There’s World Turtle Day (May 23) then there’s World SEA Turtle Day, which is today! Why is June 16th World Sea Turtle Day? It is the birthday of Dr. Archie Carr who is widely known as “the father of sea turtle biology.” Dr. Carr focused his entire career on sea turtle research and conservation. According to The Sea Turtle Conservancy:
Archie Carr was a great biologist. His early descriptive studies of turtles set the standard of quality in the field of natural history. Later on, as he focused on sea turtles, he moved toward ecology and behavior, although his work always retained a taxonomic and evolutionary perspective. For decades the National Science Foundation (and the Sea Turtle Conservancy and the Office of Naval Research) supported his research at Tortuguero, enabling him to mount one of the longest lasting and most intensive studies of an animal population that has ever been done. To date, more than 35,000 adult female green turtles have been tagged at the research station at Tortuguero. From this effort have come papers by Archie Carr, his students, and other investigators on orientation, migration, nesting behavior, nest physiology, sensory physiology, nutrition, demography, and other subjects. Almost all of the studies have significance for conservation — Archie Carr was a conservation biologist long before the field was recognized.
Of the seven sea turtle species, five are listed on the IUCN Red List as either vulnerable, endangered, or cirtically endangered. They are: leatherbacks (vulnerable), loggerheads (endangered), hawksbills (critically endangered), green sea turtles (endangered), Kemp’s Ridley (critically endangered), Olive Ridley (vulnerable), and flatback sea turtles (data deficient). What can you do to protect sea turtles?
- At night, keep bright lights off the beach to encourage sea turtles to nest and to ensure hatchlings can find their way to the sea.
- Keep beaches trash free to avoid turtles mistaking it for food or getting caught in plastic loops. Single use plastic bags are often mistaken by sea turtles for their favorite food, jellyfish. Consumption can cause them to suffocate.
- Join a coastal conservation effort working to protect sea turtle nests from predators.
- Of course you can always donate to MarineBio or join the MarineBio Conservation Society to help us share species information and raise awareness about the plight of endangered sea turtles. Whether you can spare $5 or $50, it will help us continue bringing the world a vast source of information on all things ocean.
Sea turtles have been making it to the top of the headlines recently, all positive for a change and I thought I would use this blog to draw attention to this. Additionally, I feel it’s always nice to give some attention to the turtles.
So the first piece of news, the secrets of the sea turtle migration have been uncovered. It turns out that the reproduction migration (females returning to their nesting beaches) is not the longest migration that sea turtles carry out. It has been found from the compilation of long term capture programs that the migration of immature turtles, termed “developmental migration”, is longer than the reproductive migration. Also this migration is only carried out once in their life time rather than every few years. On the migration topic as well, a study was carried out to determine the migration of juvenile leatherback sea turtles. However, due to the size and the weight of the juveniles it is impossible to attach a satellite tag to their shells without them sinking. So instead of following the hatchlings the scientists followed the currents. The “lost years” of a turtle’s life, the age between hatching and returning to foraging grounds can be anywhere between 3 to 5 years after they hatch. These years are the least understood part of a turtle’s life. Knowing more about where the turtles swim before they reach adulthood could be critical in protecting the species. Continue reading
Deepwater Horizon Oil Spill Proves Deadly for Sea Turtles in Gulf of Mexico
Oceana Releases New Report about Impacts of Oil on Sea Turtles and Threats to Populations
June 10, 2010
Contact: Dustin Cranor (firstname.lastname@example.org)
Oceana, the world’s largest international ocean conservation organization, released a new report today that finds the Deepwater Horizon oil spill extremely dangerous for sea turtles inhabiting the Gulf of Mexico. Specifically, sea turtles can become coated in oil or inhale volatile chemicals when they surface to breathe, swallow oil or contaminated prey, and swim through oil or come in contact with it on nesting beaches. Continue reading
I can’t tear myself away from the coverage of the Gulf oil tragedy. It seems the solution to stopping the flow is days if not weeks away. I wonder why oil tankers aren’t being used to contain the oil from the spill?
The loss of human lives was tragic. The impact on human lives will be tragic. What will be the impact on marine life? This couldn’t have happened at a worse time for some of the most fragile, and important, ecosystems and breeding grounds for Gulf species that are in the midst of spawning season. It’s spring in the Gulf. Spawning, migrating, incubating, hatching. It’s all happening now. I keep hearing about how this is going to impact seafood production for a decade. OK. Well, this is going to impact the very survival of some species forever. Including Homo sapiens.
International coalition advances marine conservation as part of the solution to climate change
WASHINGTON, Nov. 18 /PRNewswire-USNewswire/ — A large international coalition today urged the United States to support marine conservation options that will help mitigate climate change.
The ‘Blue Climate Coalition,’ comprised of sixty-six conservation groups and interests and over 150 marine scientists and professionals, from 33 countries, issued communications today addressed to President Obama and the United States Senate.
Together, the coalition letters request the option for marine conservation solutions to climate change to be considered in national climate change legislation and international climate change treaties, and support for marine science research that further explores this concept. Continue reading
