Recruitment of coastal planktonic diatoms from benthic versus pelagic cells: Variations in bloom development and species composition
planktonic diatoms benthic vs pelagic cells Variations in bloom development species composition
2014/5/19
Although phytoplankton blooms are major events in aquatic systems, the importance of benthic resting stages in seeding planktonic blooms is still unclear. Using microcosms, we tested the influence of ...
Interannual variation of the isotopic composition of sedimenting organic carbon and nitrogen in Lake Lugano: A long-term sediment trap study
Interannual variation isotopic composition sedimenting organic carbon and nitrogen Lake Lugano long-term sediment trap study
2014/5/14
We examined the evolution of δ13C and δ15N of sedimenting particulate organic matter (SPOM) in response to changes in primary productivity, nutrient loading, and plankton dynamics in Lake Lugano betwe...
Composition and temporal variability of picoeukaryote communities at a coastal site of the English Channel from 18S rDNA sequences
Composition and temporal variability picoeukaryote communities coastal site of the English Channel 18S rDNA sequences
2014/5/14
We analyzed picoeukaryote assemblages at a French coastal site of the English Channel by sequencing cloned eukaryotic 18S rRNA genes in eight genetic libraries constructed from environmental samples (...
Frequency, composition, and causes of summer phytoplankton blooms in a shallow coastal ecosystem, the Kattegat
Frequency omposition summer phytoplankton blooms
2014/5/14
We propose a new operational definition for summer phytoplankton blooms based on station-specific chlorophyll
a distributions. This definition has been applied to a large monitoring...
Influence of inlet bacteria on bacterioplankton assemblage composition in lakes of different hydraulic retention time
bacterioplankton assemblage composition lakes
2014/5/14
The influence of inlet bacteria on the assemblage composition of bacterioplankton was investigated in two Swedish forest lakes of different hydraulic retention time. Assemblage composition of th...
Elemental composition of single cells of various strains of marine Prochlorococcus and Synechococcus using X-ray microanalysis
Elemental composition single cells various strains marine Prochlorococcus Synechococcus X-ray microanalysis
2014/5/21
We measured the elemental composition of single cells from six strains of marine Prochlorococcus and two strains of marine Synechococcus by X-ray microanalysis in the transmission electron microscope ...
Remote assessment of benthic substrate composition in shallow waters using multispectral reflectance
Remote assessment benthic substrate composition shallow waters multispectral reflectance
2014/5/19
We investigated the utility of quantifying percent coverage of benthic substrate constituents from surface multispectral reflectance measurements. Six substrates were considered: kelp, eelgrass, clay,...
A remote sensing method for resolving depth and subpixel composition of aquatic benthos
remote sensing method resolving depth subpixel composition aquatic benthos
2014/5/19
The problem of subpixel heterogeneity in cover types has been addressed in terrestrial environments by the application of linear spectral unmixing techniques. However, in aquatic systems the intercedi...
Quantification, base composition, and fate of extracellular DNA in marine sediments
Quantification, base composition fate of extracellular DNA marine sediments
2014/5/27
The discovery of high concentrations of DNA in marine sediments unaccounted for by living biomass suggests the presence of a large fraction of extracellular DNA, which might play an important role in ...
Stable carbon and nitrogen isotope composition of aquatic and terrestrial plants of the San Francisco Bay estuarine system
Stable carbon nitrogen isotope composition aquatic and terrestrial plants San Francisco Bay estuarine system
2014/5/27
We report measurements of seasonal variability in the C-N stable isotope ratios of plants collected across the habitat mosaic of San Francisco Bay, its marshes, and its tributary river system. Analyse...
The interaction of phytoplankton and bacteria in a high mountain lake: Importance of the spectral composition of solar radiation
phytoplankton and bacteria high mountain lake spectral composition solar radiation
2014/5/26
The role of spectral composition of solar radiation has seldom been considered as a critical factor controlling the algae-bacteria relationship. A coupled algae-bacteria relationship mediated by C rel...
A transplant experiment to identify the factors controlling bacterial abundance, activity, production, and community composition in a eutrophic canyon-shaped reservoir
transplant experiment factors controlling bacterial abundance activity production community composition eutrophic canyon-shaped reservoir
2014/5/26
We performed a transplant experiment in eutrophic Sau reservoir to assess the factors that control bacterial abundance, activity, growth rate, and community composition. Samples from the lacustrine an...
The oxygen isotopic composition of seawater during the Last Glacial Maximum
The oxygen isotopic composition of seawater the Last Glacial Maximum
2014/4/9
High-resolution oxygen and hydrogen isotope measurements were made on pore fluids from deep-sea sediments from sites in the North and South Atlantic. The data provide direct measurements of changes in...
Response of marine bacterial community composition to iron additions in three iron-limited regimes
marine bacterial community iron additions three iron-limited regimes
2014/6/9
In high-nutrient low-chlorophyll (HNLC) regimes, iron additions consistently result in primary productivity increases, and the phytoplankton community shifts from small species toward large diatoms. H...
