Unfamiliarity generates costly aggression in interspecific avian dominance hierarchies.

Dominance hierarchies often form between species, especially at common feeding locations. Yet, relative to work focused on the factors that maintain stable dominance hierarchies within species, large-scale analyses of interspecific dominance hierarchies have been comparatively rare. Given that interspecific behavioral interference mediates access to resources, these dominance hierarchies likely play an important and understudied role in community assembly and behavioral evolution. To test alternative hypotheses about the formation and maintenance of interspecific dominance hierarchies, we employ an large, participatory science generated dataset of displacements observed at feeders in North America in the non-breeding season. Consistent with the hypothesis that agonistic interference can be an adaptive response to exploitative competition, we find that species with similar niches are more likely to engage in costly aggression over resources. Among interacting species, we find broad support for the hypothesis that familiarity (measured as fine-scale habitat overlap) predicts adherence to the structure of the dominance hierarchy and reduces aggression between species. Our findings suggest that the previously documented agonistic hierarchy in North American birds emerges from species-level adaptations and learned behaviors that result in the avoidance of costly aggression.

The ability to inhibit impulses is related to social behavior in long-tailed macaques.

Performance in cognitive tasks has been linked to differences in species' social organization, yet to understand its function its relationship to within-species variation in behavior should also be explored. One important cognitive capacity, the ability to inhibit impulses, is typically better in egalitarian than despotic primate species and in primate species with strong fission-fusion dynamics. A different line of research indicates that a high ability to inhibit impulses is related to less aggressive behavior and more socio-positive behavior. However, within species the relationship between performance on cognitive inhibition tasks and variation in social behavior remains to be explored. Here we investigate how performance in a typical inhibition task in cognitive research is related to aggressive and socio-positive behavior in despotic long-tailed macaques. Twenty individuals living in two naturalistic mixed-sex groups were tested with the Plexiglass Hole Task. Aggressive behavior and three types of socio-positive behavior (neutral/friendly approaches, socio-positive signaling, and grooming others) among group members were measured. Individuals differed in their ability to inhibit impulses. Individuals that were not good at inhibiting impulses showed higher rates of aggressive behavior, but also more socio-positive signals, whereas inhibition was not related to neutral/friendly approaches and grooming. These results confirm the positive link between impulsiveness and aggression. In addition, the results indicate that some social-positive behavior may be enhanced when inhibition is limited. In this species, benefits potentially derived from aggression and socio-positive signals match a low ability to inhibit impulses, suggesting that a low ability to inhibit impulses may actually be advantageous. To understand differences between species in cognitive skills, understanding the benefits of variation in a cognitive capacity within a species is crucial.

Winner-loser effects improve social network efficiency between competitors with equal resource holding power.

Animal societies are structured of dominance hierarchy (DH). DH can be viewed as networks and analyzed by graph theory. We study the impact of state-dependent feedback (winner-loser effect) on the emergence of local dominance structures after pairwise contests between initially equal-ranking members (equal resource-holding-power, RHP) of small and large social groups. We simulated pairwise agonistic contests between individuals with and without a priori higher RHP by Monte-Carlo-method. Random pairwise contests between equal-ranking competitors result in random dominance structures ('Null variant') that are low in transitive triads and high in pass along triads; whereas state-dependent feedback ('Winner-loser variant') yields centralized 'star' structured DH that evolve from competitors with initially equal RHP and correspond to hierarchies that evolve from keystone individuals. Monte-Carlo simulated DH following state-dependent feedback show motif patterns very similar to those of a variety of natural DH, suggesting that state-dependent feedback plays a pivotal role in robust self-organizing phenomena that transcend the specifics of the individual. Self-organization based on state-dependent feedback leads to social structures that correspond to those resulting from pre-existing keystone individuals. As the efficiency of centralized social networks benefits both, the individual and the group, centralization of social networks appears to be an important evolutionary goal.

Spanish Adaptation of the Support for Economic Inequality Scale (S-SEIS).

