	Title	Cortisol release, heart rate and heart rate variability, and superficial body temperature, in horses lunged either with hyperflexion of the neck or with an extended head and neck position			Type	Journal Article
	Year	2013	Publication	Journal of Animal Physiology and Animal Nutrition	Abbreviated Journal
	Volume	97	Issue	2	Pages	322-330
	Keywords	animal welfare; equitation; stress; training
	Abstract	Bringing the head and neck of ridden horses into a position of hyperflexion is widely used in equestrian sports. In our study, the hypothesis was tested that hyperflexion is an acute stressor for horses. Salivary cortisol concentrations, heart rate, heart rate variability (HRV) and superficial body temperature were determined in horses (n = 16) lunged on two subsequent days. The head and neck of the horse was fixed with side reins in a position allowing forward extension on day A and fixed in hyperflexion on day B. The order of treatments alternated between horses. In response to lunging, cortisol concentration increased (day A from 0.73 ± 0.06 to 1.41 ± 0.13 ng/ml, p < 0.001; day B from 0.68 ± 0.07 to 1.38 ± 0.13 ng/ml, p < 0.001) but did not differ between days A and B. Beat-to-beat (RR) interval decreased in response to lunging on both days. HRV variables standard deviation of RR interval (SDRR) and RMSSD (root mean square of successive RR differences) decreased (p < 0.001) but did not differ between days. In the cranial region of the neck, the difference between maximum and minimum temperature was increased in hyperflexion (p < 0.01). In conclusion, physiological parameters do not indicate an acute stress response to hyperflexion of the head alone in horses lunged at moderate speed and not touched with the whip. However, if hyperflexion is combined with active intervention of a rider, a stressful experience for the horse cannot be excluded.

	Title	A Systematic Review of Effectiveness of Complementary and Adjunct Therapies and Interventions Involving Equines			Type	Book Whole
	Year	2012	Publication	Health psychology : official journal of the Division of Health Psychology, American Psychological Association	Abbreviated Journal
	Volume	32	Issue		Pages
	Keywords
	Abstract	Objective: This systematic review examines the empirical literature in an emerging body of evidence for the effectiveness of biopsychosocial interventions involving equines across populations with chronic illness or health challenges. Method: Selected quantitative studies published in peer-reviewed journals were reviewed for inclusion; the gray literature and white papers were also explored. Population, Intervention, Comparison, and Outcome (PICO) criteria and Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) were applied to all studies. Fourteen full reports meeting a priori inclusion criteria were extracted from 103 studies accessed through 16 electronic databases and a hand search. Data were synthesized in relation to three research questions informing evidence-based practice. Results: No randomized clinical trials were located. Two studies provided a moderate level of evidence for effectiveness. Nine studies demonstrated statistically significant positive effects. Three studies did not find significant psychosocial effects for the target group, although one found significant positive effects for the comparison group. Conclusion: In the aggregate, the evidence is promising in support of the effectiveness of complementary and adjunct interventions employing equines in the treatment of health challenges. Future studies are needed that utilize rigorous and creative designs, especially longitudinal studies and comparisons with established effective treatments.

	Title	Sheep recognize familiar and unfamiliar human faces from two-dimensional images			Type	Journal Article
	Year	2017	Publication	Royal Society Open Science	Abbreviated Journal
	Volume	4	Issue	11	Pages
	Keywords
	Abstract	One of the most important human social skills is the ability to recognize faces. Humans recognize familiar faces easily, and can learn to identify unfamiliar faces from repeatedly presented images. Sheep are social animals that can recognize other sheep as well as familiar humans. Little is known, however, about their holistic face-processing abilities. In this study, we trained eight sheep (Ovis aries) to recognize the faces of four celebrities from photographic portraits displayed on computer screens. After training, the sheep chose the 'learned-familiar' faces rather than the unfamiliar faces significantly above chance. We then tested whether the sheep could recognize the four celebrity faces if they were presented in different perspectives. This ability has previously been shown only in humans. Sheep successfully recognized the four celebrity faces from tilted images. Interestingly, there was a drop in performance with the tilted images (from 79.22 ± 7.5% to 66.5 ± 4.1%) of a magnitude similar to that seen when humans perform this task. Finally, we asked whether sheep could recognize a very familiar handler from photographs. Sheep identified the handler in 71.8 ± 2.3% of the trials without pretraining. Together these data show that sheep have advanced face-recognition abilities, comparable with those of humans and non-human primates.

