The sex ratio at birth (usually denoted as M/T=male divided by total births) is influenced by cultural factors. The Chinese Zodiac holds that women born in the Fire Horse year (1966) would be unlucky. It has been shown that significantly less children were born in Japan in this year. ...

The size-sex relationship and sexual differences of sixArisaemaspecies native to Japan were investigated. The size-sex relationship showed almost the same pattern in all species. When the plant was small in size, the sex expression was male, and sex expression changed from male to female as the...
The mating behaviour and reproductive success of male Japanese macaques ( Macaca fuscata ) were studied in relation to the female sexual cycles, which wer... M Inoue,F Mitsunaga,M Nozaki,... - 《Primates》 被引量: 305发表: 1993年 The interaction of male and female reproductive strategies ...
Ideally, the number and gender ratio of Japanese and Thai participants should be equal. However, due to various restrictions, the number of participants and the ratio of male and female participants in this study were skewed. Third, since the study design was cross-sectional, we cannot draw ...
Effect of operational sex ratio on female–female versus male–male competitive aggression We compared the patterns of female–female and male–male competition in Japanese medaka (Oryzias latipes) in response to changes in the operational sex ra... JWA Grant,PE Foam - 《Revue Canadienne De ...
Female Japanese macaques (Macaca fuscata), in certain populations, routinely engage in female–male mounting. In this study, we documented patterns of vulvar, perineal and anal (VPA) stimulation during female–male mounting in Japanese macaques. During approximately 45% of the female–male mounts an...
Biased mating due to female preferences towards certain traits in males is a major mechanism driving sexual selection, and may constitute an important evolutionary force in organisms with sexual reproduction. In birds, although the role of male ornamentation, plumage coloration, genetic dissimilarity, an...

Electric fields radiated from the same ingested source in the small intestines of the Japanese adult male and female models are computed at vertically equi-spaced receiving points on those surfaces using the finite-difference time- domain (FDTD) method. Both amplitude variations in the frequency rang...
