EARTHtalk! lecture to highlight changes in reefs, threats to modern reef ecosystems]]> A University of Arkansas at Little Rock assistant professor will lecture Sept. 18 on changes in ocean reefs through time, the implications of human impacts on modern reef systems, and actions being taken across the world to protect reefs from terminal decline.聽 Dr. Ren茅 Shroat-Lewis, U.S. Navy veteran and assistant professor of Earth sciences, will give the talk, 鈥淒iving Deeper: Exploring the Changes in Reefs Through Time鈥� at 6 p.m., Wednesday, Sept. 18, at the College of Engineering and Information Technology building auditorium. The talk is part of the Department of Earth Sciences EARTHtalk! series. 鈥淚n the last 540 million years, reefs have diversified, undergone extinctions, and diversified again,鈥� said Shroat-Lewis. 鈥淐hanges in climate have played a role in this process, with rising greenhouse gases and ocean acidification causing the decline of organisms and the reefs they built.鈥� According to Shroat-Lewis, pollution, sedimentation, physical damage, tourism, and global warming are the principle threats to modern reef ecosystems.聽 鈥淓vidence suggests that coral reefs will pass a point of no return around 2040 and go into terminal decline, eventually disappearing at the end of this century. Based upon evidence from the fossil record, it may be millions of years before they return,鈥� Shroat-Lewis said.聽 Shroat-Lewis currently researches coral reef diversity on San Salvador Island, the Bahamas. She contributes paleoecology presentations at geology conferences and publishes research findings in the PALAIOS journal.聽]]> /news-archive/2018/03/27/signature-experience-award-takes-student-bahamas/ Tue, 27 Mar 2018 13:00:53 +0000 /news/?p=69862 ... Signature Experience Award takes student to the Bahamas]]> Rebecca Bishop, a Donaghey Scholar whose research interests lie in the health of diseased coral reef, will use her Signature Experience Award funds this summer to travel to San Salvador, an island in the Bahamas, to collect and analyze coral reef samples at the Gerace Research Centre. Bishop, a sophomore environmental geology major, was among the first group of University of Arkansas at Little Rock students to receive Chancellor Andrew Rogerson鈥檚 newly instituted Signature Experience Award. During the fall 2017 semester, he awarded 79 糖心Vlog传媒 Little Rock students $1,000 to assist in the purchase of materials for a one-semester project or experience in research or creative works. 鈥淚’ve always been interested in coral reefs because of how incredibly diverse and important they are as an ecosystem,鈥� Bishop explained. 鈥淭he more I learned about corals, however, the more I understood how much danger they were in.鈥� Through her research, Bishop found that the frequency of increasingly warming temperatures and extreme weather events threatened the future of coral reefs. To gain a better understanding of how these conditions impacted the animals, Bishop decided to explore them in San Salvador, an island with very little literature about the ecological health of its reefs. 鈥淭here is still a lot we don’t know about coral diseases and their causes, but when I learned that I could help contribute to the information surrounding coral and their health, I became eager to start my own research,鈥� she said. Bishop has already dived into the discovery stage of her project, 鈥淚ncidence of Coral Reef Disease on San Salvador Island.鈥� From March 19-24 during spring break, she and her Geology and Ecology of the Bahamas class traveled to the Bahamas for field study. While there, Bishop began the preliminary work of her project, scoping out sample sites and inspecting coral diseases. Bishop鈥檚 overall research goal seeks to continue the monitoring of coral reefs, while using the findings to help establish a marine reserve with active management and a regulations enforcement plan for San Salvador鈥檚 reef system. Dr. Ren茅 Shroat-Lewis, assistant professor of paleontology and geoscience in the Department of Earth Sciences, serves as her advisor. Bishop will complete her bachelor鈥檚 degree in geology in 2020, and afterward, plans to head to graduate school to study oceanography. Not only is Bishop thrilled to do the research she enjoys, she鈥檚 also grateful to have the university鈥檚 support, expressed through the Signature Experience Award, to back her in her endeavors. 鈥淭he Signature Experience Award has been extremely important for me,鈥� Bishop said. 鈥淏ecause my research focuses on an area outside of the United States, the costs associated with my project are a bit high. If it weren’t for the help and support I’ve received from the Signature Experience Award, I wouldn’t be able to conduct such exciting and unique research.鈥�  ]]>
