底栖生物

Benthos The organisms that live on the bottom sediments of freshwater and marine ecosystems.

底栖生物：在淡水或海洋生态系统底部生活的生物体。

It's Hazard index showed that if people eat the benthos of harbor area was no risks.

危险指标显示食入港区内的底栖生物并不会产生风险。

Coastal zones are important habitats to fauna, having a primary production for offering such as benthos and sessile organisms.

摘要沿岸海域一直是生物重要的栖地，并且提供像底栖生物或附著生物相当高的基础生产。

And Octopus ocellatus belongs to zooplanktons -benthos type.

短蛸属浮游动物和底栖生物食性类型。

Abundant Late Paleozoic brachiopod fossils are contained in the Qiligou section of the Western Mountains, Taiyuan, Shanxi, and 13 benthic communities have been recognized.

太原西山七里沟晚古生代剖面含有丰富的腕足动物化石，共可识别出13个底栖生物群落。

Consequently, sulphidic bottom waters on continental shelves may be more common than previously believed, and could therefore have an important but as yet neglected effect on benthic communities.

关于硫化物会被亚表层海水中的细菌完全耗尽、从而会被浅层沿海水域的遥感或监测活动忽略的发现表明，大陆架上含硫化物的海底水域也许要比我们所想的更普遍，所以有可能对底栖生物群落产生一个重要的、但以前却被忽略的影响。

The results show that the benthons were not polluted by the heavy metals, but the concentrations of Pb and Cd in crustacea and mollusk were potentially serious. The contents of Cd in crustacea was beyond the Standard Indexes of the seafood. The contents of Cd in mollusk was same as Stan...

结果表明，底栖生物中Hg、Pb、Cd、As含量较低，但甲壳动物和软体动物体内Pb和Cd具有潜在的严重积累问题；甲壳类Cd含量已严重超人体消费标准，软体类的Cd含量等于人体消费标准值，甲壳动物和软体动物的可食性应引起人们的关注。

The average abundance of nematodes was 1801.82 ind.10cm-2, accounting for 95.4% of the abundance of meiofauna, with benthic harpacticoid copepods in the second, accounting for 2.2%.

小型底栖生物数量与环境因子的相关分析表明，影响小型底栖生物数量发生季节变化的主要因子0-2cm表层Chl-a含量。

In the raft mari-culture waters of the Jiaozhou Bay, China, a benthic chamber system for production measurement in situ was established. The O 2-flux was calculated based on the benthic closed-circuit chamber incubations of undisturbed sediment under light and dark conditions for estimating the benthic primary production and respiration.

为对生态系统的健康评估及底栖生物资源的开发利用提供技术支撑，在胶州湾筏式养殖水域，建立了底栖生物生产力现场测试系统，并在光照和黑暗条件下测定了沉积物海水界面溶解氧随时间的变化、计算了氧通量、估算了底栖总初级生产力和群落呼吸。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
