查询词典 trophic nuclei

There was enrichment of the heavier isotope of mesoplankton with increasing grain size, showing carbon isotope enrichment along trophic levels.

中型浮游动物随粒径的增大，其δ13C值增大，显示出营养层次的碳同位素富集作用，但不同粒级组分相互间δ13C值也存在着相当程度的重叠，实际上这也是其生物组分有重叠的反映。

Recently, NGF was suggested to exert an acute effect on nociceptive sensory neurons in addition to its trophic effect.

最近的研究表明NGF除了具有神经营养作用以外，还可在感觉神经元感受伤害性刺激的过程中发挥作用。

Eugene Odum, one of the founders of the science of ecology, stated:"Any unit that includes all of the organisms (ie: the "community") in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (ie: exchange of materials between living and nonliving parts) within the system is an ecosystem."

一位生态科学的奠基人，说过：&任何单位，它包括某一地区内所有的生物体，这些生物体同自然环境相互作用引起能量的流动，从而生成营养结构、生物多样性和物质循环（如：有生命体和无生命体之间的物质转化），这样的单位就是生态系统。&

According to the modified Carlson's trophic state index, the lake has recently been varied between oligotrophic and mesotrophic.

依据修正的卡尔森营养状态指数公式，计算得到整个千岛湖属贫—中营养型。

The difference in δ 13 C values (2 88‰±0 31‰) between upland buzzards and small mammals was much larger than the differences reported previously, 1‰-2‰, and showed significant difference, while 1 31‰± 0 34‰ between upland buzzard and passerine bird species did not differ from the previously reported trophic fractionation difference of 1‰-2‰.

基于碳同位素的分馏模式(即动物和它食物之间稳定性碳同位素分馏在 1‰～ 2‰之间)，我们推断经大规模灭鼠后，大的食性发生了较大变化，其食物主要来源于高寒草甸的雀形目鸟类，而非原来的小型哺乳类。

Phenological responses to climate change differ across trophic levels1, 2, 3, which may lead to birds failing to breed at the time of maximal food abundance.

气候变化可能产生的生态效应经常出现在新闻报道中，这种潜在影响是否能够被预测的问题也是这样。

The plant-parasitic nematodes were the dominant trophic group,and Rhabditis,Helicotylenchus and Rotylenchus were the dominant faunas.

土壤线虫数量繁多，种类丰富，分布广泛，形态和习性多样，是土壤中重要的生物类群。

In addition,exotic C4 plant Spartina alterniflora is rapidly invading the salt marshes in the Yangtze River estuary,and displacing the native C3 vascular plants Phragmites australis and Scirpus mariqueter.It is no clear whether the C4 vascular plant invasion has serious impact on food web structure and trophic function of the salt marshes of the Yangtze River estuary.

另外，外来种互花米草正在快速入侵长江口盐沼湿地，这种C_4维管植物入侵将对盐沼湿地食物网及其营养功能会产生什么样的影响也是一个值得探讨的问题。

The shaping method of noncircular part and the tool holder's radial motion characters in noncircular turning process are discussed in detail in the thesis.

论文详细研究了非圆零件的成型方法和加工过程中刀架的径向运动规律。

I have not really liked him,I do not like his this kind of disposition.

我没有真的喜欢他，我不喜欢他的这种性格。
