Biology Of Chrysemys Picta Bellii In Southwestern Minnesota, Carl H. Ernst, Evelyn M. Ernst
Journal of the Minnesota Academy of Science
The turtle, Chrysemys picta belIii, was studied in southwestern Minnesota. The taxonomic characteristics are analyzed. The turtles are diurnal and have an annual activity period extending from mid-May to October. Activity and feeding are controlled by water temperature. The population dynamics are discussed. Growth is rapid early in life but slows after maturity. Growth is compared with that of other subspecies of C. picta. Habitat preferences, predation, parasites, algal relationships and shell abnormalities are discussed.
Rest Site Selection By Radio-Tagged Raccoons, Jay H. Schnell
Rest Site Selection By Radio-Tagged Raccoons, Jay H. Schnell
Journal of the Minnesota Academy of Science
Daytime resting sites and behavior of 14 radio-tagged raccoons were studied from April 18 to November 27, 1965, with types and use of the sites, daytime activity and shifts at the sites, and approach movements previous to resting being analyzed. The radio system pinpointed 173 rest sites, 7 4 per cent in swamps, 17 per cent in hollow trees, and 9 per cent in squirrel or bird nests. Use of the rest sites did not correlate with habitat type or size of the home range or with distances which animals traveled during their active nightly period. Behavioral influences in selection …
