Fourteen female Japanese monkeys of the Arashiyama-B group ranging in age from 11 to 29 years were observed to elucidate the
behavioral characteristics of aging monkeys. A positive significant correlation was found between the occurrences of rest
and age, and a negative significant correlation between the occurrences of auto-grooming and age. Younger female monkeys tended
to be in contact with or in proximity to group members, while older female monkeys tended to spend much more time alone. As
for the grooming interactions, younger female monkeys more often groomed others than did older female monkeys. Also, the former
engaged in grooming more frequently than in being groomed, while the latter spent more time in being groomed than in grooming.
The old female monkeys showed no marked decline in rank, but some of them were surpassed by their adult daughters. 相似文献

This study documents age-related changes in the interactions of wild-born cynomolgus macaque mothers and their infants living
in individual cages during the first 14 weeks of infant life. Body contact between mother and infant, maternal holding, and
infant sucking were found to decrease, and the mothers showed an increased frequency of aggression toward their infants with
age. These results were broadly similar to those reported for mother-infant interactions in other macaques living in social
groups. Nevertheless, a clear difference between the present cynomolgus macaques and other macaques in social groups was apparent.
The cynomolgus macaque mothers tended to permit their infants to move about freely without displaying maternal protectiveness
such as restraint or retrieval, unlike other macaque mothers in social groups. Such maternal behaviors might derive from the
experience of living in individual cages for many years and the relative safety of living in individual cages. The lack of
maternal restraint and retrieval could be responsible for the observed sex differences in behavior: male infants moved more
actively, and broke, and made contact with their mothers more frequently than did female infants. Moreover, mothers of female
infants held and groomed them more frequently and were less aggressive toward them. 相似文献

Parturition behavior of a multiparous female and her interactions with group members throughout the birth process were recorded
for a free-ranging Japanese monkey (Macaca fuscata). The female showed evidence of 18 contractions during the 35 min prior to delivery, with a mean duration and a mean intercontraction
interval of 30 sec and 96 sec, respectively. These values were similar to those in individually caged Japanese monkeys. Some
adult females remained in proximity to the female who was giving birth during the prepartum phase, and her 2-year-old daughter
watched the delivery of the infant. Even during the prepartum phase the female moved in order to keep up with the group which
traveled from the feeding site to a sleeping site in the forest. 相似文献

Cutaneous leishmaniasis (CL) is gaining attention as a public health problem. We present two cases of CL imported from Syria and Venezuela in Japan. We diagnosed them as CL non-invasively by the direct boil loop-mediated isothermal amplification method and an innovative sequencing method using the MinION? sequencer. This report demonstrates that our procedure could be useful for the diagnosis of CL in both clinical and epidemiological settings. 相似文献

We describe the social relationships of young adult female Japanese macaques (Macaca fuscata) in a free-ranging troop in Arashiyama, Kyoto, Japan, who remained nulliparous beyond the ordinary age of first birth because of contraceptive administration. We observed 12 young nulliparous adult females (6–9 years old) for 270 h and 10 min from 2 February to 5 October 2010. The majority maintained close relationships with their mothers through proximity and grooming, whereas a few had very infrequent social interactions with their mothers. Most had asymmetrical grooming relationships; the grooming they received from unrelated adult females was less than the grooming they gave. Young adult females who had less frequent interactions with their mothers by either proximity or grooming received more grooming from a larger number of unrelated adult females than did those who had more frequent social interactions with their mothers. These results indicate that most young adult females who remained nulliparous beyond the ordinary age of first birth tended to maintain close relationships with their mothers, and their grooming relationships with unrelated adult females were inversely related to the degree of closeness with their mothers. 相似文献
