Effects on WAP coastal systems:
air warming -> glacier melting -> rock erosion at glacier underside

Long life expectancy in polar animals Cell respiration is maintained over age
Antarctic molluscs
maintain high levels of cellular antioxidants to prevent free radical damage of cells and chromosoms. They age slowlyand maintain their mitochondria intact over lifetime.
We investigate HOW they do that.

clicOPEN: cooperation network for young scientists
Student work and study in multi-national teams.
They have access to a wide range of expertise, improve language skills, and widen their horizon in many ways……
Network supports student

and organization.
