长寿是一种由自然选择形成的生命史特征。一个尚未探索的结果是，对这一特性的选择如何影响物种组合的多样性和多样化。在北太平洋多样化的岩鱼（sebases）组合的激励下，研究了寿命与竞争能力之间权衡的影响。建立了一个竞争模型，并用于探索物种多样化和共存的潜力。入侵分析强调，寿命的生活史特征权衡可以减轻竞争能力的影响，有利于有限数量物种的共存。我们的研究结果对多物种相互作用中的生态位分化、限制相似性和组装动力学具有启示意义。
Longevity is a life-history trait that is shaped by natural selection. An unexplored consequence is how selection on this trait affects diversity and diversification in species assemblages. Motivated by the diverse rockfish (Sebastes) assemblage in the North Pacific, the effects of trade-offs in longevity against competitive ability are explored. A competition model is developed and used to explore the potential for species diversification and coexistence. Invasion analyses highlight that life-history trait trade-offs in longevity can mitigate the effects of competitive ability and favour the coexistence of a finite number of species. Our results have implications for niche differentiation, limiting similarity and assembly dynamics in multispecies interactions.
