protein-losing enteropathy in six macaques.using intravenous administration of radioactive labeled chromic chloride, which binds to plasma proteins, protein-losing enteropathy was documented in 6 macaques (macaca mulatta and macaca arctoides) with progressive weight loss and hypoalbuminemia. four clinically normal macaques lost 0.5% +/- 0.1% of the label in feces over 4 days, compared with the diseased macaques, which lost from 1.0%--14.2% of the dose during the same period. lesions in the small intestine (lymphangiectasia, amyloidosis o ...19807451327
sociopharmacology of d-amphetamine in macaca arctoides.this study was designed to assess the effects of acute d-amphetamine pretreatment on the social behavior of a heterosexual group of adult m. arctoides. the dominance status had been previously determined by use of daily group food competition tests. prior to some sessions amphetamine was administered to a single group member; whereas on other occasions all subjects were drug treated. the effects of both the individual and concurrent pretreatments were compared to those produced by saline. furthe ...19807191115
behavioral and physiological evidence of sexual climax in the female stump-tailed macaque (macaca arctoides).intense tonic/clonic uterine contractions and sudden increases in heart rate coincided with the behavioral homolog of a male ejaculatory response (minus seminal emission) in a normal female stump-tailed macaque engaged in homosexual mounting episodes. the behavioral patterns were also observed in four of ten females during 5 to 40 percent of heterosexual copulations. these observations demonstrate the existence of an orgasmic response in a nonhuman primate.19807384791
lactose intolerance in the stumptail macaque (macaca arctoides): case report.a female stumptail macaque had signs of intermittant diarrhea and chronic weight loss over a 2-year period during which she was fed a commercial laboratory maintenance diet. intolerance of this individual to lactose, a ubiquitous constituent of most commercial primate diets, was diagnosed on the basis of lactose tolerance tests and favorable clinical response to dietary carbohydrate substitution with glucose. oral administration of varying doses of glucose to this animal consistently produced el ...19806772876
characteristics of the menstrual cycle in nonhuman primates. iii. timed mating in macaca arctoides.analysis of five years of reproductive data from macaca arctoides showed the mean menstrual cycle length was 29.9 +/- 4.4 days. using timed mating, a conception rate of 16.3% was observed. the highest conception rate occurred after matings on day 11 of the cycle. eight pregnancies went to term and the mean gestation length was 172.4 days. the sex ratio was 137.8 males per 100 females in fetuses obtained on day 100 post-conception.19807420409
the effects of opiate agonist and antagonist on serum prolactin in primates: possible role for endorphins in prolactin regulation.intravenous administration of the opiate receptor antagonist naloxone produced a significant reduction in basal serum prl concentrations in four male macaca arctoides. significant decreases from basal levels were found 15, 30, 45, 60, 90, 120, 150, and 180 min after the iv injection of 0.05 and 0.25 mg/kg naloxone. the iv administration of 0.4 mg/kg morphine produced rapid and significant increases in prl levels, while 0.04 mg/kg morphine or saline produced no change. both the dopamine receptor- ...1979221205
lens extraction with anterior chamber lens implantation in the macaque.three macaques (macaca arctoides) had anterior chamber implantations with the choyce mark viii lenses in 5 eyes. the eyes were monitored clinically and histologically for approximately 2 years. histologic sections verified that these lenses were well tolerated in the eyes of the macaques.1979111587
characteristics of the menstrual cycle in nonhuman primates. ii. ovulation and optimal mating times in macaques.an analysis of the results of 1,259 limited-duration matings was conducted on colonies of macaca arctoides and m. fascicularis. maximum conception occurred at a day of breeding/cycle length (db/cl) ratio of 0.40--0.41 with a range of db/cl ratios for successful matings from 0.39 to 0.44. these values are compared with published values for various endocrine parameters equated to cycle length.1979113545
characteristics of the menstrual cycle in nonhuman primates. i. similarities and dissimilarities between macaca fascicularis and macaca arctoides.comparative studies of reproductive characteristics were carried out on a colony of macaca fascicularis and m. arctoides. seasonal differences were not significant between species, and conceptions occurred throughout the year. the occurrence of short cycles ('luteal phase defect') was found in 2.9% of all m. fascicularis cycles and 1.5% of all m. arctoides cycles. long cycles (40-50 days) were found in 4.0% of all m. fascicularis cycles and 3.5% of all m. arctoides cycles. gestation lengths aver ...1979113537

