… -structural carbon in trees in natural forests in order to estimate the potential for a carbon-…
low temperature tree limit, argue against the ‘carbon limitation’ hypothesis of treeline formation. …

… and the soil suggest that C availability is not the primary resource limitation for tree growth.
If C were limiting tree growth, it would only be through C limitation to nutrient cycling in forest …

… of the likelihood of C-limitation in trees as it can be derived from comparative analyses of
tissue C-reserve concentrations. First, I will focus on trees growing under more or less benign …

… limitation to growth We still have a poor understanding of what limits tree growth under
many conditions. In general, tree growth can be limited by the availability of carbon within the …

… We exposed saplings of 10 temperate tree species differing in shade tolerance to 6% of
ambient sunlight for 3 yr to induce C limitation, and also defoliated one species, Carpinus betulus…

… tree resource allocation priorities under reduced carbon supply. In contrast to current
understanding and model implementations, we show that trees prioritize carbon … negative carbon …

… carbon stress, trees can prioritize carbon reserve formation at the expense of growth. Our
results suggest that as carbon limitation … not be evidence that reduced tree growth under cold or …

… C pools in trees are indicators of surplus C and therefore that C is not limiting to tree growth
in the long term. We suggest that the question of whether C limits growth in trees is perhaps …

… Does C availability ever limit tree growth? One way to test whether carbon limitation plays
a role in tree growth is to expose trees 59 to elevated CO2. After a decade of CO2 fertilization …

… Historically, carbon limitation, through a shortage of photoassimilates has been argued to
limit the growth of trees at the upper altitudinal treeline. In a three-year free-air CO 2 …
