This file explains all of the variables in each of the datasets that accompany: Rosengrave P, Montgomerie R 2015ms. Cryptic female choice enhances fertilization success and embryo survival in chinook salmon dataset: Trials.csv year = either 2010 or 2011 ofcon = concentration of OF: 50 in 2010 and 100 in 2011 female = female ID number maleA = male A ID no. where male A is the male with the highest number of eggs fertilized (winner) maleB = male B ID no. Hfemale = heterozygosity of the female, calc from 9 loci HmaleA = heterozygosity of male A calc from 9 loci HmaleB = heterozogisity of male B calc from 9 loci diffHmales = HmaleA - HmaleB Atrioml = male A relatedness (TrioML) value to the female Btrioml = male B relatedenss (TrioML) alue to the female etc diffTRIOML = difference in relatedness values from (Atrioml - Btrioml)  VAPmaleAof = VAP of male A in the OF (ofcon) in µm.s-1 VAPmaleBof = VAP of male B in the OF (ofcon) in µm.s-1 diffVAPof = VAP for male A – VAP for male B VAPmaleAwater = VAP of male A in water (µm/s) VAPmaleBwater = VAP of male B in water (µm/s) diffVAPwater = difference in VAPs of male A and B (VAPmaleAwater - VAPmaleBwater) lengthMaleA = total (fork) length of male A in cm lengthMaleB = total (fork) length of male B in cm diffLENGTH = difference in lengths of male A and B (lengthMaleA -lengthMaleB) fertmaleA = total no. of eggs fertilized by male A (pooled two replicates) fertmaleB = total no. of eggs fertilized by male B (pooled two replicates) diffFERT = fertmaleA - fertmaleB PfertmaleA = total no. of eggs fertilized by male A (pooled two replicates)/ total eggs TOTALfert = total eggs fertilized by male A (pooled) + total eggs fertilized by male B (pooled) dataset: Replicates.csv female = female ID FEMtrial = trial number (replicated) for that female with the same two males maleA = identity of male A maleB = identity of maleB FERTmaleA = number of eggs fertilized by male A FERTmaleB = number of eggs fertilized by male B PFERTmaleA = proportion of eggs fertilized by male A dataset: TRIOML.csv year = year of study female = female ID maleA = male ID Atrioml = relatedness as estimated by TRIOML dataset: Esurvival.csv female = female ID male = male ID TRIOML = male's TrioML relatedness to the female eggs = number of eggs Elive = embryos alive 28 d after fertilization Edead = embryos dead by 28 d after fertilization Psurv = proportion of embryos that surviuved to 28 d VAPof = mean VAP in µm/s over all trials of this male's sperm in this females ovarian fluid ofcon = ovarian fluid concentration: 50% in 2010, 100% in 2011 Hfemale = heterozygosity of the female, calc from 9 loci Hmale = heterozygosity of the male, calc from 9 loci VAPwater = mean VAP in µm/s over all trials of this male's sperm in raceway water dataset: Replicates2 (same data as Replicates.csv but rearranged for loglinear analysis) FemaleID = female ID femtrial = first or second trial with same triad of female and 2 males maleID = male ID fert = number of eggs fertilized rep = first or second replicate with same triad of female and 2 males male = male A or B in that trial
