From the Introduction (p.104) ... 'The focus of this introduction to Section II is on describing the boreal forest ecosystem in terms of those factors and processes controlling carbon cycling. Such a systems approach is not new, and similar approaches have been used to study carbon dynamics in the boreal forest (Kurz et al. 1991; Kurz and Apps 1993); however, much research is still needed to develop an integrated model of carbon cycling in the boreal forest. The intent of this introduction is not to discuss the factors and processes controlling carbon cycling in the boreal forest in depth, as these details are presented in the remaining chapters of this section and elsewhere (see, e.g., Bonan and Shugart 1989; Kasischke et al. 1995).' © 2000 Springer-Verlag New York, Inc.
