Embryos of the viviparous dermapteran, Arixenia esau develop sequentially in two compartments: terminal ovarian follicles and the uterus.

open access: yesPLoS ONE, 2013
Three main reproductive strategies have been described among insects: most common oviparity, ovoviviparity and viviparity. In the latter strategy, the embryonic development takes place within the body of the mother which provides gas exchange and ...

Anatomy of the female reproductive system and sperm storage of the viviparous caecilian Typhlonectes natans (Gymnophiona: Typhlonectidae)

open access: yesActa Biologica, 2018
Here, we describe the anatomy of the female reproductive system of the aquatic, viviparous caecilian Typhlonectes natans. We conducted our research on two adult females using light microscopy and reflected our results with the available literature data ...

Hatching Strategies in Monogenean (Platyhelminth) Parasites that Facilitate Host Infection [PDF]

open access: yes, 2011
In parasites, environmental cues may influence hatching of eggs and enhance the success of infections. The two major endoparasitic groups of parasitic platyhelminths, cestodes (tapeworms) and digeneans (flukes), typically have high fecundity, infect more

Effects of maternal basking and food quantity during gestation provide evidence for the selective advantage of matrotrophy in a viviparous lizard. [PDF]

open access: yesPLoS ONE, 2012
The evolution of matrotrophy (i.e., direct supply of nutrients by the mother during gestation) may be associated with high maternal energy availability during gestation. However, we lack knowledge about the selective advantages of matrotrophic viviparity
