	Title	Behaviour of Bachelor Males of the Przewalski Horse (Equus ferus przewalskii) at the Reserve Askania Nova			Type	Journal Article
	Year	2009	Publication	Der Zoologische Garten	Abbreviated Journal	Zoologische Garten
	Volume	78	Issue	5-6	Pages	282-299
	Keywords	Equid; Przewalski horse (Equus ferus przewalskii); Bachelor group; Social behaviour
	Abstract	The aim of this study was to investigate social relationships between Przewalski horses at a high density in a bachelor group housed in a 3.5-ha enclosure. The group consisted of 16 males aged 5 to 16. Behavioural data were collected during 18 days, total 216 h. Fifteen minute focal animal sampling was used; each horse was observed three times a day for a total of 45 min. The occurrence of 25 behaviours was recorded, and group spacing behaviour was studied using nearest neighbour recordings. The group divided into four subgroups; this supports earlier findings of bachelor groups (n>=10) dividing into two or more subgroups if they included several males aged >5 years. The total frequency of social interactions was 14.6±1.1 h-1. Although the density of the group in this study was higher than in other zoos, the males interacted agonistically only 3.6 h-1. The most frequently observed social behaviour categories were friendly interactions. This study shows possibilities to use some investigative behaviours (marking, flehmen, olfactory investigation, etc.) as indicators of social status of animals in a group.

	Title	Abrufautomaten für Pferde im Offenlaufstall im Vergleich – Besuchshäufigkeit, Aufenthaltsdauer und Anzahl an Auseinandersetzungen [A comparison of automatic feeding systems for horses in run-out-sheds – frequency of visit, duration of stay and number of conflicts]			Type	Book Chapter
	Year	2009	Publication	KTBL-Schrift	Abbreviated Journal
	Volume	479	Issue		Pages
	Keywords
	Abstract	In 32 Offenlaufställen mit computergesteuerten Abrufstationen wurden die Aufenthaltsdauer und Besuchshäufigkeit sowie das Droh- und Meideverhalten von 439 Pferden im Füttererungsbereich erfasst. Je Betrieb erfolgten visuelle kontinuierliche Direktbeobachtungen nach dem Tortenstückverfahren (6 x 4 Stunden) für je einen 24-Stunden-Tag. Ziel war die Überprüfung der verschiedenen Bauausführungen der Abrufstationen unter dem Aspekt der Tiergerechtheit. Eine Einwegstation reduzierte signifikant die Anzahl an Auseinandersetzungen im Fütterungsbereich. Demgegenüber führten die für das fressende Pferd tiergerechten Varianten (Fressstand mit Eingangssperre und ohne Austreibehilfe) zu einer Erhöhung der Besuchshäufigkeit und Aufenthaltsdauer und somit auch zu einer erhöhten Anzahl an Drohgesten. Doch insgesamt betrachtet, kann die Anzahl an sozionegativen Interaktionen im Fütterungsbereich der Abrufstationen als relativ gering eingestuft werden. Da sich außerdem der Betrieb (Management, Fläche, Konzeption) als maßgeblicher Einflussfaktor auf die überprüften Parameter erwies, dürften die Unterschiede in der Bauausführung der derzeitigen Abrufstationen für Pferde eher von untergeordneter Bedeutung sein. [Duration of stay, frequency of visit, threatening gestures and behaviour of avoidance of 439 horses was observed at the feeding area of 32 run-out-sheds. The observation was based on the method of visual continuously direct watching after the pie chart system (6 x 4 hours) over a period of 24 hours. The observation should show which construction of the different automatic feeding systems corresponded best under the aspect of animal welfare. It was obvious that the one-way-station reduced significantly the number of conflicts in the feeding area, whereas those systems which are appropriate for the eating horses (feeding station with access barrier and without stimulation device by electric shock) led to a higher frequency of visits and duration of stay as well as to more threatening gestures. Considering altogether, the number of negative interactions in the feeding area of the feeding systems can be classified as comparatively unimportant. As it showed that the stable (management, stable area, conception) was of important influence on the surveyed parameters, the differences between the constructions of feeding stations for horses of present systems are probably of less meaning.]

