The ocean is home to a diverse and metabolically versatile microbial community that
performs the complex biochemical transformations that drive the nitrogen cycle, including …

The prokaryotic and eukaryotic microorganisms that drive the pelagic ocean's
biogeochemical cycles are currently facing an unprecedented set of comprehensive …

Many feedback loops significantly increase warming due to greenhouse gas emissions.
However, not all of these feedbacks are fully accounted for in climate models. Thus …

Most cropland in the United States is characterized by large monocultures, whose
productivity is maintained through a strong reliance on costly tillage, external fertilizers, and …

Anthropogenic activities are altering total nutrient loads to many estuaries and freshwaters,
resulting in high loads not only of total nitrogen (N), but in some cases, of chemically …

The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …

Microbial activity is a fundamental component of oceanic nutrient cycles. Photosynthetic
microbes, collectively termed phytoplankton, are responsible for the vast majority of primary …

Nitrogen is a requisite and highly demanded element for living organisms on Earth.
However, increasing human activities have greatly altered the global nitrogen cycle …

Ocean ecosystems have responded and will continue to respond to climate changes of
different rates, magnitudes, and durations (virtually certain). Human societies depend on …
