Dataset Abstract

Samples of insects and spiders directly from randomly selected saplings of the Comparative Study Plots, obtained with beating tray sampling. Enables to test to what extent woody plant diversity affects the abundance, species composition and diversity of herbivores (which might profit from better resource availability if they are generalist feeders) and predators (which might profit from higher structural diversity or better resource availability in more plant diverse plots), and whether the top-down impact of predators on herbivores increases with plant diversity.

Dataset Design

Three sampling campaigns (fall 2011, spring 2012, summer 2012); 25 randomly selected tree and shrub saplings along transect cutting through each CSP; arthropods from each sapling knocked down by beating tree and collecting on beating tray; arthropods identified in the lab to higher taxa and, if possible, morhpospecies.

plot
Number of the Comparative Study Plot; Datagroup description: BEF research plot name; Datagroup description: Reasearch 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 A. 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.
