云南白马雪山自然保护区猕猴和滇金丝猴的生态位分离(英文)

原则上,食叶的滇金丝猴(Rhinopithecus bieti)和杂食的猕猴(Macaca mulatta)是可以同地共栖的,但这两种灵长类究竟是如何同地共存却一直是一个鲜见涉足的问题。该文初步通过分析它们的食性和生境需求来阐明两者共存的可能性。在猕猴取食约22种植物中,有16种也是滇金丝猴的取食对象。两种灵长类都显示出喜食果实。人们尚未发现滇金丝猴涉足人类作物等相关资源,但发现猕猴经常侵食庄稼。这与其生活海拔不同有关:滇金丝猴一般生活在平均海拔为3218m的山林中,而猕猴活动在平均海拔为2995m的林地。猕猴也会涉足牧场,而滇金丝猴回避这种场地。对于这两个种,混合的落叶阔叶/针叶林是最频繁使用的森林类型;滇金丝猴很少进入常绿阔叶林(青冈属群落,利用率仅3%),而猕猴相对进入这类林型的机会远比滇金丝猴高(36%)。两个物种的群体间常相互远离(2.4km)。当其相遇时,常是猕猴主动回避。上述结果提示滇金丝猴和猕猴是通过大生境分化利用和空间避让来共存的。尽管不同的生境利用策略一定程度上会反映种间竞争的存在,但这种不同更可能反映着它们不同的生理/生态需求。     

金丝猴躯干骨及四肢骨的研究

金丝猴(Rhinopithecus roxellanae Milne-Edwards)仅产我国,是闻名世界的稀有珍贵动物之一。有关金丝猴形态学的研究,国外由于材料之难得而研究甚少,Hill(1966)的《灵长类的比较解剖学和分类学》专著中对金丝猴属亦仅在分类和分布上作了简述;即使国内,以往亦多偏重于外部形态及生态生物学的观察研究,而对其内部系统解剖方面亦报道不多。近年来,我们进行了金丝猴的一些系统解剖工作,本文仅将在研究其躯干骨和四肢骨的基础上,同时与黑叶猴(Presbytis francoisi Pousa-rgues)和猕猴(Macaca mulatta Zimmermann)进行对比,以期阐明其结构特点和与后二者的差异,为丰富其系统形态学的内容积累资料,亦为进一步探讨其分类地位提供依据。     

现生太行山猕猴与猕猴化石骨指数的比较

为探讨现生太行山猕猴与猕猴化石骨指数的差异,对太行山猕猴与广西崇左早更新世猕猴化石的肢间指数(Intermembral index,IM)、臂指数(Brachial index,BI)、股指数(Crural index,CI)和股骨粗壮指数(Robusticity index,RI)等指数进行比较。结果表明,猕猴化石IM值(96)高于太行山猕猴,BI值(94.5)和CI值(88.5)均低于太行山猕猴,推测该猕猴化石在早更新世时期可能地栖生活,适合于陆地四足行走,同时也验证了太行山猕猴主要为半树栖生活。结合对猕猴化石伴生哺乳动物习性的分析,推测广西崇左早更新世的气候温暖潮湿并有一定的水域,植被以森林和灌木为主,有局部的草地或草坡,其自然环境非常适宜高等灵长类生息繁衍。     

川金丝猴

正川金丝猴(Rhinopithecus roxellana),旧大陆的狭鼻猴类,是我国特有的珍稀濒危灵长类,为国家Ⅰ级重点保护野生动物。川金丝猴是典型的森林树栖灵长类,常年栖息于海拔1 500~3 000 m的森林中。图中是分布在我国陕西佛坪境内的大坪峪种群的一只成年雄性(10岁以上),在2015年新组建家庭单元(OMU)。     

中国现生六种非人灵长类和树鼩大脑两半球不对称性的比较研究

对中国现生六种灵长类动物：懒猴、猕猴、灰叶猴、川金丝猴、滇金丝猴、长臂猿以及与灵长类关系密切的树鼩的大脑两半球形态,功能的不对称性以及由此引起的行为不对称性进行了研究。结果表明：大脑两半球不对称现象均存在于上述几种动物中。因而,这种不对称性可能经历了一个长期演化历程。     

