First Report on the Phytochemical and Pharmacological Properties of Hedysarum yilmazunalii

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Hedysarum yilmazunalii was collected from Erzincan, Türkiye. The leaf, stem, and root parts were then used for methanolic extraction. The extracts were analyzed for their phytochemical composition by LC–MS/MS and tested for antioxidant, enzyme inhibitory, and antiproliferative activities.

Organ‐Specific Volatile Profiling of Lactuca tatarica (L.) C.A.Mey. (Asteraceae) Reveals Metabolic Differentiation by MSD–SPME–GC–MS/FID

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
MSD–SPME–GC–MS/FID reveals distinct organ‐specific volatile signatures in Lactuca tatarica. Leaves are dominated by lipid‐derived aldehydes, roots exhibit a mixed profile of aldehydes and terpenoids, and seeds are characterized by aldehydes and aromatic ketones.

Estimating Area of Occupancy From Incomplete Occurrence Records: Reproducible Workflow Illustrated on a Comprehensive Dataset of Georgian Snakes

Ecology and Evolution, Volume 16, Issue 9, September 2026.
The workflow is presented that helps to optimize grid‐cell size by breakpoint search and to estimate the area of occupancy (AOO) more precisely, if the occurrence data are incomplete. The model was validated on 13 colubrid snakes found in Georgia. The scripts in R and full statistical workflow are provided in the paper and the Supporting Information ...

Long‐Term Temporal Change of Small Mammal Composition and Abundance in the Food Intake of the Western Barn Owl (Tyto alba), Comparing Two Different Lowland Mesoregions

Ecology and Evolution, Volume 16, Issue 9, September 2026.
The object of this study is to evaluate and compare the changes of the small mammal assemblages between two lowland mesoregions in Hungary based on Western Barn Owl pellet analysis. Prey composition, diversity, and community dynamics differed markedly between the two lowland regions, indicating that local landscape characteristics and weather ...

Effects of Climatic Factors and Disturbance on Plant Above‐Ground Biomass and Species Diversity of Chinese Grasslands: A Meta‐Analysis

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This meta‐analysis across China reveals that grassland biomass is primarily driven by human disturbance and precipitation, while biodiversity is more influenced by climate. Both metrics perform better under mowing and fencing than grazing, with biodiversity and biomass generally sharing a positive linear relationship.
