Element stoichiometries of individual plankton cells collected during the Southern Ocean Iron Experiment (SOFeX)
Element stoichiometries individual plankton cells collected Southern Ocean Iron Experiment SOFeX
2014/5/19
During the Southern Ocean Iron Experiment (SOFeX), we analyzed Si, P, S, Mn, Ni, and Zn in individual diatoms, autotrophic flagellates, and heterotrophic flagellates with synchrotron-based X-ray fluor...
Circadian cycles in growth and feeding rates of heterotrophic protist plankton
Circadian cycles growth and feeding rates heterotrophic protist plankton
2014/5/19
Growth and feeding rates of four species of planktonic marine heterotrophic protists showed pronounced diel cycles. In most cases, rates were higher during the day and lower at night. However, for the...
The biological availability of Fe has been demonstrated to strongly influence both primary and secondary production in pelagic as well as coastal upwelling high-nutrient low-chlorophyll (HNLC) r...
Biodiversity in metacommunities: Plankton as complex adaptive systems?
Biodiversity metacommunities complex adaptive systems
2014/5/16
One of the more intriguing and challenging developments in ecology and in limnology and oceanography is the
expansion of the temporal and spatial scales that are being addressed by current work. Rese...
A comparison of egg-bank and long-term plankton dynamics of two Daphnia species, D. hyalina and D. galeata: Potentials and limits of reconstruction
egg-bank and long-term plankton dynamics two Daphnia species, D. hyalina and D. galeata Potentials and limits of reconstruction
2014/5/21
Resting eggs of planktonic organisms from datable sediment cores are increasingly used to reconstruct historical information on the abundance, size, genetic composition, and microevolution of plankton...
Beyond bulk properties: Responses of coastal summer plankton communities to nutrient enrichment in the northern Baltic Sea
Beyond bulk properties coastal summer plankton
2014/5/20
Enclosure experiments with all combinations of NH4
and PO4
treatments were carried out in the northern Baltic
coastal zone during the post–spring bloom growth season. Empirical models were used to ...
Bioavailability of DON from natural and anthropogenic sources to estuarine plankton
Bioavailability of DON from natural anthropogenic sources estuarine plankton
2014/5/26
Utilization of dissolved organic nitrogen (DON) from natural (forests) and anthropogenic (animal pastures, urban/suburban storm water runoff) sources (three sites per source) by estuarine plankton com...
Grazerresource interactions in the plankton: Are all daphniids alike?
resource interactions plankton all daphniidae alike
2014/6/10
Daphniids have long been considered to be uniquely effective grazers in the planktonic food web of lakes, but whether all daphniid species are equivalent in this functional role is less clear. In part...
Latitudinal variation of the balance between plankton photosynthesis and respiration in the eastern Atlantic Ocean
Latitudinal variation plankton photosynthesis respiration eastern Atlantic Ocean
2014/6/10
A knowledge of the balance between plankton gross primary production (GPP) and community respiration (CR) in the open ocean is vital to the accurate determination of the global carbon cycle, yet the p...
Responses of Zn assimilation by coastal plankton to macronutrients
Zn assimilation coastal plankton macronutrients
2014/6/9
We examined the Zn uptake in marine diatoms and its transfer to marine copepods under different nutrient-replete and -deplete conditions. Zn uptake, quantified by measurements of both total cellular a...
Bioavailability of natural colloid-bound iron to marine plankton: Influences of colloidal size and aging
natural colloid-bound iron marine plankton
2014/5/30
Iron (Fe) is mostly complexed with the organic ligands or colloids that are very abundant in natural seawater. In
this study, natural colloids were isolated by ultrafiltration and radiolabeled ...
Asymmetric mixing transport: A horizontal transport mechanism for sinking plankton and sediment in tidal flows
sinking plankton sediment tidal fl ows
2014/5/30
A mechanism is described for the net horizontal transport of sinking plankton or sediment by oscillatory tidal
flows. The mean motion of the plankton or particles is driven by the modulation of...
Size structure and the production/respiration balance in a coastal plankton community
Size structure production/respiration balance coastal plankton community
2014/6/9
The quantitative significance of contributions by the picoplankton (,3 mm) to gross primary production (P) and community respiration (R) was investigated seasonally in the plankton community of Chesap...
