Enhanced ultraviolet-B radiation (UV-B, 280–320 nm) is recognized as one of the environmental stress factors that cannot be neglected. Jasmonic acid (JA) is an important signaling molecule in a plant’s defense against biotic and abiotic stresses. To determine the role of exogenous JA in the resistance of wheat to stress from UV-B radiation, wheat seedlings(More)
Problem Forest canopy height is essential information for many forest management activities and is also a critical parameter in models of ecosystem processes and in better quantifying the terrestrial carbon cycle [1, 2]. Several categories of methods are available to measure canopy height from remote sensing technology, one of which is the Polarimetric(More)
Forest aboveground biomass (AGB) was mapped throughout China using large footprint LiDAR waveform data from the Geoscience Laser Altimeter System (GLAS) onboard NASA's Ice, Cloud, and land Elevation Satellite (ICESat), Moderate Resolution Imaging Spectro-radiometer (MODIS) imagery and forest inventory data. The entire land of China was divided into seven(More)
Synthetic Aperture Radar is the only instrument that can provide consistent remote sensing data for south China with persistent cloud cover and rain. It is generally difficult to acquire specified optical remote sensing images for interpretation due to frequent cloud and fog covers in subtropical area of southeastern China. Land cover mapping and timely(More)
(1) The effects of facilitation on the structure and dynamics of plant populations have not been studied so widely as competition. The UV-B radiation, as a typical environmental factor causing stress, may result in direct stress and facilitation. (2) The effects of UV-B radiation on intraspecific competition and facilitation were investigated based on the(More)