	Title	Health and behaviour consequences of feral horse relocation			Type	Journal Article
	Year	2011	Publication	Rangel. J.	Abbreviated Journal
	Volume	33	Issue	2	Pages	173-180
	Keywords	equine, GPS, movement, range.
	Abstract	Despite ongoing projects involving the breeding and release of equids into semi-wild and wild environments, insufficient information is available in the literature that describes strategies used by equids to adapt and survive in a novel environment. The aim of this study was to assess the ability of naïve, feral Equus caballus (horse) mares to cope in a novel feral horse environment and investigate possible reasons why some may not survive this challenge. Four mares taken from a semi-arid desert environment remained in good health but significantly changed their movement behaviour pattern when surrounded by prime grazing habitat in a mesic temperate grassland. Three of the four mares captured from the prime grazing habitat and released in the semi-arid desert habitat died, apparently due to stress and/or starvation, within 8 weeks of release. The fourth mare survived 4 months but lost considerable weight.The group of mares relocated to the semi-arid desert environment had difficulty adapting to relocation and did not take up the movement behaviour strategy of local horses, which required long distance treks from a central water hole to distant feeding areas at least 15 km away. The movement behaviour, range use and health consequences of relocating equids may be of interest to wildlife ecologists, animal behaviourists and horse welfare groups. The observations may be used to guide those intending on relocating managed domestic and native horses to novel habitats.

	Title	Dominance Hierarchies in Horses: Comparing and Contrasting Different Methods for Assessing Hierarchies			Type	Journal Article
	Year	2016	Publication	Ursidae: The Undergraduate Research Journal at the University of Northern Colorado	Abbreviated Journal
	Volume	5	Issue	3	Pages
	Keywords
	Abstract	Understanding animal social structures is imperative when it comes to the care, housing and handling of large herd animals. Knowing how hierarchies are structured, along with environmental and physiological aspects that may affect them, will allow owners and breeders to house and care for their animals. The aim of my study was to better understand two methods used to assess dominance hierarchies in horses, Equus caballus, and to predict which method would be more useful for owners housing domestic horses. I designed an experiment where I compared a structured method, the paired feeding test, with behavioral observations from the horses’ natural setting. I hypothesized that the structured method would not conclude the same dominance hierarchy as the natural observations. I also hypothesized that traits of the horses, such as size or age, would correlate with the hierarchy ranking within a herd. A herd of six individual horses from a small ranch east of Platteville, Colorado was used to test the two methods. I found that the two methods measured different hierarchies. The paired feeding test showed no correlations to any of the physical measurements, as well as did not provide a hierarchy that was similar to the natural dominance observations of the horses. Natural observations established a more linear hierarchy and had significant correlations with weight and overall body size. The results indicate that the paired feeding test may not be a valid method for establishing dominance hierarchies within domestic horses housed in a small range. I recommend use of natural observations over paired feeding tests for ranchers, breeders or owners trying to understand the dominance hierarchies among their herds.

