Heterogeneous oxygenation resulting from active and passive flow in two Mediterranean sponges,Dysidea avaraandChondrosia reniformis
Heterogeneous oxygenation resulting active passive flow in two Mediterranean sponges Dysideaavara Chond rosia reniformis
2014/4/17
The oxygen dynamics and pumping behavior inDysidea avaraand Chondrosia reniformis(Porifera,Demospongiae) were investigated using oxygen microelectrodes and heated thermistor flow sensors. Both field a...
Modeling flow in coral communities with and without waves: A synthesis of porous media and canopy flow approaches
Modeling flow in coral communities with and without waves: A synthesis of porous media and canopy flow approaches
2014/4/21
Both canopy flow and porous media theories have been developed independent of one another to predict flow through submerged porous structures. These approaches are very similar, albeit with some key d...
Tracking carbon flow in a 2-week-old and 6-week-old stream biofilm food web
carbon flow a 2-week-old 6-week-old stream biofilm food web
2014/4/21
We studied the carbon flow of an allochthonous carbon source (sucrose) in abiofilm food web using stable isotope analysis and lipid biomarkers. Initial biofilms were grown for 2 weeks in a third order...
Microzooplankton dominate carbon flow and nutrient cycling in a warm subtropical freshwater lake
Microzooplankton carbon flow nutrient cycling warm subtropical freshwater lake
2014/4/22
In a series of grazer-gradient and dilution microcosm experiments, we compared grazing and nutrient mineralization by naturally co-existing crustacean and microzooplankton assemblages from mesoeutroph...
Boundary layer turbulence and flow structure over a fringing coral reef
Boundary layer turbulence flow structure over fringing coral reef
2014/5/5
Measurements of velocity and rates of turbulence were made across a fringing coral reef in the Gulf of Aqaba, Red Sea, to determine the effect that the rough topography has on boundary layer mixing an...
Virus predation by sponges is a new nutrient-flow pathway in coral reef food webs
Virus predation by sponges new nutrient-flow pathway coral reef food webs
2014/5/4
The removal efficiency of viral particles by the coral reef sponge Negombata magnifica was measured. Virus particles were removed by the sponge at an average efficiency of 23.3% ± 2.9%. Significant am...
Effects of the depth to coral height ratio on drag coefficients for unidirectional flow over coral
Effects of the depth coral height ratio drag coefficients unidirectional flow over coral
2014/5/4
We investigated the effects of the ratio of water depth (H) to coral height (h) on the drag coefficient (Cd) for unidirectional flow over the coral species Porites compressa. Cd, measured in a laborat...
Bioluminescent response of the dinoflagellate Lingulodinium polyedrum to developing flow: Tuning of sensitivity and the role of desensitization in controlling a defensive behavior of a planktonic cell
Bioluminescent response dinoflagellate Lingulodinium polyedrum developing flow Tuning of sensitivity desensitization controlling a defensive behavior planktonic cell
2014/5/9
Dinoflagellate bioluminescence is believed to serve a defensive function, decreasing grazing at night. Previous characterization of bioluminescence stimulated by fully developed flows might have under...
Effects of surface roughness and oscillatory flow on the dissolution of plaster forms: Evidence for nutrient mass transfer to coral reef communities
surface roughness oscillatory flow dissolution of plaster forms nutrient mass transfer coral reef communities
2014/5/8
We dissolved plaster forms in seawater to examine the effects of surface roughness and flow conditions on masstransfer rates. Plaster blocks with varying roughness were dissolved under both steady and...
Growth rates of coastal phytoplankton from time-series measurements with a submersible flow cytometer
coastal phytoplankton time-series measurements submersible flow cytometry
2014/5/21
Our understanding of the dynamics of phytoplankton communities has been limited by the space and timescales associated with traditional monitoring approaches. To overcome some of these limitations, we...
Sequential resuspension of protists by accelerating tidal flow: Implications for community structure in the benthic boundary layer
Sequential resuspension protists accelerating tidal flow community structure benthic boundary layer
2014/5/27
We measured resuspension thresholds of protists and bacteria at a subtidal coastal site with in situ flumes and by sampling the benthic boundary layer during tidal accelerations. Heterotrophic nanofla...
Influences of benthic boundary-layer flow on feeding rates of ciliates and flagellates at the sediment-water interface
benthic boundary-layer flow feeding rates ciliates flagellates sediment-water interface
2014/6/10
Heterotrophic protists are integral to sedimentary food webs, but influences on their activities are poorly understood, especially the role of benthic boundary-layer flow. Effects of flow on ingestion...
Wave action imposes potentially large hydrodynamic forces on intertidal plants and animals, and can act as a primary agent of disturbance. It has also been proposed that rapid water accelerations prod...