BACKGROUND: This study presents the adaptation and evidence of the validity of the Spanish version of the Support for Economic Inequality Scale (S-SEIS). This measure evaluates people's tendency to have positive attitudes toward economic inequality. METHOD: Two correlational studies were conducted, one exploratory ( N = 619) and one confirmatory ( N = 562). RESULTS: S-SEIS showed good reliability in both studies. The factorial analysis showed a one-factor structure in Study 1 that was confirmed in Study 2. We also found a relationship between S-SEIS and other extensively used measures of attitudes toward inequality, such as intolerance toward inequality. S-SEIS positively correlates with belief in a just world, social dominance orientation (SDO), economic system justification (ESJ), institutional trust, and perceived democracy; it correlates negatively with intolerance toward inequality, perceived inequality, perceived warmth/competence of people in poverty and support for redistribution. CONCLUSIONS: The current research findings suggest that S-SEIS is a valuable instrument for evaluating the support of economic inequality in Spanish samples.

Sex-dependent control of pheromones on social organization within groups of wild house mice.

Dominance hierarchy is a fundamental social phenomenon in a wide range of mammalian species, critically affecting fitness and health. Here, we investigate the role of pheromone signals in the control of social hierarchies and individual personalities within groups of wild mice. For this purpose, we combine high-throughput behavioral phenotyping with computational tools in freely interacting groups of wild house mice, males and females, in an automated, semi-natural system. We show that wild mice form dominance hierarchies in both sexes but use sex-specific strategies, displaying distinct male-typical and female-typical behavioral personalities that were also associated with social ranking. Genetic disabling of VNO-mediated pheromone detection generated opposite behavioral effects within groups, enhancing social interactions in males and reducing them in females. Behavioral personalities in the mutated mice displayed mixtures of male-typical and female-typical behaviors, thus blurring sex differences. In addition, rank-associated personalities were abolished despite the fact that both sexes of mutant mice formed stable hierarchies. These findings suggest that group organization is governed by pheromone-mediated sex-specific neural circuits and pave the way to investigate the mechanisms underlying sexual dimorphism in dominance hierarchies under naturalistic settings.

PsicoQuilombologia: escrevivência de uma psicologia das encruzilhadas em tempos pandêmicos / PsychoQuilombology: writexperience of a psychology of crossroads in pandemic times / PsicoQuilombología: escrivivencia de una psicología de la encrucijada en tiempos pandémicos

O texto é um relato de experiência da participação no Grupo de Estudos psicoQuilombologia ocorrida nos meses de setembro de 2020 a março de 2021, período atravessado pela segunda onda da pandemia de COVID-19 no Brasil. O objetivo do relato é apresentar o conceito-movimento de psicoQuilombologia como uma proposta epistemológica quilombola de agenciamento de cuidado e saúde, com base em uma escuta que se faça descolonial e inspirada no fecundo e ancestral acervo de cuidado dos povos africanos, quilombolas e pretos, preservado e atualizado em nossos quilombos contemporâneos. A metodologia utilizada é a escrevivência, método desenvolvido por Conceição Evaristo que propõe uma escrita em que as vivência e memórias estão totalmente entrelaçadas, imersas e imbricadas com a pesquisa. O resultado das escrevivências dessa pesquisa descortinam que os povos pretos desenvolveram práticas de cuidado e acolhimento às vulnerabilidades do outro, enraizadas no fortalecimento de laços e conexões coletivas de afetos e cuidado mútuos. Práticas de cuidado que articulam memória, ancestralidade, tradição, comunidade, transformação, luta, resistência e emancipação, engendrando modos coletivos de ser e viver. Nas quais cuidar do outro implica tratar suas relações e situar o cuidado como extensão de uma cura que se agencia no coletivo. O trabalho conclui apontando que o cenário pandêmico vigente acentua a pungência de se desenvolver estratégias de cuidado baseadas em epistemologias pretas e quilombolas, valorizando os sentidos de ancestralidade, comunidade, pertencimento e emancipação.(AU)

