Undergraduate Research Symposium

Harmful Algal Blooms are a collection of algae in a body of water that can cause serious environmental issues and health problems in both people and aquatic organisms. Dinoflagellates are microscopic, unicellular, and eukaryotic organisms that are well known for forming harmful algal blooms because of eutrophication. Coastal Virginia suffers from HABs in the Chesapeake Bay and its tributaries. A common species of dinoflagellate, known as Margalefidinium polykrikoides exists in the Chesapeake Bay. The purpose of this study is to determine if sediment resuspension produced by wind generated surface gravity waves cause cysts (dinoflagellate resting stages) to be suspended into …

Link Between Local Phenology And Climate Change, Blake Steiner, Tatyana Lobova

Virginias Collegiate Honors Council Conference

The SouthEast Virginia Phenology Project was initiated as collaboration between Norfolk Botanical Garden and Old Dominion University in 2010 to document phenology of seven native plants and potential effects of the climate change on their life cycle. The air temperature in Norfolk has increased on average by 0.02ºC per year since 1980. Four out of seven of taxonomically diverse plant species (Mayapple, Flowering Dogwood, Highbush Blueberry, and Common ButtonBush) exhibited significant sensitivity to warming temperatures. Of these four, only Common Buttonbush (Cephalanthus occidentalis) had shown significant phenophases shift. Specifically, first flowering and first fruiting dates had shifted 2.7 …
