Non-genetic benefits of mate choice: fecundity enhancement and sexy sons
Article Abstract:
The paternal factors influencing the lifetime fecundity of female stink bugs, Nezara viridula, were investigated by comparing the fecundities and progenies of females that mated with inexperienced males, rejected males and previously mated males. Results indicate that female fecundity is correlated to male antenna length which is associated with the male's ability to deposit nutritive sperms from the paired harlequin lobes of the testes. Non-genetic paternal contributions decline with repeated matings.

Sexual incompatibility and geographical variation in mate recognition systems: tests in the salamander Desmognathus ochrophaeus
Article Abstract:
North American mountain dusky salamanders, Desmognathus ochrophaeus, belonging to geographically isolated populations show sexual incompatibility due to differences in their mate recognition systems. The salamanders take part in assortative mating which is specific to their own population. Salamanders from different populations fail to recognize themselves as mating partners. The differences in the mate recognition systems of isolated populations is mainly qualitative.
