Are thyroid hormones mediators of incubation temperature-induced phenotypes in birds?
Incubation temperature influences a suite of traits in avian offspring. However, the mechanisms underlying expression of these phenotypes are unknown. Given the importance of thyroid hormones in orchestrating developmental processes, we hypothesized that they may act as an upstream mechanism mediating the effects of temperature on hatchling phenotypic traits such as growth and thermoregulation....
متن کاملEcological, evolutionary, and conservation implications of incubation temperature-dependent phenotypes in birds.
Incubation is a vital component of reproduction and parental care in birds. Maintaining temperatures within a narrow range is necessary for embryonic development and hatching of young, and exposure to both high and low temperatures can be lethal to embryos. Although it is widely recognized that temperature is important for hatching success, little is known about how variation in incubation temp...
متن کاملEffect of experimentally induced subchronic selenosis on thyroid hormones and biochemical indices in calves
The present investigation was performed to determine the effect of long-term administration of sodium selenite on the biochemical indices and concentration of thyroid hormones in calves. Sodium selenite solution was drenched at 0.1 and 0.25 mg per kg body weight for 12 weeks. Higher dose produced characteristic symptoms of selenosis whereas mild symptoms were observed with lower dose. The toxic...
متن کاملChanges in Blood Levels of Thyroid Hormones in Two Species of Passerine Birds
-Annual changes in plasma levels of thyroxine (T4) and triiodothyronine (T3) were compared in White-crowned Sparrows (Zonotrichia leucophrys gumbeliz) and House Sparrows (Passer domesticus) using serial blood samples from birds maintained in outdoor aviaries and from feral birds. Gonadal size was monitored by monthly laparotomy, and plumage was examined for molt at frequent intervals. Hormone l...
متن کاملEvaluation of thyroid hormones in patients with lead poisoning
Background: Each toxic agent results in unique presentations, depending on what neurophysiological changes occur following exposure. Scientific understanding of lead toxicity in the organ systems and at low levels of exposure continues to evolve. However, effects of lead poisoning on the thyroid gland function are controversial. In this descriptive study, changes in thyroid hormones in patients...
