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…
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…
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…
Permanganate Oxidation of Anethole
"The oxidation of the carbon-carbon double bond in anethole by potassium permanganate can produce different yields of products depending on the reaction conditions. Conditions such as pH, reaction time, choice of phase transfer catalyst (PTC), PTC…
Strength of Imprinting in Ducks
"Hess (1958) demonstrated that as a duckling expended more energy to follow an object, a stronger imprinting bond would be formed. Hess drew his conclusion by testing ducklings that were imprinted to a decoy. During his experiments, the ducklings had…
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…
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…
Relative Preference of House Mice for Soybeans, Corn and Wheat
"Seven reproductively active male house mice (Mus musculus) were tested to determine their relative preference for soybeans (Glycine max), corn (Zea mays) and wheat (Triticum aestivum). Controls were established to minimize or stabilize the influence…
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…
Assessment of Mussel Populations in Lake St. Clair, Michigan
The purpose of this study was to determine the density of mussels on the floor of Lake St. Clair, Michigan and compare the data to a previous study conducted by Thomas Nalepa in 1992. SCUBA gear was utilized to reach the lake floor in order to…
