Title (up) Sexual coercion in animal societies Type Journal Article
Year 1995 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 49 Issue 5 Pages 1345-1365
Keywords
Abstract In a wide range of animal species, males coerce females to mate with them, either by physically forcing them to mate, by harassing them until they mate or by punishing persistent refusal to mate. The first section of this paper argues that the possibility of forced copulation can generate arms races between males and females that may have substantial costs to both sexes. In the second section, it is suggested that sexual harassment commonly represents a `war of attrition' between the sexes; existing game theory models that may apply to sexual conflict over mating decisions are reviewed. The third section develops a simple prospective model for the evolution of intimidation by punishment in situations where males can raise the probability that females will accept their advances in future by punishing them for refusal to mate. Where the benefits of sexual coercion to males are high, all three male strategies may develop to a point where they have substantial costs to females. In the final section, evidence that female behaviour is adapted to minimizing these costs is reviewed.

Title (up) Social dominance in adult female mountain goats Type Journal Article
Year 1995 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 49 Issue 6 Pages 1449-1459
Keywords
Abstract The social behaviour of adult female mountain goats, Oreamnos americanus, was studied for 2 years in an unhunted population in west-central Alberta, Canada. Compared with other female ungulates, mountain goat females interacted aggressively much more frequently and their dominance ranks were less stable in time and less age-related. Goats were organized in a non-linear but non-random dominance hierarchy, with many reversals in rank. The best morphological predictor of dominance rank was horn length one year and body mass in the following year. Age was a weaker predictor of dominance status than what has been reported for other female ungulates. The ranks of individual goats changed between years and dominance rank one year was not a good predictor of rank the following year. These results suggest that linearity may only be possible when a contested resource can be defended. Dominant female goats did not forage more efficiently than subordinate goats, and dominant status did not affect the amount of time devoted to alert behaviour.

Title (up) The “migration” and grazing succession Type Book Chapter
Year 1995 Publication Serengeti: Dynamics of an Ecosystem Abbreviated Journal
Volume Issue Pages
Keywords
Abstract Editorial Reviews

Book Description

Originally published in 1979, Serengeti: Dynamics of an Ecosystem was immediately recognized as the first synthesis of the patterns and processes of a major ecosystem. A prototype for initial studies, Serengeti contains baseline data for further and comparative studies of ecosystems. The new Serengeti II builds on the information presented originally in Serengeti; both books together offer essential information and insights for ecology and conservation biology.

Title (up) The experience of self in the bottlenose dolphin Type Journal Article
Year 1995 Publication Consciousness and Cognition Abbreviated Journal Conscious Cogn
Volume 4 Issue 2 Pages 244-247
Keywords Animal Communication; Animals; *Awareness; Body Image; Dolphins/*psychology; Female; Humans; Male; *Self Concept; Social Behavior; Species Specificity; *Television; *Visual Perception
Abstract Marten and Psarakos have presented some evidence which suggests that objective self-awareness and possibly representations of self may characterize the dolphins' experience of self. Their research demonstrates the possibility of similarities in the sense of self between primate species and dolphins, although whether dolphins have subjective self-awareness, personal memories, and theories of self--all important facets of the sense of self in humans--was not examined. Clearly, even this limited evidence was difficult to achieve; the difficulties in adapting methods and coding behavior are quite apparent in their report. Future progress, however, may depend upon clarification of what are the necessary components for a sense of self and an explication of how these might be reflected in dolphin behavior. We are mindful of the authors' point (pp. 219 and 220) that the dolphin lives more in an acoustic than a visual environment. Thus, while tasks relying upon vision may reveal the presence or absence of the sense of self in primates, it might well be the case that in dolphins self-related experiences might be better revealed in auditory tasks. But then, what is the nature of human self-awareness in terms of audition? While both conceptual and methodological hurdles remain, Marten and Psarakos have demonstrated that important questions can be asked about the minds and phenomenal worlds of nonanthropoid species.

