Metabolic adaptations of antarctic terrestrial micro-arthropods
Read more of: Metabolic adaptations of antarctic terrestrial micro-arthropods1. 1. Comparative analyses of standard metabolism, as measured by weight specific oxygen consumption, for Antarctic and temperate terrestrial Acari show that polar forms of the Cryptostigmata and Mesostigmata exhibit […]

Spontaneous and bile salt stimulated bile secretion in the Adelie penguin (Pygoscelis adeliae)
Read more of: Spontaneous and bile salt stimulated bile secretion in the Adelie penguin (Pygoscelis adeliae)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 […]

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 […]
