Bark thickness and fire regime
1. Bark is a vital and very visible part of woody plants, yet only recently has bark characteristics started to be considered as key traits structuring communities and biomes. Bark thickness is very variable among woody plants, and I hypothesize that fire is a key factor selecting for a thick bark, and thus, at the global scale, a significant proportion of the variability in bark thickness is e...
متن کاملPhylogeny Predicts the Quantity of Antimalarial Alkaloids within the Iconic Yellow Cinchona Bark (Rubiaceae: Cinchona calisaya)
Considerable inter- and intraspecific variation with respect to the quantity and composition of plant natural products exists. The processes that drive this variation remain largely unknown. Understanding which factors determine chemical diversity has the potential to shed light on plant defenses against herbivores and diseases and accelerate drug discovery. For centuries, Cinchona alkaloids we...
متن کاملEvaluating Cinchona bark and quinine for treating and preventing malaria.
Whereas the efficacy of Cinchona bark and quinine for treating intermittent fevers had become widely accepted by the turn of the 18th and 19th centuries, their role in preventing fevers had not been convincingly established. However, as early as 1711, Vallot et al. had reported in the Journal de la santé du roi Louis XIV that he had learned from experience that long term administration of Cinch...
متن کاملBark thickness and fire regime: another twist.
Bark is the outermost covering of stems in woody plants and plays a fundamental protective role. Recently I hypothesized that ‘at the global scale, a significant proportion of the variability in bark thickness is explained by the variability in fire regimes’, and specifically predicted that frequent low intensity fires select for thick bark (Pausas, 2015). In addition, I suggested that differen...
متن کاملconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
