Potential impact of the main benthic amphipods on the eastern Weddell Sea shelf ecosystem (Antarcticinly related to differences in relative amphipod species composition in samples. Presented results will help in refining ecological models of the prospected area, but also underline the need for accurate and reliable measurements of the feeding rates of Antarctic benthic organisms.

Cytogenetics of the bathydraconid fish , (Perciformes, Notothenioidei) from Terra Nova Bay, Ross Seaorrespond to a large region in a single chromosome pair. Mapping of the available karyotypic data on a molecular phylogenetic tree provided information on chromosomal diversification during the cladogenesis of the bathydraconids.

Unexpectedly high abundance and biomass of Amphipoda were observed in the first half of winter (May/July), surpassing otherwise important summer amphipod abundance. The probable reason for this phenomenon could be high autumn abundance of decaying algae on the be

Primary production, light and vertical mixing in Potter Cove, a shallow bay in the maritime Antarctiwhile no differences were found for high mixing situations (.. > 20 m). This suggests different photoacclimation of phytoplankton responses, induced by modifications of the light field, which in turn are controlled by physical forcing. Our results suggest that although in experimental work .*. can b

However, recent data from large species lists covering broad geographical ranges suggest strongly that there is a gradient of increasing species richness from the Arctic to the tropics. However, the Southern Ocean has high species

There appeared to be no differences in octopodid species assemblage in the two sampling areas (Kapp Norvegia and south of Drescher Inlet), supporting the theory that there is a single macrobenthic assemblage on the eastern shelf of the Weddell Se

F. Marchi,Sara Bonasia,Thomas Robertamilies studied in this work were collected on the shelf of the Eastern Weddell Sea (Antarctica) during the EASIZ-I (1996) and EASIZ-II (1998) expeditions. Among the Polynoidae, three different species of the genus . were observed to brood eggs under the dorsal elytra, which is an uncommon feature i
