  Title An evaluation of long-term preservation methods for brown bear (Ursus arctos) faecal DNA samples Type Journal Article
  Year 2002 Publication Conservation Genetics Abbreviated Journal Conservat. Genet.  
  Volume (down) 3 Issue 4 Pages 435-440  
  Keywords  
  Abstract Relatively few large-scale faecal DNA studieshave been initiated due to difficulties inamplifying low quality and quantity DNAtemplate. To improve brown bear faecal DNA PCRamplification success rates and to determinepost collection sample longevity, fivepreservation methods were evaluated: 90%ethanol, DETs buffer, silica-dried, oven-driedstored at room temperature, and oven-driedstored at -20 °C. Preservationeffectiveness was evaluated for 50 faecalsamples by PCR amplification of a mitochondrialDNA (mtDNA) locus (~146 bp) and a nuclear DNA(nDNA) locus (~200 bp) at time points of oneweek, one month, three months and six months. Preservation method and storage timesignificantly impacted mtDNA and nDNAamplification success rates. For mtDNA, allpreservation methods had >= 75% success atone week, but storage time had a significantimpact on the effectiveness of the silicapreservation method. Ethanol preserved sampleshad the highest success rates for both mtDNA(86.5%) and nDNA (84%). Nuclear DNAamplification success rates ranged from 26-88%, and storage time had a significant impacton all methods but ethanol. Preservationmethod and storage time should be importantconsiderations for researchers planningprojects utilizing faecal DNA. We recommendpreservation of faecal samples in 90% ethanolwhen feasible, although when collecting inremote field conditions or for both DNA andhormone assays a dry collection method may beadvantageous.

  Title Systematic Review of the Empirical Evidence of Study Publication Bias and Outcome Reporting Bias Type Journal Article
  Year 2008 Publication Plos One Abbreviated Journal Plos One  
  Volume (down) 3 Issue 8 Pages e3081  
  Keywords  
  Abstract Background The increased use of meta-analysis in systematic reviews of healthcare interventions has highlighted several types of bias that can arise during the completion of a randomised controlled trial. Study publication bias has been recognised as a potential threat to the validity of meta-analysis and can make the readily available evidence unreliable for decision making. Until recently, outcome reporting bias has received less attention. Methodology/Principal Findings We review and summarise the evidence from a series of cohort studies that have assessed study publication bias and outcome reporting bias in randomised controlled trials. Sixteen studies were eligible of which only two followed the cohort all the way through from protocol approval to information regarding publication of outcomes. Eleven of the studies investigated study publication bias and five investigated outcome reporting bias. Three studies have found that statistically significant outcomes had a higher odds of being fully reported compared to non-significant outcomes (range of odds ratios: 2.2 to 4.7). In comparing trial publications to protocols, we found that 40-62% of studies had at least one primary outcome that was changed, introduced, or omitted. We decided not to undertake meta-analysis due to the differences between studies. Conclusions Recent work provides direct empirical evidence for the existence of study publication bias and outcome reporting bias. There is strong evidence of an association between significant results and publication; studies that report positive or significant results are more likely to be published and outcomes that are statistically significant have higher odds of being fully reported. Publications have been found to be inconsistent with their protocols. Researchers need to be aware of the problems of both types of bias and efforts should be concentrated on improving the reporting of trials.

  Title Stress, social behavior, and resilience: Insights from rodents Type Journal Article
  Year 2015 Publication Neurobiology of Stress Abbreviated Journal Neurobiol. Stress  
  Volume (down) 1 Issue Stress Resilience Pages 116-127  
  Keywords Stress; Anxiety; Social behavior; Sociality; Social stress; Social buffering  
  Abstract The neurobiology of stress and the neurobiology of social behavior are deeply intertwined. The social environment interacts with stress on almost every front: social interactions can be potent stressors; they can buffer the response to an external stressor; and social behavior often changes in response to stressful life experience. This review explores mechanistic and behavioral links between stress, anxiety, resilience, and social behavior in rodents, with particular attention to different social contexts. We consider variation between several different rodent species and make connections to research on humans and non-human primates.

