Complete data set for seed germination experiment with Lasthenia californica, L. fremontii, and L. glaberrima

Complete data set of seed germination and viability from: Van Den Elzen, C.L. and N.C. Emery. 2025. Recruitment in variable environments: plasticity and bet hedging in the timing of seed germination in three closely related species. Annals of Botany. Abbreviations used in data spreadsheet: Code in data sheet Full name Explanation G germinated seed germinated during the experiment MS missing seed seed went missing during th experiment NV not viable seed was dissected at the end of the experiment but the embryo had no reaction to tetrazolium or only partial staining occurred MO moldy seed became moldy and was removed from the experiment R ruined embryo was ruined on dissection NE no embryo no embryo present on dissection V viable embryo present on dissetion and had a positive reaction to tetrazolium (full staining) MD missing data no data written into the data sheet or data written in was not valid. Data tables: 2021_Germination_Study_Survey_Data.csv: raw germination timing data. 2020_germexp_seed_mass_ds_gla.csv: raw L. glaberrima seed mass data. 2020_germexp_seed_mass_ds_cal.csv: raw L. californica seed mass data. 2020_germexp_seed_mass_ds_fre.csv: raw L. fremontii seed mass data. germination_timing_conversion_table.csv: key for germination date correction using germinant size class. germ_mass_dat_germinants.csv: cleaned germination and seed mass data for import to SAS. GermTiming_Variances.csv: SAS export of model variance values for plotting of model results. GermTiming_Means.csv: SAS export of model mean values for plotting of model results. Scripts: data_cleaning.R: takes raw data files (see above), cleans the data, corrects germination dates using germinant size class, and exports the clean data for use in SAS modelling. Van Den Elzen and Emery_2025_Annals-of-Botany_SAS-heterogeneous-variance-code.docx: SAS statsitical modeling code, starting from clean data. figure_code.R: code to create all data figures in the manuscript (figures 2-4). Figures 3 and 4 are created using SAS model result export tables (see above).