	Title	Vergleich verschiedener Methoden zur Angstextinktion bei Pferden			Type	Manuscript
	Year	2006	Publication		Abbreviated Journal
	Volume		Issue		Pages
	Keywords
	Abstract	Pferde sind Fluchttiere. Ihr Fluchtinstinkt bewirkt, dass sie sich leicht erschrecken und auch in diversen Situationen mit Flucht reagieren. Diese Tatsache ist den meisten Reitern bekannt, nur ist es für den Menschen teilweise schwer, mit dieser Eigenschaft auszukommen und sie zu verstehen oder gar nachzuvollziehen. So kommt es häufig zu Unfällen, die aus der Angst der Pferde resultieren, jedoch vermeidbar gewesen wären, hätte man ankündigende Signale früher erkannt. Des Weiteren kann die Angst eines Pferdes auch durch eine (Ver-) Weigerung, bestimmte Dinge zu tun, sichtbar werden. Diese Weigerung wird in der Reiterei gerne als „Bockigkeit“ und „Ungehorsam“ des Pferdes interpretiert und führt nicht selten zu einer Bestrafung. Insgesamt kann man sagen, dass angstauslösende Reize und die Reaktionen des Pferdes darauf oft falsch eingeschätzt oder falsch interpretiert werden und in der Folge auch falsch damit umgegangen wird. Ein Grund dafür ist sicher das fehlende Wissen über das Verhalten des Pferdes. Mit der vorliegenden Diplomarbeit soll ein Beitrag geleistet werden, das Pferd in seinem Angstverhalten besser zu verstehen. Ziel der Arbeit war es, das Verhalten des Pferdes bei verschiedenen Intensitäten von Angst zu untersuchen. Des Weiteren wurden Methoden untersucht, mit denen man die Angst von Pferden vor bestimmten Reizen und Situationen potentiell lindern kann, was letztendlich auch der Unfallvorbeugung dient. Die vorliegende Diplomarbeit wurde am Haupt- und Landesgestüt Marbach durchgeführt; 24 Junghengste standen hierfür zur Verfügung. Darunter waren 18 Deutsche Warmblüter, 3 Vollblutaraber und 3 Schwarzwälder Füchse (Kaltblüter), somit war auch ein Rassenvergleich möglich. In einem ersten Teil der Arbeit wurde untersucht, wie sich Angst bei Pferden äußert. Hierfür wurde ausgenutzt, dass Pferde ganz generell vor unbekannten, neuen Gegenständen Angst haben (= Neophobie). Zur Angstauslösung dienten als Konfrontationsgegenstände ein Sonnenschirm und eine Plastikplane. Beide Gegenstände waren für die Testpferde unbekannt. Das Verhalten sowie die Herzrate der Tiere wurden während aller Versuche beobachtet und quantifiziert. Nacheiner ersten Konfrontation wurden die Pferde an die Objekte gewöhnt (Extinktionstraining = Angstlöschung) und beobachtet welche Verhaltensymptome sich während dieser Gewöhnung (= Verlust der Neophobie) verändern. Die Hypothese war, dass tatsächliche Angstsymptome während der Gewöhnung immer seltener zu beobachten sind. Zusammenfassung III Als Verhaltensweisen für Angst konnten Ausweichbewegungen und Flucht, Lautäußerungen (Prusten und Schnauben), das Anspannen der Halsmuskulatur sowie das Vordrücken der Oberlippe identifiziert werden. Darüber hinaus wurde gezeigt, dass Abstufungen im Angstverhalten möglich sind: Bei sehr hohem Angstlevel sind Fluchtreaktionen zu beobachten. Bei mittlerem Angstlevel treten Ausweichbewegungen im Schritt und Lautäußerungen (Prusten und Schnauben) auf, bei geringem Angstlevel wird die Halsmuskulatur angespannt und die Oberlippe vorgedrückt. Im Zweiten Teil der Arbeit sollten verschiedene Methoden zur Angst-Extinktionauf ihre Wirksamkeit hin untersucht werden. Verwendet wurde in verschiedenen Testgruppen die Methode der Desensibilisierung (d.h. leichte, schrittweise stärker werdende Exposition gegenüber dem angstauslösenden Reiz), die Desensibilisierung mit Gegenkonditionierung (positive Verstärkung) durch Streicheln bzw. Reiben des Halses und die Desensibilisierung mit Gegenkonditionierung durch Futterbelohnung. Als Kontrollgruppe dienten Pferde, die ohne eine Konfrontation mit dem angstauslösenden Reiz nur über den Versuchplatz geführt wurden. Während des Extinktionstrainings konnte beobachtet werden, dass die Desensibilisierung mit Gegenkonditionierung zu einer schnelleren Extinktion führt als ohne Gegenkonditionierung. Allerdings zeigte ein Vergleich mit der Kontrollgruppe, die das Extinktionstraining nicht erfahren hatte, den gleichen Verlust an Angstverhalten wie die Gruppen mit Extinktionstraining. Dieses Ergebnis wurde so interpretiert, dass die wiederholte Exposition gegenüber angstauslösenden Reizen bei den durchgeführten Verhaltenstests zwar eine Rolle spielt, doch dass auch allein die Beschäftigung mit den Tieren zu einem Verlust von Angstverhalten führt (wahrscheinlich auch aufgrund eines wachsenden Vertrauens zur Führperson, die über das komplette Experiment hin die Gleiche blieb).
