Ongoing climate change poses significant threats to plant function and distribution.
Increased temperatures and altered precipitation regimes amplify drought frequency and …

The geometries and topologies of leaves, flowers, roots, shoots, and their arrangements
have fascinated plant biologists and mathematicians alike. As such, plant morphology is …

A prominent signal of the Anthropocene is the extinction and population reduction of the
megabiota—the largest animals and plants on the planet. However, we lack a predictive …

Attributes that describe forest structure, such as height, canopy cover, volume, and biomass,
are required to inform forest inventories and monitoring programs. Light Detection and …

Abstract NASA's Global Ecosystem Dynamics Investigation (GEDI), to be deployed on the
International Space Station (ISS) in 2018, will provide billions of measurements of ground …

Abstract Interferometric Synthetic Aperture Radar (InSAR) and lidar are increasingly used
active remote sensing techniques for forest structure observation. The TanDEM-X (TDX) …

Prompted by laser scanning (LS), point clouds have been applied in forest biomass
estimation for three decades. Previously reported evaluations focused on the accuracy of …

Forests provide essential ecosystem services and hold approximately 45% of global
terrestrial carbon. Estimates of the quantity and spatial distribution of global forest carbon …

Tropical tree size distributions are remarkably consistent despite differences in the
environments that support them. With data analysis and theory, we found a simple and …

Abstract The Global Ecosystem Dynamics Investigation (GEDI) lidar is a multibeam laser
altimeter on the International Space Station (ISS). GEDI is the first spaceborne instrument …
