Abstract: Editorial Reviews
From Booklist
“Problem” horses are usually horses that are trying to tell their owners that something is wrong and reacting in the only way they know how. Lesley Bayley leads the reader through Richard Maxwell's system of understanding equine psychology and for overcoming some of the natural responses that horses use in situations that frighten or confuse them. Beginning with two chapters on how horses communicate with each other (and with their owners), the authors go on to describe the effects of pain on the horse's behavior. Two chapters on establishing trust with older, difficult horses and with “starting” (breaking in) foals and young horses lead into the final sections on dealing with specific behavioral problems. The authors stress that positive reinforcement of desired behaviors will achieve the desired results, and that understanding why a horse is acting the way it does goes a long way toward getting it to develop desirable habits or toward changing undesirable conduct. This will be an extremely useful adjunct to all of the how-to books on riding and horse care. Nancy Bent
Book Description

Krebs, J. R., & Davies, N. B. (1997). Behavioural ecology : an evolutionary approach. Cambridge, Mass.: Blackwell Science.
Abstract: ntended for graduate and upper level undergraduate courses in behavioural ecology where students are already familiar with the basic ideas, this book continues to define the subject. A completely new set of contributions has been brought together once more to take account of the many exciting new developments in the field. Each chapter presents a balanced view of the subject, integrating a clear exposition of the theory with a critical discussion of how predictions have been tested by experiments and comparative studies. In addition, the book points to unreconciled issues and possible future developments. Edited by two of the most highly regarded experts in the field, this new volume contains contributions from an international authorship and continues the tradition of clarity and accessibility established by the three previous editions.

Abstract: In 1972, four aerial censuses were carried out to assess the annual migration of zebra and wildebeest between Tarangire National Park and Simanjiro Plains. About 6000 zebra and 10,000 wildebeest were in the Plains in the middle of the rainy season, in April. During the dry season in August the animals were concentrated in the Park. The migration from the Park to the Plains started at beginning of the rains, in November/December. Recent censuses by Tanzania Wildlife Conservation Monitoring (TWCM, 1991, 1995) indicate that an estimated 23,000 zebra and 11,000 wildebeest migrate into the Park from Simanjiro and other wet season areas. Encroaching cultivation is a threat to the migration corridors and sustainability of the ecosystem . Providing benefits from wildlife to communities around the park would safeguard the future of the wildlife.

Abstract: A grooming posture previously reported for two wild chimpanzee (Pan troglodytes) communities developed spontaneously in a captive group of the same species. This offered a unique opportunity to follow the propagation of a new social custom. The posture consists of two partners grasping hands--either both right hands or both left hands--and raising the arms in an A-frame above their heads while mutually grooming with their free hands. The propagation of this pattern was followed over a 5 year period. In the beginning, handclasps were always initiated by the same adult female. This female initiated the posture mainly with her adult female kin. In subsequent years, these relatives became frequent participants in the posture with each other as well as with nonrelatives. Over the years the posture increased in frequency and duration and spread to the majority of adults and also to a few adolescents and older juveniles. The pattern persisted after removal of the apparent originator.

Abstract: This is the first study to investigate the short-term effects of high population density on captive chimpanzees (Pan troglodytes). Subjects of the study were 45 chimpanzees living in five different groups at the Yerkes Regional Primate Research Center. The groups were observed under two conditions: 1) when they had access to both the indoor and outdoor sections of their enclosures; 2) during cold days when they were locked into the indoor runs, which reduced the available space by more than half. Under the high-density condition, allogrooming and submissive greetings decreased, but juvenile play increased. Remarkably, the rate of various forms of agonistic behavior, such as aggression, bluff charge, bluff display, and hooting, occurred less frequently under the high-density condition. This general decrease in adult social activity, including agonistic behavior, can be interpreted as an inhibition strategy to reduce opportunities for conflict when interindividual distances are reduced. This strategy is probably effective only in the short run, however. Behavioral indicators of anxiety, such as rough scratching and yawning, showed elevated rates, suggesting increased social tension under the high-density condition.

Abstract: A popular view is that high population density promotes behavioural pathology, particularly increased aggression. In contrast, according to a coping model, some primates have behavioural mechanisms (e.g. formal displays, reconciliation and grooming) that regulate social tensions and control the negative consequences of crowding. Seven captive rhesus monkey groups, Macaca mulattawere observed over a wide range of population densities where high-density groups were over 2000 times more crowded than low-density free-ranging groups. As density increased, male rhesus monkeys increased grooming and huddling but did not increase rates of aggression. Females increased all categories of behaviour examined (heavy aggression, mild aggression, formal bared-teeth displays, grooming and huddling), but the increases were not distributed uniformly to all classes of partners. Females increased only grooming, huddling and appeasement displays to males, increased only aggression and huddling with kin and increased all categories of behaviour to non-kin adult females. There were no differences in the percentage of aggressive conflicts reconciled across density conditions. Increased density had different effects on particular relationships. Relationships between females and males were characterized by a coping pattern in which animals modified their behaviour in ways that may decrease aggression under crowded conditions. Female relationships with kin and non-kin were characterized by increases in both aggression and friendly interactions as density increased. The different patterns of response to higher density may reflect different strategies depending on the strength and stability of relationships and the potential consequences if certain relationships are disrupted.1997The Association for the Study of Animal Behaviour
