Professor Davis will conduct analyses of pollen deposits to                determine how the climatic effects of the Sierra Nevada of eastern              California have changed from the last glacial maximum to the present.           The Sierra crest currently separates dryland vegetation to the east             from mesic forest vegetation to the west.  In the last glacial age the          boundary was not as sharp; vegetation was similar on both slopes of             the Sierra.  This project will examine the timing of vegetation changes         and will attempt to determine what combination of precipitation and             temperature changes produced the documented shift in vegetation                 patterns.  The results of this research will increase our understanding         of processes of climatic and vegetation change and the ways regional            changes are related to global changes.
