Contrasting the form and strength of pre- and postcopulatory sexual selection in a flatworm

Sexual traits may be selected during multiple consecutive episodes of selection, occurring before, during, or after copulation. In the research article entitled \"Contrasting the form and strength of pre- and postcopulatory sexual selection in a flatworm\", published in Evolution, we measured pre- and postcopulatory phenotypic traits alongside variation in fitness components at different episodes. Namely, we assessed the mating success, sperm-transfer efficiency, and sperm fertilising efficiency of focal worms in which we measured 13 morphological traits, and performed multivariate selection analyses assessing the form and strength of selection. We archived the datasets and R scripts necessary to reproduce all analyses performed in this paper., Methods fully explained in the paper., , # Files supporting the paper by L.

## Description of the data and file structure

There are overall five files: two .csv files containing the data, and three annotated .R files handling the data files and performing all analyses described in the paper.

1. MultSel_TraitData.csv stores the values of the 13 morphological traits of the 160 focal worms. ba (body area; x 10³ µm²), tt (testis size; x 10³ µm²), oo (ovary size; x 10³ µm²), Dsv (delta seminal vesicle; x 10³ µm²), CS (stylet centroid size), RWS1, 2, and 3 (first, second, and third relative warp score of the stylet), feeler (sperm's feeler length; µm), body (sperm's body length; µm), shaft (sperm's shaft length; µm), brush (sperm's brush length; µm), bristles (sperm's bristles length; µm).
