A Small Mammal Survey of the Vermilion Ecological Study Area
A small mammal survey was conducted at the Vermilion Ecological Study Area from 1-June to 13-August, 1987. Snap, live, and pitfall traps were placed in each of three habitat types: dunes; woods; and wetlands. Three trapping periods were made and…
A Winter Survey for Oxygen and Temperature in McNearney Lake, Chippewa County, Michigan
McNearney Lake was hypothesized to be a winter-kill lake because two populations of fish planted in the fall could not be detected in the spring. The gavimetric cell oxygen analyzer was used to check for oxygen and temperature.
Four test points were…

Aggregation Patterns of Green Frog Tadpoles in Relation to Temperature and Depth
"A small pond in Ottawa County, MI, was studied to determine if a correlation existed between aggregation patterns of Green frog tadpoles (Rana clamitans) and temperature or depth. Sampling took place from May 26 to July 4 at varying times throughout…

Biodegradation of Atrazine in a Sandy Loam Soil
The herbicide, Atrazine, was applied to a sandy loam soil at concentrations of Oppm, lOppm, lOOppm, and 500ppm.
The treated samples were maintained at 28°±2°C for a period of 6 weeks. At 2 week intervals the samples were plated out to obtain the…

Chemotaxis in Escherichia to D-Galactose
The chemotactic response to D-galactose by a wild strain of Escherichia coli was studied for E. coli cultured in nutrient broth and E. coli cultured in Rogosa's synthetic medium. The effect of enrichment of these media with D-L-methionine was…
Correlation of Changes in Song Repertoire of the Male Yellow Warbler with Specific Periods of Nesting
The nesting behavior and song repertoire cornposition of a pair of yellow warblers (Dendroica petechia) was studied in Sault Ste. Marie, Michigan during the 1982 nesting season. The songs of one male were recorded using a variable speed tape recorder…
Electornmicrographic Study of the Morphological Malformations Caused By Benzoyl Ureas Upon the Eastern Spruce Budworm
The scope of this project was to generate and document the morphological malformations caused by either of two benzoyl ureas (Dimilin and UC 62644), upon the fourth, fifth, and sixth instars of-the eastern Spruce budworm (Choristonurea fumiferana…
Foraging Differences Between Male and Female Piping Plovers
Data was collected along the Lake Superior Shore between May and October 1986 from Piping Plovers (Charadrius melodus) of Known sex, to determine their foraging patterns and strategies. Statistical analysis of the data revealed that male Piping…
Hair Color Variation of Adult Gray Squirrels in Winter Pelage
A study was conducted on hair samples taken from 15 gray squirrels (Sciurus carolinensis). These samples were obtained from 8 specific points on the squirrel's body and the banding pattern was noted. The results indicated that in the lateral rump…
