...Brian P. Schmidt; Jeffrey M. Knowles; Andrea Megela Simmons SUMMARY Current flow is an important biological stimulus for larval anuran amphibians, but little is known about how it is perceived. We quantified behavioral responses to controlled water flow in the bullfrog tadpole ( Rana catesbeiana...

...Y. L. Werner; J. Pylka; H. Schneider; M. Seifan; W. Walkowiak; U. Werner-Reiss SUMMARY The dimorphic ear of the bullfrog, Rana catesbeiana , has long been enigmatic. The male's tympanic membrane (TM) area approximates twice the area of the female's; however, similar size differences in the area...

.... To address this issue, we used in vitro brainstem preparations of an ectotherm, Rana catesbeiana ,at three developmental stages: pre-metamorphic tadpoles, metamorphic tadpoles and fully mature adult bullfrogs. We first compared the effects of NA bath application (0.02-10 μmol l -1 ) on brainstem preparations...

...Douglas Lee Clark; Susan E. Peters SUMMARY It has been shown in the bullfrog, Rana catesbeiana Shaw 1802,that certain forelimb muscles in males have different contractile properties when compared with females, which may result from adaptation for amplexus. We extended this study to a distantly...
