Columbiformes from feformada altricial-precocial perspective. The histological analysis showed that from E. Los muestreos se efectuaron desde Septiembre de hasta Agosto de The ontogeny of this species was divided dde three phases: Therefore we propose some hypotheses about possible heterochronic events related to altricial-precocial developmental models. Th e knowledge of these events is crucial for the interpretation of the processes involved in the diff erentiation of female gametes.

Th e observations made it possible to identify four stages of folliculogenesis. In the birds, the gonads are organized and differentiate to dividing a couple of genital combs, which are constituted by Cells Germinate Primordial CGPsof origin extra-gonadal. The spermatogenic cycle can be characterized as potentially continuous. All Departments 28 Documents Researchers. In stage I the oogonia nests are grouped surrounded reformqda a layer of pre follicular cells.


Los argumentos intuitivos e informales conservan una claridad apropiada.

Dendropsophus sanborni showed a prolonged reproductive pattern because reproductive activity was observed during most part of the year. Log In Sign Up. To do this, we examined the histology ovarian from stage embryos E42 and neonates, 2, 5, 7, 10 and 14 days post hatch.

Remember me on this computer. The aim of this investigation was to characterize reproductive aspects of Dendropsophus sanborni Schmidt, Anura, Hylidae in the northwest Acd acordada de tasas.

Stage II is characterized by the initiation and meiotic arrest of prophase and primary oocytes. From stage III starts follicular cells surrounding each oocyte culminating in the organization of primordial follicles stage IV. Th e results obtained show that in Columba livia, unlike the other species studied, folliculogenesis begins after hatching, and raising new questions about the mechanisms of control of folliculogenesis.

The late phase stages shows the overall embryo growth, the final organization of the pterilosis pattern and growth of feather germs, as well as final consumption of the yolk, and hatching. Aspectos reproductivos de Dendropsophus sanborni Anura, Hylidae en el nordeste de la Argentina.

The middle phase stages was characterized mainly by the growth of limbs and the organization of the autopodium, the formation and growth of the peak, and the development of integumentary annexes such as feather germs and leg scales.

We analyzed the histological constitution of testicles of embryos from the stage E.


Future studies will focus on the analysis of diff erentiation processes of follicular cells and endocrine control in the process. Universidad Nacional del Nordeste Corrientes, Argentina. Post-ovulatory females were found from March to June and most females had oocytes at different stages of maturity, with abundant post-vitellogenic oocytes from August to December.

From these two models, the study of the development gonadal in different species of birds will help to elucidate variations in the patterns of development gonadal in vertebrates. Las redormada y los desarrollos, son descritos de manera suficiente, pero sin cansar demasiado al estudiante. Samplings were made from September to August Reproductive aspects of Dendropsophus sanborni Anura, Hylidae in northeastern Argentina.

Th is paper describes the changes and cellular events involved in the formation of the follicles of Columba livia.
