Characterization of the Volatile Compounds of the Hardwood Portion of Betula papyrifera Marshall From Quebec, Canada

Chemistry &Biodiversity, Volume 22, Issue 11, November 2025.
The volatile profile of Betula papyrifera hardwood has been characterized using both hydrodistillation and HS‐SPME coupled with GC‐MS/FID. Hydrodistillation yields a fatty acid‐rich essential oil, while HS‐SPME reveals a broader range of low‐molecular‐weight volatiles, including aromatics and terpenoids.

The Role of Rock Fractures as a Water Source for Trees Growing in Karst

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract Global warming has led to accelerated transitions between dry and wet periods, causing plants to experience more water stress and adapt water use strategies. This could have a significant impact on plants in karst regions due to the substantial spatial and temporal variability of soil and rock moisture. In this study, we monitored and compared
