Life-History Consequences of Adaptation to Larval Nutritional Stress in Drosophila
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. Here, we useExpand

Predatory cannibalism in Drosophila melanogaster larvae.
Hunting live prey is risky and thought to require specialized adaptations. Therefore, observations of predatory cannibalism in otherwise non-carnivorous animals raise questions about its function,Expand

Effects of parental larval diet on egg size and offspring traits in Drosophila
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 betterExpand

Evolution of foraging behaviour in response to chronic malnutrition in Drosophila melanogaster
Chronic exposure to food of low quality may exert conflicting selection pressures on foraging behaviour. On the one hand, more active search behaviour may allow the animal to find patches withExpand

EXPERIMENTAL EVOLUTION SHOWS DROSOPHILA MELANOGASTER RESISTANCE TO A MICROSPORIDIAN PATHOGEN HAS FITNESS COSTS
Most organisms experience strong selection to develop mechanisms to resist or tolerate their pathogens or parasites. Limits to adaptation are set by correlated responses to selection, for exampleExpand

Chronic malnutrition favours smaller critical size for metamorphosis initiation in Drosophila melanogaster
Critical size at which metamorphosis is initiated represents an important checkpoint in insect development. Here, we use experimental evolution in Drosophila melanogaster to test the long‐standingExpand

Gut physiology mediates a trade-off between adaptation to malnutrition and susceptibility to food-borne pathogens.
The animal gut plays a central role in tackling two common ecological challenges, nutrient shortage and food-borne parasites, the former by efficient digestion and nutrient absorption, the latter byExpand

Drosophila melanogaster cloak their eggs with pheromones, which prevents cannibalism
Oviparous animals across many taxa have evolved diverse strategies that deter egg predation, providing valuable tests of how natural selection mitigates direct fitness loss. Communal egg laying inExpand

Adaptation to larval malnutrition does not affect fluctuating asymmetry in Drosophila melanogaster
Both stress during development and response to directional selection were proposed to lead to reduced developmental stability of an organism, commonly measured as fluctuating asymmetry. Here, weExpand

Plastic and evolutionary responses of cell size and number to larval malnutrition in Drosophila melanogaster
Both development and evolution under chronic malnutrition lead to reduced adult size in Drosophila. We studied the contribution of changes in size vs. number of epidermal cells to plastic andExpand
