Abstract:The perennially ice-covered Lake Bonney in Antarctica has been deemed a natural laboratory for studying life at the extreme. Photosynthetic algae dominate the lake food webs and are adapted to a multitude of extreme conditions including perpetual shading even at the height of the austral summer. Here we examine how the unique light environment in Lake Bonney influences the physiology of twoChlamydomonasspecies.Chlamydomonas priscuiiis found exclusively in the deep photic zone where is receives very low light l… Show more
