Unless smokers are consistently located near more hospitable warm-water vents, chemosynthesis can account for only a fraction of the vent faunas.

除非烟囱始终位于更适宜的暖水喷口附近，否则化学合成只能占喷口动物群的一小部分。

Most deep-sea faunas rely for food on particulate matter, ultimately derived from photosynthesis, falling vent would dwarf any contribution from advection.

大多数深海动物依靠颗粒物质作为食物，这些颗粒物质最终来自于光和作用，下降的排放口会使平流的作用相形见绌。

We shall appreciate this difficulty more clearly, by looking to certain existing faunas and floras.

通过观察某些现存的动物群和植物群，我们就能更清楚地了解这种困难了。

In this paper, a detailed comparison is made between the four phases in the Tarim Basin and the corresponding faunas in South China and North China.

The Gaotege fauna reflects a predominantly temperate steppe habitat, with local shrub and freshwater bodies, similar to the Ertemte and Bilike faunas.

动物群的组合指示了一个以温带草原为主，局部地方有灌木丛林和水体的生态环境，与二登图和比例克动物群的情况相似。

There are also resemblances among Early Silurian rugose coral faunas of the Yangtze region, eastern Australia, and eastern North America to some extent.

扬子区早志留世珊瑚群与澳大利亚东部、北美东部同期珊瑚也有一定的相似性。

These tracks fill a gap in the record of Neogene mammals in this important part of the world and contribute significantly to our knowledge of these faunas.

Change, but not evolution of communities as units, is suggested in detailed descriptions of the changes in faunas in the Appalachian Basin (Brett and Baird 1995).

在阿巴拉契亚盆地动物区系变化的描述中隐含地表述了变化而不是演化作为一个单位的意思。

Bird banding is one of the important means to research the seasonal migration of birds, and is an effective method in researching the faunas, ecology and morphology of birds.

环志是研究鸟类季节性迁徙的重要手段之一，同时也是研究鸟类区系、生态学、形态分类学等的有效方法。

The fossils show that the bottom of the food chain was dominated by species typical of later Triassic Marine faunas - such as crustaceans, fishes and bivalves - and different from preceding ones.

这些化石揭示了生物链的底层被三叠纪后期海洋生物群典型物种所掌控，这不同于之前的世纪里的动物。
