Depending on availability, mothers may thus influence offspring quality by depositing variable amounts of carotenoids into the eggs. Sex allocation theory predicts that in good quality environments, females should invest into offspring of the sex that will provide larger fitness return, generally males...
The Charnov-Bull hypothesis has been widely accepted to explain the adaptive significance of temperature-dependent sex determination (TSD),but empirical support for this hypothesis is still limited. Eggs of the Chinese three-keeled pond turtle (Chinemys reevesii) were incubated at 26 ℃,28℃,and ...
The sex divergence in foraging habits may be amplified by sexual size dimorphism; females grow larger than males, and larger snakes (of both sexes) feed more on damselfish (which often lay their eggs in exposed sites) than on blennies and gobies (whose eggs are hidden within narrow crevices...

The primary outcome measure was endothelial function measured as flow-mediated dilatation. Results Compared with the control breakfast (ie, high-carbohydrate breakfast), daily consumption of eggs showed no adverse effects on flow-mediated dilatation (7.2% ± 2.9% vs 7.5% ± 2.9%, P = .33), ...
Therefore, to understand the molecular mechanisms underlying the development of atherosclerosis, we intervened in ApoE-/- mice maintained on a high-fat diet with Nippostrongylus brasiliensis (N. brasiliensis) infection and immunized wit...
Western societies notice an increasing interest in plant-based eating patterns such as vegetarian and vegan, yet potential effects on the body and brain are a matter of debate. Therefore, we systematically reviewed existing human interventional studies o
of Japanese quail at 14 weeks of age were used with sex ratio 2 female / 1 male to study the effect of maternal body weight, some blood parameters and egg quality traits on fertility% (F%), hatchability% for total and fertile eggs (H/TE % and H/FE %), and chick weight (CW). ...
For once-mated females of Nezara viridula, size (width across the pronotum at the humeral angles) was positively correlated with fecundity (total lifetime egg production), size of the largest egg mass (number of eggs) and longevity (days as adult). Mate size was positively correlated with fe...
(1995) reported that high protein diets (32–40 %) stimulated earlier sexual maturation of Nile tilapia (Oreochromis niloticus) at stage IV development, but a low protein diet (10 %) delayed tilapia oocyte growth and led to few eggs or their chemical composition changes during maturation. ...
