Systematics Of Protosteloid Amoebae, Lora Lindley Shadwick

Graduate Theses and Dissertations

Because of their simple fruiting bodies consisting of one to a few spores atop a finely tapering stalk, protosteloid amoebae, previously called protostelids, were thought of as primitive members of the Eumycetozoa sensu Olive 1975. The studies presented here have precipitated a change in the way protosteloid amoebae are perceived in two ways: (1) by expanding their known habitat range and (2) by forcing us to think of them as amoebae that occasionally form fruiting bodies rather than as primitive fungus-like organisms. Prior to this work protosteloid amoebae were thought of as terrestrial organisms. Collection of substrates from aquatic habitats …

The thesis investigates the following problems: (1) whether or not there is any correlation between temperature change and respiratory quotient, (2) whether or not respiratory inhibition by cyanides is influenced by temperature, and (3) whether or not the cytochrome-cytochrome oxidase type of respiratory system is concerned chiefly with carbohydrate metabolism in Pelomyxa carolinensis.
