Estuaries are important features for global biogeochemical understanding, due to their
highly coupled interaction between sediment and water. In those places, the land-sea …

Some fish species can be used as target species and bioindicators of environmental
disturbances. In this context, biological indicators such as the length, weight, and height of …

Over the last decades, regional climate changes, erosion, and heightened agricultural
runoffs have increased nutrient and particle input in rivers, unbalancing the biogeochemical …