effects of propranolol, minoxidil, and clofibrate on cholesterol-induced atherosclerosis in stumptail macaques (macaca arctoides).propanolol, minoxidil, and clofibrate, three different classes of pharmacological agents used clinically in various conditions related to atherosclerosis, were shown not to have any intrinsic potentiating effects on the development of atherosclerosis in stumptail macaques fed an atherogenic diet. we did obtain, however, some results that suggest that clofibrate and propranolol may exert some beneficial actions.1977405023
galactorrhea in a male stump-tailed macaque (macaca arctoides).a male macaca arctoides imported as an adult in 1966, has demonstrated bilateral galactorrhea since 1973. the animal has not shown any clinical signs of gynecomastia, ill health, or reproductive failure. a sample of the secretion expressed from his nipples contained 2-5% lactose.1976988433
short-term line of normal baboon mammary epithelial cells.cells from the breast fluids of 27 baboons (papio anubis), 4 stump-tailed macaques (macaca arctoides), and 5 rhesus macaques (m. mulatta) were grown in primary culture. a short-term mammary epithelial cell line (7 passages) was derived from cells of the breast fluids of 1 baboon. these cells were characterized as normal, epithelial, and baboon, by karyology, growth in both soft agar and methyl cellulose, and morphology by light and electron microscopy. papanicolaou smears of breast fluid and mam ...1976824456
catecholamine-containing nerve terminals in piloarrector muscles of stump-tailed macaques (macaca arctoides) and the effects of local injection of 6-, and 5-hydroxydopamine.the fluorescence histochemical method of falck-hillarp (62) demonstrates dense plexuses of catecholamine-containing nerves in the piloarrector muscles of adult stump-tailed macaques. when these muscle fibers are viewed under the electron microscope, most of the axon terminal profiles between them contain numerous dense-cored vesicles (adrenergic); the rest of the terminals contain mainly agranular vesicles (cholinergic). intradermal injections of 6-hydroxydopamine (6-ohda, 1 and 5 mg) or 5-hydro ...1976817620

the stump-tailed macaque: a promising laboratory primate.members of macaca speciosa have characteristics that make them suitable primates for neuropsychological investigation. they work well in discrimination training, have a varied behavioral repertoire and social interaction, and seem to be at least as intelligent as m. mulatta. they are docile and submit readily to laboratory routine.196314033533
baculum length and copulatory behavior in primates.the length of the baculum (os penis) was measured in 74 adult males representing 46 primate species. these data, and a review of previously published measurements, indicate that variation in baculum length among primates is related to taxonomic and behavioral differences. thus, many new world monkeys have shorter bacula, relative to body weight, than old world monkeys. the baculum is shorter in colobine monkeys than in cercopithecines. among the great apes, reduction of the baculum is more prono ...198731973483
efficacy of camera traps in detecting primates in hue saola nature reserve.camera trapping has been demonstrated to be an effective tool in surveying a suite of species, especially elusive mammals in rough terrains. the method has become increasingly common in primate surveys for both ground-dwelling and arboreal taxa in many tropical regions of the world. however, camera trapping has rarely been used to inventory primates in vietnam, although many species are under severe threats and in critical need of surveying for improved conservation measures. in this study, we e ...202032383126
malaria parasites in macaques in thailand: stump-tailed macaques (macaca arctoides) are new natural hosts for plasmodium knowlesi, plasmodium inui, plasmodium coatneyi and plasmodium fieldi.certain species of macaques are natural hosts of plasmodium knowlesi and plasmodium cynomolgi, which can both cause malaria in humans, and plasmodium inui, which can be experimentally transmitted to humans. a significant number of zoonotic malaria cases have been reported in humans throughout southeast asia, including thailand. there have been only two studies undertaken in thailand to identify malaria parasites in non-human primates in 6 provinces. the objective of this study was to determine t ...202033004070
seroprevalence of dengue, zika, and chikungunya viruses in wild monkeys in thailand.zoonotic pathogens such as arboviruses have comprised a significant proportion of emerging infectious diseases in humans. the role of wildlife species as reservoirs for arboviruses is poorly understood, especially in endemic areas such as southeast asia. this study aims to determine the exposure history of different macaque species from national parks in thailand to mosquito-borne flaviviruses and alphavirus by testing the serum samples collected from 25 northern pigtailed macaques, 33 stump-tai ...202032588813
correction to: dominance status and copulatory vocalizations among male stump-tailed macaques in thailand.in the original publication of the article the affiliations 1 and 3 were incorrectly published. the correct affiliations are given in this correction.202032447563
