对西阿留申群岛有和没有海獭种群的比较表明，该物种对于确定滨海和亚滨海群落结构很重要。海獭控制草食性无脊椎动物种群。海獭的清除会导致食草动物增加，并最终导致大型植物群落的破坏。观察结果表明，海獭的重建间接影响了与大型植物初级生产力相关的岛屿动物群。
A comparison of western Aleutian Islands with and without sea otter populations shows that this species is important in determining littoral and sublittoral community structure. Sea otters control herbivorous invertebrate populations. Removal of sea otters causes increased herbivory and ultimately results in the destruction of macrophyte associations. The observations suggest that sea otter reestablishment indirectly affects island fauna associated with macrophyte primary productivity.
