Light Pollution Levels On Beaches: How Window Tinting Effects Disorientation Of Sea Turtles On Hilton Head Island, Kathryn (Kate) Hettiger Dec 2021

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 …

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …

Urban stream syndrome is described as the deterioration of stream health in an urbanized watershed and is associated with the loss of ecosystem services, which in turn degrades downstream environments. One key symptom of the urban stream syndrome is reduced processing of inorganic nitrogen. Previous research suggests that as urbanization increases and water quality decreases, the uptake length (Sw) of inorganic N increases. This indicates that the stream is increasing the export of N downstream compared to in situ incorporation of N into the ecosystem. We measured uptake length (Sw) of NO3, using a pulse addition method, along 9 different …
