If a mother's nutritional status predicts the nutritional environment of the offspring, it would be
adaptive for mothers experiencing nutritional stress to prime their offspring for a better …

Drosophila melanogaster is used extensively for studies of life-history trade-offs involving
acquisition and allocation of nutritional resources. Yet we know very little about the effects of …

Many animal species face periods of chronic nutritional stress during which the individuals
must continue to develop, grow, and/or reproduce despite low quantity or quality of food …

Environmental conditions experienced by parents are increasingly recognized to affect
offspring performance. We set out to investigate the effect of parental larval diet on offspring …

Animals, from insects to humans, select foods to regulate their acquisition of key nutrients in
amounts and balances that maximise fitness. In species in which the nutrition of juveniles …

Background The Y model of resource allocation predicts a tradeoff between reproduction
and survival. Environmental stress could affect a tradeoff between reproduction and survival …

Ancestral environmental conditions can impact descendant phenotypes through a variety of
epigenetic mechanisms. Previous studies on transgenerational effects in Drosophila …

Background The adaptive significance of phenotypic changes elicited by environmental
conditions experienced early in life has long attracted attention in evolutionary biology. In …

We used a novel approach to study the effects of egg size on offspring fitness components in
Drosophila melanogaster. Populations that differed genetically in egg size were crossed …

Insulin plays a major role in connecting nutrient availability to energy homeostasis by
regulating metabolic pathways. Defects in insulin signalling is the primary cause for …
