Distinguishing the Treefrogs "Hyla versicolor" and "Hyla chrysoscelis" in Iowa, and Their Distributions
… and diploid species pair of treefrogs, "Hyla versicolor" and "Hyla chrysoscelis" have been mapped collectively in Iowa because no distinguishing macroscopic morphological characteristics useful in recognizing the two species had been found. The present study reports identification and …

Aquaglyceroporin Expression and Regulation in Erythrocytes From Freeze Tolerant Cope’s Gray Treefrog, <i>Hyla Chrysoscelis</i>
Cope’s gray treefrog, <i>H. chrysoscelis</i> is a freeze tolerant anuran that accumulates glycerol as a cryoprotectant during cold acclimation. Aquaporins, members of the major intrinsic protein (MIP) family of transmembrane water pores, may play an important role in the mechanism of freeze …

The influence of ploidy level on the hearing sensitivity of the sister species Hyla chrysoscelis and Hyla versicolor
… of hearing. The North American gray treefrogs, Hyla chrysoscelis and Hyla versicolor, are nearly identical with the exception that the latter is tetraploid. Morphology, hearing performance, and histology of the ears were assessed to identify differences in the tuning and sensitivity of hearing …

The Effects Of Acidic Conditions And Tannins On The Survival, Development, And Behavior Of Cope’s Gray Treefrog (Hyla Chrysoscelis)
… development, and anti-predator behavior of Hyla chrysoscelis tadpoles. I conducted a field oviposition study to determine adult female site choice, and reared tadpoles in acidic and tannic conditions to investigate survival and antipredator behaviors. I found that female oviposition site …

Comparative Toepad Morphology in Chorus Frogs (Genus Pseudacris): Arboreal, Terrestrial, and Ground Dwelling Species
Toepad morphology was examined in the arboreal Hyla chrysoscelis, semiarboreal Pseudacris crucifer, terrestrial P. triseriata, P. brachyphona, and P. brimleyi, semiaquatic Rana catesbiana, and fossorial Pseudacris streckeri and ornata, and Gastrophryne carolinensis, using scanning electron …

Risk, Reward, And The Role Of Habitat Selection On Community Dynamics In Temporary Ponds
… populations of aquatic beetles and treefrogs. Hyla chrysoscelis selected habitats in which they minimized the risk of both desiccation and predation. Aquatic beetles selected habitats with more available resources, and their habitat preferences partitioned species among habitats based on the …

Anura of Eastern South Dakota: Their Distribution and Characteristics of Their Wetland Habitats, 1997-1998
… counties, along with the eastern grey treefrog (Hyla versicolor) and Cope's grey treefrog (Hyla chrysoscelis) occurring locally in this same area. Although no significant relationships existed between anuran occurrence and water regimes, seasonal and semipermanent wetlands provided habitat for …

Possible Effects Of Climate Change On Induced Defenses In Tadpoles
… I used Cope's gray treefrog tadpoles, Hyla chrysoscelis, as prey in an experiment that crossed two hydroperiod length treatments (short, long) with four predator treatments (caged Anax dragonfly nymph presence/absence x caged Belostoma water bug presence/absence) to address two …
