Title Movements of Trunk and Back of the Horse from a Rider's View Type Journal Article
Year 2004 Publication Tierärztliche Umschau Abbreviated Journal Tierärztl. Umschau
Volume 6 Issue Pages 327
Keywords walk – trot – canter – pain – damages
Abstract The trunk and back movements of the horse during locomotion determine seat position and leg aids of the rider, this is the basis for horse-oriented and cultivated, sensitive riding. In their tendency these movements could now be derived from the foot sequences of the basic paces. The realizations are verified by video. By translating these movements into diagrams, the author is making an attempt to present the current state of knowledge for non-riding scholars and academically oriented riders alike. The acceptance of the prepared riding knowledge would be improved if one could produce measured values of the horse's back and trunk movements. An appeal of a rider for relevant, scholarly research.

Title The construction of dominance order: comparing performance of five methods using an individual-based model Type Journal Article
Year 2005 Publication Behaviour Abbreviated Journal Behaviour
Volume 142 Issue 8 Pages 1043-1064
Keywords dominance order, ranking method, agent-based model, statistical method, aggression
Abstract In studies of animal behaviour investigators correlate dominance with all kinds of behavioural

variables, such as reproductive success and foraging success. Many methods are used to

produce a dominance hierarchy from a matrix reflecting the frequency of winning dominance

interactions. These different methods produce different hierarchies. However, it is difficult to

decide which ranking method is best. In this paper, we offer a new procedure for this decision:

we use an individual-based model, called DomWorld, as a test-environment. We choose this

model, because it provides access to both the internal dominance values of artificial agents

(which reflects their fighting power) and the matrix of winning and losing among them and,

in addition, because its behavioural rules are biologically inspired and its group-level patterns

resemble those of real primates. We compare statistically the dominance hierarchy based on

the internal dominance values of the artificial agents with the dominance hierarchy produced

by ranking individuals by (a) their total frequency of winning, (b) their average dominance

index, (c) a refined dominance index, the David`s score, (d) the number of subordinates each

individual has and (e) a ranking method based on maximizing the linear order of the hierarchy.

Because dominance hierarchies may differ depending on group size, type of society, and the

interval of study, we compare these ranking methods for these conditions.We study complete

samples as well as samples randomly chosen to resemble the limitations of observing real

animals. It appears that two methods of medium complexity (the average dominance index

and David`s score) lead to hierarchical orders that come closest to the hierarchy based on

internal dominance values of the agents. We advocate usage of the average dominance index,

because of its computational simplicity.

Title Effects of observational learning on acquisition of an operant response in horses Type Journal Article
Year 1999 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 61 Issue 3 Pages 187-199
Keywords Horse; Observational learning; Stereotyped behaviour; Operant behaviour; Breed influence; Age influence
Abstract The effect of observational learning on the acquisition of an operant response was examined in eighteen riding horses and ponies. The test horses were randomly divided into three groups of six and individually exposed to one of three treatments. An additional horse was trained as a demonstrator, to perform the operant response. The observer horses watched either the demonstrator performing the bin-opening response (Group D+B); the demonstrator standing passively (Group D); or the operant bin in the absence of the demonstrator (Group B). Observers had access to and were free to interact with an identical bin during testing. Observers in Groups D+B and D were socially familiar with the demonstrator. Each test horse was tested once a day for 10 days. An ANOVA revealed no significant differences between treatment groups in the number of responses or the time taken to reach the learning criterion. However, there were highly significant differences between breed types, with non-warmbloods performing more bouts of opening the bin and feeding (p=0.02), feeding from the bin sooner (p=0.01) and reaching the criterion for learning sooner than warmbloods (p=0.05). There was also a significant negative linear relationship between horses' ages and time spent investigating the bin, with younger horses performing more investigative behaviour (y=-3.08x+106.86; p=0.02).

