  • Threats to Sea Turtles Artificial Lighting
    Threats to Sea Turtles Artificial Lighting Artificial lighting is a significant sea turtle conservation problem. Sea turtle hatchlings instinctively move towards the brightest light when they hatch – on a natural beach, this is the night sky over the ocean. The artificial lighting causes the hatchlings to become disoriented, and ultimately leads to their death. Below are two maps. The “Artificial Lighting” map is a satellite image of the lights that are visible at night in Florida from space. The “Florida County” map will be used for reference. You will also need your “Sea Turtle Nesting Data” from an earlier lesson. Directions: Using the data provided identify areas where artificial lighting has the greatest impact on sea turtle hatchlings. Artificial Lighting Map Lightly shaded areas (yellow) - Lights visible at night from space Compare the “Artificial Lighting” map with the blank county map below. Color in the counties which have the most visible night lights from space.

  • Threats to Sea Turtles and Possible Solutions (.Pdf)
    Threats to Sea Turtles and Possible Solutions Introduction Sea turtles are one of the most ancient reptiles in the world dating back some 110 million years ago, surviving the extinction of the dinosaurs. Their complex life cycle, covering several developmental habitats and migrations of hundreds or thousands of miles between feeding zones and nesting beaches, exposes them to many threats to their survival, both natural as well as anthropogenic (human induced), over a broad geographical area. Today, their populations have been drastically reduced so that all seven species of sea turtles in the world are considered threatened or in danger of extinction. Below you will find a description of the main natural threats and human activities that negatively impact sea turtles while offering some solutions and conservation measures to take. Natural Threats Over their existence of millions of years, sea turtles have survived various catastrophic climatic and geological changes, which have resulted in drastic changes to their distinct habitats. Furthermore, sea turtles, their nests and hatchlings (neonates) are faced with many habitual threats. While in the nest, the eggs and hatchlings face many predators like ants, crabs and raccoons. After leaving the nest, hatchlings encounter crabs, birds and a vast number of predators in the ocean (for example, fish and sharks). Very few, perhaps only one out of every 1,000 turtles hatched, will survive to maturity. As adults, the number of natural threats decreases significantly and they have very few natural predators, among them sharks and jaguars. However, it is the increase in negative human impacts that have caused these species to teeter on the brink of extinction, by placing additional pressure on every stage of their life cycle, Coatis preying on a green turtle nest in from nesting areas to mortality in the open Tortuguero, Costa Rica.

  • A New Direction for Sea Turtle Conservation

Traditional approaches have been unsuccessful at addressing the myriad threats that face sea tur- tles. The effectiveness of international agreements could be greatly increased through government enforcement of national and local laws that protect spe- cies and through increased cooperation and coordination. This Comment concludes that regional legislation in the European Community mandating habitat protection for listed species and local involvement in sea turtle pro- tection offers direction for future agreements seeking to protect sea turtles.

  • Ecology of Marine Turtles Under Climate Change
    Ecology of Marine Turtles under Climate Change Submitted by Kimberley Laura Stokes to the University of Exeter as a thesis for the degree of Doctor of Philosophy in Biological Sciences September 2014 This thesis is available for Library use on the understanding that it is copyright material and that no quotation from the thesis may be published without proper acknowledgement. I certify that all material in this thesis which is not my own work has been identified and that no material has previously been submitted and approved for the award of a degree by this or any other University. Kimberley L. Stokes Ecology of marine turtles under climate change Abstract Climate change threatens to disrupt biological systems around the globe, sparking debate over natural capacity for adaptation in a fragmented landscape. Marine turtles are evolutionarily ancient and have survived millions of years of prehistoric climate change, but are threatened by the rapidity of modern warming and a history of severe overexploitation that has left most populations depleted. This thesis explores a nesting aggregation of the green turtle (Chelonia mydas) in northern Cyprus, where a longitudinal programme of both intensive and extensive monitoring enables insight into individual and population level parameters and processes. Nesting on the two coastlines covered by this project is in the early stages of recovery, possibly in response to exhaustive nest protection efforts over the last twenty years. Saturation tagging at one key site allows us to confirm that recruitment of new breeders is an important driver of this trend, and that average clutch frequency has remained stable around three nests per female per year, validating nest-count derived abundance estimates at a regional scale.

  • Keeping Sea Turtles in the Dark
    Keeping Sea Turtles in the Dark Keeping Sea Turtles in the Dark This text is provided courtesy of the National Fish and Wildlife Foundation. Sea turtle hatchlings Funding boosts efforts to cut light pollution along Florida's nesting beaches Selling darkness in the Sunshine State can be tough. Florida's beach communities sparkle at night with homes and condominiums decked out with beautiful lighting systems. Beachside resorts and businesses depend on artificial lighting to ensure safety and entertainment for guests and customers at night. Wherever people live, work and play, nighttime lights follow. For decades, steadily increasing illumination along Florida's coasts has wreaked havoc on sea turtles, which rely on subtle, nighttime lighting cues to deposit eggs on beaches and make it safely to sea as hatchlings. By the early 1990s, Floridians committed to turtle conservation understood how tenuous the situation had become. Suzi Fox, director of the Anna Maria Island Turtle Watch, remembers the bad days on her island community on the Gulf of Mexico just south of Tampa. "There wasn't one half-block area in 7 miles where you could release a hatchling and have it go to the ReadWorks.org © 2019 National Fish and Wildlife Foundation. All Rights Reserved. Keeping Sea Turtles in the Dark sea," Fox said. "We didn't have any lighting ordinances back then, and people just didn't want to turn off their lights." Throughout the 1990s and early 2000s, Fox and her fellow turtle conservationists chipped away at light pollution in Florida, which hosts more than 90 percent of all sea turtle nesting in the continental United States.
