Long‐Term Operation of Photovoltaic Power Stations Promotes Soil Carbon Sequestration but Induces Stoichiometric C:N:P Imbalance in Desert Ecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Soil carbon‐nitrogen‐phosphorus (C:N:P) stoichiometry governs nutrient cycling and carbon sequestration in desert ecosystems, yet how large‐scale photovoltaic (PV) deployment, a cornerstone of global carbon neutrality, shifts these stoichiometric balances and whether such shifts enhance or degrade long‐term land function remain unresolved over

Long‐Term Nitrogen Addition Weakens the Linkage Between Phosphorus Cycling Gene Abundance and Phosphatase Activity Through Soil Acidification in a Larix gmelinii Plantation

Land Degradation &Development, EarlyView.
ABSTRACT Anthropogenic nitrogen (N) enrichment propels global forest ecosystems toward phosphorus (P) limitation, theoretically triggering the upregulation of microbial P‐acquisition capacity to maintain stoichiometric balance. However, the extent to which N addition regulates this adaptive capacity remains uncertain.

Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

Introducing a ramped pyrolysis/oxidation‐14CO2 analysis system operated with mobile molecular sieve traps

Limnology and Oceanography: Methods, EarlyView.
Abstract A novel instrument for the thermal degradation of sedimentary organic matter was set up at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with the aim of enabling Ramped Pyrolysis/Oxidation‐14C analysis as direct CO2 gas measurement.
