Resumo

JANEIRO-CINQUINI, Thélia R. F.. Annual variation of the reproductive system in females of Bothrops jararaca (Serpentes, Viperidae). Iheringia, Sér. Zool. [online]. 2004, vol.94, n.3, pp.325-328. ISSN 0073-4721.  http://dx.doi.org/10.1590/S0073-47212004000300017.

The morphological changes of the ovary and oviduct of 238 tropical snakes Bothrops jararaca (Wied, 1824) were determined. The ovarian mass presented a remarkable decrease in October, after ovulation, staying in low levels from November to March, during the gestational period. From April to September, it increased because of the ovarian follicles maturation. A gradual increase in oviduct weight was observed from October to March due to stages of embryonic development. A significant difference was observed between right and left ovary weight, and oviduct length, independently of the months considered.

Palavras-chave : Bothrops jararaca; reproduction; ovary weight; oviduct length.
