Title | Position of the head is not associated with changes in horse vision | Type | Journal Article | ||
Year | 2008 | Publication | Equine Veterinary Journal | Abbreviated Journal | |
Volume | 40 | Issue | 6 | Pages | 599-601 |
Keywords | horse; horse vision; head position; pupil rotation | ||||
Abstract | It has become accepted that the horse cannot see directly in front when the nose is lowered and must therefore rely on the rider. We tested the hypothesis that this conclusion would be correct only if the horse did not adjust the eyeball horizontal axis to changes of the head position. The results of the present study suggest that it is unlikely that horses have limited vision in relation to their head position when driven by the rider, and that the horse maintains the optimal horizontal eyeball position regardless of head position relative to the ground. | ||||

Title | The CRF System Mediates Increased Passive Stress-Coping Behavior Following the Loss of a Bonded Partner in a Monogamous Rodent | Type | Journal Article | ||
Year | 2008 | Publication | Abbreviated Journal | Neuropsychopharmacology | |

Keywords | prairie vole; passive stress-coping; forced swim test; tail suspension test; elevated plus-maze; hypothalamo–pituitary–adrenal axis | ||||
Abstract | Social relationships significantly influence physiology and behavior, including the hypothalamo–pituitary–adrenal axis, anxiety, and mental health. Disruption of social bonds through separation or death often results in profound grieving, depression, and physical illness. As the monogamous prairie vole forms enduring, selective pair bonds with the mating partner, they provide an animal model to study the physiological consequences of pair bonding and, thus, the loss of the bonded partner. Male prairie voles were paired with a novel female or male sibling. After 5 days, half of the males of each group were separated from the partner. Elevated plus-maze, forced swim, and tail suspension tests were used to assess anxiety-like and passive stress-coping behaviors indicative of depressive-like behavior. Following 4 days of separation from the female but not the male partner, experimental males displayed increased passive stress-coping. This effect was abolished by long-term intracerebroventricular infusion of a nonselective corticotropin-releasing factor (CRF) receptor antagonist without disrupting the bond itself. Both CRF type 1 and 2 receptors were involved in the emergence of passive stress-coping behavior. Furthermore, pairing with a female was associated with elevated CRF mRNA in the bed nucleus of the stria terminalis, and partner loss elicited a pronounced increase in circulating corticosteroid and adrenal weight. We speculate that the CRF system may mediate an aversive affect following separation from the female partner, which may facilitate proximity seeking between the pair-bonded individuals. Hence, the prairie vole model may provide insights into brain mechanisms involved in the psychopathological consequences of partner loss. |

Title | Häufigkeiten von Erkrankungen und Verletzungen in der Schweizer Pferdepopulation | Type | Journal Article | ||
Year | 2008 | Publication | Schweizer Archiv für Tierheilkunde | Abbreviated Journal | |
Volume | 150 | Issue | 8 | Pages | 399-408 |
Keywords | |||||
Abstract | Bei einer für die Schweiz repräsentativ und zufällig ausgewählten Stichprobe von 2912 Pferden und Ponys wurden mittels Fragebogen Daten zum aktuellen Gesundheitszustand und zum Auftreten von Erkrankungen und Verletzungen während der vergangenen 12 Monate erfasst. 718 Pferde (24.7%) wurden im Erfassungszeitraum wegen 897 gesundheitlichen Problemen einem Tierarzt vorgestellt. Orthopädische und traumatische Fälle machten den grössten Anteil aus (41.5%), gefolgt von Erkrankungen des Gastrointestinal- (27.1%) und des Respirationstrakts (14.0%). Die Hälfte der Lahmheiten entstand als unmittelbare Folge einer Verletzung. Die Verletzungen waren assoziiert mit Weidegang/Auslauf (38.1%), Schläge/Bissen durch Artgenossen (21.6%), Stall (7.8%), Gelände (13.4%), Training (3.5%), Wettkampf (3.5%), Transport (3.0%) oder mit anderen Umständen (9.1%). In 26.5% der Kolikfälle wurde im Monat vor der Erkrankung Futterumstellung vorgenommen. Bei den Atmungserkrankungen wurde in 13.8% die gleiche Krankheit auch bei anderen Pferden im Stall diagnostiziert. Bei 8.1% aller Fälle erfolgte eine Operation, 6.7% waren mit einem mehrtägigem Klinikaufenthalt verbunden. Bei 25.6% aller tiermedizinisch diagnostizierten Fälle wurden ergänzend oder ausschliesslich komplementärmedizinische Therapiemethoden eingesetzt. | ||||

Title | Gibt es in der Gruppenhaltung von Pferden bei der Abruffütterung am Automaten mehr Auseinandersetzungen als bei der Fütterung in Fressständen?

