Global warming will cause less offspring of hawksbill turtles in Brazil
“Climate change is expected to impact animals that are heavily reliant on environmental factors, such as sea turtles, since the incubation of their eggs, hatching success and sex ratio are influenced by the environment in which eggs incubate. As climate change progresses it is therefore important to understand how climatic conditions influence their reproductive output…

Unmanned aerial vehicles (UAVs) are being used to monitor nesting population of green turtles
“Nester abundance is a key measure of the performance of the world’s largest green turtle rookery at Raine Island, Australia, and has been estimated by mark-resight counts since 1984. Nesters are first marked by painting their carapace with a longitudinal white stripe. Painted and unpainted turtles are then counted by a surface observer on a…

Sea turtles react to plastic smell as if it were food
“Plastic debris is rapidly accumulating in the oceans. Nearly 700 species of marine animals, including endangered megafauna like sea turtles and whales, are threatened by plastic debris through ingestion and entanglement. Despite the ubiquity of this threat, little is known about the sensory mechanisms that drive wildlife to interact with plastic debris. Recent findings suggest…

Global Warming causes more females than males to be born (in sea turtles)
“ Climate change affects species and ecosystems around the globe. The impacts of rising temperature are particularly pertinent in species with temperature-dependent sex determination (TSD), where the sex of an individual is determined by incubation temperature during embryonic development. In sea turtles, the proportion of female hatchlings increases with the incubation temperature. With average global…
