Title:
Community assembly of ectomycorrhizal fungi along a subtropical secondary forest succession

Rationale:
 Environmental selection and dispersal limitation are two of the primary processes structuring biotic communities in ecosystems, but little is known about these processes in shaping the soil microbial community during secondary forest succession.  We examined the community of ectomycorrhizal (EM) fungi in young, intermediate and old forests in a Chinese subtropical ecosystem, using 454 pyrosequencing.  The EM fungal community consisted of 393 operational taxonomic units (OTUs), belonging to 21 EM fungal lineages, in which three EM fungal lineages and 11 EM fungal OTUs showed significantly biased occurrence among the young, intermediate and old forests. The EM fungal community was structured by environmental selection and dispersal limitation in old forest, but only by environmental selection in young, intermediate, and whole forests. Furthermore, the EM fungal community was affected by different factors in the different forest successional stages, and the importance of these factors in structuring EM fungal community dramatically decreased along the secondary forest succession series.  This study suggests that different assembly mechanisms operate on the EM fungal community at different stages in secondary subtropical forest succession.

CSPs: Herb layer plant biomass in the CSPs, separated into functional groups (2008)

Abstract:
Biomass is a proxy for assessing herb layer productivity. In contrast to most traits it is easy practicable and therefore feasible repeatedly. Since the proportion of functional groups is informative for community structure biomass was harvested s...

CSPs: Litter layer thickness, mass and C and N pools at the forest floor

Abstract:
Thickness and mass of the standing leaf litter layer was measured in all CSPs in spring 2009, summer 2009, autumn 2009 and winter 2010. This piece of work will contribute to calculate total carbon and nitrogen pool sizes of the broad-leaved fore...
