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 slowly

and 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

exchange btw. labs and countries Young scientists are involved in scientific planning meetings

and organization.

Last clicOPEN workshop in Bremerhaven, Germany in Oct 2006
