, which would lead to an overestimation of growth of younger trees, since the older fast growing trees are lost to a large degree from a contemporary sample. Narrow rings in smaller trees in comparison to larger trees in our study sites might be due to 1) smaller and presumably younger ...
Figure 1:Distribution and sample of plant data from the Tree of Sex Database. Tree structure is derived from taxonomy, where each tip represents all species in a single genus. Diploid chromosome number is indicated by the height of the innermost ring; all other rings indicate the presence or...
