	Title	Pferde in Gruppenhaltung: Eine Betrachtung aus tierärztlicher Sicht unter besonderer Berücksichtigung des Verletzungsrisikos [Group housing of horses: veterinary considerations with a focus on the prevention of bite and kick injuries]			Type	Journal Article
	Year	2006	Publication	Pferdeheilkunde	Abbreviated Journal

	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	Lateralization of agonistic and vigilance responses in Przewalski horses (Equus przewalskii)			Type	Journal Article
	Year	2014	Publication	Applied Animal Behaviour Science	Abbreviated Journal
	Volume	151	Issue		Pages	43-50
	Keywords	Behavioural lateralization: Eye preference; Limb preference; Aggression; Vigilance; Reactivity; Przewalski horses
	Abstract	tEye and limb preferences were scored in the closest undomesticated relative of Equuscaballus using the same methods as used previously to study laterality in feral horses.Observations were made of 33 Przewalski horses (Equus ferus przewalskii) (male N = 20,female N = 13) living under natural social conditions on a large reserve in France. Signifi-cant left-eye/side biases were found in agonistic interactions within harem bands (M ± SEbias to left 58% ± 0.01 for threats, P < 0.001; 68% ± 0.05 for attacks; P < 0.001) and in stallionfights (threats, 52% ± 0.01 left, P < 0.001; attacks, 63% ± 0.02 left, P < 0.001): as many as 80%of the horses were significantly lateralized in attack responses within harem bands. Lat-erality of vigilance was measured as lifting up the head from grazing and turning it to theleft or right side: a directional bias to the left was found (M ± SE 53% ± 0.02 left, P < 0.001).Side bias in reactivity was calculated as the percent of head lifts above the level of thewithers on the left or right side and this was also left side biased (M ± SE 73% ± 0.03 left,P < 0.001). These results indicate right-hemisphere specialization for control of aggressionand responses to novelty. The left bias in attack scores within harem bands was strongerin males than females (P = 0.024) and in immature than adult horses (P = 0.032). Immaturehorses were also more strongly lateralized than adults in vigilance scores (P = 0.022), whichmay suggest that experience reduces these side biases. Our results show that Przewalskihorses exhibit left eye preferences, as do feral horses, and do so even more strongly thanferal horses. Considering feral and Przewalski horses together, we deduce that ancestralhorses had similar lateral biases. Also similar to feral horses, the Przewalski horses showedno significant forelimb preference at the group level or in the majority of horses at theindividual level, confirming the hypothesis that previously reported limb preferences indomestic breeds are entrained or generated by breed-specific selection.

	Title	Close social associations in animals and humans: functions and mechanisms of friendship			Type
	Year	2010	Publication	Behaviour	Abbreviated Journal
	Volume	147	Issue	11	Pages	1379
	Keywords	Both humans and group-living animals associate and behave affiliatively more with some individuals than others. Human friendship has long been acknowledged, and recently scientists studying animal behaviour have started using the term friendship for close social associates in animals. Yet, while biologists describe friends as social tools to enhance fitness, social scientists describe human friendship as unconditional. We investigate whether these different descriptions reflect true differences in human friendship and animal close social associations or are a by-product of different research approaches: namely social scientists focussing on proximate and biologists on ultimate explanations. We first stress the importance of similar measures to determine close social associations, thereafter examine their ultimate benefits and proximate motivations, and discuss the latest findings on the central-neural regulation of social bonds. We conclude that both human friendship and animal close social associations are ultimately beneficial. On the proximate level, motivations for friendship in humans and for close social associations in animals are not necessarily based on benefits and are often unconditional. Moreover, humans share with many animals a similar physiological basis of sociality. Therefore, biologists and social scientist describe the same phenomenon, and the use of the term friendship for animals seems justified.

	Title	Cortisol levels in hair reflect behavioural reactivity of dogs to acoustic stimuli			Type	Journal Article
	Year	2013	Publication	Research in Veterinary Science	Abbreviated Journal
	Volume	94	Issue	1	Pages	49-54
	Keywords	Dogs; Behaviour; Cortisol; Hair; Acoustic stimuli
	Abstract	Cortisol levels in hair samples were examined in fourteen domestic dogs and related to the dogs’ responses to different acoustic stimuli. Stimuli were playbacks of species-typical vocalizations recorded during three different situations (“disturbance”, “isolation” and “play” barks) and the sounds of a thunderstorm. Hair samples were collected at 9:00 h and 17:00 h two weeks after the behavioural tests. Results showed that behavioural reactivity to playback of the various stimuli correlates with cortisol levels in hair samples collected at 9:00 h, and the same was the case for the separate measures of behaviour (i.e. hiding, running away, seeking attention from the tester, panting and lowering of the body posture). Hence, levels of cortisol in hair appear to reflect the dog’s chronic state of emotional reactivity, or temperament.

