Elevated CO sub(2) Influences the Responses of Two Birch Species to Soil Moisture: Implications for Forest Community Structure

Anthropogenically elevated levels of atmospheric carbon dioxide may change the structure and composition of diverse plant communities via impacts on the ways in which individual species respond to their physical and biological environment. Results are presented from experiments carried out to assess...

Summary:Anthropogenically elevated levels of atmospheric carbon dioxide may change the structure and composition of diverse plant communities via impacts on the ways in which individual species respond to their physical and biological environment. Results are presented from experiments carried out to assess the ways in which elevated CO sub(2) influenced the responses of seedlings of paper birch (Betula papyrifera Marsh.) and yellow birch (Betula alleghaniensis Britt.) to changes in soil moisture. Samples of the seedlings used for these tests were raised under both ambient and elevated CO sub(2). Growth enhancement associated with elevated CO sub(2) was higher in seedlings watered less frequently than in seedlings watered sufficiently.
