WebSuch phenotypic trade-offs have been suggested to reflect evolutionary constraints. We test this idea by asking whether the selection responses of laboratory populations of Drosophila melanogaster can be predicted from a trade-off between fecundity and starvation resistance revealed by manipulating levels of dietary yeast. Fecundity and ... WebThe concept of phenotypic trade-offs is a central element in evolutionary theory. In general, phenotypic models assume a fixed trade-off function, whereas quantitative genetic theory predicts that the trade-off function will change as a result of selection.

WebApr 10, 2024 · The predator cue effect on processes related to reproduction likely arose due to trade-offs between predator avoidance strategies and other vital functions, such as foraging [59, 60], as reported in other arthropods [61, 62]. These trade-offs are more likely to occur under chronic stress (the case in our study) than under acute stress [59, 61].

Phenotypic trade off

WebInducible defense is a common form of phenotypic plasticity, and inducibility (change in defense after herbivore attack) has long been predicted to trade off with constitutive (or baseline) defense to manage resource allocation. Although such trade-offs likely constrain evolution within species, the extent to which they influence divergence ... WebAlthough there are well-established phenotypic trade-offs associated with wing dimorphism in female insects, there only exist two studies that have established a genetic basis to these trade-offs. The present study provides the first evidence for a genetically based trade-off in male insects, specifically in the sand cricket Gryllus firmus.
