ON behalf of Michael Fine let me please inform you about the following article:

Javier S. Tellechea, Walter Norbis, Daniela Olsson and Michael L. Fine (2011): 
Calls of the black drum (Pogonias cromis: Sciaenidae): geographical differences 
in sound production between northern and southern hemisphere populations. J. 
Exp. Zool. 315A (1), 48-55.

Abstract: Because of apparent reproductive isolation between Northern and 
Southern hemisphere populations of the black drum Pogonius cromis, we tested 
the hypothesis that advertisement calls from a southern population would differ 
from known calls of North American populations. Additionally, we quantified 
disturbance and advertisement calls, their changes with fish size and sex, not 
previously examined in this species. Unlike most sciaenids, both sexes of P. 
cromis possess robust sonic muscles, and both produce disturbance calls when 
handled. However, only males produce an advertisement call used in courtship. 
The disturbance call consists of a variable train of short-duration pulses 
(average 23âms). The duration, interpulse interval, and dominant frequency of 
pulses are similar in males and females and change developmentally: pulse 
duration and interpulse interval increase and dominant frequency decreases with 
fish size. Advertisement calls, recorded in the field and in captivity, are 
long-duration (average 184âms) and tonal. Based on variation in fundamental 
frequency, which decreases with fish size, field choruses are composed of 
different-sized individuals. The duration of advertisement calls, about a third 
of those from Florida populations, suggests genetic differentiation between 
northern and southern populations.
