J Exp Biol (2022) 225 (7): jeb243917.
Published: 31 March 2022
.... As for electrical fish that display clear spectral jamming avoidance responses (JAR), bats have been reported to mitigate the effects of jamming by shifting the spectral contents of their calls, thereby reducing acoustic interference to improve echo-to-noise ratio (ENR). Here, we tested the hypothesis...

...Bernd Kramer ABSTRACT Eigenmannia’ s, jamming avoidance response (JAR) is a frequency change of its electric organ discharge (EOD) in response to an electric stimulus of similar frequency (small ΔF; ΔF = F Fish – F Stim ). It is assumed that the response to an unclamped stimulus, ΔR = F Response...
