Evidence for cell turnover as the mechanism responsible for the transport of embryos towards the vagina in viviparous onychophorans (velvet worms)

open access: yesFrontiers in Zoology, 2019
Background Onychophorans, commonly known as velvet worms, display a remarkable diversity of reproductive strategies including oviparity, and placentotrophic, lecithotrophic, matrotrophic or combined lecithotrophic/matrotrophic viviparity.

Shell Constraints on Evolutionary Body Size–Limb Size Allometry Can Explain Morphological Conservatism in the Turtle Body Plan

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
Turtle body size and limb size scale nearly isometrically along the group's evolution, although major deviations are only seen in highly specialized ecological or morphological groups. The evolution of the shell constrained turtle body proportions, as they show lower rates of variance accumulation in these allometries than other more diverse and ...

Snake reproduction – ovipary, vivipary and ovovivipary [PDF]

open access: yes, 2019
Zmije su vrlo raznolika i široko rasprostranjena skupina životinja. Nastanjuju raznolika staništa, što zahtjeva specifične prilagodbe. Kao i za niz drugih aktivnosti, morale su razviti prilagodbe za razmnožavanje.
