Evolution Of Voltage-Gated Ion Channels, Kevin Gregory Bennett, Kevin Bennett
Evolution Of Voltage-Gated Ion Channels, Kevin Gregory Bennett, Kevin Bennett
Master of Science in Integrative Biology Theses
Voltage-gated Ion Channels (VICs) form a superfamily of energy-independent membrane transporters that facilitate the transfer of charged sodium, calcium, and potassium ions across the cell membrane (Hodgkin & Huxley 1952). The channels contain a selective ion-conducting pore along with several other structural and gating features that come together to form a functional hetero- or homotetramer. A comprehensive phylogenetic study of all available proteins aimed at finding unknown distribution and illuminating evolutionary paths would be immensely useful in understanding relationships of structure, function, and organismal distribution. This phylogenetic analysis of VICs will be immensely useful in characterizing functional and structural distribution, …
Evaluating In Situ Grazing Patterns Of Lytechinus Variegatus And Their Effects On Seagrass Beds Of Thalassia Testudinum, Adrianna Parson
Evaluating In Situ Grazing Patterns Of Lytechinus Variegatus And Their Effects On Seagrass Beds Of Thalassia Testudinum, Adrianna Parson
Master of Science in Integrative Biology Theses
The sea urchin Lytechinus variegatus is a known grazer of the seagrass Thalassia testudinum, and has been known to denude vast stands of seagrass beds at high densities. Outside of these denudation events, the effects of sea urchins on seagrass are poorly understood. This study examines the effects of L. variegatus on T. testudinum in situ, to understand how sea urchins are affecting seagrasses in situ. Results indicate that urchins were found in the offshore portion of the seagrass bed at densities up to 4 urchins/m2. Changes in temperature and sediment size in the bay indicate …
Changes In Frontoparietotemporal Connectivity Following Do-As-I-Do Imitation Training In Chimpanzees (Pan Troglodytes), Sarah M. Pope, Jared P. Taglialatela, Sara A. Skiba, William D. Hopkins
Changes In Frontoparietotemporal Connectivity Following Do-As-I-Do Imitation Training In Chimpanzees (Pan Troglodytes), Sarah M. Pope, Jared P. Taglialatela, Sara A. Skiba, William D. Hopkins

Human imitation is supported by an underlying ‘mirror system’ principally composed of inferior frontal (IF), inferior parietal (IP), and superior temporal (ST) cortical regions. Across primate species, differences in fronto-parieto-temporal connectivity have been hypothesized to explain phylogenetic variation in imitative abilities. However, if and to what extent these regions are involved in imitation in non-human primates is unknown. We hypothesized that ‘Do As I Do’ (DAID) imitation training would enhance white matter integrity within and between fronto-parieto temporal regions. To this end, four captive chimpanzees (Pan troglodytes) were trained to reproduce 23 demonstrated actions, while four age/sex-matched controls were trained …
