Oviparity or viviparity? That is the question…
Reproductive Biology, 2012The modes of reproduction undoubtedly represent one of the most critical life-history traits because they profoundly affect fitness and survival. The parent-offspring conflict over the degree of parental investment may be the main selective factor in the evolution of reproduction.

Internal Fertilization in an Oviparous Frog
Science, 1981Eleutherodactylus coqui , an oviparous frog, undergoes internal fertilization. If this mode of fertilization occurs in other species of anurans, interpretations of anuran reproductive strategies based on the assumption of external fertilization must be reviewed.

Heritability and developmental plasticity of growth in an oviparous lizard
Heredity, 2022Selective processes act on phenotypic variation yet the evolutionary potential of any given trait relies on underlying heritable variation. Developmental plasticity is an important source of phenotypic variation, but it can also promote changes in heritability by modifying environmental sources of variability.

The reproductive cycles of the oviparous lizards
Amphibia-Reptilia, 1996Abstract We examined the reproductive cycles of two species of the only oviparous genus Platysaurus in the predominantly viviparous family Cordylidae, endemic to Southern Africa. The reproductive cycles of Platysaurus capensis and P.

Oviposition Cycle in the Oviparous Fish Xenopoecilus sarasinorum
Zoological Science, 2007To clarify the reproduction of the oviparous teleost Xenopoecilus sarasinorum, changes in oocyte composition and oviposition cycle were investigated. After release, a batch of spawned eggs hung from the urogenital pore by attaching filaments (36.3+/-0.8 in number, n=31; about 4.3-7.8 mm in length, 5-8 microm in diameter) on the chorion (egg envelope ...

Oviparity in Littorina saxatilis (Olivi)
Nature, 1947It has always been believed in the past that all the sub-species and varieties ascribed to Littorina saxatilis (Olivi)1 are viviparous. Contrary to this, it has now been observed that some of these reproduce very much like L. littoralis (L.) by means of gelatinous egg masses2.
