Southern Hemisphere climate reconstructions are limited by quantity and spatial coverage of well resolved paleoclimaterecords from the last 2000 years. This was the motivation to drill an ice core at a new site in East Antarctica…
New evidence regarding the origins of the Crustacea of Antarctic lakes is reviewed. Palaeolimnological data indicates that the cladoceran Daphniopsis studeri has been present in Lake Reid, Larsemann Hills, for over 120 000 yr.
Antarctic bryophyte communities presently tolerate physiological extremes in water availability, surviving both desiccation and submergence events.
Climate change is expected to affect the high latitudes first and most severely, rendering … Antarctica one of the most significant baseline environments for the study of global … climate change. The indirect effects of climate warming…
The origins of the freshwater fauna that inhabits Antarctic lakes are poorly known. The species … present today could be relict species that have survived Quaternary glaciations on the continent, or … Holocene migrants from more temperate regions.
Once again Antarctica is under threat with the proposal by Senator Barnaby Joyce to have mining sanctioned by the Australian Government. Dr Tracey Rogers, presenter of the 2006 J D Stewart Address at the University of Sydney Faculty of Veterinary Science…
The seasonal cycle of atmospheric N2O is derived from a 10-yr observational record at Cape Grim, Tasmania (41◦S, 145◦E). After correcting for thermal and stratospheric influences…
Bryophytes (mosses and liverworts) are sensitive indicators of environmental change and with climate change expected to occur first at high latitudes, Antarctic bryophytes are ideal study systems for the detection of climate change effects.
Bryophytes are sensitive indicators of environmental change and with climate change being expected to occur first at high latitudes, Antarctic bryophytes are ideal study systems for the detection of climate change effects.
