| psychoendocrine correlates of sociosexual responsivity in older premenopausal primates. | cycling older premenopausal female bonnet macaques (17 to 18 years) show decreased attractivity (mounting indices) and responsivity to males in short-term pair-testing compared to younger, fully mature cycling females (9 to 13 years). comparison of age-group mean circulating levels of estrogen, progesterone, and testosterone during four phases of the menstrual cycle shows a significant decrement in older females only in the height of the estrogen surge during the periovulatory (estrous) phase of ... | 1982 | 6890147 |
| sociosexual and hormonal changes in aging female bonnet macaques. | a comparison of younger mature and older perimenopausal female bonnet macaques showed differences in sexual interaction with males. older females evoked significantly fewer copulations than did younger females. although older females were cycling regularly, the midcycle (estrus) peaking of sexual interaction and levels of plasma estradiol were less pronounced in older than in younger females. younger females were mounted more during estrus than during the luteal phase of their cycles, and the fr ... | 1982 | 7200997 |
| physiology of maternal separation in a bonnet macaque infant. | a bonnet monkey infant (m. radiata) was monitored both physiologically and behaviorally during a separation experiment in which both its mother and other conspecifiecs were removed from its social group leaving the bonnet infant with three adult pigtailed females. the separated infant exhibited the characteristic slouched posture of depression and physiological changes including decreases in the heart rate and body temperature, increases in cardiac arrhythmias, and alterations in sleep patterns, ... | 1982 | 32197564 |
| a comparison of mother and nonmother behaviors during birth season in two species of captive macaques. | 9 adult rhesus macaque females (macaca mulatta) and 7 adult bonnet macaque females (macaca radiata) were observed during the birth season to identify possible differences between mothers and nonmothers in time budgets and social interactions. rhesus mothers spent less time moving, feeding, grooming others and aiding others than rhesus nonmothers did. bonnet mothers spent less time resting and moving, but more time in huddling groups than bonnet nonmothers did. mothers of both species were approa ... | 1982 | 7095663 |
| the bonnet monkey (macaca radiata): a model for the study of gonadotropin dynamics during fasting in the human. | general hospital and harvard medical school, boston postmenopausal women excrete significantly greater quantities of radioimmunoassayable luteinizing hormone (lh) and follicle stimulating hormone (fsh) during fasting than during the control or refeeding periods. the concentrations of these gonadotropins in the serum, however, are not affected. in the present studies, ovariectomized bonnet monkeys (macaca radiata) and ovariectomized sprague-dawley rats were studied to compare the effects of fasti ... | 1982 | 32197561 |
| females without infants: mating strategies in two species of captive macaques. | bonnet (macaca radiata) and rhesus (macaca mulatta) macaque females were observed during the breeding season to evaluate differences in mating strategies between females without infants and females with dependent offspring. rhesus nonmothers participated in consortships earlier in the breeding season and initiated and received more approaches with adult males than rhesus mothers did. bonnet nonmothers entered estrus earlier, began copulating earlier, and approached and presented to adult males m ... | 1983 | 6683218 |
| brief report: chromosomal analysis of perinatal death in macaca mulatta and macaca radiata. | peripheral blood samples from 53 macaque perinatal deaths at the california primate research center (cprc) were cultured to produce chromosomes for analysis. karyotypes were constructed for 26 successful cultures and revealed no apparent chromosomal anomalies. a genetic screening program at primate breeding facilities is important for estimating the frequency of chromosomal anomalies in macaques and for understanding the contribution of chromosomal anomalies to reproductive loss and congenital m ... | 1983 | 31986849 |
| a binding protein for lysosomal enzymes isolated from brain by phosphomannan-sepharose chromatography. | we have isolated from monkey (macaca radiata) brain lysosomal fraction by phosphomannan-sepharose chromatography a protein that binds four different lysosomal enzymes, beta-hexosaminidase, beta-glucuronidase, alpha-l-fucosidase and arylsulfatase. the isolated protein which appeared in an aggregated homogeneous form on gel electrophoresis under non-denaturing conditions at both ph 8.3 and ph 5.0 was found to be heterogeneous on sds-gel electrophoresis with molecular weights less than 67,000. bind ... | 1983 | 6847656 |
