生物地理学

MacArthur and Wilson's theory of island biogeography states that the number of species found on an island is determined by a dynamic equilibrium between the immigration of new colonizing species and the extinction of previously established ones.

麦克阿瑟和威尔逊的岛屿生物地理学理论指出，岛屿上物种的数目是由新移殖来的物种和以前存在物种的灭绝之间的动态平衡决定的。

The development of earthworm ecology was constrained by the complex feature of soil, the scarce knowledge of natural history and biogeography of earthworms, and the low efficiency of approaches in field manipulation of earthworm community.

土壤本身的复杂性，蚯蚓自然历史和生物地理学知识的缺乏，野外控制蚯蚓群落方法的滞后等都限制了蚯蚓生态学的发展。

Speculating on the origin of Gaultheria, two different hypotheses were suggested, one of Gondwanan origin, and the other of Laurasian origin.

本文概述了近年来白珠树属的分子系统学和生物地理学研究进展，并对该属尚存的一些问题进行了讨论。

Speculating on the origin of Gaultheria, two different hypotheses were suggested, one of Gondwanan origin, and the other of Laurasian origin In the present paper, recent advances in molecular phylogenetics and biogeography of Gaultheria are summarized and some problematical issues within the genus discussed.

关於白珠树属的起源问题存在两种不同的推测：一种观点认为该属起源於南半球的冈瓦纳古陆；另一种观点则认为其起源於北半球的劳亚古大陆。本文概述了近年来白珠树属的分子系统学和生物地理学研究进展，并对该属尚存的一些问题进行了讨论。

SeamountsOnline is a NSF-funded project designed to gather information on species found in seamount habitats, and to provide a freely-available online resource for searching, downloading, mapping, and analyzing patterns of biogeography in these data.

"海山生物学信息数据库"是美国国家科学基金会资助建立的，收集了海山生境中的大量物种信息，并且可以在线检索和下载，利用这些数据可以进行生物地理学分析或制图。

Resolving the higher-level relationships among ostariophysan and related fishes will aid in resolving basal teleostean divergence and provide basis to historical biogeographic analysis of major freshwater fish groups.

解决骨鳔鱼类及其相关类群的高阶系统发育关系有助于解决基部真骨鱼的分化，而且为主要的淡水类群——世界性分布的耳鳔系鱼类的历史生物地理学分析奠定基础。

The site also provides biogeographic evidence of the evolution of the island.

这个保护区也提供了这个岛进化的生物地理学证据。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
