Maternal fecundity was another major theme.
To evaluate the association between maternal fecundity factors and time to pregnancy and risk of asthma in offspring.
In our model, the maternal fecundity loss s = 0.1, and the maternal-effect mortality t0 = 1 are fixed.
The maternal level of PFOA or PFOS was found associated with various reproductive and child health outcomes [ 24, 26- 29], and seems to impact maternal fecundity [ 27].
Maternal flight treatment influenced maternal reproductive output and this study is the first to demonstrate that increased flight during the oviposition period can reduce both maternal fecundity and the quality or composition of eggs.
Consistent with our results using flies, the effects of human p53 and p53-interacting genes such as MDM2 on cancer incidence and longevity are often sex-biased [ 48], and p53 has recently been implicated in regulating mammalian maternal fecundity [ 49].
Also It was shown contributing of microorganisms, increasing maternal age, greater fecundity among people with higher adiposity, sleep debt, endocrine disruptors, pharmaceutical iatrogenesis, reduction in variability of ambient temperatures and intrauterine effects to the obesity [ 26, 27].
We examined twenty different phenotypic traits in both males and females, encompassing vital rates (survival and fecundity), maternal reproductive performance (offspring birth weight, birth date and survival), male rutting behaviour, home range measures, parasite burdens, and body mass.
For three decades 19855 to present day), individuals in the population have been marked and followed from birth to death, with regular re-capture of individuals, producing a wealth of information on age-specific survival, fecundity, maternal reproductive performance, male reproductive behaviour, infection with parasites, ranging behaviour, and morphology (Clutton-Brock and Pemberton, 2004).
Although it is difficult to quantify the relative net fertility outcomes of early vs. late chemotherapy in this context, it is certainly arguable that the fetus of a pregnant breast cancer patient may be, if anything, more precious to the mother than the average pregnancy, given the uncertain prognoses for both maternal survival and fecundity.
The number of hybrid seeds formed depends on the outcrossing rate, the reproductive densities of the parental species, the fecundity of the maternal species and the fecundity of hybrids itself (Hooftman et al., 2007).
