  Title Approach and follow behaviour – possible indicators of the human-horse relationship Type Abstract
  Year 2010 Publication Interaction Studies Abbreviated Journal  
  Volume 11 Issue 3 Pages 410-427  
  Keywords Approach; Follow; Human– Horse Interaction  
  Abstract The aim of our study was to analyze the behavioural responses of horses (N = 51) to familiar humans and to find factors that may affect these responses in three tests: (1) approach to, (2) standing beside, and (3) following the familiar person. We investigated the impacts of horse-related factors (gender and age) and human-related factors (type of work, housing management, amount of handling, number of handlers and training to follow).<br xmlns=“http://pub2web.metastore.ingenta.com/ns/”></br> Horses with one handler needed less time to approach the human than horses with more handlers. Standing beside the human correlated positively with following. Following was mainly affected by training.<br xmlns=“http://pub2web.metastore.ingenta.com/ns/”></br> According to our results, the number of handlers has an important effect on horses' responses to familiar humans, especially regarding approach and follow behaviour. However, following behaviour is fundamentally determined by training.

  Title Automatic feeding systems for horses in group housing systems with regard to animal welfare. Part 1: Feeding stalls versus automatic feeding systems Type Journal Article
  Year 2010 Publication Tierärztliche Praxis Großtiere Abbreviated Journal Tierärztl Prax  
  Volume 38 Issue G Pages 363-370  
  Keywords Pferd, Fütterungseinrichtungen, soziale Interaktionen, Herzfrequenz, Verletzungsrisiko, Betriebseinfluss [Horse, feeding stations, social interactions, heart rate, risk of injury, individual farm management]  
  Abstract Gegenstand und Ziel: Überprüfung der Tiergerechtheit von Abrufstationen

für Kraftfutter und Heu in der Gruppenhaltung von Pferden anhand

ethologischer und physiologischer Parameter im Vergleich zu konventionellen

Fressständen. Material und Methoden: Die Verhaltensbeobachtungen

fanden in 11 bzw. 10 Offenlaufställen mit Abrufstationen

bzw. Fressständen statt. 270 Pferde wurden individuell unterschieden.

Untersuchungsparameter waren: Drohverhalten mit und ohne Verletzungsrisiko,

Meideverhalten, Verdrängung aus dem Fressstand sowie

Herzfrequenz und Integumentverletzungen. In jedem Betrieb erfolgten

kontinuierliche Direktbeobachtungen für je einen 24-Stunden-Tag (Tortenstückverfahren).

Ergebnisse: Im Wartebereich der Abrufautomaten

traten signifikant mehr Drohgesten ohne bzw. mit Verletzungsgefahr je

Pferd und Tag (8,6 bzw. 3,0) auf als im Wartebereich der Fressstände

(3,4 bzw. 0,9). Demgegenüber konnten die Pferde in Abrufstationen

(1,4 Drohgesten je Pferd und Tag) ungestörter fressen als in Fressständen

(3,2 Drohgesten je Pferd und Tag). Insgesamt betrachtet ergab sich

jedoch bei beiden Fütterungssystemen eine geringe Anzahl an sozionegativen

Interaktionen im Bereich der Futtereinrichtungen. Die Herzfrequenz

lag im Warteareal im Durchschnitt im physiologischen Bereich

(44,59 ± 11,73 Schläge/min). Integumentverletzungen im Zusammenhang

mit dem Fütterungssystem traten nicht auf. Der wichtigste Einflussfaktor

auf die Untersuchungskriterien war der Betrieb (Fläche, Konzeption,

Management). Schlussfolgerung: Unter dem Aspekt der Tiergerechtheit

hinsichtlich des Stress- und Verletzungsrisikos durch soziale

Interaktionen eignen sich bei ordnungsgemäßer Gruppenhaltung mit

fachgerechtem Management sowohl Fressstände als auch Abrufstationen

für Pferde im Offenlaufstall.

