Abstract Background Oak barrels are widely used in wine and spirit aging, where oxygen transmission plays a key role in the development of chemical and sensory properties. In cooperage, stave selection is traditionally based on grain width; however, the extent to which grain and wood macrostructure determine oxygen transmission under barrel conditions ...

Behavioral responses of black bears to human presence and infrastructure in Yosemite National Park
Using GPS collar data from black bears in Yosemite National Park, we examined how bear spatiotemporal activity in relation to human development shifted during the COVID‐19 park closure in 2020. In the absence of visitors, bears maintained consistent landscape‐scale space use but altered fine‐scale spatial and temporal behaviors.
