菲氏叶猴和黑叶猴的齿弓 总被引:4,自引:0,他引:4
本文对菲氏叶猴(Presbytis phayrei)和黑叶猴(Presbytis francoisi)成年头颅的上下齿弓进行了比较研究。结果说明,在黑叶猴中,由于与颧骨眶低点相连,垂直于M~3根部齿弓的距离非常显著地大于菲氏叶猴,因而其面颅体积显著性地大于菲氏叶猴,而且菲氏叶猴的面颅比黑叶猴更为凸出。在对齿弓的对称性研究时发现,除黑叶猴的上齿弓向右偏离外,别的都向左侧发生偏离。这种偏离似乎与用手优势相联系。在进行多变量分析时发现,两种叶猴所研究的变量下颌的比上颌的发生了更大的变异。进一步证实了运动的器官比固定的器官易产生变异。 相似文献

黑叶猴和灰叶猴的线粒体DNA限制性片段长度多态研究 总被引:1,自引:0,他引:1
本文以15种限制性内切酶分析黑叶猴和灰叶猴种内及种间mtDNA多态。从各个样品中分别检出了41—50个酶切位点。综合15种限制内酶的酶切类型,在2只黑叶猴和2只灰叶猴中分别检出了两种限制性类型,并与其4个地理来源相对应。结合恒河猴和红面猴的资料,构建了4种猴科动物的分子系统树。结果表明,黑叶猴和灰叶猴种内的分歧分别始于30和35万年以前,两种叶猴的分离始于190万年以前,猴亚科和疣猴亚科的分离应早于1100万年。叶猴属在中国的扩散不是很晚才发生的。 相似文献

应用荧光原位杂交技术中的染色体涂染法(Chromosomepainting),以生物素标记的除Y染色体外的人全部整条染色体DNA特异性探针与黑叶猴的中期分裂相杂交,建立了人与黑叶猴之间的染色体同源性。除人的1、2、6、16和19号染色体特异探针分别与黑叶猴的2条非同源的染色体杂交外,其余人染色体特异探针均与黑叶猴的1条染色体杂交,其中有两对人染色体特异探针(14和15,21和22)分别杂交同一条黑叶猴染色体。在雌性黑叶猴的单倍染色体中,共检测到30个与人染色体具同源性的染色体和染色体片段。结果表明:黑叶猴的多数染色体与人染色体有高度同源性,仅有少数染色体发生了重排。将研究的结果与已报道的人染色体特异探针与其他灵长类的中期染色体杂交的结果进行比较,可以看出亚洲叶猴之间的相互关系较与非洲叶猴的更为密切。 相似文献

Resource use is known to influence the ranging behaviour of primates, and this effect may be pronounced when the resource is uncommon in the environment. Here we investigate the effect of geophagy on the ranging behaviour of Phayre's leaf monkeys (Trachypithecus phayrei) in the Phu Khieo Wildlife Sanctuary, Thailand. UTM coordinates were collected via GPS from the group centre every 30 min during all-day follows of one study group over a 4-month period. On days during which the group visited a distant saltlick (n = 3), the monkeys travelled significantly further (p < 0.001), significantly faster (p < 0.001) and with fewer stops compared to non-saltlick days (n = 61). Saltlick visits also increased the home range size from 73.7 ha to 93.4 ha. Increased daily path length, increased travel speed and consistent pace are necessary because of the distance from the saltlick to the regularly used portion of the home range, and these reflect the import- ance of soil consumption to the leaf monkeys. 相似文献

The phylogeny of Chinese leaf monkeys, especially the snub-nosed monkeys (Rhinopithecus), has not been thoroughly investigated using molecular sequence data, perhaps due to their rarity in the wild and their poor representation in institutional collections. Despite several proposed classifications, systematic relationships of these species remain poorly defined and this has hindered their conservation. To clarify the phylogenetic relationships of the leaf monkey clade in China, we sequenced the mitochondrial ND3, ND4L, ND4, tRNA

genes for Rhinopithecus bieti, R. roxellana, Trachypithecus francoisi, T. f. leucocephalus, and T. phayrei as well as Pygathrix nemaeus and Colobus guereza. We included a total of 2252 characters for each individual, excluding gaps in primary sequences. Our interpretation of the results from character-and distance-based phylogenetic analyses suggest that (1) Pygathrix nemaeus is sister to Rhinopithecus rather than to Trachypithecus though it is quite divergent from the former; (2) the Yunnan snub-nosed monkey, Rhinopithecus bieti, represents a valid species; (3) the white-headed leaf monkey is not a distinct species, but instead is a subspecies of Trachypithecus francoisi (T. f. leucocephalus), though it should still be considered a separate evolutionary significant unit (ESU); and (4) because two individuals of the Phayrei's leaf monkey, T. phayrei, are genetically distinct from one another, a more extensive revision of the taxonomy of this putative species in China is needed. These results, plus ongoing work on the molecular systematics of the entire Asian leaf monkey radiation, can provide a sound basis for identifying the appropriate units of conservation for this endangered group of primates. 相似文献

