Investigations of Antarctic krill (Euphausia superba) over the last 40 years have examined almost every aspect of the biology of these ecologically … important animals.Various elements of krill biology have been brought together to provide concepts of how this species interacts with its environment…
Antarctica is both the coldest and most arid continent on Earth, and experiences continuous light in midsummer and continuous darkness in midwinter. These factors reduce the growth rate of the continental Antarctic flora (mosses, lichens and algae) to a minimum.
Aim: There is no previous direct evidence for the occurrence of lacustrine refuges … for invertebrate fauna in Antarctica spanning the Last Glacial Maximum (LGM).
Abstract. The discovery of an abundance of microorganisms that flourish in a diverse range of environments, from the frigid waters of the Antarctic, to the superheated waters of the hydrothermal vents, at the bottom of 11-km … deep ocean trenches and in salt-saturated lakes…
In Australia more than 300 vertebrates, including 43 insectivorous bat species, depend on hollows in … habitat trees for shelter, with many species using a network of multiple trees as roosts. We used roost-switching … data on white-striped freetail bats (Tadarida australis; Microchiroptera:
The current shape and rate of change of the margins of the Antarctic ice sheet are … poorly known. Since polar regions are inhospitable, remotely sensed images … provide an invaluable data source for studying the ice margin.
Mark-recapture models applied to double-observer distance sampling data neglect the information … on relative detectability of objects contained in the distribution of observed distances.
Thorium-234 is increasingly used as a tracer of ocean particle flux, primarily as a means to estimate particulate organic carbon … export from the surface ocean. This requires determination of both the 234Th activity distribution (in order to calculate 234Th fluxes)…
