Desarrollo neural, somitogénesis y morfología interna de los embriones de Hyloxalus vertebralis y Dendrobates auratus (Anura: Dendrobatidae)
Contenido principal del artículo
Resumen
Se analizaron y compararon las características de la neurulación, morfología interna de los embriones desde la néurula hasta la eclosión del renacuajo y el modo de miogénesis de dos especies de ranas de la familia Dendrobatidae (Hyloxalus vertebralis y Dendrobates auratus) con otras especies de la misma familia y Xenopus laevis. Se realizó este análisis debido a que los huevos de H. vertebralis y D. auratus tienen el tamaño más grande detectado hasta ahora en la familia Dendrobatidae (2.6 y 3.5 mm de diámetro, respectivamente). La morfología interna de los embriones y la neurulación de H. vertebralis y D. auratus fueron similares a lo observado en X. laevis y otros Dendrobatidae. Se observó retraso en la diferenciación del cerebro en estas especies en comparación con X. laevis. La miogénesis de H. vertebralis y D. auratus ocurre por interdigitación celular como en Bombina variegata (Bombinatoridae), cuatro especies adicionales de Dendrobatidae, dos especies de Leiuperidae y una especie de Hemiphractidae. El estudio comparativo permite documentar la diversidad de programas del desarrollo entre los anuros y contribuir al conocimiento de la fauna ecuatoriana.
