Reproductive potential predicts longevity of female Mediterranean fruitflies.
Reproduction exacts a price in terms of decreased survival. Our analysis of the interplay between age patterns of fecundity and mortality for individual female medflies (Ceratitis capitata) revealed that individual mortality is associated with the time-dynamics of the egg-laying trajectory. In a sample of 531 medflies, we found that each individual has a characteristic rate of decline in egg la...

متن کاملThe impact of diet switching on resource allocation to reproduction and longevity in Mediterranean fruitflies.
Understanding the factors that determine the allocation and utilization of organism resources may provide an insight into the mechanisms of adaptation, ageing and reproduction. Resource allocation, which is regarded as a method of adaptation, increases fitness and is genetically controlled. Experiments with variable diet feeding of female Mediterranean fruitflies (Ceratitis capitata) demonstrat...
متن کاملMediterranean diet and longevity.
While several investigations have focused on the association between individual foods and nutrients upon the development of chronic diseases, few have examined the role that entire dietary patterns may play in health and disease. A dietary pattern generally considered to have beneficial health effects is that of the Mediterranean diet. In this paper, five cohort studies exploring the associatio...
متن کاملFemale reproductive synchrony predicts skewed paternity across primates
Recent studies have uncovered remarkable variation in paternity within primate groups. To date, however, we lack a general understanding of the factors that drive variation in paternity skew among primate groups and across species. Our study focused on hypotheses from reproductive skew theory involving limited control and the use of paternity "concessions" by investigating how paternity covarie...
