Description: This dataset contains processed data for size of fruits from different positions on naturally-pollinated Y. glauca inflorescences, including indices of extent of pollination and oviposition by nursery pollinator Tegeticula yuccasella. Refer to manuscript for details of the study system, study site, and methods. Format The file is in .csv format. Each row contains data for a fruit. Description of column headers stalk - ID of the inflorescence stalk in the patch. Same as infl in dataset for "Flower retention in a naturally-pollinated Y. glauca population" fruits - Number of fruits matured on the inflorescence basaldia - Basal diameter (mm) of rosette (an index of rosette size) measured below the lowest crown of green leaves. buds - The total number of buds/flowers on the inflorescence fruitID - ID of fruit. Same as position of flower (fl) that developed into fruit (fr = 1) in dataset for "Flower retention in a naturally-pollinated Y. glauca population" uniqueID - Combination of inflorescence or stalk ID (stalk) and fruitID to obtain a unique identity for each fruit in the dataset. The format is S followed by the ID in the stalk column and F followed by the ID in the fruitID column length - the length of the fruit (mm) from the base to the tip of the remnant size. Fruit length is an index of fruit size. largest_dia - The diameter of the fruit at the widest point (mm). wt - The mass of air-dried fruit (g). tapering - Whether the base of the fruit is tapered, indicating pollen limitation, or rounded (binary variable). cons - The number of locules with constrictions (out of 6 locules or compartments in the ovary). Damage to multiple ovules during ovipositions results in constrictions. Hence, they are an index of the level of ovipositions. scaled - The scaled position of flower from which fruit was developed. Calculated by dividing the flower position, here fruitID by the number of total buds/flowers in buds. A fruit from the topmost flower will have a position of 1. frbelow - The number of fruits basal to the focal fruit. Yucca glauca flower sequentially from bottom up. So, basal fruits were likely initiated before the focal fruit was initiated. pos - The position of flowers categorized into bottom third (B), middle third (M), and top third (T) flowers. Flowers with scaled positions less than 1/3 were classified as B, greater than 2/3 were classified as T, and the remaining middle flowers were classified as M.
