概括

氨排放破坏了循环,影响了脆弱的泥炭地. 测试虫表现出减少的多样性和改变的组合作为高氨沉积的反应,证实了它们作为敏感生物指标的作用.

科学领域:

环境科学环境科学
生态生态学生态生态学
生物监测生物监测

背景情况:

人类活动破坏了全球循环.
主要来自农业的氨 (NH3) 排放量在英国和爱尔兰很高,影响了像泥炭地这样的敏感息地.
由于过度的NH3沉积,泥地恢复受到威胁,危及生态系统服务损失.

研究的目的:

在北爱尔兰的泥炭地里研究丸氨虫作为季节性NH3沉积的生物指标.
为了评估NH3沉积和胞虫组合和多样性之间的关系.
评估试类虫在监测NH3对泥炭地生态系统的影响方面的潜力.

主要方法:

在北爱尔兰的六个泥炭地一年内,季节性地采集了Sphagnum和状虫的样本.
在Sphagnum采样地点附近的地点进行NH3监测.
多变量分析,将NH3沉积水平与丸性虫组合和多样性变化联系起来.

主要成果:

研究人员发现,高NH3沉积量与丸性虫组合的变化之间存在显著联系.
在春季,在NH3沉积量高的地点,虫虫种群的多样性显著减少.
没有观察到藻类食种群的显著扩散,也没有观察到NH3和混合型种群的丰度下降之间的明显联系.

结论:

试剂虫是泥炭地季节性NH3沉积的有效生物指标.
高的NH3水平会对丸虫虫的多样性和社区结构产生负面影响.
这项研究证实了状虫对于监测敏感泥炭地环境中的NH3污染的有用性.

Overview of Nitrogen Metabolism

Overview of Nitrogen Metabolism

Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of ammonia, ammonium ions, nitrate, nitrite, or nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.
The largest pool of nitrogen available in the terrestrial ecosystem is gaseous nitrogen (N2) from the air, but this...

Comparative Excretory Systems

Comparative Excretory Systems

Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.
