The Antarctic has experienced major changes in temperature, wind speed and stratospheric ozone levels during the last 50 years. However until recently continental Antarctica appeared to be little impacted by climate warming, thus biological changes were predicted to be relatively slow.
Persistent organic pollutants (POPs) are well known to accumulate in polar food webs; yet there is little ecotoxicological data available for environmental risk assessment of POPs in these extreme ecosystems. The premise of the tissue residue approach (TRA)…
A series of fuel spills (diesels and lubricating oils) have occurred on Macquarie Island associated with fuel storage and power generation for the Island’s research station. The Australian Antarctic Division is currently remediating these sites.
Zooplankton species are an important component of the Antarctic coastal ecosystem. The strongly seasonal sea ice cover and phytoplankton availability has driven a modification in the life cycles of many Antarctic zooplankton species. In general only one cycle is completed each year.
Manipulative field studies are useful for investigating cause–effect relationships between contamination and benthic community health. However…
This study presents the first examination of the effect of both temperature and salinity on fertilisation and development in an Antarctic echinoderm. Previous studies on Antarctic species have not investigated the combined effects of temperature and salinity, focusing on only single factor studies…
The Southern Ocean is vitally important in understanding climate change, both regionally and globally, due to factors such as the presence of the Antarctic Circumpolar Current, seasonal sea-ice and strong Southern Hemisphere westerly winds. Also, the upper branch of the Circumpolar Deep Water (UCDW)…
