Diazotrophic unicellular cyanobacteria in the northwestern Mediterranean Sea: A seasonal cycle
Diazotrophic unicellular cyanobacteria
2014/4/18
Unicellular diazotrophic cyanobacteria (UCYN2-Fix lineage) were detected using whole-cell hybridization of
specific Nitro821 oligonucleotide probe at the coastal and oligotrophic station SOMLIT off M...
Researchers report on new dimension of marine cyanobacteria(图)
marine cyanobacteria new dimension
2014/3/17
Marine cyanobacteria are the tiny ocean plants that form the base of the ocean's food chain. Other organisms feed on them and are nourished by the oxygen they provide.
Short-term displacement of Planktothrix rubescens (cyanobacteria) in a pre-alpine lake observed using an autonomous sampling platform
Planktothrix rubescens lake
2014/4/2
Short-term changes in temporal and spatial distributions of the toxic cyanobacterium Planktothrix rubescens in
Lake Zurich were investigated using high-resolution data sets acquired with an autonomou...
Cyanobacteria as a carbon source for zooplankton in eutrophic Lake Taihu, China, measured by 13C labeling and fatty acid biomarkers
Cyanobacteria carbon source zooplankton eutrophic Lake Taihu China measured by 13C labeling fatty acid biomarkers
2014/4/4
Using a combined stable-isotope and fatty-acid approach, we examined carbon-transfer routes from the cyanobacterium Microcystis to zooplankton in eutrophic Lake Taihu, China. Microcystis is generally ...

Settling blooms of filamentous cyanobacteria as food for meiofauna assemblages
Settling blooms filamentous cyanobacteria as food meiofauna assemblages
2014/4/21
Summer blooms of filamentous nitrogen-fixing cyanobacteria in the Baltic Sea are normally dominated by Aphanizomenon sp. and the toxin-producing Nodularia spumigena. In a 2-week laboratory experiment,...
The cyanate utilization capacity of marine unicellular Cyanobacteria
The cyanate utilization capacity marine unicellular Cyanobacteria
2014/4/21
Cyanate, a by-product of urea decomposition, is a potential nitrogen (N) source in marine environments, but to date it has received scant attention. Cyanobacteria presumably acquire this compound via ...
Nutritional constraints at the cyanobacteria–Daphnia magnainterface: The role of sterols
Nutritional constraints the cyanobacteria–Daphnia magnainter face sterols
2014/4/21
In past decades, a considerable amount of research has been conducted to elucidate the factors that affect the carbon transfer across the cyanobacteria–Daphniainterface. It is well accepted that cyano...

Nitrogen-fixation strategies and Fe requirements in cyanobacteria
Nitrogen-fixation strategies Fe requirements
2014/4/22
Diazotrophic (nitrogen-fixing) cyanobacteria are important contributors of new nitrogen to oligotrophic
environments and greatly influence oceanic productivity. We investigated how iron availability ...
Competition and facilitation between unicellular nitrogen-fixing cyanobacteria and non–nitrogen-fixing phytoplankton species
Competition facilitation unicellular nitrogen-fixing
2014/4/22
Recent discoveries show that small unicellular nitrogen-fixing cyanobacteria are more widespread than
previously thought and can make major contributions to the nitrogen budget of the oceans. We comb...
Nitrogen fixation by unicellular diazotrophic cyanobacteria in the temperate oligotrophic North Pacific Ocean
Nitrogen fixation unicellular diazotrophic cyanobacteria temperate oligotrophic North Pacific Ocean
2014/4/22
N2 fixation has been understudied in marine environments outside of the subtropical and tropical oceans and where water temperatures are typically below 20-25°C. We identified nifH phylotypes and meas...
