Figure 2From: Genome size expansion and the relationship between nuclear DNA content and spore size in the Asplenium monanthes fern complex (Aspleniaceae)Regression analyses of 38 specimens showing the positive relationship between DNA amount and spore length for both (A) the raw data (p = 4.57x10-6, r2 = 0.542, slope = 10.986, 95% CI’s = 8.665-13.929), and (B) data from the phylogenetically independent contrasts analysis (Branch transformation of Grafen; SMA, p = 0.101) (see Table 3). DNA amount values were logged prior to analysis, and the values used for DNA amount were based on reproductive mode: i.e. 2C-values were used for apomictic taxa, and 1C-values were used for sexually reproducing taxa. Lines of best fit are indicated using LM (black line) and SMA (red line) models, and in B only, the SMA is forced through the origin. In plot A, open circles represent apomictic taxa, and filled black circles represent sexually reproducing taxa.Back to article page
