Spatiotemporal variation in selection on floral traits related to abortion rate, predispersal seed predation, and fitness variance

Spatiotemporal variation in phenotypic selection is important for understanding the potential consequences of selection. Variable selection on floral traits is common, yet connecting the variation to potential drivers of selection is less so. Here, we estimated selection on six floral traits of Penstemon digitalis for four populations, with two over four years. We also tested whether an extreme year (2012) with an early spring affected selection on floral traits. For traits that showed evidence of spatiotemporal variation (three), we asked whether variation was related to three aspects of their ecology: flower/fruit abortion, predispersal seed predation and/or opportunity for selection. Attached data includes phenotypic fitness measures used in the main analyses for the paper.

## Description of the data and file structure

Phenotypic traits and fitness measures were done in four populations of *Penstemon digitalis* (BB, NR TH, WF) in 1-4 years.

### Files and variables

Single file with all data \"PhenoData.dryad.csv\". Missing values are left blank.

year = collection year

population = one of four values, see publication for location details

gape.width = width of floral tube opening (mm)

petal.width = width of centre lower petal at widest point (mm)

constriction. width = width of the constriction of floral tube near nectary at the narrowest point (mm) (not included in publication)

tube.length = length of floral tube (mm)

lines = number of purple lines in the corolla tube

colour = intensity of colour based on a 4 point ordinal scale (0 = no lines, 1 = light, 2 = medium, 3 = dark)

pigment = lines*colour (estimate used in paper)

height = total plant height measured at end o...,
