In this study, we investigated responses of the mid-successional species Acer truncatum Bunge and the late-successional species Quercus variabilis Blume to three solar illumination conditions: (1) constant low light (CL), (2) constant high light (CH) and (3) low light first and high light afterwards (LH). The last treatment was to simulate a canopy opening. Both species exhibited increases in biomass,...
In order to explore the composition characteristics and distribution pattern of organic carbon (OC) in river sediments, river sediments and riverbank soils were sampled from upstream to downstream of the Majia and Tuhai rivers in northern China, and then determined for heavy fraction organic carbon (HFOC) and light fraction organic carbon (LFOC). Results showed that the HFOC had a significant correlation...
Leaf traits scaling relationships were compared in different months (May, June, July and August) in a temperate shrub species, Vitex negundo Linn. var. heterophylla (Franch.) Rehd. Leaf traits variation and the impact of environment were also studied. Our results showed that specific leaf area (SLA), leaf nitrogen content (Nmass), leaf phosphorus content (Pmass) and leaf chlorophyll content (Chlmass)...
