Combination of Sanger and target-enrichment markers supports revised generic delimitation in the problematic ‘Urera clade’ of the nettle family (Urticaceae)

, 2020
Urera Gaudich, s.l.. is a pantropical genus comprising c. 35 species of trees, shrubs, and vines. It has a long history of taxonomic uncertainty, and is repeatedly recovered as polyphyletic within a poorly resolved complex of genera in the Urticeae tribe

Disturbance‐Associated Plant Communities in Africa's Largest Alpine Ecosystem: Evidence for Long‐Term Anthropogenic Influence

Applied Vegetation Science, Volume 29, Issue 4, October/December 2026.
This study provides the first integrated evidence of long‐term human impacts in Ethiopia's Bale Mountains, combining modern vegetation transects with sedimentary steroid and bile acid biomarkers. We identified a sharp 200 m settlement edge and reveal sustained anthropogenic influence from the late Pleistocene, with pastoralism intensifying around 6.5 ...

Diel net CO2 exchange of carnivorous Pinguicula is consistent with low‐level CAM photosynthesis

Plant Biology, Volume 28, Issue 6, Page 1813-1819, October 2026.
In carnivorous butterworts (Pinguicula), CO2 uptake occurs primarily in the light via C3 photosynthesis, yet low‐level CAM photosynthesis, including net CO2 dark fixation, significantly improves the carbon balance of plants, especially under water‐deficit conditions.

Quantitative Structure–Activity Relationship Approaches for Exploring the Anticancer Potential of Flavonoids

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
QSAR‐based analysis of flavonoids to identify structural determinants of anticancer activity and prioritize promising candidates. ABSTRACT Flavonoids are structurally diverse polyphenolic compounds widely distributed in fruits, vegetables, grains, and beverages, with considerable potential as anticancer agents.
