Journal of Vegetation Science, Volume 37, Issue 2, March/April 2026.Host tree identity drives bark physico‐chemical filters (e.g., pH, metals) that shape epiphytic communities. We show that species‐specific functional traits, such as lichen substances and bryophyte growth forms, mediate these responses. Lichen metal homeostasis and bryophyte growth habit create distinct species thresholds and community change points ...

The ultraviolet and infrared spectra of some lichen depsides and depsidones
, 1966 The ultraviolet and infrared spectral data for a number of lichen depsides, depsidones and their fission products have been recorded. The U.V. spectra of the orcinol depsides, orcinol depsidones and β-orcinol depsidones are characteristic while those of ...

Mass Spectrometry Reviews, Volume 45, Issue 1, Page 120-146, January/February 2026.ABSTRACT Tannins are widespread specialized plant metabolites that contribute significantly to the polyphenol content of plant‐based diets. Their effects on human and animal health vary depending on their structure, with potential benefits including antioxidative, antimicrobial, anthelmintic, and anticarcinogenic properties.

American Journal of Botany, Volume 112, Issue 11, November 2025.Abstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.
