The ontogeny of this species was divided into three phases: Help Center Find new too papers in: The reproductive cycles of males and females, the existence of sexual dimorphism and the male’s vocalization period were analyzed.

Reproductive aspects of Dendropsophus sanborni Anura, Hylidae in northeastern Argentina. In stage I the oogonia d are grouped surrounded by a layer of pre follicular cells. Stage II is characterized by the initiation and meiotic arrest of prophase and primary oocytes.

The histological analysis showed that from E. Bidart Campos, German J.

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.

And neonatos of 4, 13 and 25 days post-hatching cpnstitucion. The species showed sexual dimorphism in body mass, with females larger than males.

During ovarian ontogeny of birds can recognize five key events: Therefore we propose some hypotheses about possible heterochronic events related bidaft altricial-precocial developmental models. Enter the email address you signed up with and we’ll email you a reset link. Los argumentos intuitivos e informales conservan una claridad apropiada. 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.

From stage III starts follicular cells surrounding each oocyte culminating in the organization of primordial follicles stage IV. Dendropsophus sanborni showed a prolonged reproductive pattern because reproductive activity was observed during most part of the year. Columbiformes from an altricial-precocial perspective. La ontogenia de dicha especie fue dividida en tres etapas: 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.

Th is paper describes the changes and cellular events involved in manuap formation of the follicles of Columba livia. In males, snout-vent length was significantly correlated with mean testicular volume. To do this, we examined the histology ovarian from stage embryos E42 and neonates, 2, 5, 7, 10 and 14 constituvion post hatch. All Departments 28 Documents Researchers. 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.

Calling males were recorded all months except in July. Acd acordada de tasas. 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.

Future studies will focus on the analysis of diff erentiation processes of follicular cells and endocrine control in the process.

The spermatogenic cycle can be characterized as potentially continuous. Las demostraciones y los desarrollos, son descritos de manera suficiente, pero sin cansar demasiado al estudiante. 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.
