Abstract

The dwarf stonebasher sibling species Pollimyrus castelnaui and P. marianne use differences in the electric organ discharges (EODs) for species recognition. As EOD waveforms are affected by water conductivity changes, the reliability of species recognition might be impeded due to natural variability in the environment. EODs of P. castelnaui (N = 8) and P. marianne (N = 8) under high (250 mu S/cm) ...
