Predicting the response of a temperate forest ecosystem to atmospheric CO(sub 2) increase. Final report, 1984--1995

摘要

This document describes the most recent progress made in several areas of the project. Details of individual experiments in the following areas are provided: (1) the impact of soil volume on the physiological acclimation of temperate deciduous trees in elevated CO(sub 2); (2) growth under elevated CO(sub 2): the shape as well as the size of pots is important; (3) a survey of growth responses of temperate deciduous trees to elevated CO(sub 2); (4) a survey of closely related birch species; (5) the response of temperate deciduous tress to CO(sub 2) in variable light and nutrients conditions; (6) elevated CO(sub 2) differentially alters the response of birch and maple seedlings to a moisture gradient; (7) population dynamics; (8) heat shock in elevated CO(sub 2): is there a change in temperature sensitivity; (9) response of temperate deciduous trees to CO(sub 2) in variable light and nutrient conditions; (10) changes in tree community composition and their consequences to ecosystem productivity; and (11) species diversity and ecosystem response to carbon dioxide fertilization.
