金丝猴(Rhinopithecus)消化系统的主要特征

在疣猴科种类的消化系统研究中,Ayer（1948）对亚洲的长尾叶猴和Hill（1952）对非洲的橄榄疣猴作了较详细的研究。至于中国的金丝猴,除了本文作者（1983）对胃作了研究外,尚无其他报道。本文就金丝猴消化系统的主要特征报道于后,并与有关种类作了比较。     

白头叶猴婴猴月龄和性别对母婴关系的影响

非人灵长类动物的母婴关系是婴猴第一次重要的社会体验,对婴猴的生长发育、正常社会行为以及心理健康都具有重要意义。因此,母婴关系研究一直是灵长类学研究的热点之一。为深入了解白头叶猴(Trachypithecus leucocephalus)母婴关系的发展和影响因素,2009年9月至2010年8月,我们以广西崇左白头叶猴国家级自然保护区岜盆片区的一群野生白头叶猴为研究对象,记录其母婴行为的发生持续时长和发生频次,结合婴猴月龄和性别,探究婴猴月龄和性别对白头叶猴母婴关系的影响。结果表明：婴猴月龄显著影响白头叶猴的母婴关系。随着婴猴月龄的不断增长,母猴对婴猴的保护也随之逐渐减少,表明婴猴的发育是从依赖母猴到逐步独立融入社群的过程。婴猴性别对母婴行为的持续时间无显著影响,但在发生频次上母猴对雌性婴猴的照顾明显多于雄性婴猴。婴猴性别对母婴间的理毛行为、含乳行为均无显著影响,但对怀抱行为具有显著影响。白头叶猴母猴对不同性别的婴猴采取不同的照顾方式,这可能与雄性婴猴和雌性婴猴未来所承担的社会角色不同有关。     

野生川金丝猴一个全雄青年猴群的同性爬背行为

本研究采用行为取样方法,首次对秦岭野生川金丝猴全雄青年群中的同性爬跨行为进行报道。研究中我们共观察到21 次同性爬背行为,其平均持续时间为5.53 ± 3.11s;雄性同性爬背发生前的行为中以玩耍行为(47.62% )和3 种不同姿势的邀配模仿行为(42.85% )为主;而同性爬背行为发生后则主要为彼此间的相互理毛行为(47.62% )和玩耍行为(23.81% )。对比先前婴幼猴时期的相关研究结果,青年猴同性爬背行为前邀配模仿资势的多样化在一定程度上体现了野生状态下雄性川金丝猴个体青少年阶段的性行为发育进程。考虑到川金丝猴全雄群的社会结构,青年猴同性爬背行为具有巩固社群稳定和加强个体关系的功能。此外,研究中观察到76.19% 的同性爬背行为发生在昼间休息期之后的第一个小时内,这可能是“睡眠与觉醒循环”对性激素的反调节作用所致。     

秦岭川金丝猴长时间携带死婴行为

本文首次报道了一例秦岭川金丝猴死婴被其母亲和近亲未成年雌猴长时间携带行为。携带者的行为除正常婴猴中常见的检视、嗅吻、理毛行为外,还有嘴叼和手抓携带行为,后者是正常婴猴携带行为中未曾见到过的。对于树栖生活为主的川金丝猴,与正常婴猴相比,死婴的携带更加困难,母亲对死婴的行为方式在一定程度上体现了对婴猴的母爱和照料能力。本文对死婴携带行为发生的原因及其意义进行了初步探讨。     

