Leeches (Hirudinida: Piscicolidae)--parasites of Antarctic fish from Channichthyidae family.
There has hitherto been very few research projects focusing on ectoparasites of Antarctic fishes. The presently reported study provides data on the prevalence and the intensity of leeches (Hirudinida: Piscicolidae) infecting fishes. The materials were collected in December-February 1986/87 off the Elephant Island, South Georgia, Joinville Island, and South Shetlands. The following leech taxa we...
متن کاملMarine pelagic ecosystems: the west Antarctic Peninsula.
The marine ecosystem of the West Antarctic Peninsula (WAP) extends from the Bellingshausen Sea to the northern tip of the peninsula and from the mostly glaciated coast across the continental shelf to the shelf break in the west. The glacially sculpted coastline along the peninsula is highly convoluted and characterized by deep embayments that are often interconnected by channels that facilitate...

The horizontal and vertical distributions of selected taxa that dcminate the pelagic zooplankton com· munity (> 0.2 mm) within the Palmer Loog-Tenn Ecological Research (LTFR) ItUdy region are described. In addition to a synthesis of existing published descriptions for euphawiids, saIps, and copepods, two newly available datasets are analyud . Recent observations (1991-1994) obtained as part of ...
