太行山猕猴的食性

猕猴 (Ｍａｃａｃａｍｕｌａｔｔａ)是世界上地理和生态地位分布最广泛的非人灵长类。我国是唯一的地跨热带、亚热带、暖温带均有猕猴分布的国家。直到1987年 ,亚洲最北部的猴群在河北兴隆绝灭以后[12 ] ,自然分布于河南省与山西省交界处的太行山及中条山南段的猕猴就成为亚洲猕猴分布的最北界 ,位于Ｎ35°11'～ 35°17',Ｅ112°0 3'～ 112°33',地处暖温带。经 1981年以来的调查研究发现 ,太行山猕猴在形态、生理、生态等方面与其它地区的猕猴不同 ,是最具研究意义的种群[5] 。猕猴同其它动物一样 ,通过食物与其它动物 ,周围环境及人类物质…

野生太行山猕猴的社会结构

2009年2月至2010年7月,在河南太行山猕猴国家级自然保护区济源管理局所辖的天坛山管护区,基于个体识别和野外跟踪,观察了一个野生太行山猕猴群(王屋1群, WW-1)的社会结构,采用随机取样法(Ad libitum sampling)记录了该群内成年个体之间、母系单元之间的竞争行为过程,进而依据"David得分法"构建了WW-1群内成年个体及母系单元间的优势等级, 并采用瞬时扫描取样法(Instantaneous andscan sampling)记录了成年个体到达投食区的移动顺序, 分析了平均移动序位与社会顺位的相关性。结果表明: 1)WW-1群体大小为41只个体, 由7个成年雄性和13个成年雌性以及21个未成年猕猴组成, 群内的成年雌性个体分别隶属于3个母系单元; 2)群中成年雄性、成年雌性、亚成年雄性、亚成年雌性、青少年雄性、青少年雌性、婴幼猴雄性、婴幼猴雌性的比例为1∶1.86∶0.29∶0.43∶0.86∶1.29∶0.14∶0, 且未成年个体占全群的51.2%; 3)WW-1群表现出严格的优势等级结构, 成年个体优势顺位由高到低依次是: 豁鼻>次红>白鼻>痞子>红脸>尖脸>小白脸>皱眉>光鼻>长毛>黑颊>小不点>斑点>斑眼>灰头, 母系单元间的优势顺位由高到低依次是红脸单元>长毛单元>斑点单元。研究结果提示, 太行山猕猴的社会结构为多雄多雌型; 成年雄性个体之间优势等级较成年雌性严格, 而成年雌性的社会顺位受所在母系单元社会顺位的影响; WW-1群的α位为成年雄性, 其在获取资源上具有优先性。

Bone Marrow Depletion as a Coincidental Finding to Hypothermia in Macaca mulatta

Three of 16 juvenile rhesus monkeys (Macaca mulatta) and 1 rhesus of 79 adult rhesus and cynomolgus monkeys (Macaca fascicularis) were found comatose in a state of profound hypothermia after a heating failure occurred in the room in which they were housed. One juvenile monkey died shortly thereafter. The three other monkeys were revived with gradual warming and supportive therapy but later experienced separate acute clinical crises manifesting shock and died at 19, 31, and 51 days after the initial episode. Histopathologic findings of severe bone marrow depletion were observed in each of the three monkeys that died after the initial episode.     

太行山猕猴掌骨性别判别分析

为了了解成年太行山猕猴5根掌骨的性差大小。本文对太行山猕猴掌骨标本40例(雄:10, 雌:30)进行观察并选择掌骨的9项形态变量进行测量。数据用SPSS19.0软件进行多变量判别分析。结果表明: 5根掌骨长度等变量在性别之间有明显差异。用全模型法5根掌骨的性别正确判别率范围为94.1%~100.0%, 用逐步判别法掌骨性别正确判别率范围为93.8%~97.5%。有关掌骨的9个形态变量, 长度变量首先被挑选出来, 说明在性别判别中起重要作用。分别用左右侧掌骨的判别函数来判别性别时侧别差异不明显。结论: 用每根掌骨的形态变量建立判别函数可以有效地区分性别, 对非人灵长类掌骨标本的性别鉴定有一定的理论意义和应用价值。     

南京红山森林动物园猕猴的社会玩耍行为

社会玩耍行为是灵长类动物的常见行为类型之一,作为种群数量最大的非人灵长类之一,猕猴(Macaca mulatta)的社会玩耍行为是它们日常生活的一部分。本研究利用红外摄像技术,对南京红山森林动物园猕猴冬季社会玩耍行为的基本特征进行了研究。研究记录了每一回合玩耍行为的发生时间、持续时间、参与对象年龄、参与个体数以及玩耍行为类型等行为参数。在持续10 d的视频中,共记录到猕猴的社会玩耍行为7 496次,其中触摸和抓打4 018次,追逐1 012次,撕咬和摔跤671次,其他53次,以及各种玩耍行为组合1 742次。利用单因素方差分析,发现猕猴的社会玩耍行为节律明显,两个玩耍高峰分别为08:30~09:30时和10:30~11:30时。利用Kruskal-Wallis检验及Mann-Whitney U两两比较法,发现参与个体数和玩耍行为类型对社会玩耍持续时间影响显著,在玩耍过程中,参与个体数越多,社会玩耍持续时间越长;组合类型的持续时间最长,其次是撕咬和摔跤,再次是触摸和抓打,最后是追逐。0~3岁的少年个体在玩耍行为中更常采用触摸和抓打类型,而亚成年及成年个体则倾向于选择追逐类型。该研究量化了猕猴社会玩耍行为的类别和影响因素,为动物园的猕猴管理和动物福利提供了数据支持。     

