title: Flower manipulation experiment with Yucca glauca

description: <b>Description</b><br>This dataset contains processed data for flower retention in response to flower position, presence of basal fruits, and nursery pollinator oviposition from a field experiment using <i>Yucca glauca</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 an inflorescence.<br><br><b><b>Description of column headers</b><br>infl</b> - ID of the inflorescence protected for use in the experiment. All IDs are numeric IDs, except for one that is alphanumeric.<br><b>x</b> - Universal Transverse Mercator (UTM, Zone 14T, datum WGS 84) Easting coordinate of inflorescence<br><b>y</b> - Universal Transverse Mercator (UTM, Zone 14T, datum WGS 84) Northing coordinate of inflorescence<br><b>elev</b> - Elevation above sea level (m) of inflorescence<br><b>ht_cm</b> - Height (cm) of the inflorescence from the point of origin at the base of the rosette to the tip.<br><b>basaldia_mm</b> - Basal diameter (mm) of the inflorescence's rosette (an index of rosette size) measured below the lowest crown of green leaves<br><b>Trose</b> - Total number of rosettes in the visibly-identifiable <i>Yucca glauca</i> clump with the focal inflorescence<br><b>Oinfl</b> - Number of other inflorescences in the visibly-identifiable <i>Yucca glauca</i> clump. If inflorescences existed they were broken before the experiment began.<br><b>buds</b> - Total number of buds/flowers on the inflorescence<br><b>beetles</b> - Number of <i>Carpohilus sp.</i> beetles counted on and removed from the focal inflorescence at the time of protecting the inflorescence with a mesh sleeve.<br><b>aphids</b> - Presence of aphids on the inflorescence at any time during the experiment (binary variable).<br><b>context</b> - The inflorescence treatment assigned to the inflorescence. F refers to basal fruits B refers to buds. One and 0 refer to presence or absence of fruits or buds. There were three inflorescence treatments, (1) 3 basal experimental flowers with buds above (F0B1), (2) 3 distal experimental flowers with no basal fruits and no buds above (F0B0), and (3) 3 distal experimental flowers with 1 to 3 basal fruits and no buds above (F1B0).<br><b>ovi</b> - The artificial oviposition treatment assigned to the inflorescence. There were three treatments, (1) no oviposition treatment where no wounds were applied (Z), (2) low oviposition treatment where 6 wounds were applied (L), and (3) high oviposition treatment where 24 wounds were applied (H).<br><b>Fr</b> - Number of basal fruits on the inflorescence as part of the assigned treatment. Inflorescence treatments F0B1 and F0B0 (see <b>context</b>) had zero basal fruits. The number of basal fruits for inflorescence treatment F1B0 (see <b>context</b>) were recorded.<br><b>B</b> - Number of buds on the inflorescence as part of the assigned treatment. There were no buds for inflorescence treatments F1B0 and F0B0 (see <b>context</b>). The total number of buds above basal flowers in inflorescence treatment F0B1 (see <b>context</b>) were recorded. The number of buds for one of the inflorescence is missing (NA).<br><b>donor</b> - ID of the donor plant that was used to hand-pollinate experimental flowers. Some of these included inflorescences used in the experiment and have the same ID as in <b>infl</b>. Contains both numeric and alphanumeric IDs.<br><b>MD</b> - Date on which the inflorescence was manipulated to obtain the required inflorescence treatment. Manipulations involved removal of flowers and buds, hand-pollination of basal flowers for the F1B0 treatment (see <b>context</b>). Dates are in mm/dd/yyyy format.<br><b>TD</b> - Date on which the artificial oviposition treatment was applied to the experimental flowers and they were hand-pollinated. This was usually later then manipulation date (<b>MD</b>) for the F1B0 treatment (see <b>context</b>) because time was needed basal fruits to be initiated before the oviposition treatment could be applied. Dates are in mm/dd/yyyy format.<br><b>CD</b> - Date on which the inflorescence was checked to determine how many experimental flowers (out of 3 total flowers) were retained i.e. developed into fruits. This was 10 days after the treatment date (<b>TD</b>). Dates are in mm/dd/yyyy format.<br><b>fruitsR</b> - The number of experimental flowers that were retained (out of 3 experimental flowers)<br><b>FD</b> - Date on which fruits were collected for weighing. This was 25 days after the treatment date (<b>TD</b>).<br><b>E1W</b> - The mass of the the first fruit from experimental flowers (g), if any. If no fruits existed, or if the fruit was lost, NA was used.<br><b>E2W</b> - The mass of the second fruit from experimental flowers (g), if any. If no second fruit existed, or if the fruit was lost, NA was used.<br><b>E3W</b> - The mass of the third fruit from experimental flowers (g), if any. If no third fruit existed, or if the third fruit was lost, NA was used.<br><b>avgRFwt</b> - The average mass of fruits from experimental flowers (average of <b>E1W</b>, <b>E2W</b>, and <b>E3W</b>). If only one fruit mass was present, that value was used.<br><br>
