Journal ArticleDOI
Root biomass allocation in the world's upland forests.
TL;DR: In this article, the root biomass density is estimated based on existing data from the literature and linear regression analysis is used to determine if a reliable method to estimate root density for forests could be developed.
Journal ArticleDOI

TL;DR: Free imagery will enable reconstruction of the history of Earth's surface back to 1972, chronicling both anthropogenic and natural changes during a time when the authors' population doubled and the impacts of climate change became noticeable.
Journal ArticleDOI
Plant diversity patterns in neotropical dry forests and their conservation implications

TL;DR: Using 835 inventories covering 4660 species of woody plants, marked floristic turnover among inventories and regions indicates that numerous conservation areas across many countries will be needed to protect the full diversity of tropical dry forests.
Journal ArticleDOI
A flexible spatiotemporal method for fusing satellite images with different resolutions
TL;DR: A new spatiotemporal data fusion method that uses simple principles and needs only one fine-resolution image as input has the potential to increase the availability of high-resolution time-series data that can support studies of rapid land surface dynamics.
Journal ArticleDOI

TL;DR: In this paper, a spatially explicit dataset of aboveground live forest biomass was made from ground measured inventory plots for the conterminous U.S., Alaska and Puerto Rico.
