About this Research Topic
Wetland ecosystems are hotspots of biogeochemical cycling and the hydrological and biogeochemical functioning of wetland soils are intricately linked to physical, chemical and microbial processes. These processes are dynamic and are routinely disrupted by changing hydrological and climatic conditions such as during wetting and drying, freezing and thawing, and changing water flow regimes. Spatial and temporal variations in chemical properties, temperature, and water-saturation in wetland landscapes may enhance the turnover of carbon, nutrients and redox-active metals, in most of cases resulting in pulses of greenhouse gases (CO2, CH4 and N2O), products of aerobic and anaerobic microbial respiration. Unraveling the mechanisms behind measurable biogeochemical responses to environmental drivers, requires integrative approaches that allow high temporal and spatial “access” to biogeochemical information.
This Research Topic will focus on cross-disciplinary research that advances our mechanistic understanding of the function of biogeochemical processes and microbial interactions in wetland ecosystems. This Research Topic aims to bring together wetland hydrologists, biologists, ecologists, soil scientists, biochemists, and geochemists to share cutting-edge research on all wetlands (i.e., peatlands, marshes, swamps, etc.).
In particular, we encourage the submission of new, developing, novel methodologies, and coupled experimental and modelling approaches that address the role of dynamic hydrological conditions on modulating wetland (bio)geochemical processes of nutrients and contaminants, carbon fluxes and microbial community distributions in wetland environments.
