Data from: The strength of sex-specific selection in the wild

Anisogamy predisposes the sexes to very different patterns of selection on
shared traits. Selective differences between the sexes may manifest as
changes in the direction or strength of selection acting on shared
phenotypes. Although previous studies have found evidence for widespread
differences in the direction of selection between the sexes, surprisingly
little is known regarding potential differences in the magnitude of
selection and whether such differences might be confined to specific
components of fitness. We conducted a meta-analysis using 865 estimates of
phenotypic selection from wild populations to characterize sex differences
in the strength of selection and to ask whether different components of
fitness exhibit differences in sex bias in the strength of selection.
Overall, consistent with past results, we find evidence of male bias in
the strength of selection, driven primarily by components of fitness
related to mating success and we discuss several evolutionary
implications.
