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

Post‐Constrained Conditional Sedimentary Facies Simulation From a Single Training Image Using a Concurrent Multi‐Stage Generative Adversarial Network

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract Conditional sedimentary facies modeling enables accurate characterization of the spatial architecture of sedimentary facies, providing crucial support for the fine evaluation and efficient development of natural resources. However, traditional conditional generative adversarial networks (CGANs) often require extensive training data and trade ...

Soil community structure across native and exotic forests is shaped by edaphoclimatic conditions and eukaryotic biomarkers

Journal of Applied Ecology, Volume 62, Issue 11, Page 3128-3141, November 2025.
Our results point to the importance of taking management decisions for these forests considering regional conditions as well as forest type. The provided list of soil keystone taxa should be taken into account in future research and soil monitoring, which is essential for sustainable management of land.

Current Practices for Analyzing Soils and Sediments via Mössbauer Spectroscopy

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 5, Page 742-773, October 2025.
ABSTRACT Environmental scientists are increasingly returning to Mössbauer spectroscopy (MBS) to reveal details about iron (Fe)‐bearing phases in soils and sediments. MBS is particularly powerful at distinguishing between Fe(II) and Fe(III) and, given appropriate background information, can offer exceptionally precise information on Fe speciation in ...

Phytoplankton Blooms on the Barents Shelf, Svalbard, Associated With the Permian–Triassic Mass Extinction

AGU Advances, Volume 6, Issue 5, October 2025.
Abstract Mid‐ to higher‐latitude shallow marine environments are suggested to serve as refugia for organisms during intervals of rapid environmental change associated with hyperthermals. To understand the role of these environments during hyperthermals, we herein investigate the Permian–Triassic environmental crisis, which led to the most severe mass ...

Cave Dripwater Magnetic Minerals Record Seasonal Rainfall Variability: New Insights From a 5‐Years Field Monitoring in Central China

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Stalagmites provide an invaluable archive at high‐resolution for paleoclimate studies. However, it is challenging to extract independent hydroclimate signals from stalagmites due to the scarcity of reliable hydrological proxies. Although the magnetic parameters of stalagmites have shown great potential in recording regional hydrological ...
