Alumna’s Research Leads to International Protection of Endangered Shark Species F or Lucy Howey-Jordan, a 2004 biology graduate, every week is shark week. She credits Virginia Tech with fostering her passion for wildlife conservation and introducing the foundation for a career in shark research. After graduating from Virginia Tech, Howey-Jordan attended Nova Southeastern University in South Florida and received a master’s in marine biology. She is the now the scientific liaison for Microwave Telemetry Inc., where she helps scientists worldwide with development of research projects. She also conducts her own scientific studies. Her primary focus has been to aid in the international protection of the oceanic whitetip shark, which is listed as critically endangered in the Northwest Atlantic and vulnerable globally by the International Union for the Conservation of Nature’s Red List, a comprehensive list of the global conservation status of biological species. Referred to as “the most dangerous of all sharks” by 20th century French conservationist Jacques Cousteau, oceanic whitetips remained untouched in the Atlantic as a subject of research until Howey-Jordan and her team performed their remarkable and novel study. In 2010, with a group of international scientists, Howey-Jordan launched a pilot study in the Bahamas using satellite-linked archival transmitters to track the movements of the shark, which has suffered an estimated 90 percent decrease in population. The study was published in the science journal PLoS ONE in February 2013 with Howey-Jordan as the lead author. (www.plosone.org/article/ info%3Adoi%2F10.1371%2Fjournal.pone.0056588) She and her team began their study of oceanic whitetips knowing the shark population was in decline and that the species was poorly studied in relation to other large open-ocean sharks. Partially because of the novelty of the research, its publication received widespread positive press coverage through traditional, mainstream newspaper and online news sites. As part of a larger effort to increase awareness of the shark’s decline and have it listed as an endangered species, Howey-Jordan and her colleagues purposely timed the publication date of their manuscript to correspond with the 16th meeting of the Convention of International Trade in Endangered Species of Wild Flora and Fauna held in www.science.vt.edu by Katherine Fairbanks March 2013 in Bangkok, Thailand. The United States co-sponsored a proposal with Brazil and Columbia to grant protection for oceanic whitetip sharks using Howey-Jordan and her colleagues’ paper to show trans-political migrations of this species as foundation for their protection. “After nearly two weeks of deliberation and opposition from countries such as China and Japan, the oceanic whitetip shark narrowly received landmark protection under Appendix II (the enforcement of strict trade regulations) along with the porbeagle shark, three species of hammerhead shark, and two species of manta rays,” she said. The U.S. Fish and Wildlife Service considered this success as the “most significant advancement at the meeting,” especially considering the rejection of proposals for other critically endangered species, such as polar bears and the American crocodile. Howey-Jordan and her colleagues continue their study of the shark, having tagged more than 60 individuals over the past three seasons in an effort to study their movement and habitat use. Recent expansions of the study include genetic and reproduction components. (Left) Howey-Jordan and her team conduct an ultrasound on a pregnant oceanic white tip. (Above) Howey-Jordan tags a shark. Currently, the group (composed of scientists at Stony Brook University and Cape Eleuthera Institute) also collaborates with researchers from the University of North Florida to analyze blood collected from female oceanic whitetips for hormonal markers present during pregnancy. Over the past two field seasons, the team conducted ultrasounds on many of the female sharks captured and confirmed pregnancy in several. Tracking data from the confirmed gravid females could provide important insights into the protection, life history patterns, and sexually segregated migrations of the species. 9
