Abstract:
In altricial mammals, the mother’s care and attendance are essential for the young to acquire survival skills. Not much is known about mother-pup behavior in the sea otter population of Simpson Bay, Prince William Sound, Alaska, United States. In these studies, firstly, water depth and location of feeding females with pups of different ages were recorded (global positioning system [GPS] locations of the sea otters are given in the map). Secondly, boat locations were noted when females with pups were observed for 24 hour activity budgets (GPS locations of the boat are given in the map). Weather, time and tidal conditions were also recorded and tested on the influence on sea otters behavior.

摘要：
晚成哺乳动物的母兽抚育与照料是幼崽获得生存技能的必要前提。目前针对美国阿拉斯加州威廉王子湾辛普森湾海獭种群的母崽行为研究仍较为匮乏。本研究首先记录了抚育不同年龄段幼崽的雌性海獭的活动水深与位置信息（海獭的全球定位系统（GPS）坐标已标注于地图中）；其次，在对带崽雌性海獭开展24小时活动预算观测时，记录了观测船只的位置（船只的GPS坐标已标注于地图中）。此外还同步记录了天气、时间与潮汐条件，并检验了上述因素对海獭行为的影响。
