Early development of the glass frogs Hyalinobatrachium fleischmanni and Espadarana callistomma (Anura: Centrolenidae) from cleavage to tadpole hatching

  title={Early development of the glass frogs Hyalinobatrachium fleischmanni and Espadarana callistomma (Anura: Centrolenidae) from cleavage to tadpole hatching},
  author={Mar{\'i}a Jos{\'e} Salazar-Nicholls and Eugenia M. del Pino},
—We report the characteristics of embryonic development from cleavage to tadpole hatching in two species of glass frogs, Hyalinobatrachium fleischmanni and Espadarana callistomma (Anura: Centrolenidae. [] Key Method These frogs reproduced in captivity and their embryos were fixed for developmental analysis. The morphology of embryos was evaluated in whole mounts, bisections, thick sections, and fluorescent staining of cell nuclei. Egg clutches contained an average of 23 and 35 eggs for H. fleischmanni and E…

Embryogenesis of Marsupial Frogs (Hemiphractidae), and the Changes that Accompany Terrestrial Development in Frogs.

The comparison of early development reveals that gene expression is highly conserved among frog species, and indicates that a major event in the evolution of frog terrestrial development is the separation of convergent extension from gastrulation.

Structural and Heterochronic Variations During the Early Ontogeny in Toads (Anura: Bufonidae)

This work analyzes the development of transient embryonic and larval structures in 21 species in five genera of Bufonidae, finding that primary morphological variations occur in the morphology at the tail-bud stage, the arrangement and development of the external gills, adhesive gland type and division timing, and presence of the abdominal sucker.

Phyllomedusa 19-2 INGLÊS.indd

The results provide baseline data for the monitoring of anuran population dynamics in the Andean region using the glass frog N. grandisonae as a model system and find that the reproductive activity of N.grandisonae was seasonal and occurred in months with highest precipitation.

A polymorphism in oocyte pigmentation in natural populations of the glass frog Espadarana prosoblepon (Centrolenidae).

Evidence is presented of a polymorphism in egg pigmentation in the emerald glass frog Espadarana prosoblepon that is exclusive of oocyte cortical melanic pigmentation, which is reduced in comparison to wild type (wt) dark pigmented oocytes.

The poverty of adult morphology: Bioacoustics, genetics, and internal tadpole morphology reveal a new species of glassfrog (Anura: Centrolenidae: Ikakogi) from the Sierra Nevada de Santa Marta, Colombia

Using tadpole morphology, vocalizations, and DNA, a new species is described from the Sierra Nevada de Santa Marta, an isolated mountain range in northern Colombia, which offers insights about the ancestral character-states of adults, egg clutches, and larval features in this lineage of frogs.

The Advertisement Call and Notes on the Reproductive Ecology of the Glassfrog “Centrolene” quindianum (Anura: Centrolenidae)

The advertisement call and aspects of the breeding biology of “Centrolene” quindianum, a threatened species endemic to the Andes of Colombia whose taxonomic status and phylogenetic relationships require clarification are described.

Experiences with the marsupial frogs: Reminiscences of a developmental biologist.

  • 2020
Eugenia M. del Pino analyzed the biology and development of the marsupial frog Gastrotheca riobambae in comparison with Xenopus laevis and tropical frogs and described two modes of gastrulation in frogs according to the timing of notochord elongation.

Phylogeny-based species delimitation and integrative taxonomic revision of the Hyalinobatrachium fleischmanni species complex, with resurrection of H. viridissimum (Taylor, 1942)

This work tests the hypothesis of cryptic species within H. fleischmanni by means of morphology, morphometrics, bioacoustics, and molecular analysis, and supports the recognition of at least three different species within the name H. Fleisch manni.



Notes on husbandry, reproduction and development in the Pacific horned frog Ceratophrys stolzmanni (Anura: Ceratophryidae), with comments on its amplexus

Techniques for husbandry and reproduction, as well as reproductive and developmental features, are reported, pivotal for captive-management programmes related to conservation, education and hobbyist activities.

Development of the dendrobatid frog Colostethus machalilla.

Although C. machalilla does not form an embryonic disk, its thick blastopore lips resemble the embryonic disk of the marsupial frog Gastrotheca riobambae and represent an interesting deviation from the gastrulation pattern observed in X. laevis.

Observations on the Reproductive Behavior of a Neotropical Glassfrog, Hyalinobatrachium fleischmanni (Anura: Centrolenidae)

In regions where H. fleischmanni and T. cirrhosus co-occur, both calling males and egg masses were more frequently found on ‘less exposed’ lower surfaces of leaves, where risk of attack from aerial predators may be reduced.

Embryogenesis and laboratory maintenance of the foam‐nesting túngara frogs, genus Engystomops (= Physalaemus)

This work reports on the early development, rearing, and embryological analysis of túngara frogs (genus Engystomops), also called Physalaemus, which are attractive for comparative and genetic studies of development.

Gastrulation of Gastrotheca riobambae in comparison with other frogs.

A comparative analysis of frog early development

The expression of Lim1 in the dorsal lip of the blastopore and notochord differed among the studied frogs, indicating variation in the timing of developmental events, and gives evidence of the modular character of frog gastrulation.

Oviposition, Site Preference, and Evaluation of Male Clutch Attendance in Espadarana andina (Anura: Centrolenidae)

There was no difference in site selection for calling, mating, and oviposition between dry and rainy seasons and among months.

The expression of Brachyury (T) during gastrulation in the marsupial frog Gastrotheca riobambae.

The separation of gastrulation events in embryos that have not been experimentally manipulated, such as those of Gastrotheca, helps in understanding the distinct nature of gastRulation processes.

Developmental diversity of amphibians

The wealth of developmental diversity among amphibians coupled with the wealth of mechanistic information from X. laevis permit comparisons that provide deeper insights into developmental processes.