The text is an experience report of the participation in the psicoQuilombology Study Group that carried out from September 2020 to March 2021, during the second wave of the COVID-19 pandemic in Brazil. The purpose of the report is to introduce the concept-movement of psicoQuilombology as a quilombola epistemological proposal for the development of care and health, based on a decolonial listening and inspired by the rich care collection of African peoples, quilombolas and Blacks, preserved and updated in our contemporary quilombos. The methodology used is writexperience [escrevivências], a method developed by Conceição Evaristo who proposes a writing in that the experiences and memories are totally involved with the research. The result of the writability of this research show that Black people have developed practices of care and acceptance of the other's vulnerabilities, based on the strengthening of ties and collective connections of mutual affection and care. Care practices that mix memory, ancestry, tradition, community, transformation, struggle, resistance and emancipation, outlining collective ways of being and living. The core idea is that taking care of the other means treating your relationships and maintaining care as an extension of a cure that takes place in the collective. The paper concludes by pointing out that the current pandemic scenario demonstrates the urgent need to develop care strategies based on black and quilombola epistemologies, valuing the senses of ancestry, community, belonging and emancipation.(AU)

As imagens dos conjuntos científicos de química: dominância masculina nas representações sobre a ciência / Images of chemistry kits: male dominance in representations of science

Resumo O artigo apresenta o modo como as imagens relativas aos conjuntos de química expressam as representações sobre a predominância do gênero masculino nas brincadeiras que simulam aspectos técnicos, gestuais, de laboratório, criando padrões de conduta que direcionam para a vocação profissional: o ser cientista. Foram privilegiadas as documentações produzidas pelas empresas Gilbert (1920) e Chemcraft (1922), presentes no acervo da Chemical Heritage Foundation (EUA). Discute-se o que Joan Scott chama de organização social da diferença sexual, enquanto são analisadas as ilustrações que privilegiam a dominância do gênero masculino, nas formas de "ser criança", brincando de cientista.

Abstract This article shows how images relating to chemistry sets express the predominance of the male gender in toys that simulate technical, gestural, and laboratory-related aspects of science, creating patterns of conduct towards the professional vocation of being a scientist. Priority is given to documents produced by the companies Gilbert (1920) and Chemcraft (1922) that are kept in the archives of the Chemical Heritage Foundation in the USA. What Joan Scott calls the social organization of sexual difference is discussed and the illustrations are analyzed, demonstrating a predominance of male figures showing how to "be a child," playing at being a scientist.

Bared-teeth displays in bonobos (Pan paniscus): An assessment of the power asymmetry hypothesis.

Facial expressions are key to navigating social group life. The Power Asymmetry Hypothesis of Motivational Emancipation predicts that the type of social organization shapes the meaning of communicative displays in relation to an individual's dominance rank. The bared-teeth (BT) display represents one of the most widely observed communicative signals across primate species. Studies in macaques indicate that the BT display in despotic species is often performed unidirectionally, from low- to high-ranking individuals (signaling submission), whereas the BT display in egalitarian species is usually produced irrespective of dominance (mainly signaling affiliation and appeasement). Despite its widespread presence, research connecting BT displays to the power asymmetry hypothesis outside the Macaca genus remains scarce. To extend this knowledge, we investigated the production of BT in relation to social dominance in dyadic interactions (N = 11,377 events) of 11 captive bonobos (Pan paniscus). Although adult bonobos were more despotic than previously suggested in the literature, BT displays were produced irrespective of dominance rank. Moreover, while adults produced the BT exclusively during socio-sexual interactions, especially during periods of social tension, immature bonobos produced the BT in a wider number of contexts. As such, the results indicate that the communicative meaning of the BT display is consistent with signaling appeasement, especially in periods of social tension. Moreover, the BT display does not seem to signal social status, supporting the prediction for species with a high degree of social tolerance. These results advance our understanding of the origins of communicative signals and their relation to species' social systems.

