Phenolic and volatile compounds in Quercus humboldtii Bonpl. wood: effect of toasting with respect to oaks traditionally used in cooperage [PDF]

open access: yesJournal of the Science of Food and Agriculture, 2018
AbstractBACKGROUNDThe most frequent renewal of barrels of different origins and species is a current trend, but this demand does not match the current availability of wood. An alternative could be the use of Quercus humboldtii wood. However, there is little information about its composition.

Death caps (Amanita phalloides) frequently establish from sexual spores, but individuals can grow large and live for more than a decade in invaded forests

open access: yesNew Phytologist, Volume 242, Issue 4, Page 1753-1770, May 2024.
Summary Global change is reshaping Earth's biodiversity, but the changing distributions of nonpathogenic fungi remain largely undocumented, as do mechanisms enabling invasions. The ectomycorrhizal Amanita phalloides is native to Europe and invasive in North America.

Variable thermal plasticity of leaf functional traits in Andean tropical montane forests

open access: yesPlant, Cell &Environment, Volume 47, Issue 3, Page 731-750, March 2024.
Abstract Tropical montane forests (TMFs) are biodiversity hotspots and provide vital ecosystem services, but they are disproportionately vulnerable to climate warming. In the Andes, cold‐affiliated species from high elevations are being displaced at the hot end of their thermal distributions by warm‐affiliated species migrating upwards from lower ...
