Variation in sperm precedence during mating in male flies, Dryomyza anilis
Article Abstract:
A study of the variation in sperm precedence during mating in male flies seeks to show the differences in fertilization success. In the fly Dryomyza anilis, individual variation in sperm precedence has several possible causes because of their unusual mating behaviour, which includes a series of tapping sequences. The study shows large differences between individual males' fertilization success, apparently governed by the number of tapping sequences and female resistance.

Sperm allocation, sperm production and fertilization rates in the bucktooth parrotfish
Article Abstract:
The males and females of spawning bucktooth parrotfish maximize the fertilization rate by allocating sperms and increasing sperm production. The number of sperms released by males increases with an increase in the body size and clutch size. The clutch size increases with increase in female body size. Due to sperm competition with large size females, the males release the minimum number of sperms required to fertilize maximum number of eggs in different clutch sizes.
