叶猴类一般有较小的活动面积和相对固定的活动范围，群与群间保持一定的距离避免相互接触.典型的喀斯特环境中黑叶猴群间关系是研究得较少的方面.2013年1-12月，采用瞬时扫描法(Instantaneous Scan Sampling)和全事件取样法(All occurrence Sampling)对扶绥中华村哥利(地名)的5群黑叶猴的群间接触行为进行了研究.
怒江金丝猴(Rhinopithecus stryker)隶属仰鼻猴属(Rhinopithecus).2010年于缅甸首次被发现,2011年10 月在怒江州高黎贡山国家级自然保护区内也证实了该物种的存在.该物种种群数量稀少,被IUCN红色名录列为极度濒危(CR)物种.
Geophagy is common in extant nonhuman primate species,but the exact reasons for it across species remains unclear.Previous diet studies on Yunnan snub-nosed monkey(Rhinopithecus bieti)were only focuse
The activity budgets of primates reflect their survival strategy.Despite existing data on the activity budgets of Yunnan snub-nosed monkeys(Rhinopithecus bieti),little is known about how activity budg
Multilevel societies(MLS),in which polygynous reproductive units are nested in a larger social matrix,represent a highly complex social system documented only in a small number of mammalian species.
猕猴属属于猴科，是灵长类中辐射进化最成功的谱系之一.基于形态学特征和线粒体DNA 序列的分析尚未构建出猕猴属动物清晰、明确的系统进化关系.本研究以地中海猕猴(Macaca sylvanus)、豚尾猴(M.nemnestrina)、藏酋猴(M.thibetana)、熊猴(M.assamensis)、红面猴(M.arctoides)、恒河猴(M.mulatta)、食蟹猴(M.fascicularis)
本文选用牛科动物性染色体上睾丸分化基因及牙釉质蛋白基因的三对特异性引物XY-1/XY-2,SE47/SE48,Y-1/Y-2,首先通过对已知性别的皮张样品进行性别鉴定验证,确定性别鉴定的准确性为100％后,再以可可西里自然保护区卓乃湖地区及新疆阿尔金山自然保护区两大藏羚羊产羔地的藏羚羊胎盘为研究对象,氯仿异戊醇法进行DNA抽提后,利用三对引物鉴定胎盘性别,即藏羚羊新生胎儿性别。
The Common Pheasant,Phasianus colchicus is distributed throughout temperate regions in East and Central Asia,and had been widely introduced into Europe and North America as a game bird.
The watchdog(canis familiaris),the worlds oldest domesticate,is a very close relative of the grey wolf(Canis lupus)and the two species diverged anywhere from 145 00 to 15 000 years ago.
为明确我国六种犬科动物,狼、豺、貉、赤狐、沙狐、藏狐线粒体基因组特点及其与其他犬科动物的系统进化关系,同时为进一步探讨我国各主要分布区狼的系统发育关系和亚种划分问题.
