Cloacal gland morphology has been examined extensively (Sever, 1991a, b; 1992a d).
Although it is recognized that cloacal glands exist in some anuran taxa (Van Dijk, 1959), we followed Sever's (1991a) hypothesis that these glands are probably not homologous with those of salamanders.
In terms of cloacal glands, the pleisiomorphic characteristic for salamanders was recovered as lacking cloacal glands for every gland complex (characters 10, 11, 12, 13, 14, and 14, states 0).
The presence of cloacal glands and, thus, the capability of internal fertilization, have long been thought to unite salamanders of the Salamandroidea (e.
In this study, we investigated the residues of fluoroquinolone drugs (ciprofloxacin and pefloxacin) in the cloacal gland
(a site of foam synthesis) and other tissues, such as breast muscle, testes, brain, kidney, and plasma.
The width (lateral) and height (dorsoventral) of the cloacal gland were measured to the nearest 0.
Cloacal gland (CG) is a determinant of sexual activity rate in male quails (Wilson, 1972).
Photoperiod-induced changes in cloacal gland physiology and testes weight in male japanese quail selected for divergent adrenocortical responsiveness.
