A host of external environmental factors can influence whether an egg hatches a male or female turtle, and one of those factors is temperature: Warmer conditions birth more females, whereas cooler ones produce males. Are they hatching? And if so, are there enough of both sexes? The team was able to verify the technique on loggerhead turtles, a species that has a simpler biology that allows for better sex determination. Once researchers realized it was reliable, they could apply it to species that are harder to identify, like leatherbacks.

Written by Jack E. The headlines transitioned from National Geographic to mastheads like the Washington Post and others, this exposure was a wakeup call and sent chills down the spines of many marine scientists and conservationists. Here at Loggerhead Marinelife Center we welcome nearly , guests and over 50, students every year.
It is our responsibility to educate our guests and keep ourselves on the leading edge of sea turtle and ocean conservation. Obviously, both male and female sea turtles are necessary to create the next generation of their species. After reading the National Geographic article I had quite a few questions so, our team, comprised of some of the most thoughtful sea turtle and ocean conservation experts gathered to compare and contrast data, and observations.
As I sat in our conference room with Dr. Justin Perrault, Dr. Charles Manire, and our chief conservation officer, Tommy Cutt, we realized that it was absolutely imperative to share with anyone that would listen that conservation of sea turtles is evolving at a shockingly fast pace.
In we kicked off our official study of sex ratios gender of sea turtles; our center will set the baseline and then monitor how this baseline changes over time — critical science to better save sea turtles for future generations. Over the past five decades, we have made huge strides to help protect sea turtle populations and their coastal habitats.
For example, the Endangered Species Act of significantly increased sea turtle conservation. Because of it, certain populations of sea turtles that were on the brink of extinction are now rebounding significantly.
Threats to sea turtles, marine life and our oceans over the past 50 years are vastly different than they were in the s; the worst offenders? Hatchlings must safely make their way from the nest, across the beach and into the water. Then, they must swim for miles until they reach sargassum weed lines near the Gulf Stream — where marine debris tends to collect. Photographed without flash; under FWC permits. Here at the Sea Turtle Hospital at Loggerhead Marinelife Center, our scientists monitor the health of our local sea turtle population.
Interestingly enough, we are able to collect more data in one year than many research laboratories can collect in multiple decades. Our 9. Our hope is that our data, analyses and insights will tell a compelling story, quickly as some of us are unsure how much time we have to impact our changing planet. We are committed to trend spotting and collaborating with top notch scientists. We must do this, because our sea turtles and their ocean home appear to be under greater threat than ever before.
The study from Australia gives us great concern, in particular when we layer in the insights from our laboratory and sea turtle hospital. During this time, post-hatchlings live in convergence zones where sargassum a type of brown algae collects in the open ocean — the same zones where marine debris collects. Over the past three years, we have found more plastic inside the stomachs of post-hatchlings, often leading to their death. Because this life stage lives in the open ocean, it is likely that we are seeing only a small portion of turtles that are affected.
Therefore, it is probable that many more are dying from plastics. Of even bigger concern is that it is not a local problem. Our oceans are interconnected by currents, one ocean, one planet; this is a global challenge. So now what? We may not know the true impact of our changing threats for years; why? It takes a sea turtle years to reach reproductive adulthood.
We need two or three decades of more data, but do we have enough time to collect this data as our planet and oceans continue to change? This question, among others, keeps us up at night. Another factor that influences sea turtle populations is light pollution. Last year our research team documented hatchling and adult disorientations as a result of beach front lighting. Some hatchlings on Florida beaches have been known to crawl over a mile in response to non-natural light.
The disorientation events documented by LMC research staff are very low in comparison to other populations in Florida. Although we see nesting success on shore, we have little — if any — control to help sea turtles once they reach the ocean. From the data, we know the ocean needs our help more than ever before. So what now? We need more advocates. Please join us in our efforts by getting involved in the conservation conversation, our sea turtles, our ocean, and the next generation need us to act, right now.

4: Sea Turtles: Hot Chicks and Cool Dudes with Boris Tezak
Every year, nesting sea turtles return to their natal beach to lay their eggs. Females come up from the water to make their nests and deposit over eggs on average in the sand, but only 1 out of hatchlings survives to adulthood.
Fun fact, the temperature of the beach actually determines the sex of hatchlings. Since this summer has been very hot, scientists expect there to be many more hot chicks than cool dudes this season. Approximately six to eight weeks after the eggs have been deposited, the hatchlings will make their way from those nests to the ocean using the reflection of the moon on the water as a guide.
Therefore, a common threat to sea turtles is disorientation caused by other sources of light. Which is why organizations like Sea Turtle Oversight Protection or STOP are working diligently to help the baby turtles find their way safely to the ocean.
The mission is to provide monitoring at night of sea turtle nests, assist those hatchlings that are disorientated with little to no impact of the natural nesting habitat.
Disorientation occurs as hatchlings are innately born to gravitate toward the brightest light and often the brightest light are from condos, hotels and the street. The City of Fort Lauderdale has a city ordinance to help protect the threatened and endangered sea turtles by reducing artificial lighting during nesting and hatching season which is March 1- November 1. Anyone can volunteer with STOP, but a volunteer must complete training in order to become permitted, making it lawful to assist sea turtles.
If anyone sees a sick or injured turtle or finds a hatchling crawling inland in Broward County they should call STOP at to dispatch permitted staff to the location. To learn more visit SeaTurtleOP. Thank you to all the local volunteers who donate their time!
