Global Consequences of Land Use
Jonathan A. Foley,Ruth DeFries,Gregory P. Asner,Carol C. Barford,Gordon B. Bonan,Stephen R. Carpenter,F. Stuart Chapin,Michael T. Coe,Michael T. Coe,Gretchen C. Daily,Holly K. Gibbs,Joseph H. Helkowski,Tracey Holloway,Erica A. Howard,Christopher J. Kucharik,Chad Monfreda,Jonathan A. Patz,I. Colin Prentice,Navin Ramankutty,Peter K. Snyder +19 more
TL;DR: Global croplands, pastures, plantations, and urban areas have expanded in recent decades, accompanied by large increases in energy, water, and fertilizer consumption, along with considerable losses of biodiversity.
Journal ArticleDOI
The velocity of climate change
Scott R. Loarie,Philip B. Duffy,Philip B. Duffy,Healy Hamilton,Gregory P. Asner,Christopher B. Field,David D. Ackerly +6 more
TL;DR: A new index of the velocity of temperature change (km yr-1), derived from spatial gradients and multimodel ensemble forecasts of rates of temperature increase in the twenty-first century, indicates management strategies for minimizing biodiversity loss from climate change.
Journal ArticleDOI
PROSPECT+SAIL models: A review of use for vegetation characterization
Stéphane Jacquemoud,Wout Verhoef,Frédéric Baret,Cédric Bacour,Pablo J. Zarco-Tejada,Gregory P. Asner,C. François,Susan L. Ustin +7 more
TL;DR: The combined PROSPECT leaf optical properties model and SAIL canopy bidirectional reflectance model, also referred to as PROSAIL, has been used for about sixteen years to study plant canopy spectral and directional reflectance in the solar domain this paper.
Journal ArticleDOI
Biophysical and Biochemical Sources of Variability in Canopy Reflectance
TL;DR: In this article, a combination of field and modeling techniques were used to quantify the relative contribution of leaf, stem, and litter optical properties (incorporating known variation in foliar biochemical properties) and canopy structural attributes to nadir-viewed vegetation reflectance data.
Journal ArticleDOI
Grazing systems, ecosystem responses, and global change
Gregory P. Asner,Gregory P. Asner,Andrew J. Elmore,Lydia Olander,Roberta E. Martin,A. Thomas Harris +5 more
TL;DR: In this paper, the authors identified three regional syndromes inherent to global grazing: desertification, woody encroachment, and deforestation, which have widespread but differential effects on the structure, biogeochemistry, hydrology and biosphere-atmosphere exchange of grazed ecosystems.
