Grazing and Zooplankton Production as Key Controls of Phytoplankton Production in the Open Ocean
Coast phytoplankton pigment waters physical oceanography
2015/8/17
Thanks to NASA's Coastal Zone Color Scanner (CZCS, 1978-1986), nearly ocean-wide coverage of the distribution of phytoplankton pigment in the upper part of the euphotic zone and, in effect, in the mix...
Ecology of a Chaetoceros socialis Lauder Patch on Georges Bank: Distribution, Microbial Associations, and Grazing Losses
Georges Bank: Distribution Microbial Associations
2015/8/6
The presence of patches and layers in marine pelagic ecosystems may play an important role in providing food for higher trophic levels at concentrations high enough to support the metabolism, growth, ...
Intense Benthic Grazing on Phytoplankton in Coral Reefs Revealed Using the Control Volume Approach
Coral Reefs Revealed Control Volume Approach
2015/8/5
What is our international investment in oceanography, and how has it changed over the years? Two seemingly simple questions that have daunted our community repeatedly. The first of these two questions...
Grazing resistance allows bloom formation and may explain invasion success of Gonyostomum semen
Grazing resistance bloom formation may explain invasion success Gonyostomum semen
2014/4/3
The nuisance alga Gonyostomum semen (Raphidophyceae) has expanded in the Nordic countries during the last decades and can dominate lake phytoplankton communities almost completely. A possible explanat...

Does warming enhance the effect of microzooplankton grazing on marine phytoplankton in the ocean?
warming enhance the effect of microzooplankton grazing marine phytoplankton in the ocean
2014/4/2
We evaluated a hypothesis derived from the metabolic theory of ecology (MTE) that the ratio of microzooplankton herbivory (m) to phytoplankton growth (m) will arise in a warming ocean because of the d...
Local genetic adaptation to grazing pressure of the green algaDesmodesmus armatusin a strongly connected pond system
Local genetic adaptation grazing pressure the green alga Desmo desmus armatusin strongly connected pond system
2014/4/17
Dispersal potentially homogenizes genetic variation among populationsand thus may prevent local genetic adaptation. If selection gradients are strong and the selection responseefficient, however, loca...
Relationships between phytoplankton growth and cell size in surface oceans: Interactive effects of temperature, nutrients, and grazing
phytoplankton growth cell size in surface oceans Interactive effects temperature nutrients grazing
2014/4/17
We compile two data sets from14C uptake and dilution experiments conducted in surface waters of the global ocean to investigate the relationship between phytoplankton mass-specific growth rate and cel...
Intense benthic grazing of phytoplankton in a coral reef
Intense benthic grazing of phytoplankton coral reef
2014/4/18
Grazing on phytoplankton by a section of the fringing coral reef in Eilat, the Gulf of Aqaba, Red Sea, was studied using the control-volume approach, a direct, nonintrusive technique common in enginee...

Close coupling phytoplankton growth microzooplankton grazing
2014/4/18
We conducted 28 dilution experiments during August–September 2007 to investigate the coupling of growth
and microzooplankton grazing rates among ultraphytoplankton populations and the phytoplankton c...

We investigated the population ecology of toxigenic diatoms within the genusPseudo-nitzschiaon the Pacific Northwest coast during 2003, 2004, and 2005.Pseudo-nitzschiaspp. were widespread and abundant...
Chemical defense of the red tide dinoflagellate Karenia brevis against rotifer grazing
Chemical defense red tide dinoflagellate Karenia brevis against rotifer grazing
2014/4/22
In order to test whether phytoplankton such as the red tide dinoflagellate Karenia brevis negatively affect rotifer grazers and what mechanisms are involved in these interactions, we conducted laborat...
