氮污染影响许多泥炭地，影响其生物多样性和生态系统功能。微生物控制着养分循环，构成了泥炭地生物多样性的大部分，但它们对氮的反应特征不明显，可能取决于沉积的形式。使用一个独特的现场实验，我们表明，氨暴露在现实的点源水平与一般的转变从异养（细菌和真菌）到自养（藻类）的优势和总生物量的增加。较大的有壳变形虫的生物量增加，这表明微生物捕食者的食物供应增加。结果表明，氮污染的广泛影响，并建议在这些生态系统中的微生物群落为基础的生物指示剂的潜力。
Nitrogen pollution affects many peatlands with consequences for their biodiversity and ecosystem function. Microorganisms control nutrient cycling and constitute most of the biodiversity of peatlands but their response to nitrogen is poorly characterised and likely to depend on the form of deposition. Using a unique field experiment we show that ammonia exposure at realistic point source levels is associated with a general shift from heterotrophic (bacteria and fungi) to autotrophic (algal) dominance and an increase in total biomass. The biomass of larger testate amoebae increased, suggesting increased food supply for microbial predators. Results show the widespread impacts of N pollution and suggest the potential for microbial community-based bioindicators in these ecosystems.
