Retrieval and validation of vertical LAI profile derived from airborne and spaceborne LiDAR data at a deciduous needleleaf forest site

GIScience & Remote Sensing, 2023
Leaf area index (LAI) is defined as one half of the total green leaf area per unit ground surface area. Its vertical profile is critical for understanding the remote sensing radiative transfer processes.

Congo Basin Carbon Cycle Responses to Global Change

Global Change Biology, Volume 32, Issue 1, January 2026.
Understanding the resilience of the Congo Basin carbon cycle in the face of current and future pressures requires a detailed understanding of its response to past and present drivers of change. Building on a pantropical framework of drivers and possible regional mechanisms for resilience, this review provides the first comprehensive assessment of Congo

Mapping the density of giant trees in the Amazon

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Spatiotemporal Dynamics and Controls of Vegetation Net Primary Production at Greater Bay Area Outer Ecological Barrier

Biological Diversity, Volume 2, Issue 4, Page 154-162, December 2025.
The spatiotemporal dynamics of NPP were evaluated for the ecological barrier of GBA, utilizing vegetation remote sensing, land use, and meteorological data. Results revealed that the vegetation NPP in the ecological barrier was 2.29 times that of the core area of GBA, highlighting its critical ecological function.

Utilizing People‐Centered Evaluation Approaches to Advance Racial Equity

New Directions for Evaluation, Volume 2025, Issue 188, Page 31-41, Winter 2025.
ABSTRACT Derived from a larger qualitative study examining how social justice‐oriented evaluators conceptualize, operationalize, and advance racial equity and justice in their practice, we draw on the reflective accounts of 29 evaluators to ask: How do social justice‐oriented evaluators center people when aiming to advance racial equity and justice? We
