Power output of sound-producing muscles in the tree frogs Hyla versicolor and Hyla chrysoscelis.
Sound-producing muscles provide the opportunity of studying the limits of power production at high contractile frequencies. We used the work loop technique to determine the power available from the external oblique muscles in two related species of North American gray tree frog, Hyla chrysoscelis and Hyla versicolor. These trunk muscles contract cyclically, powering high-intensity sound product...
متن کاملA Morphometric Comparison of Gray Treefrogs, Hyla chrysoscelis and H. versicolor, from Ohio
Thirteen morphometric characters were compared between two cryptic species of gray treefrogs from Ohio. Discriminant function analysis using snout-vent length, shank length, and thigh length correctly classified 76.7% of diploid Hyla chrysoscelis and tetraploid//. versicolor. Ohio diploids are more similar in size to those in Texas than to those of Michigan and Wisconsin or southeastern states....
متن کاملGeographic variation in energy storage and physiological responses to freezing in the gray treefrogs Hyla versicolor and H. chrysoscelis.
The physiological responses supporting freeze tolerance in anurans are well known, but the evolution of this trait remains little studied. This is the first common-garden study of geographic variation in cryoprotective responses to freezing and the degree of freeze tolerance. We studied the gray treefrogs (Hyla versicolor and H. chrysoscelis) from sympatric sites in Minnesota, Indiana and Misso...
متن کاملFrequency channel-dependent selectivity for temporal call characteristics in gray treefrogs, Hyla versicolor.
Sensory receptors transmit information on multiple stimulus dimensions. Much remains to be understood about how the processing of different signal characteristics is partitioned and integrated in different areas of the nervous system. Amphibian hearing involves two morphologically distinct inner-ear organs that process different components of the frequency spectrum. Many anuran signals contain ...
متن کاملAdvertisement call of Hyla jimi and Hyla elianeae (Anura, Hylidae) in the Botucatu region, São Paulo, Brazil.
In this work we present a description of the advertisement call of H. jimi, the locality type, and of H. elianeae, until now unknown in the literature. Field activities were carried out from August 1997 through June 1999; recordings were made in two open-area environments in the Botucatu region, São Paulo State. Vocalizations of 100 individuals (49 H. jimi and 51 H. elianeae) were recorded; nin...
