Ultrastructure Of Diplonema Ambulator Larsen & Patterson (Euglenozoa) And Its Relationship To Isonema, Donald Ott Oct 2014

Ultrastructure Of Diplonema Ambulator Larsen & Patterson (Euglenozoa) And Its Relationship To Isonema, Donald Ott

Donald W. Ott

The fine structure of a small phagotrophic protist, Diplonema ambulator, associated with deteriorating leaves of some species of the common fresh-water aquarium plant, Cryptocoryne is described. The organisms bear two short flagella which arise subapically and have a flexible cell surface often exhibiting pronounced changes in shape. Under the plasma membrane is a single layer of interconnected microtubules. Adjacent to the microtubules is a peripheral reticulate mitochondrion with plate-like cristae and numerous dense beaded inclusions. A large complex microtubular-based feeding apparatus extending to the cell surface is surrounded by several food vacuoles. Because the organism fits the light microscopic description …

Development Of The Carposporophyte Of Kallymenia Reniformis, Donald Ott, Max Hommersand Oct 2014

Development Of The Carposporophyte Of Kallymenia Reniformis, Donald Ott, Max Hommersand

Donald W. Ott

The development of the carposporophyte in Kallymenia reniformis involves an elaborate series of interactions between reproductive and vegetative tissues. Following fertilization, the inner cells of the carpogonial branches form processes that unite with the supporting cell and with each other, giving rise to a large fusion cell. A number of medullary filaments are enveloped and incorporated within the developing fusion cell. Secondary filaments may be produced from medullary cells outside the fusion cell after connecting filaments have been initiated. Connecting filaments are nonseptale and wind their way through the medulla. The presence of a connecting filament in the vicinity of …

New Records Of Vaucheria Species (Xanthophyceae) With Associated Proales Werneckii (Rotifera) From North America, Donald Ott, Robert Wallace, Morgan Vis, Robert Verb Oct 2014

New Records Of Vaucheria Species (Xanthophyceae) With Associated Proales Werneckii (Rotifera) From North America, Donald Ott, Robert Wallace, Morgan Vis, Robert Verb

Donald W. Ott

The presence of galls on species of Vaucheria was investigated both seasonally and in a number of locations in North America. These galls are induced by the rotifer, Proales werneckii. In an Ohio stream, Vaucheria bursata and V. geminata were found to have galls throughout their growing season; September to January. Galls were most abundant in October and ranged in size from 90–260 μm in width and 140–790 μm in length. New records of Vaucheria with galls from locations in Alabama, California, Georgia, Louisiana, North Carolina, Ohio and Tennessee are reported. Three of the five taxa collected were not previously …

Vaucheriae Of North Carolina, Donald Ott Oct 2014

Vaucheriae Of North Carolina, Donald Ott

Donald W. Ott

Marine Vaucheriae of North Carolina were investigated in the field and in culture for 4 years. Of the 11 species collected, 4 are new records for North Carolina and 2 are previously unreported species. A new section is established, Acrandrae, to contain Vaucheria acrandra sp. nov. and Vaucheria adela sp. nov. The diagnostic character of the new section is the production of androphores directly from the terminal portion of the main filament rather than from a special cell produced laterally on the filament as in the section Androphorae.
