Published: 29 September 2023
...Jennifer M. Clark; Allen G. Gibbs ABSTRACT Previous studies have shown that selection for starvation resistance in Drosophila melanogaster results in delayed eclosion and increased adult fat stores. It is assumed that these traits are caused by the starvation selection pressure, but its mechanism...
