Title: Impacts of soil nitrogen and phosphorus levels on cytotype performance of the circumboreal herb, Chamerion angustifolium: implications for polyploid establishment Authors: Angela M. Walczyk (amwalczy@mtu.edu), Erika I. Hersch-Green (eherschg@mtu.edu) Year: 2018 *Analyses preformed in JMP Pro 13.0 software package (SAS Institute, Cary, North Carolina, USA): https://www.jmp.com/en_gb/software/predictive-analytics-software.html ----------------------------------------- Datafile: Walczyk & Hersch-Green 2019_AJB_Dryad File_3 Plant ID: Identification of each experimental plant. Letters were used to differentiate plants grown in the same pot. Nut: Either low (LL) or high (HH) nitrogen:phosphorus treatment Comp2: Whether a plant was grown in competition (1=yes, 0=no) Focal Pldy: Focal plant's ploidy level. (2x = diploid, 4x=established tetraploid, 4x' = neotetraploid) Comp pldy: The ploidy level of a competitor plant Geno: Maternal genetic line of a focal plant. Height at Time: The height of each plant (cm) taken at the beginning of the whole plant bioassay Phenology: Phenology of plant at the beginning of the assay on an ordinal scale. 1= basal rosette, 2= elongated stem (no flower buds at all), 3= immature flower buds (small and green color), 4= mature flower buds (pink color), 5= at least one mature flower, 6= more than one mature fruit # Before: The number of leaves on a plant at the start of the whole plant bioassay Total # Dam: The total number of leaves damaged by S. exigua % Total Damage: The percentage of total plant leaf area consumed by S. exigua during the whole plant bioassay. This value was square root transformed in the “SQRT % Total Damage” column 1.-------------------- Statistical Test: ANCOVA for % area consumed by S. Exigua in whole plant bioassay File name: Walczyk & Hersch-Green 2019_AJB_Dryad File_3 Corresponding Tables/Figures: Table 4 Model Factor(s): Focal Pldy, Comp2, Nut, Focal Pldy x Comp2, Focal Pldy x Nut, Comp2 x Nut, Focal Pldy x Comp2 x Nut Covaraite(s): Height at Time Model Response(s): SQRT % Total Damage
