Dataset Abstract

Trap nests (eigth traps per plot; four traps each attached to a wooden post; located at two randomly selected corners the corners of the central 10 x 10 m subplot) were used to collect solitary bees and wasps in the CSPs. Abundance and species richness of bees and wasps allow to test to which extent woody plant species richness affects the abundance, species composition and diversity of, e.g. predators (which might profit from higher structural diversity or better resource availability in more plant diverse plots) or pollinators (which might profit from more diverse flower resources). Traps consisted of plastic tubes (diameter 12.5 cm, length 22 cm) that were filled with dried internodes of the ree Arundo donax L. (2-20 mm diameter). Trap nests were exposed from August 2011 to October 2012. All trap nests were checked monthly for nests of solitary bees and wasps. These were then reared in the laboratory till hatching. Taxa were first sorted to morphospecies and then identified to species level with the help of taxonomic experts whenever possible.

Data Analysis

The data allow to test to what extent woody plant species richness affects the abundance, species composition and diversity of, e.g. predators (which might profit from higher structural diversity or better resource availability in more plant diverse plots) or pollinators (which might profit from more diverse flower resources) --- As in Hymenoptera most ecological information is shared between members of a family, the family names are provided as separate data colum. ---- Individual numbers presented are brood cell numbers, i.e. the number of brood cells provisioned by each species in a given trap.

Data columns available in the raw data part of this dataset

CSP
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.
