The Influence of Green Manure Planting on the Spectroscopic Characteristics of Dissolved Organic Matter in Freshwater-Leached Saline–Alkali Soil at Different Depths

Agronomy
This study investigated the influence of green manure planting on the spectroscopic properties of dissolved organic matter (DOM) in saline–alkali soil under freshwater leaching conditions at different soil depths.

Global Change Reshapes Biosynthesis of LC‐PUFA in Northern Lake Food Webs

Global Change Biology, Volume 32, Issue 8, August 2026.
Global change reshapes northern lake conditions, reducing edible phytoplankton LC‐PUFA production. Across 643 lakes, warming, eutrophication, and browning limit dietary LC‐PUFA, forcing zooplankton and fish to rely more on endogenous bioconversion.

Dinoflagellate responses to nutrients and mangrove leaf organic matter in the bioluminescent Mangrove Lagoon, St. Croix, U.S. Virgin Islands

Journal of Phycology, Volume 62, Issue 4, Page 1240-1250, August 2026.
Abstract Bioluminescent bays (biobays) are uncommon coastal ecosystems featuring dense populations of dinoflagellates, often found in mangrove‐ringed lagoons with long water retention times and high organic matter (OM) levels. Although mangroves are associated with high dinoflagellate abundance, it remains uncertain how inorganic nutrients compare with

Polystyrene microplastics facilitate formation of refractory dissolved organic matter and reduce CO2 emissions

Environment International
Microplastics, as a type of anthropogenic pollution in aquatic ecosystems, affect the carbon cycle of organic matter. Although some studies have investigated the effects of microplastics on dissolved organic matter (DOM), the impact of alterations in the

River channel connectivity shifts metabolite composition and dissolved organic matter chemistry

Nature Communications, 2019
The underlying mechanisms structuring dissolved organic matter (DOM) composition and reactivity in rivers remain poorly quantified. Here, the authors pair mass spectrometry and fluorescence spectroscopy to show that hydrology and river geomorphology both

Cryptic Interactions in a Marine Microcosm: Sponges Shape the Microbiome of a Resident Goby

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Microbial symbionts influence ecological and evolutionary processes in their multicellular hosts; yet they remain poorly characterised in marine systems. Sponges host exceptionally diverse microbiomes, potentially providing rich microbial reservoirs for their residents.

Drivers of dissolved organic matter processing in subterranean estuaries

Limnology and Oceanography Letters
Subterranean estuaries (i.e., seawater‐fresh groundwater mixing zones at coastal aquifers) are highly reactive boundaries between continental groundwater and coastal surface seawater.

Molecular characterization of dissolved organic matter (DOM) in seawater

, 2000
Dissolved organic matter (DOM) plays an important role in the global carbon cycle (chapter 1). However, not much is known about the molecular composition and the origin of DOM. The study described in this thesis was conducted to gain more knowledge on the molecular composition and the origin of DOM.

Treeline displacement may affect lake dissolved organic matter processing at high latitudes and altitudes

Nature Communications
Climate change induced shifts in treeline position, both towards higher altitudes and latitudes induce changes in soil organic matter. Eventually, soil organic matter is transported to alpine and subarctic lakes with yet unknown consequences for ...
