Abstract |
A good horse-rider ‘match’ is important in the context of equine welfare. To quantify the influence of repetition and horse-rider matching on the stress of horses encountering challenging objects, 16 Warmblood horses were ridden in a test-setting on three occasions. On each occasion the horse was ridden by a different rider and was challenged by three objects (A–C). Heart rate (HR), heart rate variability (HRV) of horse and rider, and behaviour score (BS) of the horse were obtained for each object and as a total for each test. The horse-rider interaction was evaluated with each combination and assessed as ‘matching’ or ‘mismatching’, and the horses were categorised as ‘compliant’, ‘partly-compliant’ or ‘non-compliant’. Horses exhibited a decreased HR (P = 0.015) and a decreased BS (P = 0.004) within and across different tests. ‘Matching’ horse-rider combinations exhibited less stress as indicated by reduced HR (‘match’ 69 ± 10 vs. ‘mismatch’ 72 ± 9, P = 0.001) and BS (‘match’ 1.9 ± 1.1 vs. ‘mismatch’ 3.8 ± 1.4, P = 0.017) of the horse. ‘Compliant’ (68 ± 8, P < 0.001) and ‘partly-compliant’ (71 ± 9, P = 0.002) horses had significantly lower HR than ‘non-compliant’ (75 ± 9) animals. The findings of the study indicate that HR and BS measurements support a subjective ‘match’ diagnosis and HR measurement may be a valuable tool in assessing horse compliance. |

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 |
As a part of our research on the evolution of social learning in insects, we examined socially influenced behaviour and social learning in desert locust (Schistocerca gregaria) nymphs and adults. In the nymphs, the only positive effect we documented was an increased tendency to feed while in the company of another locust than alone. The adults, on the other hand, showed significant preference for joining others (local enhancement) in both the contexts of feeding and egg laying. Neither nymphs nor adults, however, showed social learning. Our preliminary analyses pointed to locusts as a likely insect that might possess social learning. Our research, when taken together with research on phase-shifts and swarm/marching behaviour of gregarious locusts, suggests that the behavioural dynamics of gregarious locusts may make local enhancement but not social learning beneficial. The possible difference we documented between the nymphs and adults could enable us to further explore the proximate and ultimate mechanisms that underlie socially influenced behaviour. |

Abstract |
The stability of grazing-induced spatial patterns of vegetation was analyzed at two spatial scales (25 m × 20 m areas and 1.6 m × 0.8 m grids) in pastures of contrasting productivity (maximum standing biomass: 130–800 gDM/m2). At both scales, the mosaic of grazed and ungrazed patches was modeled as a Boolean process, calculating cross-variograms to quantify the temporal stability of grazing patterns and its links with local floristic composition were tested. The scale at which stability of vegetation patterns took place in two successive years depended on pasture productivity. Inter-annual stability of large-scale patterns mainly occurred in extensively used fertile pastures grazed by cattle, and in pastures grazed by horses. Less-fertile grasslands were mainly characterized by a fine-scale stability of grazing patterns. Stable fine-scale patterns were often related to the local abundance of legumes and forbs. Stable large-scale patterns of grazing within lightly grazed productive grasslands could result in divergent local vegetation dynamics, which can be seen as an opportunity for restoring biodiversity in fertile grasslands. |
