Taxonomic and ecological characterization of chrysophyte stomatocysts from northwestern Canada
Chrysophyte stomatocysts from the surface sediments of 49 lakes located on a north–south transect in the Yukon and Northwest Territories, Canada, were investigated for their potential use as indicators of environmental change in northern latitudes. Photographic plates and descriptions, following Int...
