Evolution of starvation resistance in Drosophila melanogaster: measurement of direct and correlated responses to artificial selection.

摘要: Laboratory selection for resistance to starvation has been conducted under relatively controlled conditions investigate direct and correlated responses artificial selection. With regard resistance, there are three physiological routes by which the trait can evolve: resource accumulation, energy conservation tolerance. A majority of energetic compounds macromolecules including triglycerides, trehalose other sugars, soluble protein increased in abundance as a result Movement was additionally investigated with selected males moving less than control females exhibiting similar response Results obtained from this study supported two possible evolutionary mechanisms adaptation starvation: compound storage conservation. If is based on an evolutionarily conserved pattern genetic correlations (elevated lipid, elevated sugars reduced movement), then medically relevant architecture should be depth.
