1. Evidence of resource partitioning between fin and sei whales during the twentieth-century whaling period

   Investigating resource partitioning of marine predators is essential for understanding coexistence of sympatric species and the functional role they play in marine ecosystems. Baleen whales are a key component of […]

2. Food falls in the deep northwestern Weddell Sea

   When pelagic organisms die and fall onto the deep-sea floor they create food falls, parcels of organic enrichment that subsidize deep benthic scavenging communities. The diversity and quantities of food […]

3. Complete distribution of the genus Laevilitorina (Littorinimorpha: Littorinidae) in the Southern Hemisphere: remarks and natural history

   Littorinid snails are present in most coastal areas globally, playing a significant role in the ecology of intertidal communities. Laevilitorina is a marine gastropod genus distributed exclusively in the Southern […]

4. Microcystin production by oscillatorialean cyanobacteria isolated from cryopreserved Antarctic mats

   Twenty cyanobacterial strains of eight morphospecies isolated from deep-frozen (-15 °C) mat samples originally collected on Ross Island, in Victoria Land, and on the McMurdo Ice Shelf were screened for […]

5. Metabolic Pathway of Phenol Degradation of a Cold-Adapted Antarctic Bacteria, Arthrobacter sp.

   Phenol is an important pollutant widely discharged as a component of hydrocarbon fuels, but its degradation in cold regions is challenging due to the harsh environmental conditions. To date, there […]

6. Carbon and nutrient cycling in Antarctic landfast sea ice from winter to summer

   Seasonal cycling in carbon, alkalinity, and nutrients in landfast sea ice in Hangar Cove, Adelaide Island, West Antarctic Peninsula, were investigated during winter, spring, and summer 2014–2015. Temporal dynamics were […]

7. Seed fungal endophytes promote the establishment of invasive Poa annua in Maritime Antarctica

   Background Invasive plants may displace native species. This is the case of Poa annua, the only non-native plant species successfully established in Maritime Antarctica. Nonetheless, it is uncertain which factors […]

8. Experimental warming increases fungal alpha diversity in an oligotrophic maritime Antarctic soil

   The climate of maritime Antarctica has altered since the 1950s. However, the effects of increased temperature, precipitation and organic carbon and nitrogen availability on the fungal communities inhabiting the barren […]

9. Temperature and pH Profiling of Extracellular Amylase from Antarctic and Arctic Soil Microfungi

   While diversity studies and screening for enzyme activities are important elements of understanding fungal roles in the soil ecosystem, extracting and purifying the target enzyme from the fungal cellular system […]

10. Turbulence in the ice shelf–ocean boundary current and its sensitivity to model resolution

    The ice shelf-ocean boundary current has an important control on heat delivery to the base of an ice shelf. Climate and regional models that include a representation of ice shelf […]

11. Using a risk assessment framework to spatially and temporally spread the fishery catch limit for Antarctic krill in the west Antarctic Peninsula: A template for krill fisheries elsewhere

    The west Antarctic Peninsula is an important breeding and foraging location for marine predators that consume Antarctic Krill (Euphasia superba). It is also an important focus for the commercial fishery […]

12. Interannual variability of the 12-hour tide in the mesosphere and lower thermosphere in 15 years of meteor-radar observations over Rothera (68° S, 68° W)

    The solar tides of the mesosphere and lower thermosphere (MLT) show great variability on timescales of days to years, with significant variability at interannual timescales. However, the nature and causes […]
