Frogs<\/h2>\n

Sexual selection studies:<\/strong><\/p>\n

Have you heard frogs calling at night? The males call to attract females. Females may choose a mate without even seeing him!<\/p>\n

Stan Rand studies T\u00fangara Frogs<\/p>\n

Male tungaras produce a “simple call”:<\/p>\n

tun<\/em><\/p>\n

and several “complex” calls:<\/p>\n

tun gara

Stan Rand<\/strong> (staff scientist), records frog sounds.<\/p>\n

Which calls do the females prefer?<\/strong><\/p>\n

Diego Lombeida<\/strong> place a female between two speakers: We play the “simple” call from one speaker and the”complex” call from the other. More females hop toward the complex call.<\/p>\n

Dangerous love songs<\/strong><\/p>\n

This male tungara frog was calling to attract a female. The frog-eating bat found him because of his call. Tungara frogs make complex “sexy” calls and less complex “not so sexy” calls.<\/p>\n

We have shown that female frogs prefer complex calls. To attract females, a male should use the complex call as much as possible.<\/p>\n

Unfortunately it’s easier for a bat to locate a frog making a complex call. Frogs call less, and less romantically, when they can see the bats.<\/p>\n

What makes these males different from these females?<\/strong> The males have characteristics that attract a mate.<\/p>\n
