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

Accuracy assessment of GEDI terrain elevation, canopy height, and aboveground biomass density estimates in Japanese artificial forests

Science of Remote Sensing
Global forests face severe challenges owing to climate change, making dynamic and accurate monitoring of forest conditions critically important. Forests in Japan, covering approximately 70% of the country's land area, play a vital role yet often ...

Gamma Rays Signal the Vulnerability of Forest to Extreme Drought

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Extreme drought and heat are driving forest die‐off globally, yet regional‐scale mapping of subsurface water storage capacity, governing forest vulnerability, remains a major challenge. Here, we demonstrate that airborne gamma‐ray spectrometry (GRS) of potassium (40K) decay provides a powerful proxy for subsurface constraints on water ...

The contribution of small trees to carbon stocks along a recovery gradient in the Amazonia

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Most ecological knowledge about carbon recovery during natural regeneration in tropical regions has focused on individuals exceeding 10 cm in diameter. However, the contribution of smaller individuals to aboveground carbon (AGC) across successional gradients remains poorly quantified, despite their potentially substantial role during early ...

Evaluating and comparing the performance of ICESat-2 and GEDI data for estimating aboveground biomass in mangroves

International Journal of Digital Earth
The launch of the ICESat-2 and GEDI spaceborne LiDAR missions has provided new opportunities for large-scale estimation of mangrove aboveground biomass density (AGBD); however, their footprint-scale performance remains unclear.

Estimating the Optimal Threshold for Accuracy Assessment of the Global Ecosystem Dynamics Investigation (GEDI) Data in a Gentle Relief Urban Area

Remote Sensing, 2022
LiDAR is an excellent source of elevation data used in many surveys. The spaceborne handle system, Global Ecosystem Dynamics Investigation (GEDI), provides ground elevation information with high accuracy except for areas with steep slopes. GEDI data have

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 ...

Frailty‐associated outcomes in geriatric emergency medicine ward patients: A retrospective cohort study informing program development

Hong Kong Journal of Emergency Medicine, Volume 33, Issue 4, August 2026.
Abstract Background Frail elderly patients require more interventions, and longer hospitalizations due to their complex health needs. The Emergency Medicine Ward (EMW) aims to provide acute care for patients with low‐acuity medical issues, often using a multidisciplinary approach for holistic care and discharge.

Modelling forest volume with small area estimation of forest inventory using GEDI footprints as auxiliary information

International Journal of Applied Earth Observations and Geoinformation, 2022
The French National Forest Inventory provides detailed forest information up to large national and regional scales. Forest inventory for small areas of interest within a large population is equally important for decision making, such as for local forest ...
