Analyses of various biophysical and biochemical factors affecting plant canopy reflectance
have been carried out over the past few decades, yet the relative importance of these factors …

Amazon deforestation has been measured by remote sensing for three decades. In
comparison, selective logging has been mostly invisible to satellites. We developed a large-scale, …

Land use has generally been considered a local environmental issue, but it is becoming a
force of global importance. Worldwide changes to forests, farmlands, waterways, and air are …

Aim We present the first global synthesis of plant canopy leaf area index (LAI) measurements
from more than 1000 published estimates representing ∼400 unique field sites. LAI is a …

Efforts to mitigate climate change through the Reduced Emissions from Deforestation and
Degradation (REDD) depend on mapping and monitoring of tropical forest carbon stocks and …

▪ Abstract Managed grazing covers more than 25% of the global land surface and has a
larger geographic extent than any other form of land use. Grazing systems persist under …

This paper contrasts the natural and anthropogenic controls on the conversion of unreactive
N 2 to more reactive forms of nitrogen (Nr). A variety of data sets are used to construct global …

The ranges of plants and animals are moving in response to recent changes in climate 1 . As
temperatures rise, ecosystems with ‘nowhere to go’, such as mountains, are considered to …

Biological invasions contribute to global environmental change, but the dynamics and
consequences of most invasions are difficult to assess at regional scales. We deployed an …

The long-term viability of a forest industry in the Amazon region of Brazil depends on the
maintenance of adequate timber volume and growth in healthy forests. Using extensive high-…
