Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Functional traits explain responses of Appalachian birds to vertical and horizontal forest structure

Journal of Animal Ecology, EarlyView.
The study of bird–forest relationships dates back decades, but rarely have the relationships of functional traits to 3D forest structure responses been considered for dozens of species at regional scales. Abstract Species interact with habitat based on their functional traits, but it is unclear how specific traits interact with the multiple components ...

Asynchronous Coupling Between China's Forest Canopy Structure and Belowground Biomass Carbon in the 21st Century

Land Degradation &Development, Volume 37, Issue 14, Page 10127-10146, 30 August 2026.
ABSTRACT The spatio‐temporal relationship between Forest Canopy Structure (FCS) and Belowground Biomass Carbon (BGBC) is fundamental to determining how optimizing spatial structure can maximize forest carbon‐sink potential in land management. However, the lidar data resolution over the space and time exists limitation, causing the coupling relationship

Cook's distance-guided neural network interpolation: enhancing spaceborne LiDAR data for forest canopy height mapping

International Journal of Digital Earth
Forest canopy height (FCH) is crucial for evaluating forest structure, carbon storage, biomass, and ecosystem dynamics, which can be derived by spaceborne LiDAR systems like Ice, Cloud and land Elevation Satellite-2 (ICESat-2) and Global Ecosystem ...

Dust Layer Height Leads Atmospheric Boundary Layer Height by 3 hr Over the Taklimakan Desert

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The vertical distribution of dust modulates its radiative forcing and long‐range transport, yet the diurnal relationship between dust layer height (DLH) and atmospheric boundary layer height (ABLH) remains poorly constrained by observations.

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 ...
