Seasonal Variability of Mesozooplankton Feeding Rates on Phytoplankton in Subtropical Coastal and Estuarine Waters
In order to understand how mesozooplankton assemblages influenced phytoplankton in coastal and estuarine waters, we carried out amonthly investigation onmesozooplankton composition at two contrasting stations of Hong Kong coastal and estuarine waters and simultaneously conducted bottle incubation feeding experiments. The assemblage of mesozooplankton was omnivorous at both stations with varying...
متن کاملGrazing by meso- and microzooplankton on phytoplankton in the upper reaches of the Schelde estuary (Belgium/The Netherlands)
In contrast with the marine reaches of estuaries, few studies have dealt with zooplankton grazing on phytoplankton in the upper estuarine reaches, where freshwater zooplankton species tend to dominate the zooplankton community. In spring and early summer 2003, grazing by microand mesozooplankton on phytoplankton was investigated at three sites in the upper Schelde estuary. Grazing by mesozoopla...
متن کاملCoupling between phytoplankton growth and microzooplankton grazing in dilution experiments: potential artefacts
Phytoplankton distribution is relatively constant in large areas of the surface ocean. In order to maintain this apparent stability, phytoplankton production and losses have to be balanced. Indeed, growth (μo) and grazing (g) rates obtained simultaneously with the dilution technique are often tightly coupled. One problem with this approach is that growth and grazing are not independent in the e...
متن کاملMicrozooplankton grazing of phytoplankton in Manukau Harbour, New Zealand
Grazing by microzooplankton on phytoplankton in Manukau Harbour was measured by size-fractionated dilution experiments at monthly intervals from October 1994 to October 1995. Grazing rates were always highest on the < 5 urn size fraction, the smallest size fraction measured. These rates ranged from 0.3 to 1.3 d" and were highest in November and March; values did not appear to vary with grazer a...
متن کاملMicrozooplankton Grazing in Green Water—Results from Two Contrasting Estuaries
We measured seasonal variations in microzooplankton grazing in Long Island Sound (LIS) and San Francisco Bay (SFB). There was consistent evidence of nutrient limitation in LIS, but not SFB. We found higher chlorophyll a concentrations in LIS compared with SFB. In spite of differences in phytoplankton, there were no differences in microzooplankton abundance (summer: LIS, 12.4±1.8×10 indiv.L; SFB...
