生物群落

Photosynthesizing communities living in coastal recharge areas preferentially fix 12C, such that the biomass is typically over 20% depleted in 13C relative to the marine inorganic C reservoir.

海岸补偿地区的营光合作用的生物群落更多的固定了12C，所以富含这种生物量的地区通常记录了相对海洋无机碳超过20%的缺乏13C。

Species and biological communities have difficulty adapting to change.

物种和生物群落难以适应变化。

According to the characters of the micro- ecological systeml both complicated and stable, which is formed from the relationship of symbiosis and reproduction among EM biological groups, we choose the organic waste water and animals as the study abjects. They provide the best experimental terms.

根据EM生物群落相互间的共生增殖关系而形成的一种复杂而稳定的微生态系统特点，选择有机废水和畜禽场作为研究对象，优选出最佳实验条件。

We don't know enough yet how to invent biomes without installing pumps.

尽管我们还不知道怎么在不安装泵的情况下构建生物群落。

如何影响气候的性质和地点的生物群落？

Figure 3-6 shows how major biomes in the United States are related to its different climates.

图3-6显示，在美国的生物群落和气候差异是有关联的。

The biosphere is a global ecosystem that can be broken down into regional or local ecosystems, or biomes.

生物圈是一个全球性生态系统，可以分成地区性的或局部性的生态系统，或称生物群落。

In the community of pack ice with high biomass, the grazing rates of micro-fauna to algae ranged from 0.09 to 0.21 day-1, which corresponded to remove 8 to 23% of algal preliminary biomass or 58 to 123% of primary production, suggesting that the herbivory was one of the most important passways of carbon flow within the micro-community.

浮冰生物群落中，小型动物区系对藻类的摄食速率为0.09 和0.21 day-1之间，相当于每天摄食8-23 %的藻类初始生物量和58-123 %的产量。
