A comparative study of responses in planktonic food web structure and function in contrasting European coastal waters exposed to experimental nutrient addition [PDF]

open access: yes, 2006
We quantify, compare, and generalize responses of experimental nutrient loadings (LN) on planktonic community structure and function in coastal waters. Data were derived from three mesocosm experiments undertaken in Baltic (BAL), Mediterranean (MED), and

Contrasting Responses of Oceanic and Coastal Synechococcus to Iron Limitation and Warming Interactions

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Oceanic Synechococcus respond to the interactive effects of iron (Fe) limitation and ocean warming by regulating photosynthesis, nutrient metabolism, and heat shock gene expression, while a coastal strain has fewer regulatory mechanisms. The oceanic strain may be a superior competitor with more comprehensive and flexible responses in Fe‐poor ...

Proteomic and biogeochemical perspectives on cyanobacteria nutrient acquisition – Part 1: Zonal gradients in phosphorus and nitrogen acquisition and stress revealed by metaproteomes of Prochlorococcus and Synechococcus [PDF]

open access: yesBiogeosciences
Ocean productivity is maintained by key nutrients, including nitrogen, phosphorus and trace metals. The magnitude and stoichiometry of nutrient fluxes to the ocean is changing.

Productivity regime and phytoplankton size structure in the tropical and subtropical North Atlantic in spring 1989 [PDF]

open access: yes, 1993
Productivity regime and phytoplankton size structure are described for two different epipelagic systems in the tropical/subtropical Northeast Atlantic Ocean investigated during 9–11 day drift studies in spring 1989 in the JGOFS North Atlantic Bloom ...

Synechococcus in the Atlantic Gateway to the Arctic Ocean [PDF]

open access: yes, 2016
Increasing temperatures, with pronounced effects at high latitudes, have raised questions about potential changes in species composition, as well as possible increased importance of small-celled phytoplankton in marine systems.

The Role of Viruses in Structure and Functioning of Microbial Communities in Freshwater Ecosystems [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2013
The role of viruses in structure and functioning of microbial communities of plankton, epiphyton and benthos in freshwater ecosystems is discussed. The analysis of own and published data demonstrates that viruses are stable and numerous component of ...

Toxic Cyanobacteria Aerosols: Tests of Filters for Cells [PDF]

open access: yes, 2015
Aerosolization of toxic cyanobacteria released from the surface of lakes is a new area of study that could uncover a previously unknown route of exposure to toxic cyanobacteria.

Spatial differences in dissolved silicon utilisation in Lake Baikal, Siberia: examining the impact of high diatom biomass events and eutrophication [PDF]

open access: yes, 2018
Recent research has highlighted how Lake Baikal, Siberia, has responded to the direct and indirect effects of climate change (e.g., ice-cover duration), nutrient loading, and pollution, manifesting as changes in phytoplankton/zooplankton populations ...

Characterization of photoautotrophic picoplankton assemblages in turbid, alkaline lakes of the Carpathian Basin (Central Europe)

open access: yesJournal of Limnology, 2009
The photoautotrophic picoplankton (PPP) of ten shallow, hyposaline soda lakes located in three different geographical regions in the Carpathian Basin (Central Europe) was characterized. These lakes, which frequently dry out completely, are extremely rich

Carbonate sedimentation and effects of eutrophication observed at the Kališta subaquatic springs in Lake Ohrid (Macedonia) [PDF]

open access: yes, 2010
To date, little is known about the role of spring waters with respect to authigenic carbonate precipitation in a shallow lacustrine setting. Lake Ohrid, located in Southeastern Europe, is a large lake fed to over 50% by karstic springs of which half ...
