查询词典 trophic level

They provide structural, trophic, and metabolic support to neurons and modulate synaptic activity.

星形胶质细胞为神经元提供结构，营养和代谢上的支持并调节突触活动。

Models of communities with different levels of trophic connectance show that complexity reduces resilience and stability.

具有不同营养连接水平的许多群落模型，显示复杂性导致恢复力和稳定性下降。

It is the first ecopath model which consists of 13 function groups, and only covers the main trophic flow in the Bohai Sea ecosystem.

它能够给出能量在生态通道上的流动量，便于对生态系统的特征和变化作深入的研究。

Our discussion can be divided into metabolic or trophic relationships and nonmetabolic, particularly mechanical relationhships.

我们的讨论可分为2部。新陈代谢的或是营养的非新陈代谢的或是特定的物质上的关系。

Consequently, changes in diversity at higher trophic levels can significantly alter ecosystem function in natural systems.

这一作用使得生态系统能够缓冲食草动物和植物丰度的较大变化，从而保持食物链的稳定。

Yangcheng Lake, water environmental quality, trophic status index, water environmental capacity.

阳澄湖；水环境质量；营养状态指数；水环境容量

So the study on the trophic elements is helpful to the understanding in the geochemical cycle model and eco-environmental evolution characters.

因而对其湖泊沉积物中营养元素的研究可以为进一步认识云贵高原的外生地球化学循环模式和生态环境演化的特点奠定基础。

Fish is an important component of water ecological system, which seats in the higher trophic postion of aquatic food chain and is thus directly related to human health.

鱼类是水体生态系统中的重要生物组成部分，占据水体食物链中较高的营养阶层，同时也直接联系到人体的安全。

So consequencetly difference in age structure of Engraulis japonicus populations would lead to change its element compositions. Since Engraulis japonicus was one of the most important diet to high trophic fishes such as Scomberomorus niphonius and Trichiurus lepturus, Unbalance of supplying elements of potential diets would directly lead to the facts that some fish species would grow slower and smaller.

因此，鳀鱼种群年龄结构的变化导致了种群元素组成的变化，同时由于鳀鱼是上层鱼类的重要饵料，因此潜在饵料的元素供给失衡，直接导致带鱼等鱼类因鳀鱼资源衰退而生长缓慢，个体瘦小。

Structure index was significantly (P.05) different among three plant species whereas channel index and enrichment index were not. Plant species not only modified abundance of plant-feeding, omnivorous and predatory nematodes, but also percentage of each trophic group. Bacterivorous and fungivorous nematodes were affected most by the differences in plant species.

研究表明在沙地生态系统中，3种植物根际土壤线虫群落的多样性、丰富度、均匀度和线虫总数虽然都存在一定的差异，但不显著；功能多样性指数中结构指数存在显著差异，而通道指数、富集指数不存在显著差异；3种植物对根际土壤线虫群落中各营养类群线虫的比例有显著影响。

If I didn't care what anyone thought, I would.....

如果我不介意别人怎么看，我会。。。。

In recent decades, Chile has mandated earthquake-proofing for new structures, requiring that materials like rubber and features like counterweights be built into the architectural designs to allow buildings to bend and sway during temblors rather than break.

在最近数十年里，智利已经为兴建防震的新土建结构而对建筑材料提出要求，需要的材料类似于橡胶，而特性就象运用在建筑设计中的平衡物体，一旦应用以后，当地震发生时建筑就能弯曲摇摆。
