Antimycobacterial and Nitric Oxide Production Inhibitory Activities of Goyazensolide and Centratherin Isolated From Eremanthus crotonoides by High‐Speed Countercurrent Chromatography

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT In this study, bioassay‐guided fractionation of the ethanolic extract from Eremanthus crotonoides leaves enabled the isolation of two bioactive sesquiterpene lactones, centratherin and goyazensolide, which were evaluated for their antimycobacterial and anti‐inflammatory properties.

Gastroprotective Effect of Artemisia herba‐alba Leaf Extract in Acetic Acid–Induced Gastric Ulceration in Wistar Rats

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT Gastric ulcers are common gastrointestinal lesions resulting from oxidative stress and inflammation. Artemisia herba‐alba, a medicinal plant with antioxidant and anti‐inflammatory properties, was evaluated for its curative effects against acetic acid‐induced gastric ulcers in Wistar rats. The aqueous leaf extract was characterized by LC‐MS and

Mechanism of Dietary Variation of Grazing Yaks on Tibetan Plateau: The Role of Seasonal Heterogeneity of Resources

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Using DNA metabarcoding, we show that Tibetan yaks are highly selective foragers in the resource‐rich summer but switch to a diverse, generalist diet to survive the harsh winter. This flexible foraging strategy is driven by seasonal plant availability, providing strong support for optimal foraging theory and highlighting the critical need to protect ...

Unveiling the Dietary Selection of Lowland Tapirs (Tapirus terrestris) in a Tropical Rainforest

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Large terrestrial herbivores, such as lowland tapirs (Tapirus terrestris) present many dietary ecological roles in their habitat. In this article, we investigated the diet of lowland tapirs in a tropical rainforest combining different techniques such as DNA metabarcoding, fieldwork, and plant functional traits.

Floristic Diversity and Indicator Species Analysis Along Altitudinal Gradients of the Upper Indus Basin, Northern Pakistan

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Altitudinal gradients substantially influence floristic diversity and indicator species. Three vegetation communities were identified, each shaped by specific environmental variables. Mantel test shows that altitude, Ca, K, Na are key drivers of species diversity and association.
