Signals from predators, injured conspecifics, and pesticide modify the swimming behavior of the gregarious tadpole Rhinella dorbignyi (anura: bufonidae)
(National Research Council Canada-NRC Research Press, 2021-08)
Tadpoles detect chemical signals released from predators and conspecifics,aswellasthosepresentintheenvironment, and adjust their behavioral responses. This study evaluated the swimming activity of Dorbigny’s Toad(Rhinella ...
Tadpoles of Three Species of the Rhinella granulosa Group with a Reinterpretation of Larval Characters
(Sociedade Brasileira de Herpetologia, 2020-03)
The Rhinella granulosa group currently comprises 14 species of Neotropical toadswhose monophyly is strongly supported by several synapomorphies, including adistinctive set of larval characters. Recently, the identity of ...
Use of Lithobates catesbeianus tadpoles in a multiple biomarker approach for the assessment of water quality of the Reconquista River (Argentina)
(Springer, 2013-10)
The water quality of the Reconquista River (Argentina) water was monitored between 2009 and 2010 by means of a multiparametric approach. This periurban river is affected by agricultural, urban, and industrial discharges. ...
Comparative toxicity of two different dimethoate formulations in the common toad (Rhinella arenarum) tadpoles
(Springer, 2019-12)
Dimethoate (D) are among the most commonly used organophosphates insecticides in the world. To evaluate the toxicity of two D formulations were selected as test organisms tadpoles of Rhinella arenarum. This toad species ...
Chondrocranium and visceral skeleton of Atelopus tricolor and Atelophryniscus chrysophorus tadpoles (Anura, Bufonidae)Condocraneos y esqueletos hiobranquiales de Atelopus tricolor and Atelophryniscus chrysophorus (Anura; Bufonidae) larvales
(Brill Academic Publishers, 2001-03)
Atelopus tricolor and Atelophryniscus chrysophorus have gastromyzophorous tadpoles. Aside from specific differences, the larval chondrocrania and visceral skeletons show several shared character states, including an almost ...
Effects of agricultural pond eutrophication on survival and health status of Scinax nasicus tadpoles
(Academic Press Inc Elsevier Science, 2008-12)
To test the hypothesis that eutrophication ponds modulate some aspects of the health responses and survival of anuran tadpoles, we conducted field experiments using Scinax nasicus as sentinel organism to evaluate the quality ...
Anatomy of anuran tadpoles from lentic water bodies: systematic relevance and correlation with feeding habits
(MAGNOLIA PRESS, 2007-09)
I studied anatomy, gut content, and the relationship among these traits in a set of anuran tadpoles. Larval stages (mainly Gosner stages 31–36) of nineteen species from various lentic environments were selected. Morphological ...
Effect of diet on carboxylesterase activity of tadpoles (Rhinella arenarum) exposed to chlorpyrifos
(Academic Press Inc Elsevier Science, 2017-01)
An outdoor microcosm was performed with tadpoles (Rhinella arenarum) exposed to 125 μg L−1 chlorpyrifos and fed two types of food, i.e., lettuce (Lactuca sativa) and a formulated commercial pellet. Acetylcholinesterase ...
Health status of tadpoles and metamorphs of Rhinella arenarum (Anura, Bufonidae) that inhabit agroecosystems and its implications for land use
(Academic Press Inc Elsevier Science, 2015-04)
Perturbations of water bodies near agricultural and livestock systems can affect embryonic and larval stages of anurans and negatively impact adult populations and structure of amphibian communities. This study is focused ...
