Frogs are cold-blooded animals, and their physiology is affected by variations in temperature. advertisement‐call preferences in diploid‐tetraploid treefrogs (hyla chrysoscelis and hyla versicolor): implications for mate choice and the evolution of communication systems H. Carl Gerhardt Division of Biological Sciences, University of Missouri, Columbia, Missouri 65211 E‐mail: gerhadth@missouri.edu Call: Call is a musical trill. Hyla chrysoscelis. Field biologists wanted to know if the mating call of H. chrysoscelis is affected by the temperature of its natural habitat. Here's a potentially confusing call from Kendall County, Texas. Eggs, laid in packets attached to vegetation at water's surface, hatch in a few days and tadpoles transform in about two months.
However, it also has the ability to blend into its surroundings by changing colors from green, brown or white. Hyla chrysoscelis is a type of gray tree frog with a distinct mating call.
Reproductive character displacement re-sults in the accentuation of isolating mech-anisms in the area of sympatry (White, 1978). Description: The Gray Treefrog's back is usually two-toned gray with a broad patch of darker gray at the center.
Interesting Facts: Hyla chrysoscelis is morphologically indistinguishable from H. versicolor and two species are also sympatric throughout much of their ranges. Other resolutions: 320 × 180 pixels | 640 × 360 pixels | 1,077 × 606 pixels. This is Hyla chrysoscelis, but its pulse rate is around 36 pulses per second, giving it an almost Hyla versicolor sounding call.
