  Title Whom to Groom and for What? Patterns of Grooming in Female Barbary Macaques (Macaca sylvanus) Type Journal Article
  Year 2015 Publication Plos One Abbreviated Journal Plos One  
  Volume 10 Issue 2 Pages (down) e0117298  
  Keywords  
  Abstract Grooming is one of the most conspicuous social interactions among nonhuman primates. The selection of grooming partners can provide important clues about factors relevant for the distribution of grooming within a social group. We analyzed grooming behavior among 17 semi-free ranging female Barbary macaques (Macaca sylvanus). We tested whether grooming is related to kinship, rank and friendship. Furthermore, we tested whether grooming is reciprocated or exchanged for rank related benefits (i.e. lower aggression and increased tolerance whilst feeding). We found that in general grooming was reciprocally exchanged, directed up the hierarchy and at the same time affected by friendship and kinship. Grooming was more frequent among individuals with higher friendship values as well as amongst related individuals. We also divided our data set on the basis of rank difference and tested if different power asymmetries between individuals affected the tendency to exchange grooming for rank related benefits and grooming reciprocation. In support of our initial hypothesis our results show that the reciprocation of grooming was a significant predictor of grooming interactions between individuals of similar rank, but not between those individuals more distantly separated in the social hierarchy. However, we did not find any evidence for grooming being exchanged for rank related benefits in either data set. Our results, together with previously published studies, illustrate the behavioral flexibility of macaques. It is clear that multiple studies of the same species are necessary to gather the data required for the solid comparative studies needed to shed light on patterns of grooming behavior in primates.

  Title Robustness mechanisms in primate societies: a perturbation study Type Journal Article
  Year 2005 Publication Proceedings. Biological sciences / The Royal Society Abbreviated Journal Proc Biol Sci  
  Volume 272 Issue 1568 Pages (down) 1091-1099  
  Keywords Aggression/physiology; Animals; *Conflict (Psychology); Female; *Hierarchy, Social; Macaca nemestrina/*physiology; Male; *Models, Theoretical; Observation; *Social Behavior  
  Abstract Conflict management mechanisms have a direct, critical effect on system robustness because they mitigate conflict intensity and help repair damaged relationships. However, robustness mechanisms can also have indirect effects on system integrity by facilitating interactions among components. We explore the indirect role that conflict management mechanisms play in the maintenance of social system robustness, using a perturbation technique to 'knockout' components responsible for effective conflict management. We explore the effects of knockout on pigtailed macaque (Macaca nemestrina) social organization, using a captive group of 84 individuals. This system is ideal in addressing this question because there is heterogeneity in performance of conflict management. Consequently, conflict managers can be easily removed without disrupting other control structures. We find that powerful conflict managers are essential in maintaining social order for the benefit of all members of society. We show that knockout of components responsible for conflict management results in system destabilization by significantly increasing mean levels of conflict and aggression, decreasing socio-positive interaction and decreasing the operation of repair mechanisms.

  Title Brightness discrimination and neutral point Type Journal Article
  Year 2004 Publication Canadian Journal of Zoology Abbreviated Journal Can. J. Zool  
  Volume 82 Issue 4 Pages (down) 660-670  
  Keywords  
  Abstract Abstract: Equine brightness discrimination ability and color discrimination were measured using a two-choice discrimination

task. Two Haflinger horses (Equus caballus L., 1758) were trained to discriminate 30 different shades of grey

varying from low to high relative brightness. Their ability to distinguish shades of grey was poor, with calculated

Weber fractions of 0.42 and 0.45. In addition, a “neutral point” test to determine the dimensionality of color vision

was carried out. Three hues of blue-green were tested versus a range of grey targets with brightnesses similar to those

of the blue-green targets. A neutral point was found at about 480 nm. Thus, we can conclude that horses possess

dichromatic color vision.

