Dr. Jeffery R. Stone
Professor
Explores the response of freshwater diatoms to environmental change, whether driven by climate or anthropogenic forces. I typically use stratigraphic lake core studies, 3D lake modeling, and modern ecological information to reconstruct past lake or river settings. Recent research focus also includes exploration of diatom taxonomy and diversity in lake settings. Research topics range from millennial to seasonal in scale, and spans modern environments and throughout the Quaternary.
Dr. Karlyn S. Westover
Adjunct Professor
Specializing in statistical methods and diatom analyses in alpine settings. Current research projects in the US Midwest, eastern Africa, and Switzerland.
Research
Lakes in the Western US: Holocene drought history of the US Rocky Mountains, pollution history of Lake Couer d’Alene, Holocene paleoclimate recontruction of lakes in the Sierra Nevadas, Early Holocene climate evolution of the Greater Yellowstone Ecosystem, diatom taxonomy and evolution in the western US including Miocene-age diatomite deposits, three-dimensional lake modeling and lake level change.
Lakes in the US Midwest: anthropogenic impacts on lakes and wetlands of Indiana, environmental damage and resilience in the Wabash River ecosystem, spatiotemporal variability and drivers of east-west hydroclimate anti-phasing.
Lakes in eastern Africa: Pleistocene paleoclimate history of Lakes Malawi, Tanganyika, Turkana, paleolake Mababe, paleolake Hadar, and the diatomites of the Chemeron formation in the Baringo Basin, taxonomy and diversity of diatoms in eastern Africa, diatom diversity and evolution in the East African Rift Valley.
Lakes in Guatemala: marine incursions in the greater Lake Izabal ecosystem, tectonicallydrive eutrophication events reconstructed from diatoms in Lake Chichoj, Lake Atitlan, Lake Amatitlan, and Lake Ayarza.
