Different types of dominance hierarchies reflect different social relationships in primates. In this study, we clarified the hierarchy and social relationships in a one-male unit of captive Rhinopithecus bieti observed between August 1998 and March 1999. Mean frequency of agonistic behaviour among adult females was 0.13 interactions per hour. Adult females exhibited a linear hierarchy with a reversal of 10.9%, indicating an unstable relationship; therefore, R. bieti appears to be a relaxed/tolerant species. The lack of a relationship between the agonistic ratio of the adult male towards adult females and their ranks indicated that males did not show increased aggression towards low-ranking females. Differentiated female affiliative relationships were loosely formed in terms of the male, and to some extent influenced by female estrus, implying that relationships between the male and females is influenced by estrus and not rank alone. A positive correlation between the agonistic ratio of adult females and their ranks showed that the degree to which one female negatively impacted others decreased with reduction in rank. Similarly, a positive correlation between the agonistic ratio of females and differences in rank suggests that a female had fewer negative effects on closely ranked individuals than distantly ranked ones. These data indicate that rank may influence relationships between females. A steeper slope of regression between the agonistic ratio and inter-female rank differences indicated that the extent of the power difference in high-ranking females exerting negative effects on low-ranking ones was larger during the mating season than the birth season, suggesting that rank may influence the mating success of females.

引用

Zoological Research 2015年第4期36卷 233-240页

作者： Huan LI Ming-Xia ZHANG Xiao-Jun YANG liang-wei cui Rui-Chang QUAN The Faculty of Forestry Southwest Forestry University Center for Integrative Conservation Xishuangbanna Tropical Botanical Garden Chinese Academy of Sciences The Faculty of Ecotourism Southwest Forestry University

To fill the gap in breeding biology information about the Red-Whiskered Bulbul （Pycnonotus jocosus）, in 2013, we studied the breeding biology of this species in Xishuangbanna, southwest China. The breeding began from February and continued until early August. The breeding strategy of P. jocosus was more flexible and their nests were only built in cultivated landscapes, whereas, no nest building in native tropical rain forest was found. Small open cup nests were built on 50 different plant species, and at heights ranging from 2.1±0.6 m above the ground （n=102）. The mean clutch size was 2.53±0.51 eggs （n=40） and the mean egg mass was 2.81±0.25 g （n=60）. The average incubation period was 11.1±0.5 days （n=14）, and the average nestling period was 11.0±0.8 days （n=31）. The overall nest success was 34.22%.The hatching and fledging showed either asynchrony or synchrony. Invertebrate food decreased with nestling age, whereas, plant food increased with nestling age. Moreover, distinct parental roles of the parents in nestling period were found. Compared with other passerine species, P. jocosus spent less time in incubating （58%）. The clutch size, incubation and nestling period of the P. jocosus in southwest China were different from those of the R jocosus in India.

作者： Sheng-Dong YUAN Han-Lan FEI Shao-Han ZHU liang-wei cui Huai-Sen AI Peng-Fei FAN Key Laboratory of Forest Disaster Warning and Control in Yunnan Province Southwest Forestry University Institute of Eastern-Himalaya Biodiversity Research Dali University Gaoligongshan National Natural Reserve

In this study, the quadrat method was used to study the effects of tsaoko （Fructus tsaoko） plantation on tree diversity and canopy structure of two natural habitats of eastern hoolock gibbon （Hoolock leuconedys）： Nankang （characterized by extensive tsaoko plantation） and Banchang （relatively well reserved and without tsaoko plantation）. Totally, 102 tree species from 25 families and 16 woody liana species from 10 families were recorded in Nankang, whereas 108 tree species from 30 families and 17 woody liana species from 12 families were recorded in Banchang. Although the tree species between two habitats is different, both habitats are characterized by enriched food resources for eastern hoolock gibbons, sharing similar dominant plant families. Due to tsaoko plantation, tree density proportion and diversity of forest layer I （〉20 m） in Nankang were both significantly decreased, but the tree density of layerH （10-20 m） increased. Likewise, in conjunction with these behavioral observations, we also address potential impacts of tsaoko plantation on the behavior of eastern hoolock gibbon.

