Are treelines responding to climate change?

If you have a question about this talk, please contact jb511.

Will climatic warming allow the Boreal forest to advance onto the treeless Tundra? Will trees at the low temperature limits of their distribution respond differently if they are deciduous or evergreen? Will trees 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 genetic differences as these properties are not constant in relation to any one simple climatic parameter. Changes in seasonal temperatures alone may create barriers to distribution not previously experienced.
