| Abstract | To keep social cohesiveness, group-living animals have to reach consensus decisions through recruitment processes. This implies that decision-making depends on the behaviours and social relationships of several group members at different stages of movements. We tested these assumptions in a group of fifteen 18-mo-old Charolais heifers (Bos taurus) at pasture, in which two observers continuously videotaped social interactions and group departures after resting periods. These departures were preceded by a phase of preparation characterized by an increase in activity. The number of heifers participating to a movement increased with the number of group members oriented in the direction of the movement before departure. The first moving animal also recruited a higher number of mates when it had a greater number of close neighbours, the first individuals to follow being mainly its preferential partners. Coercive interactions such as pressing behaviours were observed within the 5 min preceding or following departure. After departure, the numbers of walks and restarts of the first two movers were still operative in recruiting others. The frequency of pauses of the first mover was significantly higher when it was not followed, meaning that it adjusted its behaviour to that of other group members. Decision-making was distributed among group members, with any individual being liable to move first. The behaviour of cows and their spatial distribution before departure, at departure and after departure significantly affected the number of participants in the movement, demonstrating that decision-making was time-distributed in the studied cattle group. | ||||

| Title | Influence of Different Individual Traits on Vigilance Behaviour in European Rabbits | Type | Journal Article | ||

| Abstract | An animal's level of vigilance depends on various environmental factors such as predator presence or the proximity of conspecific competitors. In addition, several individual traits may influence vigilance. We investigated the effects of body condition, social rank and the state of pregnancy on individual vigilance (scanning) rates in individually marked European rabbits (Oryctolagus cuniculus) of a field enclosure population. We found lower rates in young rabbits than in adult females, but male and female juveniles did not differ. Vigilance of juveniles was positively correlated with their age-dependent body mass (used as a measure of body condition), i.e. young rabbits with lower body condition scanned less. We suggest that juveniles with low body condition were trading off vigilance against feeding to maximise their growth. In contrast, there was no significant correlation between body mass and vigilance in adult females. Adult females increased scanning rates during late pregnancy, which might constitute a behavioural compensation because of their lower capacity to escape predator attacks. In addition, adult females with low social ranks scanned more than high ranking individuals, likely because of their higher risk of attacks by conspecifics. In summary, our results highlight various individual characteristics that influence vigilance behaviour in European rabbits. | ||||

| Title | Anxiety Level Predicts Post-Conflict Behaviour in Wild Japanese Macaques (Macaca fuscata yakui) | Type | |||

| Abstract | Reconciliation (i.e. the post-conflict exchange of friendly behaviour between former opponents) functions to control for the detrimental effects that aggression may have on social relationships. Studies conducted so far have investigated intra-individual sources of variation in post-conflict behaviour, showing that animals have a stronger increase in anxiety and are more likely to reconcile after conflicts with valuable partners, such as kin. Much less attention has been given to how differences between individuals in emotional profiles affect post-conflict behaviour. Our aim was to analyse whether inter-individual differences in baseline anxiety levels predicted the magnitude of the increase in anxiety following a conflict and the occurrence of reconciliation. We collected data on two groups of wild Japanese macaques (Macaca fuscata yakui). Animals having a higher baseline level of anxiety had a more dramatic anxious response following a conflict while controlling for a series of factors (e.g. relationship quality between opponents). These more anxious animals were also less likely to reconcile than more relaxed individuals. Therefore, more anxious animals face some social costs by being less able to cope with the post-conflict condition. We propose that differences in anxiety levels may be interpreted as tradeoffs between benefits and costs across conditions. For example, more anxious animals, who are less able to reconcile conflicts, might also be less exploratory and thus face a lower risk to eat unknown, poisonous food. | ||||

| Title | Sozialstruktur einer Herde Islandpferde bei Veränderung der Gruppenzusammenstellung | Type | Manuscript | ||
| Year | 2009 | Publication | Abbreviated Journal | ||
| Volume | Issue | Pages | |||

| Abstract | Die Domestikation des Pferdes begann wahrscheinlich etwa 5500 v. Chr. in Südosteuropa. In Mitteleuropa traten circa 3000 v. Chr. die ersten Hauspferde auf. Grundsätzlich wird davon ausgegangen, dass sich die Ansprüche des Pferdes hinsichtlich der Lebensbedingungen, welche sich im Laufe der Evolution über Millionen von Jahren entwickelt haben, in der Obhut des Menschen nicht wesentlich geändert haben. Für Pferde typisch ist das Leben im Sozialverband, der Herde (Zeitler-Feicht 2008). Diese wird auch in den Leitlinien der Sachverständigengruppe tierschutzgerechte Pferdehaltung (10. November 1995) empfohlen, sofern es nicht durch zu häufigen Wechsel im Bestand zu einem Übermaß an Stress und agonistischen Aktionen kommt. Ziel der Arbeit war es, anhand eines nach der Literatur erstellten Ethogramms des Sozialverhaltens des Pferdes, herauszufinden, inwieweit Änderungen der Gruppenstruktur die sozialen Beziehungen beeinflussten. Die Fragestellung bezog sich auf eine Herde in Offenstallhaltung. Um die eventuellen Veränderungen der sozialen Interaktionen zu untersuchen, wurde erst die vorhandene Gruppenstruktur der Herde festgestellt. Danach wurde ein Individuum aus der Herde entfernt und ein anderes dazugestellt. Anschließend wurde die Gesamtgruppe in zwei Untergruppen geteilt und nach einem gewissen Zeitraum erneut zusammengeführt. Dabei wurden jeweils die Interaktionen der Pferde anhand des Ethogramms beobachtet, aufgezeichnet und protokolliert. Untersuchungsgegenstand war eine Herde Islandpferde, die in einer Ausgangsgruppe von 16 Tieren gehalten wurde. Die Beschreibung einer sozialen Ordnung im Allgemeinen und einer Rangordnung im Besonderen wird in vielen Studien ausschließlich auf der Basis der Beobachtung und Bewertung offensiv aggressiver Verhaltenselemente durchgeführt. Aggressives Verhalten muss hingegen im Gegensatz zu Verhaltensweisen, die die Anerkennung des sozialen Status des anderen Pferdes bedeuten, wie Abwenden oder Meiden, nicht notwendigerweise ein Anzeichen von Dominanz über ein anderes Tier bedeuten (Van Hoof u. Wensing 1987, Schilder 1988). Ein weiterer Aspekt dieser Arbeit sollte sein, eine Möglichkeit zu finden, die Sozialstruktur auch auf der Grundlage defensiver und soziopositiver Verhaltenselemente zu definieren. |
