The effect of drought stress on the limits and costs of plasticity in floral longevity in response to pollinator decline

American Journal of Botany, Volume 113, Issue 2, February 2026.
Abstract Premise Declines in pollinator populations can reduce pollination services to plants, resulting in lower seed production. In response to these reductions, plants could increase the probability of pollinator visitation by plastically extending floral longevity.

Diet Switching and Interspecific Competition in Sympatric Steppe Ungulates Under Seasonal Resource Variability

Ecology and Evolution, Volume 16, Issue 2, February 2026.
ABSTRACT Understanding the mechanisms of competition and coexistence among sympatric species is crucial for deepening our understanding of interspecific interactions and informing the conservation of rare and endangered wildlife. In this study, we utilized DNA macro‐barcoding technology to analyze the seasonal dietary habits of Kiang (Equus kiang) and ...

Multiple Glacial Refugia and Complex Postglacial Dynamics of Primula sikkimensis (Primuaceae) in the Heterogeneous Qinghai‐Tibet Plateau

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Primula sikkimensis persisted in distinct glacial refugia within the Hengduan Mountains and eastern Himalayas during the Last Glacial Maximum. Subsequent postglacial range expansions onto the Qinghai–Tibet Plateau were accompanied by secondary contact and interspecific hybridization, collectively enhancing genetic diversity and adaptive capacity. These

New Anthracenone and Xanthenones From Tricholaena teneriffae With Antioxidant Activity: In Vitro and In Silico Studies

Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.
Three novel phenolic compounds and one known benzoxanthenone are isolated from Tricholaena teneriffae. Compounds (1–3) demonstrate potent antioxidant activity, comparable to that of vitamin C, while compound (4) exhibits negligible activity. Docking studies are employed to validate the binding of the compounds to lipoxygenase‐3, providing evidence of ...

Sulphur Analogues of Homoisoflavonoids as Potential Treatments for Neovascular Eye Diseases

ChemMedChem, Volume 21, Issue 2, January 2026.
Neovascular eye diseases are characterised by the abnormal growth of often fragile blood vessels in the eye. Treatment focuses on reducing angiogenesis as well as reducing oxidative stress induced inflammation, a key underlying cause. Synthetic sulphur analogues of naturally occurring homoisoflavonoids, synthesised in three steps, have shown promise as
