Examining The Effect Of Interstitial Space On Eastern Oysters (Crassostrea Virginica): Applications Of Photogrammetry And Three-Dimensional Modeling, Bailie Lavan
Masters Theses, 2010-2019
Global oyster populations have decreased by as much as 99% in the past century. Oysters are known ecosystem engineers, providing benthic habitat for macrofauna, linking benthic and pelagic food webs, improving water quality, and mitigating shoreline erosion. Restoration efforts are critical in re-establishing native oyster populations. In the Chesapeake Bay, where oyster loss is primarily due to severe over harvest, artificial substrates with geometric shapes are widely used in restoration efforts. However, natural oyster reefs form emergent shapes with a high degree of aggregation and many interstitial spaces (three-dimensional volumetric spaces between oysters within a reef). The lack of interstitial …

In Vitro Propagation Of A Critically Endangered African Violets (Saintpaulia Rupicola B.L. Burtt), Thomas W. Lowry Iii
Masters Theses, 2010-2019
The in vitro propagation is a promising method for the production of plants in species that are endangered, commercially valuable, and/or otherwise difficult to propagate through traditional horticultural methods. Leaf and petiole explants of critically endangered African violets (Saintpaulia rupicola B.L. Burtt) were cultured on a chemically defined medium that was supplemented with six different concentrations of thidiazuron (TDZ). The concentrations were used for either an induction medium on which the explants remained throughout development, or an induction medium on which the explants remained for 10 days followed by a basal growth medium for the remainder of the 12 …
