Fruit length in a naturally-pollinated Yucca glauca population

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

IBM code for moth oviposition in response to basal fruits

This R script contains the code for the Individual Based Model in Appendix 2 of the article. The model was developed to support our prediction that with increasing number of basal fruits fewer yucca moth larvae will emerge from distal fruits because of fewer ovipositions in those flowers with increasing number of basal fruits