Social organization of Shortridge’s capped langur（Trachypithecus shortridgei） at the Dulongjiang Valley in Yunnan,China

引用

Zoological Research 2015年第3期36卷 152-160页

作者： Ying-Chun LI Feng LIU Xiao-Yang HE Chi MA Jun SUN Dong-Hui LI Wen XIAO liang-wei cui Forestry Faculty Southwest Forestry University Kunming Yunnan 650224 China Nujiang Administration Bureau Gaoligongshan National Nature Reserve Liuku Yunnan 673100 China Institute of Eastem-Himalaya Biodiversity Research Dali University Dali Yunnan 671003 China College of Life Sciences Northwest University Xi'an 710069 China

Non-human primates often live in socially stable groups characterized by bonded relationships among individuals. Social organization can be used to evaluate living conditions and expansion potential. Bisexual group size, ratio of males to females and group composition are essential elements determining the type of social organization. Although the first report on Shortridge’s capped langurs（Trachypithecus shortridgei） was in the 1970 s, until now, the species only inhabits forests of the Dulongjiang valley in northwest Yunnan, China, with c. 250-370 individuals in 19 populations. To understand its social organization, we collected data from five groups of Shortridge’s langurs at Silaluo in the Dulongjiang valley during August 2012-October 2013. Family groups consist of one adult male, 2–3 adult females and up to five young. Group size averaged 8（7-9） individuals. The ratio of adult males to females（M/F） was 1：2.9, infants to adult females was（I/F） 1：2.2; and ratio of adults to immatures was 1：1.2, indicating the potential of a population increasing. Birth season was during March-July and the inter-birth interval was two years.

Birth seasonality and pattern in black-and-white snub-nosed monkeys （Rhinopithecus bieti） at Mt. Lasha, Yunnan

引用

Zoological Research 2014年第6期35卷 474-484页

作者： Jin-Fa LI Yu-Chao HE Zhi-Pang HUANG Shuang-Jin WANG Zuo-Fu XIANG Juan-Jun ZHAO Wen XIAO liang-wei cui Key Laboratory of Forest Disaster Warning and Control in Yunnan Province Southwest Forestry University Kunming Yunnan 650224 China Bureau of Yunling Provincial Nature Reserve Lanping Yunnan 671400 China College of Life Science and Technology Central South University of Forestry and Technology Changsha Hunan 410004 China Institute of Eastern-Himalaya Biodiversity Research Dali University Dali Yunnan 671003 China

Seasonal variation in environmental factors is vital to the regulation of seasonal reproduction in primates. Consequently, long-term systematic data is necessary to clarify the birth seasonality and pattern of primates in highly seasonal environments. This study indicated that black-and-white snub-nosed monkeys （Rhinopithecus bieti） at Mt. Lasha exhibited strict birth seasonality with a pulse model. Infants were born with a certain degree of synchronization. Birth distribution showed three birth peaks, and the birth pattern showed a ＂V＂ style in even-numbered years and a gradual increase in odd-numbered years. The beginning date, end date and median birth date were earlier in even-numbered years than those in odd-numbered years. The higher latitude of their habitats, earlier birth date, shorter birth period, fewer birth peaks and stronger birth synchrony might be adaptations for strongly seasonal variation in climate and food resources. After the summer solstice when daylight length began to gradually shorten, R. bieti at Mt. Lasha started to breed during the period with the highest environmental temperature and food availability, which implied that photoperiod may be the proximate factor triggering the onset of estrus and mating. It appears that R. bieti coincided conception and mid-lactation with the peak in staple foods, and weaning with the peak in high quality of foods. Thus, food availability was the ultimate factor regulating reproductive seasonality, and photoperiod was the proximate factor fine-turning the coordination between seasonal breeding and food availability.

在分布源(包括相干分布源和非相干分布源)的二维波达方向估计中,均匀圆阵由于可实现全方位测角、具有较高的分辨率,得到了广泛的应用,然而现有的估计算法均需要谱峰搜索和特征值分解,复杂度较高.针对此问题,考虑单个相干分布源或非相干分布源入射两种情况,提出了一种基于矢量化差分相位的解耦二维波达方向快速估计算法.该算法首先基于空间频率近似模型,证明了任意单个分布源入射时,均匀圆阵中不同阵元接收信号间的差分相位均不受角度扩展参数的影响;基于此特性,通过获取差分相位即可实现中心波达角的解耦合;接下来,提取采样协方差矩阵的严格上三角元素相位,即对应于各阵元间的差分相位,并进行矢量化处理,最终将波达方向估计问题转化为一个最小二乘问题,从而直接得到闭式解,避免了谱峰搜索和特征值分解运算,大幅度降低了复杂度.理论分析和仿真实验表明,所提算法具有较高的估计精度,并且无需角信号分布的先验信息,同时具备较低的计算复杂度和硬件复杂度,有利于复杂环境下阵列测向等工程实践.
