Wood‐Derived 3D Conductive Cellular Bio‐C@YB2C2 Ceramics for Efficient Electromagnetic Shielding and Joule Heating

open access: yesElectron, EarlyView.
Herein, a biomimetic, anisotropic, robust wood‐derived 3D conductive Bio‐C@YB2C2 framework was synthesized by in situ boron/carbon thermal reduction reaction on the carbonized wood template. The as‐obtained Bio‐C@YB2C2 composites accurately inherit the specific microstructure of natural wood, providing pathways for terahertz wave dissipation.

Wildfire Emissions From European Boreal Fuels: Effects of Fuel Type and Moisture Content

open access: yesFire and Materials, EarlyView.
ABSTRACT The increasing severity of wildfires poses significant challenges through the release of greenhouse gases and other harmful gases and particles. Although field measurements exist, there is a lack of systematic data collection to understand the influence of moisture content on the particle and gas emissions of boreal fuels, particularly for ...

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Monitoring wolverine (Gulo gulo) distribution across the western United States for regional and national assessment

open access: yesThe Journal of Wildlife Management, EarlyView.
We estimated the distribution of the federally threatened wolverine (Gulo gulo) across the western United States in 2022, evaluated changes in distribution since 2017 (the last survey), and made inference on drivers of wolverine occurrence. This monitoring program and subsequent results are used by states to make management and conservation decisions ...
