Arachnoideum

Figure 16-A/B. Variation of low (LMP) and high (HMP) molecular weight phenolics with elevation in Pteridium caudatum (plot A) and P. arachnoideum (plot B) along elevation gradients in the northern Andes. Continuous lines are the calculated regressions for HMP only. Data from Alonso-Amelot et al., 2004)...

Figure 17. Variation of HMP contents of exposed (E) and self shaded (SS pinnae of Pteridium arachnoideum aerial parts along a 2570 - 3190 m asl transect in the northern Andes, in rainy (i ) and dry (D) times of the year. Data from Alonso-Amelot et al., 2006a.

Among the outstanding biological features, there is the extraordinary ability of bracken to colonize new territory through dispersion of enormous numbers of microscopic spores [11-13], which may amount up to 10 g per frond in the arachnoideum genotype [14]. Carried by wind, these spores travel long distances [15-16]. Bracken also takes over new land by the rapid expansion of its profuse rhizome system [17-18]. The...
