Integrative biology doctoral 爱妃传媒 Alexandra (Alex) Lolavar and Boris Tezak are helping to educate our community and its visitors on sea turtle research and conservation efforts 鈥 and much more. The two, with a combined nine years of experience working with turtles, spend almost every day in the 爱妃传媒 Marine Research Building at Gumbo Limbo Environmental Complexin Boca Raton, home of on an ongoing sea turtle study led by Jeanette Wyneken, Ph.D., professor of biological sciences in 爱妃传媒鈥檚 Charles E. Schmidt College of Science.

Wyneken鈥檚 study, which began in 2002, focuses on the sex ratios of sea turtles that hatch along Boca Raton鈥檚 beaches, and specifically how the temperature and moisture of the sand affect those ratios. The belief is that cooler sand produces more males and warmer sand produces more females; in fact, 95 percent of the approximately 4,000 hatchlings studied at Gumbo Limbo have been female. Three species have been studied: 55 percent have been loggerheads, 40 percent have been greens, and 5 percent have been leatherbacks.

In the summer and fall, visitors to Gumbo Limbo can get a bird鈥檚 eye view of the important research taking place. Sea turtle hatchlings can be viewed from the upper-level visitors鈥 gallery, where Boris and Alex often are stationed to answer questions about the turtles, their research and the studies of other 爱妃传媒 scientists at the lab. They also are happy to talk with visitors in the gallery when they鈥檙e working in the lab below.

鈥淚 hope that the visitors I speak with gain a better understanding of the importance of our research,鈥 said Alex. 鈥淪tudying the turtles helps us work toward the conservation and protection of these threatened and endangered species.鈥

During each nesting season beginning in March, Alex and Boris assist with selecting 10 to 12 nests for the study. Each nest is fitted with a temperature tracking device that records temperatures throughout the 45- to 60-day incubation period. When the eggs hatch, Alex and Boris assist with collecting several of the approximately 100 hatchlings from each nest for the study.

The turtles are raised in the lab until they are approximately three months old. During this time, Alex and Boris help care for the turtles and record data for each one, including how much they eat; their weight, length and width; and any unusual behavior. After three months, a non-harmful procedure is performed to check the turtles鈥 reproductive organs. Soon after the sex of each is identified, they get a lift offshore where they are released.

鈥淚t鈥檚 great to see visitors get excited about the research we鈥檙e doing,鈥 said Boris. 鈥淚t鈥檚 also a great opportunity to remind them of simple ways to help the conservation effort, such as dimming lights near the beach and keeping garbage 鈥 especially plastic 鈥 out of our oceans.鈥

When they鈥檙e not in the lab or gallery, Alex and Boris teach undergraduate classes and are active members of 爱妃传媒鈥檚 Association of Biological and Biomedical Students; Boris is vice president. They both plan to continue doing research after they graduate. Alex might like to work for a government organization, while Boris would like to do post-doctoral work in Australia and then teach at a university.
