| Abstract | We studied wolfCanis lupus Linnaeus, 1758 -- livestock conflict in central Greece by investigating patterns of 267 verified wolf attacks on livestock for 21 months. Wolves attacked adult goats 43% and cattle 218% more than expected, whereas sheep 41% less than expected from their availability. Wolves killed less than four sheep or goats in 79%, and one cow or calf in 74% of depredation events, respectively. We recorded higher attack rates during wolf post-weaning season. Wolf attacks on strayed, or kept inside non predator-proof enclosures, sheep and goats, were on average two to four times respectively more destructive than those when livestock was guarded by a shepherd. Sheepdog use reduced losses per attack. Optimal sheepdog number ranged from 3 to 9 animals depending on flock size. Losses per attack were positively related to the number of wolves involved. Total losses per farm were positively correlated with the size of livestock unit but percentage losses per capita increased with decreasing flock size. Management implications to mitigate livestock depredation are discussed. | ||||

| Abstract | By definition, punishment makes a response less likely in the future. Because horses are largely trained by negative reinforcement, they are susceptible to inadvertent punishment. Delays in the release of pressure can make desirable responses less likely and thus punish them. This study examines the correct use of negative reinforcement and identifies a continuum between poorly timed negative reinforcement and punishment. It explores some of the problems of non-contingent punishment and the prospect of learned helplessness and experimental neurosis. It concludes by introducing the concept of ethical equitation. | ||||

