Contrasting responses of the ocean’s oxygen minimum zones to artificial re-oxygenation

Environmental Research Letters, 2023
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

Plant, Soil and Environment, 2021
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

An Improved Unmixing-Based Fusion Method: Potential Application to Remote Monitoring of Inland Waters

Remote Sensing, 2015
Although remote sensing technology has been widely used to monitor inland water bodies; the lack of suitable data with high spatial and spectral resolution has severely obstructed its practical development.

Microbial Communities in Vermiculation Deposits from an Alpine Cave

Frontiers in Earth Science, 2020
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.

Effects of nitrogen input on soil bacterial community structure and soil nitrogen cycling in the rhizosphere soil of Lycium barbarum L.

Frontiers in Microbiology, 2023
Lycium barbarum L., goji berry, is a precious traditional Chinese medicine and it is homology of medicine and food. Its growth is heavily dependent on nitrogen.

NITROGEN CYCLE IN NATURE: POSITIVE AND NEGATIVE EFFECTS [PDF]

Vestnik Issyk-Kulʹskogo universiteta
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]

Biogeosciences
Coccolithophores have a distinct haplo-diplontic life cycle, which allows them to grow and divide into two different life cycle phases (haploid and diploid).

Nitrogen removal in marine environments: recent findings and future research challenges [PDF]

, 2005
Respiratory reduction of nitrate (denitrification) is recognized as the most important process converting biologically available (fixed) nitrogen to N2. In current N cycle models, a major proportion of global marine denitrification (50–70%) is assumed to
