The articles that follow cover research on societies ranging from insects to humans. Variation in measures of fitness (i.e. survival and reproduction) has been linked to various aspects of sociality in humans and animals alike, and variability in individual health and condition has been recognized as a key mediator of these relationships. Viewed from a broad evolutionary perspective, the evolutionary transitions from a solitary lifestyle to group living have resulted in several new health-related costs and benefits of sociality. Social transmission of parasites within groups represents a major cost of group living, but some behavioural mechanisms, such as grooming, have evolved repeatedly to reduce this cost. Group living also has created novel costs in terms of altered susceptibility to infectious and non-infectious disease as a result of the unavoidable physiological consequences of social competition and integration, which are partly alleviated by social buffering in some vertebrates. Here, we define the relevant aspects of sociality, summarize their health-related costs and benefits, and discuss possible fitness measures in different study systems. Given the pervasive effects of social factors on health and fitness, we propose a synthesis of existing conceptual approaches in disease ecology, ecological immunology and behavioural neurosciences by adding sociality as a key factor, with the goal to generate a broader framework for organismal integration of health-related research."],["dc.identifier.doi","10.1098/rstb.2014.0116"],["dc.identifier.gro","3150856"],["dc.identifier.pmid","25870402"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7650"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0962-8436"],["dc.subject","group living; health; fitness; parasites; social transmission; stress"],["dc.title","Sociality and health: impacts of sociality on disease susceptibility and transmission in animal and human societies"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Temporal analyses of behavioural data distinguished agonistic from non-agonistic behaviour and aggressive from submissive behaviour. The ringtailed lemurs employed a diverse repertoire of behavioural elements to communicate agonistic intent. More than 50% of these elements were signals and nearly 50% of signals were submissive. The agonistic repertoire of the redfronted lemurs, by contrast, was relatively unelaborated: less than 40% of agonistic behaviour in this species comprised signals and less than 20% of signals were submissive. These structural differences underlay marked species differences in agonistic interaction and relationship. All pairs of ringtailed lemurs maintained dominance relations resembling those seen in many anthropoid primates: subordinates consistently signalled submissively to dominant partners, often in the absence of aggression. Dominance relations among members of each sex were seasonally unstable and not always transitive (hierarchical) during periods of stability, however. Redfronted lemurs, by contrast, did not maintain dominance relations, failing to respond agonistically to most aggression received (52% of interactions) and responding with aggression on many other occasions (12%). Even applying relaxed criteria, few adult redfronted dyads (14%) showed consistent asymmetries in agonistic relations and several never exhibited any asymmetry. Lacking dominance, E. f rufus relied heavily on alternate behavioural mechanisms to moderate social conflict as frequent and intense as that seen in study groups of ringtailed lemurs. These included a great inclination not to respond agonistically to aggression, a distinctive behavioural proposal to limit or terminate dyadic conflict (Look away), post-conflict reconciliation, and relatively frequent third-party aggression. The existence of such divergent systems of agonistic behaviour in partially sympatric, closely related and generally similar prosimian primates offers important opportunities for comparative study of the ecology, development, and evolution of mammalian social systems. Future research may reveal ecophysiological factors that promote the use of dominance behaviour among like-sexed ringtailed lemurs and show how the relative absence of dominance relates to other major elements of redfronted lemur biology, including 'special relationships' of variable duration between adult males and females."],["dc.identifier.doi","10.1163/156853997x00467"],["dc.identifier.gro","3150919"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7720"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0005-7959"],["dc.title","Divergent Systems of Agonistic Behaviour in Lemurid Primates"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

