Chorus size influences on the anti-predator response of a Neotropical frog
Article Abstract:
The effect of the number of males on a lek on anti-predator behavior was examined using male Tungara frogs. These frogs form choruses and call from stationary positions to lure females. The presence of predators results in the shutting down of callingthat may entail costs because females select males in accordance with such calls. In this regard, the difference of duration of non-calling evasive behavior was determined among various sizes of choruses. The results revealed that chorus size influenced calling behavior. The shutdown duration of two-malechoruses was longer than that of solitary males, four-male or five-male choruses.

Proximate costs and benefits of mate acquisition at leks of the frog Ololygon rubra
Article Abstract:
A study of the mating behavior of the lekking frog reveals that female frogs show preference for mates which can defend territories and contribute to female fitness. In small sized males, sperm reserves get depleted before females finish laying eggs, whereas large sized male frogs produce lower frequency calls, leading to lower fertilization rate. Therefore, the female lekking frogs, Ololygon rubra, choose right sized mates to the approximate ratio of 81% of their own snout-vent length.

Mate choice in the neotropical frog, Hyla ebraccata: sexual selection, mate recognition and signal selection
Article Abstract:
A study of the neotropical frogs' mating behavior shows that the frogs can discriminate between hetrospecifics and conspecifics, proving that there is no specific male recognition call and that female responsiveness depends on male choice. Any variation in mating success is a product of sexual selection and response to mating calls by the female frog. Females may even respond to hetrospecific calls of Hyla phlebodes when there are insufficient conspecific mating calls.
