In the first chapter, using fragments of COI gene, we studied the phylogenetic relationships among species of five familes of Acridoidea with MP and Bayesian methods. The results were as follows:(1) Species of Acrididae, Gomphoceridae and all the Arcypterinae species of Arcypteridae are monophyletic. Species of Oedipodidae are supported as a monophyleticgroup, Ceracrinae species of Arcypteridae cluter together to make a monophyletic group. Epistaurus aberrans and Xenocatantops humilis is a phylogenetic group, Stenocatantops splendens and Hieroglyphus banian is also a phylogenetic group.
我们首先利用COI基因序列片段，使用最大简约法、贝叶斯法研究了斑腿蝗科、剑角蝗科、斑翅蝗科、网翅蝗科和槌角蝗科5个科42种的系统发育关系，得到如下结果：（1）由所有网翅蝗亚科的物种与剑角蝗科绿洲蝗亚科和槌角蝗科的物种组成一个单系群；斑翅蝗科的物种组成一个单系群；网翅蝗科的竹蝗亚科的黄脊雷蓖蝗和青脊竹蝗聚在一起形成单系群；斑腿蝗科的长翅十字蝗和大斑外斑腿蝗亲缘关系较近，形成一个单系群；长角直斑腿蝗和等歧蔗蝗始终聚在一起，形成一个单系群。

Since the species quantity at the shrub, herb and liane in D is more than that in C, The Shannon-Wiener index and the species' evenness showed that human-caused disturbance affected much more to the species at upper communities and the tall trees were not recovered entirely in D.
群落各层次的Shannon-Wiener指数及其均匀度计算表明，人为干扰对群落上层物种多样性影响较大，D群落高大乔木待恢复。D群落经过多年封山育林，由于种类入侵和竞争，正在形成物种更为丰富的当地典型地带性植被类型。

Speciation The formation of one or more new SPECIES from an existing species.
物种形成：从一现存物种中新形成另一或多种新的物种，这一过程称为物种形成。
-
There are four geographic modes of speciation in nature, based on the extent to which speciating populations are geographically isolated from one another: allopatric, peripatric, parapatric, and sympatric.
自然界有四种物种形成的地理学模式，基于形成物种的各群体之间地理隔离的程度分为：异域的、边域性的、领域性的和同域的物种形成。
-
Allopatric speciation occurs when the new species evolves in geographic isolation from the parent species.
异域性物种形成与原来种由于地理隔离而进化形成新种，为异域性物种形成。
-
But even if life on earth turned out to have a nonevolutionary origin(for instance, if aliens introduced the first cells billions of yearsago), evolution since then would be robustly confirmed by countlessmicroevolutionary and macroevolutionary studies.
新物种来自旧物种，如果它们获得了足够多的，能够持续遗传的差异，又达到了足够从原有族群中区别开来的数量，新的物种就形成了。原有物种可能继续存在，也可能会灭绝。

In the 1920s Rensch, who like Mayr did field work in Indonesia, analyzed the geographic distribution of polytypic species and complexes of closely related species paying particular attention to how variations between different populations correlated with local environmental factors such as differences in climate. In 1947 Rensch would write a book, eventually translated into English under the title Evolution above the species level, that looked at how the same evolutionary mechanisms involved in speciation might be extended to explain the origins of the differences between the higher level taxa.
在二十世纪二十年代，像迈尔一样从事野外研究的任许在印度尼西亚分析了多型物种的地理分布以及近缘物种复合体系，特别注意了不同群体之间的变异是如何与当地的环境因素相关的。1947年，任许决定写一本书，这本书最终被译成英文，书名为《物种以上水平的进化》；该书研究了参与物种形成的同样的各种进化机制，如何被延伸用于解释更高层次分类单元的差异的起源。
-
People have argued that the evidences of sympatric speciation are in fact examples of micro-allopatric, or heteropatric speciation.
有人曾声称，同域物种形成的证据，事实上是微型异域性物种形成或不同域物种形成的例子。
-
Sympatric speciation refers to the formation of two or more descendant species from a single ancestral species all occupying the same geographic location.
同域物种形成指的是由一个祖先物种形成两个或两个以上的后裔物种，所有物种都居住在同一地理位置。
-
The book covers both plants and animals, and deals with all relevant areas of research, including biogeography, field work, systematics, theory, and genetic and molecular studies, with special emphasis to topics,including sympatric speciation, reinforcement, the role of hybridization in speciation, the search for genes causing reproductive isolation, and mounting evidence for the role of natural and sexual selection in the origin of species.
该书内容覆盖植物和动物，并且涉及所有相关的研究领域，包括生物地理学，野外工作，系统分类学，理论，和遗传和分子研究，特别强调了包括同区域物种形成，增强，杂交在物种形成中的作用，寻找导致生殖隔离的基因，寻找自然和性别选择在物种起源中作用的证据。

bottleneck：狭口
这些在通过创始者种群的狭口(bottleneck)时比在一个稠密而又大的物种中通过缓慢的选择过程更容易实现. 某一新物种是通过地理物种形成和染色体物种形成而产生的说法并没有矛盾. "边缘隔离"这一提法用于种群密度小和扩散能力大大降低的物种时就多少有些含糊不清.
-
speciation：物种形成
可是因为他对圣经的忽略(出于对造物主的反叛而不接受圣经),他不明白"物种形成"(speciation)不过是上帝设计的一个办法,以便那些以超自然的力量创造的初始物种能够产生美妙的变种,并且能够适应挪亚时代长达一年的全球性洪水之后被诅咒的地球环境.
-
speciation：种的形成
朱海军对物种形成的当代研究一无所知,我给他列了文献他也看都不看(也许看不懂),然而却又想当然地认为这些研究都证明了拉马克主义:"在特殊条件下,生物变异加速,种的形成(speciation)加快,这正是支持拉马克主义的.

speciation：种形成
如果说"物种形成"(speciation)是合理的,那么"物亚种形成"(subspeciation)似乎同样成立. 因此,...
-
Allopatric speciation：异域物种形成
同域物种形成,系在单一族群中引发的物种形成,这是广为人知但仍然有争议的物种形成理论;而异域物种形成(allopatric speciation)则比较为学术界接受. 我们认为快速周期变化的环境可能是同域物种形成的先决条件. 快速周期变化的环境先让一物种形成不同的型态,

sympatric speciation：同域物种形成
而到了2005年,英国王家植物园(邱园,Kew Garden)的植物学家文森特.萨沃莱南(Vincent Savolainen)率领的研究团队,又要从岛屿入手,验证进化论中的一个著名假说-同域物种形成(sympatric speciation)了.
