SUMMARY:Are treelines responding to climate change? - Professor Emeritus R

DESCRIPTION:Will climatic warming allow the Boreal forest to advance onto 
 the treeless Tundra? Will trees at the low temperature limits of their dis
 tribution respond differently if they are deciduous or evergreen?\nWill tr
 ees migrate in response to changes in winter or summer temperatures? These
  questions cannot be answered with simple generalizations. Treelines  will
  be examined for their geographical\, historical\, physiological and genet
 ic differences as these properties are not constant in relation to any one
  simple climatic parameter. Changes in seasonal temperatures alone may cre
 ate barriers to distribution not previously experienced. \n\nhttp://biolog
