Electronic Theses and Dissertations
Chemosensory behaviors are used by many mammalian species to assess chemical signals in the environment. These chemical signals may contain important information about reproductive state, identity, status, or location of conspecifics. Elephants are a long-lived species and males reproduce at a much later age than females, which provides a protracted developmental period for males. This study examined chemosensory behaviors in a population of African elephants living in Addo Elephant National Park, South Africa and demonstrated that patterns emerge as elephants develop and approach sexual maturity. Older pubescent males (15-19 year olds) performed more chemosensory behaviors than younger pubescent males (10-14 …

Proteins bind to DNA to form switches and circuits that control the flow of genetic information from DNA sequence to the physical components of cells and organisms. The dynamic performance of genetic switches depends on the coupling of the comprocesses of transcription and translation to protein-specific folding, assembly and binding reactions. For many model circuits protein dimerization and DNA binding are fast relative to the time scale of transcription and translation and thus amenable to modeling by statistical thermodynamics. In these cases, the distribution of proteins between monomers and dimers and between nonspecific and specific DNA complexes can be simply …
