1. Snow chemistry across Antarctica

   An updated compilation of published and new data of major-ion (Ca, Cl, K, Mg, Na, NO3, SO4) and methylsulfonate (MS) concentrations in snow from 520 Antarctic sites is provided by […]

2. Combined morphological and molecular analysis of individual nematodes through short-term preservation in formalin

   Small metazoans such as marine nematodes are increasingly identified using both molecular and morphological techniques. Formalin is the preferred fixative for morphological analysis but specimens become unsuitable for molecular study […]

3. Quantitative characterization of shallow marine benthic assemblages at Ryder Bay, Adelaide Island, Antarctica

   Non-destructive photographic techniques are valuable for surveying benthic epifauna in sensitive areas. Inherent in these techniques, however, are selectivity biases related to the scale at which surveys are conducted. Such […]

4. Seasonality of recruitment in Antarctic sessile marine benthos

   Recruitment is a principal factor determining the establishment, diversity and persistence of assemblages in marine benthic ecosystems. Despite considerable research in temperate and tropical latitudes, however, almost nothing is known […]

5. A new species of Paecilomyces isolated from the Antarctic springtail Cryptopygus antarcticus

   A monophialidic species of Paecilomyces was isolated from the Antarctic springtail Cryptopygus antarcticus in the peninsular Antarctic. The fungus emerged through the carapace of dead arthropods during incubation at 4oC, […]

6. The impact of molecular data in fungal systematics

   Molecular data has been used in fungal systematics since the 1970s, and its rate of incorporation has increased significantly in recent years. In phylogeny molecular data has already been used […]

7. Omnivory and predation impact of the calanoid copepod Boeckella poppei in a maritime Antarctic lake

   The copepod Boeckella poppei is a major species in high latitude lakes of the Southern Hemisphere. In such lakes the reduced diversity of metazoans contrasts with a rich microbial assemblage, […]

8. Origin, sequence stratigraphy and depositional environment of an upper Ordovician (Hirnantian) deglacial black shale, Jordan

   The upper Ordovician succession of Jordan was located ~60°S, less than 100 km from the Hirnantian ice sheet margin. New graptolite dates indicate glaciation ended in Jordan in the late […]

9. Invertebrate muscle performance at high latitude: swimming activity in the Antarctic scallop, Adamussium colbecki

   The escape swimming performance of the Antarctic scallop, Adamussium colbecki, was measured in animals acclimated for 6 weeks to –1, 0 or 2°C and tested at –1.5 to +1.5°C. Clap […]

10. Body and resource size at the land–sea interface

    Body size in animals varies with many parameters, amongst them taxonomic affiliation, lifestyle and ambient environment oxygen levels. Size has considerable implication to possibilities for animals; for example, parasites need […]

11. Changing chain: past, present and future of the Scotia Arc’s and Antarctica’s shallow benthic communities

    The Scotia Arc links Patagonia to the Antarctic Peninsula. This island chain has changed considerably since Antarctica’s geographic and thermal isolation from other land and water masses. Now its rates […]

12. Genetic structure and history of populations of the deep-sea fish Helicolenus dactylopterus (Delaroche, 1809) inferred from mtDNA sequence analysis

    Helicolenus dactylopterus is an Atlantic benthopelagic fish species inhabiting high-energy habitats on continental slopes, seamounts and islands. Partial sequences of the mitochondrial control region (D-loop) and cytochrome b (cyt b) […]
