Additional file 4: of Evolution of female promiscuity in Passerides songbirds

Data set of 24 species with sperm length CV and proportion of EPY from the same study population. These data were used to calculate the linear regression in Fig. 1. (DOCX 18 kb

Additional file 3: of Evolution of female promiscuity in Passerides songbirds

Data set for 202 species used in the comparative analyses. The second worksheet lists the references for paternity studies. The third sheet calculates the sperm length CV and the proportion of EPY from total sperm length data. The fourth sheet gives accession numbers in the Avian Sperm Collection in the Natural History Museum in Oslo, and total sperm length for all sperm samples used in the calculation of sperm length CV, except for two species: Troglodytes aedon (Becky Cramer, pers. comm.) and Notiomystis cincta. (Helen Taylor, pers. comm.). For samples from India (Horornis fortipes, Larvivora brunnea, Passer rutilans and Phylloscopus occipitalis) accession numbers refer to digital photos, as no samples were exported. (XLSX 170 kb
