Egg perivitelline fluid proteome of a freshwater snail: Insight into the transition from aquatic to terrestrial egg deposition
(John Wiley & Sons Ltd, 2019-10-28)
Rationale: Proteins from the egg perivitelline fluid (PVF) are assumed to play critical roles in embryonic development, but for many groups of animals their identities remain unknown. Identifying egg PVF proteins is a ...

Carrying eggs in a semi-terrestrial environment: Physiological responses to water deprivation of mothers and embryos of the tree-climbing crab Aratus pisonii
(2021-07-01)
In semi-terrestrial crustaceans, mothers and the carried embryos form a unit. The ideal conditions for embryonic development place a sustained demand on the mothers' energy budget. A particular challenge for this unit is ...
Secretory cycle of the Dufour's gland in workers of the bumble bee Bombus terrestris L-(Hymenoptera : Apidae, Bombini)
(Brill Academic Publishers, 1999-08-01)
The Dufour's gland of Bombus terrestris workers, of different ages and with varying degrees of ovary development, was studied with the aim to verify its involvement in reproduction. Measurements of the diameter and the ...

Egg clutch dehydration induces early hatching in red-eyed treefrogs, Agalychnis callidryas
(PeerJ, 2017-07)
Terrestrial eggs have evolved repeatedly in tropical anurans exposing embryos to the new threat of dehydration. Red-eyed treefrogs, Agalychnis callidryas, lay eggs on plants over water. Maternally provided water allows ...
Testicular histology of Anurans that deposit eggs out of the water
(Fundación Miguel Lillo, 2020-12)
Anuran amphibians show the largest diversity of amphibian reproductive modes,many of which imply egg deposition out of the water. This kind of egg depositionrequires specialisations to avoid egg desiccation. Physiological, ...
Trophic eggs in the foam nests of Leptodactylus labyrinthicus (Anura, Leptodactylidae): An experimental approach
(2005-10-01)
The South American pepper frog, Leptodactylus labyrinthicus, is a large species that lays eggs in foam nests in holes dug out of the banks of different bodies of water. Recently, it was reported that only 6-10% of eggs are ...
