Do males have a better chance of mating when the number of estrous females is equal to or greater than the males' ordinal rank? Testing the hypothesis in Japanese macaques
This study was designed to test the hypothesis that male primates in multi‐male/multi‐female social groups with a clear male dominance hierarchy have a better chance of mating when the number of estrous females is equal to or greater than, as opposed to less than, the males' ordinal rank. I studied a Japanese macaque ( Macaca fuscata fuscata ) troop during mating seasons from 1992 to 1995. The mean daily operational sex ratio (OSR; the number of …
Triadic Positions of Tibetan Macaques Huddling at a Sleeping Site
Changes of dominance rank, age, and tenure of wild Japanese macaque males in the kinkazan a troop during seven years
Female reproductive parameters and fruit availability
This study examined the onset of estrus, nutritional conditions during the mating season, and female reproductive parameters in a troop of unprovisioned Japanese macaques ( Macaca fuscata fuscata ). The mean interbirth interval (IBI) was 25.1 mo, suggesting a 2‐yr birth cycle. The mean IBI following the death of an infant before the mating season was only 19.8 mo, whereas the mean IBI was 27.8 mo when the infant survived. Estrus occurred during t…
Influence of fluctuation in the operational sex ratio to mating of troop and non-troop male Japanese macaques for four years on Kinkazan Island, Japan
Variation in Intergroup Encounters in Two Populations of Japanese Macaques
Does troop size of wild Japanese macaques influence birth rate and infant mortality in the absence of predators?
Aggressive intergroup encounters in two populations of Japanese macaques (Macaca fuscata)
Reproduction of wild Japanese macaque females of Yakushima and Kinkazan Islands
Comparative study of grooming relationships among wild Japanese macaques in Kinkazan A troop and Yakushima M troop
Male life history in natural populations of Japanese macaques
Huddling relationships in night sleeping groups among wild Japanese macaques in Kinkazan Island during winter
Tobacco use among Japanese schoolchildren
Over the past two decades many studies have shown associations between smoking and increased health problems. Smoking among children is especially a major public health concern. Preventing young people from developing a smoking habit is an important goal for school health education. In Japan, it is difficult to collect accurate data regarding adolescent smoking behaviour, because in Japan smoking under the age of 20 is prohibited by law. Therefor…