Reproductive skew, fighting costs and winner-loser effects in social dominance evolution.

Social hierarchies are often found in group-living animals and can be formed through pairwise aggressive interactions. The dominance rank can influence reproductive success (RS) with a skew towards high-ranking individuals. Using game theory, we investigate how the opportunity for differently ranked individuals to achieve RS influences the costs of hierarchy formation and the strength of winner and loser effects. In our model, individuals adjust their aggressive and submissive behaviour towards others through reinforcement learning. The learning is based on rewards and penalties, which depend on relative fighting ability. From individual-based simulations, we determine evolutionary equilibria of traits such as learning rates. We examine situations that differ in the extent of monopolisation of contested RS by dominants and in the proportion of total RS that is contested. The model implements two kinds of fighting costs: a decrease in effective fighting ability from damage (loss of condition) and a risk of mortality that increases with the total accumulated damage. Either of these costs can limit the amount of fighting. We find that individuals form stable dominance hierarchies, with a positive correlation between dominance position and fighting ability. The accumulated costs differ between dominance positions, with the highest costs paid by low or intermediately ranked individuals. Costs tend to be higher in high-skew situations. We identify a 'stay-in, opt-out' syndrome, comprising a range from weaker (stay-in) to stronger (opt-out) winner-loser effects. We interpret the opt-out phenotype to be favoured by selection on lower ranked individuals to opt out of contests over social dominance, because it is more pronounced when more of the total RS is uncontested. We discuss our results in relation to field and experimental observations and argue that there is a need for empirical investigation of the behaviour and reproductive success of lower ranked individuals.

Dominance and social interaction patterns in brown capuchin monkey (Cebus [Sapajus] apella) social networks.

Strong, stable social bonds in primates are characterized by high levels of social affiliation, low levels of aggression, minimal stress, and affiliative reciprocity within the dyad. In relatively well-studied catarrhine monkeys, these bonds tend to form most frequently between kin, animals close in age, and animals close in rank. This results in patterns of affiliation in which kin, similarly aged animals, and like-ranked animals tend to affiliate and patterns of aggression and submission where animals tend to aggress more toward nonkin and closely ranked animals, and submit more toward distantly ranked animals. However, literature on how affiliative and agonistic relationships are organized in platyrrhine primate species like brown capuchin monkeys is limited and conflicting. In this study, we used social network analyses to characterize how age, sex, maternal kinship, and dominance rank relate to the patterns of submissive, aggressive, contact, and grooming interactions in a group of captive brown capuchin monkeys. Like catarrhine monkeys, brown capuchin monkeys showed a steep linear dominance hierarchy, tended to affiliate with kin, similarly aged animals, and like-ranked animals, and tended to aggress more toward nonkin. However, our monkeys showed a pattern of affiliation and grooming down the hierarchy that is inconsistent with grooming up the hierarchy patterns often seen in catarrhine monkey groups, suggesting that brown capuchins do not compete for access to higher ranking social partners. Higher ranking monkeys were most central to the aggression network, and lower ranking monkeys were most central to the submission network. Mid-ranking monkeys were the most central to the contact network, suggesting that they may play an important role in the affiliative cohesion of the group. These results inform our understanding of brown capuchin social behavior specifically, and of how demographic factors relate to social organization in platyrrhine primates generally.

Costs dictate strategic investment in dominance interactions.

Dominance is important for access to resources. As dominance interactions are costly, individuals should be strategic in whom they interact with. One hypothesis is that individuals should direct costly interactions towards those closest in rank, as they have most to gain-in terms of attaining or maintaining dominance-from winning such interactions. Here, we show that male vulturine guineafowl (Acryllium vulturinum), a gregarious species with steep dominance hierarchies, strategically express higher-cost aggressive interactions towards males occupying ranks immediately below themselves in their group's hierarchy. By contrast, lower-cost aggressive interactions are expressed towards group members further down the hierarchy. By directly evaluating differences in the strategic use of higher- and lower-cost aggressive interactions towards competitors, we show that individuals disproportionately use highest-cost interactions-such as chases-towards males found one to three ranks below themselves. Our results support the hypothesis that the costs associated with different interaction types can determine their expression in social groups with steep dominance hierarchies. This article is part of the theme issue 'The centennial of the pecking order: current state and future prospects for the study of dominance hierarchies'.

