TL;DR: The birth of a Y chromosome present in the Atlantic herring is reconstructed and the candidate male-determining gene BMPR1BBY encodes a truncated form of a BMP1B receptor, which originated by gene duplication and translocation and underwent rapid protein evolution.
Journal ArticleDOI
Effect of 17β-estradiol and progesterone on vitellogenesis in the spotted ray Torpedo marmorata Risso 1810 (Elasmobranchii: Torpediniformes): Studies on females and on estrogen-treated males
Prisco Marina,Valiante Salvatore,Maddalena Di Fiore Maria,Raucci Franca,Del Giudice Giuseppina,Romano Maurizio,Laforgia Vincenza,Limatola Ermelinda,Andreuccetti Piero +8 more
TL;DR: It is demonstrated that in Torpedo vitellogenin synthesis, as in other vertebrates, is under the control of E(2) but also that this synthesis is probably under the controlled of progesterone.
Journal ArticleDOI
Construction of a genetic map and development of DNA markers linked to the sex-determining locus in the Patagonian pejerrey (Odontesthes hatcheri).
TL;DR: A AFLP marker tightly linked to the sex-determining locus provides genetic confirmation that the sex of Patagonian pejerrey is determined genetically and would be useful for the analysis of the molecular basis of GSD and TSD in this species.
Journal ArticleDOI
Assessment of urine and fecal testosterone metabolite excretion in Chinchilla lanigera males.
TL;DR: Results of the present study indicate that the procedure used is a reliable and non-invasive method to repeatedly monitor variations in testicular endocrine activity in this species.
Journal ArticleDOI
Masculinized otoacoustic emissions in female spotted hyenas (Crocuta crocuta)
TL;DR: Prenatal androgen exposure apparently does affect OAEs, but the effects appear to be greater for the reflection-based cochlear mechanism that underlies CEOAEs than for the nonlinear co chlear mechanism underlying DPOAEs.

Book ChapterDOI
Seasonal breeding:nature's contraceptive.
G A Lincoln,Roger V. Short +1 more
TL;DR: The seasonal cycle highlights the seasonal changes in daylight length, rutting behavior, testicular diameter, sexual skin flush, and concentrations of plasma follicle-stimulating hormone, prolactin, and testosterone in a group of rams throughout the year.
Journal ArticleDOI
The physiological responses of anovulatory ewes to the introduction of rams: a review.
TL;DR: Ewes of many breeds can be stimulated to ovulate by the reintroduction of rams and appear to be effected both through a delay in the onset of the LH surge and through a direct action of progesterone on the ovary.
Journal ArticleDOI
Factors affecting the secretion of luteinizing hormone in the ewe.
TL;DR: LH is secreted as discrete pulses throughout all stages of the reproductive cycle of the ewe, including pre‐pubertal, seasonal and lactational anoestrus, and the luteal and follicular phases of the oestrous cycle.
Nutritional influences on reproduction in mature male sheep and goats
TL;DR: In this article, it was shown that nutritional signals exert powerful effects on the reproductive system of mature male ruminants, and the responses are partly independent of changes in gonadotrophin secretion.
