Abstract:
All plots from site B in the main experiment, their plot names, treatment information, planned richness in trees and shrubs, longitude and latitude and topographic information.
Design:
Describing the A random extinction series along a broken stick random arrangement crossed with an shrub extinction series and replicated once, the B and C broken stick random extinction as well as the two directed extinction series with decreasing SLA (S) and decreasing rareness (R), plus economic treatments (E). Site B also includes a Genetic diversity treatment (G). Topographic variables (altitude, inclination, exposition) are mean values based on the 5m GIS.
Spatial extent:
Site B of the Main Experiment
Temporal extent:
Last updated January 2014
Taxonomic extent:
Species information only in comments, this is the plot related data.
Measurement cirumstances:
No information available
Data analysis:
Topographic variables can be used as covariates for plot performance.

plot code, BEF research plot name, 6 digits with "p" in front; Datagroup description: Research plots of the Biodiversity - Ecosystem functioning experiment (BEF-China). There are three main sites for research plots in the BEF Experiment: Comparative Study Plots (CSP) in the Gutianshan Nature Reserve, having a size of 30x30m^2, measured on the ground. 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.; Datagroup description: Reasearch plots of the Biodiversity - Ecosystem functioning experiment (BEF-China).

Early positive effects of tree species richness on herbivory in a large-scale forest biodiversity experiment influence tree growth

Abstract:
Despite the importance of herbivory for the structure and functioning of species-rich forests, little is known about how herbivory is affected by tree species richness, and more specifically by random versus nonrandom species loss. We assessed her...

Ants at plant wounds - A little-known trophic interaction with evolutionary implications for ant-plant interactions

Abstract:
Extrafloral nectaries (EFNs) allow plants to engage in mutualisms with ants preventing herbivory in exchange for food. EFNs occur scattered through the plant phylogeny and likely evolved independently from herbivore-created wounds subsequently vis...

Soil and tree species traits both shape soil microbial communities during early growth of Chinese subtropical forests

Abstract:
A better understanding of the linkages between aboveground and belowground biotic communities is needed for more accurate predictions about how ecosystems may be altered by climate change, land management, or biodiversity loss. Soil microbes are s...
