A series of laboratory selection experiments on Drosophila melanogaster over the past two
decades has provided insights into the specifics of life-history tradeoffs in the species and …

Many latitudinal clines exist in Drosophila melanogaster: in adult body size, in allele
frequency at allozyme loci, and in frequencies of common cosmopolitan inversions. The …

Theory predicts that intralocus sexual conflict can constrain the evolution of sexual
dimorphism, preventing each sex from independently maximizing its fitness. To test this idea …

Clines for size and stress resistance traits have been described for several Drosophila
species and replicable clines across different species may indicate climatic selection. Here …

Studies on selection for faster development in Drosophila have typically focused on the
trade‐offs among development time, adult weight, and adult life span. Relatively less …

Under normal physiological conditions, the mammalian brain contains very little glycogen,
most of which is stored in astrocytes. However, the aging brain and the subareas of the brain …

Longevity extension in Drosophila melanogaster by feeding diet supplemented with
chemicals throughout adulthood can cause harmful side effects. We tested the effect of larval …

Adaptive developmental plasticity allows individuals to match their phenotype with their
environment, increasing fitness where threats are inconsistently present. However, despite …

1. Life history theory generally predicts a trade-off between short juvenile development and
large adult size, assuming invariant growth rates within species. This pivotal assumption has …

Metamorphosis is thought to provide an adaptive decoupling between traits specialized for
each life‐history stage in species with complex life cycles. However, an increasing number …
