Performance of NIR‐Based Regression Models for Hyperforin Quantification in St. John's Wort Under Temporal Validation

Journal of Chemometrics, Volume 40, Issue 6, June 2026.
ABSTRACT This study investigates the performance of near‐infrared (NIR)‐based partial least squares (PLS) regression models for quantifying hyperforin in Hypericum perforatum L., with particular emphasis on temporal validation and robustness analysis. Dried and ground Hypericum samples were analyzed using three different NIR spectrometers: one benchtop

Niche Segregation Between Black‐Necked Crane and Common Crane in Human‐Modified Landscape, Huize Black‐Necked Crane National Nature Reserve, Yunnan Province, Southwestern China

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We investigated how Black‐necked Cranes and Common Cranes coexist in agro‐wetland landscapes of southwest China by reconstructing their plant‐based diets using eDNA metabarcoding. Black‐necked Cranes maintained broad, stable diets centered on natural vegetation, while Common Cranes shifted dynamically to energy‐dense crops, leading to progressive niche

Terniopsis chanthaburiensis (Podostemaceae), a new record for China and its complete plastid genome

Nordic Journal of Botany, Volume 2026, Issue 3, March 2026.
The genus Terniopsis consists of plants that have not been thoroughly studied, with many species remaining taxonomically unresolved. In this study, Terniopsis chanthaburiensis is reported as a new record of China based on morphological traits. Then, we assembled and annotated its chloroplast genome based on genome skimming data.
