Two hypotheses have prevailed to explain the evolution of viviparity in reptiles: the first proposed that viviparity evolved in response to cold-climates because the possibility of pregnant females to thermoregulate at ...
Reproductive histology of Tomeurus Gracilis Eigenmann, 1909 (teleostei: atherinomorpha: poeciliidae) with comments on evolution of viviparity in Atherinomorph fishes
(Wiley-liss, Div John Wiley & Sons Inc, 2010-11)
Tomeurus gracilis is a species long considered pivotal in understanding the evolution of livebearing in atherinomorph fishes. Tomeurus gracilis is a zygoparous or embryoparous poeciliid: internal fertilization is followed ...
Energy allocation to growth and reproduction in a viviparous lizard endemic to the highlands of the Andes, Argentina
(Wiley, 2015-09)
Individuals devote energy intake to growth, maintenance and reproduction, so knowing the way in which they allocate this energy between competing demands is essential to understand their relationship with the environment. ...
Structure of the gonoduct of the viviparous teleost Cnesterodon decemmaculatus (Jenyns, 1842) (Poeciliidae)
(Wiley-liss, div John Wiley & Sons Inc., 2021-04)
During embryogenesis, teleost females do not develop Müllerian ducts, which form the oviducts in all other vertebrates. Thus, when they reach sexual maturity they do not have oviducts. In viviparous teleosts, the lack of ...
Observations on parturition in two Liolaemus species of the archeforus group (Iguania: Squamata: Liolaemidae)
(Societas Europaea Herpetologica, 2010-12)
The viviparous reproductive mode is very common among iguanian lizards of the genus Liolaemus, where viviparity occurs in almost half of all species. However, detailed observations about parturition are only available for ...
