Two opposing hypotheses have been presented to explain reduced tree growth at the treeline, compared with growth in lower elevation or lower latitude forests: the carbon source and sink limitation hypotheses. The former states that treeline trees have an unfavorable carbon balance and cannot support

We studied seasonal dynamics of carbohydrate storage in red spruce (Picea rubens Sarg.) seedlings by measuring starch and sugar concentrations of old needles (>/= one year old), new needles (< one year old), stems, and roots in two stands in the Green Mountains of Vermont. Although the two stands

Environmental factors that drive carbon storage are often used as an explanation for alpine treeline formation. However, different tree species respond differently to environmental changes, which challenges our understanding of treeline formation and shifts. Therefore, we selected Picea

The question of whether lignin is covalently linked to carbohydrates in native wood, forming what is referred to as lignin carbohydrate complexes (LCC), still lacks unequivocal proofs. This is mainly due to the need of isolating lignin from woody materials prior to analysis, at conditions leading to
