How Weather Affects Sea Turtle Nests

Jeanette Wyneken, Ph.D.
Professor of Biological Sciences and Director, FAU Marine Lab at Gumbo Limbo Environmental Complex

What can be done to help lower the nest temperatures? Anything that we can do to help? By we, I mean Gumbo Limbo and scientists as well as volunteers and people.
Time code 0:00

During excessively hot years, with minimal rain, would it make sense to erect a "tent cover" to cool the nest somewhat, and make it easier on the boys?
Time code 1:22
Is there a significant difference in the temperature: female ratio in DC (leatherback) and CM (green turtle) nests compared to the shallower CC (loggerhead) nests, or are you just doing your study on CC (loggerhead) nests?
Time code 0:00

What is it about turtles that compels you to study them?
Time code 1:00

Do you do any intervention by removing eggs and putting them in a controlled environment?
Time code 2:09

How many nests on average are being studied each season? What percentage of total nests are being studied?
Time code 2:40

How long do sea turtles live?
Time code 3:39

We found your stakes after the last hurricane. Where do we return them the next time this happens?
Time code 4:49

Is it true that all sea turtles return to where they were born to nest?
Time code 5:15

Would you be allowed to remove the eggs from the nests if there is a large storm?
Time code 6:11

How does the increased amount of females born impact opportunities for finding male mates? Can males mate with multiple females?
Time code 7:09

How old do you have to be to volunteer at the FAU Marine Lab?
Time code 8:14

You briefly mentioned the defects in the hatchlings. Can you describe these defects?
Time code 9:00
Is the temperature causing the unhatched sea turtles to change sex or is it because males have lower survival rates in high temps?
Time code 0:00

Do you manipulate the temperatures of the turtles on the lab areas?
Time code 1:24

Do we know if rainfall would be better during the beginning on ending of the nesting time?
Time code 2:22

How do you determine the sex of a hatchling?
Time code 4:02

What ratio of adult male/female can maintain the population?
Time code 5:15
Have there been observations of shifting nesting times associated with a changing climate?
Time code 0:00

Do you track the baby turtles in the ocean? If so, how?
Time code 1:23

How long can they reproduce?
Time code 3:03

Are scientists considering nests being carefully moved and then temperature manipulated to create all male hatchlings to ensure a stronger male population?
Time code 4:49

If you were a turtle what turtle would you be?
Time code 7:00

Does acid rain effect the eggs differently?
Time code 7:59
Do turtles have scales on them?
Time code 0:02

Other than loggerheads, which sea turtles were your favorite to work with?
Time code 0:35

How old were you when you really wanted to become a biologist?
Time code 1:59

How can you tell which species the turtle is when you are looking at a turtle nest?
Time code 3:16

As a management tool, has consideration been given to moving nests farther north so they would ultimately return to those northern areas to nest themselves?
Time code 4:10

What do you do if you catch poachers in the act?
Time code 6:35

How will everyone staying home affect sea turtle nesting rates?
Time code 7:11

What do they eat and is their food sources impacted by current warmer environmental conditions?
Time code 8:13

If you were a turtle what turtle would you be?
Time code 10:12
Is there a relationship between nest temperature and sex?
Time code 0:21

There are some early nests of leatherbacks in February on Hutchinson Island and some other places this year, how many males would you expect to come out these nests?
Time code 0:44

How many sample nests does the sex ratio graph represent?
Time code 1:44

In a perfect world, what is their lifespan?
Time code 3:17

How are you mitigating adverse environmental impacts?
Time code 4:07

What is a drown nest?
Time code 5:12

What’s your favorite turtle?
Time code 6:20

Are sea turtles “tied” to the areas they hatched? Do they only return to nest to the beaches they hatched on, or might they nest further north as the weather warms?
Time code 6:54
Although it is already looking like a hot summer, do you think that the fact that less people are on the beach will give them a fighting chance?
Time code 0:05

How many nests do you have on record for this year?
Time code 1:44

Do you move a nest once you observe it is above the thermal maximum to try and save the embryos? Or is that a more risky option?
Time code 2:22

Are fellow scientists around the world seeing the same results? Perhaps there are microclimates that are not exhibiting the same conditions?
Time code 3:35

Do loggerheads nest in the Bahamas? Where do the other proportion of loggerheads in the Atlantic nest?
Time code 5:10

What can we as lay people do to help preserve all species' habitat?
Time code 6:11

Is it true that the closed beaches have changed the turtles’ behavior?
Time code 8:16

Do they have to sun bath?
Time code 9:39
