The combined effects of light, soil fertility, and ontogenetic changes on plant growth rates are poorly understood, yet these three factors play fundamental roles in structuring plant communities. We sought to determine how lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia), interior spruce (Picea glauca × engelmanii (Moench) Voss), and subalpine fir (Abies lasiocarpa (Hook.) Nutt.) sapling growth responds to the combination of light, soil fertility, and ontogeny and how these three dominant conifer species in sub-boreal forests of British Columbia differ in their responses. Using maximum likelihood methods, we found that 0.20–4 m tall sapling growth rates changed during ontogeny and were limited by both light and soil resources. The strongest differences among species’ growth rates were due to tree size, with smaller differences due to soil fertility, and there were no differences among species in the shape of their growth responses to light. Rank order in growth rates for small saplings (pine > spruce > fir) inversely corresponded to classic shade-tolerance ratings, thus supporting the carbon balance theory. Interior spruce height growth rates increased relative to lodgepole pine with increasing soil fertility, clearly matching the landscape-scale increase in canopy dominance of interior spruce over lodgepole pine with increasing soil fertility.

The morphological diversity of life has captivated systematists in the construction of classifications, embryologists in the study of development, and evolutionists in the formulation of theories of organic change. In a century marked by the advances of molecular biology, has the discipline of morphology produced anything … new? Yes. The solidification of paleontology and systematics and the emergence of macroevolution as a legitimate field owe much to an increased rigor in the analysis of morphological data. At the same time, the discipline of morphology has achieved an unprecedented sophistication through another development, the very expression of its maturity: theoretical morphology. Theoretical morphology forms the subject of McGhee's landmark book, an elegant combination of compendium and manifesto. Its richness and scope provide an opportunity for a critical appraisal of the discipline of morphology, particularly quantitative and developmental morphology.
