Climatic variation and tree-ring structure in conifers: empirical and mechanistic models of tree-ring width, number of cells, cell size, cell-wall thickness and wood density

Abstract

Variations in tree-ring structure are simulated with: 1) an empirical model using monthly climatic data as statistical predictors, and 2) a mechanistic model using daily climatic data as growth limiting conditions. The mechanistic model has been validated for Pinus sylvestris from dry sites in S Siberia and for P. ponderosa from S Arizona. -from Authors
