Dissolved organic matter (DOM) is recognized for its importance in freshwater ecosystems,
but historical reliance on DOM quantity rather than indicators of DOM composition has led to …

Respiration and leaching are two main processes responsible for soil carbon loss. While the
former has received considerable research attention, studies examining leaching processes …

Fine roots are vital for plant development and carbon biogeochemical cycling in terrestrial
ecosystems. Flooding is known to regulate the physiology and morphology in plant roots; …

To explore the potential role of tetrathionate in the sedimentary sulfur cycle, population
ecology of microorganisms capable of metabolizing this polythionate was revealed at 15–30 …

Marine sedimentation rate and bottom-water O 2 concentration control organic carbon
remineralization and sequestration across continental margins, but whether and how they …

Purpose The coastal environment is a fragile ecosystem exposed to anthropogenic
pressures, including pollution. Microbial ecology studies have demonstrated the importance …

Up to 20% of prokaryotic organisms in the oceans are estimated to die every day due to viral
infection and lysis. Viruses can therefore alter microbial diversity, community structure, and …

Warm winters have recently become common over the Black Sea, leading to the risk of
shoaling oxygen penetration. The insufficient supply of oxygen to the near-bottom layer may …

Sediments underlying marine hypoxic zones are huge sinks of unreacted complex organic
matter, where despite acute O2 limitation, obligately aerobic bacteria thrive, and steady …

Fine roots constitute a fundamental source of litter decomposition and humus formation in
terrestrial ecosystems. However, molecular-level traits of carbonaceous organics in fine …
