JF Gudernatsch, an anatomist at Cornell Medical School, traveled by ship to the Naples
Zoological Station in the summer of 1910. He took along various mammalian organs …

The current review focuses on the molecular mechanisms and developmental roles of
thyroid hormone receptors (TRs) in gene regulation and metamorphosis in Xenopus laevis …

Over the past decade, advances in both molecular developmental biology and evolutionary
ecology have made possible a new understanding of organisms as dynamic systems …

Life history theory seeks to explain the evolution of the major features of life cycles by
analyzing the ecological factors that shape age-specific schedules of growth, reproduction …

We investigated whether exposure to environmentally relevant concentrations of the
bactericidal agent, triclosan, induces changes in the thyroid hormone-mediated process of …

Thyroid hormone (TH) regulates diverse developmental events and can drive disparate
cellular outcomes. In zebrafish, TH has opposite effects on neural crest derived pigment …

Background Chronic exposure to excess arsenic in drinking water has been strongly
associated with increased risks of multiple cancers, diabetes, heart disease, and …

Publisher Summary Amphibians exhibit considerable diversity in behavioral, physiological,
and life history strategies. They are geographically widespread, occupying a diverse range …

In multicellular organisms, development is based in part on the integration of communication
systems. Two neuroendocrine axes, the hypothalamic–pituitary–thyroid and the …

Thyroid hormone induces the complete metamorphosis of anuran tadpoles into juvenile
frogs. Arguably, anuran metamorphosis is the most dramatic effect of a hormone in any …
