We would like to thank Stephen Long for the invitation to contribute to the special issue celebrating the 25th anniversary of Global Change Biology and the Executive Editor Rachel Shekar for her extraordinary support and patience handling this manuscript. We also thank the publisher for excellent support. We thank the two anonymous reviewers for valuable suggestions, which helped to substantially improve the manuscript. The TRY database is hosted, developed and maintained at the Max Planck Institute for Biogeochemistry (MPI‐BGC) in Jena, Germany, in collaboration with the German Centre for Integrative Biodiversity Research (iDiv) Halle‐Jena‐Leipzig. The TRY database receives additional funding by the Max Planck Society via the Max Planck Fellow Program for Christian Wirth. In addition, the TRY initiative has been supported by the International Programme of Biodiversity Science (DIVERSITAS), the International Geosphere‐Biosphere Programme (IGBP), Future Earth, the French Foundation for Biodiversity Research (FRB), and GIS ‘Climat, Environnement et Société’ France. The TRY initiative is grateful for major support by Linda Maack and the IT Department at the MPI‐BGC. We would like to thank all data contributors to TRY, who are not co‐authors of this paper, that is Pierre Meerts, Jennifer Powers, Nina Koele, Henrik Balslev, John Briggs, Michael White and Robin Chazdon. V.O. thanks RSF (#19‐14‐00038). S.D. thanks CONICET, FONCyT and IAI. Finally, the TRY initiative is very grateful to all the numerous scientists not mentioned here measuring plant traits: without their work the TRY database would not exist. Author contribution - Jens Kattge, Gerhard Bönisch, Sandra Díaz, Sandra Lavorel, Iain Colin Prentice, Paul Leadley and Christian Wirth developed the concept and draft manuscript. Susanne Tautenhahn and Gijsbert Werner contributed analyses and plots for Figures 9, 10 and 11. The other authors contributed plant trait data and/or supported data curation and analysis.
