equation modelling revealed emotion-specific recognition accuracies varied between 36 and 65% whereas biases varied between 4 and 13%. Anger was the strongest bias followed by sad, happy, fear, and calm, in contrast to the pattern for accuracy - happy, sad, angry, fear, and calm. More variance was explained in emotion-specific recognition accuracies by child and family characteristics - 7-38% - than biases - 3-7%. Negatively-valanced emotion recognition biases associated with positively-valanced accuracies, and positively-valued emotion recognition biases associated with negatively-valued accuracies. Biases did not have meaningful associations with social behaviour. This study highlights that children's emotion recognition errors may partially be systematic, but future studies are needed to understand the underlying cognitive mechanisms.

Social camouflaging (SC) is a set of behaviors used by autistic people to assimilate with their social environment. Using SC behaviours may put autistic people at risk for poor mental health outcomes. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the goal of this systematic review was to investigate the development of SC and inform theory in this area by outlining the predictors, phenotype, and consequences of SC. This review fills a gap in existing literature by integrating quantitative and qualitative methodologies, including all gender identities/age groups of autistic individuals, incorporating a large scope of associated factors with SC, and expanding on theory/implications. Papers were sourced using Medline, PsycInfo, and ERIC. Results indicate that self-protection and desire for social connection motivate SC. Camouflaging behaviors include compensation, masking, and assimilation. Female individuals were found to be more likely to SC. Additionally, this review yielded novel insights including contextual factors of SC, interpersonal relational and identity-related consequences of SC, and possible bidirectional associations between SC and mental health, cognition, and age of diagnosis. Autistic youth and adults have similar SC motivations, outward expression of SC behavior, and experience similar consequences post-camouflaging. Further empirical exploration is needed to investigate the directionality between predictors and consequences of SC, and possible mitigating factors such as social stigma and gender identity.

Season length and its associated variables can influence the expression of social behaviours, including the occurrence of eusociality in insects. Eusociality can vary widely across environmental gradients, both within and between different species. Numerous theoretical models have been developed to examine the life history traits that underlie the emergence and maintenance of eusociality, yet the impact of seasonality on this process is largely uncharacterized. Here, we present a theoretical model that incorporates season length and offspring development time into a single, individual-focused model to examine how these factors can shape the costs and benefits of social living. We find that longer season lengths and faster brood development times are sufficient to favour the emergence and maintenance of a social strategy, while shorter seasons favour a solitary one. We also identify a range of season lengths where social and solitary strategies can coexist. Moreover, our theoretical predictions are well matched to the natural history and behaviour of two flexibly eusocial bee species, suggesting that our model can make realistic predictions about the evolution of different social strategies. Broadly, this work reveals the crucial role that environmental conditions can have in shaping social behaviour and its evolution and it underscores the need for further models that explicitly incorporate such variation to study the evolutionary trajectories of eusociality.

Fluctuations in estradiol levels at each stage of life in women are considered one of the causes of mental diseases through their effects on the central nervous system. During menopause, a decrease in estradiol levels has been reported to affect the serotonin nervous system and induce depression-like and anxiety symptoms. However, the regulation of brain and behaviour during childhood and adolescence is poorly understood. Moreover, the role of oestrogen receptors α and β in the regulation of the serotonergic nervous system has been reported, but little is known about the involvement of G protein-coupled receptor 30. Therefore, in this study, we used an ovariectomized childhood mouse model to analyse behaviour and investigate the effects on the serotonin nervous system. We showed that ovariectomy surgery at 4 weeks of age, which is the weaning period, induced a decrease in spontaneous locomotor activity during the active period and a preference for novel mice over familiar mice in the three-chamber social test at 10 weeks of age. In addition, the administration of G-1, a protein-coupled receptor 30 agonist, to ovariectomized mice suppressed spontaneous locomotor activity and the preference for novel mice. Furthermore, we demonstrated that childhood ovariectomy induces increased tryptophan hydroxylase gene expression in the raphe nucleus and increased serotonin release in the amygdaloid nucleus, and administration of G-1 ameliorated these effects. Our study suggests that G protein-coupled receptor 30-mediated regulation of serotonin synthesis is involved in changes in activity and social-cognitive behaviour due to decreased estradiol levels during childhood., (© 2024 The Author(s).

