Abstract

Ecological and genetic interactions among conspecific populations play an important role in population viability, but these interactions are not always fully considered in strategies to recover endangered taxa. Southern Resident killer whales are a high-profile population listed as endangered by both the United States and Canada. Risks to the population are well known, and include insufficient prey, inbreeding depression, disturbance, and environmental contaminants. Here, we argue that a fifth factor-interactions with other sympatric killer whale populations-plays an underappreciated role in the population's current and potential status. Based on studies conducted over the past two decades, we illustrate that consumption of shared prey, behavioral interactions in shared habitat, and shared DNA through potential interbreeding with other populations will strongly influence the future trajectory of the Southern Resident killer whales.

观点：南方虎鲸的未来取决于与其他虎鲸种群的相互作用。

同种种群间的生态和遗传相互作用在种群生存力中起着重要作用，但这些相互作用在濒危分类群的恢复策略中并未得到充分考虑。南方虎鲸被美国和加拿大列为濒危物种。对种群的风险是众所周知的，包括猎物不足、近亲繁殖抑制、干扰和环境污染。在这里，我们认为第五个因素——与其他同域虎鲸种群的相互作用——在种群的当前和潜在状态中起着被低估的作用。基于过去二十年的研究，我们说明了共享猎物的消耗，共享栖息地的行为互动，以及通过与其他种群的潜在杂交共享DNA，将强烈影响南方居住虎鲸的未来轨迹。

期刊介绍： Ecology and Evolution is the peer reviewed journal for rapid dissemination of research in all areas of ecology, evolution and conservation science. The journal gives priority to quality research reports, theoretical or empirical, that develop our understanding of organisms and their diversity, interactions between them, and the natural environment. Ecology and Evolution gives prompt and equal consideration to papers reporting theoretical, experimental, applied and descriptive work in terrestrial and aquatic environments. The journal will consider submissions across taxa in areas including but not limited to micro and macro ecological and evolutionary processes, characteristics of and interactions between individuals, populations, communities and the environment, physiological responses to environmental change, population genetics and phylogenetics, relatedness and kin selection, life histories, systematics and taxonomy, conservation genetics, extinction, speciation, adaption, behaviour, biodiversity, species abundance, macroecology, population and ecosystem dynamics, and conservation policy.