Abstract | Das Droh- und Meideverhalten von 270 Pferden wurde im Fressbereich von 10 Offenlaufställen mit Fressständen und 11 Offenlaufställen mit computergesteuerten Abrufstationen anhand von visuellen kontinuierlichen Direktbeobachtungen erfasst. Diese erfolgten je Betrieb über einen 24-Stunden-Tag, der nach dem Tortenstückverfahren (6x4 Stunden) zusammengesetzt war. Insgesamt wurden 6297 agonistische Verhaltensweisen in, vor und hinter den Fütterungseinrichtungen registriert (Meiden 40,6 %, Verdrängen 12,8 %, Beißen/ Hinterhandschlag/ Angehen 12,7 % und Drohen/ Drohbeißen/ Hinterhanddrohen 33,9 %). In den Futterstationen wurden 22,5 % dieses Verhaltens beobachtet, vor und hinter den Futterstationen 77,5 %. Bei den Betrieben mit Fressständen fanden 31 % der agonistischen Verhaltensweisen in den Ständen statt, bei den Betrieben mit Abruffütterung 21 %. Der Einfl uss des einzelnen Betriebes (innerhalb Fütterungssystem) auf die agonistischen Verhaltensweisen vor und hinter den Fütterungseinrichtungen war signifi kant. Die Auswertung ergab, dass Drohgesten im Wartebereich von Abrufstationen häufi ger auftreten als in dem von Fressständen. Demgegenüber können Pferde in Abrufstationen ungestörter fressen. Insgesamt betrachtet war jedoch die Anzahl an sozionegativen Interaktionen im Bereich der Futtereinrichtungen bei beiden Fütterungssystemen gering. Die agonistischen Verhaltensweisen wurden zusätzlich noch von der Heumenge und dem Konstitutionstyp beeinfl usst. Der Betrieb erwies sich als maßgeblicher Einfl ussfaktor. Als Resümee ergibt sich, dass bei ordnungsgemäßer Gruppenhaltung mit fachgerechtem Management beide Fütterungssysteme für Pferde im Offenlaufstall geeignet sind. [The threatening and avoiding behaviour of 270 horses living in run-out sheds was observed at 10 stables with feeding stalls and at 11 stables with automatic feeding systems for hay and concentrates. Every group of horses was observed on five succeeding days visually and immediately for 6 sessions, each of 4 hours. These 6 slices form together 24 hours, a complete day. Altogether, 6297 agonistic behaviour patterns were registered in front of, inside and behind the feeding stations (avoiding behaviour 40.6 %, edging out of others 12.8 %, Auseinandersetzungen an automatischer Abruffütterung und Fressständen KTBL-Schrift 471 79 biting/rear leg kicking/charging 12.7 % und threatening/biting threats/rear leg kicking threats 33.9 %). 22.5 % of these types of behaviour were recorded in the feeding stations, 77.5 % together in front and behind of these. In the stables with feeding stalls there were 31 % of the observed threatening gestures inside the feeding stations, in the stables with automatic feeders only 21 %. The individual farm showed signifi cant infl uence on the modes of agonistic behaviour in front and behind the feeding facilities. Threatening gestures happen more often in the waiting area of automatic feeders than in that of feeding stalls. On the other hand horses in computer controlled systems will be less disturbed at eating. All together the number of negative interactions in the feeding area at both feeding systems was relatively low. In addition the agonistic behaviour was infl uenced by the quantity of hay and the constitutional typ of the horses. Because of the management of the individual stable exercises the most substantial infl uence on the behaviour of the horses, it can be said, that, correct group keeping with professional management provided, both feeding systems are suitable for horses in run-in sheds.] |

Title | Reciprocity of support in coatis (Nasua nasua) | Type | Journal Article | ||

Abstract | Primate sociality has received much attention and its complexity has been viewed as a driving force for the evolution of cognitive abilities. Improved analytic techniques have allowed primate researchers to reveal intricate social networks based on the exchange of cooperative acts and services. Although nonprimates are known to show similar behavior (e.g., cooperative hunting, food sharing, coalitions) there seems a consensus that social life is less complex than in primates. Here the authors present the first group-level analysis of reciprocity of social interactions in a social carnivore, the ring-tailed coati (<xh:i xmlns:search=“http://marklogic.com/appservices/search” xmlns=“http://apa.org/pimain” xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance” xmlns:xh=“http://www.w3.org/1999/xhtml”>Nasua nasua</xh:i>). The authors found that support in aggressive conflicts is a common feature in coatis and that this behavior is reciprocally exchanged in a manner seemingly as complex as in primates. Given that reciprocity correlations persisted after controlling for the effect of spatial association and subunit membership, some level of scorekeeping may be involved. Further studies will be needed to confirm our findings and understand the mechanisms underlying such reciprocity, but our results contribute to the body of work that has begun to challenge primate supremacy in social complexity and cognition.

