Woody debris, which is supplied by branch litter, is an important component of forest ecosystems as it contains large quantities of organic matter and nutrients. We evaluated changes in branch wood dry weight and nutrient content of six common species (Fraxinus rhynchophylla, Pinus densiflora, Prunus sargentii, Quercus mongolica, Acer pseudosieboldianum, and Symplocos chinensis for. pilosa) in ...

Interactions among plants have been hypothesized to be context dependent, shifting between facilitative and competitive in response to variation in physical and biological stresses. This hypothesis has been supported by studies of the importance of positive and negative interactions along abiotic stress gradients (e.g., salinity, desiccation), but few studies have tested how variation in biotic...

Overwintering and spring recovery of pine needles have important ecological significance. The natural changes in physiological state, photosynthetic function, material metabolism Pinus densiflora Siebold & Zucc. from the autumn 2020 to 2021 were assessed. rate (Pn) P. decreased first then increased, with maximum Pn observed autumn. After experiencing sub-zero temperatures winter, still perf...
