Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

The seabed plays a key role in the marine carbon cycle as a) the terminal location of aerobic
oxidation of organic matter, b) the greatest anaerobic bioreactor, and c) the greatest …

Microplastic (MP) pollution has raised public concerns in recent decades globally due to its
wide global spreading and potential toxicity. Most of existing studies have focused on MP …

Sedimentary habitats cover most of the ocean bottom and therefore constitute the largest
single ecosystem on Earth in spatial coverage. The benthic ecosystem contributes to human …

The three main ecological categories of earthworms (anecic, endogeic, epigeic) are often
used as proxies for functional groups. This is troublesome since they were not designed for …

Macroalgae drive the largest CO2 flux fixed globally by marine macrophytes. Most of the
resulting biomass is exported through the coastal ocean as detritus and yet almost no field …

With 4 to 12 million tons of plastic entering the marine environment each year, plastic
pollution has become one of the most ubiquitous sources of pollution of the Anthropocene …

Microplastics (MPs) are ubiquitous, difficult to degrade, and potentially threatening to
organisms in marine environment, so it is important to clarify the factors that affect their …

Predators continue to be harvested unsustainably throughout most of the Earth's
ecosystems. Recent research demonstrates that the functional loss of predators could have …

Organic carbon processing at the seafloor is studied by biogeochemists to quantify burial
and respiration, by organic geochemists to elucidate compositional changes and by …
