UV-B radiation screen and the respiratory potential (terminal elec­ tron transport system - ETS activity) were investigated in phytoplankton from five mountain lakes located on an elevation gradient from 1383 m to 2150 m a.s.l.. The amount of UV absorbing compounds inphytoplankton was generally higher on the lakes from higher elevation. The increased ETS activity of phytoplankton in high­ er lakes wassuggested to reflect the energetic cost of generating the internal mech­ anisms for photoprotection.