	Title	SOCPROG programs: analysing animal social structures			Type	Journal Article
	Year	2009	Publication	Behavioral Ecology and Sociobiology	Abbreviated Journal	Behav. Ecol. Sociobiol.
	Volume	63	Issue	5	Pages	765-778
	Keywords	Social analysis – Software – Association
	Abstract	Abstract SOCPROG is a set of programs which analyses data on animal associations. Data usually come from observations of the social behaviour of individually identifiable animals. Associations among animals, sampling periods, restrictions on the data and association indices can be defined very flexibly. SOCPROG can analyse data sets including 1,000 or more individuals. Association matrices are displayed using sociograms, principal coordinates analysis, multidimensional scaling and cluster analyses. Permutation tests, Mantel and related tests and matrix correlation methods examine hypotheses about preferred associations among individuals and classes of individual. Weighted network statistics are calculated and can be tested against null hypotheses. Temporal analyses include displays of lagged association rates (rates of reassociation following an association). Models can be fitted to lagged association rates. Multiple association measures, including measures produced by other programs such as genetic or range use data, may be analysed using Mantel tests and principal components analysis. SOCPROG also performs mark-recapture population analyses and movement analyses. SOCPROG is written in the programming language MATLAB and may be downloaded free from the World Wide Web.

	Title	Trainability of eliminative behaviour in dairy heifers using a secondary reinforcer			Type	Journal Article
	Year	2009	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	117	Issue	3-4	Pages	128-136
	Keywords	Cattle; Eliminative behaviour; Learning; Clicker training; Clean bedding
	Abstract	Soiled bedding influences cleanliness and disease levels in dairy cows and there is no evidence of an inherent latrine behaviour in cattle. If cows were trained to use a concrete area of the housing system as a latrine, a cleaner bed could be maintained. Thirteen group-housed, 14-16-month-old Holstein-Friesian heifers, were clicker trained with heifer-rearing concentrate pellets as a reward. Training was carried out in four phases. (Phase 1) Association of feed reward with clicker, criterion: 34/40 correct responses. (Phase 2) Simple task (nose-butting a disc) to reinforce phase 1 association, criterion: 17/20 correct responses. (Phase 3) Association of eliminative behaviour with reward where criterion was four sessions with only one incorrect response: criteria for each heifer in phases 1-3 were set using binomial tests. (Phase 4) Shaping eliminative behaviour to occur on concrete. Possible responses were, eliminating on concrete (C) or straw (S), or moving from one substrate to another immediately before eliminating: CÂ -->Â S, SÂ -->Â C. Heifers were rewarded for the desired behaviours C and SÂ -->Â C and ignored when S and CÂ -->Â S occurred. If learning was achieved, C should increase as CÂ -->Â S decreased and SÂ -->Â C should increase as S decreased: tested with Spearman rank correlations. All heifers achieved criterion by day 4 of phase 1 (PÂ =Â 0.001); day 1 of phase 2 (PÂ =Â 0.001) and day 10 of phase 3 (PÂ <Â 0.009). Responses changed throughout phase 3 beginning with (i) looking at the trainer whilst voiding then moving to trainer after the click, and later including (ii) moving to trainer immediately before- or (iii) during voiding. No relationship was found between S and SÂ -->Â C (rsÂ =Â -0.14; PÂ =Â 0.63) or C and CÂ -->Â S (rsÂ =Â -0.33; PÂ =Â 0.25). All group members eliminated more often on concrete (580) than on straw (141) but four heifers with consistently longer lying bouts also showed more CÂ -->Â S before lying down (Mann-Whitney, PÂ =Â 0.007). The present study is believed to be the first reported work to show that cattle can be trained to show an awareness of their own eliminative behaviour. This was not successfully shaped to latrine behaviour, however, and it is suggested that floor type may not have been a sufficiently salient cue. Voiding on straw occurred largely with response CÂ -->Â S (0.73) and general behaviour suggested that this was strongly linked to lying patterns of individual heifers.

