Supplement 1. Cheatgrass demographic data and the R code to perform analyses.

File List seedData.csv (MD5: 1046a13d7dc78e8de7ff15ed1569c743) es.csv (MD5: 83f92d3db02c919782c024c23f02476c) analyses.r (MD5: c2975e34a5540cf99e285a98d83bf817) Description This supplement provides the data and the R code to perform the analyses described in the methods section. The data is contained in seedData.csv and es.csv. The file seedData.csv contains data on seed production, es.csv contains data on emergence and survival. analyses.r is the code to perform analyses. For clarity, we divided the code in five sections: (1) models of seed production in unplanted quadrats; (2) create complete demographic data sets; (3) lambda models; (4) vital rates models; (6) LTRE analyses. In the first section, we use data from seedData.csv to create treatment specific means of seed production in unplanted quadrats. In the second section, we subtract these means to the seed production of planted quadrats. We use the resulting data set in sections three, four, and five to fit the mixed-effect models and to perform the LTRE analyses. Here we present the number, name and description of each column in the two data frames, seedData.csv and es.csv. Metadata seedData.csv 1.Plot Definition: Number identifying each experimental plots. 2. RemovalDefinition: A letter indicating whether the plot was subjected to vegetation removal ("R") or not ("N"). 3. WarmingDefinition: A letter indicating whether the plot was subjected to warming ("W") or not ("C"). 4. EcotypeDefinition: A word indicating whether the quadrat was planted with cheatgrass seeds collected at low ("low"), mid ("mid") or ("high") elevations. Moreover, every plot also contains a quadrat that has not been planted ("unplanted"). 5.
