With a team of collaborators, we tested new specially-designed prototypes of Lotek microsatellite tags on 160 juvenile sea turtles of four species in the North Atlantic. The data from these tags was published in a new article, "Novel Microsatellite Tags Hold Promise for Illuminating the Lost Years in Four Sea Turtle Species." We sat down with lead-author Tony Candela to talk about this article, his process as lead-author, and the important implications of these findings for the bio-logging community.
When fishermen and researchers collaborate, they create opportunities to amplify efforts for the research and conservation of sea turtles. This past spring, Upwell participated in these efforts by providing a satellite tag for Liam Neythan, a leatherback sea turtle that was saved in Sinaloa, Mexico. Our collaborators, the fishers Edmundo Rafael Garcías Burgos and Mariano García Olivas, as well as Dr. Alan Zavala Norzagaray and the CIIDIR IPN Unidad Sinaloa are the key collaborators and heroes in this story.
Upwell Research Project Technician Sierra Fullmer shares some of her most exciting sightings while conducting aerial surveys to look for leatherbacks off of the US West Coast.
Most sea turtle species migrate and spend large amounts of their life history in areas of the ocean considered “high seas.” The high seas are the parts of the ocean that are not under the jurisdiction of any nation. In June of 2023, after almost two decades of negotiations, UN Member states adopted the Biodiversity in Areas Beyond National Jurisdiction treaty (also known as the High Seas Treaty) to provide a coherent and holistic framework for protecting the high seas. Earlier this month, Upwell Executive Director Dr. George Shillinger attended the High Seas Treaty symposium to learn more about how its implementation may impact sea turtle populations and to seek opportunities to further the protection of turtles at sea.
The new publication "Incorporating multidimensional behavior into a risk management tool for a critically endangered and migratory species," takes a look at how data on leatherback diving behavior can be used to improve the South Pacific TurtleWatch tool aimed at reducing bycatch.
New technologies are finally shedding light on one of the greatest mysteries in sea turtle biology. Using prototype “micro-satellite” tags specifically designed to fit juvenile leatherback turtles, Upwell and Florida Atlantic University researchers released eighteen captive reared juvenile leatherbacks to track their movements off the coast of Florida and shed light on the “lost years” phase of their lives.
Data collected at nesting beaches give us only a brief glimpse into sea turtles’ intricate life histories. Satellite tags are one of the best tools available to collect data on sea turtle movements and behaviors in marine habitats. But where tags are deployed matters. Deploying tags at nesting beaches means we are limiting our research scope to the females within a population that are nesting in a given year.
You might not think of someone behind a desk as working on the frontlines of sea turtle conservation, but Upwell’s Oceanographic Researcher, Tony Candela is doing just that. Tony is incorporating mathematics and oceanography to simulate the movements of hatchling and juvenile sea turtles to advance protections for them at sea.
