Endocrine control of Anguilla anguilla glass eel dispersal: effect of thyroid hormones on locomotor activity and rheotactic behavior
Dispersal, one of the most important processes in population ecology, is an issue linking physiological and behavioral features. However, the endocrine control of animal dispersal remains poorly understood. Here, we tested whether and how thyroid hormones may influence dispersal in glass eels of Ang...

Dispersal, one of the most important processes in population ecology, is an issue linking physiological and behavioral features.

Glass eels were caught during their estuarine migration and treated by immersion in either a l-thyroxine (T4) or a thiourea (TU) solution.
