Description of the data and file structure

Original data of Primula tibetica, collected in the common garden of the South-East Tibetan Plateau Station for Integrated Observation and Research of Alpine Environment, Chinese Academy of Sciences. In the common garden, we manipulated the pollination regime (open-pollination vs. supplemental hand-pollination) at three sites that differed in soil water content (low, medium, high) and quantified pollinator- and nonpollinator-mediated selection on four traits (flowering start, flowering duration, number of flowers, corolla size).

In the Excel file, each line represents one individual, with data on phenotypic traits and female fitness. The definition of each column header follows:

• ‘Site’ indicates site in the common garden, with three levels of soil water content (low, medium, and high).
• ‘Quadrat’ indicates one-by-one meter square within site.
• ‘Individual’ indicates plant identity. The letters indicate site, where B, C, and D represent the medium-, high- and low-water sites, respectively. The first number indicates in which quadrant the plant was located, and the second number indicates position within the quadrant. For example, B1-1 represented the number 1 individual in the number 1 quadrat at the medium-water site.
• ‘Pollination treatment’ indicates whether the plant was open-pollinated (C), or supplementally hand-pollinated (HP).
• ‘Morph’ indicates flower morph type of the dimporphic Primula tibetica. S is the short-styled morph, and L is the long-styled morph.
• ‘Flowering start (Julian day)’ and ‘flowering end (Julian day)’ indicates the onset and end of flowering for each individual, defined as the day the first flower opened, and the day the last flower wilted. Measurement unit = day.
• ‘Flowering duration (d)’ indicates the duration of flowering for each individual, and was calculated as (flowering duration = flowering end - flowering start). Measurement unit = day.
• ‘Corolla size’ indicates flower size, and was calculated as the mean of the maximum diameter measured on the first three open flowers on each individual, to the nearest 0.01 mm. Measurement unit = mm.
• ‘Number of flowers’ was the total number of flowers per individual, recorded at the end of the flowering period. Measurement unit = number.
• ‘Number of fruits’ was the toal number of fruits per individual, recorded at fruit maturation. Measurement unit = number.
• ‘Fruit set’ indicates proportional fruit production per individual, calculated by divding number of fruits on number of flowers. Measurement unit = number.
• ‘Number of seeds per plant’ indicates the total seed production per plant. Measurement unit = number.
• ‘Number of seeds per fruit’ indicates the total number of seeds per fruit. Measurement unit = number.
