| Title | Die Bedeutung des Leerkauens bei Pferden aus Sicht der Physiologie und der Ethologie | Type | Manuscript | ||
| Year | 2012 | Publication | Abbreviated Journal | ||

| Abstract | Der Umgang mit Pferden erfreut sich immer größerer Beliebtheit. Aufgrund des Verhaltens können Rückschlüsse auf die Befindlichkeiten der Tiere gezogen werden (TSCHANZ et al. 1997a). Je mehr wir über das Verhalten der Tiere wissen, desto besser können wir in der Haltung, Ausbildung und Nutzung der Pferde dazu beitragen, die Lebensbedingungen zu verbessern und den Ansprüchen der Pferde gerechter zu werden. Bei der Ausbildung von Pferden kommen u.a. aus Amerika neue Einflüsse auf Ausbildungsmethoden zu uns. Es wird dabei immer wieder ein „Kauen“ der Pferde während des Trainings beschrieben, doch gibt es keine wissenschaftlichen ntersuchungen darüber. Eine Kaubewegung des Pferdes außerhalb der Futteraufnahme wird als „Leerkauen“ definiert. Es ist eine „horizontale Bewegung“ des Unterkiefers gegen den Oberkiefer zu beobachten, vergleichbar mit der Mahlbewegung (Abbildung 1). Häufig ist während des Leerkauens eine Anspannung des oberflächlichen Kaumuskels vom unteren Unterkieferrand aus in Richtung Jochbogen/Crista facialis zu erkennen. Eine Sonderform des Leerkauens stellt die sogenannte Unterlegenheitsgebärde (UG) dar (ZEEB 1959b). Es handelt es sich um eine „vertikale Bewegung“ der Unter- und Oberkiefer voneinander weg und aufeinander zu (Abbildung 2). Ihre Funktion ist die Beschwichtigung. Unter dem Begriff Leerkauen wird in dieser Dissertation immer die horizontale Mahlbewegung verstanden. |

| Abstract | <p>Relationships we have with our friends, family, or colleagues influence our personal decisions, as well as decisions we make together with others. As in human beings, despotism and egalitarian societies seem to also exist in animals. While studies have shown that social networks constrain many phenomena from amoebae to primates, we still do not know how consensus emerges from the properties of social networks in many biological systems. We created artificial social networks that represent the continuum from centralized to decentralized organization and used an agent-based model to make predictions about the patterns of consensus and collective movements we observed according to the social network. These theoretical results showed that different social networks and especially contrasted ones – star network vs. equal network – led to totally different patterns. Our model showed that, by moving from a centralized network to a decentralized one, the central individual seemed to lose its leadership in the collective movement's decisions. We, therefore, showed a link between the type of social network and the resulting consensus. By comparing our theoretical data with data on five groups of primates, we confirmed that this relationship between social network and consensus also appears to exist in animal societies.</p> | ||||

| Abstract | In contrast to the great similarity in behaviour and ecology of the 6 extant Equid species, 2 distinct types of social organisation have evolved, and both are adapted to life in semi-arid to arid regions where environmental conditions force them to migrate seasonally or opportunistically. The ranges of the various species overlap: Mountain Zebra Equus zebra and Plains Zebra E. quagga in South Africa and Namibia, Plains Zebra and Grevy's Zebra E. grevyi in Kenya and Ethiopia, Grevy's Zebra and African Wild Ass E. africanus in Ethiopia, Asiatic Wild Ass E. hemionus and Przewalski Horse E. przewalski in Mongolia and China. Although, in the overlap zones, individuals of the different species are using the same resources like water and grazing next to each other, they rarely make closer contacts. . In the type 1 species, Horse, Plains Zebra and Mountain Zebra, the adults live in non-territorial, stable, one-male families and as single bachelors and in bachelor groups. Family stallions have the exclusive mating rights with the mares in their harems. These consist of up to 6 unrelated mares plus their offspring, totalling up to 20 members. Mares stay in their harem until death. Stallions' tenure is from age 5-6 years, i.e. when they succeed in controlling a harem, for close to life time, but are replaced when dead or incapacitated. Harems are stable even in the absence of a stallion, indicating voluntary membership. Adolescent mares leave their parental families to become members of another harem. In Plains Zebra the adolescent mares are abducted, during an oestrus, by suitors who fight the defending family stallion/father. Successful stallions are bachelors who start a family, or family stallions enlarging their harem. Young stallions leave their parental families voluntarily at age 2-3 years and join bachelor stallion groups from where the family stallions are recruited. An individualised dominance hierarchy excists with the stallion in the alpha position. It is based on individual knowledge and recognition of the members. In the type 2 species Grevy's Zebra, African Wild Ass and Asiatic Wild Ass adult stallions monopolise territories in which they have the exclusive mating rights. Stallions are tolerant of any conspecifics entering their territory. Bachelor stallions behave subordinately – or fight for the possession of the territory which is a prerequisite for reproduction. Mares join up to form anonymous and unstable groups or herds. The only stable unit is of a mare and her offspring. In Grevy's Zebra mares with foal join preferentially conspecifics of the same soial status, as do mares without foal. Matings take place inside the territory. There is no lasting relationship of the mare with a particular stallion, and the mare may be mated by any stallion whose territory she is visiting. Territories measure up to 10 or more square kilometres, and tenure is for several years. Grevy Zebra territorial owners leave their territories for a few hours to visit a water hole, or for months when grazing and water conditions are below requirements, and re-occupy it upon return, unchallenged. |

