The Tropical Indo‐Pacific and North Atlantic Precursors for the Interannual Variation of Extreme Humid‐heat Days in the Yangtze River Basin

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Extreme humid‐heat events pose a major hazard across the Yangtze River Basin (YRB), yet their underlying mechanisms and seasonal predictability remain insufficiently understood. Here, using observational diagnostics and coupled model experiments, we identify three independent drivers in the tropical Indo‐Pacific and subtropical North Atlantic ...

Comparison of Seda‐Block and Xylazine–Ketamine Anaesthesia for Metacarpal and Radioulnar Osteosynthesis in Calves

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This abstract illustrates two bovine anaesthesia techniques: the brachial plexus block, which targets nerve roots at the shoulder and intravenous regional anaesthesia (IVRA), which uses a tourniquet and venous injection. Both methods provide effective distal forelimb analgesia for clinical and field surgical procedures in calves.

Balancing Aerobic and Anaerobic Metabolism, and Its Effect on Recovery Time in Freely‐Diving Steller Sea Lions (Eumetopias jubatus)

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT As breath‐hold divers, marine mammals must coordinate their use of both aerobic and anaerobic metabolism to maximize their time at depth. One indication of the relative reliance between these two energy‐producing systems is the aerobic dive limit (ADL), defined as the dive duration where post‐dive blood lactate concentrations surpass resting ...
