Introduction The response of plants to changes in environmental conditions such as climate atmospheric CO 2 concentration or nutrient inputs is dependent on the plants ability to acclimate and adapt to the new conditions In particular there is strong evidence that plants can respond plastically to changes in nutrient limitation Bloom et al 1985 Chapin et al 1986 which in turn