| Abstract | Verhalten und Ökologie der 6 rezenten Equiden sind in vieler Hinsicht identisch, jedoch in der Sozialen Organisation haben 2 deutliche verschiedene Formen evoluiert, die beide an das Leben in den semi-ariden und ariden Lebensräumen angepasst sind, wo sie zu säsonalen oder opportunistischen Wanderungen gezwungen sind. Die Verbreitungsgebiete der verschiedenen Arten überlappen, in Südafrika und Namibia von Bergzebra Equus zebra und Steppenzebra E. quagga, in Kenya und Äthiopien von Steppenzebra und Grevy-Zebra E. grevyi, in Äthipien und Somalia von Grevy-Zebra und Afrikanischem Wildesel E. africanus, in China und der Mongolei Asiatischer Wildesel E. hemionus und Przewalski-Pferd E. przewalskii. Obwohl die Vertreter der verschiedenen Arten in den Überschneidungsgebieten die gleichen Ressourcen wie Wasser und Weide nutzen, nehmen sie kaum Kontakt zueinander auf. Die Vertreter von Typ 1, Steppenzebra Equus quagga, Bergzebra E..zebra, Pferd E przewalskii, leben in nicht-territorialen , dauerhaften 1- Hengst- Familien, in Hengstgruppen und als Einzelgänger.. Die Familienhengste haben die alleinigen Paarungsrechte mit den Stuten in ihrem Harem. Dieser besteht aus bis zu ca. 6 nicht-verwandten Stuten nebst ihren Nachkommen und kann bis 20 Mitglieder haben. Stuten bleiben bis zu ihrem Tod im Harem..Hengste können mit 5-6 Jahren einen Harem erobern oder gründen, können gleichfalls bis zum Tod die Familie begleiten, werden aber meist vorher von einem anderen Hengst ersetzt. Harems sind auch ohne Hengst stabil, ein Hinweis, dass die Stuten freiwilling im Harem sind und bleiben.. Junge Stuten verlassen ihre elterliche Familie und schliessen sich einem anderen Harem an..Beim Steppenzebra werden die Jungstuten während eines Östrus (Rosse) von Bewerbern entführt, gegen den Widerstand des Familenhengstes = Vaters. Bewerber sind Junggesellen, die so eine Familie gründen, und Familienhengste, die so ihren Harem vergrössern. Junghengste verlassen mit 2-3Jahren ihre elterliche Familie und schliessen sich Jungesellengruppen an, aus denen sich die Familenhengste rekrutieren. In der Gruppe besteht eine Rangordnung mit dem Henst in der alpha-Position. Sie beruht aud individuellem Kennen und Erkennen der Mitglieder. Bei Typ 2, Grevy-Zebra, Afrikanischer und Asiatischer Wildesel, monopolisieren Hengste über Jahre Territorien von 10 und mehr km2 , in denen sie die alleinigen Paarungsrechte haben. Territoriale Hengste tolerieren Artgenossen, auch erwachsene Hengste, soweit diese sich unterlegen verhalten. Oder sie stellen sich zum Kampf um den Besitz des Territoriums, eine Vorbedingung für die Fortpflanzung. Stuten im Östrus können von mehreren Hengsten begattet werden, wenn sie sich in deren Territorien aufhalten bzw diese durchwandern. Stuten und Fohlen und nicht-territoriale Hengste schliessen sich zu anonymen instabilen Gruppen oder Herden zusammen. Feste dauerhafte Bindungen bestehen nur zwischen Stute und Fohlen. Hengste verlassen ihr Territorium für Stunden, Tage, im Extrem auch Monate, um zu Wasserstellen oder Weidegründen zu ziehen, sind aber bei Rückkehr wieder unangefochtene Besitzer. |
