如果地球气候继续像科学家所预计的那样变暖,沿太平洋海岸的某些蟹类可能会面临灭绝。斯坦福大学海洋生物学家乔纳森·斯蒂尔曼所作的一项研究显示,生活在海滩边缘温暖海水中的小蟹无法忍受水温的升高。斯蒂尔曼对太平洋浅海水域发现的四种蟹对气温忍耐性进行了试验。其中两种蟹来自俄勒冈海岸,生活在水温为47华氏度-59华氏度的海水中。另外两种蟹来自墨西哥的加利福尼亚海湾,生活在54华氏度-86华氏度的海水中,实验中所用的这些蟹在属性上都可以被归称为瓷蟹。它们的体形较小,个头在1英寸～2英寸之间,通常生活在海滩边缘附近——被称为潮汐间栖息地。这些蟹具有净化水体的功能,可以吸取悬浮在海水中的颗粒。它们仅在高潮期间活跃。当退潮时,它们会躲藏在浅水中的岩石下。
Some of the crabs along the Pacific coast may face extinction if the earth’s climate continues to warm as scientists expect. A study by Jonathan Stillman, a marine biologist at Stanford University, shows that small crabs living in warm seawater on the edge of a beach can not tolerate rising water temperatures. Stillman tested the temperature tolerance of four species of crabs found in shallow Pacific waters. Two of the crabs come from the coast of Oregon and live in seawater that is 47 degrees Fahrenheit to 59 degrees Fahrenheit. The other two crabs come from the Gulf of Mexico in Mexico and live in sea water at 54 ° F and -86 ° F. The crabs used in the experiment can be categorized as porcelain crabs in nature. They are smaller, with heads between 1 and 2 inches and usually live near the edge of the beach - known as the tidal habitat. These crabs have the function of purifying the water and can draw particles suspended in seawater. They are only active during the climax. When low tide, they will hiding under the rocks in the shallow water.
