...Niall Crawford; Thomas Endlein; W. Jon P. Barnes SUMMARY Tree frogs use adhesive toe pads for climbing on a variety of surfaces. They rely on wet adhesion, which is aided by the secretion of mucus. In nature, the pads will undoubtedly get contaminated regularly through usage, but appear to maintain...

...Ingo Scholz; W. Jon P. Barnes; Joanna M. Smith; Werner Baumgartner SUMMARY Knowledge of both surface structure and physical properties such as stiffness and elasticity are essential to understanding any adhesive system. In this study of an adhesion surface in the tree frog, Litoria caerulea White...

...Tamatha R. Barbeau; Harvey B. Lillywhite SUMMARY Body wiping behavior, integumentary secretions and rates of evaporative water loss (EWL) were examined in six species of Florida tree frogs (Anura:Hylidae). Additionally, morphology of the integument and dermal glands were compared among...

...Makoto Takada; Miyoko Kasai SUMMARY The short-term effect of prolactin on the skin of the adult tree frog Hyla arborea japonica was investigated using current-fluctuation analysis. Basolateral application of ovine prolactin (10 μg ml -1 ) (1) increased the amiloride-blockable short-circuit current...

...MICHAEL G. McCAY SUMMARY Gliding has evolved independently in two families of tree frog. Tree frogs glide to descend rapidly to mating sites over temporary pools on the forest floor or to escape predators. The physical mechanisms used by frogs to glide and maneuver were investigated using...

...Richard L. Marsh ABSTRACT The sound-producing muscles of frogs and toads are interesting because they have been selected to produce high-power outputs at high frequencies. The two North American species of gray tree frog, Hyla chrysoscelis and Hyla versicolor , are a diploid–tetraploid species pair...

... of North American gray tree frog, Hyla chrysoscelis and Hyla versicolor . These trunk muscles contract cyclically, powering high-intensity sound production in anuran amphibians. The external oblique muscles in H. chrysoscelis have an in vivo operating frequency of 40–55 Hz at 20–25 °C, whereas in H...

...S. A. Dunlop; S. R. Moore; L. D. Beazley ABSTRACT Patterns of vascularisation were examined in whole-mounted retinae from tadpole stages to adulthood in the tree frog Litoria moorei using perfusion with Indian ink. Changing cell densities in the underlying ganglion cell layer were studied...
