AI总结:

本研究通过引入资源介导的更高阶相互作用机制,探讨了种内竞争对岩-paper-scissors动态中物种共存和生物多样性的影响,揭示了其在局部图案形成与系统抗扩散能力之间的平衡作用。

摘要:

理解决定物种共存和生物多样性的机制是生态学中的根本挑战。本研究通过引入一种上下文相关的更高阶相互作用机制扩展了经典岩-paper-scissors模型,其中种内竞争由本地资源可用性动态调节。关键地,我们的定量分析揭示了更高阶相互作用显著调节系统结构组织:增强的更高阶相互作用导致空间波长减小,从而形成更紧凑的物种域。然而,这种结构变化使系统对移动性更敏感,将灭绝阈值移至更低值。这些发现突显了资源介导的更高阶调节的双重作用:它促进局部图案形成,但改变系统的抗扩散能力,为生物多样性保护提供了新的理论视角。

英文摘要:

Understanding the mechanisms that govern species coexistence and biodiversity represents a fundamental challenge in ecology. This study extends the classic rock-paper-scissors model by introducing a context-dependent higher-order interaction mechanism where intraspecific competition is dynamically regulated by local resource availability. Crucially, our quantitative analysis reveals that higher-order interactions significantly modulate the system's structural organization: Enhanced strength of higher-order interactions leads to a decrease in spatial wavelength, resulting in the formation of more compact species domains. However, this structural change makes the system more sensitive to mobility, shifting the extinction threshold to lower values. These findings highlight the dual role of resource-mediated higher-order regulation: it promotes local pattern formation but alters the system's resilience to dispersal, providing new theoretical perspectives for biodiversity conservation.
