Este trabalho discute os efeitos das mudanças do uso do solo na biogequímica dos rios da bacia de drenagem do rio Ji-Paraná (Rondônia). Nesta região, a distribuição espacial do desmatamento e das propriedades do s...

Climate change and variability are major societal challenges, and the ocean is an integral part of this complex and variable system. Key to the understanding of the ocean's role in the Earth's climate system is the study...

Large-scale Euro-Atlantic variability, shaped by the polar jet stream, governs weather and climate in the Baltic Sea region, thereby impacting the physical and biogeochemical properties of the Baltic Sea ecosystem. This ...

The expanding deployment of biodegradable mulch films in global agriculture aims to mitigate persistent plastic pollution, yet the fate of resulting biodegradable microplastics (BMPs) in soil ecosystems remains poorly ch...

A área da planície de inundação da Amazônia é estimada em 300 000km² e sua produtividade primária em 1,17 x 10(14) g C yr-1. Deste total de área e produtividade, estimativas sugerem que 43% e 62%, respectivament...

Mineral-associated organic carbon (MAOC) constitutes a major fraction of global soil carbon and is assumed less sensitive to climate than particulate organic carbon (POC) due to protection by minerals. Despite its import...

Soil microbes are the driving force behind soil nutrient cycling, yet the role of their composition and function in controlling forest nutrient cycling is poorly understood and rarely used to predict rates of biogeochemi...

Ecohydrology is a relatively new and rapidly growing subject area in the hydrology curriculum. It is a trans-disciplinary science derived from the larger earth systems science movement and examining mutual interactions o...

Abstract Background Blanket bogs are rare ombrotrophic peatlands that function as important long-term carbon stores. Their persistence depends on strong nutrient limitation, which maintains Sphagnum dominance and suppres...

This chapter provides a global and up-to-date overview of understanding of Hg sources and cycling in the coastal and open oceans, affecting aquatic organisms and human populations. Mercury in the environment exists in th...