	Title	Hind limb stepping over obstacles in the horse guided by place-object memory			Type	Journal Article
	Year	2009	Publication	Behavioural Brain Research	Abbreviated Journal	Behav. Brain. Res.
	Volume	198	Issue	2	Pages	372-379
	Keywords	Horse place memory; Memory and hind limb stepping; Obstacle memory in horse; Obstacle stepping in horse; Place memory for stepping; Stepping in the horse; Working memory for stepping
	Abstract	An animal that has stepped over an obstacle with its forelimbs uses a memory of the obstacle to guide the hind limbs so that they also clear the obstacle, even in situations in which long pauses are introduced between forelimb and hind limb stepping. To further clarify the features of hind limb obstacle clearance memory, the present study examined hind limb obstacle clearance in the horse. A rider guided horses over obstacles and paused the horse over obstacles in tests that examined the relationship between forelimb and hind limb stepping, with the following results. First, the horses displayed memory for an obstacle as measured by hind limb lifting over the obstacle for durations lasting as long as 15Â min. The response was not dependent upon ongoing visualization of the obstacle, as limb lifting was unaffected by visual occlusion with blinders, a blindfold, or by removing the obstacle during the pause. Second, previous experience of stepping over an obstacle led to pause-related hind limb lifting at the object's previous location even on trials for which there was no obstacle and so no preceding forelimb lifting. Third, whereas a horse would lift its hind limbs to clear two successively presented obstacles, replacing an obstacle before the horse after the forelimbs had cleared the obstacle prevented subsequent hind limb lifting at the obstacle's previous location. Taken together the results show that hind limb obstacle clearance is guided by a place-object memory. The results are discussed in relation to the differential sensory and memonic control of forelimb and hind limb stepping with the suggestion that place-object memory can guide hind stepping as well as overshadow working memory from front leg stepping.

	Title	Lateralized behaviour in the domestic cat, Felis silvestris catus			Type	Journal Article
	Year	2009	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	78	Issue	2	Pages	537-541
	Keywords	cat; Felis silvestris catus; handedness; laterality; paw preference
	Abstract	Lateralized behaviour in the felids has been subject to little investigation. We examined the paw use of 42 domestic cats on three tasks designed to determine whether the animals performed asymmetrical motor behaviour. The influence of the cats' sex and age on their paw preferences was also explored. The distribution of the cats' paw preferences differed significantly between the three tasks. Task 1, the most complex exercise involving retrieval of a food treat from an empty jar, encouraged the most apparent display of lateralized behaviour, with all but one animal showing a strong preference to use either their left or right paw consistently. Tasks 2 (an exercise involving reaching for a toy suspended overhead) and 3 (a challenge involving reaching for a toy moving along the ground) encouraged ambilateral motor performance. Lateralized behaviour was strongly sex related. Male and female cats showed paw preferences at the level of the population, but in opposite directions. Females had a greater preference for using their right paw; males were more inclined to adopt their left paw. Feline age was unrelated to either strength or direction of preferred paw use. Overall, the findings suggest that there are two distinct populations of paw preference in the cat that cluster strongly around the animals' sex. The results also point to a relationship between lateralized behaviour and task complexity. More apparent patterns of lateralized behaviour were evident on more complex manipulatory tasks, hinting at functional brain specialization in this species.