叶猴(Presbytis)、金丝猴(Rhinopithecus)、长臂猿(Hylobates)自由取食时的利手现象

本文报道叶猴、金丝猴、长臂猿自由取食时的利手现象。本研究共用金丝猴12只(雄性8只,雌性4只),叶猴25只(雄性16只、雌性9只),长臂猿5只(雄性3只,雌性2只)。对每个动物而言,总观察次数不少于30次,其结果显示:在雄性金丝猴中,62.5％的动物显示右利,25％显示主利,12.5％无利手现象。在雄性叶猴中,62.5％的动物显示右利,18.7％显示左利,18.7％无利手现象。在3只雄性长臂猿中,2只显示右利,一只无利手现象。 统计结果表明:雄性金丝猴有明显的右利手现象(P<0.05),雄性叶猴右利手现象接近显著(P=0.06),长臂猿因观察数量太少,未进行统计。 在上述三种动物中,雌性个体无利手现象。 木工作结果提示:(1)雄性金丝猴,叶猴在自由取食时具有右利手现象,长臂猿也可能有右利手现象,(2)大脑两半球的不对称性与性别有关。     

饲养条件下川金丝猴群中主雄的移除和替换对社群行为的影响

在上海野生动物园对一群半散养的川金丝猴进行了为期一年的行为学研究。在此期间,猴群中发生了4起家庭主雄被移除和替代事件和一个雌性群因繁殖需要引入一个成年雄猴的事件,该过程在饲养条件下首次被完整记录。观察发现,繁殖群中,在家庭主雄猴的健康状况良好期间,群中各雄性成员间的社会等级关系相当稳定,很少变动。主雄猴有效地控制着群体的秩序,并严格地看护着其家庭中的雌猴免受其他雄猴的侵扰,而且它也很少对其他低序位雄猴主动攻击。全雄群中则再由一个高序位雄猴控制其他低序位雄猴。疾病、衰老、前主雄猴的存在以及被饲养人员从群中移除进行治疗等都可能引起猴群社会发生很大动荡,尤其是全雄群中各雄猴的社会等级序位发生剧烈改变,甚至发生家庭主雄的替代。在本报道中,人为因素在主雄替代过程中起着主要作用。主雄替代一旦成功,新主雄会把原主雄赶入全雄群,攻击追撵其他低序位雄猴,并彻底与全雄群完全脱离。对于每一个新主雄,家庭中的雌猴对其的接纳表现出明显的选择倾向。雌性性选择可能是野生猴群中新家庭群建立一种内在基础机制,同时提示偷配发生的可能性。     

神农架川金丝猴投食群的母婴关系

灵长类动物母亲的育婴行为不仅对后代的存活起着关键作用,而且对婴猴的发育和成年后的社会交往有着重大影响,因此母-婴关系一直是灵长类学研究的热点之一。为了解川金丝猴的母-婴关系,探讨川金丝猴母-婴关系个体差异的影响因素,我们于2013年3月至2014年10月,以母-婴间相对距离表示照料强度,对神农架川金丝猴的母-婴照料关系以及母亲照料强度个体差异的影响因素进行了定量研究。结果表明：母亲照料行为强度、母亲对阿姨行为的容忍与婴猴年龄相关,限制行为与婴猴年龄不相关。身体接触与婴猴年龄不相关;腹部接触以及母-婴相对距离小于1 m与婴猴年龄呈负相关;相对距离1 m至5 m、相对距离5 m至10 m和相对距离大于10 m与婴猴年龄呈正相关;母亲对阿姨行为的拒绝与婴猴年龄呈负相关;母亲对婴猴的限制行为与年龄不相关。总的来说,即随着婴猴成长,母婴间距离越来越远,母亲也逐渐减少对婴猴的保护。母亲的生育经验、婴猴性别、婴猴出生先后和社会单元大小对神农架川金丝猴母婴关系没有显著影响,补食群丰富的食物资源和群内雌性友好的关系可能是导致本结果的原因。     

滇金丝猴和川金丝猴的面肌

本文是金丝猴面肌的首次记述。与疣猴亚科和猴亚科的任何种类相比,全丝猴面肌中最有趣的结构是存在着笑肌成分,虽然还未分化成一独立的肌。在全部猴科动物中,这是至今未被发现过的。文中还与其它种类,特别是叶猴作了比较。     

