The efforts to open the gate to a powerful nation in 2012 that marks the centennial birth anniversary of Kim Il Sung are a worthwhile struggle to inherit the glorious history and traditions of our Party and revolution that started on Mt.

Effect on birds community:Through the analysis of the correlation between the birds amount and frequency in the 9 parks and the 12 structure indexes of the parks,we reach the conclusion that Passer rutilans and Turdus merula are mostly effected by the area of the habitat, while Carduelis spinus,Parus venustulus,Aegithalos concinnus,Anthus hodgson,Paradoxornis webbianus and Trachybaptus ruficollis are mostly effected by humanlnterference.
对鸟类的影响:通过对市区9个公园的生境破碎化相关的结构、连通性、隔离度、人为干扰等12个特征变量与鸟类数量和出现频率的相关分析,发现常见鸟类中,麻雀和乌鸫对生境面积存在显着的相关关系;而黄雀、黄腹山雀、红头长尾山雀、树鹨、棕头雅雀以及小鸊鷉受到人为干扰的影响较为明显;白头鹎和珠颈斑鸠的数量与生境斑块的形状指数呈负相关;麻雀的数量随着斑块中灌木层密度的增加而上升;白鹡鸰随着乔覆盖度的增加而减少。

Our interpretation of the results from parsimony, distance and maximum likelihood based phylogenetic analyses suggest:(1) African colobines and Asian colobines have been independent evolutionary entities for a long time; the divergent time is estimated to occur 10 million years ago based on a molecular clock of 2% substitution per site per million years;(2) both Rhinopithecus and Trachypithecus could be regarded as separate genus;(3) Pygathrix and Rhinopithecus are sister groups while Presbytis and Trachypithecus are closely related;(4) both the Sichuan and Yunnan snub-nosed monkey represent valid species respectively;(5) within genus Trachypithecus, T. phayrei is closely related to T. cristatus and T. auratus, while T. francoisi is distinct from them; the white-headed leaf monkey, however, should be a subspecies of T. francoisi;(6) within genus Presbytis, P. thomasi should be separated as a valid species from P. melalophos, but the genetically divergent degree between P. comata and P. melalophos implies that P. comata may just be a subspecies of P. melalophos.
结果表明:(1)非洲疣猴与亚洲疣猴的分歧已非常明显,按分子钟推算的分歧时间约在1,000万年前;(2)Rhinopithecus和Trachypithecus均应成为独立的属;(3)白臀叶猴属与金丝猴属关系较近,Presbytis属和Trachypithecus属关系也较近;(4)我国的川、滇金丝猴应分别被视为独立的物种;(5)在Trachypithecus属中,菲氏叶猴与银叶猴(T.cristatus)和乌木叶猴亲缘关系较近,黑叶猴(T.francoisi)则与它们的关系较远,曾被怀疑为一个种的白头叶猴(T.f.leucocephalus)应只是黑叶猴的一个亚种;(6)在Presbytis属内,托氏叶猴应从僧帽叶猴(P.melalophos)中独立出来成为一个有效种,但我们的结果倾向于将灰发叶猴置为僧帽叶猴的一个亚种。

Wide expanses of turf grass are sterile habitats attracting less desireable "generalist" species, such as feral pigeons, starlings, cowbirds, and grackles, all of which compete with our native songbirds for food and nesting spots.
大面积的草皮是贫瘠而缺乏生产力的。只能吸引一些&俗鸟&,比如鸽子,八哥,白头鹎啥的。这些优势种的鸟类占据你的庭院,会阻碍美丽的小鸟到来。(呵呵这个作者搞鸟类歧视,我不大赞成,八哥啥的也挺好的——viccent

The Principal componants analysis shows that the main gene of the red crane to habitat selection is the food, veil water and vegetation, for the white crane, food and veil are the main gene, for the white nape crane, the main gene are food ,water and vegetation, for white head crane are veil water and vegetation, however, food, veil and vegetation are the main gene for the common cranes habitat selection.
对五种鹤的主成分分析表明丹顶鹤对生境选择的主因子为食物因子、隐蔽因子、水因子和植被因子;白鹤对生境选择的主因子为食物因子和隐蔽因子;白枕鹤对生境选择的主因子为食物因子、水因子和植被因子;白头鹤对生境选择的主因子为隐蔽因子、水因子和植被因子;灰鹤对生境选择的主因子为取食适宜性因子、隐蔽因子和植被因子。