  Title Policing stabilizes construction of social niches in primates Type Journal Article
  Year 2006 Publication Nature Abbreviated Journal Nature  
  Volume 439 Issue 7075 Pages (down) 426-429  
  Keywords Animals; Conflict (Psychology); Female; Macaca nemestrina/*physiology/*psychology; Male; Models, Biological; *Social Behavior  
  Abstract All organisms interact with their environment, and in doing so shape it, modifying resource availability. Termed niche construction, this process has been studied primarily at the ecological level with an emphasis on the consequences of construction across generations. We focus on the behavioural process of construction within a single generation, identifying the role a robustness mechanism--conflict management--has in promoting interactions that build social resource networks or social niches. Using 'knockout' experiments on a large, captive group of pigtailed macaques (Macaca nemestrina), we show that a policing function, performed infrequently by a small subset of individuals, significantly contributes to maintaining stable resource networks in the face of chronic perturbations that arise through conflict. When policing is absent, social niches destabilize, with group members building smaller, less diverse, and less integrated grooming, play, proximity and contact-sitting networks. Instability is quantified in terms of reduced mean degree, increased clustering, reduced reach, and increased assortativity. Policing not only controls conflict, we find it significantly influences the structure of networks that constitute essential social resources in gregarious primate societies. The structure of such networks plays a critical role in infant survivorship, emergence and spread of cooperative behaviour, social learning and cultural traditions.

  Title Häufigkeiten von Erkrankungen und Verletzungen in der Schweizer Pferdepopulation Type Journal Article
  Year 2008 Publication Schweizer Archiv für Tierheilkunde Abbreviated Journal  
  Volume 150 Issue 8 Pages (down) 399-408  
  Keywords  
  Abstract Bei einer für die Schweiz repräsentativ und zufällig ausgewählten Stichprobe von 2912 Pferden und Ponys wurden mittels Fragebogen Daten zum aktuellen Gesundheitszustand und zum Auftreten von Erkrankungen und Verletzungen während der vergangenen 12 Monate erfasst. 718 Pferde (24.7%) wurden im Erfassungszeitraum wegen 897 gesundheitlichen Problemen einem Tierarzt vorgestellt. Orthopädische und traumatische Fälle machten den grössten Anteil aus (41.5%), gefolgt von Erkrankungen des Gastrointestinal- (27.1%) und des Respirationstrakts (14.0%). Die Hälfte der Lahmheiten entstand als unmittelbare Folge einer Verletzung. Die Verletzungen waren assoziiert mit Weidegang/Auslauf (38.1%), Schläge/Bissen durch Artgenossen (21.6%), Stall (7.8%), Gelände (13.4%), Training (3.5%), Wettkampf (3.5%), Transport (3.0%) oder mit anderen Umständen (9.1%). In 26.5% der Kolikfälle wurde im Monat vor der Erkrankung Futterumstellung vorgenommen. Bei den Atmungserkrankungen wurde in 13.8% die gleiche Krankheit auch bei anderen Pferden im Stall diagnostiziert. Bei 8.1% aller Fälle erfolgte eine Operation, 6.7% waren mit einem mehrtägigem Klinikaufenthalt verbunden. Bei 25.6% aller tiermedizinisch diagnostizierten Fälle wurden ergänzend oder ausschliesslich komplementärmedizinische Therapiemethoden eingesetzt.

  Title Dyadic relationships and operational performance of male and female owners and their male dogs Type Journal Article
  Year 2009 Publication Behavioural Processes Abbreviated Journal Behav. Process.  
  Volume 81 Issue 3 Pages (down) 383-391  
  Keywords Dyadic interactions; Human-animal companions; Human-animal relationships; Human-dog dyads; Personality; Social stress  
  Abstract In the paper we investigate how owner personality, attitude and gender influence dog behavior, dyadic practical functionality and the level of dog salivary cortisol. In three meetings, 12 female and 10 male owners of male dogs answered questionnaires including the Neo-FFI human personality inventory. Their dyadic behavior was video-taped in a number of test situations, and saliva samples were collected. Owners who scored highly in neuroticism (Neo-FFI dimension one) viewed their dogs as social supporters and spent much time with them. Their dogs had low baseline cortisol levels, but such dyads were less successful in the operational task. Owners who scored highly in extroversion (Neo-FFI dimension two) appreciated shared activities with their dogs which had relatively high baseline cortisol values. Dogs that had female owners were less sociable-active (dog personality axis 1) than dogs that had male owners. Therefore, it appears that owner gender and personality influences dyadic interaction style, dog behavior and dyadic practical functionality.

