An evaluation of iron bioavailability and speciation in western Lake Superior with the use of combined physical, chemical, and biological assessment
iron bioavailability western Lake Superior
2014/4/18
An iron-dependent cyanobacterial bioreporter (Synechococcus strain KAS101) was used in unison with sizefractionated iron content (.0.45, ,0.45, ,0.02 mm), and chemical characterization of iron complex...
Relative roles of coastal and oceanic processes in determining physical and chemical characteristics of an intensively sampled nearshore system
Relative roles of coastal oceanic processes
2014/4/22
We compared the extent to which offshore and remote-sensing measurements of sea surface temperature (SST),
upwelling, and chlorophyll a (Chl a) were concordant with in situ measurements of temperatur...
A new numerical technique for tracking chemical species in a multisource, coastal ecosystem applied to nitrogen causing Ulva blooms in the Bay of Brest (France)
tracking chemical species multisource
2014/4/30
A new numerical technique is presented that allows the tracking of any chemical element from any source in a
simulated foodweb, for instance assessing the proportion of these sources (river loadings,...
Physical, chemical, and biotic effects on arctic zooplankton communities and diversity
Physical chemical biotic effects
2014/5/16
We examined how physical and chemical factors and fish populations affected the presence and density of
zooplankton species in 104 Alaskan arctic lakes. Five fish species and nine zooplan...
Biotic, chemical, and morphometric factors contributing to winter anoxia in prairie lakes
Biotic chemical morphometric factors
2014/5/21
To assess how features of lakes and their watersheds influence winter oxygen decay rates and the frequency of
anoxia in shallow prairie lakes, we measured lake and watershed characteristics for...
Chemical defense in the microplankton I: Feeding and growth rates of heterotrophic protists on the DMS-producing phytoplankter Emiliania huxleyi
Chemical defense Feeding growth rates
2014/5/20
In this study, the hypothesis that Emiliania huxleyi, a cosmopolitan, bloom-forming coccolithophorid, produces
chemical defenses against protist grazers was tested using four axenic strains of the al...
Chemical defense in the microplankton II: Inhibition of protist feeding by b-dimethylsulfoniopropionate (DMSP)
Chemical defense protist feeding
2014/5/20
Examples of chemical defenses and their influence on predator–prey interactions abound in the terrestrial and
marine benthic ecological literature. In contrast, considerably less is known about...
On the usefulness of bilateral comparison to tracking turbulent chemical odor plumes
bilateral comparison racking turbulent chemical odor plumes
2014/6/9
This article reports on the usefulness of bilateral comparison of chemosensory information to an animal or agent
tracking an odor to its source. Instantaneous concentration fields of a chemical...
Orientation in complex chemical landscapes: Spatial arrangement of chemical sources influences crayfish food-finding efficiency in artificial streams
complex chemical landscapes chemical sources infl uences
2014/5/30
Fluid dynamics has been shown to alter ecologically important behaviors of aquatic organisms orienting to distant
chemical sources. Because the fluid dynamics and chemical plumes change across ...
