This dataset contains the raw and derived data used to analyse pollen transfer, pollen deposition, reproductive-organ arrangement, seed production, ovule number, and pollinator activity in Fritillaria persica populations sampled in Israel in 2022. The workbook includes data from two study populations, Arad and Rosh, and is organized into seven worksheets corresponding to different components of the study.
Worksheet descriptions
1. pollen_marked
This sheet contains data from the quantum dot (QD) pollen-labelling experiment used to trace pollen transfer within and between inflorescences. Each row corresponds to a sampled stigma from a plant included in the marked-pollen experiment. Columns include study site (loc), plant number (plant_no), flower position within the inflorescence (position), and the QD colour assigned to the focal donor flower (QD). Separate columns for each emission wavelength (450, 530, 550, 560, 590, 610, 650 nm) record the number of labelled pollen grains detected on the stigma. Additional columns summarize pollen categories: own (self pollen from the focal flower), not_marked_pollen (unlabelled pollen), marked_other_pollen (sum of labelled pollen from other donors), and total_pollen (total pollen grains counted on the stigma). This sheet is the main dataset for distinguishing self, geitonogamous, and cross pollen deposition.
2. pollen_not_marked
This sheet contains pollen counts from open-pollinated flowers that were not included in the QD-labelling experiment. It provides a baseline measure of natural pollen deposition under field conditions. Columns include site (loc), plant number (plant_no), flower number (flower_no), and total pollen grains counted on the stigma (pollen).
3. pollen_marked_control
This sheet contains data from bagged flowers used to assess spontaneous self-pollen deposition in the absence of pollinator visitation. Each row represents one flower. Columns include site (loc), flower number (flower_no), and pollen grains counted on the stigma (pollen). These data serve as a control for autonomous pollen deposition.
4. deposition
This sheet contains measurements of floral morphology and pollen deposition used to examine relationships between reproductive-organ arrangement and stigma pollen load. Each row corresponds to one flower. Columns include site (loc), plant number (plant_no), flower number (flower_no), flower diameter (diameter), lengths of the six anthers (ant_1 to ant_6), style length (style), total pollen grains on the stigma (pollen), and derived variables describing stigma–anther relationships (sty_l_ant, sty_s_ant, longest, shortest). This sheet is used to analyse how herkogamy and flower position relate to pollen deposition.
5. seeds
This sheet contains data on seed production per flower, linked to floral morphology. Columns include site (loc), plant identifier (plant_no), flower number (flower_no), style length (style), mean anther length (anther_mean [mm]), and the number of seeds produced (seeds). The dataset was used to analyse realised female reproductive success in relation to flower position and reproductive-organ traits.
6. pollinaotrs
This sheet contains pollinator observation data. The sheet name includes the original spelling used in the workbook. Columns include site (loc), pollinator group (group), time spent on a flower (time on the flower), number of flowers visited during a foraging bout (flowers_visited), and number of visits recorded in a single observation (visits_per one record). The data summarize pollinator activity and foraging behaviour at the two study sites.
7. ovules
This sheet contains ovule counts used to estimate female reproductive potential along the inflorescence. Columns include site (loc), inflorescence level (level; e.g. bottom, middle, top), plant number (plant_no), and number of ovules per flower (ovules). These data were used to assess position-dependent variation in ovule availability.
