The Effect of Hydrostatic Pressure Fields on the Dispersion Characteristics of Fluid-shell Coupled System
hydrostatic pressure dispersion fluid-shell coupled system wave propagation
2011/9/9
The effect of hydrostatic pressure on the vibration dispersion characteristics of fluid-shell coupled structures was studied. Both fluid-loaded cylindrical shells and fluid-filled cylindrical shells w...

Upstream resource abundance determines the food searching behavior of a stream grazer: Effect of microalgal cues
Upstream resource abundance determines searching behavior
2014/4/18
To maximize their growth, grazers should shift their behavior to balance the cues from predators and
periphyton in the field. As a stream grazer seeks periphyton that are heterogeneously distributed,...
Increased supply of ambient nitrogen has minimal effect on salt marsh bacterial production
Increased supply of ambient nitrogen salt marsh
2014/4/18
We examined the role of chronic low-level nutrient enrichment on the productivity of heterotrophic marsh
bacteria via a marsh fertilization experiment in which we mimicked the conditions of widesprea...
Effect of zooplankton-mediated trophic cascades on marine microbial food web components (bacteria, nanoflagellates, ciliates)
zooplankton-mediated trophic marine microbial food
2014/4/17
To examine the grazing effects of copepod-dominated mesozooplankton on heterotrophic microbial
communities, four mesocosm experiments using gradients of zooplankton abundance were carried out at a
c...
Effect of varying calcium concentrations and light intensities on calcification and photosynthesis in Emiliania huxleyi
varying calcium concentrations light intensities
2014/4/22
Various protective and metabolic functions for coccolithophore calcification have been proposed such as
providing a means to supply CO2
for photosynthesis. It has also been speculated that calcifica...
Kinetic isotope effect and biochemical characterization of form IA RubisCO from the marine cyanobacterium Prochlorococcus marinus MIT9313
Kinetic isotope effect biochemical characterization
2014/4/22
In an effort to better understand the factors influencing carbon fixation by Prochlorococcus, and to elucidate
the effects of these cyanobacteria on the ocean carbon cycle, the kinetic parameters and...
Benthic solute exchange and carbon mineralization in two shallow subtidal sandy sediments: Effect of advective pore-water exchange
Benthic solute exchange carbon mineralization
2014/4/22
We conducted four field campaigns to evaluate benthic O2
consumption and the effect of advective pore-water
flow in nearshore permeable sediments in the North Sea and Baltic Sea. Advective pore-wate...
The effect of hydrodynamics on the mass transfer of dissolved inorganic carbon to the freshwater macrophyte Vallisneria americana
hydrodynamics dissolved inorganic carbon
2014/5/5
The combined effects of water velocity (U) and dissolved inorganic carbon (DIC) concentration on
photosynthesis rates of Vallisneria americana were investigated. The net photosynthesis rate or O2 flu...
Effect of eutrophication on the distribution and ecophysiology of the mussel Mytilus trossulus (Bivalvia) in southern Baltic Sea (the Gulf of Gdan′sk)
distribution ecophysiology
2014/4/30
The effect of eutrophication on benthos is usually reported as negative. In the case of the Gulf of Gdan′sk,
eutrophication has increased the availability of food resources to filter feeders su...
Testing the effect of CO2 concentration on the dynamics of marine heterotrophic bacterioplankton
CO2 concentration marine heterotrophic bacterioplankton
2014/4/23
To date no study exists that directly addresses changes in dynamics of heterotrophic bacteria in surface waters
in relation to partial pressure of CO2
(pCO2
). Therefore, we studied the effect of c...
Climate effect on food supply to depths greater than 4,000 meters in the northeast Pacific
northeast Pacifi c Climate
2014/4/23
A long time-series study was conducted over 15 yr (1989–2004) to measure particulate organic carbon (POC)
flux as an estimate of food supply reaching .4,000-m depth in the northeast Pacifi...
