Abstract
Effects of climate on site productivity of white spruce (Picea glauca) plantations were examined. Stem analysis data collected from 93 dominant or co-dominant white spruce trees sampled from 93 plots (1 tree/plot) in even-aged monospecific plantations on 31 sites (three plots/site) in the Canadian boreal forest region of Northern Ontario were used to examine effects of climate on site productivity and to develop stand height models. Site index was used as an estimate of site productivity. Effects of site and climate on site productivity were examined by regressing site index against site and climate variables. The site specific attributes explained 33% of the variability in site index for white spruce. Stand height models were then developed by incorporating climate variables. Climatic effects specifically those of projected increased warming and rainfall on stand height growth were evaluated by predicting stand heights for three randomly selected locations (in eastern, western, and southern Ontario) for ...
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