Política de assistência social e processo de estratégia de hegemonia no Brasil / Social assistance policy and hegemony strategy process in Brazil / Política de asistencia social y proceso de estrategia de hegemonía en Brasil

Com base numa perspectiva dialética e institucional crítica, utilizando o conceito central de Processo de Estratégia de Hegemonia e analisando a bibliografia, discutiremos algumas das razões pelas quais a Assistência Social enquanto um direito do cidadão e um dever do Estado teria sido incluída na Constituição Federal de 1988. Esta é uma política pública cuja função social visa garantir o acesso a direitos sociais básicos imprescindíveis para a sobrevivência de uma parcela significativa da população brasileira. Tais direitos são destinados, principalmente, aos mais pobres, mas também às pessoas denominadas de acordo com o Sistema Único de Assistência Social (Suas) como em situação de vulnerabilidade e risco social. A inclusão da política de Assistência Social na Constituição pode ser considerada uma concessão tácita, uma vez que não foi fruto de uma ampla luta política ou de grande reivindicação popular, diferente do caso da Previdência Social e da Saúde, o que demostra uma contradição essencial, pois o número de possíveis usuários dessa política já justificaria sua existência. Assim como as políticas de segurança alimentar, de trabalho e de acesso à renda, a Assistência Social é uma das principais políticas públicas que tem como objetivo o atendimento dos segmentos mais empobrecidos da população. Ela seria produtora de efeitos concretos focalizados e restritos, e também de efeitos simbólicos importantes, que garantem e legitimam a governança. Pretendemos contribuir para o fortalecimento da Assistência Social como política pública, problematizando alguns de seus impasses.(AU)

From a dialectical and institutional critical perspective based on the central concept of Hegemony Strategy Process and analyzing the bibliography, we'll discuss some grounds for inclusion of Social Assistance in 1988's Federal Constitution as a citizen right and a State obligation. It's a public policy whose social function aims to safeguard the access to basic social rights, indispensable for the survival of a significant portion of the Brazilian population. These rights are mainly destined for poorest people, but also for those that have been designated by the Unified Social Assistance System (USAS) as people in situation of vulnerability and social risk. The inclusion of Social Assistance policy in the Constitution can be considered a tacit concession, since it did not come from a wide political struggle or from a great popular revindication, differently from the Social Security and Health policy, which demonstrates an essential contradiction, since the number of possible users of this policy is enough to justify its existence. The Social Assistance is one of the main public policies, alongside policies of food safety and generation of work and income, that aim to serve the poorest segments of the population. It produces real, focused, and restricted effects alongside important symbolic effects that guarantee and legitimize the governance. We intend to contribute to the strengthening of Social Assistance as a public policy, problematizing some of its impasses.(AU)

Hegemonia do patriarcado numa perspectiva etológica e outros sistemas sociais contemporâneos / Patriarchal hegemony and other social systems: an ethological perspective / L'hégémonie patriarcale et d'autres systèmes sociaux: une perspective éthologique / Hegemonía del patriarcado desde una perspectiva etológica y otros sistemas contemporáneos

Resumo No mundo contemporâneo, o patriarcado se estabeleceu de forma hegemônica, por isso, este estudo tem como propósito investigar hipóteses sobre a origem evolutiva desse sistema, explorar os motivos para tal construção social e discutir a filopatria masculina como possível causa da manutenção da estrutura patriarcal. Por meio de pesquisa bibliográfica e estudos etológicos foi possível analisar os comportamentos, conceitos, origens, padrões e conformações em nível filogenético desse sistema social. Além disso, verifica-se a existência de sociedades contemporâneas que se contrapõem ao patriarcalismo por possuírem organizações matrilineares, matrilocais e matriarcais. Dessa maneira, apesar da hegemonia do sistema patriarcal, essa estrutura não é única e estática, sendo seu dinamismo evidenciado por conformações sociais existentes na contemporaneidade.