Title Effects of neonatal handling on subsequent manageability, reactivity and learning ability of foals Type Journal Article
Year 2005 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 92 Issue 1-2 Pages 143-158
Keywords Horse; Neonatal handling; Manageability; Emotional reactivity; Learning-ability; Human-animal relationship
Abstract Behaviour is an important factor to be taken into account in the various uses of horses. Today horses are mainly used for sport and leisure activities. They should therefore be easy to manage, calm and not fearful. Early handling is known to improve manageability and learning ability and to reduce fearfulness in various species. It has become fashionable in the horse industry to use an early training procedure, referred to as “imprint training”, which is said to produce durable if not permanent effects. However, no studies concerning the long-term effects of such neonatal handling have been carried out in horses. The present study examines the short- and long-term effects of neonatal handling on manageability, general reactivity and learning ability of foals. Twenty-six Welsh foals were studied: 13 were handled daily for 14 days from birth and 13 were non-handled controls. The handling procedure consisted of fitting a halter, gently patting all parts of each foal's body, picking up feet and leading over 40 m. Two days, 3 months, 6 months and 1 year after the end of the handling period, foals underwent behavioural tests to measure their manageability and various aspects of their reactivity. The results showed that neonatal handling has only short-term effects on manageability: 2 days after the handling period, handled animals were significantly easier to handle than controls for the four parameters measured during this test (time to fit a halter, time to pick up feet, walk ratio that is time during which foal walks under constraint/total time measured during leading and number of defensive reactions). Two parameters (time to fit a halter and walk ratio) were still lower in handled foals than in non-handled foals 3 months later and only one 6 months later (walk ratio). One year later there was no difference between groups. In addition, there was no effect of handling on reactivity at any time of testing or in any of the tests (reaction to isolation from conspecifics, presence of a human, presence of a novel object and to a surprise effect). Finally, neonatal handling did not improve the spatial or discriminative learning abilities measured at 14 months of age. To conclude, the effects of neonatal handling are only temporary.

Title Effects of handling at weaning on manageability and reactivity of foals Type Journal Article
Year 2004 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 87 Issue 1-2 Pages 131-149
Keywords Horse; Handling; Weaning; Manageability; Emotional reactivity; Fearfulness; Human-animal relationship
Abstract The horse's temperament, including its manageability and reactivity and/or fearfulness, is of importance as it can result in problems and can render horses unsuitable for inexperienced riders. Early experience, including handling during infancy, may influence the horse's adult behaviour and reduce its fear of humans and other potentially frigthening situations. In the various species studied, handling has generally been undertaken during the neonatal period. The aim of the present study was to test the effects of handling young horses around the time of weaning, a period which has been demonstrated to be effective in increasing ease of handling in cattle and goats. Sixteen Anglo-Arab foals were handled for 12 days either immediately following weaning (early handled: EH) or 21 days later (late handled: LH); eight additional non-handled foals served as controls (C). Handling consisted of haltering, gently petting all parts of the body, picking up feet and leading the foal over 120 m. During handling sessions, EH were easier to handle than LH: time taken to fit them with a halter, to pick up feet, and “walk-ratio” (time walking under constraint/total time walking) were significantly lower for EH. During subsequent tests conducted over 2 days, 4, and 7 months, as well as 10 months and to some extent 18 months after the end of handling period, EH and LH were easier to handle and less reactive than controls, although differences diminished with time. The period following weaning can therefore be qualified as an “optimal period” for handling. Some of the effects persist for at least 18 months.

Title The Man Who Listens To Behavior: Folk Wisdom And Behavior Analysis From A Real Horse Whisperer Type Journal Article
Year 1999 Publication JOURNAL OF THE EXPERIMENTAL ANALYSIS OF BEHAVIOR Abbreviated Journal J Exp Anal Behav
Volume 72 Issue 1 Pages 139-149
Keywords positive reinforcement, aversive control, learned helplessness, language, biological constraints,
Abstract The popular novel and movie The Horse Whisperer are based on the work of several real-life horse

whisperers, the most famous of whom is Monty Roberts. Over the last 50 years, Roberts has developed

a technique for training horses that is both more effective and less aversive than traditional training

techniques. An analysis of Roberts` methods (as described in his book, The Man Who Listens to Horses)

indicates a deep understanding of behavioral principles including positive reinforcement, timeout,

species-specific defense reactions, learned helplessness, and the behavioral analysis of language.

Roberts developed his theory and techniques on the basis of personal experience and folk wisdom,

and not as the result of formal training in behavior analysis. Behavior analysts can clearly learn from

such insightful yet behaviorally incorrect practitioners, just as such practitioners can benefit from

the objective science of behavior analysts.

