Name:
SP01c Effects of species richness and composition on belowground net primary productivity in subtropical forest ecosystems
Description:
Due to the large area, high primary productivity, and carbon stock, forests play a critical role in global carbon cycling and their responses and feedbacks to global climate change. Belowground net primary productivity (BNPP) in forests determines soil organic C pools, in which the majority of forest carbon stocks are located. Our understanding of the responses of BNPP to biodiversity, especially in forests, is extremely limited irrespective of the welldocumented impacts of biodiversity on aboveground biomass productivity across various biomes. In addition to the effects of tree species richness, identity and composition, we will ask how different canopy groups (upper canopy trees, understory shrubs, herbaceous species) in forests affect the spatial and temporal variability of BNPP. The Biodiversity–Ecosystem Functioning Experiment in the subtropical forest in China provides us with a unique opportunity to address the above issues. This subproject will examine the responses of BNPP to tree and shrub species diversity and estimate the relative contributions of canopy trees, understory shrubs, and herbaceous species to BNPP and to the spatial and temporal variability of BNPP. Using measured covariables, we will analyze both direct and indirect effects of biodiversity, including indirect effects via altered soil moisture, temperature, nutrient availability, and soil fauna.

CSPs: Abundances of arthropod morphospecies, orders and feeding guilds captured on yellow sticky traps in the CSPs (1-15) 2010

Abstract:
To test the effect of biodiversity on arthropod pattern in the CSP we put 10 yellow sticky traps in each CSP. 5 traps are at 2 m from the ground and 5 traps were set up within the tree crown. The arthropod were then counted on each trap, separati...

CSPs: subplot naming conventions

Abstract:
Subplot naming conventions refer not only to the CSP and the geographic direction (provided by M. Baruffol) but also by the subplot location within the slope (X. Chi).

Effect of clear-cutting silviculture on soil respiration in a subtropical forest of China

Abstract:
Aims Clear-cutting is a common forest management practice, especially in subtropical China. However, the potential ecological consequences of clear-cutting remain unclear. In particular, the effect of clear-cutting on soil processes, such as the ...

Inter- and intraspecific variation in specific root length drives aboveground biodiversity effects in young experimental forest stands

Abstract:
Aims Although the net biodiversity effect (NE) can be statistically partitioned into complementarity and selection effects (CE and SE), there are different underlying mechanisms that can cause a certain partitioning. Our objective was to assess t...
