Placenta: an old organ with new functions

Frontiers in Immunology
The transition from oviparity to viviparity and the establishment of feto-maternal communications introduced the placenta as the major anatomical site to provide nutrients, gases, and hormones to the developing fetus. The placenta has endocrine functions,

Gestation alters the gut microbiota of an oviparous lizard

FEMS Microbiology Ecology, 2019
ABSTRACTMammalian pregnancy can alter the diversity, membership and structure of the maternal gut microbiota, but it is unclear whether this phenomenon occurs in vertebrates with different reproductive strategies. We conducted 16S rRNA bacterial inventories to investigate whether oviparous lizards exhibit shifts in gut microbiota similar to those ...

Strong population genetic structure and contrasting demographic histories for the small-spotted catshark (Scyliorhinus canicula) in the Mediterranean Sea [PDF]

, 2014
Coastal and demersal chondrichthyans, such as the small-spotted catshark, are expected to exhibit genetic differentiation in areas of complex geomorphology like the Mediterranean Basin because of their limited dispersal ability.

Observations on the Nidamental Glands of Hydrolagus colliei, Raja rhina and Platyrhinoidis triseriatusi [PDF]

, 1948
A study of the reproductive system and the nature of the reproduction of the elasmobranchs was started by me in 1940, with the idea of finding out whether or not there is any correlation between the phylogeny and the reproductive structures and habits.
