Aboveground biomass in Tibetan grasslands
This study investigated spatial patterns and environmental controls of aboveground biomass (AGB) in alpine grasslands on the Tibetan Plateau by integrating AGB data collected from 135 sites during 2001– 2004 and concurrent enhanced vegetation index derived from MODIS data sets. The AGB was estimated at 68.8 gm 2, with a larger value (90.8 gm 2) in alpine meadow than in alpine steppe (50.1 gm 2)...
متن کاملTumour radiobiology beyond fractionation
Historically it has been shown repeatedly that single high doses of radiation do not allow a therapeutic differential between tumor and critical normal tissues but dose fractionation does. The purpose of conventional dose fractionation is to increase dose to the tumor while preserving normal tissue function. Tumors are generally irradiated with 2Gy dose per fraction delivered daily to a more or...
متن کاملGilles Deleuze: Beyond Peirce’s Semiotics
This paper studies the role of the semiotic discussions of Charles Sanders Peirce, the American philosopher and mathematician, in the formation of Deleuze’s first leading book on cinema, Cinema 1: the Movement-Image,in whichthe author surpasses Peirce’s semiotics. We will show how Deleuze creates a new form of signs in his second leading book on cinema, Cinema 2: the Time-Image. Deleuze had tri...
متن کاملUrban warming reduces aboveground carbon storage.
A substantial amount of global carbon is stored in mature trees. However, no experiments to date test how warming affects mature tree carbon storage. Using a unique, citywide, factorial experiment, we investigated how warming and insect herbivory affected physiological function and carbon sequestration (carbon stored per year) of mature trees. Urban warming increased herbivorous arthropod abund...
متن کاملEcological linkages between aboveground and belowground biota.
All terrestrial ecosystems consist of aboveground and belowground components that interact to influence community- and ecosystem-level processes and properties. Here we show how these components are closely interlinked at the community level, reinforced by a greater degree of specificity between plants and soil organisms than has been previously supposed. As such, aboveground and belowground co...
