Nitrogen and Phosphorus Controls on Phytoplankton Growth and Bacterioplankton Communities in Wetland Impoundments

Freshwater Biology, Volume 71, Issue 8, August 2026.
ABSTRACT Nutrient enrichment in shallow lakes and ponds can shift systems from clear water, macrophyte dominance to turbid, phytoplankton dominance. Because the identity and threshold of the limiting nutrients vary among sites, system‐specific evidence is needed to guide water quality management. We conducted 3‐day in situ nutrient‐enrichment bioassays

Bacterioplankton community composition in a boreal forest lake [PDF]

FEMS Microbiology Ecology, 1998
The composition of the dominating populations within a bacterioplankton community was investigated in a mesotrophic, boreal forest lake. Composite samples were collected monthly throughout the lake for two years. The community composition was determined by denaturing gradient gel electrophoresis (DGGE) of a polymerase chain reaction (PCR)-amplified ...

Historical contingencies and phage induction diversify bacterioplankton communities at the microscale

Proceedings of the National Academy of Sciences, 2022
In many natural environments, microorganisms decompose microscale resource patches made of complex organic matter. The growth and collapse of populations on these resource patches unfold within spatial ranges of a few hundred micrometers or less, making such microscale ecosystems hotspots of heterotrophic metabolism. Despite the potential importance of

Stimulated bacterioplankton growth and selection for certain bacterial taxa in the vicinity of the ctenophore Mnemiopsis leidyi

Frontiers in Microbiology, 2012
Episodic blooms of voracious gelatinous zooplankton, such as the ctenophore Mnemiopsis leidyi, affect pools of inorganic nutrients and dissolved organic carbon by intensive grazing activities and mucus release.

Assembly processes and co-occurrence relationships in the bacterioplankton communities of a large river system

Ecological Indicators, 2021
The incoming water area of the Central Line Project of the South-to-North Water Diversion comprises the upper reaches of the Han River in China. Bacterioplankton are important members of river ecosystems.

Selenium speciation dynamics in the Baltic and North Seas: Competing influences of marine and terrestrial inputs, biological activity, and redox conditions

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Despite the importance of coastal areas for the transfer of selenium (Se) from rivers to the open ocean and its bioavailability to food webs, dissolved Se concentrations and speciation in these ecosystems remain poorly understood. We conducted a 3‐yr study with monthly water column sampling at five stations spanning from the North Sea to the ...

Datasets of surface water microbial populations from two anthropogenically impacted sites on the Bhagirathi-Hooghly River

Data in Brief, 2020
The Bhagirathi-Hooghly River, part of the River Ganga, flows along densely urbanized areas in West Bengal, India. The River water is extensively used for household activities, human consumption including bathing, social purposes and multifaceted ...

Redox-specialized bacterioplankton metacommunity in a temperate estuary. [PDF]

PLoS ONE, 2015
This study explored the spatiotemporal dynamics of the bacterioplankton community composition in the Gulf of Finland (easternmost sub-basin of the Baltic Sea) based on phylogenetic analysis of 16S rDNA sequences acquired from community samples via ...

Primary productivity coupled to oxic methane production in coastal waters of southern China

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Oxic methane (CH4) production (OMP) occurs in diverse oxygenated surface waters worldwide. However, phytoplankton‐driven OMP in natural marine environments remains poorly documented. During a research cruise in the highly productive southern East China Sea, we measured OMP by incubating phytoplankton‐rich surface waters and found that CH4 ...

Diving deep into the origins of refractory dissolved amino acids in the ocean

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Amino acids are key constituents of marine peptides and proteins and are generally considered biologically labile or semi‐labile, yet their widespread occurrence throughout the ocean suggests bioresistance over extended timescales. To investigate this paradox, we conducted two parallel shipboard incubation experiments to track microbial ...
