Light Pollution Levels On Beaches: How Window Tinting Effects Disorientation Of Sea Turtles On Hilton Head Island, Kathryn (Kate) Hettiger
Biology: Student Scholarship & Creative Works
Loggerhead sea turtles, an endangered species, are decreasing at alarming rates worldwide. Artificial light from beachfront hotels on Hilton Head Island are causing disorientation in Loggerhead sea turtle hatchlings affecting their ability to successfully find the ocean. To mitigate this, exterior windows facing the ocean will be tinted using either tinting spray, which will be implemented at the Marriott Grande Ocean, or using tinting film, which will be implemented at the Marriott Westin. During the typical nesting and hatching season (May-October), sea turtle hatchling tracks will be recorded using drones to compare the effects of various levels of light pollution …
Reconstructing Isotelus Rex, Brian White
Reconstructing Isotelus Rex, Brian White
Fall Showcase for Research and Creative Inquiry
Isotelus rex is the largest trilobite currently known at over 720 mm in length, and by extension is one of the largest arthropods known. However, despite these accolades, it is relatively unknown in both the public consciousness and in the scientific community. This is partially due to its scant visual database, with barely any artistic restorations to help represent its life appearance. In order to rectify this, a digital reconstruction of Isotelus rex is produced utilizing programs such as Blender and Zbrush. The final result of the work is a fully animated restoration of the trilobite, bolstering its visual database …

Scanning Electron Microscopic Analysis Of Developmental Speed's Effect On Symmetry In Drosophila Melanogaster, Kyle Hiatt
Fall Showcase for Research and Creative Inquiry
The purpose of this project is primarily to examine the effects of development speed on symmetry in Drosophila melanogaster when employing methylparaben, an anti-microbial preservative, as an additive to the organisms' growth medium. This paraben was selected due to its studied effects on prolonging the length of juvenile development. The research question being examined in this project is whether manipulating developmental speed by lengthening the average developmental cycle would lead to more overall symmetry as opposed to a shorter developmental cycle speed. Baseline assays of juvenile developmental speed of Drosophila melanogaster, both groups with and without methylparaben growth medium, will …
Why Is It Beneficial For Crustaceans To Become Crab-Like?, Dylan Blanton
Why Is It Beneficial For Crustaceans To Become Crab-Like?, Dylan Blanton
Fall Showcase for Research and Creative Inquiry
There are two types of crabs, true crabs and false crabs. The true crabs, Brachyurans, evolved from the original lineage and false crabs, Anomurans, have evolved from separate lineages. The main research plan is to analyze the use of each morphological feature that is similar between the Brachyurans and Anomurans and identify if it provides an edge over other competitive organisms that do not exhibit that trait. This is planned to be studied by identifying and observing if certain crab-like morphological traits provide any advantage over organisms without those traits. This will be executed by finding several locations associated with …

The Effect Of Distance From Habitat Fragmentation On Biodiversity Of Invertebrates, Diego Sifuentes, Coleman Taylor
Fall Showcase for Research and Creative Inquiry
Habitat fragmentation happens when human interaction causes an organism's environment to emerge in discontinuities in their habitat. This leads to degradation and disrupts the ecosystem as a whole. This experiment will try to answer the question if habitat fragmentation is still prevalent on invertebrates at a further range. This will be achieved by setting two sites with pitfall traps on both sides on the fragmentation and then a third site will be added at the same distance from the first two sites. It is hypothesized that there will be a less abundance of invertebrates on sites A and B while …
