2. Depth gradients in shell morphology correlate with thermal limits for activity and ice disturbance in Antarctic limpets

   To fully understand how species distributions will respond to changing environments it is essential to understand the mechanisms underlying variation in animal performance and the relative importance of different ecological […]

3. Optimal stroke frequency during diving activity in seabirds

   Diving animals have to counter both drag and buoyancy when moving through the water column. The magnitude of these forces depends upon an animal’s swim speed and current depth. Feet, […]

4. EPICA Dome C record of glacial and interglacial intensities

   Climate models show strong links between Antarctic and global temperature both in future and in glacial climate simulations. Past Antarctic temperatures can be estimated from measurements of water stable isotopes […]

5. Free as a bird? Activity patterns of albatrosses during the nonbreeding period

   This is the first comprehensive study of at-sea activity patterns of albatrosses during the nonbreeding period, based on data from combination geolocator–immersion loggers deployed on the wandering albatross Diomedea exulans, […]

6. Echiniscus corrugicaudatus (Heterotardigrada; Echiniscidae) a new species from Ellsworth Land, Antarctica

   Echiniscus corrugicaudatus sp. nov., (Heterotardigrada; Echiniscidae) was found in the limited vegetation from the inland nunataks of Ellsworth Land, West Antarctica. The tardigrade fauna of this a rarely explored region […]

7. Contrasting phylogeographical patterns for springtails reflect different evolutionary histories between the Antarctic Peninsula and continental Antarctica

   We examined the genetic structure among populations and regions for the springtails Cryptopygus antarcticus antarcticus and Gomphiocephalus hodgsoni (Collembola) to identify potential historical refugia and subsequent colonization routes, and to […]

8. Metabolic rate, genetic and microclimate variation among springtail populations from sub-Antarctic Marion Island

   Measurement of metabolic rates (made at 10A degrees C) of individuals of the springtail Cryptopygus antarcticus travei from six geographically distinct populations on sub-Antarctic Marion Island were combined with mitochondrial […]

9. Eretmoptera murphyi: pre-adapted to survive a colder climate

   During the late 1960s, larvae of the flightless midge Eretmoptera murphyi Schaeffer were accidentally transferred from the sub-Antarctic island of South Georgia to Signy Island in the maritime Antarctic. Higher […]

10. Foraging behaviour of King Penguins (Aptenodytes patagonicus) in relation to predictable mesoscale oceanographic features in the Polar Front Zone to the north of South Georgia

    Marine predators are thought to utilise oceanic features adjusting their foraging strategy in a scale-dependent manner. Thus, they are thought to dynamically alter their foraging behaviour in response to environmental […]

11. Ultrastructure of pedal muscle as a function of temperature in nacellid limpets

    Temperature and mitochondrial plasticity are well studied in fishes, but little is known about this relationship in invertebrates. The effects of habitat temperature on mitochondrial ultrastructure were examined in three […]

12. Growth and mass wasting of volcanic centers in the northern South Sandwich arc, South Atlantic, revealed by new multibeam mapping

    New multibeam (swath) bathymetric sonar data acquired using an EM120 system on the RRS James Clark Ross, supplemented by sub-bottom profiling, reveals the underwater morphology of a not, vert, similar […]
