Average site values

This file contains average values (SD) for each of the 33 sites used in the study. The variables are latitude, longitude, elevation, tarsus length, wing length, body mass, sperm head length, sperm midpiece length, sperm tail length, sperm total length, CVbm, WW1 allele frequency, WW2 allele frequency, and length of the Clock gene

Rowe et al. sperm morphology data

Data on sperm morphology (i.e. sperm length) for males used in the comparative study of sperm evolutionary rate

Pyrrhula pyrrhula sperm motility

Motility measures of individual sperm tracks analysed by Computer Assisted Sperm Ananlysis (CASA). The file lists the sperm tracks from 11 male Eurasian bullfinches (P. pyrrhula) with details of sampling locality and date. (Raw data file for Table 2 in the paper

Measurements of individual spermatozoa in Azores and Eurasian bullfinches

Measurements of head and flagellum length in 10 spermatozoa per male in 11 Azores bullfinches (P. murina) and 13 Eurasian bullfinches (P. pyrrhula) with details of sampling locality and date. (Raw data file for Table 1 in the paper

Structure input data (Libyan set)

Structure input data (Libyan set

Spatially interpolated predicted 0.1 northern-allele frequency contours for the locus WW1 from the GAM logistic regression geographic model overlaid on elevation background.

<p>The 0.5 isocline represents the center of the cline. The background represents a hill-shade digital elevation model (DEM). The map has a 30 arc-second resolutions and is projected using the Swedish RT 90 0 gon Mercator projection.</p

Sperm measurements (morphology and velocity) of two Passer species

Included in this data set are three .csv files containing data, one .xlsx file with information on the naming of columns in the data files (information for each data file is in a separate tab in the .xlsx file), and R code. However, this R script should be sufficient to understand exactly how analyses were performed. Justification for analysis decisions is indicated in the manuscript

Relationship between sperm length and two sexually selected traits in pied flycatchers.

<p>The figure illustrates the lack of associations between a male's average sperm length and his (A) dorsal plumage coloration (black dots (N = 32): Oslo, Norway, grey dots (N = 34): Røros, Norway, open dots (N = 14): Lingen, Germany) and (B) arrival date (Oslo, Norway). Plumage colour scores refer to the 7-point ‘Drost’ scale <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0032611#pone.0032611-Rskaft1" target="_blank">[23]</a> for the amount of brown versus black in the dorsal plumage, where 1 = jet black, 4 = equal amounts of black and brown, and 7 = pure brown.</p

Sperm velocity as a function of sperm length in pied flycatchers.

<p>The figure shows the relationship between sperm length and (A) sperm velocity recorded 1 min after ejaculate sampling (<i>N</i> = 19, <i>r</i> = 0.06, <i>p</i> = 0.82), (B) sperm velocity recorded after 10 min (<i>N</i> = 11, <i>r</i> = −0.50, <i>p</i> = 0.12), and (C) relative change in sperm velocity from 1 to 10 min after sampling (<i>N</i> = 11, <i>r</i> = −0.79, <i>p</i> = 0.004). All data from the Røros population, Norway. Note that sample size is smaller than for sperm length (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0032611#pone-0032611-g001" target="_blank">Fig. 1</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0032611#pone-0032611-t001" target="_blank">Table 1</a>) because some ejaculates contained too much noise particles (faeces) for motility analysis.</p