[Objective: A comparison with regard to animal welfare of feeding

stalls and automatic feeding systems for hay and concentrates in group

housing systems for horses using parameters of ethology and physiology.

Material and method: The observations of animal behaviour took

place in 10 stables with feeding stalls and in 11 stables with automatic

feeding systems. The field around the feeding systems was divided into

three areas with comparable dimensions (waiting area, exit area and

inside of the feeding system). 270 horses were individually observed.

Parameters of research comprised: threatening behaviour with and

without risk of injury, avoiding behaviour, ”chasing away from the feeding

place”, as well as heart rate and injuries of the integument. Every

group of horses was continuously observed for 24 hours. This observation

took place on four different days and comprised six sessions, each

of 4 hours. Results: In the waiting area of the automatic systems there

were significantly more threatening gestures with and without risk of

injuries for each horse and day (8.6 and 3.0, respectively) than in the

waiting area of the feeding stalls. In contrast, the horses could eat more

relaxed in the automatic systems (1.4 threatening gestures for each

horse and day) than in the feeding stalls (3.2 threatening gestures for

each horse and day). All together the number of negative interactions in

the feeding area of both feeding systems was relatively low. The heart

rate was within the physiological range (44,59 ± 11,73 beats/min) in

the waiting area. There were no injuries of the integument in correlation

with the feeding systems. The most important factor of the observation

criteria was the individual group housing system with its different dimension,

conception and management. Conclusion: Under the aspect

of animal welfare both feeding systems are suitable for horses with respect

to the risk of stress and injuries by social interactions and under

the condition of proper group housing with professional management.]

  Title Catecholamine plasma levels following immune stimulation with rabies vaccine in dogs selected for their paw preferences Type Journal Article
  Year 2010 Publication Neuroscience Letters Abbreviated Journal  
  Volume 476 Issue 3 Pages 142-145  
  Keywords Physiology; Behavior; Lateralization; Catecholamines; Paw preference; Neuro-immune-modulation  
  Abstract Epinephrine and norepinephrine plasma levels were assessed in dogs in relation to paw preference following an immune challenge with rabies vaccine. The results showed that both catecholamines increased after the vaccine administration, confirming the main role of the sympathetic nervous system in the modulation activity between the brain and the immune system. Moreover, ambidextrous dogs showed a significantly higher increase of epinephrine levels 8 days after immunization with respect to right- and left-pawed dogs, suggesting that the biological activity of this molecule could be key for a different immune response with regard to laterality.

  Title Social Bonds Enhance Reproductive Success in Male Macaques Type Journal Article
  Year 2010 Publication Current Biology Abbreviated Journal Curr. Biol.  
  Volume 20 Issue 24 Pages 2207-2210  
  Keywords  
  Abstract Summary For animals living in mixed-sex social groups, females who form strong social bonds with other females live longer and have higher offspring survival [1–3]. These bonds are highly nepotistic, but sometimes strong bonds may also occur between unrelated females if kin are rare [2, 3] and even among postdispersal unrelated females in chimpanzees and horses [4, 5]. Because of fundamental differences between the resources that limit reproductive success in females (food and safety) and males (fertilizations), it has been predicted that bonding among males should be rare and found only for kin and among philopatric males [6] like chimpanzees [7–9]. We studied social bonds among dispersing male Assamese macaques (Macaca assamensis) to see whether males in multimale groups form differentiated social bonds and whether and how males derive fitness benefits from close bonds. We found that strong bonds were linked to coalition formation, which in turn predicted future social dominance, which influenced paternity success. The strength of males' social bonds was directly linked to the number of offspring they sired. Our results show that differentiated social relationships exert an important influence on the breeding success of both sexes that transcends contrasts in relatedness.

