| desiccation resistance in four drosophila species: sex and population effects. | desiccation resistance and body mass were measured in multiple populations of each of four species of drosophila: two desert endemic species (d. nigrospiracula and d. mojavensis), and two with more widespread distributions (d. melanogaster and d. pseudoobscura). while flies from the desert species were more desiccation tolerant, there was, in certain cases, significant variation in desiccation resistance among populations of the same species. a significant difference in desiccation resistance wa ... | 2007 | 18836314 |
