About this Research Topic
The characterization of how the abundance and distribution of marine microorganisms, the structure of microbial communities and their provided ecosystem functions respond to the diverse environmental gradients is of fundamental importance to our understanding of the biogeochemistry of the oceans. The contributions of ecological gradients to microbial community stability and function are of particular importance for the estuarine, coastal and marginal sea environments, which have been experiencing a multitude of anthropogenic perturbations. The responses of the affected microbial communities to the human-mediated environmental impacts are difficult to predict and future modeling will require the collection of large empirical data sets. Greater understanding of microbial responses to natural and anthropogenic environmental gradients may also help us to understand the responses of marine ecosystems to global climate change and other large-scale environmental perturbations such as ocean acidification and spatial ocean deoxygenation.
This Research Topic focuses on studies (including original research, methods, perspectives, minireviews and reviews) that investigate and discuss the response of marine microorganisms, communities and their ecological functions to natural and anthropogenic environmental gradients. Contributions that describe ecological characteristics or the development of methods suitable for the study of marine microbial communities that participate in the biogeochemical cycling of C, N and S, in micro-, small-, or geographic-scale gradients are particularly encouraged.
Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
