Predation and competition can induce important density- and trait-mediated effects on species, with implications for community stability. However, interactions of these factors with parasitism remain understudied. Here we investigate interactions among competition, predation and parasitism by crossing tadpole density (Bufo americanus), presence of a caged predator (Notophthalmus viridescens), a...

The development of a wireless undulatory tadpole robot using ionic polymer–metal composite (IPMC) actuators is presented. In order to improve the thrust of the tadpole robot, a biomimetic undulatory motion of the fin tail is implemented. The overall size of the underwater microrobot prototype, shaped as a tadpole, is 96 mm in length, 24 mm in width, and 25 mm in thickness. It has one polymer fi...

Rabbits were immunized with frog or tadpole haemoglobin purified either by chromatography or by polyacrylamide gel electrophoresis. The obtained rabbit antisera were shown to be specific for frog or tadpole haemolysates by double diffusion, immunoprecipitation and immunonuorescence. Indirect immunofluorescent staining of peripheral blood smears of Rana catesbeiana tadpoles at the metamorphic cl...

In this brief report we show that tadpole diagrams due to KK modes of the graviton and radion do not contribute to the vectorial isospin breaking ρ parameter. Our result is fairly general and it holds both for ADD and RS type scenarios. It shows that the difference between the results of different publications on this subject is not due to some of them not having considered tadpole diagrams in ...

A bstract We examine the mechanism of moduli stabilization by fluxes in limit a large number moduli. conjecture that one cannot stabilize all complex-structure F-theory at generic point space (away from singularities) satisfy bound imposed tadpole cancellation condition. More precisely, while goes like 1 / 4 moduli, we amount charge induced stabilizing grows faster than this, and is therefore l...

Erythroid ferritin was isolated from tadpole red blood cells, an unusually abundant source, with an iron content of 12%. The apoprotein was characterized by sedimentation equilibrium studies, sodium dodecyl sulfate gel electrophoresis, and by determination of amino acid composition. Tadpole red cell apoferritin has a molecular weight of 478,000, a subunit size of 19,600, and an amino acid compo...

There have been contradictory reports of the relative proportion of mercury from coal-fired power plants that deposits locally. Our objective was to determine any local effect of coal-fired power plants on total mercury concentrations in wetland sediment and tadpole samples. Four power plants and 45 wetlands were selected for study. Total mercury concentrations were determined in 75 sediment sa...
