Non-Native Leaf Litter Modifies Algal Resources with Effects on Tadpole Growth
… litter species in the presence and absence of tadpoles. Early in the experiment, Japanese honeysuckle and Chinese privet decreased periphyton N:P ratios and stimulated tadpole growth compared to native leaf litters. However, tadpole mortality in Japanese honeysuckle was high over winter …

The Effects Of Acidic Conditions And Tannins On The Survival, Development, And Behavior Of Cope’s Gray Treefrog (Hyla Chrysoscelis)
… with the pH and tannin conditions that maximize tadpole survival and performance in the laboratory, and b) investigate the impacts of mildly acidic conditions, with and without the added stress of tannins, on the survival, development, and anti-predator behavior of Hyla chrysoscelis tadpoles. I …

Short-distance matrix elements for D-meson mixing for 2+1 flavor lattice QCD
… Collaboration's gauge configurations with $a^2$ tadpole-improved staggered sea quarks and tadpole-improved L\""uscher-Weisz gluons. We use the $a^2$ tadpole-improved action for valence light quarks and the Sheikoleslami-Wohlert action with the Fermilab interpretation for the valence charm quark. …

Possible Effects Of Climate Change On Induced Defenses In Tadpoles
… components of temporary pond systems, and their tadpoles can exhibit a great amount of plasticity in morphology and life history traits due to environmental change. For example, tadpoles can alter their morphology in response to specific predators. These induced defenses have been found to …

A Comparison of the Pectoral Spines in Virginia Catfishes
… margined madtom (Noturus insignis), and tadpole madtom (Noturus gyrinus).Pectoral spines and girdles grow as catfish increase in size. In larger species spine length and weight increase nonlinearly with fish size, suggesting that maintaining spine dimensions becomes less important in …

Intersecting brane landscape
… all combinations of branes with negative tadpole contributions. This provides the necessary information to systematically and efficiently identify all models in this class with specific characteristics. In particular, all ways in which a desired group G can be realized by a system of …

Body Size And Habitat Shading Influence The Consumptive And Non-Consumptive Effects Of Wood Frog (lithobates Sylvaticus) Tadpoles On Aquatic Invertebrate Communities
… attention in some groups. As aquatic consumers, tadpoles have traditionally been considered strict herbivores, leaving their predatory impacts via consumptive and non-consumptive interactions on aquatic invertebrates largely unexplored. The objectives of this study were to quantify omnivory among …

Effects of Infection of the Protist Parasite, Dermomycoides sp., in Dusky Gopher Frog Tadpoles
… zoospores, host developmental stage, and tadpoles' ability to acquire resistance to <em>Dermomycoides </em>sp. on dusky gopher frog tadpoles. Tadpoles were exposed to zoospore densities of 0, 250, 500, and 750 zoospores/µL at Gosner stage 25, and we found no significant differences among …

The effects of the invasive exotic Chinese tallow tree (Triadica sebifera) on amphibians and aquatic invertebrates
… leaf litter on anuran larvae (i.e., frog tadpoles). This question is important to our understanding of how allochthonous inputs to aquatic habitats drive biodiversity in wetlands. It also addresses a timely conservation concern in southeastern Louisiana where invasion by Chinese tallow …

The environmental physiology of Bufo bufo L. and Bufo calamita Laur. tadpoles.
… and metamorphosis in B. bufo and B. calamita tadpoles were investigated, together with a limited study on the effects of L-thyroxine. The effects of density on growth, developteI1t and metamorphosis were examined. Physiological and behavioural effects of B. bufo tadpoles on B. calamita …

Examining the impacts of pesticide exposure on the survivorship and development of the Great Basin Spadefoot (Spea intermontana) and the Pacific Treefrog (Pseudacris regilla) in a laboratory environment
… impact amphibian embryo survivorship and tadpole development, three insecticides currently used in British Columbia were tested at their detected field concentrations in a laboratory environment. The commercial formulations of endosulfan, azinphos-methyl and diazinon were tested alone and …

Studies in Amphibian Limb Development and Regeneration
… data by eliminating developmentally abnormal tadpoles from experimental pools and ensuring that sample sizes were large for statistically assessing normal baseline regeneration performance. We demonstrated that the degree of regeneration capability of the tadpole hindlimb was highly correlated …

Ecology and distribution of the Florida bog frog and flatwoods salamander on Eglin Air Force Base
… voice recognition is possible. I exposed tadpoles of bog frogs, bronze frogs, and leopard frogs (R. sphenocephala) to chemical cues from 2 predators, the banded water snake (Colubridae: Nerodia fasciata) and the red fin pickerel (Esocidae: Esox americanus) to evaluate whether swimming …

Effects of Sublethal Copper Exposure on Escape Behavior and Growth of Rana pipiens Tadpoles
… to test how sublethal exposure to copper affects tadpole predator-escape behavior and how quickly tadpoles recover. After exposure, tadpoles were separated. Escape behavior was recorded for two-thirds of exposed tadpoles while one-third of the exposed population was measured weekly to determine …
