abstract：:The terminal allocation and senescence hypotheses make opposite predictions about how age-specific reproductive effort should vary during old age. There is empirical support for both hypotheses, although reports on senescence are more numerous. Individual heterogeneity and selective mortality, however, decrease our ab...
