Abstract: Professor Pierre Blier -Seeking the secret of longevity, deep
in the sea.  Delineating the physiological and biochemical causes of
aging process in the animal kingdom is a highly active area of research
not only because of potential benefits for human health but also because
aging process is related to life history strategies (growth and
reproduction) and to responses of organisms to environmental conditions
and stress. In this presentation, I advocate studying bivalve species as
models for revealing the determinants of species divergences in maximal
longevity. This taxonomic group includes the longest living metazoan on
earth (Arctica islandica), which insures the widest range of maximum
life span when shorter living species are also included in the
comparative model. This model can also be useful for uncovering factors
modulating the pace of aging in given species by taking advantages of
the wide disparity of lifespan among different populations of the same
species. For example, maximal lifespan in different populations of A
islandica range from approximately 36 years to over 500 years. In the
last 15 years, research has revealed that either regulation or tolerance
to oxidative stress is tightly correlated to longevity in this group
which support further investigations on this taxon to unveil putative
mechanistic links between Reactive Oxygen Species and aging process.

Bio: Pierre Blier is Professor of Evolutionary Physiology at the
Université du Québec à Rimouski in Canada.  He obtained a PhD
at Laval University in Comparative Physiology and Biochemistry and has
been invited professor at the Scripps Institution of Oceanography, the
“Institution des Sciences de l’Évolution de Montpelleir and at
the Linus Pauling Institute of Science.   He is currently invited
Scholar at Monash University. He has been interested in the evolution of
mitochondria in animals (mostly ectotherms) for the last 30 years and
worked on the links between evolution of mtDNA and mitochondrial
phenotype.  In the last 15 years he studied the mitochondrial characters
potentially associated with lifespan animals.
