Description Brood (mprop_brood) and helper (mprop_help) sex ratios, expressed as proportions of males, from published studies of cooperatively breeding birds. See references from appendices for full references. See manuscript for criteria used to determine data quality (3 = high, 1 = low). See Table A1 for abbreviations used in helper_effects (UK = ?, these species were excluded from restricted analysis; NP species were excluded from all analyses). Created in Microsoft Excel.

Title effect sizes
Downloaded 2 times
Description Effect sizes used in meta-analysis of sex ratio adjustment in response to a lack of helpers in cooperatively breeding birds. Test statistics used to calculate effect size are provided, except where these were taken directly from a previous publication (detailed in technique column). Magnitude of effect given in effect_size; effect_exp includes positive/negative direction relative to prediction (biased production of helpful sex in response to deficiency of help). Variance is given in v and used to calculate weight (1/v) for calculation of weighted mean. Columns containing max and/or min are the same as for effect_exp but with the effect sizes of unknown direction treated as positive or negative respectively. Overall weighted mean and confidence interval reported in the manuscript.
