DOI: 10.1002/jmor.21566
Abstract: The main evolutionary milestone in the oviparity–viviparity transition is placentation. The placenta is an organ with great morphological diversity among eutherians. The expression of different glycosidic residues (Gr) in the near‐term placenta constitutes its glycotype.… read more here.

DOI: 10.1080/08912963.2015.1124873
Abstract: Abstract Microvertebrates are a major component of many assemblages recovered from the Quaternary of the Argentine Pampas. The main goal of this paper is to analyse the taphonomic history of a Holocene microfossil bonebed, recovered… read more here.

DOI: 10.1080/08912963.2017.1374957
Abstract: Abstract The Plains vizcacha (Lagostomus maximus) is one of the largest rodents in South America. They live in communal burrow systems (vizcacheras) shaped by complex subterranean galleries which produce a strong impact on the local… read more here.

DOI: 10.1111/rda.13333
Abstract: This study reports the histochemistry and the distribution of glycoconjugates (GCs) in the zona pellucida (ZP) of preantral, secondary, tertiary, polyovulatory and atretic follicles of ovaries from non-pregnant (NPr) and pregnant (Pr) females of Lagostomus… read more here.

The balance between apoptosis and autophagy regulates testis regression and recrudescence in the seasonal-breeding South American plains vizcacha, Lagostomus maximus

DOI: 10.1371/journal.pone.0191126
Abstract: Mammalian testis undergoes deep changes in their architecture and function during photoregression conditions in seasonal breeders. Particularly, the testicular mechanisms that regulate the transition between the active (functional) and inactive (regression) stage vary between species.… read more here.

Local production of neurostradiol affects gonadotropin‐releasing hormone (GnRH) secretion at mid‐gestation in Lagostomus maximus (Rodentia, Caviomorpha)
Sign Up to like & getrecommendations! Published in 2017 at "Physiological Reports"
DOI: 10.14814/phy2.13439
Abstract: Females of the South American plains vizcacha, Lagostomus maximus, show peculiar reproductive features such as massive polyovulation up to 800 oocytes per estrous cycle and an ovulatory process around mid‐gestation arising from the reactivation of… read more here.
