  Title Sexual behavior in geldings Type Journal Article
  Year 1995 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 46 Issue 1-2 Pages 133-135  
  Keywords  
  Abstract Abstract

In response to a request published in Equus, a magazine for those interested in horses, 85 owners of older geldings exhibiting sexual behavior completed history forms. The mean age of geldings was 16 f 5 years. Only 39 of the owners had had the gelding for at least a year before the behavior was noted. These cases could be used to determine the true age of onset of the problem. When log survivorship was used to determine whether there were one or two different populations, a break or change in the slope at age 16 indicated that there are two populations. One population shows the behavior from the time of castration and the other first exhibits the behavior in old age, possibly in response to an ACTH secreting pituitary adenoma. A total of 40% of the horses were Quarterhorses, the most numerous breed in the US; 78% of the horses were purebreds. Fewer than half the owners knew the age at which their horse had been castrated because they did not own the horse at the time.

The mean age at castration, when known, was 3.3 f 2.5 years. The reason for contacting us was sexual behavior (70%), aggression (24%). or some other problem ( 1 o/o). Whether or not aggression was the presenting problem, most of the horses showed aggression (95%), particularly towards other geldings (88%)) but also towards people (3 1%). Copulatory behavior (mounting) was shown by 69% of the geldings and half of those were able to intromit. These findings indicate that the sexual behavior of geldings is a problem for owners and that aggression usually accompanies sexual behavior.

The owners were encouraged to send serum samples taken before and after human chorionic gonadotropin (HCG) administration for testosterone and estrone sulfate analysis to determine whether residual testicular tissue was responsible for the horse’s behavior. Of the 14 horses tested, only one had elevated levels of testosterone indicating that there was residual testicular tissue. A total of six of the owners agreed to treat their horses with cyproheptadine at a dose of 8 mg day- ’ gradually increased to 88 mg day- ’ per horse. A total of three of the horses showed a decline in sexual and aggressive behavior, one got worse and two had side effects and treatment was withdrawn.

  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 Ecology and Behaviour of the African Buffalo: Social Inequality and Decision Making Type Book Whole
  Year 1995 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords  
  Abstract What are the benefits that animals gain from living in a social group? This question has been the primary focus of the author's ecological interest. After many years of original and innovative research on the African buffalo, particularly at Lake Manyara in northern Tanzania, Herbert Prins has now summarized the results of much of this widely-respected work in this fascinating book. While advantages in reduction of the risks of predation or in increased efficiency of foraging on certain types of resources are now widely recognized, until now there has been less attention paid to the idea of the animals themselves as `information centres' and the extent to which the individual may be able to make use of information gathered by conspecifics, adjusting its own behaviour in response. Such a case-study has wide implications for research on social structure and organization in other species, and these are explored within the book. However, it is not a book aimed simply at the academic researcher, zoologist and behavioural ecologist; since it is written in a readable and accessible style, the book will also be enjoyed by wildlife enthusiasts, interested naturalists, wildlife biologists and wildlife managers.

  Title 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.
