Molecular evidence for further overlooked species within the Gammarus fossarum complex (Crustacea: Amphipoda)
The freshwater amphipod Gammarus fossarum Koch, in Panzer, 1836 is a locally abundant keystone species mainly occuring in European headwaters but also in larger rivers. Genetic studies in the past 25Expand

Morphological and genetic data clarify the taxonomic status of Colossendeis robusta and C. glacialis (Pycno- gonida) and reveal overlooked diversity
Colossendeis robusta Hoek, 1881, originally described from the Kerguelen shelf, is considered as one of the most widespread Antarctic pycnogonids. However, the taxonomic status of this and similarExpand

Different feeding strategies in Antarctic scavenging amphipods and their implications for colonisation success in times of retreating glaciers
BackgroundScavenger guilds are composed of a variety of species, co-existing in the same habitat and sharing the same niche in the food web. Niche partitioning among them can manifest in differentExpand

The infauna of three widely distributed sponge species (Hexactinellida and Demospongiae) from the deep Ekström Shelf in the Weddell Sea, Antarctica
Abstract Due to their high abundance and large body size sponges have a central position in Antarctic zoobenthos, where they form the most extensive sponge grounds of the world. Though research onExpand

Fishing for scavengers: an integrated study to amphipod (Crustacea: Lysianassoidea) diversity of Potter Cove (South Shetland Islands, Antarctica)
Amphipoda from the superfamily Lysianassoidea Dana, 1849 play an important role in Southern Ocean benthic food webs due to their high biomass, abundance and predominantly scavenging mode of feeding.Expand

The importance of macroalgae and associated amphipods in the selective benthic feeding of sister rockcod species Notothenia rossii and N. coriiceps (Nototheniidae) in West Antarctica
Studies on feeding selectivity in Antarctic fish with comparison between diet organisms and those available in the wild are scarce. We explored this issue in Notothenia rossii (NOR) and N. coriicepsExpand
