Va = ( λ a / l a ) λ x l x m x Another way to think of this is the age distribution of test tubes in a lab: more new one than old ones, associated with ageing is a finite probability of being broken, thus a smaller proportion of all test tubes in the lab will be veery old. These old one will not contribute much to "next generation" Two points: 1) reproductive value may increase from birth to first reproduction (in species that delay reproduction) because as one survives to this age, one increases the probability that one will actually reproduce; 2) the drop in reproductive value with age can account for the evolution of senescence
