The histological analysis showed that from E. La ontogenia de dicha especie fue dividida en tres etapas: Samplings were made from September to August Reproductive aspects of Dendropsophus sanborni Anura, Hylidae in northeastern Argentina. From these two models, the study of the development gonadal in manul species of birds will help to elucidate variations in the patterns of development gonadal in vertebrates. The spermatogenic cycle can be characterized as potentially continuous.
We analyzed the histological constitution of testicles of embryos from the stage E. Remember me on this computer. In the birds, the gonads are organized and differentiate al dividing a couple of genital combs, which are constituted by Cells Germinate Primordial CGPsof origin extra-gonadal.

Th e knowledge of these events is crucial for the interpretation of the processes involved in the diff erentiation of female gametes. Click here to sign up. The ontogeny of this species was divided into three phases: Help Center Find new research papers in: Future studies will focus on the analysis of diff erentiation processes of follicular cells and endocrine control in the process. Aspectos reproductivos de Dendropsophus sanborni Anura, Hylidae en el fomo de la Argentina. Dendropsophus sanborni showed a prolonged reproductive pattern because reproductive activity was observed during most part of the year.
During ovarian ontogeny of birds can recognize five key events: In males, snout-vent length was significantly correlated with mean testicular volume.
Th e observations made it possible to identify four stages of folliculogenesis. Bidart Campos, German J. The aim of rreformada investigation was to characterize reproductive aspects of Dendropsophus sanborni Schmidt, Anura, Hylidae in the northwest The species showed sexual dimorphism in body mass, with females larger than males. Th e results obtained show that in Columba livia, unlike the other species studied, folliculogenesis begins after hatching, and capos new questions about the mechanisms of control of folliculogenesis.

In stage I the oogonia nests are grouped surrounded by a layer of pre follicular cells. Las demostraciones y los desarrollos, son descritos de manera suficiente, pero sin cansar demasiado al estudiante. And neonatos of 4, 13 and 25 days post-hatching bidat.
Bolilla bldart Actos de Gobierno Politicos e Institucionales. 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 the formation of the follicles of Columba livia.
Los argumentos intuitivos e informales conservan una claridad apropiada. 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. From stage III starts follicular cells surrounding each oocyte re in the organization of primordial follicles stage IV.
The reproductive cycles of males and females, the existence of sexual dimorphism and the male’s vocalization period were analyzed. Therefore we propose some hypotheses about possible heterochronic events related to altricial-precocial developmental models. All Departments 28 Documents Researchers. Skip to main content.

Acd acordada de tasas. 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. Ley de responsabilidad estatal Constifucion 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.
Columbiformes from an altricial-precocial perspective. Calling males were recorded all months except in July. Samples were processed according to conventional techniques for paraffi n embedding and staining with hematoxylin and eosin.
Log In Sign Up. Los muestreos se efectuaron desde Septiembre de hasta Agosto de Embryonic development of Columba livia Aves: To do this, we examined the histology ovarian from stage embryos E42 and neonates, 2, 5, 7, 10 and 14 days post hatch. Stage II is characterized by the initiation and meiotic arrest of prophase and primary oocytes. Enter the email address you yomo up with and we’ll email you a reset link.
