Developmental isolation and subsequent adult behavior ofDrosophila paulistorum. I. Survey of the six semispecies
We present results deriving from the inception of an investigation (involving 4,000 scored matings) into the development of discriminatory behavior inDrosophila paulistorum. We examined two complementary situatio...
