Article Synopsis
- Tropical estuarine systems are vital for biodiversity and nutrient cycling, but their microbiome diversity is still not fully understood, especially regarding seasonal changes.
- A study conducted in a South Atlantic mangrove-dominated estuary analyzed over 12 million metagenomic sequences and water quality, revealing different microbial families that thrived in wet versus dry seasons.
- The dry season had higher salinity and emphasized nitrogen processes, while the wet season showed increased greenhouse gas production, suggesting a link between microbial diversity and seasonal changes in gas emissions.
The Jacarepaguá Lagoon System (JLS) receives industrial and domestic waste in an urban area with high population density and intense economic activity. The hydrography of the lagoons favours the sedimentation of particulate material transferred from the drainage basin. Water engineering, such as channel dredging and subsea outfall, did not satisfactorily mitigate pollution effects.

Over the last five decades, several approaches have been proposed to discern the trophic state and the natural and cultural processes involved in eutrophication, including the multi-parameter Assessment of Estuarine Trophic Status (ASSETS) index model. This study applies ASSETS to four Brazilian lagoons (Mundaú, Manguaba, Guarapina, and Piratininga) and one estuarine delta (Paraíba do Sul River), set along the eastern Brazilian coast.
