Functional Equivalency of Created and Natural Wetlands in the Central Appalachians: Reproductive Success, Call Phenology, and Diet Composition of Amphibians
… the spring and summer of 2009 and 2010, and 165 green frog (Lithobates clamitans) larvae were raised during the spring of 2010 in laboratory aquaria containing water from created or natural wetlands. Abundance of spring peeper (Pseudacris crucifer ) metamorphs decreased significantly from 2009 to …

Non-Native Leaf Litter Modifies Algal Resources with Effects on Tadpole Growth
… leaf litter species on algal resources and green frog, <em>Lithobates clamitans</em>, development using a randomized complete block experiment that lasted 288 days. In experimental ponds, I added two non-native and two native leaf litter species in the presence and absence of tadpoles. Early …

Prevalence assessment of the amphibian chytrid fungus Batrachochytrium dendrobatidis across two habitat types in East Tennessee
… inform management decisions. Using American Bullfrogs (Lithobates catesbeianus) and Green Frogs (Lithobates clamitans) as study organisms, this research sought to investigate how prevalence of Bd varies between natural wetlands and urban retention ponds in East Tennessee while also examining …

Interrelationships of conspecific responses to call quality and body size of male Rana clamitans (Anura: Ranidae)
… is significant because Sachs (1964) found that green frog auditory perception of low-frequency sounds is inhibited if sufficient energy is also present in the middle-frequency range. Thus calls of small males having low EIR scores may be poorly perceived by conspecifics. Playback of a small male …

Isolation, Structures, Synthesis and Biological Activities of Non-Mammalian Vertebrate Endothelins
… mykiss and the steroidogenic effects of frog ETs in the perifused frog adrenal gland. Therefore, the present work contributed to the understanding of the molecular and functional evolution of the ET family. ET is generally secreted by a constitutive pathway so that steady-state …

Amphibian and plant communities of natural and constructed upland-embedded wetlands in the Daniel Boone National Forest
… co-occurring natural ephemeral wetlands. Wood frog and marbled salamander larvae are found almost exclusively in natural wetlands and green frog larvae and eastern newts are found in constructed wetlands. It is currently unknown whether plant communities at these constructed wetlands are …

Isolation and Characterization of Regulatory Peptides from Two Tetraploid Species, the Pallid Sturgeon, Scaphirhynchus albus, and the African Clawed Frog, Xenopus laevis
… extracts from the African clawed frog, Xenopus laevis. Peptides were purified by reversed-phase HPLC and characterized by electrospray ionization mass spectroscopy (ESI-MS) and automated Edman degradation.The single form of insulin isolated from the pallid sturgeon is identical to …
