Micro and mesozooplankton composition during winter in Ushuaia and Golondrina Bays (Beagle Channel, Argentina)
The current paper analyses the micro and mesozooplankton in Ushuaia and Golondrina Bays, the first research on these plankton fractions of these areas in wintertime (August 2004). The number of microzooplankton and mesozooplankton taxa was higher in Ushuaia Bay than in Golondrina Bay. Aloricate cilia...

| Sumario: | The current paper analyses the micro and mesozooplankton in Ushuaia and Golondrina Bays, the first research on these plankton fractions of these areas in wintertime (August 2004). The number of microzooplankton and mesozooplankton taxa was higher in Ushuaia Bay than in Golondrina Bay. Aloricate ciliates predominated over tintinnids in microzooplankton and holoplankton over meroplankton in mesozooplankton in both bays. Ctenocalanus citer, Drepanopus forcipatus and Clausocalanus brevipes presented the highest frequency of occurrence. Among the meroplankton. Halicarcinus planatus and Munida gregaria were the most frequent decapod larvae in both bays. The distribution of the different sampling station groups of microzooplankton and mesozooplankton as determined by cluster analysis suggests the influence of natural conditions in each bay and anthropogenic environmental differences between the two bays. |
