New DNA amounts (C-values) for pteridophytes
Although C-values are important biodiversity characters, data for pteridophytes remain scarce. Obermayer et al. (pp. 209-217) estimate C-values for 30 species, increasing the number by 93 % and doubling familial representation. C-values vary 450-fold from 0.16 to 72.7 pg. Superimposing data onto a robust pteridophyte phylogeny suggests possible trends in C-value evolution.
