  Title Dominance relationships between adult Plains zebra stallions in semi – captivity Type Journal Article
  Year 1988 Publication Behaviour Abbreviated Journal Behaviour  
  Volume 104 Issue 3-4 Pages 300-319  
  Keywords  
  Abstract The relationships between 4-5 adult zebra stallions, living in a safari park, were investigated over a period of 5 years. Asymmetries in the distributions of a number of behaviours could be explained by adopting dominance as an intervening variable. Dominance in stallions was of a bipolar nature with on the one hand behaviours representing subordinance and defence, and on the other hand behaviours reinforcing and confirming dominance. Expression of formal dominance seems to play a minor role. The dyadic relationships of stallions differed as to the number of behaviours reflecting dominance relationships. Although often linear rank-orders could be constructed, these rank-orders were not necessarily identical. This means that the concept of dominance is of only limited value for describing relationships between zebra stallions.

  Title A case of male infanticide in Equus przewalskii Type Journal Article
  Year 1988 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 21 Issue 1-2 Pages 187-190  
  Keywords  
  Abstract Following the introduction of a new stallion to a band of E. przewalskii mares two births, both of male foals, resulted in foal death due to injuries sustained in the first day of life. Neither foal was sired by the new herd stallion. The second foal death was the results of an observed attack on the newborn male and is described here. Subsequently births in the same enclosure and, in one instance, to the same mare whose previous foal was killed, were of foals sired by the new stallion and were uneventful, with 3 male foals surviving to date.

  Title Przewalski's horse – putting the wild horse back in the wild Type Journal Article
  Year 1988 Publication Oryx Abbreviated Journal Oryx  
  Volume 22 Issue Pages 154-157  
  Keywords Equidae genetics.  
  Abstract The Asian wild horse, or Przewalski's horse (Equus przewalskii), is believed to currently survive only in captivity. There are more than 660 individuals in over 70 zoological collections, and animals are available for reintroduction. The Przewalski's horse had been bred in captivity for 12 generations, and inbreeding has occurred. Genetic variability has been lost, and released animals will require acclimatization on or near release sites. In China, a program is under way for acclimatization, breeding, and release of wild horses, and plans are being made for a similar program in Mongolia. (LCA)

  Title Does Biology Constrain Culture? Type Journal Article
  Year 1988 Publication American Anthropologist Abbreviated Journal Am Anthropol  
  Volume 90 Issue 4 Pages 819-831  
  Keywords models, learning, evolution, culture, fitness, adaptive, environment, human, natural selection, behavior  
  Abstract Most social scientists would agree that the capacity for human culture was probably fashioned by natural selection, but they disagree about the implications of this supposition. Some believe that natural selection imposes important constraints on the ways in which culture can vary, while others believe that any such constraints must be negligible. This article employs a “thought experiment” to demonstrate that neither of these positions can be justified by appeal to general properties of culture or of evolution. Natural selection can produce mechanisms of cultural transmission that are neither adaptive nor consistent with the predictions of acultural evolutionary models (those ignoring cultural evolution). On the other hand, natural selection can also produce mechanisms of cultural transmission that are highly consistent with acultural models. Thus, neither side of the sociobiology debate is justified in dismissing the arguments of the other. Natural selection may impose significant constraints on some human behaviors, but negligible constraints on others. Models of simultaneous genetic/cultural evolution will be useful in identifying domains in which acultural evolutionary models are, and are not, likely to be useful.

  Title Testis size and onset of spermatogenesis in Cape mountain zebras (Equus zebra zebra) Type Journal Article
  Year 1988 Publication Journal of Reproduction and Fertility Abbreviated Journal J Reprod Fert  
  Volume 83 Issue Pages 371-375  
  Keywords mountain zebra; testis size; spermatogenesis  
  Abstract Testis mass of adult Cape mountain zebra stallions (mean 70·0 g) was appreciably less than that of other zebra species and domestic horses. The histological appearance of the testes of 11-, 24- and 29-month-old colts was typically prepubertal. Spermatogenic activity of a 4-year-old stallion obtained at the end of summer was at a very low level, while a 4·5-year-old stallion obtained 6 weeks after the winter solstice showed a marked increase in spermatogenesis compared with the 4-year-old. Stallions 6·5-19 years of age collected in different seasons all showed active spermatogenesis.
