“…cicada exhibits two larval oral configurations that develop following two different trajectories. A configuration with a ventral gap was previously described [65], and in half of our samples we observe comparable transient morphologies (e.g., Fig 10B); thus in these embryos we interpret an ontogenetic trajectory similar to that of the Ph . henselii group.…”

The study of early development in Neotropical Leiuperinae frogs (Anura, Leptodactylidae) has been addressed by several works in recent times. However, a comparative developmental approach under a phylogenetic context was not available. Herein we analyzed the morphological and ontogenetic diversity of embryos belonging to 22 species of the three largest genera in Leiuperinae. We find that in most cases, variations fit with the phylogeny at the inter- and intrageneric levels. Embryo kyphosis and whitish color are synapomorphies for the clade grouping Physalaemus and Engystomops . The presence of a third lower tooth row on the oral disc is plesiomorphic for Leiuperinae, only changing in derived clades. The configurations and developmental trajectories of the lower lip are exceptionally diverse. The developmental sequences optimized on the phylogenetic tree recover an early differentiated first lower tooth row a synapomorphy of Pseudopaludicola and Physalaemus , and an early differentiated second row as synapomorphy of Pleurodema . On the other hand, few features are highly conserved in the subfamily, such as the adhesive glands universally present in a type-C configuration. Our results also suggest that the morphology and ontogeny of embryos is in some cases associated to the environment where they develop. A large body size, poorly developed transient respiratory structures, large yolk provision and delayed development of the digestive tract occur convergently in embryos inhabiting cold, oxygenated environments. Embryos that develop in warmer water bodies in xeric environments show more complex and persistent transient respiratory structures and an early onset of hind limbs development. Our survey highlights that morphology and early development of anurans can be a valuable source of information for phylogenetic studies, and provide fundamental bases to explore and discuss how evolutionary changes can be shaped by environmental conditions.

“…The lower lip may have a mental gap and/or ventrolateral gaps, or the papillary may be continuous. Tadpoles of P. aguirrei, P. albifrons, P. centralis, P. cicada, P. cuvieri, P. henselii, and P. marmoratus have gaps in the lower lip (Pimenta & Cruz, 2004;Oliveira et al, 2010;Rossa-Feres & Jim, 1993;Vieira & Arzabe, 2008;Heyer, 1990;Kolenc et al, 2006;Nomura et al, 2003).…”

“…These larvae are typical pond-living tadpoles that are assumed to occur in the bottom of these lentic water bodies (Rossa-Feres et al, 2004;Vera Candioti, 2007) and are very similar to one another regarding to their external morphology (Vieira & Arzabe, 2008).…”

There are 45 species currently described for the genus Physalaemus that are allocated into seven morphological groupsand 29 of them have their tadpoles described, of which 12 have information on their internal oral anatomy. In order to helpresolving taxonomic and systematic problems, tadpoles from this genus had their external and internal oral morphologiesstudied, described and compared. During this study, it was noticed that different terms are sometimes used to refer to thesame character and a standardized nomenclature is suggested. This study is divided into two parts. First, we describe theoral cavity anatomy of the tadpoles of Physalaemus aguirrei, P. atlanticus, P. camacan, P. cicada, P. gracilis, P. irroratus,P. maximus, P. rupestris, P. signifer and P. soaresi. Second, we present a comparison among tadpoles of these ten speciesplus the tadpoles of P. albifrons, P. angrensis, P. centralis, P. crombiei, P. cuvieri, P. henselii, P. jordanensis, P. marmora-tus, P. moreirae and P. spiniger. This study adds information on tadpoles of the genus Physalaemus that corroborates someof the species groups proposed for adult specimens, but also shows that although they have a typical pond-living externalmorphology, being very similar to one another, the oral disc and the internal oral morphologies present many features with interspecific variation that may be used to identify the specimens.

“…Environmental shifts potentially affect species, especially in life cycle stages most susceptible to ambient changing conditions. In this sense, the use of larval characters is very common among herpetologists -both for the diagnosis of species and for determination of intra-and intergeneric systematic relationships (Carneiro et al, 2004;Nascimento and Skuk, 2006;Casal and Juncá, 2008;Vieira and Arzabe, 2008).…”

Longevity and survival curves of Rhinella icterica (Anura, Bufonidae) under laboratory conditions

2014

Life tables and survival curves of tadpoles from Rhinella icterica species were studied in the laboratory, under abiotic conditions controlled by a purification filter, a timer and a chiller. The survival curve for larval stage confirms a great mortality trend in the initial stages, which decreases when reaching the mature morphological condition (r = -0.94). Stages 37, 38, 39, 40 and 41 showed gradual values for their age structures, while stages 42, 43 and 44 presented high variations. Based on the results under laboratory conditions, it can be concluded that the maturity of R. icterica tadpoles development between 37 and 44 stages has a negative correlation and their predicted life expectancy is a logarithmic growth curve (y=-761.96Ln(x)+5298.5).Keywords: tadpole, life table, reproduction. Longevidade e curva de sobrevivência de Rhinella icterica(Anura, Bufonidae) em condições de laboratório ResumoTabelas de vida e curvas de sobrevivência em estágios larvais de girinos da espécie Rhinella icterica foram estudadas em laboratório, sob condições abióticas controladas com uso de filtro de depuração, timer e chiller. A curva de sobrevivência por estágio larval confirma a tendência de maior mortalidade para os estágios iniciais e menor mortalidade para o avanço da condição morfológica madura (r = -0,94). Os estágios 37, 38, 39, 40 e 41 apresentaram valores gradativos para sua estrutura etária, enquanto nos estágios 42, 43 e 44 ocorreram variações acentuadas. Com base nos resultados obtidos, nas condições de laboratório, pode-se concluir que a maturidade de desenvolvimento de girinos de R. icterica entre os estágios 37 e 44, apresenta correlação negativa e a predição de esperança de vida a uma curva logarítmica de crescimento (y=-761,96Ln(x)+5298,5).Palavras-chave: girino, tabela de vida, reprodução.