Many animals restrict their movements to certain areas (home ranges) by alternating visits among several suitable sites. The dynamics of these recursive movements are assumed to be primarily driven by food availability and predation risk. In contrast, environmental parasite pressures have rarely been considered as possible drivers of animals' ranging patterns. In this article, we present evidence that environmentally transmitted gastrointestinal parasites may shape recursive movement patterns of a group of free-ranging mandrills, Mandrillus sphinx. These rainforest-dwelling primates returned less frequently and after longer time lags to sites, including sleeping sites, they had contaminated than to sites with low contamination levels. This pattern was especially pronounced during the dry season, when contamination risk was highest. In contrast, rainfall shortened the time between visits, consistent with the hypothesis that rainfall may wash away parasites, allowing a more rapid return to previously used sites. Although resource distribution and predator threat could not be ruled out in this study, we suggest that the risk of acquiring environmentally transmitted parasites is possibly another factor influencing animal ranging patterns as well as habitat selection or species distribution. Consequently, parasites and their distribution in the environment, as well as the possible antiparasite strategy we document here, should be targets for future research on animal movement."],["dc.identifier.doi","10.1016/j.anbehav.2017.10.013"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/12110"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.title","Gastrointestinal parasitism and recursive movements in free-ranging mandrills"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

However, empirical studies on indirect transmission within wildlife populations are scarce. We investigated whether asynchronous overnight refuge sharing among neighboring sleepy lizards, Tiliqua rugosa, facilitates indirect transmission of its ectoparasitic tick, Amblyomma limbatum. We fitted 18 neighboring lizards with GPS recorders, observed their overnight refuge use each night over 3 months, and counted their ticks every fortnight. We constructed a transmission network to estimate the cross-infection risk based on asynchronous refuge sharing frequencies among all lizards and the life history traits of the tick. Although self-infection was possible, the network provided a powerful predictor of measured tick loads. Highly connected lizards that frequently used their neighbors' refuges were characterized by higher tick loads. Thus, indirect contact had a major influence on transmission pathways and parasite loads. Furthermore, lizards that used many different refuges had lower cross- and self-infection risks and lower tick loads than individuals that used relatively fewer refuges. Increasing the number of refuges used by a lizard may be an important defense mechanism against ectoparasite transmission in this species. Our study provides important empirical data to further understand how indirectly transmitted parasites move through host populations and influence individual parasite loads."],["dc.identifier.doi","10.1007/s00265-010-0964-6"],["dc.identifier.gro","3150912"],["dc.identifier.pmid","20802788"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/4975"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7712"],["dc.language.iso","zh"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.issn","0340-5443"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject","Ectoparasites; Indirect transmission; Infection risk; Lizards; Network; Ticks"],["dc.title","Refuge sharing network predicts ectoparasite load in a lizard"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

An unusual prenatal endocrine environment has been proposed to proximately underlie the development of these traits in hyenas. To examine whether female dominance and genital masculinization are similarly enhanced by the prenatal environment in lemurid primates, we measured androgen and estrogen excretion in pregnant wild redfronted lemurs (Eulemur fulvus rufus). Our results showed that estrogen levels during the second phase of gestation were much higher in females carrying a male fetus than in female-carrying mothers. This may indicate the onset of testicular activity in male fetuses, because androgens of fetal origin are aromatized to maternal estrogens. Levels of androgen excretion were similar in all mothers regardless of the fetus' sex, which may suggest that androgen-independent mechanisms also contribute to female masculinization. The much higher androgen/estrogen ratio in female-carrying mothers indicates that relative, rather than absolute, prenatal steroid concentrations may play a role in female masculinization."],["dc.identifier.doi","10.1007/s00114-003-0404-9"],["dc.identifier.pmid","12649757"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/10029"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.title","Intersexual dominance, masculinized genitals and prenatal steroids: comparative data from lemurid primates"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