生态旅游活动中游客噪声对滇金丝猴的影响

生态旅游被视为解决保护和发展的最有效手段之一,但现阶段的生态旅游开展对野生动物造成影响的程度和方式还缺乏研究。为研究生态旅游活动开展过程中产生的噪声是否会对滇金丝猴（Rinopithecus bieti）产生影响,2017年7月5日至2018年2月8日,在云南香格里拉滇金丝猴国家公园,采用10 min间隔的瞬时扫描取样法记录游客噪声、观赏距离、可见滇金丝猴总数量及其不同年龄-性别组滇金丝猴个体数量。结果显示,生态旅游行为显著增加了环境噪声值,向游客开放时段的噪声值（52.42 dB）显著高于非开放时段（47.51 dB）,且游客数量越多噪声值越大;游客的观赏距离越近可见的滇金丝猴个体数量越少,且不同观赏距离下可见的滇金丝猴个体数存在显著差异,当观赏距离在11 ~ 15 m时,游客可见滇金丝猴总数量最多（2 046只）;在1 ~ 5 m的观赏距离内,不同年龄-性别组猴的理论可见数量不同,成年雄性猴的理论可见数量最高（2.9只）,其次是青少年猴（2.2只）,成年雌猴（1.8只）和婴猴（1.6只）最低。推测,不同年龄-性别组滇金丝猴个体抵抗干扰的能力不同,成年雄性猴抗干扰能力最强,其次是青少年猴个体,成年雌性猴和婴猴抗干扰能力较弱。由此,本研究认为,现阶段香格里拉滇金丝猴国家公园的生态旅游活动增加了环境噪声,且对滇金丝猴的行为产生了一定的干扰;游客观赏距离越近、游客数量越多,干扰越大。建议在未来的生态旅游过程中,严格设立游客观赏距离,且观赏距离应在10 m以上;设立标语,提醒游客保持安静,减少噪音,从而减少对滇金丝猴的干扰。     

Intestinal capillariasis in New World monkeys

Two cases of intestinal capillariasis have been identified at necropsy in a squirrel monkey and a capuchin monkey born and raised in captivity. The parasites are described as far as possible from the histopathological slides or intestinal contents, and their relationship to other intestinal capillarids, especially those of primates, is discussed.     

人工饲养恒河猴、食蟹猴的繁殖性能初报

目的探索北京地区人工饲养恒河猴与食蟹猴的繁殖性能,为温带地区猕猴的人工饲养和繁殖方式提供借鉴。方法对军事医学科学院实验动物中心饲养的317只恒河猴繁殖群（30只雄猴,287只雌猴）和78只食蟹猴繁殖群（8只雄猴,70只雌猴）近两年的繁殖性状进行观察和统计分析。结果恒河猴母猴妊娠率、繁殖率和成活率分别为60.73%、54.45%和96.89%。食蟹猴母猴妊娠率、繁殖率和成活率分别为79.86%、56.12%和75.00%。结论食蟹猴和恒河猴可以成功的在温带地区饲养和繁殖,但人工饲养食蟹猴的妊娠率与产仔率较恒河猴高,而仔猴成活率则低于恒河猴。     

高反应与低反应猴在诱发动脉粥样硬化过程中血脂改变规律的观察

喂饲高脂高胆固醇饮食是诱发实验性动脉粥样硬化（简称AS）的基本方法。在诱发AS过程中,血清脂质的改变不但有种属差异,也存在个体反应性的差异。猴是用于AS研究最理想的实验动物。喂以高胆固醇饮食后,有些猴血清胆固醇上升速度明显高于一般同种猴,称高反应猴（High-responding rhesus monkey）;另一些猴的血清胆固醇上升十分缓慢,低于同种猴的一般反应速度,称低反应猴（Low-responding rhesusmonkey）。关于高反应猴（简称HI）及低反应猴（简称LO）在诱发AS过程中血清胆固醇反应的差别,国外已有报道。（Baker et al.,1981;Bhattacharyya et al.,1977;     

Expression of taste signal transduction molecules in the caecum of common marmosets

The extraoral presence of taste signal transduction proteins has recently been reported in rodents and humans. Here, we report for the first time the presence of these signal transduction proteins in the caecum of a non-human primate, the common marmoset. Quantitative RT-PCR data on the gene expression of taste signal transduction molecules (gustducin and TRPM5) in common marmosets suggested high expression in the caecum, which was not observed in other non-human primates. Immunohistochemical analysis confirmed the specific presence of gustducin and taste receptors in marmoset caecal cells. These results may relate to the specific feeding behaviour of marmosets, which consume plant exudates, primarily gums.     

