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.
Eastern Canada has seen a rise in the number of hurricane- and near-hurricane strength events battering its maritime areas, with particularly violent storms in 2003 (Hurricane Juan), 2019 (Dorian) and 2022 (Fiona). While ...
