Data and reproducible analysis files from: Latitudinal clines in floral display associated with adaptive evolution during a biological invasion

Premise: Flowering phenology strongly influences reproductive success in plants. Days to first flower is easy to quantify and widely used to characterize phenology, but reproductive fitness depends on the full schedule of flower production over time. 
Methods: We examined floral display traits associated with rapid adaptive evolution and range expansion among thirteen populations of Lythrum salicaria, sampled along a 10-degree latitudinal gradient in eastern North America. We grew these collections in a common garden field experiment at a mid-latitude site and quantified variation in flowering schedule shape using Principal Coordinates Analysis (PCoA) and quantitative metrics analogous to central moments of probability distributions (i.e., mean, variance, skew, and kurtosis).
Key Results:  Consistent with earlier evidence for adaptation to shorter growing seasons, we found that populations from higher latitudes had earlier start and mean flowering day, on average, when compared to popul..., , , # Data and analysis files from: Latitudinal clines in floral display associated with adaptive evolution during a biological invasion
