A Synthesis of Viral Contribution to Marine Nitrogen Cycling
Nitrogen is an essential component of major cellular macromolecules, such as DNA and proteins. Its bioavailability has a fundamental influence on the primary production of both terrestrial and oceanic ecosystems. Diverse marine microbes consume nitrogen,

Contrasting responses of the ocean’s oxygen minimum zones to artificial re-oxygenation
Studies assessing potential measures to counteract the marine deoxygenation attributed to anthropogenic activities have been conducted in a few coastal environments and at regional scale, but not yet on a global scale.

Effects of nitrogen addition on root traits and soil nitrogen in the long-term restored grasslands
Fine root traits are plastic and responsive to increased nitrogen (N) deposition. However, with the restoring of the ecosystem after grain for green, little research has been reported about the response of root traits in a long-term restored ecosystem to

Microbial Communities in Vermiculation Deposits from an Alpine Cave
Morgana Cave is located in Val di Scerscen, Central Italian Alps. The cave opens at an altitude of 2,600 m a.s.l. close to the retreating glacier Vedretto di Scerscen, and its entrance was discovered 30 years ago hidden underneath the glacier.

Towards a global interpretation of dual nitrate isotopes in surface waters [PDF]
Modern anthropogenic activities have significantly increased nitrate (NO3-) concentrations in surface waters. Stable isotopes (delta N-15 and delta O-18) in NO3- offer a tool to deconvolute some of the human-made changes in the nitrogen cycle.

NITROGEN CYCLE IN NATURE: POSITIVE AND NEGATIVE EFFECTS [PDF]
This study examines the process of nitrogen cycling in nature, as well as its positive and negative effects on ecosystems. Nitrogen is one of the most common elements in nature, is part of the main biological compounds and is one of the most important ...

A critical trade-off between nitrogen quota and growth allows Coccolithus braarudii life cycle phases to exploit varying environment [PDF]
Coccolithophores have a distinct haplo-diplontic life cycle, which allows them to grow and divide into two different life cycle phases (haploid and diploid).
