Abstract BACKGROUND This study explores the development of active films incorporating ferulic acid (FA), a natural antioxidant, at concentrations of 0 (F1), 2.5 (F2), and 5 g L−1 (F3) into sodium alginate (SA; 13 g kg−1) and pectin (P; 10 g kg−1) matrix.

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.

Photooxidation of 18‐Carbon Polyunsaturated Fatty Acids to Prepare Mono‐Hydroxylated Octadecanoids
We developed a fast and simple one‐step synthetic strategy to produce mono‐hydroxylated metabolites based on the photosensitized oxidation of 18‐carbon polyunsaturated fatty acids (PUFAs). This approach could likely be extended to other PUFAs, suggesting that photosensitized oxidation could be employed to rapidly prepare hydroperoxides from multiple ...

A simple index for assessing cumulative human impacts on mountain lakes
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped
