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...
Acoustical Sensing of Small-Scale Vertical Structures in Zooplankton Assemblages
Small-Scale Vertical Structures Zooplankton Assemblages
2015/8/6
Observation of aquatic animals in their natural environments remains a major challenge in both biological oceanography and limnology. Critical processes in feeding, reproduction, growth, and predation...
Simultaneous Imaging of Phytoplankton and Zooplankton Distributions
Phytoplankton Zooplankton Distributions
2015/8/6
Understanding the dynamics of the relationship between phytoplankton and higher trophic levels is necessary for understanding the transfers of matter and energy through planktonic food webs. There hav...
Supply-Side Ecology and the Response of Zooplankton to Climate-Driven Changes in North Atlantic Ocean Circulation
Response of Zooplankton Supply-Side Ecology
2015/7/29
Recent findings from oceanographic field studies conducted on both sides of the North Atlantic have dramatically altered our view of how zooplankton populations respond to climate-driven changes in oc...
Climate Impacts on Zooplankton Population Dynamics in Coastal Marine Ecosystems
Global ocean ecosystem dynamics zooplankton predators Marine ecosystems reproduction
2015/7/16
The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental co...
Estimating Zooplankton Biomass Distribution in the Water Column Near the Endeavour Segment of Juan de Fuca Ridge Using Acoustic Backscatter and Concurrently Towed Nets
Estimating Zooplankton Biomass Water Column Near Endeavour Segment Juan de Fuca Ridge Acoustic Backscatter Concurrently Towed Nets
2015/7/14
Logistical challenges, time, and the cost of towed net surveys make it difficult to obtain estimates of secondary biomass and production in the open ocean outside the summer sampling season. Alternate...
Examining shifts in zooplankton community variability following biological invasion
Examining shifts zooplankton community variability following biological invasion
2014/4/2
We examined 20 yr of zooplankton samples from Harp Lake for shifts in zooplankton variability following invasion by zooplankton predator Bythotrephes longimanus, using organism body size—as measured a...
Midwater zooplankton and suspended particle dynamics in the North Pacific Subtropical Gyre: A stable isotope perspective
North Pacific Subtropical Gyre Midwater zooplankton
2014/4/2
We used amino acid (AA) compound-specific isotope analysis (d15NAA and d13
CAA values) of midwater
zooplankton and suspended particles to examine their dynamics in the mesopelagic zone. Suspended pa...
Patch exploitation by planktivorous fish and the concept of aggregation as an antipredation defense in zooplankton
zooplankton antipredation defense
2014/4/2
Contrary to the suggestion that swarming can be used as an antipredation defense in zooplankton, the
individual risk of a planktonic prey (Daphnia) increased rather than decreased with prey density u...
I compiled literature on zooplankton body composition, from protozoans to gelatinous plankton, and report
allometric relations and average body composition. Zooplankton segregate into gelatinous and ...
Zooplankton fecal pellet flux in the abyssal northeast Pacific: A 15 year time-series study
Zooplankton fecal pellet flux time-series study
2014/4/2
Sinking particulate material collected in sequencing sediment traps moored at 3500 m depth (600 m above
bottom) from 1993 to 2008 at the abyssal time-series Sta. M in the northeast Pacific was analyz...
Cyanobacteria as a carbon source for zooplankton in eutrophic Lake Taihu, China, measured by 13C labeling and fatty acid biomarkers
Cyanobacteria carbon source zooplankton eutrophic Lake Taihu China measured by 13C labeling fatty acid biomarkers
2014/4/4
Using a combined stable-isotope and fatty-acid approach, we examined carbon-transfer routes from the cyanobacterium Microcystis to zooplankton in eutrophic Lake Taihu, China. Microcystis is generally ...

Eurytemora affinis(Copepoda) were fed 15N-labeledRhodomonas salina(Cryptophyta) or 15N-labeled Nodularia spumigena(Cyanobacteria) in excess under controlled laboratory conditions. Zooplankton collecte...
Internalwavesandmixingin theepilimnionof a lake affects spatial patterns of zooplankton in a body-size dependent manner
stratifi cation, wind, plankton distribution
2014/4/1
Zooplankton are not uniformly distributed in space but are patchy at multiple scales as a result of
interactions between their directed motion and both large- and small-scale water currents. Using &#...