  Title Behavioural and physiological responses of therapy horses to mentally traumatized humans Type Journal Article
  Year 2018 Publication Applied Animal Behaviour Science Abbreviated Journal  
  Volume (down) Issue Pages  
  Keywords Equine-assisted therapy; Ptsd; Horse; Behaviour; Cortisol; Heart rate  
  Abstract The benefits to humans of equine-assisted therapy (EAT) have been well-researched, however few studies have analyzed the effects on the horse. Understanding how differing mental states of humans affect the behaviour and response of the horse can assist in providing optimal outcomes for both horse and human. Four humans clinically diagnosed and under care of a psychotherapist for Post-Traumatic Stress Disorder (PTSD) were matched physically to four neurotypical control humans and individually subjected to each of 17 therapy horses loose in a round pen. A professional acting coach instructed the control humans in replicating the physical movements of their paired PTSD individual. Both horses and humans were equipped with a heart rate (HR) monitor recording HR every 5secs. Saliva samples were collected from each horse 30 min before and 30 min after each trial to analyze cortisol concentrations. Each trial consisted of 5 min of baseline observation of the horse alone in the round pen after which the human entered the round pen for 2 min, followed by an additional 5 min of the horse alone. Behavioural observations indicative of stress in the horse (gait, head height, ear orientation, body orientation, distance from the human, latency of approach to the human, vocalizations, and chewing) were retrospectively collected from video recordings of each trial and analyzed using a repeated measures GLIMMIX with Tukey's multiple comparisons for differences between treatments and time periods. Horses moved slower (p < 0.0001), carried their head lower (p < 0.0001), vocalized less (p < 0.0001), and chewed less (p < 0.0001) when any human was present with them in the round pen. Horse HR increased in the presence of the PTSD humans, even after the PTSD human left the pen (p < 0.0001). Since two of the PTSD/control human pairs were experienced with horses and two were not, a post-hoc analysis showed that horses approached quicker (p < 0.016) and stood closer (p < 0.0082) to humans who were experienced with horses. Horse HR was lower when with inexperienced humans (p < 0.0001) whereas inexperienced human HR was higher (p < 0.0001). Horse salivary cortisol did not differ between exposure to PTSD and control humans (p > 0.32). Overall, behavioural and physiological responses of horses to humans are more pronounced based on human experience with horses than whether the human is diagnosed with a mental disorder. This may be a reflection of a directness of movement associated with humans who are experienced with horses that makes the horse more attentive. It appears that horses respond more to physical cues from the human rather than emotional cues. This knowledge is important in tailoring therapy programs and justifying horse responses when interacting with a patient in a therapy setting.

  Title Social learning in Horses: Differs from individual learning only in the learning stimulus and not in the learning mechanisms Type Abstract
  Year 2018 Publication 14th Meeting of the Internatinoal Society for Equitation Science Abbreviated Journal 14th Meeting ISES  
  Volume (down) Issue Pages  
  Keywords horse; individual learning; learning mechanisms; learning stimuli; social learning  
  Abstract Equine welfare can be enhanced by applying species specific training. This may incorporate social learning, as horses are highly social and social stimuli are of primary importance. Social learning is comparable to individual learning in its learning mechanisms, differing primarily in the way it is stimulated. Our initial study showed that horses of different breeds (N = 38) follow humans after observing other horses doing so, but only if the observed horse was familiar to and higher ranking than the observer (Fisher's exact test: N = 12, P = 0.003). A second study showed that horses and ponies (N = 25) learned to pull a rope to open a feeding apparatus after observing demonstrations by conspecifics, again, only if the demonstrating horse was older and higher ranking than the observer (Fisher's combination test, N = 3, v2 = 27.71, p = 0.006). Our third approach showed that horses and ponies (N = 24) learned to press a switch to open a feeding apparatus after observing a familiar person (GzLM: N = 24, z = 2.33, P = 0.02). Most recently, we confronted horses and ponies (N = 50) with persons demonstrating different techniques for opening a feeding apparatus. In this study we investigated whether the horses would copy the demonstrators' techniques or apply their own. Here only some horses copied the technique, and most of the successful learners used their mouths irrespective of the demonstrators' postures (Chi Square Test: N = 40, df = 2, &#967;2 = 31.4, p < 0.001). In all the approaches social stimuli elicited learning processes in the test horses, while only a few individuals in the control groups mastered the tasks by individual learning. The following behaviour observed in the initial study may have been facilitated by a social stimuli (social facilitation), and the opening of the feed boxes in the subsequent studies appear to be mostly the result of enhancement (social enhancement). Some horses may have used the social stimuli at first and continued their learning process by individual trial and error. However, the horses were also selective in whom and some in how to copy. This may have been conditioned (socially conditioned) or the result of simple forms of reasoning on the reliability of the particular information provided by demonstrators of certain social ranks or social positions, as high ranking and familiar horses and familiar persons were copied and some imitated exactly.

Lay person message: Traditional riding instructions suggest that horses learn by observing other horses. For example, older, more experienced driving horses are used for initial training of young driving horses. We have shown that horses indeed use learning stimuli provided by other horse, as well as by humans. Horses readily accept stimuli observed in high ranking and familiar horses, and familiar persons. Such stimuli elicit learning processes which are comparable to individual learning. We suggest applying social learning whenever possible, as it is much faster and less stressful than individual learning, where learners experience negative outcomes in trial and error learning.

  Title Vergleich verschiedener Methoden zur Angstextinktion bei Pferden Type Manuscript
  Year 2006 Publication Abbreviated Journal  
  Volume (down) 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).
