Sex differences in ageing in natural populations of vertebrates.
In many long-lived vertebrates (including humans), adult males have shorter lifespans than adult females, partly as a result of higher annual rates of mortality in males and partly owing to sex differences in the rate of ageing. A probable explanation of the evolution of sex differences in ageing is that, in polygynous species, intense intrasexual competition between males restricts the number ...
متن کاملSex differences in nutrient-dependent reproductive ageing.
Evolutionary theories of aging predict that fitness-related traits, including reproductive performance, will senesce because the strength of selection declines with age. Sexual selection theory predicts, however, that male reproductive performance (especially sexual advertisement) will increase with age. In both bodies of theory, diet should mediate age-dependent changes in reproductive perform...

Sex Determining Mechanisms in Vertebrates
7. 1. Summary Vertebrates have various sex determining mechanisms. These have been broadly classified as either genotypic sex determination (GSD) or environmental sex determination (ESD). This terminology, however, may obscure the fact that mixtures between genotypic and environmental sex determination exist, or that genotypic and environmental sex determination may, in fact, be the extremes of...
