Leveraging the next generation of spaceborne Earth observations for fuel monitoring and wildland fire management

Remote Sensing in Ecology and Conservation, Volume 11, Issue 2, Page 133-155, April 2025.
This paper presents an interdisciplinary perspective of the next generation of spaceborne remote sensors applied to wildland fire management. We highlight the potential improvements in fuel characterization at large scale arising from the use of new spaceborne instruments with near‐global, freely‐available data.

Relationship Between Plant Diversity and Soil Environment in Karst Urban Remnant Mountains: A Comparative Analysis of Two Types

Ecology and Evolution, Volume 15, Issue 3, March 2025.
The transformation of karst urban remnant mountains into mountain parks had not only simplified the composition of plant species and reduced biodiversity, but also changed the characteristics of soil environmental factors and their distribution pattern with plant diversity, thus reshaping their mutual relationship.
