Ecological Biogeography of the Terrestrial Nematodes of Victoria Land, Antarctica
The terrestrial ecosystems of Victoria Land, Antarctica are characteristically simple in terms of biological diversity and ecological functioning. Nematodes are the most commonly encountered and abundant metazoans of Victoria Land soils, yet little is known of their diversity and distribution. Herein we present a summary of the geographic distribution, habitats and ecology of the terrestrial ne...
متن کاملA re-examination of the winds of Adélie Land, Antarctica
It has been nearly a century since the Australasian Antarctic Expedition (hereafter, AAE) under the leadership of Sir Douglas Mawson first set foot on the Antarctic continent. The party arrived at what would become the base station of Cape Denison (67°S, 142.7°E; see Fig. 1) in January 1912. For the next two years, party members maintained a record of weather observations, the first extensive m...
متن کاملGrowing in Antarctica, a challenge for white adipose tissue development in Adelie penguin chicks (Pygoscelis adeliae).
Rapid growth is of crucial importance for Adélie penguin chicks reared during the short Antarctic summer. It partly depends on the rapid ontogenesis of fat stores that are virtually null at hatching but then develop considerably (x40) within a month to constitute both an isolative layer against cold and an energy store to fuel thermogenic and growth processes. The present study was aimed at ide...
متن کاملNOTES Using Kite-based Aerial Photography for Conducting Adelie Penguin Censuses in Antarctica
-Adelie Penguins (Pygoscelis adeliae) are sensitive indicators of change in Antarctic marine and terrestrial habitats, and have been intensively monitored as part of international efforts to understand the role of apex predators in the Southern Oceans. Among the key variables annually assessed by these monitoring programs are measures of population change which are typically obtained with groun...
متن کاملChronostratigraphy of the CRP-3 Drillhole, Victoria Land Basin, Antarctica
An 823 m thick glaciomarine Cenozoic section sitting unconformably on the Lower Devonian Beacon Supergroup was recovered in CRP –3. This paper reviews the chronostratigraphical constraints for the Cenozoic section. Between 3 and 480.27 mbsf 23 unconformity bounded cycles of sediment were recorded. Each unconformity is thought to represent a hiatus of uncertain duration. Four magnetozones have b...
