Name:
SP05e Effects of environmental conditions and biodiversity on litter decomposition and nutrient cycling in subtropical forests in China
Description:
In the first phase of BEF-China, Subproject 5 has quantified key pools and fluxes of the
nitrogen cycle and in close cooperation with the Chinese counterparts also those of the
carbon cycle. These measurements were done in the Comparative Study Plots of the Nature
Reserve in Gutianshan. In addition, subproject 5 has worked in the Pilot Experiment on
belowground spatio-temporal-chemical resource complementarity of nitrogen.
In the second phase of the Research Unit, subproject 5 will focus on litter decomposition as a
key process in nutrient cycling. Several lines of experimentation will yield insights on
controlling factors of litter decomposition, including abiotic and biotic components of the
ecosystem. Adopting the “ecoscapes” approach, we will quantify the effects of topography
and micro-relief on decomposition dynamics. Subproject 5 will take the lead to establish
NILEx, the New Integrated Litter decomposition Experiment that combines the quantification
of diversity effects on decomposition processes, nutrient uptake and microbial use, and soil
erosion.

CSPs: Gaseous concentration of nitrogen dioxide (NO2) and ammonia (NH3) for estimating dry deposition of nitrogen in the GNNR
Abstract:
Gaseous concentration of nitrogen dioxide (NO2) and ammonia (NH3) was measured in Gutianshan for a period of 12 months (November 2008 - October 2009) for estimating dry deposition of nitrogen. Passive sampling tubes (www.passam.ch) were used to qu...
