A Biosystematic Study Of Three Plant Pathogenic Fungi, Richard James Langham
A Biosystematic Study Of Three Plant Pathogenic Fungi, Richard James Langham
Masters Theses
Isolates of Chalara australis, Eucalypt Ceratocystis, and Ceratocystis virescens were grown on Potato Dextrose Agar, Malt Extract Agar, and Czapek Agar and examined as part of a biosystematic study on these fungi. Basic micromorphological and macromorphological data on the cultures were recorded and the taxa were found to be morphologically similar. Tissue isolates and single spore isolates were crossed within these taxa and an interspecific cross performed. Chalara australis was found to be either asexual or have only one mating type present in the cultures studied. Eucalypt Ceratocystis was found to have a mating system characteristic of bipolar …
Relative Sensitivities Of Diatoms To Selected Heavy Metals, Jennifer E. Carlson
Relative Sensitivities Of Diatoms To Selected Heavy Metals, Jennifer E. Carlson
Masters Theses
Baseline data, including diatom community structure, metal concentrations of water, sediments and periphyton of the Embarras River were determined previously (Vaultonburg, 1991). Data on diatom community structure in conjunction with efforts to identify relative sensitivity of diatoms may be useful in establishing an effective method for biomonitoring metal pollution in the Embarras River and other aquatic systems. The main objectives of this project were: i) develop a bioassay method; ii) evaluate relative toxicities of several metals towards diatoms; and, iii) evaluate relative sensitivities of diatoms toward dissolved metals.
Unialgal cultures of Cyclotella meneghiniana, Navicula vaucheriae, and Nitzschia palea were isolated …
