Journal of Biogeography SUPPORTING INFORMATION Climatic drivers of trait assembly in woody plants in Japan Takayuki Shiono, Buntarou Kusumoto, Ryo Maeshiro, Shin-Jiro Fujii, Lars Götzenberger, Francesco de Bello and Yasuhiro Kubota Appendix S1 Source references for the geographical database of woody plants in Japan. Distributional data for woody plant species were collected by searching the botanical literature on the flora of the Japanese archipelago. Most of the references that we searched were species checklists and phytosociological tables. The titles for 226 of the 461 references have been translated from the Japanese original sources. Abe, C.
