Climbing the Virtual Stepladder
The aim of this project was to undertake curiosity-based research on the possibilities that the current generation of virtual reality (VR) technology can offer for a movement-based artist. This focused on the interplay between real and virtual spaces, looking specifically at how the technology impacts on the roles of audience and performer. Investigation into how VR can offer interactive movement-based experiences, such as those using real object…

Primate Ecology and Conservation
The survival of primates in their natural habitats is of growing concern to primatologists, ecologists and conservationists. In this volume, research on feeding behaviour, nutrition and digestive physiology from captive and wild primates is presented. Correlates of the habitat and social organisation are discussed, and then integrated with the pressing problem of how to conserve primates. Broad issues of confrontation between human and non-human …
Reproduction in the vervet monkey ( Cercopithecus aethiops )
The menstrual cycles of 17 multiparous vervet monkeys were studied. Based on estradiol, progesterone, and LH profiles, ovulation is predicted to occur on day 13 of the 32.4‐day menstrual cycle. Estradiol peaked on the day preceding the LH peak in 75% of cycles. Average luteal phase length (progesterone greater than 4 nmol/l) was 18 days, with progesterone rising above 4 nmol/l on the day of the LH peak. Vaginal cytology and perianal skin colorati…

Pregnancy outcome in free‐ranging vervet monkeys ( Cercopithecus aethiops )
A preliminary assessment of individual female differences in conception rate and fetal wastage has been determined for a population of wild vervet monkeys ( Cercopithecus aethiops ). One of three troops of vervet monkeys, the subjects of a long‐term behavioral study, was trapped and blood was obtained for electrophoretic analysis. Pregnant females exhibited a distinctive serum aminopeptidase phenotype allowing a conclusive determination of pregna…
The detection of ovulation and early pregnancy in the baboon by direct measurement of conjugated steroids in urine
The pattern of excretion of urinary steroid metabolites in the olive baboon ( Papio anubis ) was examined during the menstrual cycle and in conception cycles in which embryos were surgically removed at intervals between day 11 and day 21 (day 0 = day of preovulatory estrogen peak). Conjugated estrone and pregnanediol‐3α‐glucuronide were measured in overnight urine samples by direct, nonextraction assays, and the levels were indexed by creatinine.…
Reproduction in the vervet monkey ( Cercopithecus aethiops )
Menstrual patterns and progesterone levels were monitored for 5 years from a cohort of 28 female vervet monkeys that were individually caged indoors. Three distinct cycle types (short, normal, and prolonged) were defined according to cycle length. Mean length of the normal cycle (32.5 days) and menses duration (4.8 days) are in agreement with previous reports. Prolonged cycles (> 50 days) contributed 20% of the total, with a decreased incidence d…
Reproduction in the vervet monkey ( Cercopithecus aethiops )
To test whether the male could contribute to the birth peak seen in both wild and captive vervets, testicular volume and peripheral testosterone concentration were measured monthly in nine adults throughout a 14‐month period. Volume was an average of 15% greater during the months of June to September, the period of natural breeding activity in the wild, than at other times of the year. Testosterone concentration rose throughout the time period bu…
Reproductive biology of Sykes and blue monkeys ( Cercopithecus mitis )
Thirty‐five live births were recorded over a 5‐year period from three subspecies of the mitis (Sykes and blue) monkey ( Cercopithecus mitis ) maintained outdoors in single‐male harem breeding groups. There was no indication of birth seasonality. Females of one subspecies, C. m. kolbi , were individually caged, and basic reproductive parameters were monitored. A menstrual cycle length of 31.9 ± 6.0 days was recorded, and there were a large number …
Brief report
Hematologic values are presented for the Sykes monkey ( Cercopithecus mitis albogularis ). The values are, in general, similar to published findings for other primate species. Elevated hemoglobin, possibly caused by high altitude, was noted. Significant differences of several values between males and females are discussed
