Resumo: Forty pairs of ovaries of mature female Peltocephalus dumerilianus (Schweigger 1812) were analyzed, to establish the morphologic monthly changes that take place during one year; we examined macroscopically the oviducts and the ovaries of specimens that the riverside inhabitants of the municipality of Barcelos, Amazons, Brazil, used for their consumption. We measured the diameter and recorded the number of enlarged ovarian follicles and corpora lutea. The results show the gradual enlargement of follicles in agreement with the reproductive period, observing that during the last third of the process; just before oviposition they become more evident. The positive relationship between the size of the female and the ovarian mass, is statistically significant (F (10.29)=3.655, p < 0.05). Follicullar sizes suggest that this species nests only once a year.

Se llevaron a cabo exámenes macroscópicos de los oviductos y de los ovarios de especímenes que los habitantes ribereños del municipio de Barcelos, Amazonas, Brasil, utilizaron para su consumo, usando metodológicamente la medida del diámetro y conteo de los folículos ováricos y de los cuerpos lúteos. Los resultados muestran la presencia gradual de folículos acorde con la época reproductiva, resaltando que durante el último tercio del proceso, justo antes de la postura se hacen más evidentes; se analiza la relación existente entre el tamaño de la hembra y la masa ovárica, la cual es estadísticamente significativa (F (10,29)=3,655, p < 0,05). Se hace evidente la existencia de una jerarquía ovario folicular que demuestra que para esta especie solo es posible fisiológicamente una postura por año.spaVolume 41, Número 2, Pags. 243-250Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessOvariesFolliclesReproductive CyclePeltocephalus DumerilianusBrazilCiclo ovárico y jerarquía folicular de Peltocephalus dumerilianus (Testudines: Podocnemididae)Ovarian cycle and follicular hierarchy of Peltocephalus dumerilianus (Testudines: Podocnemididae)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleActa Amazonicareponame:Repositório Institucional do INPAinstname:Instituto Nacional de Pesquisas da Amazônia (INPA)instacron:INPAORIGINALartigo-inpa.pdfapplication/pdf908701https://repositorio.inpa.gov.br/bitstream/1/13486/1/artigo-inpa.pdfa295530d36363bcdefcf5413db9df3ceMD51CC-LICENSElicense_rdfapplication/octet-stream914https://repositorio.inpa.gov.br/bitstream/1/13486/2/license_rdf4d2950bda3d176f570a9f8b328dfbbefMD521/134862020-07-14 09:59:17.455oai:repositorio:1/13486Repositório de PublicaçõesPUBhttps://repositorio.inpa.gov.br/oai/requestopendoar:2020-07-14T13:59:17Repositório Institucional do INPA - Instituto Nacional de Pesquisas da Amazônia (INPA)false