  Title Close social associations in animals and humans: functions and mechanisms of friendship Type
  Year 2010 Publication Behaviour Abbreviated Journal  
  Volume 147 Issue 11 Pages 1379  
  Keywords Both humans and group-living animals associate and behave affiliatively more with some individuals than others. Human friendship has long been acknowledged, and recently scientists studying animal behaviour have started using the term friendship for close social associates in animals. Yet, while biologists describe friends as social tools to enhance fitness, social scientists describe human friendship as unconditional. We investigate whether these different descriptions reflect true differences in human friendship and animal close social associations or are a by-product of different research approaches: namely social scientists focussing on proximate and biologists on ultimate explanations. We first stress the importance of similar measures to determine close social associations, thereafter examine their ultimate benefits and proximate motivations, and discuss the latest findings on the central-neural regulation of social bonds. We conclude that both human friendship and animal close social associations are ultimately beneficial. On the proximate level, motivations for friendship in humans and for close social associations in animals are not necessarily based on benefits and are often unconditional. Moreover, humans share with many animals a similar physiological basis of sociality. Therefore, biologists and social scientist describe the same phenomenon, and the use of the term friendship for animals seems justified.

  Title Relationship between saddle pressure measurements and clinical signs of saddle soreness at the withers Type Journal Article
  Year 2010 Publication Equine Veterinary Journal Abbreviated Journal  
  Volume 42 Issue Pages 650-653  
  Keywords horse; saddle sore; saddle pressure measurement; dry spots  
  Abstract Reasons for performing the study: Similar to human decubitus ulcers, local high pressure points from ill-fitting saddles induce perfusion disturbances of different degrees resulting in tissue hypoxia and alteration in sweat production. Objective: To relate the different clinical manifestations of saddle sores to the magnitude of saddle pressures at the location of the withers. Methods: Sixteen horses with dry spots after exercise (Group A) and 7 cases presented with acute clinical signs of saddle pressure in the withers area (Group B) were compared with a control group of 16 sound horses with well fitting saddles (Group C). All horses underwent a saddle pressure measurement at walk, trot and canter. Mean and maximal pressures in the area of interest were compared between groups within each gait. Results: Mean pressures differed significantly between groups in all 3 gaits. Maximal pressure differed between groups at trot; at walk and canter, however, the only significant difference was between Group C and Groups A and B, respectively, (P>0.05). Mean and maximal pressures at walk in Group A were 15.3 and 30.6 kPa, in Group B 24.0 and 38.9 kPa and in Group C 7.8 and 13.4 kPa, respectively; at trot in Group A 18.1 and 43.4 kPa, in Group B 29.7 and 53.3 kPa and in Group C 9.8 and 21.0 kPa, respectively; and at canter in Group A 21.4 and 48.9 kPa, in Group B 28.6 and 56.0 kPa and in Group C 10.9 and 24.7 kPa, respectively. Conclusion: The study shows that there is a distinguishable difference between the 3 groups regarding the mean pressure value, in all gaits.

  Title Inter-individual and age differences in exploration, neophobia and problem-solving ability in a Neotropical raptor (Milvago chimango) Type Journal Article
  Year 2010 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume 13 Issue 5 Pages 701-710  
  Keywords  
  Abstract Animal innovations have far-reaching ecological and evolutionary consequences. The occurrence and persistence of an innovation require several processes, including exploration, social and asocial learning, and low neophobia. In addition, the identity of the innovator may determine how these new behaviours are socially transmitted. Taking into account inter-individual and age differences, we investigated three correlates of animal innovation: object exploration, neophobia level and novel problem-solving ability in an opportunistic generalist raptor, the Chimango Caracara (Milvago chimango). Eighteen individuals (7 adults and 11 juveniles) were caught during the non-breeding period and housed in individual cages in outdoor aviaries. Each bird was given three tests: exploration, neophobia and problem-solving. Individuals differed in their response to novel situations both within and between age groups. Most of the juveniles were more explorative and had a lower neophobic response to a strange object than adult birds, but both age groups were able to solve a novel problem when given a food reward. In juveniles, neophobia level and problem-solving performance were inversely related; however, we found no relationship between these behaviours in adults. Exploration did not correlate with neophobia or problem-solving ability for either age group. This research is one of the few studies exploring the inter-individual and age differences in behavioural innovation and their correlates in a bird of prey. The explorative tendency, low neophobia and ability to innovate showed by M. chimango may be advantageous for this generalist and opportunistic raptor and might be some of the factors underlying its ecological success.

