Hawaiian monk seals are one of the world\u2019s most endangered marine mammals. Only about 1,600 individuals still exist in the wild. They are threatened from multiple angles. Overhunting has decimated their historic population. Overfishing has threatened their food source. They\u2019re suffering from habitat loss and they\u2019re prime prey for sharks. Even marine debris can ensnare and kill them.<\/p>\n\n\n\n
In addition to these threats, there is another danger looming: The seals face an extreme <\/em>lack of genetic diversity.<\/p>\n\n\n\n \u201cGenetic variation is the raw material for adaptation to changing environments. If you lack genetic variation, you don\u2019t have (new) options available to you as the environment changes,” explained 51ÁÔÆæ Biological Sciences Professor Emily Latch.<\/p>\n\n\n\n Currently, she said, Hawaiian monk seals have among the lowest levels of genetic variation ever reported.<\/p>\n\n\n\n \u201cSo, they are in trouble,\u201d Latch concluded.<\/p>\n\n\n\n Luckily for the seals, Latch and her colleagues stood ready to help.<\/p>\n\n\n\n
