Testing the short-and long-term effects of elevated prenatal exposure to different forms of thyroid hormones.

ABSTRACT: Maternal thyroid hormones (THs) are known to be crucial in embryonic development in humans, but their influence on other, especially wild, animals remains poorly understood. So far, the studies that experimentally investigated the consequences of maternal THs focused on short-term effects, while early organisational effects with long-term consequences, as shown for other prenatal hormones, could also be expected. In this study, we aimed at investigating both the short- and long-term effects of prenatal THs in a bird species, the Japanese quail Coturnix japonica. We experimentally elevated yolk TH content (the prohormone T₄, and its active metabolite T₃, as well as a combination of both hormones). We analysed hatching success, embryonic development, offspring gr
