Los argumentos intuitivos e informales conservan una claridad apropiada. The histological analysis showed that from E. 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.

Dendropsophus sanborni showed a prolonged reproductive pattern because reproductive activity was observed during most part of the year.

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. Therefore we propose some hypotheses about possible heterochronic events related to altricial-precocial developmental models. The reproductive cycles of males and females, the existence of sexual dimorphism and the male’s vocalization period were analyzed.

Log In Sign Up. Acd acordada de tasas. Th is paper describes the changes and cellular events involved in the formation of the follicles of Columba livia. From stage III starts follicular cells surrounding each oocyte culminating in the organization of primordial follicles stage IV. To do this, we examined the histology ovarian from stage embryos E42 and neonates, 2, 5, 7, 10 and 14 days post hatch.

Th e knowledge of these events is crucial for the interpretation of the processes involved in the diff bidary of female gametes. Enter the email address you signed up with and we’ll email you a reset link.

Studies of the development gonadal in birds have been studied in species model as Gallus gallus domesticus. In males, snout-vent length was significantly correlated with mean testicular volume. Stage II is characterized by the initiation and meiotic arrest of prophase and primary oocytes.

Embryonic development of Columba livia Aves: 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 ontogeny of this species was divided into three phases: Reproductive aspects of Dendropsophus sanborni Anura, Hylidae in northeastern 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. In stage I the oogonia nests are grouped surrounded by a layer of pre follicular cells. The aim of this investigation was to characterize reproductive aspects of Dendropsophus sanborni Schmidt, Anura, Hylidae in the northwest Aspectos reproductivos de Dendropsophus sanborni Anura, Hylidae en el nordeste de la Argentina.

La ontogenia de dicha especie fue dividida en tres etapas: The species showed sexual dimorphism in body mass, with females larger than males. Remember me on this computer.

Columbiformes from an altricial-precocial perspective.

The aim of this investigation was to characterize reproductive aspects of Dendropsophus sanborni Schmidt, Anura, Hylidae in the northwest of Corrientes province, in northeastern Argentina. 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.

Las demostraciones y los desarrollos, reformdaa descritos de manera suficiente, pero sin cansar demasiado al estudiante.

Calling males were recorded all months except in July. Th e observations made it possible to identify amnual stages of folliculogenesis. We analyzed the histological constitution of testicles of embryos from the stage E. The spermatogenic cycle can be characterized as potentially continuous.

And neonatos of 4, 13 and 25 days post-hatching dpe. Samples were processed according to conventional techniques for paraffi n embedding and staining with hematoxylin and eosin. Samplings were made from September to August 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.
