Observed Spring Phenology Responses in Experimental Environments (OSPREE)

This meta-analytic database of the published literature on spring phenology (e.g., budburst or leafout) of woody species in controlled environments (e.g., growth chambers) was designed to better inform models and related forecasts of spring phenology by: (1) allowing tests of the relative effects of chilling, forcing and photoperiod (daylength) on spring phenological responses and (2) giving an overview of the design of most experimental studies to date. There are four versions of this dataset: 1) ospreebb_forknb.csv: a subset of the full database focused on budburst, used in Ettinger, A.K., Chamberlain, C.J., Morales-Castilla, I., Buonaiuto, D.M., Flynn, D.F.B., Savas, T., Samaha, J.A. and Wolkovich, E.M., 2020. Winter temperatures predominate in spring phenological responses to warming. Nature Climate Change, 10(12), pp.1137-1142. 2) ospree_forknb_limcue.csv: the full database, used in E.M. Wolkovich,, C.J. Chamberlain, D.M. Buonaiuto, A.K. Ettinger, I. Morales-Castilla. 2022. Limiting cues: How spring warming, winter chilling and daylength shape climate change responses. New Phytologist. 3) ospreebb2019update_forknb.csv: an update to the budburst database above, which includes additional datasets added in 2019 (see Methods for details). 4) ospreebbphyloms_forknb.csv: a subset of the updated budburst database above, used in Morales-Castilla, I., et al.
