摘要

盐沼位于世界各地海洋的陆地-水生界面。盐沼与高地或近海盐沼的独特之处在于,维管植物和饱和盐碱地的初级生产力很高,这导致了急剧的氧化还原梯度以及电子受体和供体的多样性。此外,根系缺氧和潮汐强迫的动态性质导致了促进氮循环的独特生物地球化学条件。在这里,我们强调了我们对盐沼中关键氮循环过程的理解的最新进展,并讨论了需要进一步研究的领域,以更好地预测盐沼氮循环将如何应对未来的环境变化。

Salt marsh nitrogen cycling: where land meets sea.

Salt marshes sit at the terrestrial-aquatic interface of oceans around the world. Unique features of salt marshes that differentiate them from their upland or offshore counterparts include high rates of primary production from vascular plants and saturated saline soils that lead to sharp redox gradients and a diversity of electron acceptors and donors. Moreover, the dynamic nature of root oxygen loss and tidal forcing leads to unique biogeochemical conditions that promote nitrogen cycling. Here, we highlight recent advances in our understanding of key nitrogen cycling processes in salt marshes and discuss areas where additional research is needed to better predict how salt marsh N cycling will respond to future environmental change.

期刊介绍: Trends in Microbiology serves as a comprehensive, multidisciplinary forum for discussing various aspects of microbiology, spanning cell biology, immunology, genetics, evolution, virology, bacteriology, protozoology, and mycology. In the rapidly evolving field of microbiology, technological advancements, especially in genome sequencing, impact prokaryote biology from pathogens to extremophiles, influencing developments in drugs, vaccines, and industrial enzyme research.
