Population genetics of wood frogs (Lithobates sylvaticus) in a forested ridge-top wetland ecosystem
<p>An important aspect of conservation biology is understanding how land-use changes impact biodiversity. Ridge-top wetlands are unique habitat for pond-breeding amphibians and the Daniel Boone National Forest (DBNF) contains natural forested ridge-top wetlands in close proximity to constructed …

Assessing the Impacts of Agricultural Land Use on Wood Frog (Lithobates sylvaticus) Presence and Health in Central Saskatchewan
… amphibians in this region is the wood frog (Lithobates sylvaticus), a wide-ranging species that occupies a variety of ecosystems, from forests to prairies to tundra. This makes it an ideal model species to compare results in ecological and toxicological studies. Given anecdotal reports of …

The role of embryonic risk cues on the life history, morphology and behaviour of the wood frog Lithobates sylvaticus
… can produce disturbance cues. Using wood frog (Lithobates sylvaticus) embryos, I explored the existence of embryonic disturbance cues and their effects on hatching time, morphology, post-embryonic behaviour and growth during the larval stage, as well as the effect of embryonic alarm cues. …

Body Size And Habitat Shading Influence The Consumptive And Non-Consumptive Effects Of Wood Frog (lithobates Sylvaticus) Tadpoles On Aquatic Invertebrate Communities
… study were to quantify omnivory among wood frog (Lithobates sylvaticus) tadpoles, determine their consumptive and non-consumptive effects on invertebrate communities, and investigate whether such effects are mediated by habitat shading and tadpole body size. Lithobates sylvaticus tadpoles and egg …

Amphibians in a changing world: assessing the effects of warming and drying on amphibian larvae and the relationships between larval survival, body size, and time to metamorphosis
… of two amphibian species, wood frogs (<em>Lithobates sylvaticus</em>) and spring peepers (<em>Pseudacris crucifer</em>), to simulated warming and drying in experimental ponds. Over 13 weeks, we manipulated temperature and water levels in ponds to produce 4 treatments: control, drying, …

Physical and Biological Drivers of Wetlandscape Biogeochemistry
… amphibian in Delmarva wetlands are wood frog (Lithobates sylvaticus) tadpoles. I found that wood frog tadpole aggregations elevated nutrient recycling, microbial metabolism, and carbon cycling in Delmarva wetlands. These results provide evidence for the functional and biogeochemical role of …

Interactions between Eastern Newts and Wood Frogs in an anthropogenically altered wetland system in eastern Kentucky
… with short larval periods (e.g., Wood Frogs [<em>Lithobates sylvaticus<em>] and Marbled Salamanders [<em>Ambystoma opacum<em>]). Over the last 25 years, hundreds of wetlands have been constructed within the ridge-top ecosystem as permanent water sources for wildlife (i.e., game species). …

Amphibian Community Composition And Disease Susceptibility In Ridge-Top Wetlands Of The Daniel Boone National Forest
… to historic species, such as wood frogs (Lithobates sylvaticus) and marbled salamanders (Ambystoma opacum); these were game wetlands with shallower littoral zones and more complex basin vegetation that mimicked natural wetland characteristics. However, because none of the constructed …

Amphibian and plant communities of natural and constructed upland-embedded wetlands in the Daniel Boone National Forest
… wetlands were associated with wood frogs (Lithobates sylvaticus) and marbled salamanders (Ambystoma opacum) and constructed wetlands were associated with green frogs (L. clamitans), eastern newts (Notophthalmus viridescens), and spotted/Jefferson salamanders (A. maculatum, A. …
