Description

Article written by James R. Erickson regarding mayfly habitats in bodies of water near Winona, Minnesota. Bodies of water surveyed and sampled: Lake Winona, the Gravel Pit (man-made lake), and Crooked Slough. Cal Fremling is cited for previous research on mayflies and for his screened pail sifter article. Erickson is credited as: "B.S., Biology, 1961; M.S., emphasis in zoology, 1962; from Winona State College. Currently teaching biology [Mounds View High School, St. Paul, Minnesota]." Abstract/summary: "Three small lakes near Winona, Minnesota, were sampled to determine if they supported populations of Hexagenia mayfly nymphs. Hexagenia nymphs were rare in Lake Winona and the Gravel Pit, and none was found in Crooked Slough. A low dissolved oxygen content at the mud-water interface is probably the limiting factor in Lake Winona and Crooked Slough. The limiting factor in the Gravel Pit is probably the bottom type." Article reprinted from the Journal of the Minnesota Academy of Science, volume 32, number 1, 1964. Part of the Cal R. Fremling Collection.
