Inbreeding is reputed to distort sex-ratios by reducing the proportion of the homogametic sex. However, many data sets do not show such an effect, and there is a known selective publication bias. To resolve the issue, we (a) developed detailed theoretical expectations for the effects of inbreeding on sex-ratios for autosomal and sex-linked loci with sex-limited effects or with equal effects in the...
Direct estimates of extinction risk are frequently unavailable, so surrogate indicators are used in threatened species categorizations, but there is inadequate information on which best predict vulnerability. We compared the ability of 16 frequently-used factors to predict extinction risk for 45 vertebrate taxa. Median times to extinction were estimated using taxon-specific stochastic population models...
