    This file contains 5 columns (variables) x 24546 rows (excluding the first row, which contains the header with the variable names). The data were used to plot establishment and mortality dates classified by early growth and colored by lifespan (Figure 3 in Bigler 2016) and to plot plot-specific variability of early growth (S2 Fig.). The year of establishment was estimated as the formation year of the first tree ring (corrected for missed rings between pith and first tree ring on the core). The year of mortality was estimated by the formation year of the last tree ring on the core. Due to the occurrence of partial cambial mortality, the year of mortality was only approximated (see Bigler & Rigling 2013)

    Data2

    This file contains 13 columns (variables) x 160 rows (excluding the first row, which contains the header with the variable names). The data were used to create: (1) a boxplot with DBH (diameter at breast height) inside bark versus categories of early growth (Fig. 2a in Bigler 2016); (2) a boxplot with lifespan versus categories of early growth (Fig. 2b in Bigler 2016); (3) pairwise scatter plots between lifespan, early growth, DBH inside bark and topographical variables (S1 Fig. in Bigler 2016); and (4) a scatter plot between early growth and lifespan (S3 Fig. in Bigler 2016). The data were further used to estimate linear mixed-effects models for predicting lifespan of mountain pines (Tables 1 and 2 in Bigler 2016)

    <p>Description of model 32 (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0150402#pone.0150402.t001" target="_blank">Table 1</a>).</p

    Distribution of tree size and lifespan versus early growth.

    <p>Boxplots of (a) DBH<sub>ib</sub> (diameter at breast height inside bark) at the time of tree death; and (b) lifespan. The variables are plotted for different classes of early growth (mean ring width over the first 50 years; n = 160 trees).</p

    Comparison of temperature and precipitation with establishment and mortality of mountain pines.

    <p>(a) Mean temperatures (May to September) from 1780 to 2008. Shaded colors indicate values above and below the overall mean temperature (8.27Β°C); (b) precipitation sums (May to September) from 1801 to 2003. Shaded colors indicate values above and below the overall mean precipitation (550 mm); (c) line plot of crossdated increment cores. Each horizontal line extends from the year of establishment (represented by the formation year of the first tree ring, corrected for missed rings) to the approximate year of mortality (represented by the formation year of the last tree ring) of a dead mountain pine. The same number of trees and classes of early growth as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0150402#pone.0150402.g001" target="_blank">Fig 1</a> are shown. Within each class of early growth, the trees were ordered according to the year of establishment. The color gradient indicates the lifespan of the trees.</p

    Development of tree size with age.

    <p>Tree size is represented by DBH<sub>ib</sub> (diameter at breast height inside bark); the color gradient indicates the lifespan of the mountain pines. Trees were assigned to classes of early growth (mean ring width over the first 50 years): (a) > 1.5 mm yr<sup>-1</sup> (n = 7 trees); (b) 1.25–1.5 mm yr<sup>-1</sup> (n = 8 trees); (c) 1.0–1.25 mm yr<sup>-1</sup> (n = 27 trees); (d) 0.75–1.0 mm yr<sup>-1</sup> (n = 54 trees); (e) 0.5–0.75 mm yr<sup>-1</sup> (n = 46 trees); (f) <0.5 mm yr<sup>-1</sup> (n = 18 trees).</p
