Influence of Paddock Size on Social Relationships in Domestic Horses
Contributor(s):: Majecka, Katarzyna, Klawe, Aneta
The aim of this study was to explore whether the size of paddocks affected social interactions within a group of horses. Furthermore, the effects of the gender composition in groups on social behavior were investigated. The research was done in a horse-riding center. A total of 78 horses and...
Testing the Roles of Intergroup Anxiety and Inclusion of Animals in the Self as Mechanisms that Underpin the “Pets as Ambassadors” Effect
Contributor(s):: Auger, Béatrice, Amiot, Catherine E.
It has been suggested that pets provide the opportunity for humans to develop more positive attitudes and relationships toward a wider range of animal types—including toward non-pet animals—this is called the “pets as ambassadors” hypothesis. In this study, we build both on research conducted on...
A Companion Dog Increases Prosocial Behavior in Work Groups
Contributor(s):: Colarelli, Stephen M., McDonald, Amanda M., Christensen, Matthew S., Honts, Christopher
Although organizations use a variety of interventions to improve group functioning, getting people to work effectively with each other remains challenging. Because the presence of a dog has been shown to have positive effects on mood and dyadic interaction, we expected that the presence of a...
Group suckling cohesion as a prelude to the formation of teat order in piglets
Contributor(s):: Skok, Janko, Škorjanc, Dejan
During the lactation period, piglets experience intense social interactions with their littermates until they establish a reliable teat order on the mother's udder. Here, we examined group suckling cohesion in piglet littermates, an order mechanism that refer to the maintenance of significantly...
Flocking for food or flockmates?
Contributor(s):: Asher, Lucy, Collins, Lisa M., Pfeiffer, Dirk U., Nicol, Christine J.
Animals in groups behave cohesively, even when those animals are domesticated and are housed in limited environments. But how is such group cohesion maintained? Do animals move in an independent manner, according to their own motivations, or in a social manner, with respect to the movements of...
Social housing of surplus males of Javan langurs (Trachypithecus auratus): Compatibility of intact and castrated males in different social settings
Contributor(s):: Dröscher, Iris, Waitt, Corri D.
Javan langurs (Trachypithecus auratus) naturally form social groups containing typically only one adult male. However, this social system is problematic with regard to captive management, as it can lead to the production of surplus males. The study assessed if castration is a feasible strategy to...
Simulations of the social organization of large schools of fish whose perception is obstructed
Contributor(s):: Kunz, Hanspeter, Hemelrijk, Charlotte K.
Individual-based models have shown that simple interactions among moving individuals (repulsion, attraction and alignment) result in travelling schools that resemble those of real fish. In most models individuals interact with all neighbours within sensory range which usually includes almost all...
Sex ratio, conflict dynamics, and wounding in rhesus macaques (Macaca mulatta)
Contributor(s):: Beisner, B. A., Jackson, M. E., Cameron, A., McCowan, B.
Rhesus macaques, like many other primates, live in stable, multi-male multi-female groups in which adult females typically outnumber adult males. The number of males in multi-male/multi-female groups is most commonly discussed in terms of mate competition, where the sex ratio is a function of an...
Preliminary analysis of an adjective-based dog personality questionnaire developed to measure some aspects of personality in the domestic dog (Canis familiaris)
Contributor(s):: Mirkó, Erika, Kubinyi, Enikő, Gácsi, Márta, Miklósi, Ádám
In this paper we present a novel adjective-based dog personality questionnaire, which was successfully implemented to characterise the behaviour of individual dogs. The scales obtained by Principal Component Analysis (Stranger-directed Sociability, Activity, Aggressiveness and Trainability)...
Identifying potential risk situations for humans when removing horses from groups
Contributor(s):: Hartmann, Elke, Søndergaard, Eva, Keeling, Linda J.
Removing a horse from its social group may be considered risky, both for the handler and the horse, because other horses can interfere in the catching process. The main aim of this study was to identify where and when these risk situations occur while removing a horse from its group. A potential...
How can social network analysis contribute to social behavior research in applied ethology?
Contributor(s):: Makagon, Maja M., McCowan, Brenda, Mench, Joy A.
Social network analysis is increasingly used by behavioral ecologists and primatologists to describe the patterns and quality of interactions among individuals. We provide an overview of this methodology, with examples illustrating how it can be used to study social behavior in applied contexts....
Dry sows in dynamic groups: An investigation of social behaviour when introducing new sows
Contributor(s):: Krauss, Verena, Hoy, Steffen
In the investigation 22 groups of sows (with a total number of 73 sows, being partially observed repeatedly) were consecutively observed for 96h with the aid of video technology after the introduction of 5 new sows into a group of 10 resident sows, thus creating a dynamic group of 15 animals. The...
Are personality traits consistent in fish?—The influence of social context
Contributor(s):: Castanheira, Maria Filipa, Cerqueira, Marco, Millot, Sandie, Gonçalves, Rui A., Oliveira, Catarina C. V., Conceição, Luís E. C., Martins, Catarina I. M.
Individual differences in behavioural and physiological responses to challenges are progressively accepted as adaptive variation and reveal a strong degree of evolutionary conservation throughout the vertebrate taxa. Previous studies in gilthead seabream (Sparus aurata) suggested that individual...
Effects of group housing system, pen floor type, and lactation management on performance and behaviour in rabbit does
Contributor(s):: Zomeño, Cristina, Birolo, Marco, Gratta, Francesco, Zuffellato, Andrea, Xiccato, Gerolamo, Trocino, Angela
This work aimed at evaluating the effects of housing system, pen floor type, and lactation management on rabbit doe and kit performance throughout a reproductive cycle, including categorization of aggressiveness and injuries. Forty multiparous pregnant does were assigned to six experimental...
Adult-adult social play in captive chimpanzees: Is it indicative of positive animal welfare?
Contributor(s):: Yamanashi, Yumi, Nogami, Etsuko, Teramoto, Migaku, Morimura, Naruki, Hirata, Satoshi
Play is sometimes considered as an indicator of positive animal welfare. However, it is not yet sufficiently understood whether or not social play among adults can be considered as such an indicator because it is rare in adult animals. This study investigates the factors that influence social...
Female social behaviour during three male introductions in captive groups of rhesus macaques
Contributor(s):: Rox, Astrid, de Vries, Han, Louwerse, Annet L., Sterck, Elisabeth H. M.
Introductions of new males into captive primate groups are often necessary to prevent inbreeding, but also bear high social risks. To minimize these risks, it is crucial to understand the social behaviour accompanying male introductions. While the behaviour of new males is generally understood,...
