**Description of datasets** --------------------------- ---------- *site_meta : Tables containing sites level data (CSV file)* The study design and site selection explained in Klanderud et al. 2015. Each observation is a site. - site: Names of site (enable merging with other datasets) - temp.level: Temperature level within the SEEDCLIM climate grid. 1: alpine, 2: sub-alpine, 3: boreal - precip.level: Precipitation level within the SEEDCLIM climate grid. 1: dry, 2: mid-dry, 3: mid-wet, 4: wet - temp: Summer temperature of every site (C°) - precip: Annual precipitation of every site (mm) ---------- *recr : Tables containing data on seedling emergence, survival et establishment (CSV file)* The data are sourced from Berge (2010). Each observation is a monitored seedling, sampled from a 25 x 25 cm experimental plot. - site: Names of site Treat = 3 levels variables; RTG: plot with existing above-and below-ground biomass removed; RTC: intact vegetation plots, RTS: Seedrain screening / exclusion plots (not used in this paper) - block: Block number. the experiment was replicated in 3 to 5 blocks per site - turfID: Unique ID of the plot - sp: Qualified guess of species ID recorded, cannot be trusted, not used in this study - abun: Abundance of the seedling, only 1, used to calculated emergence score in the script - est: Seedling establishment over the entire monitoring period; 1 for established seedling, NA otherwise - surv: Seedling survival over the entire monitoring period: S for established seedling, D for dead, NA for lost seedlings - death: Seedling mortality over the entire monitoring period: D for dead seedling, NA otherwise - E2010: Seedling establishment during the first year: E for established seedling, NA otherwise - surv2010: Seedling survival during the first year: S for established seedling, NA otherwise - death2010: Seedling mortality during the first year: D for dead seedling, NA otherwise - estD: Seedling establishment over the entire monitoring period with identification of dead seedlings; 1 for established seedling, D for dead seedlings, NA otherwise. ---------- *seedrain : Tables containing data on seed rain (CSV file)* The data are sourced from Berge (2010). Each observation is a 25 x 25 cm AstroTurf seedtrap. This dataset is used to extract seedrain data used for the calculation of seedling emergence rate. - BlockN: Block names. the experiment was replicated in 3 to 5 blocks per site. - Site: Names of site (enable merging with other datasets). - Block: Block number. the experiment was replicated in 3 to 5 blocks per site. -s/v: Summer (s) or winter (v) seed deposition. The analysis uses only summer deposition. - sum: Sum of seeds trapped ---------- *time2est: Tables enabling the study of establishment rates over times (CSV file)* The data are sourced from Berge (2010). Each observation is a 25 x 25 cm experimental plot. - PlotID: an ID of the experimental plot - Time: Id of the survey: 2 = month 1, 2 = month 12, 3 = month 14, 4 = month 24, 5 = month 26, 6 = month 38 - est = Number of established seedlings - non.est = Number of non established seedling - Site = names of site - block = Number of block - Treat = 3 levels variables; RTG: plot with existing above-and below-ground biomass removed; RTC: intact vegetation plots, RTS: Seedrain screening / exclusion plots (not used in this paper) ---------- **Description of R scripts** ---------- *recruitment models.r:* This R script was used to fit models investigating biotic and climatic effects on seedling emergence, survival, and establishments. For each life stages, abundances, vital rates, and species diversity were investigated. This script requires the tables “recr.csv”, “site_meta” and “seedrain”. ---------- *time2est.r:* This R script was used to fit models investigating biotic and climatic effects on growth rate (indicated by the time to achieve establishment after emergence). This script requires the table “Time2est.csv” . ---------- **References:** - Berge A. 2010. Seedbank, Seedrain and Seedling Recruitment along Climate Gradients in Southern Norway.
