DESCRIPTION:Prof. Mark Adams\, Faculty of Agriculture\, Food and Natural R
 esources\,University of Sydney ( AU)\nFew in the northern hemisphere recog
 nize that Australia has an area larger than Switzerland covered by snow ea
 ch winter. Large areas of land >1300m asl are dominated by snowgum (E. pau
 ciflora) woodlands and grasslands (mainly Poa spp.). The gentle terrain an
 d short winters have resulted in strongly organic soils that are the most 
 carbon-rich of all Australian soils (excepting small areas of peat). In th
 is presentation I will describe our studies of soil respiration in this br
 oad sub-alpine area\, and its temperature sensitivity. I will detail new u
 nderstandings that have arisen from measurements of soil respiratory quoti
 ents (RQ)\, using a novel flow-through system. The implications of our res
 earch will be discussed in light of predictions of reduced rainfall\, incr
 eased temperature\, and reduced duration of snow cover.Few in the northern
