Socio-ecological and genetical study of the evolution of life histories of lemur species

我们分析了22年来野生环尾狐猴种群的人口统计数据。最长寿命为20岁(女性)和13岁(男性)。女性的平均寿命为4.8岁。成年雌性(&gt；4岁)平均出生率超过70%，无生殖衰老迹象。根据微卫星分析，确定了19个婴儿的亲缘关系。在这些婴儿中，只有四个是阿尔法男性的父亲。行为数据显示，发情的雌性与多只雄性交配，无论其级别如何。体质量无性别差异。他们的体重从1999年的2.2-2.3公斤下降到2011年的1.99公斤，这可能是许多因素造成的，包括环境变化。还分析了尾巴、臭腺和脸型的形态特征。为了研究褐狐猴授粉和种子传播过程中的基因流动，对两个特有树种的微卫星座位进行了分析。

We analyzed 22-year demographic data of a wild ringtailed lemur population. The longest life span was 20 years (female) and 13 years (male). The mean life span of females was 4.8 years. Mean birth rate of adult females (> 4 years) was over 70%, and no sign of reproductive senescence. Based on the microsatellite analyses, the paternities of 19 infants were decided. Out of them, only four infants were sired by alpha-males. Behavioral data showed that estrus females mated with multiple males, irrespective of their ranks. No sexual difference was observed in body mass. Their body mass decreased from 2.2-2.3 kg recorded in 1999 to 1.99 kg in 2011, which may have originated from many factors including environmental changes. Morphological features of tails, stink glands, and facial forms were also analyzed. Polymorphic microsatellite loci for two endemic trees were characterized in order to investigate gene flow via pollination and seed dispersal by brown lemur.