  Title Domestic dogs (Canis familiaris) are sensitive to the attentional state of humans Type Journal Article
  Year 2003 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol  
  Volume 117 Issue 3 Pages (down) 257-263  
  Keywords Animals; *Appetitive Behavior; *Attention; *Bonding, Human-Pet; *Concept Formation; Cues; Dogs/*psychology; Female; Humans; *Inhibition (Psychology); Male; Nonverbal Communication  
  Abstract Twelve domestic dogs (Canis familiaris) were given a series of trials in which they were forbidden to take a piece of visible food. In some trials, the human continued to look at the dog throughout the trial (control condition), whereas in others, the human (a) left the room, (b) turned her back, (c) engaged in a distracting activity, or (d) closed her eyes. Dogs behaved in clearly different ways in most of the conditions in which the human did not watch them compared with the control condition, in which she did. In particular, when the human looked at them, dogs retrieved less food, approached it in a more indirect way, and sat (as opposed to laid down) more often than in the other conditions. Results are discussed in terms of domestic dogs' social-cognitive skills and their unique evolutionary and ontogenetic histories.

  Abstract Mit der zunehmenden Bedeutung der Gruppenhaltung von Pferden ist die Tierärzteschaft gefordert mitzuhelfen, das Verletzungsrisiko in

Gruppenhaltungssystemen zu verringern. Dem Vermeiden von Schlag- und Bissverletzungen kommt hierbei eine zentrale Bedeutung zu. Präventive

Maßnahmen konzentrieren sich im Wesentlichen auf die Gruppenzusammensetzung und Eingliederung neuer Pferde sowie auf die

Gestaltung der Haltungssysteme. Die Raumaufteilung und die Fütterungstechnik müssen equidentypisches Verhalten (Lokomotion, langandauernde

Futteraufnahme und schadensfreie soziale Interaktionen) erlauben. Es gilt, Kenntnisse über Zusammenhänge zwischen Haltung,

Fütterung, Nutzung, Verhalten und Gesundheit an Pferdehalter und Stallbaufirmen weiterzugeben.

[Although group housing of horses has become common practice, the risk of equine injury is substantial. The veterinary community is challenged

to reduce this risk, particularly with regard to injuries caused by kicking and biting. Preventive measures should focus on the disposition

of horses within the group, the introduction of new horses to the group and the design of the housing facility. Feeding methods as

well as the structure of the environment should meet the physiological requirements for horses; there should be adequate space for exercise,

extended foraging and the possibility of benign social interactions. Veterinarians need to educate horse owners and builders of equine

facilities about the husbandry, feeding, use, behaviour and health of horses.]

  Title Gender, age and seasonal effects on IgA deficiency: a study of 7293 Caucasians Type Journal Article
  Year 2004 Publication European Journal of Clinical Investigation Abbreviated Journal  
  Volume 34 Issue 3 Pages (down) 224-228  
  Keywords Age- and gender-related variability; immunoglobulin A; seasonal variability; serum IgA deficiency  
  Abstract Background The frequency of serum IgA deficiency (SIgAD) differs between populations. We examined the prevalence of SIgAD in healthy Caucasians. Materials and methods Serum immunoglobulin A (SIgA) was measured in 7293 volunteers (2264 women, 5029 men) aged 30 ± 14·2 years (mean ± SD; range: 12–66). Serum immunoglobulin A and subnormal SIgA levels were defined by a SIgA level < 0·07 g L-1, and between 0·07 and 0·7 g L-1, respectively. Means were compared by analysis of variance (anova) and analysis of covariance (ancova); frequencies by the χ2 test. Results Fifteen subjects (0·21%; one woman, 14 men) had SIgAD. Subnormal SIgA levels were found in 155 persons (2·13%): 21 females (0·93% of the females) and 134 males (2·66% of the males; difference: 1·74%; 95% CI: 1·12–2·33%; P < 0·001). Males were more likely to have subnormal SIgA levels or SIgAD (odds ratio 3·09, 95% CI: 1·97–4·85). The prevalence of SIgAD and subnormal SIgA was lowest in winter (χ2 = 14·8; P = 0·002; 3 d.f.; and χ2 = 43·2; P < 0·001; 3 d.f., respectively). Serum immunoglobulin A concentrations were significantly higher during winter. Serum immunoglobulin A levels increased with age on average by 0·2 ± 0·06 g L-1 per decade of life (P < 0·001). Taking into account the influence of age, SIgA concentration was lower in females as compared with males. Conclusion The prevalence of SIgAD and subnormal SIgA levels is increased in males. There exists a significant influence of gender, age and seasons on SIgA levels.