The distribution pattern of rhesus and Assamese monkeys in Nepal

Surveys of the distribution and some ecological characteristics of rhesus monkeys (Macaca mulatta) and Assamese monkeys (M. assamensis) in Nepal were conducted during 234 days in 1976, 1978, and 1984. Rhesus monkeys dominated in the tropical, subtropical, and temperate forests below 3,000 m a.s.l. all over Nepal. Assamese monkeys were patchily distributed along rivers in the tropical and subtropical areas. Both species principally utilized forests parapatrically. The mean troop size of rhesus monkeys (29.5) was significantly larger than that of Assamese monkeys (19.1). Discontinuous distribution of Assamese monkeys probably appeared as a result of the expansion of rhesus monkey distribution in the mid- and late-Pleistocene. Because of small distribution areas and small numbers of monkeys, urgent conservation policy must be pursued.

Comparison of oxime reactivation and aging of nerve agent-inhibited monkey and human acetylcholinesterases

Non-human primates are valuable animal models that are used for the evaluation of nerve agent toxicity as well as antidotes and results from animal experiments are extrapolated to humans. It has been demonstrated that the efficacy of an oxime primarily depends on its ability to reactivate nerve agent-inhibited acetylcholinesterase (AChE). If the in vitro oxime reactivation of nerve agent-inhibited animal AChE is similar to that of human AChE, it is likely that the results of an in vivo animal study will reliably extrapolate to humans. Therefore, the goal of this study was to compare the aging and reactivation of human and different monkey (Rhesus, Cynomolgus, and African Green) AChEs inhibited by GF, GD, and VR. The oximes examined include the traditional oxime 2-PAM, two H-oximes HI-6 and HLo-7, and the new candidate oxime MMB4. Results indicate that oxime reactivation of all three monkey AChEs was very similar to human AChE. The maximum difference in the second-order reactivation rate constant between human and three monkey AChEs or between AChEs from different monkey species was 5-fold. Aging rate constants of GF-, GD-, and VR-inhibited monkey AChEs were very similar to human AChE except for GF-inhibited monkey AChEs, which aged 2-3 times faster than the human enzyme. The results of this study suggest that all three monkey species are suitable animal models for nerve agent antidote evaluation since monkey AChEs possess similar biochemical/pharmacological properties to human AChE.

Parturition in a free-ranging Japanese monkey (Macaca fuscata)

Parturition behavior of a multiparous female and her interactions with group members throughout the birth process were recorded for a free-ranging Japanese monkey (Macaca fuscata). The female showed evidence of 18 contractions during the 35 min prior to delivery, with a mean duration and a mean intercontraction interval of 30 sec and 96 sec, respectively. These values were similar to those in individually caged Japanese monkeys. Some adult females remained in proximity to the female who was giving birth during the prepartum phase, and her 2-year-old daughter watched the delivery of the infant. Even during the prepartum phase the female moved in order to keep up with the group which traveled from the feeding site to a sleeping site in the forest.     

A Flexible Restraint Chair for the Cynomolgus Monkey (Macaca fascicularis)1

We have found that commercial restraint chairs suitable for the rhesus monkey (Macaca mulatta) cause severe physical distress to many cynomolgus monkeys (Macaca fascicularis). A new restraint chair has therefore been designed specifically for the cynomolgus. The key features of the chair are an angled neck piece, a large opening to provide free movement for the tail, a soft waist restraint, and a level surface for both the heels and ischial pads. This new chair is not only suitable for the cynomolgus monkey but may also be more comfortable for the rhesus monkey than standard commercial chairs.
