Importance Of Ubiquitin-Mediated Degradation On Diacetyl Chemosensation In C. Elegans, Ellen Zocher, Nelson Ruth
Scholars Week
Ubiquitin is a small regulatory protein that can be attached to other proteins in a cell, tagging them for destruction. Ubiquitin plays a critical role in regulating the abundance and activity of many proteins. We examined the role of ubiquitin and the cellular pathway it follows in olfactory neurons in the model organism C. elegans. C. elegans senses and moves towards sources of diacetyl, a volatile compound generated by the bacteria it consumes. This behavior is dependent on the diacetyl receptor, ODR-10. We hypothesized that the ubiquitin-mediated degradation system is involved in the regulation of this sensory receptor. Using transgenic …

Can Collection Specimen Data Reveal Temporal Shifts Due To Climate Change?, Julie Maurer
Scholars Week
Climate change is altering the distribution, behavior, and migration patterns of many species. Typically, these responses are documented studies in which standardized methods are used to collect population or behavioral data over several years. Multi-decade studies are rare and few predate the recent dramatic increase in global temperatures, limiting our ability to understand long-term consequences of climate change. Natural history (NH) collections offer a potential solution; they hold a wealth of species occurrence documentation spanning from decades to centuries. However, because the sampling of natural history collectors is spatially and temporally haphazard, it remains unclear whether NH data is useful …

Organic Content And Silt To Sand Ratio In Correlation With Porewater Sulfide Concentrations Found In Eel Grass (Zostera Marina) Beds, Clarissa Felling
Scholars Week
Eel grass, Zostera marina, beds are a vital habitat for both economically valuable species and nutrient cycling. Populations of Z. marina in Washington State have either stayed consistent or dwindled slightly. To increase the distribution of eel grass in Washington State knowing the organic content and silt to sand ratio is important for these plants survival. If this data correlates to sulfide concentrations, which can inhibit the abundance of eelgrass, department officials can locate viable places for new beds. Sediment samples were taken from four different eelgrass sites around Skagit County. Each sample was divided in two; one heated at …
