# Title of Dataset:Can diet niche partitioning enhance sexual dimorphism? --- This dataset was produced for meta-analysing published stable isotope values for male and female vertebrates, with the goal of examining associations between size dimorphism and ecological divergence between sexes. The dataset contains information relevant to the papers from which data were extracted, species information (e.g. name, diet), male and female body weights, sample sizes and stable isotope data for each sex. ## Description of the Data and file structure The data is available as csv, containing our raw data, as used for our analyses. Each row contains data for one tissue, from one species, in one study. If multiple tissues were analysed from the same species in the same study, each tissue is contained in a seperate row. If multiple species were analysed in the same study, each species is contained in a seperate row. Data Key: Author: author list for papers from which we extracted data. Year: year of publication of papers from which we extracted data. Title: title of papers from which we extracted data. Taxon: Category to which study species belongs (e.g. "Mammals"). Genus: Genus of study species. Species: Species of study species. Weight_Female: Body mass of females of study species. Weight_Male: Body mass of males of study species. Diet: Dietary class of study species (e.g. "Carnivore"). Gape_Lim: for carnivores only, 'Yes' denotes gape-limited carnivores (fish and snakes), 'No' denotes non-gape-limited carnivores. Tissue_type: The tissue for which stable isotope ratios were analysed in a given study (e.g. "blood"). n_female: Number of female study animals. n_male: Number of male study animals. mean_fem_d15N: mean nitrogen stable isotope ratio of female study animals. sd_fem_d15N: pooled nitrogen stable isotope ratio standard deviation of female study animals. mean_mal_d15N: mean nitrogen stable isotope ratio of male study animals. sd_mal_d15N: pooled nitrogen stable isotope ratio standard deviation of male study animals. mean_fem_d13C: mean carbon stable isotope ratio of female study animals. sd_fem_d13C: pooled carbon stable isotope ratio standard deviation of female study animals. mean_mal_d13C: mean carbonstable isotope ratio of male study animals. sd_mal_d13C: pooled nitrogen stable isotope ratio standard deviation of male study animals. Describe relationship between data files, missing data codes, other abbreviations used. Be as descriptive as possible. Cells equal 'Na' where information was not available or not gathered (e.g. dietary information was not gathered for species whose mass data was unavailable). For example, if stable isotope data for a species was extracted from a study, but body masss diet were unavailable, the isotope data remains present in the dataset, but the male and female mass columns are 'Na'. ## Sharing/access Information Links to other publicly accessible locations of the data: Was data derived from another source? If yes, list source(s): A bibliography of papers from which isotope ratios were taken is available in the main text.
