| Abstract | In the USA, each year, up to one billion birds are estimated to die from colliding with windowpanes (Sabo et al. 2016). A further 573,000 are struck down by wind turbines, along with 888,000 bats (Smallwood 2013). Worldwide, unintended capture in fishing devices is recognized as the single most serious global threat to migratory, long-lived marine taxa including turtles, birds, mammals and sharks (Wallace et al. 2013). Estimates put the number of amphibians killed per year on Australian roads at 5 million (Seiler 2003). The likelihood of a green turtle erroneously ingesting plastic debris, often by mistaking them for food, rose from 30% in 1985 to almost 50% in 2012 (Schuyler et al. 2013). Human-induced rapid environmental change (HIREC, sensu Sih et al. 2011) is filling animals’ environments with new threats which bear little or excessive similarity to those they have encountered in their evolutionary history (Dwernychuk and Boag 1972; Patten and Kelley 2010; Witherington 1997). As a consequence, many of the stimuli involved fall outside the adaptive processing space of animals’ evolutionary perceptual, learning, memory and decision-making systems, making individuals particularly vulnerable to their impact. | ||||

| Title | Testing VHF/GPS Collar Design and Safety in the Study of Free-Roaming Horses | Type | Journal Article | ||

| Abstract | Effective and safe monitoring techniques are needed by U.S. land managers to understand free-roaming horse behavior and habitat use and to aid in making informed management decisions. Global positioning system (GPS) and very high frequency (VHF) radio collars can be used to provide high spatial and temporal resolution information for detecting free-roaming horse movement. GPS and VHF collars are a common tool used in wildlife management, but have rarely been used for free-roaming horse research and monitoring in the United States. The purpose of this study was to evaluate the design, safety, and detachment device on GPS/VHF collars used to collect free-roaming horse location and movement data. Between 2009 and 2010, 28 domestic and feral horses were marked with commercial and custom designed VHF/GPS collars. Individual horses were evaluated for damage caused by the collar placement, and following initial observations, collar design was modified to reduce the potential for injury. After collar modifications, which included the addition of collar length adjustments to both sides of the collar allowing for better alignment of collar and neck shapes, adding foam padding to the custom collars to replicate the commercial collar foam padding, and repositioning the detachment device to reduce wear along the jowl, we observed little to no evidence of collar wear on horses. Neither custom-built nor commercial collars caused injury to study horses, however, most of the custom-built collars failed to collect data. During the evaluation of collar detachment devices, we had an 89% success rate of collar devices detaching correctly. This study showed that free-roaming horses can be safely marked with GPS and/or VHF collars with minimal risk of injury, and that these collars can be a useful tool for monitoring horses without creating a risk to horse health and wellness. | ||||

| 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 | ||

| 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). |

| Abstract | Basic Commercial Court in Ankara wanted a report from our department of forensic medicine about two injury cases due to animal vehicle collision. The reports should include the disability rate and the duration of unfunctionality. After the examination we prepared the reports. Both vehicle collisions happened due to free ranging horse crossing the motorway. Both cases had different types of injury due to trauma. Vehicle collision due to horse crossing the motorway is rarely met in Turkey. Our first case is a man that had upper extremity and facial injury. He uses prothesis due to ear amputation. He has a scar tissue on the right side of his face and left forearm. The other case is three-years-old boy that had cranial bone fracture and cranial hematoma. He has also hemiparesis of the right side of body. Both cases have neurologic sequels but they have no psychiatric sequels. In literature, animal vehicle collisions involve lots of animal species such as kangaroo, deer, camel and moose. Animal vehicle collision involving the horses is rarely met. Forensic medicine specialists should state the causal link between traumatic events and disabilities in order to help justice. Our aim to present the current two cases is investigation of injuries of animal related collision and makes forensic medicine specialists pay attention to the subject of preparing reports about such cases. |
