許多龜類、鱷魚、喙頭蜥及其他爬行動物在產卵後，其後代的性別會由孵化溫度決定。隨著全球氣溫上升，一些物種正面臨愈加嚴重的性別比例失衡，甚至可能出現整代個體皆為單一性別的情況。有些物種試圖透過提前築巢或選擇不同的棲地來適應，但也有物種因繁殖性別失衡而面臨滅絕風險。
Many turtles, crocodilians, tuatara, and other reptiles rely on temperature‑based sex determination. As global temperatures rise, some species face increasingly skewed sex ratios, potentially leading to entire generations being dominated by a single sex. Some species are attempting to adapt by nesting earlier or choosing different habitats, but others face extinction risks due to these reproductive imbalances.
