    Notes: Populations of the amphipod, Anisogammarus pugettensis (Dana) 1853, can be raised for several generations under laboratory conditions. Compared with the growth of another amphipod, Eogammarus confervicolus Stimpson 1856, A. pugettensis grew more rapidly to maximum biomass and reached a new generation earlier when both were grown under their optimal growth conditions. A. pugettensis grew faster in upwelled impoundments containing epiphytic diatoms than under laboratory conditions. In fish feeding studies, the amphipod E. confervicolus is an adequate diet for salmonid growth when compared with Oregon moist pellets.

    Notes: [Auszug] The main problem is one of the quantitative collection of particles as small as 1 in diameter from many litres of water. This is solved conveniently by filtration through a membrane 'sieve' filter, such as the 'Millipore' HA or AA filter disks. The difficulty is then one of removing the collected ...

    Photosynthesis and fish production: Hypothetical effects of climatic change and pollution (1977)

    Notes: Abstract Overall comparisons of marine pelagic productions in different systems are speculative to a high degree. Yet they often bring to our attention processes which have not been sufficiently investigated. One such process may be the decrease of fish production due to the change in the diatom/flagellate ratio. The following hypothesis is discussed in the light of recent investigations: An increasing development of flagellates caused by some types of pollution or climatic changes not only may increase the number of trophic levels and thereby, decrease fish production, but also may cause a change in the flow of biomass from fish to ctenophores and other planktonic predators, thereby again decreasing the harvest available for human consumption.

    Frontal zone analysis at the mouth of Saanich Inlet, British Columbia, Canada (1983)

    Notes: Abstract The presence of a biological front at the mouth of an inlet (fjord) on the coast of British Columbia, Canada was established. The presence of the biological front was consistent with physical predictions based on water velocity and depth. The frontal zone was characterized by a high primary productivity and surface chlorophyll. From spectral analysis of data the zone was found to fluctuate under tidal influence so that observations made at a single point showed a 14-d cycle in chlorophyll maxima which was about 180° out of phase with maxima in tidal exchange.

    Production studies in the Mackenzie River — Beaufort Sea estuary (1988)

    Topics: Biology
    Notes: Summary Production studies were carried out in the Mackenzie River/Beaufort Sea estuary during the summer of 1986. Results indicate that there were two plankton communities. One was located near the river mouth and was characterized by high dissolved organic carbon, high bacterial activity and a community of amphipods. The second community was associated with high phytoplankton production off shore and with a community of copepods, hydromedusae and ctenophores. The offshore marine/oceanic community was quantitatively much more productive than the near shore bacterial community during the summer months.

    Impact of predation-disturbance by large epifauna on sediment-dwelling harpacticoid copepods: Field experiments in a subtidal seagrass bed (1991)
    Springer
    Marine biology 109 (1991), S. 485-491 
    Details
    ISSN: 1432-1793
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The hypothesis was tested that predation-disturbance by epibenthic macrofauna affects the abundance of sediment-dwelling harpacticoid copepods. The copepods inhabited a subtidal seagrass (Zostera marina L.) bed in British Columbia, Canada. The response of the harpacticoid community was observed in controlled field experiments in which epibenthic predators-disturbers were excluded from portions of the seagrass bed. Controlled, exclusion-cage (0.8 m2 area, 7-mm mesh) experiments were conducted within the seagrass bed from late March/early April to mid-June in both 1986 and 1987. Sampling was conducted biweekly. Exclusion of large epibenthic predators-disturbers had little effect on sediment-dwelling harpacticoid copepod density. Total harpacticoid numbers and abundances of dominant species generally did not increase in the exclusion treatment relative to the control. Shifts in species composition of the harpacticoid community did not occur. The treatment control was adequate in simulating the exclusion cage structure. It appears that large epibenthic predators-disturbers have little impact on the abundance of harpacticoid copepod populations at this study site.

    Simulation study of phytoplankton photosynthesis and growth in the Fraser River estuary (1973)
    Springer
    Marine biology 19 (1973), S. 102-116

    Topics: Biology
    Notes: Abstract Phytoplankton photosynthesis was estimated by a simulation model of the Fraser River estuary (Canada). For this estimation, two kinds of information were considered; (1) the photosynthetic response of phytoplankton taken from the estuary to each environmental factor; (2) actual measurement of changes in each environmental factor in the estuary. As the major limiting factors, light intensity, temperature, and nitrate were taken into account. Variations in these parameters were combined together under the assumption of the “law of the minimum”; that is, only one of the environmental factors was considered to limit photosynthesis at any given time and place. From the results obtained, it could be shown which environmental factors actually limited phytoplankton photosynthesis in the Fraser River estuary at different times of the year and at different depths.

    Autotrophic and heterotrophic production in the Mackenzie river/Beaufort Sea estuary (1989)
    Springer
    Polar biology 9 (1989), S. 261-266 
    Details
    ISSN: 1432-2056
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Productivity studies in the Mackenzie estuary and Beaufort Sea have confirmed the existence of two food chains based either on autotrophic marine diatoms or on organic material derived from the river. From 13C and 15N isotope studies, it appears that autotrophic production, which reached surface values of 10 mgC/m3/h, was largely responsible for maintaining the herbivorous copepods and a number of important predators including jellyfish, chaetognaths, hyperiid amphipods and some marine fish. The heterotrophic food chain largely supported a population of gammarid amphipods and some anadromous fish. In the summer of 1987, bacterial populations of〉106 cells/ml were encountered in the estuarine waters. These values were much higher than in 1986. It is suggested that this difference was caused by advective processes due to on-shore winds in 1987; other differences between 1986 and 1987 fish populations, near shore temperatures and ice cover were also noted.

    Microbial response to crude oil and Corexit 9527: SEAFLUXES enclosure study (1985)

    Notes: Abstract The response of marine bacteria to Corexit 9527, with and without Prudhoe Bay crude oil labeled withn−(1−14C)hexadecane, in a temperate pelagic environment was monitored over 22 days using controlled ecosystem enclosures. The results indicated that Corexit and Corexit-dispersed crude oil stimulated bacterial production by serving as substrates and/or by inducing the release of organic compounds from the indigenous phytoplankton population. Highest bacterial standing stock was observed in the enclosure treated with a mixture of Corexit and crude oil, in which a large fraction of the predominant bacterivores were eliminated. Biodegradation appeared to be more significant than abiotic processes in contributing to the loss of low volatility n-alkanes in Corexit-dispersed oil. Twenty-two days following its addition, 50% of the radiotracer was recovered: 3% in the suspended particulate fraction, 10% in sedimentary material, 36% as CO2, and less than 1% in the dissolved organic pool.
