Abstract

Sea otters are keystone predators whose recovery and expansion from historical exploitation throughout their range can serve to enhance local biodiversity, promote community stability, and buffer against habitat loss in nearshore marine systems. Bioenergetics models have become a useful tool in conservation and management efforts of marine mammals generally, yet no bioenergetics model exists for sea otters. Previous research provides abundant data that can be used to develop bioenergetics models for this species, yet important data gaps remain. Here we review the available data that could inform a bioenergetics model, and point to specific open questions that could be answered to more fully inform such an effort. These data gaps include quantifying energy intake through foraging by females with different aged pups in different quality habitats, the influence of body size on energy intake through foraging, and determining the level of fat storage that is possible in sea otters of different body sizes. The more completely we fill these data gaps, the more confidence we can have in the results and predictions produced by future bioenergetics modeling efforts for this species.

海獭生物能模型的数据需求。
海獭是一种关键性食肉动物,它们在整个分布区从历史上的开发中恢复并扩大,可以提高当地的生物多样性,促进群落稳定,缓冲近岸海洋系统中栖息地的丧失。生物能模型已成为保护和管理海洋哺乳动物的有用工具,但目前还没有海獭的生物能模型。以往的研究提供了大量数据,可用于开发该物种的生物能模型,但仍存在重要的数据缺口。在此,我们回顾了可为生物能量学模型提供参考的现有数据,并指出了一些有待回答的具体问题,以便更全面地为这一工作提供参考。这些数据缺口包括:在不同质量的栖息地中不同年龄幼崽的雌性海獭通过觅食摄取能量的量化、体型对通过觅食摄取能量的影响,以及确定不同体型海獭可能的脂肪储存水平。我们越是全面地填补这些数据空白,就越能对该物种未来的生物能学建模工作所产生的结果和预测充满信心。

期刊介绍: Conservation Physiology is an online only, fully open access journal published on behalf of the Society for Experimental Biology. Biodiversity across the globe faces a growing number of threats associated with human activities. Conservation Physiology will publish research on all taxa (microbes, plants and animals) focused on understanding and predicting how organisms, populations, ecosystems and natural resources respond to environmental change and stressors. Physiology is considered in the broadest possible terms to include functional and mechanistic responses at all scales. We also welcome research towards developing and refining strategies to rebuild populations, restore ecosystems, inform conservation policy, and manage living resources. We define conservation physiology broadly and encourage potential authors to contact the editorial team if they have any questions regarding the remit of the journal.
