Aquatic ecosystems, including wetlands, lakes, and paddy soils, play a vital role in the global carbon cycle as carbon sources or sinks. For example, these natural and artificial sites contribute significantly to greenhouse gas emissions (GHGs, such as CO2 and CH4) and primary productivity. The redox potential in these environments undergoes dynamic changes during processes like underground water recharge in unconfined river aquifers, fluctuations in lake sediment water tables, and cycles of flooding and drainage in cultivated lands. These frequent redox fluctuations foster intense interactions between reduced substances, variable metal-bear minerals (for example, Fe-mineral, Mn-mineral), and oxygen (O2), leading to transformations in microbial communities, soil organic carbon, and the generation of reactive oxygen species (ROS). Ultimately, these frequent redox fluctuations significantly alter the microbial-driven carbon turnover cycles within these water-soil environments. Soil microbial species, metabolism, function, and even residues of deceased microorganisms (microbial necromass) distinctly influence the turnover of soil carbon. However, the underlying mechanisms remain poorly understood, and further exploration is warranted.
This Research Topic invites papers addressing one or more aspects of GHGs emissions and carbon fixation from dry-wet cycling regions and aims to deepen our knowledge of the microbial process, potential, and ecological effect on the carbon cycle.
