Palaeolimnological and palynological studies of lakes in Alberta and the central Cordillera of British Columbia. Specifically, research involves elucidating the late Quaternary history of selected lakes, and determining effects of inferred Holocene climate change upon these lakes and their communities through use of microfossils (pollen, diatoms, chrysophyte stomatocyst), pigments and geochemistry. Relationships between modern surficial sedimentary diatom and chrysophyte stomatocyst assemblages and measured environmental parameters are being investigated using multivariate approaches.