Background: Oral and social problems can exacerbate long-term care. Understanding the relationship between social aspects and oral hypofunction can help identify high-risk factors for long-term care., Objective: This study aimed to investigate the social aspects of oral hypofunction among medical outpatients., Methods: This retrospective cross-sectional study included patients who visited an outpatient clinic for frailty. The oral function was assessed using seven items: oral hygiene, occlusal force, masticatory function, tongue-lip motor function, tongue pressure, oral dryness and swallowing function. Participants with three or more functional declines were classified as having 'oral hypofunction'. Social aspects were assessed using 21 items in four categories: general resources, basic social needs, social resources and social behaviours/activities. We analysed the relationship between oral hypofunction and each social aspect., Results: A total of 316 participants (age 78.5 ± 6.4 years) were included, and 128 (41%) had oral hypofunction. Participants with oral hypofunction were significantly more likely to have limited education, require long-term care, not use transportation, depend on others for shopping, not participate in events, lack association membership and not engage in charity or volunteer work. After logistic regression analysis, 'long-term care' and 'no association membership' remained significantly associated with oral hypofunction (odds ratios 2.3, 2.3; 95% CI 1.1-5.0, 1.1-4.7, respectively)., Conclusion: Participants with oral hypofunction faced challenges in 'general resources' and 'social behaviour/activities', which were linked to oral function issues. Future longitudinal studies are necessary to further investigate this relationship., (© 2024 John Wiley & Sons Ltd.)

In recent decades, the integration of horses (Equus ferus) in European rewilding initiatives has gained widespread popularity due to their potential for regulating vegetation and restoring natural ecosystems. However, employing horses in conservation efforts presents important challenges, which we here explore and discuss. These challenges encompass the lack of consensus on key terms inherent to conservation and rewilding, the entrenched culture and strong emotions associated with horses, low genetic diversity and high susceptibility to hereditary diseases in animals under human selection, as well as insufficient consideration for the social behaviour of horses in wild-living populations. In addition, management of wild-living horses involves intricate welfare, ethics and legislative dimensions. Anthropocentric population-control initiatives may be detrimental to horse group structures since they tend to prioritise individual welfare over the health of populations and ecosystems. To overcome these challenges, we provide comprehensive recommendations. These involve a systematic acquisition of genetic information, a focus on genetic diversity rather than breed purity and minimal veterinary intervention in wild-living populations. Further, we advise allowing for natural top-down and bottom-up control - or, if impossible, simulating this by culling or non-lethal removal of horses - instead of using fertility control for population management. We advocate for intensified collaboration between conservation biologists and practitioners and enhanced communication with the general public. Decision-making should be informed by a thorough understanding of the genetic makeup, common health issues and dynamics, and social behaviour in wild-living horse populations. Such a holistic approach is essential to reconcile human emotions associated with horses with the implementation of conservation practices that are not only effective but also sustainable for the long-term viability of functional, biodiverse ecosystems, while rehabilitating the horse as a widespread wild-living species in Europe., (© 2024 The Author(s).

Motor function is a critical aspect of social behaviour in a wide range of taxa. The transcription factor forkhead box P2 (FoxP2) is well studied in the context of vocal communication in humans, mice and songbirds, but its role in regulating social behaviour in other vertebrate taxa is unclear. We examined the distribution and activity of FoxP2-positive neurons in tadpoles of the mimic poison frog ( Ranitomeya imitator ). In this species, tadpoles are reared in isolated plant nurseries and are aggressive to other tadpoles. Mothers provide unfertilized egg meals to tadpoles that perform a begging display by vigorously vibrating back and forth. We found that FoxP2 is widely distributed in the tadpole brain and parallels the brain distribution in mammals, birds and fishes. We then tested the hypothesis that FoxP2-positive neurons would have differential activity levels in begging or aggression contexts compared to non-social controls. We found that FoxP2-positive neurons showed increased activation in the striatum and cerebellum during begging and in the nucleus accumbens during aggression. Overall, these findings lay a foundation for testing the hypothesis that FoxP2 has a generalizable role in social behaviour beyond vocal communication across terrestrial vertebrates.

Purpose – This research aims to measure the effects of the peace education program on the social and emotional behaviours of preschool children in the Sultanate of Oman. Children should be equipped with basic values, such as respecting the efforts and ideas of others, forming a comprehensive and positive relationship with people, possessing the skills of empathy, and resolving conflicts in peaceful ways. Design/methods/approach – The researcher adopted the quasi-experimental approach, and the current study presented the Peace Education Program (PEP) for children aged 4–6 years in the Sultanate of Oman. The participants consisted of 40 children in the experimental group and 40 children in the control group. The researcher used a scale with picture choice questions containing two pictures per question to measure the behaviours of children before and after the treatments. The peace education program for the study also included 28 training sessions that were presented for 15 weeks at a duration of one hour per session. Findings – The current study results also favoured the experimental group, as an improvement in their social behaviour was observed after joining the program. Research implications/limitations – The research demonstrates that peace is a key prerequisite for developing a balanced life, especially in childhood. The results may be of great significance in measuring and improving children's behaviour through (PEP). Practical implications – The study findings may likely be fruitful to Oman's pupils, educators, curriculum designers, and educational policy-makers. Originality/value – This study has been successful in focusing on some aspects of growth and behaviour enhancement in children. Paper type Research paper