	Title	Choosing an appropriate index to construct dominance hierarchies in animal societies: a comparison of three indices			Type	Journal Article
	Year	2010	Publication	Animal Behaviour	Abbreviated Journal
	Volume	79	Issue	3	Pages	631-636
	Keywords	dominance behaviour; dominance hierarchy; dominance index; dominance rank; Ropalidia cyathiformis; Ropalidia marginata; social wasp
	Abstract	A plethora of indices have been proposed and used to construct dominance hierarchies in a variety of vertebrate and invertebrate societies, although the rationale for choosing a particular index for a particular species is seldom explained. In this study, we analysed and compared three such indices, viz Clutton-Brock et al.'s index (CBI), originally developed for red deer, Cervus elaphus, David's score (DS) originally proposed by the statistician H. A. David and the frequency-based index of dominance (FDI) developed and routinely used by our group for the primitively eusocial wasps Ropalidia marginata and Ropalidia cyathiformis. Dominance ranks attributed by all three indices were strongly and positively correlated for both natural data sets from the wasp colonies and for artificial data sets generated for the purpose. However, the indices differed in their ability to yield unique (untied) ranks in the natural data sets. This appears to be caused by the presence of noninteracting individuals and reversals in the direction of dominance in some of the pairs in the natural data sets. This was confirmed by creating additional artificial data sets with noninteracting individuals and with reversals. Based on the criterion of yielding the largest proportion of unique ranks, we found that FDI is best suited for societies such as the wasps belonging to Ropalidia, DS is best suited for societies with reversals and CBI remains a suitable index for societies such as red deer in which multiple interactions are uncommon.

	Title	Bewertung einer Faltschieberanlage in einem Reitstall mit Paddockboxen[Assessment of a v-form scraper in a horse barn with paddock boxes]			Type	Journal Article
	Year	2014	Publication	Landtechnik, Agricultural Engineering,	Abbreviated Journal
	Volume	68	Issue	4	Pages	242-247
	Keywords	Entmistungstechnik, Arbeitswirtschaft, Pferdeverhalten [Manure removal systems, working time requirement, horse behaviour]
	Abstract	In der vorliegenden Untersuchung werden in einem Praxisbetrieb die Verfahrenskosten eines Faltschiebers erhoben. Aufgrund des reduzierten Arbeitszeitaufwandes ergibt sich durch den Einsatz des Faltschiebers eine jährliche Kostenersparnis in Höhe von 78 € je Pferd. Durch die Mechanisierung der Entmistung kann fast 30 % der Arbeitszeit in der Pensionspferdehaltung eingespart werden. Beim Einsatz einer Entmistungstechnik spielt jedoch nicht nur die Ökonomie, sondern darüber hinaus auch das Pferdeverhalten eine Rolle. Im selben Praxisbetrieb wird nach Installation der Faltschieberanlage das Pferdeverhalten beim Erstkontakt mit dem Schieber beobachtet. Dabei zeigt sich, dass die Pferde den direkten Kontakt mit der Entmistungstechnik und somit kritische Situationen vermeiden. [In the survey at hand, the procedural costs for a v-form scraper are gathered. In the process, it is found that due to the reduced working time requirement the use of a v-form scraper saves € 78/horse/year. The mechanization of manure removal can reduce working time in horse keeping by almost 30 percent. However, using manure removal systems, the profitability is not the only crucial criteria. The behaviour of the horses plays an essential role, too. Moreover the horses’ behaviour when first encountering the manure scraper is observed. The study reveals that the horses avoid contact with the scraper and thereby also shirk critical situations.]

