Moluscos marinos bentónicos del Cuaternario de Bahía Anegada (sur de Buenos Aires, Argentina): variaciones faunísticas en el Pleistoceno tardío y Holoceno [PDF]
, 2013 A lo largo del área costera del Atlántico sudoccidental se observan depósitos marinos que representan los dos últimos eventos transgresivos del Cuaternario (Pleistoceno tardío y Holoceno).

Flaws in the methodologies for organic carbon analysis in seagrass blue carbon soils
Limnology and Oceanography: Methods, Volume 21, Issue 12, Page 814-827, December 2023., 2023 Abstract The ability to accurately measure organic carbon (OC) in marine sediments or soils is overall taken for granted in scientific communities, yet this seemingly mundane task remains a methodological challenge when the soil matrix contains calcium carbonate (CaCO3), creating inaccuracies in Blue Carbon estimates.

Revista Brasileira de Geomorfologia, 2021 As variações do nível relativo do mar (VNRM) tiveram um papel importante na formação das planícies costeiras fluminenses durante o Holoceno, sendo responsáveis pela construção de extensas feições deposicionais costeiras na Região dos Lagos.

Past human‐induced ecological legacies as a driver of modern Amazonian resilience
People and Nature, Volume 5, Issue 5, Page 1415-1429, October 2023., 2023 Abstract People have modified landscapes throughout the Holocene (the last c. 11,700 years) by modifying soils, burning forests, cultivating and domesticating plants, and directly and indirectly enriched and depleted plant abundances. These activities also took place in Amazonia, which is the largest contiguous piece of rainforest in the world, and for

New Phytologist, Volume 239, Issue 6, Page 2126-2137, September 2023., 2023 Summary The response of Posidonia oceanica meadows to global warming of the Eastern Mediterranean Sea, where the increase in sea surface temperature (SST) is particularly severe, is poorly investigated. Here, we reconstructed the long‐term P. oceanica production in 60 meadows along the Greek Seas over two decades (1997–2018), using lepidochronology. We

Seagrass Posidonia escarpments support high diversity and biomass of rocky reef fishes
Ecosphere, Volume 14, Issue 6, June 2023., 2023 Abstract Although seagrass meadows form a relatively homogenous habitat, escarpments, which form three‐dimensional structures and originate from the erosion of seagrass peat, can provide important habitat for reef fishes. Here, we compare fish assemblages and habitat structural complexity among seagrass Posidonia australis escarpments and canopies, as ...

Methane Emissions in Seagrass Meadows as a Small Offset to Carbon Sequestration
Journal of Geophysical Research: Biogeosciences, Volume 128, Issue 6, June 2023., 2023 Abstract Seagrass meadows are effective carbon sinks due to high primary production and sequestration in sediments. However, methane (CH4) emissions can partially counteract their carbon sink capacity. Here, we measured diffusive sediment‐water and sea‐air CO2 and CH4 fluxes in a coastal embayment dominated by Posidonia oceanica in the Mediterranean ...

Species Traits and Geomorphic Setting as Drivers of Global Soil Carbon Stocks in Seagrass Meadows
Global Biogeochemical Cycles, Volume 36, Issue 10, October 2022., 2022 Abstract Our knowledge of the factors that can influence the stock of organic carbon (OC) that is stored in the soil of seagrass meadows is evolving, and several causal effects have been used to explain the variation of stocks observed at local to national scales. To gain a global‐scale appreciation of the drivers that cause variation in soil OC stocks,
