背景知识

高温和性别，这听上去好像没什么联系，但对海龟来说，情况远不是如此。全球变暖正在加剧美国佛罗里达州海龟种群日益严重的性别失衡。据《卫报》4日报道，过去4年，佛州夏季温度连创新高，导致海滩上几乎每只新出生的海龟都是雌性。

Global heating means almost every sea turtle in Florida now born female

全球变暖意味着佛罗里达几乎每只海龟出生时都是雌性

Nearly every sea turtle born on the beaches of Florida in the past four years has been female according to scientists. The spike in female baby turtles comes as a result of intense heatwaves triggered by a growing climate crisis that is significantly warming up the sands on some beaches as CNN reported this week. According to the National Ocean Service if a turtle’s eggs incubate below 27C (82F) the turtle hatchlings will be male. If the eggs incubate above 31C (89F) the hatchlings will be female. Temperatures that waver between the two extremes will result in a mix of male and female baby turtles.

科学家称，过去四年在佛罗里达海滩出生的海龟几乎都是雌性的。据美国有线电视新闻网（CNN）本周报道，日益严重的气候危机引发了强烈的热浪，导致一些海滩上的沙子明显变暖，雌性小海龟数量的激增。根据美国国家海洋局的说法，如果海龟的蛋在27摄氏度(82华氏度)以下孵化，孵化出来的海龟将是雄性。如果在31摄氏度(89华氏度)以上将蛋孵化出来，则孵化出的幼崽将是雌性。在两个极端之间摇摆不定的温度会导致小海龟雌性和雄性相混合。

Researchers also discovered that the warmer the sand the higher the ratio of female turtles. “As the Earth experienced climate change increased temperatures could result in skewed and even lethal incubation conditions which would impact turtle species and other reptiles ” the National Ocean Service said. In a statement to Reuters Bette Zirkelbach manager of the Turtle Hospital in Marathon Florida Keys said: “The frightening thing is the last four summers in Florida have been the hottest summers on record.”

研究人员还发现，沙子越温暖，雌性海龟的比例越高。美国国家海洋局表示:“随着地球经历气候变化，温度上升可能导致扭曲甚至致命的孵化条件，这将影响海龟物种和其他爬行动物。” 佛罗里达群岛马拉松市海龟医院的经理贝蒂·泽克巴什在给路透社的一份声明中说:“可怕的是，过去4个夏天是佛罗里达州有记录以来最热的夏天。”

She added: “Scientists that are studying sea turtle hatchlings and eggs have found no boy sea turtles so only female sea turtles for the past four years.” The uneven male-to-female ratio is a growing concern among scientists who worry that the sea turtle population will eventually become stunted.

她补充说:“研究海龟幼崽和海龟蛋的科学家没有发现雄性海龟，所以在过去的四年里只有雌性海龟。” 科学家们越来越担心海龟的性别比例失衡，他们担心海龟的数量最终无法充分增长。