金丝猴生齿序和年龄关系的研究

灵长类中根据牙齿的萌出情况和换齿序来确定年龄的研究国内较少。曾中兴等1965在“猕猴精巢发育的研究”中顺带谈到换齿序和年龄的关系,1980年又在“猕猴乳齿的发育”文章中提到乳齿发育与年龄关系。国外研究较多,如赫尔曼(Hurme)、詹姆斯(James)等,对猕猴的出齿序和年龄关系均有论述。肯尼(Kenney),又将前几位学者的工作进行了综述并有所推进。金丝猴(Rhinopithecus roxellanae)的出齿序和年龄的关系,则尚未见有报道。本文目的就是根据我国珍稀动物金丝猴的资料(牙齿:     

云南拉沙山滇金丝猴的种子传播

灵长类是森林中重要的种子传播者,其行为对于森林植物的更新具有重要的生态意义.虽然大量国外科学家关注了灵长类的种子传播行为,但我国的灵长类种子传播研究依然处于起步阶段,这不利于厘清我国灵长类的种子传播行为特点.本研究以云南拉沙山为研究地,关注滇金丝猴对果实性植物的取食及其对种子的传播作用,通过在夜栖地和午休地收集粪便分析灵长类的种子传播特点.结果表明:滇金丝猴共取食9科14种果实性植物,其中蔷薇科植物相对较多,共有6种,占所有植物种类的42.86%.果实特征影响着滇金丝猴的食物选择,滇金丝猴偏好选择肉质果植物和红色果实植物,分别有12种和8种,各占总数的85.71%和57.14%.不同类型的栖息地中,滇金丝猴粪便排放的种子有所差异,75%的种子被排放至夜栖地,仅有25%被排放至午休地.在夜栖地中,大量完整的蔷薇科植物种子被滇金丝猴排放至冷杉林中,这对于某些阔叶树种子在冷杉林中更新至关重要.本研究初步证实了滇金丝猴作为种子传播者在生态系统植物更新中的重要作用.     

中国猕猴生态学研究进展

中国的灵长类学研究始于19世纪中期之后,而兴盛于20世纪80年代至今。猕猴（Macaca mulatta）是世界及中国分布最为广泛的一种非人灵长类动物,在中国境内分布于17个省（市、区）,已被列为国家二级重点保护野生动物。迄今为止,学者们已对猕猴进行了包括地理分布、种群动态、食性、社会生态、保护生态等多方面的研究。本文拟对国内有关猕猴生态学方面的研究工作进行回顾与综述,以期通过对以往工作的汇总,梳理关于猕猴的研究线索与动态,并对今后的研究有所启示。     

秦岭川金丝猴对高海拔栖息地的某些生理适应

金丝猴是我国特有的灵长类,也是海拔分布最高(4 167m)的灵长类,从生理生态学角度研究金丝猴怎样适应高寒山区的生活,具有重要的科学意义．依据十几年的研究结果,并结合已发表的相关资料,从消化、呼吸、血液、循环、生殖几个方面探讨了金丝猴的指名亚种——川金丝猴对秦岭高海拔栖息地的适应及适应机制     

太行山猕猴颅容量与颅骨其他变量的相关性研究

在现生哺乳动物中,灵长类不仅因为其行为机制的复杂性,更因其与人类的近缘性,而受到诸多研究领域的重视。其生存的第一需要就是取食,不同的食物特性总是与头颅的形状变化有关系(Ｓｈｅａ,1983),而颅形的变化必然会与颅容量或脑的体积变化相联系。有关的研究在太行山猕猴尚属空白。太行山猕猴目前仅分布于太行山南段和中条山部分地区,是目前我国分布最北的野生猕猴种群。初步研究表明,太行山猕猴在形态生态行为和遗传等方面与其他亚种均有明显差异(宋朝枢等,1996;薛德明等,1998)。基于保护其生物多样性的考虑,本文对太行山猕猴颅容量与颅骨其…     

Brief communication: Paleobiological inferences on the locomotor repertoire of extinct hominoids based on femoral neck cortical thickness: The fossil great ape hispanopithecus laietanus as a test-case study

The relationship between femoral neck superior and inferior cortical thickness in primates is related to locomotor behavior. This relationship has been employed to infer bipedalism in fossil hominins, although bipeds share the same pattern of generalized quadrupeds, where the superior cortex is thinner than the inferior one. In contrast, knuckle‐walkers and specialized suspensory taxa display a more homogeneous distribution of cortical bone. These different patterns, probably related to the range of movement at the hip joint and concomitant differences in the load stresses at the femoral neck, are very promising for making locomotor inferences in extinct primates. To evaluate the utility of this feature in the fossil record, we relied on computed tomography applied to the femur of the Late Miocene hominoid Hispanopithecus laietanus as a test‐case study. Both an orthograde body plan and orang‐like suspensory adaptations had been previously documented for this taxon on different anatomical grounds, leading to the hypothesis that this fossil ape should display a modern ape‐like distribution of femoral neck cortical thickness. This is confirmed by the results of this study, leading to the conclusion that Hispanopithecus represents the oldest evidence of a homogeneous cortical bone distribution in the hominoid fossil record. Our results therefore strengthen the utility of femoral neck cortical thickness for making paleobiological inferences on the locomotor repertoire of fossil primates. This feature would be particularly useful for assessing the degree of orthograde arboreal locomotor behaviors vs. terrestrial bipedalism in putative early hominins.

