  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  
  Volume 34 Issue 6 Pages 1406-1415  
  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? [Keeping horses in groups, are there more confrontations when feeding is done with automatic feeding systems than with feeding stalls?] Type Book Chapter
  Year 2008 Publication KTBL-Schriften Abbreviated Journal  
  Volume 471 Issue Pages  
  Keywords  
  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
  Year 2008 Publication Journal of Comparative Psychology Abbreviated Journal  
  Volume 122 Issue 1 Pages 19-25  
  Keywords *Animal Aggressive Behavior; *Animal Social Behavior; *Mammals; Reciprocity  
  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.

  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.

  Title The origin and spread of innovations in starlings Type Journal Article
  Year 2008 Publication Animal Behaviour Abbreviated Journal Anim. Behav.  
  Volume 75 Issue 4 Pages 1509-1518  
  Keywords diffusion dynamics; dominance; foraging; group; innovation; neophobia; social learning; social network; starling; Sturnus vulgaris  
  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.

  Title Directed movement and orientation across a large natural landscape by zebras, Equus burchelli antiquorum Type Journal Article
  Year 2008 Publication Animal Behaviour Abbreviated Journal Anim. Behav.  
  Volume 76 Issue 2 Pages 277-285  
  Keywords correlated random walk; directed movement; Equus burchelli antiquorum; Gps; movement path; orientation; spatial memory; spatial scale; zebra  
  Abstract We investigated how plains zebras moved across a large natural landscape by analysing the movement paths of nine zebra mares foraging out from spatially confined waterholes during the dry season in the Makgadikgadi Pans National Park, Botswana. Since it was essential to investigate directed movement over a range of spatial scales to determine the correct movement behaviour and strategy, we used Nams's scaling test for oriented movement. Zebras followed directed movement paths in the lower to medium spatial scales (10 m–3.7 km) and above their visual, and possibly olfactory, range. The spatial scale of directed movement suggests that zebras had a well-defined spatial awareness and cognitive ability. Seven zebras used directed movement paths, but the remaining two followed paths not significantly different to a correlated random walk (CRW). At large spatial scales (>3 km) no distinct movement pattern could be identified and paths could not be distinguished from a CRW. Foraging strategy affected the extent of directed movement: zebras with a confined dispersion of grazing patches around the central place directed their movements over a longer distance. Zebras may extend the distance at which they can direct their movement after improving their knowledge of the local environment.

  Title Social learning strategies and predation risk: minnows copy only when using private information would be costly Type Journal Article
  Year 2008 Publication Proc Biol Sci Abbreviated Journal Proc. R. Soc. Lond. B  
  Volume 275 Issue 1653 Pages 2869-2876  
  Keywords  
  Abstract Animals can acquire information from the environment privately, by sampling it directly, or socially, through learning from others. Generally, private information is more accurate, but expensive to acquire, while social information is cheaper but less reliable. Accordingly, the 'costly information hypothesis' predicts that individuals will use private information when the costs associated with doing so are low, but that they should increasingly use social information as the costs of using private information rise. While consistent with considerable data, this theory has yet to be directly tested in a satisfactory manner. We tested this hypothesis by giving minnows (Phoxinus phoxinus) a choice between socially demonstrated and non-demonstrated prey patches under conditions of low, indirect and high simulated predation risk. Subjects had no experience (experiment 1) or prior private information that conflicted with the social information provided by the demonstrators (experiment 2). In both experiments, subjects spent more time in the demonstrated patch than in the non-demonstrated patch, and in experiment 1 made fewer switches between patches, when risk was high compared with when it was low. These findings are consistent with the predictions of the costly information hypothesis, and imply that minnows adopt a 'copy-when-asocial-learning-is-costly' learning strategy.