Abstract | Fourteen dogs (7 males and 7 females) were tested for their heart rate (HR) and heart rate variability (HRV) responses in different activities and environmental challenges while their movement was controlled. First, we wanted to compare the dogs? cardiac responses in different body positions (lying, sitting and standing) and during slow walking to reveal their possible influence on HR and HRV. Second, we tested the HR response during an attentive state when the dog was gazing at its favourite toy while remaining in a steady body position. Finally we investigated the heart activity during separation from the owner. We also analysed the individual differences and the influence of gender on the heart responses. We found that the HR increased during periods of increased activity (walking) and was lowest during lying, while it did not differ between sitting and standing. At the same time no changes in HRV were found in the case of different body positions and walking. In contrast, HRV significantly increased when dogs oriented towards their favourite toy, and we found a distinct individual characteristic HR change in this situation compared to the similar body position without the toy being shown. Interestingly during separation from the owner the HR did not increase, but when a strange person was petting the dog, a significant increasing effect was seen in the HR. However the HRV increased only when the petting was discontinued. In general, large individual variation was found with regard to the HR and HRV, while gender did not influence the cardiac activity of the dogs.These results show that body position affected HR significantly in dogs. Further it seems that HRV could be a good indicator of the dog's attentive state. Thus in future studies both the physical and cognitive factors should be given more attention when HR or HRV is investigated as a dependent variable. | ||||

Title | Revisiting the definition of animal tool use | Type | Journal Article | ||
Year | 2008 | Publication | Animal Behaviour | Abbreviated Journal | Anim. Behav. |
Volume | 75 | Issue | 4 | Pages | 1199-1208 |
Keywords | cognition; tool use | ||||
Abstract | Benjamin Beck's definition of tool use has served the field of animal cognition well for over 25 years (Beck 1980, Animal Tool Behavior: the Use and Manufacture of Tools, New York, Garland STPM). This article proposes a new, more explanatory definition that accounts for tool use in terms of two complementary subcategories of behaviours: behaviours aimed at altering a target object by mechanical means and behaviours that mediate the flow of information between the tool user and the environment or other organisms in the environment. The conceptual foundation and implications of the new definition are contrasted with those of existing definitions, particularly Beck's. The new definition is informally evaluated with respect to a set of scenarios that highlights differences from Beck's definition as well as those of others in the literature. | ||||

Abstract | ABSTRACTAlthough most human-animal bond research has focused on relationships between humans and pets, animals have been used for therapeutic purposes in a variety of settings. Therapeutic riding programs have demonstrated a positive impact on quality of life for people with disabilities. Equine-facilitated psychotherapy is a promising approach to address self-esteem, depression, and other emotional or psychological problems. Restoration of the trauma victim's capacity for recovery hinges on provision of safety and development of trust, self-esteem, and self-efficacy. Thus, recovery from trauma represents an ideal context for exploring the therapeutic impact of equine?human relationships. The six participants in this study recognized that their pre-existing relationships with horses were therapeutic during recovering from trauma, defined as sufficient to have caused significant change in the participant's life. Semi-structured interviews and video-tapes of horse?rider interaction were used to describe the nature of the equine?human bond and its contribution to recovery from trauma. The equine?human bonds described by participants have parallels both with important elements of therapeutic alliances between professionals and clients and with the positive impact of relationship factors on client outcome. | ||||

Title | The origin and spread of innovations in starlings | Type | Journal Article | ||
Year | 2008 | Publication | Animal Behaviour | Abbreviated Journal | Anim. Behav. |

Abstract | There are numerous reports of novel learned behaviour patterns in animal populations, yet the factors influencing the invention and spread of these innovations remain poorly understood. Here we investigated to what extent the pattern of spread of innovations in captive groups of starlings, Sturnus vulgaris, could be predicted by knowledge of individual and social group variables, including association patterns, social rank orders, measures of neophobia and asocial learning performance. We presented small groups of starlings with a series of novel extractive foraging tasks and recorded the latency for each bird to contact and solve each task, as well as the orders of contacting and solving. We then explored which variables best predicted the observed diffusion patterns. Object neophobia and social rank measures characterized who was the first of the group to contact the novel foraging tasks, and the subsequent spread of contacting tasks was associated with latency to feed in a novel environment. Asocial learning performance, measured in isolation, predicted who was the first solver of the novel foraging tasks in each group. Association patterns did not predict the spread of solving. Contact latency and solving duration were negatively correlated, consistent with social learning underlying the spread of solving. Our findings indicate that we can improve our understanding of the diffusion dynamics of innovations in animal groups by investigating group-dependent and individual variables in combination. We introduce novel methods for exploring predictors of the origin and spread of behavioural innovations that could be widely applied. | ||||
