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 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...
Changes in microcystin production in cyanobacteria exposed to zooplankton at different population densities and infochemical concentrations
microcystin production cyanobacteria exposed to zooplankton different population densities infochemical concentrations
2014/4/22
We investigated microcystin (MC) production by four cyanobacterial strains (three Microcystis aeruginosa and one Planktothrix agardhii) in response to different grazer densities (direct exposure: zero...
Change in filter-screen morphology and depth selection: Uncoupled responses of Daphnia to the presence of filamentous cyanobacteria
filter-screen morphology depth selection: Uncoupled responses filamentous cyanobacteria
2014/4/21
In many eutrophic lakes, ability to cope with filamentous cyanobacteria is crucial to Daphnia fitness, as the filaments can reduce food intake by interference with food-particle retention. Two basic m...
Influence of the Amazon River plume on distributions of free-living and symbiotic cyanobacteria in the western tropical north Atlantic Ocean
Influence of the Amazon River plume distributions of free-living symbiotic cyanobacteria the western tropical north Atlantic Ocean
2014/4/23
The vertical and horizontal distributions of seven diazotrophic populations in the western tropical north Atlantic (WTNA) Ocean were examined using a nifH DNA quantitative polymerase chain reaction (Q...
Local adaptation of Daphnia pulicaria to toxic cyanobacteria
Local adaptation Daphnia pulicaria toxic cyanobacteria School of Biology, Georgia Institute of Technology,
2014/5/13
We quantified within-species variation in the tolerance of the large, lake-dwelling daphnid, Daphnia pulicaria, to toxic cyanobacteria in the diet. Juvenile growth rates on diets consisting of 100% An...
Bloom formation in heterocystic nitrogen-fixing cyanobacteria: The dependence on colony size and zooplankton grazing
Bloom formation heterocystic nitrogen-fixing cyanobacteria The dependence on colony size zooplankton grazing
2014/5/19
The success of filamentous nitrogen (N)-fixing cyanobacteria in productive, transiently N-limited freshwaters reflects, in large part, their ability to produce and sustain the activities of specialize...
