Comparison of feeding behavior between two different-sized groups of Japanese macaques (Macaca fuscata yakui).
Group-living animals face intragroup scramble and intergroup contest competitions. Many studies have shown that larger groups bear the costs of intragroup scramble competition, which negatively affects the reproductive success of females. Unlike most primate species, Japanese macaques in the Yakushima coastal forest show increased reproductive success with group size. However, it remains unclea...
متن کاملThe interaction of male and female reproductive strategies and paternity in wild Japanese macaques, Macaca fuscata
Japanese macaques reside in large, mixed-sex social groups in which various reproductive strategies of both sexes operate simultaneously. This report represents the first study combining behavioural and genetic data to examine the interaction of male and female reproductive strategies in primates (N=15 adult males, N=15 adult females, Yakushima Island, Japan). During one mating season, socially...
متن کاملThe Special Column of Primate Behavior
It is a long-term policy to publish SPECIAL COLUMNs in Current Zoology, and I am delighted that the journal is publishing this special column devoted to the topic of Primate Behavior. The eight papers in this section present significant new data and synthesize these findings with existing information on sexual selection of human-being and behaviors of living primates. Dixson et al. found that t...
متن کاملGrowth Performance, Feeding Behavior and Physiological Responses of Young Growing Holstein Male Calves to Dietary Chromium-Methionine (Cr-Met) Supplementation Related to Body Weight and Age
This study was conducted to investigate the effect of dietary chromium-methionine (Cr-Met) supplementation on growth performance, feeding behavior and physiological responses of Holstein male calves during two different phases of body weight (BW). Twenty six (153.5±9.83 kg of BW) male calves were divided in two groups (n=13) and randomly assigned to treatments: 1) control and 2) Cr-Met (1.1 mg ...
متن کاملMultimodal Advertisement of Pregnancy in Free-Ranging Female Japanese Macaques (Macaca fuscata)
The role of multiple sexual signals in indicating the timing of female ovulation, and discrimination of this timing by males, has been particularly well studied among primates. However the exhibition of pregnancy signals, and how such signals might modulate male post-conception mating decisions, is still poorly understood. Here we aimed to determine if Japanese macaque males use changes in fema...
