Abstract: <p>The amitochondrial protozoan, Giardia intestinalis, encodes four members of the cytochrome b5 (CYTB5) family of heme proteins of unknown function. While homology models can predict the likely fold of these proteins, supporting experimental evidence is lacking. The small size of the cytochromes (~16 kDa) makes them attractive targets for structural analysis by Electron Paramagnetic… more Full Text: NMR and EPR Studies on Cytochrome b5 Isotypes of Giardia intestinalis A thesis submitted to the Committee on Graduate Studies in Partial Fulfillment of the requirements for the degree of Master of Science in the Faculty of Arts and Science Trent …

Abstract: <p>Chemical cues are used commonly by prey to identify predation risk in aquatic environments. Previous work has indicated that negatively-charged ions of m/z 501 are possibly a kairomone that induces anti-predator responses in tadpoles. This thesis found that this ion species: (i) is produced by injured tadpoles; (ii) exhibits increased spectral intensity with higher tadpole biomass; and (… more Full Text: THE ORIGIN AND ECOLOGICAL FUNCTION OF AN ION INDUCING ANTIPREDATOR BEHAVIOUR IN LITHOBATES TADPOLES A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of …