Mitochondrial cytochrome b gene sequences of old world monkeys: With special reference on evolution of Asian colobines 总被引:2,自引:0,他引:2
The classification and phylogenetic relationships of the Old World monkeys are still controversial. For Asian colobines, from
three to nine genera were recognized by different primatologists. In the present study, we have sequenced a 424 bp mitochondrial
tRNAThr gene and cytochrome b gene fragment fromMacaca mulatta, Mandrillus sphinx, Mandrillus leucophaeus, Semnopithecus entellus, Trachypithecus vetulus, T. johnii, T. phayrei,
T. francoisi, Pygathrix nemaeus, Rhinopithecus roxellanae, R. bieti, R. avunculus, Nasalis larvatus, andColobus polykomos in order to gain independent information on the classification and phylogenetic relationships of those species. Phylogenetic
trees were constructed with parsimony analysis by weighting transversions 5 or 10 fold greater than transitions. Our results
support the following conclusions: (1) the Old World monkeys are divided into two subfamilies; (2) that among the colobines,Colobus, the African group, diverged first, andNasalis andRhinopithecus form a sister clade toPygathrix; (3) that there are two clades within leaf monkeys, i.e. 1)S. entellus, T. johnii, andT. vetulus, and 2)T. phayrei andT. francoisi; (4) thatRhinopithecus avunculus, R. roxellanae, andR. bieti are closely related to each other, and they should be placed into the same subgenus; (5) thatRhinopithecus is a distinct genus; and (6) that the ancestors of Asian colobines migrated from Africa to Asia during the late Pliocene
or early Pleistocene. 相似文献

根据最优分配理论( optimal partitioning theory,OPT),在自然环境中,由于地上和地下资源在空间上的分离,陆生植物需要调整其地上和地下部分的生物量分配以平衡对资源的吸收。研究结果[1-2]显示:在植物地上资源严重受限时,叶片的生物量分配相对增加;而地下资源严重受限时,根的生物量分配相对增加。然而,植物的生物量分配对资源的响应较为复杂。首先,除了生物量分配,形态变化也是植物调节资源吸收的重要手段,例如,植物通过增加比叶面积提高对光照的吸收,通过调整比根长响应土壤养分的变化[3-4];并且,一些植物甚至以形态响应为主,生物量分配的变化并不明显[3,5]。此外,某些植物还有一些特殊的资源平衡方式,例如,克隆植物通过构件之间的养分传输平衡资源在空间上的分配不均[6];拥有特化储藏器官的植物可依靠大量储藏物质来平衡资源在时间上的分配不均[7]。植物所具有的丰富的资源响应方式决定了其多样的资源策略。 相似文献

Understanding female reproductive characteristics is important for assessing fertility, interpreting female behavior, and designing appropriate conservation and captive management plans. In primate species lacking morphological signs of receptivity, such as most colobines, determination of reproductive parameters depends on the analysis of reproductive hormones. Here, we use fecal hormone analysis to characterize cycle patterns (N=6 females) and gestation length (N=7 females) in a group of wild Phayre's leaf monkeys (Trachypithecus phayrei crepusculus) in Phu Khieo Wildlife Sanctuary, Thailand. We found that both fecal estrogen (fE) and progestin (fP) levels showed clear biological patterns indicative of ovulation and conception. However, because fP patterns were inadequate in determining the end of the luteal phase, we used fE rather than fP patterns to delineate menstrual cycle parameters. We found a mean cycle length of 28.4 days (N=10), with follicular and luteal phases of 15.4 (N=10) and 12.5 days (N=14), respectively. On average, females underwent 3.57 (N=7) cycles until conception. Average gestation length was 205.3 days (N=7), with fE levels increasing over the course of pregnancy. Overall, the reproductive characteristics found for Phayre's leaf monkeys were consistent with results for other colobine species, suggesting that fecal hormone monitoring, particularly for fE metabolites, can provide useful reproductive information for this species.

Primate population assessments provide the basis for comparative studies and are necessary prerequisites in determining conservation
status. The most widely used assessment method is line transect sampling, which generates systematic data quickly and comparatively
inexpensively. In contrast, the presumably most reliable method is long-term monitoring of known groups, which is both slow
and costly. To assess the reliability of various analytical methods, we compared group and population densities for white-handed
gibbons (Hylobates lar carpenteri) and Phayre’s leaf monkeys (Trachypithecus phayrei crepusculus) derived from transect walks with those from long-term group follows at Phu Khieo Wildlife Sanctuary, Thailand. Our assistants
and we regularly walked a 4-km transect over 30 mo (480 km total), resulting in 155 gibbon sightings and 125 leaf monkey sightings.
We then estimated densities via 1) DISTANCE and 2) the Kelker method based on perpendicular distances (PD) or animal-to-observer
distances (AOD). We compared the 3 estimates to values based on known home ranges (95% kernels), accounting for home range
overlap, combined with group size data. Analyses of line transect data consistently overestimated group densities for both
species, while underestimating group size for leaf monkeys. Quality of results varied according to the group size and spread
of each species. However, we found, in accordance with previous studies, that values derived via AOD (or its derivations)
matched most closely with population estimates based on home range data. 相似文献

金丝猴躯干骨及四肢骨的研究 总被引:1,自引:1,他引:0
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。 相似文献