The main aim of our study was to identify the relative importance of, and interactions among, potential determinants of contrasting male reproductive tactics, and to determine their consequences for male reproductive success in a small solitary nocturnal Malagasy primate, the gray mouse lemur (Microcebus murinus). We studied their mating behavior over three consecutive annual mating seasons. In addition, we determined the genetic relationships among more than 300 study animals to quantify the reproductive success of individual males. We found that, with a given relatively low overall monopolization potential, successful male mouse lemurs roamed extensively in search of mates, had superior finding ability and mated as early as possible. However, contest competition was important too, as temporary monopolization was also possible. Males exhibited different mating tactics, and heavier males had a higher reproductive success, although most litters had mixed paternities. Switching between tactics depended on short-term local variation in monopolization potential determined by a pronounced dynamic in fertilization probability, number of alternative mating opportunities, and the operational sex ratio. This study also revealed that the dynamics of these determinants, as well as the mutual interactions between them, necessitate a detailed knowledge of the mating behavior of a species to infer the impact of determinants of alternative mating tactics."],["dc.identifier.doi","10.1007/s00265-004-0826-1"],["dc.identifier.gro","3150878"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7673"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0340-5443"],["dc.title","Sex in the dark: determinants and consequences of mixed male mating tactics in Microcebus murinus, a small solitary nocturnal primate"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

Untersuchungen der frühen Entwicklung des Verhaltens haben eine lange Geschichte, die bis in die klassische Ethologie zurück reicht. Während der frühen Individualentwicklung beginnen frisch geschlüpfte oder neugeborene Jungtiere durch ihr Verhalten mit ihrer belebten und unbelebten Umwelt zu interagieren. Vom ersten Moment an werden die Fähigkeiten, ihre grundlegenden Körperfunktionen zu stabilisieren, für das energetisch kostspielige Wachstum ausreichend Nahrung zu gewinnen sowie nicht gefressen zu werden, von natürlicher Selektion bewertet. Verhaltensweisen, die diese Fähigkeiten beeinflussen, sollten daher weitestgehend abrufbereit vorliegen, also einer genetischen Kontrolle unterliegen (→ Kapitel 11.1). Andere Verhaltensweisen sind artspezifisch, treten nur bei einem Geschlecht oder nur zu bestimmten Phasen der Individualentwicklung auf, was auf einen genetischen Einfluss hindeutet. Künstliche Selektion durch den Menschen kann ebenfalls Hinweise auf die genetische Kontrolle von Verhaltensweisen liefern. Bei der Entwicklung und Integration eines Organismus spielen Hormone eine wichtige integrative Rolle (→ Kapitel 11.2). Zudem haben Hormone auch eine zentrale Rolle bei der Anpassung an sich verändernde reproduktive, ökologische und soziale Bedingungen. Die Entwicklung eines Individuums sollte also über seine komplette Lebensspanne betrachtet werden und nicht nur auf die frühe Individualentwicklung fokussieren. Mit zunehmendem Alter nimmt auch die individuelle Erfahrung zu, so dass es im Laufe der Individualentwicklung zu Modifikation und Anpassung des Verhaltens durch verschiedene Lernprozesse kommt (→ Kapitel 11.3). Außerdem haben neuere Studien gezeigt, dass durch Umwelteinflüsse erworbene Modifikationen des Erbguts über die gesamte Lebensspanne wirken und sogar an die eigenen Nachkommen weitergegeben werden kann. All diese Prozesse werfen grundlegende Fragen über die Kontrolle des Verhaltens auf, die zunehmend interdisziplinär von Genetikern, Neurobiologen und Verhaltensforschern bearbeitet werden (Robinson 1999)."],["dc.description.edition","3., korrigierte und ergänzte Auflage"],["dc.identifier.doi","10.1007/978-3-642-20653-5_11"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/13197"],["dc.language.iso","de"],["dc.notes.status","final"],["dc.publisher","Springer"],["dc.relation.crisseries","Springer-Lehrbuch"],["dc.relation.isbn","978-3-642-20652-8"],["dc.relation.isbn","978-3-642-20653-5"],["dc.relation.ispartof","Verhaltensbiologie"],["dc.relation.ispartofseries","Springer-Lehrbuch"],["dc.title","Entwicklung und Kontrolle des Verhaltens"],["dc.type","book_chapter"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]