北京发现凤头鹰和黑翅鸢

报道了凤头鹰(Accipiter trivirgatus)和黑翅鸢(Elanus caeruleus)2个北京鸟类分布新记录。以上鸟类未见于《北京鸟类志》、《北京脊椎动物检索表》等文献记载。《中国鸟类分布与分类名录》上所列其分布区中也不包括北京。以上鸟类是北京地区近年来新记录到的猛禽。     

Primates in northern Viet Nam: A review of the ecology and conservation status of extant species,with notes on pleistocene localities

We discuss the distribution of living and fossil primates in northern Viet Nam, integrate new localities into the known ranges, and address the ecological parameters and status of extant primate species. In addition, we interpolate fossil specimens from Pleistocene cave sites into the discussion of current ranges. This approach provides a unique glimpse into the past ranges of extant species in a tropical setting, which is unavailable for most regions of the world. Finally, we review the effects of ecocide and other anthropogenic threats to nonhuman primates in Viet Nam.

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.     

A statistical analysis of the literature on sexual dimorphism in primates

The annotated bibliography on sexual dimorphism in primates compiled by the authors was analysed considering the distribution of entries by keytitles, keywords, kind of periodicals and years of publication. A growing interest in this field was observed especially since the 1970s, but a relative scarcity of basic methodological papers was found. Articles on extant human populations and on living nonhuman primates are much more frequent than works on fossil primates and ancient humans.     

Birth of the Japanese Monkey (Macaca fuscata) infant following in-vitro fertilization and embryo transfer

The first successful birth by in-vitro fertilization (IVF) and embryo transfer (ET) in the Japanese monkey was described. IVF was carried out by using oocytes collected after ovarian stimulation and sperms collected by rectal electro-ejaculation. The embryos were incubated for 36–66 hours and then transferred to the fallopian tube of the recipient via the fimbria under laparoscopic observations. Four recipients received their own embryos and six recipients received donor embryos. Two recipients of six that received donor embryos became pregnant after receiving one 3-cell and one 2-cell embryos, and one 4-cell and one 2-cell embryos, respectively. On healthy terminated male infant was delivered 166 days after ET, but the other aborted on day 128. This successful birth indicates the usefulness of our IVF/ET method for systematic indoor artificial breeding and preservation of endangered primates species.     

Permineralized rhizomes of the Osmundaceae (Filicales): Diversity and tempo-spatial distribution pattern

The family Osmundaceae is among the most primitive ferns of the Filicales, with an extensive fossil record dating back to the Late Paleozoic. Numerous fossil osmundaceous rhizomes have been documented in the geological history. However, the diversity, variation and distribution pattern of permineralized rhizomes remain poorly known. Here we intend to analyze the fossil records with regard to the diversity and distribution pattern of the osmundaceous rhizomes based on available data. To date, about 83 species ascribed to 14 genera of fossil osmundaceous rhizomes have been described worldwide, assigned to two subfamilies, namely, Thamnopteroideae and Osmundoideae. Geologically, two groups (i.e., Thamnopteroideae and Palaeosmunda) have been reported in the Permian. All the Triassic taxa are from the southern hemisphere. Jurassic osmundaceous rhizomes are abundant and widespread throughout the world, most dominant in the southern hemisphere. During the transition of Jurassic to Cretaceous, the diversity of osmundaceous rhizomes declined rapidly. In the Cretaceous, however, the osmundaceous rhizomes from the northern hemisphere surpass those from the southern hemisphere in generic level for the first time. The Cenozoic taxa diversified in the northern hemisphere with the rise of angiosperms. Geographically, the osmundaceous fossil rhizomes have been found in both hemispheres; the major localities include Ural area of the former USSR, Tasmania of Australia, southern Argentina, Antarctica, northern India, central and western part of North America and northern China. We discuss the origin, radiation, and development of the Osmundaceae based on rhizomes, to help further understand the systematic relation and evolutionary history of the family Osmundaceae.
