Abstract

This paper presents new records of stenothoids from the Scotia Arc (West Antarctic). Altogether twenty species were recorded, two of which are reported in the West Antarctic for the first time. In addition, two species are here recorded for the first time since their description. New data on distribution are supplemented by taxonomical remarks on the collected species.

Abstract

The paper presents a list of over 100 amphipod taxa hitherto recorded in the Admiralty Bay, South Shetlands (Tab. 1). In Tab. 2 the distributional patterns of Amphipoda in upper and middle sublittoral (depth 5-150 m) of the Admiralty Bay are given. Notes on the taxonomy of some taxa are presented.

Abstract

A large sample of more than 1500 individuals of scavenging Amphipoda from fur seal carcass was studied. Six species have been identified. The two most abundant species, Abyssorchomene plebs and Waldeckia obesa, are sublittoral, necrophagous amphipods that could attack the carcass when submerged in the sea. After stranding on the beach they became an attractive food source for birds eating not only the seal tissues but also the scavenging amphipods. The species composition of the present sample as well as earlier data on Antarctic tern stomach content and baited traps taken in the same area and at the same time agreed quite well. These observations confirm the expectation that Antarctic tern feeds on necrophagous amphipods picked out from carcasses stranding on the sea shore.

Abstract

In 1920 qualitative and quantitative benthos samples collected in Barents Sea sublittoral in the years 1951-1983 154 species, 77 genera and 30 families of Amphipoda Gammaridea were identified. Species diversity was highest among the Lysianassidae, Oedicerotidae, Ampcliscidae, Calliopiidae and Pleustidae. Ampelisca eschrichti clearly dominated the material. This same species, plus Haploops setosa and Anonyx nugax were both the most frequently occurring and most numerous species. The distribution of amphipods in the Barents Sea sublittoral varies both in diversity and numbers by region, depth, sediments and water temperature. Zoogeographical changes are discussed in the present paper. Altogether 331 species of amphipods have been hitherto collected in the Barents Sea, of which 317 species, 126 genera and 39 families belong to the suborder Gammaridea.

Abstract

226 taxa (180 identified to species) of benthic invertebrates are recorded from Admiralty Bay on the basis of the material collected by Polish Antarctic Expeditions. Main groups concerned are Folychaeta, Mollusca, Amphipoda and Echinodermata. For each species the bathymetric range, the frequency, the abundance and the geographical distribution are given.