Abstract Patriarchy is a hegemonic social system in the contemporary world. This study investigates the evolutionary origins of patriarchy, exploring its basis and whether masculine philopatry acts to maintain the patriarchal structure. An an integrative literature review of ethological studies allowed us to analysing behaviors, concepts, origins, patterns and conformations at the phylogenetic level. Moreover, it verified the existence of current matrilineal and matriarchal communities that oppose patriarchy. Despite its hegemony, patriarchy is neither unique nor static, as evidenced by distinct contemporary social configurations.

Résumé Le patriarcat est u système social hégémonique dans le monde contemporain. Cette étude a pour but d''évaluerse penche sur les origines évolutives du patriarcat, en explorant ses fondements et en examinant si la philopatrie masculine agit pour maintenir la structure patriarcale. Une revue de littérature intégrative des études éthologiques nous a permis d'analyser les comportements, les concepts, les origines, les modèles et la configuration du patriarcat au niveau phylogénétique. De plus, elle a permis de vérifier l'existence de communautés matrilinéaires et matriarcales contemporaines qui s'opposent au patriarcat. Malgré son hégémonie, le patriarcat n'est ni unique ni statique, comme en témoignent les différentes configurations sociales contemporaines.

Resumen En la contemporaneidad, el sistema patriarcal se ha establecido de forma hegemónica. Este estudio tiene como propósito plantear hipótesis sobre el origen evolutivo del patriarcado, explorar los motivos para tal construcción social y discutir la filopatria masculina como posible causa del mantenimiento de la estructura patriarcal. A partir de la investigación bibliográfica y de estudios etológicos ha sido posible hacer un análisis de los comportamientos, conceptos, orígenes, patrones y conformaciones a nivel filogenético de ese sistema social. Además, se observa la existencia de sociedades contemporáneas que se contraponen al patriarcalismo al poseer organizaciones matrilineales, matrilocales y matriarcales. De esta forma, a pesar de la hegemonía del sistema patriarcal, esta estructura no es única y estática, y su dinamismo es evidenciado por conformaciones sociales existentes en la actualidad.

Children's inequality aversion in intergroup contexts: The role of parents' social dominance orientation, right-wing authoritarianism and moral foundations.

Although children are overall sensitive to inequality and prefer fair allocation of resources, they also often display ingroup favouritism. Inquiring about the factors that can shape the tension between these two driving forces in children, we focused on the role of parents. Extending the limited literature in this field, the present work examined whether individual differences in 3-to 11-year-old White children's (N = 154, 78 boys) evaluations of fair versus pro-ingroup behaviours in an intergroup context vary as a function of both mothers' and fathers' social dominance orientation (SDO), right-wing authoritarianism (RWA), and moral foundations. Parents completed a questionnaire. Children were presented with a scenario in which two ingroup members distributed candies to two other children, one White and one Black, either in an egalitarian way or displaying a clear ingroup favouritism. Afterwards, their attitudes towards the two ingroup members who had distributed the candies were assessed through both an Implicit Association Test and explicit questions. Although children displayed on average an explicit preference for the fair over the pro-ingroup target, this preference did not emerge at the implicit level. Most importantly, both children's explicit and implicit attitudes were related to mothers' SDO, indicating that at increasing level of mothers' SDO children's inequality aversion tended to drop. Overall, these results emphasize the relevance of mothers' support for social hierarchy in relation to the way in which children balance the two competing drives of equality endorsement and pro-ingroup bias.

