Atmospheric carbon dioxide (CO2) and global mean temperature are expected to be significantly higher by the end of the 21st century. Elevated CO2 (eCO2) and higher temperature each affect plant physiology and growth, but their interactive effects have not been reviewed statistically with respect to higher chronic mean temperatures and abrupt heat stress. In(More)
Reproduction is an important life history trait that strongly affects dynamics of plant populations. Although it has been well documented that elevated carbon dioxide (CO2) in the atmosphere greatly enhances biomass production in plants, the overall effect of elevated CO2 on reproductive allocation (RA), i.e., the proportion of biomass allocated to(More)
Recently, a coding scheme called vector of locally aggregated descriptors (VLAD) has got tremendous successes in large scale image retrieval due to its efficiency of compact representation. VLAD employs only the nearest neighbor visual word in dictionary to aggregate each descriptor feature. It has fast retrieval speed and high retrieval accuracy under(More)
Due to its excellent glass-forming ability (GFA), the Zr 48 Cu 36 Al 8 Ag 8 bulk metallic glass (BMG) is of great importance in glass transition investigations and new materials development. However, due to the lack of detailed structural information, the local structure and atomic packing of this alloy is still unknown. In this work, synchrotron(More)
The endangered status and narrow distribution in Syringa pinnatifolia , a sub-alpine shrub species, were primarily caused by its poor drought adaptation related to its lower degree of physiological adjustment despite its greater degree of morphological plasticity. Although deep rooting is usually considered a drought-tolerant trait, we found that Syringa(More)
White birch (Betula paperifera Mash) seedlings were exposed to progressively warming in greenhouses under ambient and elevated CO 2 concentrations for 5 months to explore boreal tree species' potential capacity to acclimate to global climate warming and CO 2 elevation. In situ foliar gas exchange, in vivo carboxylation characteristics and chlorophyll(More)
