| The variations of zooplankton structure and abundance were studied at short time intervals in the northern part of the West Naubaria Canal, near the sea side, based on weekly sampling from May 2002 to May 2003 .The community represented high species richness (120 species), and relatively low population density ( annual average 31340 organisms/m.3). Freshwater forms were the major representatives (68 species) of the community, including the sea side station. However, several marine species were reported inside the canal at a long distance from the sea. The community structure showed wide weekly variations (4-29 species), while between stations the differences were small. Relative to salinity in the canal, diversity index sustained the highest value (annual... |
