We review aspects of climate change likely to impact upon the Collembola and mites (microarthropods) of Victoria Land and the Queen Maud Mountains (VLQMM) in the Ross Sea Region of Antarctica. Five important aspects of biological and biological…
We compiled and reviewed 248 cases of reported vessel collisions with small cetaceans worldwide and with large … cetaceans in the Southern Hemisphere. Difficulties were encountered with the comparison of highly variable data in … terms of quality (evidence), sources…
From a synthesis of recent oceanic observations and paleo-data it is evident that certain species … of giant diatoms including Rhizosolenia spp. Thalassiothrix spp. and Ethmodiscus rex may … become concentrated at oceanic frontal zones and subsequently form episodes of mass flux to the … sediment.
The Lambert Glacier region of East Antarctica encompasses the proposed boundary between three of the ancient continents that … formed East Gondwana: Indo-Antarctica, the central East Antarctic Craton and a proposed extension of the Pinjarra Orogen of … Australia.
The coupled ocean–atmosphere–ice response to variations in the Southern Annular Mode (SAM) is … examined in the National Center for Atmospheric Research (NCAR) Community Coupled Climate Model … (version 2).
Studies of atmospheric composition in the Southern Ocean and Antarctic region continue to … reveal new findings which have a wide relevance. This presentation will show and interpret … records of the major greenhouse and related trace species from a network of measurement … sites across the region…
New measurements of atmospheric greenhouse gas … concentrations in ice from Law Dome, Antarctica reproduce … published Law Dome CO2 and CH4 records, extend them … back to 2000 years BP, and include N2O. They have very … high air age resolution, data density and measurement … precision.
A barotropic tidal model has been applied to the Amery Ice Shelf cavity and Prydz … Bay region of East Antarctica. The sensitivity of the tidal solution of the model to … variation of the water column thickness of the Amery Ice Shelf cavity has been … determined.
Antarctic terrestrial ecosystems are noted for their relative simplicity and limited trophic structure. In this context, knowledge of biotic … interactions in structuring terrestrial soil communities would seem beneficial from a theoretical perspective as well as from a conservation … perspective.
We carried out a comparative study using mtDNA (COI) for two free-living, endemic, terrestrial invertebrate taxa—the springtail Gomphiocephalus hodgsoni (Hypogastruridae) and the mite Stereotydeus mollis (Penthalodidae) collected from sites throughout Victoria Land and the Queen Maud Mountains…
Abstract Isotoma klovstadi Carpenter, 1902 was one of … the first Collembola described from the Antarctic continent. It was first collected in November 1899 during the … British Antarctic Expedition on the north coast of Victoria … Land in the Ross Sea region.
Throughout the Southern Hemisphere many terrestrial taxa have circum-Antarctic distributions. This pattern is generally … attributed to ongoing dispersal (by wind, water, or migrating birds) or relict Gondwanan distributions. Few of these … terrestrial taxa have extant representatives in Antarctica…
Human-induced changes to natural systems can cause major disturbances to fundamental … ecological and population processes and result in local extinctions and secondary contacts … between formerly isolated species. Extensive fur seal harvesting during the nineteenth … century on Macquarie Island…
We describe the circulation and seasonal development of the upper ocean … in the Seasonal Ice Zone (SIZ) of the Southern Ocean along 140°E. The 140°E section … was repeated four times between November 2001 and March 2002, spanning the period … from early spring to autumn.
Salinity and lowtemperature effects on adsorption of contaminant metals from … water using an iminodiacetic acid (IDA) ion-exchange resin, were investigated under … dynamic flow conditions. The order of selectivity of the resin (20°C and 0% seawater) was: Cu2+Pb2+Cr3+ Ni2+Cd2+Zn2+ Low temperature…
I on exchange characteristics of Cu2þ on the natural zeolite clinoptilolite at 2 and 228C are … presented to facilitate the development of a permeable reactive barrier (PRB) to treat … heavy-metal contaminated waters in Antarctica.
