1. The peculiar breeding biology of the Amazonian frog Allobates subfolionidificans (Aromobatidae)
ABSTRACT Allobates subfolionidificans is a vulnerable and endemic leaf-litter frog from the state of Acre, Brazilian Amazonia. We monitored a population of A. subfolionidificans through regular censuses and mark-recapture of 181 individuals during an entire breeding season to characterize its reproductive behavior. The space use of A. subfolionidificans indi

2. What the largest tadpole feeds on? A detailed analysis of the diet composition of Pseudis minuta tadpoles (Hylidae, Dendropsophini)
ABSTRACT We analyzed the diet of 25 individuals of Pseudis minuta tadpoles which consisted in debris with more than 30%, follow by diatoms, euglenids, green algae, and desmids. With regard to the feeding strategy, P. minuta tadpoles are generalist consumer. The negative correlation between the abundance of items in the digestive tract and the mouth width ind

3. Pressure tolerance of tadpole larvae of the Atlantic ascidian Polyandrocarpa zorritensis: potential for deep-sea invasion
Resumo Dentre as teorias mais aceitas de como surgiu a fauna de oceano profundo está a de que organismos de águas rasas migraram para águas mais profundas e lá especiaram até originarem as comunidades de mar profundo atuais. No entanto, muitos organismos são impedidos de fazer longas migrações verticais por conta do aumento da pressão hidrostática.

4. The tadpole of Proceratophrys izecksohni (Amphibia: Anura: Odontophrynidae)
We describe the external morphology of the tadpole of Proceratophrys izecksohni Dias, Amaro, Carvalho-e-Silva & Rodrigues, 2013, its internal oral features, and chondrocranial anatomy, based on specimens collected at the type locality. The tadpole has short and oval body, spiracle with inner wall fused to the body, and oral formula 2/3(1). The oral cavity of

5. A hipóxia é um estressor para girinos de rã-touro?
Avaliou-se o cortisol em girinos de rã-touro (Lithobates catesbeianus), no estágio de pró-metamorfose ao mecanismo estressor de hipóxia juntamente com captura (1º experimento) e adensamento (2º experimento). O experimento de captura foi composto pelos tratamentos: Captura individual com puçá, Captura em massa com puçá e Captura por escoamento, com

7. Efecto del tamaño del hábitat en la supervivencia, desarrollo y crecimiento en renacuajos de Engystomops pustulosus (Anura: Leiuperidae) y Rhinella humboldti (Anura: Bufonidae)
Tadpole survival is strongly influenced by environmental factors such as temperature, oxygen, food, larval density, water volume and pond drying. Tadpoles of Engystomops pustulosus and Rhinella humboldti develop in ephemeral habitats with strong differences in their size (space and water volume) around the city of Ibagué, Colombia, and at the campus of the

8. DISTRIBUIÇÃO ESPAÇO-TEMPORAL DE COMUNIDADES DE GIRINOS (AMPHIBIA: ANURA) NO CERRADO SUL-MATO-GROSSENSE / SPATIO-TEMPORAL DISTRIBUTION OF TADPOLE COMMUNITIES (AMPHIBIA: ANURA) IN THE CERRADO OF MATO GROSSO DO SUL
Estudamos a riqueza, a abundância e a distribuição espaço-temporal de comunidades de girinos em oito poças em uma área de cerrado no estado do Mato Grosso do Sul, Brasil. Nós realizamos o presente estudo durante uma estação chuvosa (outubro de 2009 a março de 2010). Assim, determinamos a amplitude de nicho espacial e temporal, através do Índice d

9. Quantitative study of Trichodina heterodentata (Ciliophora: Mobilia) infrapopulations infesting tadpoles of a Brazilian endemic toad Rhinella pombali (Anura: Bufonidae)
In this work we investigated the quantitative aspects of the relationship between Rhinella pombali (Baldissera, Caramaschi & Haddad, 2004) tadpoles and their trichodinid ectoparasites. Specimens were collected from a small stream located at an agricultural area between rainforest fragments in southeastern Brazil. A total of 80 tadpoles were investigated. Tri

10. First record of partial albinism and scoliosis in Odontophrynus occidentalis tadpoles (Anura: Cycloramphidae)
Albinism has been widely reported for diverse group of vertebrates. However, scoliosis is a rare abnormality. In this work, the first record of partial albinism and scoliosis case in tadpole of the frog Odontophrynus occidentalis is being presented. The individual was captured in Quebrada de las Flores, Sierra Pie de Palo, Caucete Department, San Juan Provin

11. A redescription of Anomaloglossus praderioi (La Marca, 1998) (Anura: Aromobatidae: Anomaloglossinae), with description of its tadpole and call
Anomaloglossus praderioi was originally described as Colostethus praderioi by E. La Marca in 1998 on the basis of two male specimens. The present paper provides a redescription of the species on the basis of new material from Maringma Tepui in Guyana and an additional specimen from Sierra de Lema in Venezuela. The redescription includes descriptions of the t

12. Ultradiluição homeopática de triiodotironina altera a apoptose celular da cauda de girinos de Rana catesbeiana: in vitro / Ultra high dilution of triiodothyronine modifies the cellular apoptosis of Rana catesbeiana tadpole tail: in vitro
Ultra High Dilution (UHD) is the effect of a solution, beyond the Avogadro limits, that in the dependence of the applied dinamization (dilution with succussion) elicits a suppressive or a stimulant effect on a living cell, with a consequent generation of an oscillatory dose-effect curve. The entire process of anuran amphibian metamorphosis is under thyroid h
