SUMMARY:Life in the freezer: how do you mix biology and ice ages? - Peter 
 Convey (British Antarctic Survey)

DESCRIPTION:Even today\, terrestrial life in Antarctica is surprisingly po
 orly known in detail. It is clear that most currently ice-free ground in A
 ntarctica would have been covered and scoured by glacial advances at the L
 ast Glacial Maximum or previous maxima. However\, as new baseline survey d
 ata have become available\, in combination with modern molecular biologica
 l analysis\, it has become clear that long-term persistence and regional i
 solation is a feature of the Antarctic terrestrial biota whose generality 
 has not previously been appreciated. As well as creating a new paradigm in
  which to consider the evolution and adaptation of Antarctic terrestrial b
 iota\, this opens important new cross-disciplinary linkages in the fields 
 of understanding the geological and glaciological history of the continent
  itself\, and of the climatic and oceanographic process that can both lead
  to isolation and support colonisation processes. This new and more comple
 x understanding of Antarctic biogeography also provides important practica
 l challenges for management and conservation in the region\, as required u
 nder the Antarctic Treaty System.
