Behavioral responses of laboratory-reared and wild-caught Polypedates maculatus (Anura: Rhacophoridae) tadpoles to dietary cues from the carnivorous tadpoles of Hoplobatrachus tigerinus (Anura: Dicroglossidae)

Phyllomedusa: Journal of Herpetology, 2023
The behavioral responses of laboratory-reared and wild-caught tadpoles of Polypedates maculatus to predatory tadpoles of Hoplobatrachus tigerinus were studied in the laboratory.

Locomotion and survival of two sympatric larval anurans, Bufo gargarizans (Anura: Bufonidae) and Rana zhenhaiensis (Anura: Ranidae), after partial tail loss

Zoologia (Curitiba), 2014
Tadpoles of two sympatric anurans, Bufo gargarizans Cantor, 1842 and Rana zhenhaiensis Ye, Fei & Matsui, 1995, were used as model organisms to examine the effects of different levels of tail loss on swimming performance and survival.

Tadpoles and gauge symmetries

Journal of High Energy Physics, 2023
Abstract The tadpole conjecture proposes that complex structure moduli stabilisation by fluxes that have low tadpole charge can be realised only at special points in moduli space, leading generically to (large) gauge symmetries. Here we provide an exhaustive survey of the gauge symmetries arising in F-theory flux compactifications ...

Sensory basis of food detection in tadpoles of Polypedates maculatus (Anura: Rhacophoridae): an experimental approach

Phyllomedusa: Journal of Herpetology, 2022
The mechanism of food detection in tadpoles of Polypedates maculatus was experimentally tested. We used a rectangular glass test tank with stimulus zones in opposite ends to provide visual and/or chemical food.

Comparative vulnerability of Indosylvirana temporalis and Clinotarsus curtipes (Anura: Ranidae) tadpoles to water scorpions: importance of refugia and swimming speed in predator avoidance

Phyllomedusa: Journal of Herpetology, 2021
The comparative vulnerability of two co-existing tadpole species (Indosylvirana temporalis and Clinotarsus curtipes) to their common predator, water scorpions (Laccotrephes sp.; Hemiptera: Nepidae), and the importance of refugia in predator avoidance ...

Strigea robusta causes polydactyly and severe forms of Rostand’s anomaly P in water frogs

Parasites & Vectors, 2020
Background Cases of polydactyly in natural populations of amphibians have attracted great interest from biologists. At the end of the 1940s, the French biologist Jean Rostand discovered a polymorphic syndrome in some water frog (Anura: Pelophylax ...

Survey of mercury in boreal chorus frog (Pseudacris maculata) and wood frog (Rana sylvatica) tadpoles from wetland ponds in the Prairie Pothole Region of Canada

FACETS, 2017
Tadpoles are important prey items for many aquatic organisms and often represent the largest vertebrate biomass in many fishless wetland ecosystems. Neurotoxic mercury (Hg) can, at elevated levels, decrease growth, lower survival, and cause developmental

Anomalies & Tadpoles

, 2000
We show that massless RR tadpoles in vacuum configurations with open and unoriented strings are always related to anomalies. RR tadpoles arising from sectors of the internal SCFT with non-vanishing Witten index are in one-to-one correspondence with conventional irreducible anomalies.

Anuran tadpoles inhabiting a fluoride-rich stream: diets and morphological indicators

Heliyon, 2019
We in situ assessed the influence of natural fluoride concentrations in lotic freshwater ecosystems on diet and morphology of Boana cordobae tadpoles. Two streams were sampled in Argentina: Los Vallecitos stream (LF-LV) and Los Cerros Negros stream (HF ...

Effects of light and group size on the activity of wood frog tadpoles (Rana sylvatica) and their response to a shadow stimulus

Acta Herpetologica, 2009
Tadpoles are known to behaviorally respond to cues from aquatic predators. However, there are several additional factors that might affect tadpole behavior.
