Abstract:
The BEFmod experiment is subject to a manipulation of resource supply and biotic impacts to examine whether Biodiversity-Ecosystem-Functioning (BEF) relationships may change under different environmental influences. BEFmod was conducted on subplots in each VIP plot in the Main Experiment and started in 2014. A total of five subplots (designated A to E) were established on the four northern planting rows of each VIP plot. Each subplot is of an area of 5.16 x 5.16m and contains 4 x 4 tree planting positions. Subplots were randomly assigned to five different treatments: Insecticide application, aboveground fungicide application, phosphorous fertilization, partial weeding and no weeding. Tree crown characteristics strongly determin the magnitude of light capture (Binkley et al. 2013) and have been commonly used to predict tree growth rates (e.g. Pretzsch 2009). Canopy stratification is proposed and also has been evidenced to be one key complementarity mechanism for the positive biodiversity and plant productivity relationship (Menalled et al. 1998, Morin et al. 2011). We, therefore, measured the crown diameter and crown base height of each tree individuals on all subplots in each VIP plot.In line with the objective of BEFmod, we aim to investigate density-dependent and resource-rich based mechanisms affecting the response of canopy characteristics at community level.

Definition:
plot code, BEF research plot name, 6 digits with "p" in front; Datagroup description: Research plots of the Biodiversity - Ecosystem functioning experiment (BEF-China). Main Experiment plots have a size of 1 mu, which is about 25x25m^2 in horizontal projection. Pilot Study Plots have a size of 1x1 m^2. Research plots on the main experiment have a "p" in front of their IDs and then a 6 digit code: Plots in the main sites A and B are named according to their position in the original spreadsheet, in which they were designed. They consist of 6 digits: _1st digit_: Site (1:A, 2:B), _digit 2and3_: southwards row: as in spreadsheets the rows are named from the top to the bottom; _digit 4 and 5_: westward column: as in the original spreadsheet, but the letters are converted to numbers (A=01, B=02); _6th digit_: indicator, if the plot has been shifted a quarter mu. Example: "p205260": "p" means that this is a plot that is specified. "2" means, that we are at site B. Now the coordinates of the south - west corner: "0526". Since "e" is the fifth letter of the alphabet, this is Plot E26. The last digit "0" means that this plot was not moved by a quarter of a Mu, as some sites in Site B. The 6th digit can also indicate the subplot within the plot. "5", "6", "7", "8" indicate the northwest, northeast, southeast, and southwest quarter plot respectively.
