ReadMe for "Trade-offs in parasitism efficiency and brood size mediate parasitoid coexistence" test results, Authors: Xiao-Yi Wang, David E. Jennings, Jian J. Duan 2015-6-19 This readme file describes the data files associated the above publication. For any further queries please contact xywang@caf.ac.cn The following files are included: 1) "Host and Parasitoid density.xlsx" This is the original dataset on the determination of effects of Host and Parasitoid density on the competetion between two species of parasitoid Tetrastichus planipennisi and Spathius galinae of the invasive emerald ash borer. The explanation of the variables is included in the manuscript, section "Materials and Methods" or "Figure legend"". 2) "Host plant size.xlsx" This is the original dataset on the determination of effects of Host plant sizes on the competetion between two species of parasitoid Tetrastichus planipennisi and Spathius galinae of the invasive emerald ash borer. The explanation of the variables is included in the manuscript, section "Materials and Methods" or "Figure legend"". 3) "Parasitoid-host ratio.xlsx" This is the original dataset on the determination of effects of Parasitoid-host ratio on the competetion between two species of parasitoid Tetrastichus planipennisi and Spathius galinae of the invasive emerald ash borer. The explanation of the variables is included in the manuscript, section "Materials and Methods" or "Figure legend"".
