Breeding behavior of the African frog, Chiromantis xerampelina: multiple spawning and polyandry
Article Abstract:
The breeding behavior of the African frog (Chiromantis xerampelina) is investigated. Results show that chorus attendance, rather than male body size, is the best predictor of male mating success. Moreover, one unique breeding feature is the presence of peripheral males that compete with amplexing males for fertilizations. On the other hand, 66 percent of the females are polyandrous, and the main cause of polyandry is the dismounting of amplexing males between nesting sessions.

Costs and benefits of mate choice in the lek-breeding reed frog, Hyperolius marmoratus
Article Abstract:
A study was conducted on female lek-breeding frogs to determine the cost and benefits in choosing their mate. Two direct potential benefits examined were the assurance of fertilization and reduction in search costs. Results showed that the female's mate preference is not based on the level of fertilization because males have relatively similar fertilization rates. Rather, mate choice is attributed to the costs of mate searching due to predation pressure.

Repeatability of mate choice: the effect of size in the African painted reed frog, Hyperolius marmoratus
Article Abstract:
Evaluation of the repeatability of mate choice among female painted reed frogs that are offered a choice between artificial advertisement call varying in frequency shows that female response to stimuli differing in frequency depends on female size. Larger females are affected more by changes in call frequency, with higher probability to express mating preference for low frequency call. Repeatability of mate choice is exhibited by individual females.