	Title	Varieties of altruism in children and chimpanzees			Type	Abstract
	Year	2009	Publication	Trends in cognitive sciences	Abbreviated Journal	Trends Cogn Sci
	Volume	13	Issue	9	Pages	397-402
	Keywords
	Abstract	Recent empirical research has shed new light on the perennial question of human altruism. A number of recent studies suggest that from very early in ontogeny young children have a biological predisposition to help others achieve their goals, to share resources with others and to inform others of things helpfully. Humans nearest primate relatives, such as chimpanzees, engage in some but not all of these behaviors: they help others instrumentally, but they are not so inclined to share resources altruistically and they do not inform others of things helpfully. The evolutionary roots of human altruism thus appear to be much more complex than previously supposed.

	Title	Third-party interventions in dyadic play between littermates of domestic dogs, Canis lupus familiaris			Type	Journal Article
	Year	2009	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	78	Issue	5	Pages	1153-1160
	Keywords	Canis lupus familiaris; domestic dog; littermates; play; social development; third-party interventions
	Abstract	Interventions occur when animals interfere in competitive interactions between two or more individuals. Interveners can alter the nature of the ongoing interaction by targeting one party (attacking, biting) and supporting the other. Three theories have been proposed to account for intervention behaviour: kin selection, reciprocity and direct benefits. The kin selection hypothesis predicts that interveners will selectively support relatives over nonrelatives; the reciprocity hypothesis predicts that when intervener [`]A' supports individual [`]B', later [`]B' will intervene and support [`]A'; and the direct benefits hypothesis predicts that target/support patterns should serve the immediate interests of the intervener. We tested the reciprocity and direct benefits hypotheses by exploring third-party interventions in play fighting among littermates of domestic dogs. Interveners in dyadic play did not preferentially target or support preferred playmates of the intervener. Interveners targeted the dog in the losing role at the time of the intervention, and they did not show reciprocity in support. Taken together, these last two findings suggest that littermates benefit directly and use interventions opportunistically to practise offence behaviours directed at littermates already behaving subordinately. Opportunities to practise targeting in a playful setting may help structure dominance relationships among littermates. Additionally, the tendency for puppies to do what the other is doing (target the dog in the losing role) may pave the way for synchronizing cooperative behaviours during group hunting and territorial defence. The types of behaviours used to intervene changed over development, but the outcome following an intervention remained stable.

	Title	Relationship between the forces acting on the horse's back and the movements of rider and horse while walking on a treadmill			Type	Journal Article
	Year	2009	Publication	Equine Veterinary Journal	Abbreviated Journal
	Volume	41	Issue	3	Pages	285-291
	Keywords	horse; ground reaction forces; kinematics; rider; saddle force
	Abstract	Reasons for performing study: The exact relationship between the saddle pressure pattern during one stride cycle and the movements of horse and rider at the walk are poorly understood and have never been investigated in detail. Hypothesis: The movements of rider and horse account for the force distribution pattern under the saddle. Method: Vertical ground reaction forces (GRF), kinematics of horse and rider as well as saddle forces (FS) were measured synchronously in 7 high level dressage horses while being ridden on an instrumented treadmill at walk. Discrete values of the total saddle forces (FStot) were determined for each stride and related to kinematics and GRF. The pressure sensitive mat was divided into halves and sixths to assess the force distribution over the horse's back in more detail. Differences were tested using a one sample t test (P<0.05). Results: FStot of all the horses showed 3 peaks (P1-P3) and 3 minima (M1-M3) in each half-cycle, which were systematically related to the footfall sequence of the walk. Looking at the halves of the mat, force curves were 50% phase-shifted. The analysis of the FS of the 6 sections showed a clear association to the rider's and horse's movements. Conclusion: The saddle force distribution during an entire stride cycle has a distinct pattern although the force fluctuations of the FStot are small. The forces in the front thirds were clearly related to the movement of the front limbs, those in the mid part to the lateral flexion of the horse's spine and the loading of the hind part was mainly influenced by the axial rotation and lateral bending of the back. Potential relevance: These data can be used as a reference for comparing different types of saddle fit.
