Metamorphosis, classically defined as a spectacular post-embryonic transition, is well
exemplified by the transformation of a tadpole into a frog. It implies the appearance of new …

Thyroid hormones (THs) are well-known regulators of development and metabolism in
vertebrates. There is increasing evidence that THs are also involved in gonadal …

Glucocorticoids hormones (GC s) are intuitively important for mediation of age‐dependent
vertebrate life‐history transitions through their effects on ontogeny alongside underpinning …

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 …

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

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

Many amphibian species exploit temporary or even ephemeral aquatic habitats for
reproduction by maximising larval growth under benign conditions but accelerating …

The environment experienced by developing organisms can shape the timing and character
of developmental processes, generating different phenotypes from the same genotype, each …

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

Developmental plasticity is found in most organisms, but its role in evolution remains
controversial. Environmentally induced phenotypic differences may be translated into …
