Ocorrência de híbridos não naturais entre Bothrops jararaca e B. neuwiedi (Serpentes, Viperidae)

In May 1987, a female of Bothrops jararaca (Wied, 1824), from Carazinho, Rio Grande do Sul (RS), Brazil, was placed in the same vivarium with a male of Bothrops neuwiedi Wagler, 1824 coming from Guaíba, RS. There, they stayed for aproximately ten months. In March 1988, it was observed a delivery of five live and two still born, among them six presented morphologic characteristics of B. neuwiedi and one of B. jararaca. After the female died, in April 1988, through necropsy, two fetusus were found, one near the cloaca and, both identified as B. neuwiedi. The morphologic analysis and the origin of the progenitors suggest the hypothesis that the litter was resulted of cross-breeding.

Variação anual do sistema reprodutor de fêmeas de Bothrops jararaca (Serpentes, Viperidae)

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.
