| variability of wing size and shape in three populations of a recent brazilian invader, zaprionus indianus (diptera: drosophilidae), from different habitats. | zaprionus indianus (diptera: drosophilidae) is an african species that was introduced in brazil near the end of the 1990's decade. to evaluate the adaptive potential of morphological traits in natural populations of this recently introduced species, we have investigated wing size and shape variation at rio de janeiro populations only two years after the first record of z. indianus in brazil. significant genetic differences among populations from three distinct ecological habitats were detected. ... | 2005 | 16247699 |