Water wells are the most unique finds from the Early Neolithic period in Central Europe. These features provide unusual insight into societies and their settlements, as well as into the water management process. This article presents the updated results of material analyses and excavations of Early Neolithic wells at Mohelnice, Brno-Bohunice and Uničov in Moravia, Czech Republic. We studied the possibilities of the spatial and temporal distribution of wells on the example of these settlements. The social relation between the large longhouses and the wells in their immediate neighbourhood has not been proven. On the contrary, they could have been communal wells, serving the inhabitants of the entire settlement. Moreover, it turned out that in the Moravian region, geomorphological conditions were a key factor for choosing the location to build a well. By comparing radiocarbon dates, we estimated the time span of the existence of wells with respect to each other and to the settlements. Sealing and repairs of the well constructions prove that the first farmers maintained the wells over a long period of time. Studies of the well’s vertical sections shed light on its usage and decline; intentional backfilling of the well seems to have been common. Water management covered an entire cycle of activities, including the making of wooden buckets, which were mainly used for the pulling of water from wells.

The relationship between social behaviour and the microbiome is known to be reciprocal. Research in wild animal populations, particularly in primate social groups, has revealed the role that social interactions play in microbial transmission, whilst studies in laboratory animals have demonstrated that the gut microbiome can affect multiple aspects of behaviour, including social behaviour. Here we explore behavioural variation in a non-captive animal population with respect to the abundance of specific bacterial genera. Social behaviour based on grooming interactions is assessed in a population of rhesus macaques (Macaca mulatta), and combined with gut microbiome data. We focus our analyses on microbiome genera previously linked to sociability and autistic behaviours in rodents and humans. We show in this macaque population that some of these genera are also related to an individual’s propensity to engage in social interactions. Interestingly, we find that several of the genera positively related to sociability, such as Faecalibacterium, are well known for their beneficial effects on health and their anti-inflammatory properties. In contrast, the genus Streptococcus, which includes pathogenic species, is more abundant in less sociable macaques. Our results indicate that microorganisms whose abundance varies with individual social behaviour also have functional links to host immune status. Overall, these findings highlight the connections between social behaviour, microbiome composition, and health in an animal population.

Oxytocin (OT) and the OT receptor occupy essential roles in our current understanding of mammalian evolution, survival, sociality and reproduction. This narrative review examines the hypothesis that many functions attributed to OT can be traced back to conditions on early Earth, including challenges associated with managing life in the presence of oxygen and other basic elements, including sulfur. OT regulates oxidative stress and inflammation especially through effects on the mitochondria. A related nonapeptide, vasopressin, as well as molecules in the hypothalamic–pituitary–adrenal axis, including the corticotropin-releasing hormone family of molecules, have a broad set of functions that interact with OT. Interactions among these molecules have roles in the causes and consequence of social behaviour and the management of threat, fear and stress. Here, we discuss emerging evidence suggesting that unique properties of the OT system allowed vertebrates, and especially mammals, to manage over-reactivity to the 'side effects' of oxygen, including inflammation, oxidation and free radicals, while also supporting high levels of sociality and a perception of safety.

Oxytocin modulates social behaviour across diverse vertebrate taxa, but the precise nature of its effects varies across species, individuals and lifetimes. Contributing to this variation is the fact that oxytocin's physiological effects are mediated through interaction with diverse neuromodulatory systems and can depend on the specifics of the local circuits it acts on. Furthermore, those effects can be influenced by both genetics and experience. Here we discuss this complexity through the lens of a specific neuromodulatory system, endocannabinoids, interacting with oxytocin in the nucleus accumbens to modulate prosocial behaviours in prairie voles. We provide a survey of current knowledge of oxytocin–endocannabinoid interactions in relation to social behaviour. We review in detail recent research in monogamous female prairie voles demonstrating that social experience, such as mating and pair bonding, can change how oxytocin modulates nucleus accumbens glutamatergic signalling through the recruitment of endocannabinoids to modulate prosocial behaviour toward the partner. We then discuss potential sex differences in experience-dependent modulation of the nucleus accumbens by oxytocin in voles based on new data in males. Finally, we propose that future oxytocin-based precision medicine therapies should consider how prior social experience interacts with sex and genetics to influence oxytocin actions.