| Title | Stressbelastung bei Pferden in Abhängigkeit des Haltungssystems | Type | Manuscript | ||
| Year |
2009 | Publication | Abbreviated Journal | ||
| Volume | Issue | Pages | |||
| Keywords | |||||
| Abstract | Pferdegerechte Haltungssysteme spielen bei der heutigen Nutzung des Freizeit- oder Sportpartners Pferd eine wichtige Rolle, da naturnahe Haltungsbedingungen nur in seltenen Fällen zu realisieren sind. Sämtliche Aufstallungsformen müssen als Kompromiss angesehen werden und bieten somit Vor- und Nachteile. Die vorliegende Untersuchung verfolgte den Zweck, die Stressbelastung von Pferden in verschiedenen Haltungssystemen zu erfassen und vergleichend zu beurteilen. Während der von Mai 2006 bis Juli 2007 durchgeführten Versuche wurden 24 zwei- bis dreijährige Hannoveranerstuten für jeweils 4 Wochen in insgesamt 6 verschiedenen Haltungsformen aufgestallt. Die Haltungsvarianten beinhalteten die Einzelbox (Variante 1), die Einzelbox mit einem frei zugänglichem Paddock (Variante 2), die gemeinsame Haltung von zwei Pferden in zwei Boxen und einem angeschlossenen frei zugänglichem Auslauf (Variante 3) und die Gruppenhaltung von 6 Pferden in einer Mehrraumauslaufhaltung (Variante 4 – 6). Die Haltungsvariante 4 differierte von den Varianten 5 und 6 durch seinen ungegliederten Liegebereich. In den Variante 5 und 6 wurde der Liegebereich der Gruppenhaltung durch eine über die halbe Breite reichende Trennwand in zwei Bereiche unterteilt. Die Trennwand befand sich in Haltungsvariante 5 im rechten Winkel an die Außenwand grenzend, während sie in Variante 6 an der der Stallgasse zugewandten Seite des Liegebereichs aufgestellt wurde. Um eine Vergleichbarkeit mit einem Reitpferd zu schaffen, wurden alle Pferde in allen Haltungssystemen täglich für circa eine Stunde in einer Freilaufanlage bewegt. Die Stressbelastung wurde mittels der Messung der Herzfrequenzvariabilität (Parameter pNN50 und SD1) und der Bestimmung fäkaler Cortisolmetaboliten erfasst. Zusätzlich wurden Videoauswertungen hinsichtlich der Beobachtung von Verhaltensauffälligkeiten in den Haltungsvarianten 1 und 2 durchgeführt. Die durchschnittlich niedrigste Stressbelastung erfuhren die Pferde durch die Haltungsvarianten 4 (pNN50: 46,32 %, SD1:158,58 ms, Cortisolmetaboliten: 21,01nmol/kg Kot) und 6 (pNN50: 47,1 %, SD1: 144,62 ms, Cortisolmetaboliten: 21,01 nmol/kg Kot). Die 141 Auswertung der pNN50- und Cortisolmetabolitenwerte ergab die größte Stressbelastung der Pferde in den Varianten 1 (pNN50: 42,81 %, SD1: 134,52 ms, Cortisolmetaboliten: 28,56 nmol/kg Kot) und 3 (pNN50: 42,41 %, SD1: 135,36, Cortisolmetaboliten: 28,60 nmol/kg Kot). Die Auswertung der SD1-Werte zeigte zusätzlich noch eine hohe Stressbelastung der Pferde in der Variante 5 (pNN50: 44,83 %, SD1: 119,24 ms, Cortisolmetaboliten: 27,18 nmol/kg Kot). Die Haltungsvariante 2 (pNN50: 45,77 %, SD1: 144,25 ms, Cortisolmetaboliten: 27,59 nmol/kg Kot) beziehungsweise die Varianten 2 und 5 (bei der Betrachtung der pNN50- und der Cortisolmetabolitenwerte) verursachten im Durchschnitt eine mittlere Stressbelastung. Teilweise waren die Unterschiede jedoch zu gering um die Signifikanzgrenze zu überschreiten. Die Betrachtung der einzelnen Pferde und der Pferdegruppen ergab große interindividuelle Unterschiede und deutliche gruppenspezifische Gemeinsamkeiten. Die Position eines Tieres in der Rangordnung hatte in diesen Untersuchungen bei der Betrachtung der Mittelwerte keinen Einfluss auf die Stressbelastung in Abhängigkeit der Haltungsvariante. Vielmehr zeigten sich auch hier deutliche individuelle Unterschiede in der Stressanfälligkeit und den Vorlieben der einzelnen Pferde bezüglich der verschiedenen Haltungssysteme. Die Analyse der Videoaufzeichnungen ergab, dass mehrere Pferde Kreisbewegungen in der Einzelbox ohne Auslauf (Variante 1) zeigten, während in der Variante 2 (Paddockbox) kein Pferd durch Kreisbewegungen auffiel. Andere Verhaltensauffälligkeiten oder gar Verhaltensstörungen wurden nicht beobachtet. Bei der Auswertung der Aufenthaltshäufigkeit und der Aufenthaltesdauer in den 4 Boxenquadranten zeigten sich einige Pferde sehr aktiv, was ein Hinweis auf eventuelle Unruhe oder Nervosität sein kann, während andere Pferde im Vergleich zum Gruppendurchschnitt sehr ruhig wirkten, da sie sich in der Box kaum bewegten und über lange Zeitabschnitte in einem Quadranten standen. Obwohl die Gruppenhaltung für die Mehrzahl der Pferde eine geringere Stressbelastung bedeutete und auch hinsichtlich des Bewegungs- und Sozialverhaltens am artgerechtesten einzustufen ist, sollte für jedes Pferd individuell unter Berücksichtigung seines Alters, seiner Rasse, seines Nutzungsgrades, aber vor allem seines Charakters und seiner Erfahrungen im Sozialverhalten ein passendes großzügig bemessenes Haltungssystem ermittelt werden, um 142 die durch das Haltungssystem ausgeübte Stressbelastung zu minimieren und das Wohlbefinden der Pferde zu steigern. |

| Abstract | Horse domestication revolutionized transport, communications, and warfare in prehistory, yet the identification of early domestication processes has been problematic. Here, we present three independent lines of evidence demonstrating domestication in the Eneolithic Botai Culture of Kazakhstan, dating to about 3500 B.C.E. Metrical analysis of horse metacarpals shows that Botai horses resemble Bronze Age domestic horses rather than Paleolithic wild horses from the same region. Pathological characteristics indicate that some Botai horses were bridled, perhaps ridden. Organic residue analysis, using δ13C and δD values of fatty acids, reveals processing of mare's milk and carcass products in ceramics, indicating a developed domestic economy encompassing secondary products. | ||||

