Mechanisms Governing Phosphorus Dynamics in the Yellow River: The Role of Damming and the Water‐Sediment Regulation Scheme

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Phosphorus is a critical nutrient for freshwater ecosystem health, yet the interactive effects of dam operation and anthropogenic pollution on water‐sediment‐phosphorus dynamics in sediment‐rich river systems remain poorly characterized. This study analyzes the spatiotemporal heterogeneity of total phosphorus (TP) concentration (TPC) and flux (

A Practical Framework for GT‐Seq Panel Optimization

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Genotyping‐in‐thousands by sequencing (GT‐seq) panels are powerful tools in ecological, evolutionary and conservation genomics, yet the optimization process critical for robust and reproducible genotyping remains poorly formalized. Here, we present an iterative workflow for GT‐seq panel optimization that emphasizes systematic refinement ...

Contrasting dynamics of leaf potential and gas exchange during progressive drought cycles and recovery in Amorpha fruticosa and Robinia pseudoacacia

Scientific Reports, 2017
Leaf gas exchange is closely associated with water relations; however, less attention has been given to this relationship over successive drought events.

Turf track surface interaction with speed and musculoskeletal injury risk in Thoroughbred racehorses

Equine Veterinary Journal, Volume 58, Issue 4, Page 925-933, July 2026.
Abstract Background Injury modelling based on changes in speed and stride characteristics of racehorses has become a primary industry focus for the Thoroughbred racing industry. However, speed and stride characteristics are strongly associated with track condition; therefore, reliable quantification of surface variables for use in future models is ...

Welfare and Physiological Consequences of Non‐Lethal Blood Sampling From the Caudal Vasculature of Atlantic Salmon (Salmo salar L.)

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a

The Inside Waters of Vancouver Island Are Critical Foraging Habitat for West Coast Transient Killer Whales

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT West Coast Transient (WCT) killer whales (Orcinus orca rectipinnus) hunt marine mammals along the west coast of North America from California to southeastern Alaska. However, little information is available on their seasonal use of nearshore areas and the relative importance of different parts of their range.

Zinc Isotopes Reveal Cross‐Border Transport of Coal Combustion Pollutants Across the Himalayas During the Summer Monsoon

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Himalayas form a major atmospheric barrier between South Asia and Tibetan Plateau, yet cross‐barrier transport of anthropogenic metals remains poorly constrained. We use moss δ66Zn along a 750–4,100 m a.s.l. south‐north transect in Motuo to trace pollution sources and transport processes. On the southern slope, trace metals (Zn, Pb, As, Ni,
