1. Male reproductive strategy and the importance of maternal status in the Antarctic fur seal Arctocephalus gazella

   Although mammalian mating systems are classically characterized in terms of male competition and polygyny, it is becoming increasingly apparent that alternative male strategies and female choice may play important roles. […]

2. Colonization, succession, and extinction of marine floras during a glacial cycle: a case study from the Windmill Islands (east Antarctica) using biomarkers

   With the exception of the diatoms, little is known of the extinction, colonization, and succession of marine floras during glacial cycles. Here we study both morphological and biochemical fossils in […]

3. Scaling in long term data sets of geomagnetic indices and solar wind epsilon as seen by WIND spacecraft

   We study scaling in fluctuations of the geomagnetic indices (AE, AU, and AL) that provide a measure of magnetospheric activity and of the ϵ parameter which is a measure of […]

4. A synthesis of growth rates in marine epipelagic invertebrate zooplankton

   We present the most extensive study to date of globally compiled and analysed weight-specific growth rates in marine epi-pelagic invertebrate metazoan zooplankton. Using specified selection criteria, we analyse growth rates […]

5. Growth of marine planktonic copepods: global rates and patterns in relation to chlorophyll a, temperature, and body weight

   We compiled a global data set of copepod in situ weight-specific fecundity and growth rates, together with measurements of their body weights, and the chlorophyll a and temperature of the […]

6. Thermomechanical coupling of ice flow with the bedrock

   Two aspects of thermal coupling with bedrock are considered: the coupled time-dependent problem of co-evolving temperatures in lithosphere and ice; and the influence of basal topography on steady temperature distribution […]

7. Temperature preferences of the mite, Alaskozetes antarcticus, and the collembolan, Cryptopygus antarcticus from the maritime Antarctic

   The thermal preferences of Alaskozetes antarcticus (Acari, Cryptostigmata) and Cryptopygus antarcticus (Collembola, Isotomidae) were investigated over 6 h within a temperature gradient (−3 to +13 °C), under 100% relative humidity […]

8. Resolving mantle components in oceanic lavas from segment E2 of the East Scotia back-arc ridge, South Sandwich Islands

   The East Scotia Ridge, situated in the South Atlantic, is the back-arc spreading centre to the intra-oceanic South Sandwich arc. Samples from the ridge show a wide diversity in erupted […]

9. Predatory behaviour and metabolic costs in the Antarctic muricid gastropod Trophon longstaffi

   Aquarium-based observations of the feeding behaviour of the Antarctic muricid gastropod Trophon longstaffi over a 3-year period revealed that individuals were capable of feeding on both bivalve (Laternula elliptica and […]

11. Observational verification of predicted increase in bedrock-to-surface amplitude transfer during a glacier surge

    The amplitude ratio between surface and bedrock topography has been predicted to depend strongly on the ratio of deformational velocity to mean basal sliding velocity. Observations made prior to and […]

12. Transmission of basal variability to a glacier surface

    Transmission of basal variability to a glacier surface is investigated using analytical models for a linearly viscous medium. The three-dimensional transient response of the surface to both bedrock undulations and […]
