The Research and Scholarship Symposium (2013-2019)
Although agricultural needs are pressing and crop sales are vital for the local economies in southern Ohio, the resulting clearing of land has removed much of the state’s forests and natural prairies. A variety of species depend upon these habitats that have been reduced resulting in a potentially narrower ecological niche. In this study, we seek to determine the species richness and diversity of small mammals in three habitats (old field, forest, and lawn) and to evaluate factors affecting their activity. Our experimental results supported our hypothesis that the lawn site would have lower diversity than the other two sites. …

The Research and Scholarship Symposium (2013-2019)
Since 2005 when Dr. Mary Schweitzer made the first discovery, microstructures with the appearance of “osteocytes” and “blood vessels” have been recovered from fossils of various localities, dating back as far as the Triassic. The majority of these finds have come from dense, cortical bone but recently have been discovered in cancellous bone. Since her initial discovery, Schweitzer has done a lot of work to verify that these microstructures are not biofilms, but instead are original organic tissue. This project was looking to get similar results to Schweitzer’s research and to find a simple test method for the initial discovery …
