Inheritance of Dorsal Fin Coloration in the Metriaclima Species Complex (Teleostei: Cichlidae) of Lake Malawi
The rock-dwelling cichlids (mbuna) of Lake Malawi have undergone an explosive evolution, giving rise to an assemblage of 300-500 species within the last one million years. Most widespread mbuna 'species' are characterized by the presence of local endemic populations, differing primarily in …

Effects of interspecific competition, salinity, and hurricanes on the success of an invasive fish, the Rio Grande cichlid (Herichthys cyanoguttatus)
The Rio Grande cichlid (Herichthys cyanoguttatus) has been established in the Greater New Orleans Metropolitan Area (GNOMA) for at least 20 years. It is often the most common fish species in urban canals and has also been found in natural waterways outside of the GNOMA. The effects and potential …

Material and Acoustic Properties of Swimbladders of Tilapia and Channel Catfish
Acoustically, teleost swimbladders have been considered resonant underwater bubbles. Contrary results indicating that bladders are tuned less sharply than such a bubble have been explained by damping of surrounding fish tissue. Recent findings in toadfish and weakfish, however, suggest that the …
