Fish Movement Among Lakes: Are Lakes Isolated (2008)
Robert A. Daniels, Richard S. Morse, James W. Sutherland, Robert T. Bombard, Charles W. Boylen
The concept of a lake as an isolated unit is a central theme in research and management of freshwater systems. Support is based on direct observations of lake communities. Studies undertaken in the...
Madsen, John D., Smart, R. M., Eichler, Lawrence W., Boylen, Charles W., Sutherland, James W., Bloomfield, Jay A.
Onondaga Lake, located in upstate New York near Syracuse, has been heavily impacted by industrial and domestic effluent. Due to these impacts, the native littoral vegetation had largely disappeared....
Sheldon, Richard B., Boylen, Charles W.
A diatom-dominated population of epiphytic algae was studied in an oligotrophic lake to determine the factors which limit epiphyte growth and to measure their contribution to primary productivity....
Macromolecular Synthesis and Degradation in Arthrobacter During Periods of Nutrient Deprivation
Scherer, Carin G., Boylen, Charles W.
Cells of Arthrobacter atrocyaneus and A. crystallopoietes, harvested during their exponential phase, were starved in 0.03 M phosphate buffer (pH 7.0) for 28 days. During this time, the cells...
Collins, Carol D., Boylen, Charles W.
Cultures of Anabaena variabilis were exposed to different light intensities, and the time course of photoadaptation was measured by photosynthetic rate and changes in pigmentation. A shift down in...
Microbiological Survey of Adirondack Lakes with Various pH Values
Boylen, Charles W., Shick, Marcy O., Roberts, Deborah A., Singer, Robert
Nine high-altitude oligotrophic Adirondack lakes in upstate New York having water of pH 4.3 to 7.0 were surveyed for total bacterial numbers and possible adaptation of the microbial communities to...
Boylen, Charles W., Ensign, Jerald C.
Cells of Arthrobacter crystallopoietes, harvested during growth as spheres and as rods, were starved by shaking at 30 C in phosphate buffer for 30 days, during which time they maintained 100%...
Survival of Arthrobacter crystallopoietes During Prolonged Periods of Extreme Desiccation
Cells of Arthrobacter crystallopoietes mixed in sand and air-dried have survived for up to 6 months after an initial period in which approximately half the cells lost their viability. Comparative...
Boylen, Charles W., Ensign, Jerald C.
Cell walls were isolated from cells of Bacillus subtilis strain Marburg during synchronous outgrowth of spores, during the two synchronous cell divisions which followed, and at various times during...
Tison, David L., Pope, Daniel H., Boylen, Charles W.
Temperature optima for the heterotrophic utilization of glucose and an amino acid mixture were determined throughout the year in sediments from Lake George, N.Y. The temperature optimum decreased...
Installation and Use of the Microscope Within a Gastight Glove Box
The adaptation of a high-resolution phase-contrast microscope for glove box use, which allows the stage and focusing knobs in the glovebox, although oculars and camera remain outside, is described.

Bacterial Community Structure of Acid-Impacted Lakes: What Controls Diversity?▿ †
Percent, Sascha F., Frischer, Marc E., Vescio, Paul A., Duffy, Ellen B., Milano, Vincenzo, McLellan, Maggie, ...
Although it is recognized that acidification of freshwater systems results in decreased overall species richness of plants and animals, little is known about the response of aquatic microbial...
