Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Increased cardiac myosin super-relaxation as an energy saving mechanism in hibernating grizzly bears

Molecular Metabolism
Aim: The aim of the present study was to define whether cardiac myosin contributes to energy conservation in the heart of hibernating mammals. Methods: Thin cardiac strips were isolated from the left ventricles of active and hibernating grizzly bears ...

Use of isotopic sulfur to determine whitebark pine consumption by Yellowstone bears: A reassessment

Wildlife Society Bulletin, 2014
Use of naturally occurring stable isotopes to estimate assimilated diet of bears is one of the single greatest breakthroughs in nutritional ecology during the past 20 years. Previous research in the Greater Yellowstone Ecosystem (GYE), USA, established a

Bacterial populations and metabolites in the feces of free roaming and captive grizzly bears

, 2009
Gut physiology, host phylogeny, and diet determine the composition of the intestinal microbiota. Grizzly bears (Ursus arctos horribilis) belong to the Order Carnivora, yet feed on an omnivorous diet.

Grizzly bear diet shifting on reclaimed mines

Global Ecology and Conservation, 2015
Industrial developments and reclamation change habitat, possibly altering large carnivore food base. We monitored the diet of a low-density population of grizzly bears occupying a landscape with open-pit coal mines in Canada.
