Journal ArticleDOI
Redefining fine roots improves understanding of below-ground contributions to terrestrial biosphere processes
M. Luke McCormack,Ian A. Dickie,David M. Eissenstat,Timothy J. Fahey,Christopher W. Fernandez,Dali Guo,Heljä-Sisko Helmisaari,Erik A. Hobbie,Colleen M. Iversen,Robert B. Jackson,Jaana Leppälammi-Kujansuu,Richard J. Norby,Richard P. Phillips,Kurt S. Pregitzer,Seth G. Pritchard,Boris Rewald,Marcin Zadworny +16 more
TL;DR: It is demonstrated how order-based and functional classification frameworks improve the understanding of dynamic root processes in ecosystems dominated by perennial plants.
Journal ArticleDOI
Elevated CO2 and plant structure: a review
TL;DR: A review of the literature suggests that cell division, cell expansion, and cell patterning may be affected, driven mainly by increased substrate (sucrose) availability and perhaps also by differential expression of genes involved in cell cycling or cell expansion.
Journal ArticleDOI
Increases in the flux of carbon belowground stimulate nitrogen uptake and sustain the long‐term enhancement of forest productivity under elevated CO2
John E. Drake,Anne Gallet-Budynek,Anne Gallet-Budynek,Kirsten S. Hofmockel,Emily S. Bernhardt,Sharon A. Billings,Robert B. Jackson,Kurt S. Johnsen,John Lichter,Heather R. McCarthy,Heather R. McCarthy,M. Luke McCormack,David J. P. Moore,Ram Oren,Sari Palmroth,Richard P. Phillips,Jeffrey S. Pippen,Seth G. Pritchard,Kathleen K. Treseder,William H. Schlesinger,Evan H. DeLucia,Adrien C. Finzi +21 more
TL;DR: It is shown that consistently enhanced rates of net primary production are sustained by a C-cascade through the root-microbe-soil system; increases in the flux of C belowground under elevated CO₂ stimulated microbial activity, accelerated the rate of soil organic matter decomposition and stimulated tree uptake of N bound to this SOM.
Journal ArticleDOI
Increases in nitrogen uptake rather than nitrogen-use efficiency support higher rates of temperate forest productivity under elevated CO2
Adrien C. Finzi,Richard J. Norby,Carlo Calfapietra,Anne Gallet-Budynek,Birgit Gielen,William E. Holmes,Marcel R. Hoosbeek,Colleen M. Iversen,Robert B. Jackson,Mark E. Kubiske,Joanne Ledford,Marion Liberloo,Ram Oren,Andrea Polle,Seth G. Pritchard,Donald R. Zak,William H. Schlesinger,Reinhart Ceulemans +17 more
TL;DR: Experimental evidence demonstrates that the uptake of N increased under elevated CO2 at the Rhinelander, Duke, and Oak Ridge National Laboratory FACE sites, yet fertilization studies showed that tree growth and forest NPP were strongly limited by N availability.
Journal ArticleDOI
Re-assessment of plant carbon dynamics at the Duke free-air CO 2 enrichment site: interactions of atmospheric [CO 2 ] with nitrogen and water availability over stand development
Heather R. McCarthy,Heather R. McCarthy,Ram Oren,Kurt H. Johnsen,Anne Gallet-Budynek,Seth G. Pritchard,Charles W. Cook,Shannon L. LaDeau,Robert B. Jackson,Adrien C. Finzi +9 more
TL;DR: It is shown that net primary productivity enhancement by elevated [CO(2)] is not uniform, but rather highly dependent on the availability of other growth resources, with the difference between precipitation and potential evapotranspiration explaining most interannual variability.
