Salinization in estuarine wetlands significantly alters the balance between their nitrogen (N)
removal and retention abilities but these processes have not yet been characterized …

To cope with increasing nitrogen loading to estuarine systems, the demand for removal via
denitrification is rising. Understanding how the connections between biogeochemistry and …

Coastal sediments are major contributors to global carbon (C) mineralization and nutrient
cycling and are tightly linked to processes in the pelagic environment. In this study, we …

Coastal ecosystems are sensitive to the input of chemicals originating from submarine
groundwater discharge (SGD). The mixing zone between freshwater and saltwater in beach …

This study investigated the polycyclic aromatic hydrocarbons (PAHs) occurrence, and their
impact on the microbial community and PAH-degrading genera and genes in the Knysna …

The impoundment of rivers by dams has significantly modified sedimentation patterns and
trophic structures. As a result, the algal-derived organic matter (OM), as opposed to …

Human activities alter biodiversity, influencing bottom-up and top-down control on food webs
which can affect ecosystem functioning. In marine ecosystems, large bivalves play a critical …

Salt marshes are key ecosystems for biogeochemical cycling of nutrients in coastal areas,
providing essential sequestration of contaminants and elemental organic forms while …

Supply of bio-labile dissolved organic matter (DOM) has been assumed to be a key factor for
the intensity of nitrate (NO3–) removal in permeable coastal sediments. In the present study …

The conversion of organic matter by extracellular enzymes can reveal important insights into
carbon and nutrient cycling. The activity and stoichiometry of hydrolytic extracellular …
