The underwater environment of the Antarctic dry valley lakes is an              exception to the usual paradigm concerning the light regime of                  planktonic microalgae.  In most ecosystems, phytoplankton                       experience light variability on a range of time scales related to               the vertical mixing rate.  In the permanently ice-covered dry                   valley lakes, it is hypothesized that a hydraulically stable water              column results in extreme constancy of light intensity and                      spectral quality.  This project will characterize the                           photophysiology of distinct phytoplankton populations in Lake                   Fryxell with respect to the non-fluctuating physical regimes.  The              research will examine the stability of the physical environment,                habitat preferences for distinct vertically stratified                          populations, time kinetics of photoadaptation, diel rhythmicy of                photosynthesis and the physiological mechanism responsible for                  observed photosynthesis versus irradiance patterns.  Since these                populations are relatively stable in space, they will provide a                 model system for studying photoadaptation as it occurs over the                 growing season.