dominance status and copulatory vocalizations among male stump-tailed macaques in thailand.male copulation calls sometimes play important roles in sexual strategies, attracting conspecific females or advertising their social status to conspecific males. these calls generally occur in sexually competitive societies such as harem groups and multi-male and multi-female societies. however, the call functions remain unclear because of limited availability of data sets that include a large number of male and female animals in naturalistic environments, particularly in primates. here, we exa ...202032318928
locomotor kinematics of two semi-wild macaque species (macaca assamensis and macaca arctoides) in thailand.this project aimed to investigate primate locomotor kinematics noninvasively in the wild. semi-wild assamese and stump-tailed macaques were selected for the study, which was performed in thailand. we investigated their locomotor kinematics and its relationship to habitat use. the macaques' positional behavior was recorded with two video cameras, and kinematic parameters were estimated during terrestrial quadrupedal locomotion, using the markerless method. the data analyzed so far revealed that s ...201930870840
sperm concentration, coagulum weight, and testosterone levels differences according to social rank in male stump-tail macaques (macaca arctoides).in multi-female multi-male group-living species, both sexes can copulate with diverse partners. according to the priority of access model, high-ranking males have higher access to females during their fertile phases than the lower-ranking competitors. however, when females' ovarian cycles are synchronized, dominant males are unable to monopolize all females, which gives a chance to lower ranking males to sporadically copulate and increase their likelihood to fertilize a female. therefore, subord ...201930388471
macaca arctoides gammaherpesvirus 1 (strain herpesvirus macaca arctoides): virus sequence, phylogeny and characterisation of virus-transformed macaque and rabbit cell lines.herpesvirus macaca arctoides (hvma) has the propensity to transform macaque lymphocytes to lymphoblastoid cells (mal-1). inoculation of rabbits with cell-free virus-containing supernatant resulted in the development of malignant lymphomas and allowed isolation of immortalised hvma-transformed rabbit lymphocytes (htrl). in this study, the hvma genome sequence (approx. 167 kbp), its organisation, and novel aspects of virus latency are presented. ninety-one open reading frames were identified, of w ...201930291474
ancient hybridization and admixture in macaques (genus macaca) inferred from whole genome sequences.the evolutionary history of the stump-tailed macaque (macaca arctoides) and its genetic relationship to other macaques is a subject of continuing controversy. here, we have reported the first genome sequences of two stump-tailed macaques and one assamese macaque (m. assamensis). additionally, we have investigated the genetic diversity between macaque species and analyzed ancient hybridization events. genome-wide analyses demonstrated that the stump-tailed macaque is more closely related to sinic ...201829614345
molecular cytogenetic analysis of one african and five asian macaque species reveals identical karyotypes as in mandrill.the question how evolution and speciation work is one of the major interests of biology. especially, genetic including karyotypic evolution within primates is of special interest due to the close phylogenetic position of macaca and homo sapiens and the role as in vivo models in medical research, neuroscience, behavior, pharmacology, reproduction and acquired immune deficiency syndrome (aids).201829606908
annual variations in sexual hormones and births' frequency in female stump-tailed macaques (macaca arctoides).although the breeding seasonality in macaca arctoides have been studied over a long period of time, it is still controversial whether reproduction in this primate tend to increase during certain months of the year as it happens in most of the macaque species. many authors have classified macaca arctoides as not being seasonal species. nonetheless, there were no reports, about seasonal variations of female sexual hormones to demonstrate that asseveration. therefore, in the present study we collec ...201829227912
behavioral characterization of sleep in stumptail macaques (macaca arctoides) in exterior captivity by means of high-sensitivity videorecording.there are reasons to consider incomplete the description of sleep in many non-human primate species. recording animals by highly sensitive videos to obtain detailed descriptions of nighttime behavior and evidence of muscle activity while in a resting posture, seems a promising approach to the non-invasive study of sleep in non-human primates. the present work describes the use of ultrasensitive videocameras to record and analyze spontaneous nighttime behaviors in captive non-human primates. its ...199531924091
