Researchers claim this is the first study to show a link between smarts and mating success in any species.
This information has important implications for optimizing family production in selective breeding programs, conserving sperm from superior pedigree in genome banks, maximizing the use of available gametes in hatchery or research facilities, and understanding mating success in the wild.
Furthermore, graded reduction of the grasping traits resulted in a graded reduction of mating success in males, thus demonstrating both selection for elaboration of the traits and the role of dll in their evolution.
Territorial success contributes to mating success in Drosophila melanogaster [18].
There are other patterns of mating success in our lines that show no relation with aggression.
The major determinant of male mating success in T. commodus is the long-distance advertisement call [34], [35].
These characteristics along with a large investment in vocal display are crucial in determining access to females and in turn mating success in fallow deer [7], [34].
The covering of these scales with nail polish muffled the sounds and significantly reduced mating success in O. nubilalis, showing the importance of ultrasound signaling in mating.
While in the selected Agg line territorial success is a good predictor of male mating success, in one of the least aggressive lines, Winters 23, there is an inverse relation between mating success and territorial success.
We measured the genetically determined outcomes of aggressive interactions, and the resulting effects on mating success, in a panel of diverse inbred lines representing both natural variation and artificially selected genotypes.
However, the presence of two virgin females or that of lures releasing the sex pheromone blend of the male's strain both failed to increase the mating success in inter-strain pairs (Table 1).
