1. Life hung by a thread: endurance of Antarctic fauna in glacial periods

   Today, Antarctica exhibits some of the harshest environmental conditions for life on Earth. During the last glacial period, Antarctic terrestrial and marine life was challenged by even more extreme environmental […]

2. External parasite infestation depends on moult-frequency and age in Antarctic krill (Euphausia superba)

   Levels of infestation by the suctorian Ephelota sp. were determined in Antarctic krill taken in the north-eastern region of the Scotia sea, close to the island of South Georgia. Individuals […]

3. Post-breeding movement and activities of two streaked shearwaters in the north-western Pacific

   We used miniature light-level/immersion loggers (geolocators) to study the movements and behavior of two Streaked Shearwaters (Calonectris leucomelas) during their travel away from Japan, after the breeding season. During the […]

4. Trophic modes of large Antarctic Foraminifera: roles of carnivory, omnivory, and detritivory

   Astrammina rara, Crithionina delacai, and Notodendrodes hyalinosphaira are 3 of the largest and most abundant members of the foraminiferal assemblage at a shallow-water (28 to 32 m) site in Explorers […]

5. Ontogenetic shifts in the trophic ecology of two alvinocaridid shrimp species at hydrothermal vents on the Mariana Arc, western Pacific Ocean

   The Mariana Arc of submarine volcanoes has recently been the site of an international, interdisciplinary study into the structure and function of the associated hydrothermal systems. A broad size range […]

6. Six million years of glacial history recorded in volcanic lithofacies of the James Ross Island Volcanic Group, Antarctic Peninsula

   Basaltic volcanism in the James Ross Island region has been persistent over the last 6 million years resulting in at least 50 mainly effusive eruptions that are preserved predominantly as […]

7. Basaltic subglacial sheet-like sequences: evidence for two types with different implications for the inferred thickness of associated ice

   Subglacially-erupted volcanic sequences provide proxies for a unique range of palaeo-ice parameters and they are potentially highly useful archives of palaeoenvironmental information, particularly for pre-Quaternary periods. They can thus be […]

8. Spatial variability in the distribution of dominant shallow-water benthos at Adelaide Island, Antarctica

   Studies from temperate and tropical regions have shown that variability in the distribution of benthos exists at different spatial scales. There are very few similar studies from polar systems, the […]

9. Likely responses of the Antarctic benthos to climate-related changes in physical disturbance during the 21st century, based primarily on evidence from the West Antarctic Peninsula region

   Disturbance has always shaped the evolution and ecology of organisms and nowhere is this more apparent that on the iceberg gouged continental shelves of the Antarctic Peninsula (AP). The vast […]

11. Ecological traits of benthic assemblages in shallow Antarctic waters: does ice scour disturbance select for small, mobile, secondary consumers with high dispersal potential?

    Benthic communities in nearshore habitats around Antarctica are strongly influenced by ice disturbance. It has been suggested that where ice scour disturbance is severe, the relative importance of certain ecological […]

12. Continuous benthic community change along a depth gradient in Antarctic shallows: evidence of patchiness but not zonation

    Many shallow water polar communities demonstrate considerable change along a bathymetric gradient. However, it is currently unclear whether community change is generally continuous or discrete. To determine the nature of […]
