Symposium: Inside the black box: the mitochondrial basis of life-history variation and animal performance


Mitochondria play a critical role in determining animal performance. Mitochondria produce ATP molecules that fuel nearly all organismal processes, but also are responsible for the production of reactive oxygen species - and in turn oxidative stress - an important contributor to senescence. As a result, variation in mitochondrial properties between individual can predict differences in animal performance such as maintenance, growth, and reproduction. In addition, the genetic basis and in turn heredity of mitochondrial performance via the intricate interactions between mitochondria and nuclear genes coding for the mitochondrial proteins can advance our understanding of life history evolution. The integration oxidative stress, energetic capacity and efficiency of the mitochondria, and other variables related to their genetic basis is already beginning to provide very interesting insight, however, the theory and methods associated with this approaches remain unfamiliar to many ecologist and evolutionary biologist.

This session aims to bring investigators together to present their research and work toward building improved approaches to understanding the role of mitochondrial properties in variation among individual in life-history trajectory
