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 ...

Tailoring the Properties of Functional Materials With N‐Oxides
Advanced Functional Materials, Volume 36, Issue 17, 26 February 2026.The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.“Sanghuang” is a rare, edible, medicinal macrofungus. However, various macrofungi that share similar appearances, habitats, and therapeutic effects with “Sanghuang” have been erroneously used in traditional folk medicine. As of date, metabolic differences among these “Sanghuang”‐like species have been unclear, impeding their commercial utilization ...

Biodiversity in mountain soils above the treeline
Biological Reviews, Volume 100, Issue 5, Page 1877-1949, October 2025.ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...
