Clinal variation in developmental time and viability, and the response to thermal treatments in two species of Drosophila

Mostrar todas las versiones(3)

The present study first addressed the question of whether developmental time (DT) and viability (VT) vary clinally along latitudinal and altitudinal gradients in Drosophila buzzatii, an autochthonous specialist and the generalist invasive Drosophila melanogaster. Coincident and positive altitudinal...