a twenty-one-year study of maternal dominance and secondary sex ratio in a colony group of stumptailed macaques (macaca arctoides).trivers and willard's theory of sex-ratio adjustment, as applied to cercopithecines, predicts that the ratio of male to female offspring will be greater for dominant than for subordinate mothers. a local-resourcexyhcompetition hypothesis predicts the reverse. to date, results from several species of macaque are inconsistent and often not statistically significant. in this 21 year study, a colony group of stumptailed macaques is added to the species previously studied. seventy-five offspring were ...199431936913
mirror-induced social facilitation in stumptailed macaques (macaca arctoides).seven adult female stumptailed macaques (macaca arctoides) were confronted alternately with their reflection in a mirror and with the mirror covered. the reflection elicited significantly more visual attention and social responding than the control stimulus, replicating previous findings. mirror-image stimulation did not significantly affect the subjects' manipulation of unfamiliar objects, but it did increase bout-lengths of episodes of drinking from a bottle containing orange juice. possible e ...199131948184
a twenty-year study of long-term and temporary dominance relations among stumptailed macaques (macaca arctoides).consistent individual differences in long-term dominance are a basic underlying assumption of hypotheses linking dominance and reproductive success. long-term and temporary dominance of a colony group of stumptailed macaques was studied for 20 years. there were two variously constituted groups for the first 4 years and a single group for the last 16. stumptails displayed the matrilineal dominance organization found for several other cercopithecine species. a method was devised to standardize ran ...198931964015
wounding patterns in three species of captive macaques.the incidence of wounding in captive groups of rhesus (macaca mulatta), pigtail (m. nemestrina), and stumptail (m. arctoides) macaques was studied for 21 months. groups were monitored daily for evidence of wounding. wounded animals were captured, treated by veterinary staff, and returned following recovery. records were kept on the age, sex, and species of the recipient, along with the type and location of wound. in each species of macaque, adult males incurred the highest frequency of wounds an ...198831973451
social interactions following parturition in stumptail macaques.the social behavior of six female stumptail macaques (macaca arctoides) living in a social group of 23-29 individuals was monitored before and after parturition and was compared to the social interactions of six nonpregnant females. pregnant and control females did not differ in terms of affiliative and most types of agonistic behavior performed or received. after parturition, new mothers interacted with more group members than did control females. new mothers received more grooming initiations ...198831968892
the stumptail macaques of china.the stumptail macaque species macaca thibetana and macaca arctoides replace one another from north to south in subtropical and tropical china. these species differ in external and cranial characters. neonatal pelage color is pale grayish-brown in m. thibetana and whitish in m. arctoides. in adults, ventral pelage is whitish in m. thibetana and brown in m. arctoides. the forehead and cheeks are thickly furred in adult m. thibetana and bald in m. arctoides. facial skin color typically is sexually ...198531986825
a statistical analysis of the social behavior of the male stumptail macaque (macaca arctoides).the social behavior of male stumptail macaques was analyzed in terms of behavioral sequences recorded during paired encounters in a large test cage. recurrent patterns of behavioral sequences were sought and used to hypothesize the structure of motivational systems of social behavior as has been done previously for other species. in addition to traditional statistical analyses to determine which dyadic behavioral sequences were nonrandom, there were several methodological innovations. instead of ...198232192238
venipuncture and vaginal swabbing in an enclosure occupied by a mixed-sex group of stumptailed macaques (macaca arctoides).procedures are described for vaginal swabbing and venipuncture in a gang-caged, mixed-sex group of stumptailed macaques. the design of the gang cages facilitated venipuncture and swabbing which were done without undue disturbance of the vivarium routine, without seriously stressing colony members, and without interfering with the monkeys' established social relationships.198231995904
the effectiveness of sampling methods in detecting copulatory behavior in macaca arctoides.the copulatory behavior of a social group of 18 stumptail macaques was observed for 171 hours over a period of 5 months. the occurrence of copulation and several quantitative measures of copulation were compared using sampling periods of 2 hours daily and continuous dawn-to-dusk observation. in this environment copulation was found to occur in brief bouts of relatively short duration. copulation was detected on 34% of the days observed with 2 hr sampling and 100% of the days with dtd sampling. t ...198131995908
