Mangroves

TROPECOS scientists involved in WP3 reveal that the composition of dissolved organic matter (DOM) in mangrove soils is strongly influenced by mangrove species and their biological traits, including mycorrhizal associations.

This is crucial because DOM plays a key role in carbon cycling and nutrient export from mangroves. These findings highlight that understanding species-specific DOM dynamics is essential to better assess carbon fluxes and the functioning of atoll mangrove ecosystems.

The second TROPECOS field work in mangroves of Rio de Janeiro (Mamangua and Itacoatiara) 24 May 2025 – 7 June 2026, involved 14 TROPECOS research scientists and students from BOREA, LPG, UFF and UFPA. We measured gas fluxes in mangrove soils and waters, dissolved carbon concentrations and water current in tidal creeks, and high resolution dissolved redox species in sediments using 2D gels. 

The second TROPECOS field work in mangroves of Pará (Marapanim and Salinas) 6 May 2025 - 28 May 2025, involved 11 TROPECOS research scientists and students from BOREA, LPG, UFF and UFPA. We measured gas fluxes in mangrove soils and waters, dissolved carbon concentrations and water current in tidal creeks, and high resolution dissolved redox species in sediments using 2D gels. 

This TROPECOS fieldwork in the mangroves of Ouvéa involved a team of six scientists, including a researcher, two PhD students, a post-doc, a researcher technician and an intern from University of New Caledonia.

The week-long mission was made possible through the agreement of the landowners from the Téouta tribe and the hospitality of the women’s association in the Téouta tribe (FAI DOHU association). 

The first TROPECOS field work in mangroves of Rio de Janeiro (Mamangua and Sepetiba), 30 October, 2024 - 9 November, 2024,  involved 15 research scientists and students from BOREA, LPG, iEES, UFF, UFPA and UERJ
