Aquatic Plant Community Changes in Freshwater Ponds Recently Invaded by Elodea canadensis on the Western Copper River Delta, Alaska

Creator:: Elizabeth, Camarata A.
Abstract:: Establishment of a non-native plant species in new habitats beyond their native range is associated with inherent changes in ecosystem properties. These changes may be dramatic or subdued, and consequences may be positive or negative depending on characteristics and response of the resident ecosystem. Non-native aquatic plant species in the...

An Interdisciplinary approach towards understanding late Pleistocene ice sheet change

Creator:: Cuzzone, Joshua K.
Abstract:: The results presented in this dissertation address a number of questions regarding late Pleistocene and Holocene ice-sheet and climate interactions, spanning disciplines involving paleoclimatology and atmospheric science. These studies use various techniques in geochemistry, climate modeling, and ice-sheet modeling to address ice- sheet response to climate and the attendant interactions...

Application of Cosmogenic Nuclides and Argon Geochronology to Paleoclimate, Paleomagnetism, and Paleohydrology

Creator:: Balbas, Andrea M.
Abstract:: This dissertation uses argon geochronology and cosmogenic nuclide surface exposure dating methods to address three research questions. The first question concerns a geomagnetic instability recorded in lava flows on the island of Floreana in the Galapagos Archipelago. Changes in the Earth’s magnetic field (intensity and orientation) occur frequently throughout geologic...

Trained peer counselor effect on the personal growth of freshman students at a private, Liberal Arts college

Creator:: Willis, JoAnn
Abstract:: The primary problem of this study was to investigate the effectiveness of trained peer counselors on the personal growth of freshman students at a small liberal arts college. An effort was also made to determine if training residence hall student assistants in counseling skills affected freshman perceptions of those assistants.A...

Biology of the two external Acarapis species of honey bees : Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler (Acari: Tarsonemidae)

Creator:: Ibay, Lilia Armendez
Abstract:: The biology of the two external Acarapis mites of honey bees, Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler was studied. It was observed that both Acarapis species have similar developmental period (8-9 days) with males emerging earlier than females. Mite load and infestation rate of A. dorsalis decreased as bees...

Play behavior in the golden hamster

Creator:: Kreitlow, Jean Louise
Abstract:: Intensive observations were made of play behavior in the young hamster (Mesocricetus auratus) from 14 to 54 days of age. Behavior was recorded using movie film and a multi-channel event recorder. Play was first seen at 14 days of age. The amount of play increased rapidly thereafter, remaining relatively high...

Ecotypic variation of Schoenoplectus pungens (Vahl) Palla in response to salinity and inundation

Creator:: Del Giudice Tuttle, Elena
Abstract:: Local adaptation in plants may hold the key to understanding the level of resilience of an ecosystem and probability of persistence of a species in the face of rapid anthropogenic changes in climate and disturbance regime. Clonal species are especially important in wetlands, one of our most productive and vulnerable...

Structural and functional dissection of the vaccinia virus thymidine kinase enzyme

Creator:: Black, Margaret E.
Abstract:: Thymidine kinase is a key enzyme in the nucleotide salvage pathway, catalyzing the production of dTMP from thymidine and ATP. In order to identify the structural features of the TK protein and/or primary amino acid sequences which contribute to the catalytic and regulatory activities of this enzyme, an in vitro...

Ecophenology and Control of European Frogbit in a Hybrid Cattail Marsh of the St. Marys River, Michigan

Creator:: Wellons, Kathryn C.
Abstract:: Great Lakes coastal wetland communities are threatened by the impacts of invasive plants on ecosystem function and biodiversity. What allows invasive plants to become dominant in invaded communities can be hard to define and context-dependent. Traits associated with invasion success in wetland systems – rapid vegetative growth, competitive superiority in...