Title Early experience affects developmental behaviour and timing of harem formation in Misaki horses Type Journal Article
Year 1998 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 59 Issue 4 Pages 253-263
Keywords Feral horse; Young male; Social behavior; Developmental stage
Abstract A study was made of the behavior of young male Misaki feral horses in the developmental stage, by observing nine of them once a week from January 1988 to December 1996. The relationship between behavior before separation and in the developmental stage was also investigated. This stage begins just after young males separate from their natal band or mothers, and it continues until they start to form harems. The duration of the developmental stage in the study ranged from 0.6 to 3.9 years, depending on the age of the young males at the time of separation. Young males associated with three types of social groups at the beginning of the developmental stage, according to their social groups before separation. These were bachelor groups, harem groups and wandering female groups. During this period, males joined the three groups, mixed sex groups and sometimes were solitary. It was considered that these associations provided a good opportunity for males to acquire different behavioral patterns and experiences before they entered the next stage. Depending on the groups with which they associated, young males that spent more time with bachelor groups had the longest average developmental stage. They associated with harem groups more often during the breeding season and more frequently with other groups or were solitary during the non-breeding season. This may be a transition period because by the end of this stage all males had spent time in solitude before forming their own harem bands.

Title A comparative study of culturally transmitted patterns of feeding habits in the chacma baboon Papio ursinus and the vervet monkey Cercopithecus aethiops Type Journal Article
Year 1981 Publication Folia Primatologica; International Journal of Primatology Abbreviated Journal Folia Primatol (Basel)
Volume 36 Issue 3-4 Pages 243-263
Keywords Age Factors; Animals; *Cercopithecus; *Cercopithecus aethiops; Culture; *Feeding Behavior; Female; Group Structure; Learning; Male; *Papio; Social Class; Teaching
Abstract Japanese workers have studied social acquisition patterns of new feeding habits in Macaca fuscata which they have termed precultural. The present study investigates the same phenomenon in the chacma baboon and the vervet monkey in their natural habitat. The questions addressed are: (1) How a new feeding habit enters a troop and by which age and sex category, also how it is propagated? (2) When individuals are permitted with a choice between palatable and unpalatable food, can they learn by demonstration only or do they have to pass through a direct learning process? (3) Can the results from the above questions be explained by social parameters such as the social structure of the individual species? It was found that juvenile baboons discover new food and that after the discovery propagation is instantaneous. In vervets discovery is random among the age classes and propagation is slow and takes place through certain 'pivot' individuals. Both species fail to learn about palatability by demonstration but have to go through a direct learning process. This contrasts strongly with the forest baboon Mandrillus sphinx that have been shown to learn by demonstration. Socially, baboon juveniles stay closer to each other than the adults who force them to live at the periphery of the troop. Vervets again forage without precise sub-group formation. The link between social and cultural propagation and social structure is discussed on the basis of these findings.

Title Selectivity in large generalist herbivores: feeding patterns of African ungulates in a semi-arid habitat Type Journal Article
Year 1991 Publication African Journal of Ecology Abbreviated Journal Afr. J. Ecol.
Volume 29 Issue 4 Pages 302-315
Keywords diet; forage production; grazing; wildebeest; zebra
Abstract Feeding habits of free-ranging wildebeest and zebra were monitored in a semi-arid nature reserve, bordering the southwestern part of Kruger National Park, South Africa. The purpose of study was to distinguish and define the feeding niches of two roughage grazers that occur in similar habitat types. The monthly compositions of diets were evaluated by direct observations of feeding bouts over a period of two years when rainfall patterns were average and animal populations were stable. Other analyses evaluated the standing biomass of grass species in the reserve during the wet summer and dry winter seasons.

A considerable overlap of grass species composition was found in the diets of wildebeest and zebra. Ordination of bi-monthly records of the diet composition showed greater variations in scores of grasses in zebra diet in comparison to wildebeest. Seasonal patterns were more apparent in the wildebeest diet. Preference ranking of grass species indicated that zebra diet remained constant in winter and summer. Wildebeest diet however, alternated with seasons, showing high preferences during the winter months for grass species which were rejected during summer.

The combined assessment of results from three separate statistical methods analysing temporal patterns and preferences in diet composition revealed contradictory trends. The solution, however, relied on the initial assumptions posed. Hence, wildebeest and zebra are essentially generalist feeders which show a limited amount of preference in their choice of diet.