雌激素受体在老年和青年猕猴下丘脑中表达的比较

为了观察老年猕猴下丘脑中雌激素受体的表达及变化情况,运用免疫组织化学SABC 法,对青年和老年猕
猴下丘脑雌激素受体的表达特点进行了研究。结果发现,雌激素受体免疫阳性细胞主要分布于下丘脑的室周灰
质、室旁核、腹外侧核、腹内侧核、弓状核等,雌激素受体阳性产物主要定位于细胞核和细胞质中。与青年猕
猴比较,老年猕猴下丘脑各个核团的雌激素受体在表达强度及阳性细胞数量上均显著或极显著低于青年猕猴
(P<0.05 或 P<0.01)。表明,老年猕猴下丘脑雌激素受体的表达显著低于青年猕猴,可能为老年猕猴雌激素缺
乏所致。

Urinary cyclic AMP excretion is increased in Macaca fascicularis and Macaca mulatta compared to humans

Changes in parathyroid hormone and its second messenger cyclic AMP have been implicated in the pathogenesis of osteoporosis. Nonhuman primate models have been useful in the study of osteoporosis, but the physiology of mineral metabolism in certain species is different than in humans. We investigated parameters of mineral metabolism in 15 normal adult female cynomolgus and 14 normal adult female rhesus monkeys. In both species, urinary cyclic AMP was increased compared with humans, and the nephrogenous cyclic AMP in the cynomolgus monkeys was also elevated. Despite this, there was no evidence for hyperparathyroidism in either species as evaluated by serum or plasma phosphorus and midregion-specific and/or aminoterminal-specific immunoreactive parathyroid hormone. Given the increasing use of nonhuman primates in the study of osteoporosis, understanding basic changes in mineral metabolism is important before pathologic effects of bone loss can be understood.     

Mandibular growth in the rhesus monkey (Macaca mulatta)

Mandibular growth of 42 rhesus monkeys (Macaca mulatta) was analyzed quantitatively and qualitatively. Four groups of animals were defined according to dentitional age (i.e., infant, juvenile, adolescent, young adult). At each age growth was observed for a 24 week period. Since some animals were observed at more than one stage of development, 57 periods of growth were studied. The growth incremental data were collected by superimposing serial cephalograms on mandibular implants. Growth and remodeling of both the skeletal and dento-alveolar components of the rhesus mandible were greatest in the infant monkeys and were less in successive age groups. Posterior relocation of the ramus was noted in all age groups while bone deposition on the anterior and inferior borders of the mandibular body was greatest in the younger animals. The most pronounced dental changes also occurred in the younger animals while the dentitions of the adolescent and adult animals were generally more stable. This study demonstrates that the rate and direction of normal mandibular growth varies with the age of the animal. Furthermore, mandibular growth is quantified at four defined maturational levels to provide a set of values illustrating normal mandibular growth. These values can also be used as control data for experimental studies.     

The density of long limb bones and the percentage ash weight of the skeleton of Macaca mulatta

The gravimetric density of humeri, radii, femora and tibiae from a series of 274 male and female skeletons of rhesus monkeys, Macaca mulatta, was determined for fetal, young and adult periods. The ages of 171 of the animals were known: they ranged from 57 days of gestation to 13.6 years; the ages of an additional 103 skeletons were estimated. The mean density of the fetal bones was found to increase linearly with age and was higher for males than females, and higher for the superior than for the inferior limb bones. During the young period the pattern of increase in density can be represented by a power-type curve, and the density is significantly higher in females than in males and in superior than in inferior limb bones. The densities of the long limb bones of the adult skeletons show a slight, but not significant, negative trend with increasing age. In this age group the mean densities are higher for males than females and higher for the superior than for the inferior limb bones. The percentage ash weight was determined for the total skeleton and for 21 subdivisions of 23 postnatal skeletons with estimated ages. The skull and long limb bones were found to have higher mean percentage ash weights than the vertebral segments and the sternum. Both the density and the percentage ash weight of the Macaca mulatta skeletons examined exceed those found in our earlier studies of the human skeleton.     

Growth of the maxillary complex in the rhesus monkey (Macaca mulatta)

The growth of the maxillary complex of 36 rhesus monkeys (Macaca mulatta) was analyzed quantitatively and qualitatively during four defined stages of postnatal development (i.e., infant, juvenile, adolescent, young adult). At each stage, growth was observed during a 24 week period. Since some animals were observed during two successive stages of development, 47 periods of growth were studied. The incremental growth data were collected by superimposing serial cephalograms on cranial base implants and on maxillary implants. The largest increments of growth were observed in the infant animals and were successively less during the other periods studied. The horizontal growth component was more prominent than the vertical component in all age groups. The contribution of sutural growth to the vertical displacement of the maxilla was greater posteriorly, leading to a rotation of the maxillary complex during growth. The occlusal relationship was maintained by selective bone remodeling in conjunction with dentitional migration.
