Coral Species Distribution And Percent Cover Of Sessile Organisms On Protected And Non-Protected Coral Reefs In Digir, Buga, Dubbir, And Kanir Kinnidup, Guna Yala, Panama, Sarah Paulson

Independent Study Project (ISP) Collection

Coral reefs are the most productive, biodiverse ecosystems in the ocean despite covering only <.5% of the ocean floor. In today’s changing climate, coral reefs face a multitude of threats including ocean warming, coral bleaching, ocean acidification, overfishing, increasing human population, and coral mining, among others. One way to protect coral reefs is to establish a marine protected area to limit damage and contamination. This study aimed to examine coral species distribution as well as percent cover of sessile organisms and substrates including coral, fire coral, algae, and sponges on protected and non-protected reefs in order to attempt to analyze the effect of protection on coral reefs in Guna Yala, Panama. Based on the data collected, protected areas had higher algae cover (P<.01, df=107), lower coral cover (P<.0001, df=138), and a higher relative abundance of corals with a “weedy” life history such as Porites astreoides (P<.05, df=80). The data also showed that uninhabited islands tended to have significantly higher average coral cover (P<.0001, df=146) and lower average algae cover (P<.0001, df=161), as well as lower relative abundance of P. astreoides (P<.01, df=134). When the protected site sampled was compared to an unprotected site that was around the same island, the protected area was found to have higher coral cover (P<.01, df=71) and lower algae cover (P<.05, df=72) than the unprotected area. Ultimately, lack of human population and protected status were found to be positive factors for coral reef health, and future study should be done to further examine the relationship between these two factors.

The Methane-Oxidizing Capability Of Pumice Biocovers On Icelandic Landfills, Mitchell P. Miller

Independent Study Project (ISP) Collection

Pumice has been shown in laboratory biofilter experiments to improve the oxidation of methane (Pratt et al. 2012, Pratt, Tate, & Deslippe 2012). Pumice biocovers were tested on two Icelandic landfills, Kirkjuferjuhjáleiga and Álfsnes. Seven biocover plots were dug and filled with a 50:50 blend of pumice and native soil. CH4 and CO2 were measured using the static chamber method before and after biocover placement. After one week, the CH4:CO2 ratio was reduced on four of the seven plots, weakly indicating that pumice biocovers may be an effective way to better oxidize landfill methane.
