Wetland ecosystems are transitional habitats between terrestrial and aquatic systems that are characterized by periodic or permanent inundation, hydric soils, and vegetation adapted to water-saturated conditions. They encompass diverse types such as marshes, swamps, bogs, and fens, each defined by hydrological regime, nutrient status, and dominant plant functional groups. Wetlands exhibit high biogeochemical activity, particularly in carbon, nitrogen, and phosphorus cycling, driven by redox gradients and microbial processes under anoxic or fluctuating oxygen conditions. They support high biodiversity, act as sinks or sources of greenhouse gases (e.g., CO₂, CH₄, N₂O), regulate hydrology via water storage and attenuation, and are focal systems in research on ecosystem services, climate feedbacks, and landscape connectivity.
The tidal environment of mangrove forests serves as nurseries for many fish species. Researchers at the University of Gothenburg have measured carbon dioxide and oxygen levels in 23 of the world's mangrove areas. The study, ...

For years, the Prairie Pothole Region has bothered me in a very specific way. On a map, it looks like a normal landscape: fields, gentle slopes, small streams. But hydrologically, it behaves like something else entirely. ...
Floodplains face increasing pressure: currently protected areas will not be sufficient to preserve the species living in them in the future, a review study conducted under the direction of the Swiss Federal Institute for ...