| Volume | 9 | Issue | 1 | Pages | 12 |
| Keywords | |||||
| Abstract | Sensing bitter tastes is crucial for many animals because it can prevent them from ingesting harmful foods. This process is mainly mediated by the bitter taste receptors (T2R), which are largely expressed in the taste buds. Previous studies have identified some T2R gene repertoires, and marked variation in repertoire size has been noted among species. However, the mechanisms underlying the evolution of vertebrate T2R genes remain poorly understood. | ||||

| Abstract | Abstract When living in a group, individuals have to make trade-offs, and compromise, in order to balance the advantages and disadvantages of group life. Strategies that enable individuals to achieve this typically affect inter-individual interactions resulting in nonrandom associations. Studying the patterns of this assortativity using social network analyses can allow us to explore how individual behavior influences what happens at the group, or population level. Understanding the consequences of these interactions at multiple scales may allow us to better understand the fitness implications for individuals. Social network analyses offer the tools to achieve this. This special issue aims to highlight the benefits of social network analysis for the study of primate behaviour, assessing it's suitability for analyzing individual social characteristics as well as group/population patterns. In this introduction to the special issue, we first introduce social network theory, then demonstrate with examples how social networks can influence individual and collective behaviors, and finally conclude with some outstanding questions for future primatological research.

| Title | Lack of standardization in reporting motor laterality in the domestic dog (Canis familiaris) | Type | Journal Article | ||

| Abstract | Over the past 2 decades, numerous studies have been undertaken to assess motor laterality in the domestic dog. In anticipation of growth in this area of enquiry, we decided to review the literature on canine motor biases to identify any shortcomings, reflect on the lessons to be learned from and offer ways forward for future research into canine laterality. The aim of this review is to (i) summarize motor laterality findings in the dog, (ii) highlight areas lacking in standardization, and (iii) propose necessary criteria for future tests and global reporting protocols. Our review of the literature highlighted the lack of standardization between studies in task selection, sample size, number of behavior scores recorded, and the methods by which motor laterality were classified and reported. This review illustrates the benefits of standardizing methods of motor laterality assessment so that comparisons can be made between the populations sampled. By adopting such an approach, researchers should mutually benefit as motor laterality data could then be compared and subjected to meta-analysis. | ||||

| Abstract | Sensory lateralization in dogs (n = 74) was investigated in this study using our innovation, the Sensory Jump Test. This required the modification of head halters to create three different ocular treatments (binocular, right, and left monocular vision) for eye preference assessment in a jumping task. Ten jumps were recorded as a jump set for each treatment. Measurements recorded included (i) launch and landing paws, (ii) type of jump, (iii) approach distance, (iv) clearance height of the forepaw, hindpaw, and the lowest part of the body to clear the jump, and (v) whether the jump was successful. Factors significantly associated with these jump outcomes included ocular treatment, jump set number, and replication number. Most notably, in the first jump set, findings indicated a left hemispheric dominance for the initial navigation of the Sensory Jump Test, as left monocular vision (LMV) compromised of jumping more than right monocular (RMV) and binocular vision, with a significantly reduced approach distance and forepaw clearance observed in dogs with LMV. However, by the third jump set, dogs undergoing LMV launched from a greater approach distance and with a higher clearance height, corresponding to an increase in success rate of the jump, in comparison with RMV and binocular vision dogs. A marginally non-significant RMV bias was observed for eye preference based on the laterality indices for approach distance (P = 0.060) and lowest body part clearance height (P = 0.067). A comparison between eye preference and launching or landing paws showed no association between these measures of sensory and motor laterality. To our knowledge, this is the first study to report on sensory lateralization in the dog, and furthermore, to compare both motor and sensory laterality in dogs. | ||||