Title (up) The prevalence of abnormal behaviours in dressage, eventing and endurance horses in relation to stabling Type Journal Article
Year 1995 Publication The Veterinary record Abbreviated Journal Vet. Rec.
Volume 137 Issue 2 Pages 36-37
Keywords Animal Husbandry/*methods; Animals; *Behavior, Animal; Horse Diseases/*psychology; Horses; *Physical Conditioning, Animal; Prevalence; Questionnaires; *Stereotyped Behavior
Abstract The behaviour of horses competing in different disciplines was studied and the relationship between the time they spent out of the stable and the prevalence of abnormal behaviour was examined. The owners of dressage, eventing and endurance horses were sent a questionnaire and a total of 1101 responses were received, giving data on 1750 horses. The behaviours studied were wood-chewing, weaving, crib-biting/wind-sucking and box-walking. The reported percentage prevalences of abnormal behaviour for the dressage, eventing and endurance horses were 32.5, 30.8 and 19.5, respectively. The relationship between the time spent in the stable and the prevalence of abnormal behaviour was examined by chi 2 tests which showed that there were significant linear trends for the eventing group (P < 0.001) and the dressage group (P < 0.05). It is concluded that the time a horse spends out of the stable is related to the discipline for which it is being trained and in dressage and eventing horses the time spent in a stable is correlated with an increased risk of abnormal behaviour.

Title (up) The responses of female baboons (Papio cynocephalus ursinus) to anomalous social interactions: evidence for causal reasoning? Type Journal Article
Year 1995 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 109 Issue 2 Pages 134-141
Keywords Animals; Attention; Auditory Perception; *Awareness; *Concept Formation; *Dominance-Subordination; Fear; Female; Hierarchy, Social; Papio/*psychology; *Social Behavior; Social Environment; Vocalization, Animal
Abstract Baboons' (Papio cynocephalus ursinus) understanding of cause-effect relations in the context of social interactions was examined through use of a playback experiment. Under natural conditions, dominant female baboons often grunt to more subordinate mothers when interacting with their infants. Mothers occasionally respond to these grunts by uttering submissive fear barks. Subjects were played causally inconsistent call sequences in which a lower ranking female apparently grunted to a higher ranking female, and the higher ranking female apparently responded with fear barks. As a control, subjects heard a sequence made causally consistent by the inclusion of grunts from a 3rd female that was dominant to both of the others. Subjects responded significantly more strongly to the causally inconsistent sequences, suggesting that they recognized the factors that cause 1 individual to give submissive vocalizations to another.

Title (up) The social transmission of information and behaviour Type Journal Article
Year 1995 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 44 Issue 2-4 Pages 79-98
Keywords Social learning; Imitation; Social facilitation; Cultural transmission; Stereotypies
Abstract Social influences on established behaviour and on the acquisition of new information and behaviour are reviewed. Distinctions between social facilitation and contagious behaviour are drawn and suggestions for further research on contagious behaviour are made. Socially derived visual, olfactory and auditory cues are considered as important influences on behaviour and subsequent learning. The evidence supporting two potential mechanisms of social learning, i.e. stimulus enhancement followed by individual learning, and imitation, is reviewed in detail. It is argued that the functions of social learning are similarly heterogeneous and include motor skill acquisition, gathering of environmental information, and social conformity. Factors affecting the spread of socially acquired skills, including the social relationship between demonstrator and observer, are highlighted. Lastly, the few studies of social learning that have been conducted with domestic species are reviewed and potential applied goals that could stimulate further research in this area are suggested.

Title (up) Toward a theory of dominance hierarchies: effects of assessment, group size, and variation in fighting ability Type Journal Article
Year 1995 Publication Behavioral Ecology Abbreviated Journal Behav. Ecol.
Volume 6 Issue 4 Pages 416-423
Keywords
Abstract We introduce assessment to the analysis of dominance hierarchies by exploring the effect of an evolutionarily stable fighting rule when there is variation in resource holding potential (RHP) and RHP is not a perfectly reliable predictor of the outcome of a fight. With assessment, the probability of a linear hierarchy decreases with group size but can remain appreciable for groups of up to seven or eight individuals, whereas it decreases virtually to zero if there is no assessment. The probability of a hierarchy that correlates perfectly with RHP is low unless group size is small.
