Data are of a literature review conducted by to study plant phenological cues (e.g., to temperature, precipitation, photoperiod, irradiance etc.) using ISI Web of Science. The data were used in the following publication (see especially the 'Appendix S1. Literature review description and references' for methods): Pau, S., Wolkovich, E. M., Cook, B. I., Davies, T. J., Kraft, N. J. B., Bolmgren, K., Betancourt, J. L. and Cleland, E. E. (2011), Predicting phenology by integrating ecology, evolution and climate science.
