... Bioacoustics Electric communication Abstract. Animal communication in any sensory modality is influenced by environ mental constraints on signal transmission and detection. Acoustic signals are subject to frequency-dependent attenuation, temporal degradation, and masking by environmen­ tal noise...

...Carl D. Hopkins Acoustic and electric communication differ in one important respect: while acoustic communication signals propagate through air or water as a wave, electric signals do not propagate, but exist instead as electrostatic fields. As a result of propagation, acoustic signals...

... that evolutionary convergence in brain anatomy and function is widespread. Although there are relatively few neuroethological studies in which brain and behavior have be studied within an evolutionary framework, three relatively well studied cases are reviewed here: electric communication among gymnotiform...
