Abstract

Kinosternon scorpioides, popularly known as scorpion mud turtle (jurará in Brazil), is a fresh water species. There is little information about its reproduction and the present study aims to morphologically characterize the reproductive organs of male K.scorpioides bred in captivity in two seasons of the year. The reproductive tracts of adult animals under went macroscopic ultrastructural analysis of the lumen, as well as scanning electron and transmission microscopy. Macroscopically, the male genital organs consist of a pair of testicles, epididymis, the vas deferens and a penis. Testicles, epididymis and deferents ducts were characterized by reproductive activity during the rainy season and reproductive inactivity in the dry period. The morphometry regarding the tubular and luminal diameter and epithelial height of the testicles, epididymis and deferents ducts showed changes along the studied periods. The rainy season presented higher averages than the dry period. The penis did not show any changes during both periods. It was concluded that K. scorpioides exhibits reproductive seasonality.

摘要

黄缘闭壳龟，俗称蝎子泥龟（巴西的 jurará），是一种淡水物种。关于它的繁殖，目前的研究旨在从形态学上描述在一年中的两个季节在圈养环境中繁殖的雄性 K.scorpioides 的生殖器官。成年动物的生殖道进行了管腔的宏观超微结构分析，以及扫描电子显微镜和透射电子显微镜分析。宏观上，雄性生殖器包括一对睾丸、附睾、输精管和阴茎。睾丸、附睾和输精管在雨季表现出生殖活动，而在旱季则没有生殖活动。睾丸、附睾和输精管的管状和管腔直径以及上皮高度的形态测量学在研究期间发生了变化。雨季的平均值高于旱季。阴茎在两个时期都没有任何变化。研究结果表明，黄缘闭壳龟具有生殖季节性。
