Recent status of hybridization monitoring of alien macaque species on the Boso Peninsula
Impact of Covid-19 damage on Japanese monkeys survey in Fukushima
The Number of Louse Eggs on Wild Japanese Macaques (Macaca fuscata) Varies with Age, but Not with Sex or Season
During grooming, primates remove harmful ectoparasites, such as ticks and lice, and there is direct evidence for a health benefit of tick removal. Grooming behaviors differ among primates with respect to age and sex. Moreover, the number of ectoparasite may exhibit seasonal variation. Therefore the number of ectoparasites on a host may vary with effects, host age and sex, and season. However, these effects have not been a focus of louse infestati…
Morphological changes of female reproductive organs of Japanese monkeys with reproductive conditions
Milk secretion in pregnancy among free‐ranging Japanese macaques
Milking under anesthesia in pregnant free‐ranging Japanese macaques ( Macaca fuscata ) directly revealed lactation in gestation at Jigokudani Monkey Park, the Shiga Heights, Nagano Prefecture, Japan, from 12 to 14 February 1992. Multiparae secreted milk at 76–97 days of estimated fertilization age when the birth intervals to the next offspring were 2 years. The observation of sucking behavior from February 1991 to March 1992 indicated that concur…
Lipofuscin in the corpus luteum of macaque ovaries
Copulatory behavior unaccompanied by ovulation in the Japanese monkey (Macaca fuscata)
Pregnancy-induced sclerosis in the myometrial vessels of cynomolgus monkeys (Macaca fascicularis)
Rise in age of sexual maturation in male Japanese monkeys at Takasakiyama in relation to nutritional conditions
Immobilization with a single dose of ketamine hydrochloride and a combination of xylazine hydrochloride-ketamine hydrochloride and antagonism by yohimbine hydrochloride in the Japanese monkey (Macaca …
