Ecosphere, Volume 17, Issue 1, January 2026.Abstract Scleractinian coral evolved under nitrogen (N)‐limited conditions. The increase in N flux from anthropogenic activities to these otherwise N‐depleted environments is threatening coral health and coral reef ecosystem function. We tested the effect of elevated ammonium (NH4+) loading on Acropora metabolism responses (respiration, gross primary ...

Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract Nitrification is a key process in the aquatic nitrogen (N) cycle, but its products, nitrate (NO3−) and nitrous oxide (N2O), contribute to eutrophication and greenhouse gas emissions, particularly in eutrophic lakes. Variations in in‐lake N cycling and N2O production pathways, as a function of seasonality and artificial oxygenation, remain ...

Marginal seas as potential sinks for refractory carbon
Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract The Yellow Sea (YS) and East China Sea (ECS) are marginal seas in the Northwestern Pacific that receive large amounts of aged, terrestrial organic matter. In this study, we measured dissolved organic carbon (DOC) concentrations and radiocarbon contents (Δ14C) in these seas during summer and autumn, extending a previous winter study to provide ...

Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract Benthic microalgal (BMA) communities contribute significantly to food webs, nutrient cycling, and carbon flows in intertidal habitats. However, the contribution of BMA to saltmarsh carbon stocks (“blue carbon”) is unclear. BMA and sediment total organic carbon (TOC) stocks were measured in an east coast American Atlantic saltmarsh, revealing ...

Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract Heterotrophic diazotrophs are potentially important to the nitrogen cycle in freshwater ecosystems, yet their abundance, N2 fixation rates, diversity, and association with aggregates remain poorly understood. This study elucidates the contribution of freshwater heterotrophic diazotrophs as free‐living or aggregate‐associated cells to total N2 ...
