Fire & fitness at Staffanson Prairie Preserve

Here are the code and data for the manuscript:

“Burning for a mate: Fire synchronizes flowering and boosts reproduction in a widespread but declining prairie species“

CODE: R script echinacea_sppFireCode.R replicates the data analysis and produces Figures 2, 3, and 4 of the manuscript. The R script reads the csv file below.

DATA: The ascii comma-separated-values file echinacea_sppFireData.csv contains spatial and reproductive measures for burned and unburned mating scenes at Staffanson Prairie Preserve from 1996 to 2016.

Fields include:

unit: “east” or “west” management unit at Staffanson Prairie Preserve (text)
year: year of growing season, 1996 – 2014 (numeric)
flaPlas: count of flowering plants in unit (numeric)
totalPlas: count of total living plants, flowering + nonflowering (numeric)
hdCt: average number of flower heads per flowering plant (numeric)
nn1.hmean; nn2.hmean; nn3.hmean; nn4.hmean: harmonic mean distance to first, second, third or fourth nearest neighbor in meters (numeric)
flw: proportion of plants in flower (numeric)
flwDensity: flowering plants per hectare, count of flowering plants divided by unit area (numeric)
burned: indicates whether unit was burned prior to the growing season, “burned” or “unburned” (text)
meanSdSet: average proportion of achenes which contain fertilized embryos (numeric or NA for non-sampled years)
meanFecundity: average number of fertilized achenes produced per plant, product of individual seed set, achene count, and head count (numeric)
lwr95.sdSet: lower bound of bootstrapped 95% confidence interval for mean seed set (numeric)
upr95.sdSet: upper bound of bootstrapped 95% confidence interval for mean seed set (numeric)
meanAcheneCt: average number of achenes produced per flower head, includes fertilized and unfertilized achenes (numeric)
meanSp1: average number of days styles persist on a flower head (numeric)
lwr95.sp1: lower bound of bootstrapped 95% confidence interval for mean style persistence (numeric)
upr95.sp1: upper bound of bootstrapped 95% confidence interval for mean style persistence (numeric)
mean.sync: average pairwise temporal flowering synchrony, proportion of overlapping flowering days (numeric)
sdsd: standard deviation of flowering start date (numeric)
mean.duration: average flowering duration, in days (numeric)
