MABUYA HEATHI PDF

New World skinks of the genus Mabuya exhibit a unique form of viviparity that involves ovulation of tiny 1 mm eggs and provision of virtually all of the nutrients for embryonic development by placental means. Studies of the Brazilian species M. The uterine lining is intimately apposed to the chorioallantois, with no trace of an intervening shell membrane or of epithelial erosion; thus, the placenta is epitheliochorial. The uterus exhibits multicellular glands that secrete organic material into the uterine lumen.

Brasiliscincus heathi (Schmidt & Inger, 1951)

Ovulation occurs during October—January, rapid growth in embryos takes place during June—October, and parturition occurs in September—November, between 9 and 12 months after ovulation. Female and male reproduction is cyclic and is synchronous between the sexes. Brood size is 2—9 and is significantly correlated to female size. Fat bodies of females are largest when embryos are small, and decrease in mass as embryos increase in size. Testes in males are largest during September—February, associated with a decrease in fat body size. Mabuya heathi is the second species of lizard in the caatinga herpetofauna shown to be strongly cyclical in reproduction and to reproduce only once per year.
