Determinations of oxygen uptake of size classes I, II, III and IV of the collembolan Cryptopygus antarcticus Willem at +5°, +10° and +20°C were made at South Georgia, sub-Antarctic. The […]
This expedition to Iceland was concerned with ice depth soundings of the largest ice cap in Europe and involved both the development of impulse radar systems and the use of […]
Major and trace element analyses and strontium isotope ratios are presented for twenty-four samples of lavas and plugs from the early Tertiary lava pile in Mull. The samples were selected […]
The flow rate and ionic composition of bile during spontaneous secretion were measured in anaesthetized penguins in which the enterohepatic circulation had been interrupted and with i.v. injection of saline […]
There is growing evidence that microplastic pollution (
The Southern Ocean represents a continuous stretch of circumpolar marine habitat, but the potential physical and ecological drivers of evolutionary genetic differentiation across this vast ecosystem remain unclear. We tested […]
Marine vertebrates show a diversity of migration strategies, including sex differences. This may lead to differential demography, but the consequences of such between-sex variation are little understood. Here, we studied […]
We study a firn and ice core drilled at the new “Lock-In” site in East Antarctica, located 136 km away from Concordia station towards Durmont d’Urville. High resolution chemical and physical […]
For many types of seaweeds in Polar Regions, open questions remain about how their life cycle contributes to their overall adaptation to the extreme abiotic environment. This applies in particular […]
