Warming enhances protozooplankton top‐down control and nutrient competition

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Protozooplankton regulate microbial food webs through top‐down control and nutrient cycling, yet their grazing impacts under ocean warming, particularly in subsurface chlorophyll maximum (SCM) layers, remain poorly understood. This study investigated spatial and seasonal variability in protozooplankton grazing in the northern East China Sea ...

Carbon source and weather in coastal North Carolina

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract The increasing frequency of extreme weather events, including tropical cyclones, is altering the delivery and quality of organic matter (OM) exported from landscapes to estuaries. However, the mechanisms regulating these shifts, especially during multi‐year climatic oscillations, remain poorly understood.

Flood facilitates cross‐ecosystem trophic subsidies to marine animals

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Trophic subsidies are resources that cross ecosystem boundaries, influencing the structure and function of recipient food webs. Widespread regulation of rivers for human consumptive use has profoundly altered natural flow regimes, decoupling donor‐recipient dynamics between freshwater and marine ecosystems. We explored trophic subsidies to the

Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

Limnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

People and Nature, Volume 8, Issue 6, Page 1957-1973, June 2026.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

The Shrinking Caspian Sea: Eco‐Hydrological Responses to Human and Climate Pressures

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood.

Organic Matter Stoichiometry Regulates the Continental Shelf Carbon Pump Efficiency of the Northwest European Shelf Seas

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Variations in the elemental C:N:P ratios of organic matter (OM) influence the coupling of carbon and nutrient cycles in the ocean. In this study, we assess the relevance of OM C:N:P stoichiometry for regional carbon cycling in the northwest European shelf seas (NWES).

Time‐Varying Cycling Rates of Size‐fractionated Particulate Organic Carbon During the Decay of a North Atlantic Spring Bloom

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract The concentrations of particulate organic carbon (POC) in the ocean are the result of a dynamic balance between multiple sources and sinks. Here, measurements of POC concentration in the small size fraction (SSF; 1–5 μm ${\upmu }\mathrm{m}$) and the large size fraction (LSF; >5μm ${ >} 5\ {\upmu }\mathrm{m}$) from the North Atlantic EXport ...

Trace Metal Biogeochemistry in the Nordic Seas: Arctic and Atlantic Water Inflows Determine (Micro)Nutrient Availability

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract We present a data set of macronutrient and dissolved and total dissolvable trace metal concentrations collected in June 2012 across the Nordic Seas. Surface water and depth profiles of manganese, iron, cobalt, nickel, copper, zinc, phosphate, silicic acid, and NOx (nitrate + nitrite) reveal how warm saline Atlantic waters and cold fresh Arctic

Dissolved Organic Matter (DOM) Dynamics at the Sediment‐Water Interface in the North Sea: Implications for Global Benthic DOM Fluxes

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Sediment–water exchange of dissolved organic matter (DOM) represents a critical yet poorly constrained component of the marine carbon cycle. Here, we combine quantitative, molecular, and carbon isotope (δ13C and F14C) analyses to investigate the production, composition, and export of porewater DOM in the German Bight, North Sea, and evaluate ...
