This book was released on 2011 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphibian populations worldwide are in decline due to anthropogenic drivers. However, little is known about how changes to the larval environment may affect survival and future recruitment of the species specifically in those environments whose energetics are subsidized by allochthonous input such as litterfall. Using a manipulative mesocosms experment I found that changes in litter type had dramatic and differential affects on all levels of the mesocosm ecosystem including water chemistry, primary producer biomass, and on larval wood frog Rana sylvatica fitness traits. Notably, we found that senescent green ash (a specied of tree declining and at great risk due to the emerald ash borer) produced metamorphs that were larger than all other litter species used and developed at a faster rate with higher survival. This study, indeed, illustrates how regional changes in forest community structure can affect the local dynamics and the physiology of individuals within the forest pond.

This book was released on 2021 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenically-induced salinization of freshwater systems due to the application of road de-icing salts and hydrocarbon mining has been identified as a significant environmental stressor for amphibians across the United States. While the effects of salinity during amphibian embryonic and larval stages are fairly well-understood, less is known on whether these effects can carry over to affect post-metamorphic traits. Moreover, it remains unclear if salinity-induced carry-over effects are adaptive or maladaptive for amphibian survival, or if salinity can interact with other environmental conditions, like temperature, to influence amphibian development. To fill in these gaps, we tested the hypothesis that if wood frogs that develop in saline ponds exhibit adaptive plasticity in their osmoregulatory abilities, then individuals raised in elevated salinity environments as larvae would feature greater tolerance to similarly saline post-metamorphic environments (i.e., the match hypothesis). In addition, we also hypothesized that exposure to elevated salinity and temperature during larval development would have measurable impacts on juvenile behaviors. Our results provided no evidence for the match hypothesis, as juveniles reared in high salinities did not survive or grow better in high-salinity soils compared with those in low-salinity soils. However, we do show that juveniles that experienced elevated salinity as larvae tended to increase weight (but not SVL) regardless of post-metamorphic environment, suggesting that there may be differences in food intake or osmoregulation in these animals. We also showed that the interaction between salinity and temperature experienced during the larval stage affects wood frog explorative capacity without necessarily impacting exploitative behavior, providing evidence for behavioral carry-over effects. Taken together, these findings contribute to a growing body of work to show that the larval environment can affect the expression of physiological and behavioral traits after metamorphosis, but how these traits relate to population recruitment still needs to be investigated. Findings from this study also suggests that salinization of both freshwater and woodland soils adjacent to roads has adverse effects on wood frogs in both the aquatic and terrestrial parts of their life cycle.

This book was released on 2008 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both concern over amphibian declines (Dunson et al., 1992; Blaustein, 1994) and the potential of amphibians as indicators (Phillips, 1990; Dunson et al., 1992; Boyer and Grue, 1995) of ecosystem health provided the impetus for this study. Utilizing amphibians as indicator species is comparable to the use of "canaries in a coal mine" when assessing the quality of an aquatic environment (Barinaga, 1990). Embryos, tadpoles, and adults are considered to be sensitive to environmental contaminants in part due to their unshelled eggs and permeable skins (Bridges et al., 2002; Blaustein et al., 2003; Kiesecker et al., 2004; Hogan et al., 2006). Amphibians offer a unique biphasic life cycle for studying water and land habitats as well as the interactions between the two environments. This study investigated the interaction between two human-mediated environmental changes on the development of a common North American anuran, (Rana sylvatica) the Wood Frog. Anthropogenic changes have increased copper and sunlight in many amphibian habitats. Human disturbance often leads to a decrease in canopy cover, which thereby reduces shade for developing embryos and tadpoles of certain anuran species within the aquatic environments below (Werner and Glennemeier, 1999; Skelly et al., 2002). Water runoff from impermeable surfaces and agricultural and residential properties transport toxins and excess nutrients into bodies of water, leading to algal blooms. In ponds, a common algaecide utilized to eliminate the ensuing blooms is copper sulfate. This work investigated the effects of copper sulfate and increased solar radiation on the developmental rate and survival of Wood Frog tadpoles in high pH ponds. pH levels in Northeastern Ohio ponds are higher (7.0-8.5; Matson et al., unpublished data, 2006) than in many other areas of Wood Frog study and research is lacking in non-lab environments at these pH levels. A field study used cattle tanks for testing the influence of increased light, increased copper, and for interactions between these environmental perturbations. Copper was a significant source of variation in measures of tadpole developmental rate and marginally significant in tadpole survival. Shade was not a significant source of variation in survival, but did significantly slow development. In addition, copper and shade interacted in their effect on developmental rate as measured by an increase in body mass in ambient copper treatments. These results are beneficial in understanding whether the use of copper sulfate is a contributor to amphibian decline.

This book was released on 2019 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of roads across the landscape can have far-reaching effects on wildlife populations. It is not just the presence of traffic that endangers the wildlife living near roads, but also the wide range of chemicals that seep away from these roads and out into nature. For animals like amphibians, creatures with extremely permeable skin, the presence of these chemicals can be particularly harsh, imposing strong population fitness consequences. Here, I investigated the effects of sodium chloride exposure – a common road deicer – on a local amphibian, the wood frog (Rana sylvatica). Specifically, I evaluated tadpole swim performance and tail anatomy, along with pilot study into juvenile skin microbiome diversity. I found that swimming endurance differed across the interaction of body size and salt exposure: tadpoles raised in salt had lower endurance as they achieved larger sizes. This pattern suggests an energy trade-off might mediate the relationship between body size and salt exposure. Additionally, tadpoles raised at higher salinities have smaller lateral band tail muscles than those raised at lower salinities. Microbiome results were largely inconclusive, but indicated that salt exposure may mediate microbiome diversity on amphibian skin, suggesting that this area of research would benefit from further study.
