Energy conservation is a key priority for organisms having to face seasonal or stochastic shortages in resource supplies.

In this seminar, Damien will discuss how bioenergetics analysis of oxidative tissues  (liver and skeletal muscles) from fasted birds revealed the development of thrifty mitochondria, alleviating the needs for nutrients to synthesize ATP and fulfil cellular energy needs.

This upregulation of mitochondrial  ATP efficiency is flexible, being fully reversed by refeeding or by thyroid hormones.
