The influence of larval growth history and exogenous thyroid hormone on life history allocation patterns in the axolotl (Ambystoma mexicanum).(COMMUNICATIONS--UNDERGRADUATE)(Technical report)
Apr 01, 2008; ... In vertebrates, growth and development are interacting systems that are regulated at different points along the hypothalamus-pituitary-thyroid axis (1,2). Amphibian metamorphosis is an excellent system for studying hormone-mediated interactions because of the ease of manipulating ...
