In the context of ongoing climatic warming, certain landscapes could be near a tipping point where relatively small changes to their fire regimes or their postfire forest recovery dynamics could bring about extensive forest loss, with associated effects on biodiversity and carbon-cycle feedbacks to climate change. Such concerns are particularly valid in the Klamath Region of northern California...
Metabolites in plants are essential for defence and communication with the environment. Terpenes constitute the major part of the resin in conifers. The composition of terpenes as well as of volatile terpenes changes with tissue, age, and in response to various types of stress, for example insect or pathogen attacks (Persson et al., 1993; Fäldt et al., 2006) and UV-B exposure (Zavala and Ravett...
Recent large-scale studies of tree growth in the Iberian Peninsula reported contrasting positive and negative effects of temperature in Mediterranean angiosperms and conifers. Here we review the different hypotheses that may explain these trends and propose that the observed contrasting responses of tree growth to temperature in this region could be associated with a continuum of trait differen...
Recent molecular phylogenetic studies indicate, surprisingly, that Gnetales are related to conifers, or even derived from them, and that no other extant seed plants are closely related to angiosperms. Are these results believable? Is this a clash between molecules and morphology?