Effects of social tolerance on stress: hair cortisol concentrations in the tolerant Tonkean macaques (Macaca tonkeana) and the despotic long-tailed macaques (Macaca fascicularis).

Group living is a source of stress and an individuals' social environment has been shown to have a significant effect on its health and well-being. However, little is known about how different social organizations affect the stress levels of their members. Is living in a hierarchical society more or less stressful than living in a more tolerant structure? Here, we assess cortisol concentrations in the hair of two macaque species with radically different dominance styles: the egalitarian Tonkean macaque (Macaca Tonkeana) and the despotic long-tailed macaques (Macaca fascicularis). Hair was sampled in winter and again in late spring in two mixed-sex groups of 22 Tonkean macaques and 9 long-tailed macaques; Hair cortisol concentrations were significantly higher in the egalitarian Tonkean macaques than in the despotic long-tailed macaques, ranging from 161.13 to 938.8 pg/mg (mean ± SD 349.67 ± 126.22) and from 134.46 to 339.86 pg/mg (mean ± SD 231.2 ± 44.24), respectively. There was no difference between male and female cortisol concentrations, but hair cortisol increased with age in males. Dominance rank certainty was lower among female Tonkean macaques compared to long-tailed macaques. Our results suggest that species differences in dominance styles may translate into differences in long-term cortisol concentrations. We suggest that the higher cortisol concentrations in Tonkean macaques could be linked to the instability and lack of predictability and control around social relationships.

LAY SUMMARYBeing part of a social group can be very stressful, depending on the social structure of this group. We found that the more socially tolerant Tonkean macaques exhibited on average higher hair cortisol concentrations than more despotic long-tailed macaques. Males and females exhibited similar concentrations of hair cortisol in both species, but in male Tonkean macaques concentrations increased with age. The finding that overall cortisol levels were higher in the more tolerant species suggests that psychological arousal due to unpredictable social relations and mating competition may be an important driver of cortisol release in this species despite its overall tolerant social organization.

Social Behavior, Ovary Size, and Population of Origin Influence Cuticular Hydrocarbons in the Orchid Bee Euglossa dilemma.

AbstractCuticular hydrocarbons (CHCs) are waxy compounds on the surface of insects that prevent desiccation and frequently serve as chemical signals mediating social and mating behaviors. Although their function in eusocial species has been heavily investigated, little is known about the evolution of CHC-based communication in species with simpler forms of social organization lacking specialized castes. Here we investigate factors shaping CHC variation in the orchid bee Euglossa dilemma, which forms casteless social groups of two to three individuals. We first assess geographic variation, examining CHC profiles of males and females from three populations. We also consider CHC variation in the sister species, Euglossa viridissima, which occurs sympatrically with one population of E. dilemma. Next, we consider variation associated with female behavioral phases, to test the hypothesis that CHCs reflect ovary size and social dominance. We uncover a striking CHC polymorphism in E. dilemma spanning populations. In addition, we identify a separate set of CHCs that correlate with ovary size, social dominance, and expression of genes associated with social behavior, suggesting that CHCs convey reproductive and social information in E. dilemma. Together, our results reveal complex patterns of variation in which a subset of CHCs reflect the social and reproductive status of nestmates.

A Complex Diving-For-Food Task to Investigate Social Organization and Interactions in Rats.

For many species, where status is a vital motivator that can affect health, social hierarchies influence behavior. Social hierarchies that include dominant-submissive relationships are common in both animal and human societies. These relationships can be affected by interactions with others and with their environment, making them difficult to analyze in a controlled study. Rather than a simple dominance hierarchy, this formation has a complicated presentation that allows rats to avoid aggression. Status can be stagnant or mutable, and results in complex societal stratifications. Here we describe a complex diving-for-food task to investigate rodent social hierarchy and behavioral interactions. This animal model may allow us to assess the relationship between a wide range of mental illnesses and social organization, as well as to study the effectiveness of therapy on social dysfunction.
