Genomics detects population structure within and between ocean basins in a circumpolar seabird: the white‐chinned petrel
Read more of: Genomics detects population structure within and between ocean basins in a circumpolar seabird: the white‐chinned petrelThe 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 […]

Sex differences in migration and demography of a wide-ranging seabird, the northern gannet
Read more of: Sex differences in migration and demography of a wide-ranging seabird, the northern gannetMarine 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 […]

Multi-tracer study of gas trapping in an East Antarctic ice core
Read more of: Multi-tracer study of gas trapping in an East Antarctic ice coreWe 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 […]

Juvenile morphology of the large Antarctic canopy-forming brown alga, Desmarestia menziesii J. Agardh
Read more of: Juvenile morphology of the large Antarctic canopy-forming brown alga, Desmarestia menziesii J. AgardhFor 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 […]

Respiratory metabolism of Alaskozetes antarcticus
Read more of: Respiratory metabolism of Alaskozetes antarcticusMeasurements of oxygen consumption in all post-embryonic life stages of U.K. cultured Alaskozetes antarcticus (Acari: Cryptostigmata) showed that log10 respiration rate was linearly related to log10 live weight, while loge […]

Effect of temperature change on the metabolic rate of an antarctic mite
Read more of: Effect of temperature change on the metabolic rate of an antarctic miteMeasurements of metabolic rate in the terrestrial miteAlaskozetes antarcticus showed that the ability for metabolic temperature compensation is lacking in adults of this species. Animals cultured at 0 and 10°C […]

Depolarization of radio waves can distinguish between floating and grounded ice sheets
Read more of: Depolarization of radio waves can distinguish between floating and grounded ice sheetsPolar ice is now thought to be marginally birefringent at radio echo-sounding frequencies. An experiment on the polarization behaviour of 60 MHz radio echoes from the bed of both ice […]
