Comparative assessment of nitrogen fixation rate by 15N2 tracer assays in the South China Sea
Nitrogen fixation is one of the most important sources of new nitrogen in the ocean and thus profoundly affects the nitrogen and carbon...

Molecular phylogenetics and population demographic history of Amphioctopus fangsiao, inferred from mitochondrial and microsatellite DNA markers
Amphioctopus fangsiao (Cephalopoda: Octopodidae) is an important commercial species in the coastal waters of China. In recent years, however, the...

Seven Species in One? DNA Barcoding Reveals High Cryptic Diversity in Ceratoscopelus warmingii (Myctophiformes, Myctophidae) a Circumglobal Mesopelagic Species
In the marine environment, pelagic ecosystems are vast and complex, with their biodiversity still being underestimated. In these regions,...

Solute tracer test quantification of the effects of hot water injection into hydraulically stimulated crystalline rock
When water is injected into a fracture-dominated reservoir that is cooler or hotter than the injected water, the reservoir permeability is expected...

Use of microbial communities to assess the mixing of deep and shallow groundwater: case study from southern China
Proper assessment of mixing with shallow groundwater is key to understanding the state and hydrochemical composition of deep groundwater. Each tracer...

Review: Advances in the methodology and application of tracing in karst aquifers
Tracer methods have been widely used in many fields of environmental and natural sciences, and also in human health sciences. In particular, tracers...

Biofilm-specific uptake does not explain differences in whole-stream DOC tracer uptake between a forest and an agricultural stream
Benthic biofilms are often assumed to control terrestrially-derived dissolved organic carbon (tDOC) uptake in streams. We tested this by comparing 13 C...

Hydrogeochemical and microbial signatures of deep and shallow groundwater near the enhanced geothermal system in response to the earthquake
Earthquakes can potentially change deep and shallow groundwater systems, but groundwater responses to the triggering events are rarely investigated....

Integrated isotope and microbiome analysis indicates dominance of denitrification in N2O production after rewetting of drained fen peat
Peatlands are an important source of nitrous oxide (N 2 O) emissions, which is a potent greenhouse gas and is also involved in the depletion of...

Can green hydrogen production be used to mitigate ocean deoxygenation? A scenario from the Gulf of St. Lawrence
Ocean deoxygenation and expansion and intensification of hypoxia in the ocean are a major, growing threat to marine ecosystems. Measures currently...
