Patterns of sarcodine feeding in epipelagic oceanic plankton

Journal of Plankton Research, 1991
The range of in situ prey composition was determined in marine planktonic acanthana, foraminifera and radiolana collected by divers, and quantitatively compared with the prey available, as determined by surface plankton hauls on cruises in the Florida Current, Gulf Stream and Sargasso Sea.

EPIPELAGIC COPEPOD ASSEMBLAGES IN THE WESTERN CARIBBEAN SEA (1991)

Crustaceana, 2000
[Zooplankton samples were collected on a four-month schedule (February, March, May, August 1991) off the eastern coast of the Yucatan Peninsula, westernmost portion of the Caribbean Sea. Taxonomic analysis of the pelagic Copepoda yielded 89 species, Undinula vulgaris, Temora turbinata, and Farranula gracilis being the overall dominant forms.

Acoustic characteristics of populations of epipelagic schooling fish

The Journal of the Acoustical Society of America, 1976
Pelagic schooled fish populations have acoustic characteristics derived from their individual reflection or backscattering properties, their tendency to school, the tendency of schools to be aggregated in groups, and the tendency for populations of different species to be aggregated in regions of high productivity.

Epipelagic mesozooplankton dynamics around the Mascarene Plateau and Basin, Southwestern Indian Ocean

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2005
It has been suggested that the obstruction of the South Equatorial Current by the Mascarene Plateau might cause upwelling, nutrient enrichment and enhanced chlorophyll and secondary production levels downstream. A study conducted in April and May 2001 showed variability in biomass and community structure which appeared to support this hypothesis but ...

Concealment in epipelagic pterotracheid heteropods (Gastropoda) and cranchiid squids (Cephalopoda)

Journal of Zoology, 1986
Epipelagic pterotracheid heteropods and young cranchiid squids rely primarily on transparency for concealment; yet they have opaque structures, the eyes and visceral organs that compose the visceral nuclei, which can only be camouflaged in other ways. These two groups have achieved convergent solutions to this problem. The visceral nucleus has a narrow

Epipelagic nekton of the North Pacific Subarctic and Transition Zones

Progress in Oceanography, 1999
Abstract During the 1980s and 1990s, scientific research cruises and commercial gillnet operations with scientific observers aboard were conducted throughout much of the Subarctic and Transition Zones of the North Pacific Ocean. These studies produced one of the most extensive databases ever collected on the relative species composition and trophic ...

Life cycle strategies of epipelagic copepods in the Southern Ocean

Journal of Marine Systems, 1998
Twelve epipelagic copepod species were reviewed to compare their adaptations to the short primary production season and low temperatures which characterise the Southern Ocean. The species show a spectrum of adaptations, but three broad life cycle strategies were defined: (1) herbivorous in summer, a short reproductive period and winter diapause at ...

Predation by the epipelagic heteropod mollusk Carinaria cristata forma japonica

Marine Biology, 1980
In surface waters off Southern California (USA), Carinaria cristata forma japonica van der Spoel, 1972 feeds on a variety of zooplankton, although thaliaceans, chaetognaths, and copepods predominate numerically in the diet. Feeding intensity is greatest on the most abundant of two species of thaliaceans, depending on which one dominates in the plankton
