Dataset Abstract

This dataset provides information about the remaining leaf litter mass of the Unlabelled NILEx litter decomposition plots.

Dataset Design

11 leaf decomposition plots per block with 10 mesocosms, four with mesofauna exclusion (timesteps 1-4, mesh size 15 mm), four with mesofauna inclusion (timesteps 1-4, mesh size 0,25 mm), one backup mesocosm with mesofauna exclusion (sampled at timestep 3)

Spatial Extent

Castanea mollissima plantation near site B

Taxonomic Extent

Species pool 1 (block 1 and 3): Senescent leaves of Liquidambar formosana, Machilus thunbergii, Quercus serrata, Schima superba; Species pool 2 (block 2 and 4): Schima superba, Castanopsis eyrei, Castanea henryi, Cyclobalanopsis glauca;
Leaves were used to create all possible monoculture, 2- and 4- species mixtures per species pool

Measurement Circumstances

Damage of block 1 & 3 before timestep 3; Leaves were very dirty and it was hard to clean and separate them according to species

Data Analysis

Leaves of two mesocosms per plot (one of each treatment) were sampled at 4 timesteps. The leaves were cleaned, separated according to species, died at 40°C and weighted. The dataset shows the remaining litter mass in gram an percent for all timesteps for the species mixture.
