- The effects of seasonal hypertrophy and atrophy on fiber morphology, metabolic substrate concentration and sound characteristics of the weakfish sonic muscleM A Connaughton
College of Marine Studies, University of Delaware, Newark 19716, USA
J Exp Biol 200:2449-57. 1997..Seasonal sonic muscle hypertrophy, therefore, functions as a secondary sexual characteristic that maximizes vocalization amplitude during the spawning period...
- Effects of fish size and temperature on weakfish disturbance calls: implications for the mechanism of sound generationM A Connaughton
Washington College, Department of Biology, Chestertown, MD 21620, USA
J Exp Biol 203:1503-12. 2000..We suggest that the lower dominant frequency of larger fish is caused by a longer pulse (=longer muscle twitch) and not by the lower resonant frequency of a larger swimbladder...
- Weakfish sonic muscle: influence of size, temperature and seasonM A Connaughton
Washington College, Department of Biology, 300 Washington Avenue, Chestertown, MD 21620, USA
J Exp Biol 205:2183-8. 2002..This paper demonstrates for the first time that the dominant frequency of a fish sound produced by a single muscle twitch is apparently determined by the velocity of the muscle twitch rather than the natural frequency of the swimbladder...
