Fitness data for experimental populations

Seeds were planted into 5 sites at different geographic range locations: the range interior (CERA), western edge (RNHA), northern edge (SCRS), beyond western edge (CPBS), beyond northern edge (ACNW). Because of poor germination, likely due to drought conditions in spring 2009, the first 5 blocks of the SCRS site were replanted in June and thus are included as a sixth site, SCRSb. Five plant seed source populations were used: Missouri (TYS), Kansas (KZA), Illinois (GRE), Iowa (CRA) and Minnesota (GCD). Eighty seeds at the interior and edge sites, and forty seeds at they beyond edge sites were planted into 10 blocks at each site. Within each block, 4 seeds from the same population were planted into experimental patches, with seeds located 20cm from each other in each patch, and a meter between patches. The patches were randomly assigned to either natural competition (competition) or reduced competition by neighbor removal (removal). Early-season survival, reproductive stage, plant height and leaf number at the middle of the season, and reproductive stage, height, and seed pod number were recorded. In early summer 2010, I returned to each site and recorded the number of seedlings recruiting into the 1 meter area surrounding each experimental patch (separate data file = CfE3_recruitment.csv). | DATA | id: plant identifier | site: site (see above) | block: block, 1-10 at each site | patch: patch within block. 1-20 at interior and edge sites, 1-10 at beyond edge sites | p.pos: position of seed within patch (4 positions, see Fig 1 in paper). | pop: seed source population (see above) | fam: seed source family within population. | esurv: early-season survival (0 - dead/not present, 1 - alive) | july.stage: life-history stage in July: 0 - dead/not present, 1 - vegetative, 2 - flowering, 3 - flower and pods, 4 - pods, 5 - completely senesced | july.height: height (cm) in July | july.leaf, leaf number in July | herbivory.category: percent category of leaf herbivory in July. 1: 0%, 2: 1-25%, 3: 26-75%, 4: 76-100% | For plants with <20 leaves, this was determined either by counting the number of leaves with herbivory, dividing by total leaves and placing in category. For plants with >20 leaves, the % category was visually estimated. | disease.category: percent category for disease in July. values same as herbivory | fall.stage: life-history stage at time of fall measurements, same as july.stage | branch.number: branch number at end of season | seed.pods: number of pods (counting pedicels where pods had broken off) | browsed: whether a plant was browsed. 0-not browsed, 1-plant browsed at some point in season (integrates across observation of browsing in July or at end-of-season) | The attached ReadMe file is the R script (R Project for Statistical Computing) that can be used to recreate the analysis performed in the paper.
