A primer on forest structure measurement with lidar for ecologists

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Light detection and ranging (lidar) technology has fundamentally advanced the way we measure forest structure, facilitating new insights into ecological processes. Lidar for forest ecology applications is deployed on multiple types of platforms that operate from the ground, air, or space, and each has associated strengths and limitations ...

Experimental and Numerical Investigation on Ignition and Horizontal Flame Spread for Recycled Plastic Pellets

Fire and Materials, Volume 50, Issue 5, Page 499-510, August/September 2026.
ABSTRACT Fires in recycling facilities are known for producing noxious fumes, having high heat release rates (HRRs), being difficult to extinguish and causing significant devastation to business operations. This research aims to provide experimental data and numerical models from which performance‐based designs can be developed for recycling facilities.