	Title	Dominance rank is associated with body condition in outdoor-living domestic horses (Equus caballus)			Type	Journal Article
	Year	2015	Publication	Applied Animal Behaviour Science	Abbreviated Journal
	Volume		Issue		Pages
	Keywords	Equine; fatness; obesity; social behaviour; displacement
	Abstract	Abstract The aim of our study was to explore the association between dominance rank and body condition in outdoor group-living domestic horses, Equus caballus. Social interactions were recorded using a video camera during a feeding test, applied to 203 horses in 42 herds. Dominance rank was assigned to 194 individuals. The outcome variable body condition score (BCS) was recorded using a 9-point scale. The variables age and height were recorded and considered as potential confounders or effect modifiers. Results were analysed using multivariable linear and logistic regression techniques, controlling for herd group as a random effect. More dominant (p = 0.001) individuals generally had a higher body condition score (p = 0.001) and this association was entirely independent of age and height. In addition, a greater proportion of dominant individuals fell into the obese category (BCS >= 7/9, p = 0.005). There were more displacement encounters and a greater level of interactivity in herds that had less variation in age and height, lending strength to the hypothesis that phenotypic variation may aid cohesion in group-living species. In addition there was a strong quadratic relationship between age and dominance rank (p < 0.001), where middle-aged individuals were most likely to be dominant. These results are the first to link behavioural predictors to body condition and obesity status in horses and should prompt the future consideration of behavioural and social factors when evaluating clinical disease risk in group-living animals.

	Title	Salivary IgA: a Possible Stress Marker In Dogs			Type	Abstract
	Year	1995	Publication	Animal Welfare	Abbreviated Journal
	Volume	4	Issue	4	Pages	339-350
	Keywords	Animal Welfare; Behaviour; Cortisol; Dog; Salivary Iga (S-Iga); Stress; Well-Being
	Abstract	Stress in humans has been reported to be associated with a decrease in the salivary immunoglobulin A (s-IgA) levels enabling the possible use of s-IgA to assess stress. Prolonged stress, if reliably assessed in a non-invasive manner, may be used to assess animal welfare. This study analysed groups of dogs undergoing physical and temperamental training and s-IgA levels were measured by rocket immunoelectrophoresis in prospective samples. Behavioural assessment was carried out and cortisol levels in saliva were measured by ELISA. A significant negative correlation (P < 0.007) between the logarithmic cortisol concentrations and s-IgA levels in saliva was recorded. The behavioural assessment of the dogs agreed well with the biochemical markers. It is concluded that IgA levels in saliva may be a useful marker of dog well-being and that stress results in decreased s-IgA levels.

	Title	Cognition and learning in horses (Equus caballus): What we know and why we should ask more			Type	Journal Article
	Year	2016	Publication	Behavioural Processes	Abbreviated Journal
	Volume	126	Issue		Pages	121-131
	Keywords	Horse behaviour; Horse welfare; Learning; Social cognition
	Abstract	Abstract Horses (Equus caballus) have a rich history in their relationship with humans. Across different cultures and eras they have been utilized for work, show, cultural rituals, consumption, therapy, and companionship and continue to serve in many of these roles today. As one of the most commonly trained domestic animals, understanding how horses learn and how their relationship with humans and other horses impacts their ability to learn has implications for horse welfare, training, husbandry and management. Given that unlike dogs and cats, domesticated horses have evolved from prey animals, the horse-human relationship poses interesting and unique scientific questions of theoretical value. There is still much to be learned about the cognition and behaviour of horses from a scientific perspective. This review explores current research within three related areas of horse cognition: human-horse interactions, social learning and independent learning in horses. Research on these topics is summarized and suggestions for future research are provided.

	Title	Influence of extrinsic variables on activity and habitat selection of lowland tapirs (Tapirus terrestris) in the coastal sand plain shrub, southern Brazil			Type	Journal Article
	Year	2010	Publication	Mammalian Biology – Zeitschrift für Säugetierkunde	Abbreviated Journal
	Volume	75	Issue	3	Pages	219-226
	Keywords	Behaviour; Circadian rhythmic; Moonlight; Rainfall; Temperature
	Abstract	The objectives of this research were to: 1. evaluate the circadian activity patterns of lowland tapirs (Tapirus terrestris) throughout the seasons and 2. study the influence of moonlight, temperature and rainfall on the activity patterns and habitat selection of this species, in the coastal sand shrub in southern Brazil. From June 2005 to June 2006, eight tapirs were monitored in a large enclosure containing open and vegetation-covered areas, using four camera traps. Differences in activity patterns within seasons were found. Tapir predominately presented nocturnal-crepuscular activity; however, they differed in the winter, with cathemeral activity patterns. Covered areas were mostly used during periods of extreme temperatures, with less diurnal and more nocturnal activities within these areas, on hotter days. Activity in open areas mainly occurred during periods of intermediate temperatures, both during the day and in the night. Moonlight intensity did not influence nocturnal activities. On days of precipitation of 34 mm or more, there was no record of open-area activities, despite constant activity in covered-area.
