(Oxford University Press, 1985)Primary production, release of extracellular products (EOC) and the distribution of 14C into primary products of photosynthesis (low mol. wt. products, lipids, polysaccarides, and proteins) were investigated during 2 months ...
-
(Oxford University Press, 1994)The δ15N values of micronekton collected from Sagami Bay ranged from 9.4 to 14.2%‰. The 15N values of the micronekton, Gonostoma gracile, increased with growth (9.4 to 12.6%‰) and it seems that males, before sex reversal, ...

-
(Oxford University Press, 1991)Batch culture experiments were performed to test the ability of Phaeocystis sp. to grow on organic phosphates as the only source of phosphorus.Of nine organic phosphates tested seven supported growth equally well as did ...
-
(Oxford University Press, 1989)A bioenergetic model for Mysis growth and consumption is presented and used to calculate seasonal patterns of food consumption by Mysis mixta at two stations in a coastal area of the northern Baltic Sea. Calculated specific ...

(Oxford University Press, 1979-10-01)
-
(Oxford University Press, 1984)The population abundances and rates of biomass production of heterotrophic nanoplankton (HNAN) in Georgia coastal waters were evaluated by epifluorescence microscopy. HNAN populations (mostly non-pigmented microflagellates ...
-
(Oxford University Press, 1995-04-01)The microzooplankton of the Irish Sea (˜54°N 5°W) were investigated by microscope-based image analysis for the late spring-early summer period in 1987, 1988, 1989 and 1992. The microzooplankton community was dominated by ...
-
Abundance, breeding and temporal size distribution of the chaetognath Sagitta setosa in the Kattegat(Oxford University Press, 1983)During a hydrographical survey in the northern Kattegat, 1975 to 1977, vertical plankton hauls were taken monthly at four stations between Göteborg and Frederikshavn. Hydrographical parameters were measured at 10 stations ...
-
(Oxford University Press, 1993)The abundance and sedimentation of acantharia and their cysts was recorded in the water column and sediment traps in the East Greenland Sea in August-September 1990. Although acantharia constituted <1% of total suspended ...
-
(Oxford University Press, 1991)The abundances of acantharians and the carbon fixation rates of their symbiotic algae were measured over an 18 month period at the VERTEX seasonal station, 1400 km west of Monterey, CA. Abundances varied up to 4 1 acantharians ...
-
(Oxford University Press, 1995-12-01)The effects of solar ultraviolet radiation (UVR) on photosynthetic rates of natural assemblages of Antarctic phytoplankton were determined in both 1 day and 2 week incubations during austral spring at Palmer Station, ...
-
(Oxford University Press, 1979-04-01)Cultures of Dunaliella tertiolecta were exposed to five concentrations of cadmium in solution (0.1, 0.5, 1, 5 and 10ppm(mg 1-1)). The accumulation of cadmium by the algae was found to have two phases, an initial rapid ...
-
A change in the pattern of vertical migration of Chaoborus flavicans after the introduction of trout(Oxford University Press, 1986)The pattern of diel vertical migration exhibited by Chaoborus flavicans in Lake Lenore, Washington has changed over the past decade. Formerly Chaoborus larvae and pupae were present in the water column during the day. Since ...
-
(Oxford University Press, 1982)A plankton centrifuge with a capacity of 200 1.h−1 was built from a spin-drier.
-
(Oxford University Press, 1993)The freshwater copepod Skistodiaptomus oregonensis was exposed, in laboratory bioassays, to a 3 × 3 factorial array of pH and aluminum treatments (pH 4.5, 6.0 and 7.5, and 0, 100 or 200 μg l−1 Al). After 12 and 24 h, ...
-
(Oxford University Press, 1992)Triplicate in situ enclosures containing plankton from a small glacial kettle lake were either untreated (pH>8) or were acidified to pH 6.5, 5.5 or 4.5 over 7 days using H2SO4. Plankton size spectra were constructed, in ...
-
(Oxford University Press, 1987)The English umbrella net is a new-design vertical closing net developed to sample zooplankton populations in under-ice environments. Operating on the principle of an umbrella, this wide-mouth net fits through a hole drilled ...
-
(Oxford University Press, 1995-04-01)
-
(Oxford University Press, 1982)Cellular chlorophyll a, protein, carbohydrate and lipid content was determined for eleven clones of centric marine diatoms (volume 89–1.47 × 107 μ3) and eight species of marine dinoflagellates (597–4.45 × 104 μ3) cultured ...
