Amphibian predator-insect prey relationships are common in terrestrial habitats, but amphibian larvae are preyed upon by a variety of aquatic hemipterans in aquatic habitats. This paper suggests that the survival of the nymphs of the endangered aquatic hemipteran Kirkaldyia (=Lethocerus) deyrolli (Belostomatidae: Heteroptera) is directly and indirectly affected by the abundance of their amphibi...

I experimentally investigated the habitat use preferences of bullfrog (Rana catesbeiana) tadpoles of different ages (early, first-year vs. late, second-year, premetamorphic) in the laboratory. Early tadpoles showed a preference for non-vegetated areas, whereas late tadpoles showed no preference. Early tadpoles were seen more often over small, gravel substrate as opposed to large rocks, whereas ...

The use of frogs and tadpoles for disease vector control is still largely unexplored. Frogs are an important part of the ecosystem with a role for insect and pest control including mosquitoes. Available information suggests the existence of many direct and indirect factors affecting the growth and survival of both prey and predators. Other controphic species that have influence on this relation...

Little is known about the life history, ecology, and distribution of genus Allopaa (Dicroglossidae) far less recent data are available larvae this taxon. Here, we provide on larval stage hazarensis (Dubois & Khan, 1979) from northern Pakistan based examination three tadpoles. Specimens were obtained two sites in Buner, Khyber Pakhtunkhwa province, Pakistan. Morphological genetic analysi...

We measure the spatiotemporal field of ultrashort pulses with complex spatiotemporal profiles using the linear-optical, interferometric pulse-measurement technique SEA TADPOLE. Accelerating and decelerating ultrashort, localized, nonspreading Bessel-X wavepackets were generated from a approximately 27 fs duration Ti:Sapphire oscillator pulse using a combination of an axicon and a convex or conc...

Predator-induced phenotypic plasticity has been widely documented in response to native predators, but studies examining the extent to which prey can respond to exotic invasive predators are scarce. As native prey often do not share a long evolutionary history with invasive predators, they may lack defenses against them. This can lead to population declines and even extinctions, making exotic p...
