male courtship song and female preference variation between phylogeographically distinct populations of drosophila montana. | understanding the variation within and between populations in important male mating traits and female preferences is crucial to theories concerning the origin of sexual isolation by coevolution or other processes. there have been surprisingly few studies on the extent of variation and covariation within and between populations, especially where the evolutionary relationships between populations are understood. here we examine variation in female preferences and a sexually selected male song trai ... | 2007 | 17542854 |
