Plastic debris is a growing threat in freshwater ecosystems and transport models predict that many plastics will sink to the benthos. Among the most common plastics found in the Laurentian Great Lakes sediments are polyethylene terephthalate (especially ...

The seasonal dynamics of the NE Black Sea phytoplankton follow the following pattern: small diatoms (spring) ? coccolithophorid Emiliania huxleyi (late spring?early summer) ? large diatoms (summer). Our hypothesis states that nitrogen and phosphorus conc...

Plant canopies divert a portion of precipitation to the base of their stems through ?stemflow?, a phenomenon that influences the canopy water balance, soil microbial ecology, and intrasystem nutrient cycling. However, a comprehensive integration of stemf...

Although mangrove forests occupy only 0.5% of the global coastal area, they account for 10?15% of coastal organic carbon (OC) storage, and 49?98% of OC is stored in sediments. The biogeochemistry of iron minerals and OC in marine sediments is closely rel...

The biogeochemistry of waters is an essential regulator of phytoplankton dynamics, determining the level of species bloom and the change in dominants. This paper investigated the seasonal dynamics of phytoplankton and the nutrient concentrations and thei...

Nitrate is globally the most widespread and widely studied groundwater contaminant. However, few studies have been conducted in sub-Saharan Africa, where the leaching potential is enhanced during the rainy monsoon phase. The few monitoring studies found ...

Polar marine environments host a complex assemblage of cold-adapted auto- and heterotrophic microorganisms that affect water biogeochemistry and ecosystem functions. However, due to logistical difficulties, remote regions like those in close proximity to...

Aquifers provide integral freshwater resources and host ecosystems of largely uncharacterized, truncated endemic microorganisms. In recent history, many aquifers have become increasingly contaminated from various anthropogenic sources. To better understa...

Hurricanes have the ability to export uncharacteristically large amounts of nutrients from terrestrial systems into riverine and estuarine networks, altering rates of ecosystem metabolism throughout the aquatic continuum. In order to explore these impact...

In transitional environments, the role of sediments biogeochemistry and denitrification is crucial for establishing their buffer potential against nitrate (NO3-) pollution. The Po River (Northern Italy) is a worldwide hotspot of eutrophication. However, ...
