Limnology and Oceanography, Volume 71, Issue 4, April 2026.Abstract Submarine groundwater discharge (SGD) is a widely recognized pathway for nutrient transport to coastal systems. Prior studies overlook the unique biogeochemical signatures of different SGD pathways, neglecting their differences in biogeochemical transformations and spatiotemporal factors.

Structural Insights into Dissimilatory Sulfite Reductases: Structure of Desulforubidin from Desulfomicrobium Norvegicum [PDF]
, 2011 Dissimilatory sulfite reductases (dSiRs) are crucial enzymes in bacterial sulfur-based energy metabolism, which is likely to have been present in some of the earliest life forms on Earth.

Kinetics of sulfate‐ and iron‐dependent anaerobic methane oxidation in freshwater lake sediment
Limnology and Oceanography, Volume 71, Issue 4, April 2026.Abstract Anaerobic oxidation of methane (AOM) is a potentially important sink for methane in freshwater sediments. Assessing the contribution of AOM to methane budgets requires an understanding of AOM process kinetics, yet such information remains scarce.

Iron Sources and Cycling During Diagenetic Transformations of Negev Phosphorites (Israel)
Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.Abstract The Late Cretaceous Negev area in the Levant was influenced by high productivity upwelling in southern Tethys, leading to massive deposition of phosphorites. The phosphorites occur in two facies: (a) pristine phosphorites with low phosphorous (P) content, formed under low‐energy, high‐productivity conditions, and (b) reworked phosphorites with

Soil Microbiome of Tropical Seasonal and Permanent Small Wetlands
Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.Distinct hydrological regimes shape microbial communities and metabolic pathways in tropical wetlands. Redox‐driven shifts highlight enhanced methanogenesis under anoxia, and dominant archaeal and bacterial groups reflect specific redox conditions and adaptations, with important implications for biogeochemical cycling and climate‐relevant processes ...

Decoupling of sulfur and nitrogen cycling due to biotic processes in a tropical rainforest [PDF]
, 2014 We examined the terrestrial sulfur (S) cycle in the wet tropical Luquillo Experimental Forest (LEF), Puerto Rico. In two previously instrumented watersheds (Icacos and Bisley), chemical and isotopic measurements of carbon (C), nitrogen (N) and S were ...

Food Bioengineering, Volume 5, Issue 1, Page 152-167, March 2026.ABSTRACT The intake of capsaicin can disrupt the gut microecology and impact health, yet its underlying mechanism is not fully elucidated. This study, by establishing capsaicin‐induced human microbiota‐associated (HMA) mouse models revealed the molecular mechanism by which capsaicin perturbs the gut microbiota and metabolites, leading to intestinal ...
