Lidar‐Based Observations of Pollen Above a Mixed Hardwood Forest in the United States

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract We present lidar (LIght Detection And Ranging) and particle measurements from a mixed hardwood forest in northern Michigan over a 74‐day period in April–July 2016, capturing the peak spring tree pollen emissions season. Mini Micropulse Lidar (MPL) observations of the normalized ratio backscatter and depolarization ratios show pollen plumes ...

Chemotaxonomy and Bioactivity of Cupressus sempervirens Varieties Essential Oils: Insights Into Their Antioxidant and Enzyme Inhibitory Potential

open access: yesChemistry &Biodiversity, Volume 22, Issue 12, December 2025.
This figure summarizes the study on the chemotaxonomy and biological activities of essential oils from three Tunisian Cupressus sempervirens varieties (var. horizontalis, var. numidica, and var. pyramidalis). Essential oils were obtained by hydrodistillation and analyzed by GCMS, revealing 47 identified compounds, with α‐pinene and 3‐carene as the ...

Diversity–Elevation Relationships of Vascular Plants in Austral Temperate Ecosystems Are Strata Dependent

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We investigated diversity patterns of vascular plants of overstorey and understorey vegetation separately per stratum and the influence of anthropogenic disturbances along two elevational transects with contrasting slope aspects in a temperate rainforest and alpine scrub in southern Chile.

A Decision Support Tool Using an Open‐Source Methodology for Identifying Woody Encroachment and Juniper Species Vulnerability in the Chickasaw Nation, Oklahoma, USA

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
First American peoples have relied on cultural burning to manage their lands and sustain healthy ecosystems, but modern agricultural practices and fire suppression have led to widespread juniper tree infestation in areas like Oklahoma. In response, the Chickasaw Nation developed an open‐source methodology, model and resulting decision‐support tool to ...

Integrative Toxicology Profiling of Thuja sutchuenensis Essential Oil: From LD50 Safety Assessment to Hepatic Apoptosis and Gut Microbiota Modulation

open access: yesFood Science &Nutrition, Volume 13, Issue 12, December 2025.
This study provides the first experimental evidence of Thuja sutchuenensis essential oil (TEO) toxicity, with an oral LD50 of ~3800 mg/kg in mice. Sub‐LD50 doses cause focal hepatic necrosis via apoptosis/oxidative stress–related pathways without systemic inflammation or renal injury.