  Title Choosing an appropriate index to construct dominance hierarchies in animal societies: a comparison of three indices Type Journal Article
  Year 2010 Publication Animal Behaviour Abbreviated Journal  
  Volume 79 Issue 3 Pages 631-636  
  Keywords dominance behaviour; dominance hierarchy; dominance index; dominance rank; Ropalidia cyathiformis; Ropalidia marginata; social wasp  
  Abstract A plethora of indices have been proposed and used to construct dominance hierarchies in a variety of vertebrate and invertebrate societies, although the rationale for choosing a particular index for a particular species is seldom explained. In this study, we analysed and compared three such indices, viz Clutton-Brock et al.'s index (CBI), originally developed for red deer, Cervus elaphus, David's score (DS) originally proposed by the statistician H. A. David and the frequency-based index of dominance (FDI) developed and routinely used by our group for the primitively eusocial wasps Ropalidia marginata and Ropalidia cyathiformis. Dominance ranks attributed by all three indices were strongly and positively correlated for both natural data sets from the wasp colonies and for artificial data sets generated for the purpose. However, the indices differed in their ability to yield unique (untied) ranks in the natural data sets. This appears to be caused by the presence of noninteracting individuals and reversals in the direction of dominance in some of the pairs in the natural data sets. This was confirmed by creating additional artificial data sets with noninteracting individuals and with reversals. Based on the criterion of yielding the largest proportion of unique ranks, we found that FDI is best suited for societies such as the wasps belonging to Ropalidia, DS is best suited for societies with reversals and CBI remains a suitable index for societies such as red deer in which multiple interactions are uncommon.

  Title A comparison of bonobo and chimpanzee tool use: evidence for a female bias in the Pan lineage Type Journal Article
  Year 2010 Publication Animal Behaviour Abbreviated Journal Anim. Behav.  
  Volume 80 Issue 6 Pages 1023-1033  
  Keywords culture; great ape; neoteny; Pan; primate evolution; sex difference; tool use  
  Abstract Chimpanzees, Pan troglodytes, are the most sophisticated tool-users among all nonhuman primates. From an evolutionary perspective, it is therefore puzzling that the tool use behaviour of their closest living primate relative, the bonobo, Pan paniscus, has been described as particularly poor. However, only a small number of bonobo groups have been studied in the wild and only over comparably short periods. Here, we show that captive bonobos and chimpanzees are equally diverse tool-users in most contexts. Our observations illustrate that tool use in bonobos can be highly complex and no different from what has been described for chimpanzees. The only major difference in the chimpanzee and bonobo data was that bonobos of all age–sex classes used tools in a play context, a possible manifestation of their neotenous nature. We also found that female bonobos displayed a larger range of tool use behaviours than males, a pattern previously described for chimpanzees but not for other great apes. Our results are consistent with the hypothesis that the female-biased tool use evolved prior to the split between bonobos and chimpanzees.

  Title Towards a bottom-up perspective on animal and human cognition Type Journal Article
  Year 2010 Publication Trends in Cognitive Sciences Abbreviated Journal Trends Cognit. Sci.  
  Volume 14 Issue 5 Pages 201-207  
  Keywords  
  Abstract Over the last few decades, comparative cognitive research has focused on the pinnacles of mental evolution, asking all-or-nothing questions such as which animals (if any) possess a theory of mind, culture, linguistic abilities, future planning, and so on. Research programs adopting this top-down perspective have often pitted one taxon against another, resulting in sharp dividing lines. Insight into the underlying mechanisms has lagged behind. A dramatic change in focus now seems to be under way, however, with increased appreciation that the basic building blocks of cognition might be shared across a wide range of species. We argue that this bottom-up perspective, which focuses on the constituent capacities underlying larger cognitive phenomena, is more in line with both neuroscience and evolutionary biology.
