Range And Optimum Growth Concentrations Of Phosphate And Nitrate For Chlamydomonas Reinhardtii, Thomas E. Hill
Range And Optimum Growth Concentrations Of Phosphate And Nitrate For Chlamydomonas Reinhardtii, Thomas E. Hill
Masters Theses
A study was conducted on the alga Chlamydomonas reinhardtii to determine the range and optimum growth concentrations of phosphate and nitrate. There are only a few species of algae for which this type of data is known. Inorganic nutritional data is basic to the understanding of the complexities of phytoplankton ecology and eutrophication.
The "plus" strain of this heterothallic alga was cultured in a TRIS-buffered inorganic medium with various concentrations of sodium phosphate and potassium nitrate and adjusted to a pH of 7.4. The axenic cultures were evaluated at the end of 6 days with a spectrophotometer, at a wavelength …
Some Ecological Effects Of The Oil Industry On Farmland In East Central Illinois, Dale E. Fruendt
Some Ecological Effects Of The Oil Industry On Farmland In East Central Illinois, Dale E. Fruendt
Masters Theses
Between June, 1970 and July, 1971 a two square mile area in East Central Illinois served as a study area for the effects of the oil industry on farm land. Observations were made on several farms concerning the activity of oil companies and interviews with farmers were held. Two areas of farmland were given special attention. One was a clover field where salt water had flooded a portion of the field. The other area was a corn field where oil had flooded approximately eight acres of land. Random samples of invertebrates were taken in both of these areas as well …
