SYNOPSIS. Laboratory selection for desiccation resistance, which has been imposed on five replicate pop-ulations of Drosophila melanogaster for.200 generations, has resulted in enhanced survivability during periods of extreme water stress. The ability of these populations to persistently resist the fatal effects of desiccation is correlated with evolved physiological traits, namely preferential storage of carbohydrates (associated with reduced lipid reserves) and a dramatic increase in blood volume, which has led to a sig-nificant increase in extracellular sodium and chloride content, as well as body mass. When compared to other populations of this drosophilid species, these adaptive traits are unique. While some may argue against the value...
