Abstract

Marcusenius pongolensis (South Africa) and M. altisambesi (Upper Zambezi/Okavango) differ in the sex difference of their electric organ discharges (EODs). It is permanent and graded in the former and seasonally dimorphic in the latter. Four out of six experimental female M. altisambesi gave significantly stronger responses to the long playback EODs of breeding males rather than short EODs, ...
