DescriptionGlobal climate change models predict decreased rainfall in association with elevated CO2 in the western Lakes States region. Currently, the western edge of northern red oak (Quercus rubra L.) distribution coincides with the most xeric conditions of its ecological range. Decreased rainfall and water availability could alter ecological fitness and distribution. To better understand how climate change may affect this species, we are examining the interaction of CO2 (400, 520, 700 ppm CO2) with water stress (well-watered and water-stressed) on growth, and carbon and nitrogen metabolism of northern red oak seedlings through three flushes of development. In this report, we focus on growth, photosynthetic rate, and nitrogen responses to these stresses in three-flush seedlings.
