  "account": "Moving threatened sea turtle nests to safer locations can protect the eggs from rising tides and extreme heat, but a new study reveals that this conservation method may have unforeseen consequences for the hatchlings that emerge. Researchers from UNSW studied 48 green turtle nests over two nesting seasons on Heron Island, a southern Great Barrier Reef location. They compared natural nests with those relocated under shade cloth and those left unshaded.\n\nIncubation temperature determines hatchling sex, and unshaded relocated nests were significantly hotter and produced predominantly female hatchlings. Just 8% of the hatchlings sampled in one season were estimated to be male. Shading the relocated nests reduced temperatures and produced a more balanced sex ratio. However, even when shaded relocated nests reached the same temperature as natural nests, they had lower hatching success, and the hatchlings were smaller and less capable of righting themselves when flipped.\n\nLead author Davey Dor, a sea turtle ecologist at UNSW, stated that the difference in outcomes remains even when shaded and natural nests are the same temperature. He suggested that factors such as moisture, sand conditions, gas exchange, microbes, and nest depth could be contributing to these effects. The researchers are now investigating which factors are influencing hatchling development.\n\nWhile the findings emphasize that nest relocation as a conservation strategy is crucial, Dor emphasized the need to understand these factors to provide the turtles with the best possible chance of survival.",
