The growth of two Antarctic lamellibranchs, Adamussium colbecki (E.A. Smith) and Laternula elliptica (King and Broderip), has been investigated. A. colbecki is a pectinid that grows to a shell height […]
O’HARA1 has recently proposed an open-system model for the fractional crystallisation of magmas involving continual replenishment of the magma chamber and only partial extraction of the fractionated liquid at each […]
Following current interpretation of isotope data from oceanic basalts, the case for inheritance of Rb/Sr and 87Sr/86Sr ratios in continental igneous rocks from long-lived heterogeneities in the mantle is reviewed, […]
Following a shift from autotrophic to heterotrophic nutrition, cells of Chlorella protothecoides become sensitive to the stresses of freezing and thawing. The injury then observed at slow rates of cooling […]
Motivation The molecular processes regulating molluscan shell production remain relatively uncharacterised, despite the clear evolutionary and societal importance of biomineralisation. Results Here we built the first computationally predicted gene regulatory […]
Invasive alien species are among the most significant conservation threats for Antarctica, and the South Orkney Islands are highly exposed to this threat because of their location and intensity of […]
Six main British Antarctic Survey stations were occupied throughout the year. Of these, Adelaide air base on Adelaide Island was closed down at the end of the summer, as it […]
