Temporal Aspects Of Calling Behavior In Oyster Toadfish, Opsanus-Tau, Michael L. Fine
Temporal Aspects Of Calling Behavior In Oyster Toadfish, Opsanus-Tau, Michael L. Fine
Biology Publications
The oyster toadfish, Opsanus tau (Linnaeus), produces two calls: an agonistic grunt and a boatwhistle associated with courtship (Fish 1954; Tavolga 1958,1960; Gray and Winn 1961). The boatwhistle is produced only by males on nests (Gray and Winn 1961) and is endogenously driven as well as influenced by calling of surrounding males (Winn 1964, 1967, 1972; Fish 1972). A toadfish, not hearing other males, may still boatwhistle for long periods and attract a female. Although toadfish may be influenced to call by the calling of adjacent males, one would assume the circadian patterning of the boatwhistle to be influenced by …

Protein subunit structure in the nuclear envelope has not been previously described. Covalent crosslinking of polypeptides provides a method for studying the subunit structure of protein-rich systems. In this study, several polypeptide crosslinking methods have been used to determine associations among polypeptides in isolated chicken erythrocyte nuclear envelope. Interchain associations that exist in the isolated membrane were fixed by crosslinking the polypeptides in the isolated nuclear envelope. Crosslinked and uncrosslinked polypeptides were resolved by electrophoresis in a dissociating detergent system. Each agent caused distinctive alterations in the gel pattern. Certain bands diminished and disappeared while new bands of two or …
