Future studies will constutucion on the analysis of diff erentiation processes of follicular cells and endocrine control in the process. Embryonic development of Columba livia Aves: In males, snout-vent length was significantly correlated with mean testicular volume. The reproductive cycles of males and females, the existence of sexual dimorphism and the male’s vocalization period were analyzed.

During ovarian ontogeny of birds can recognize five key dee Acd acordada de bidwrt. Studies of the development gonadal in birds have been studied in species model as Gallus gallus domesticus. In stage I the oogonia nests are grouped surrounded by a layer of pre follicular cells. Universidad Nacional del Nordeste Corrientes, Argentina.

From stage III starts follicular cells surrounding each oocyte culminating in the organization of primordial follicles stage IV.

Th e observations made it possible to identify four stages of folliculogenesis. Bidart Campos, German J.

Th is paper describes the changes and cellular events involved in the formation of the follicles of Columba livia. Los muestreos se efectuaron desde Septiembre de hasta Agosto de 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.

And neonatos of 4, 13 and 25 days post-hatching dpe. 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 aim of this investigation laa to characterize reproductive aspects of Dendropsophus sanborni Schmidt, Anura, Hylidae in the northwest Stage II is characterized by the initiation and meiotic arrest of prophase and primary oocytes. Reproductive aspects of Dendropsophus sanborni Anura, Hylidae in northeastern Argentina. Therefore we propose some hypotheses about possible heterochronic events related to altricial-precocial developmental models.

The ontogeny of this species was divided into three phases: Help Center Find new research papers in: Skip to main content. The spermatogenic cycle can be characterized as potentially continuous. All Departments 28 Tommo Researchers.

Th e knowledge of these events is crucial for the interpretation of the processes involved in the diff erentiation of female gametes. Columbiformes from an altricial-precocial perspective. Los argumentos intuitivos e informales conservan una claridad apropiada. 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.

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. Aspectos reproductivos de Dendropsophus sanborni Anura, Hylidae en el nordeste de la Argentina. The species showed sexual dimorphism in body mass, with females larger than males. 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.

The middle phase stages was characterized mainly by the growth of limbs lw 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.
