Phylogenetic comparative analysis of electric communication signals in ghost kn...
Turner, Cameron R.; Derylo, Maksymilian A.; David Santana, C. de; Alves-Gomes, José Antônio; Smith, G. TroyElectrocommunication signals in electric fish are diverse, easily recorded and have well-characterized neural control. Two signal features, the frequency and waveform of the electric organ discharge (EOD), vary widely across species. Modulations of the EOD (i.e. chirps and gradual frequency rises) also function as active communication signals during social interactions, but they have been studied in relatively ...
Chirping and asymmetric jamming avoidance responses in the electric fish Distoc...
Petzold, Jacquelyn M.; Alves-Gomes, José Antônio; Smith, G. TroyElectrosensory systems of weakly electric fish must accommodate competing demands of sensing the environment (electrolocation) and receiving social information (electrocommunication). The jamming avoidance response (JAR) is a behavioral strategy thought to reduce electrosensory interference from conspecific signals close in frequency. We used playback experiments to characterize electric organ discharge frequen...
