如何维持生态系统的生物多样性是生态学领域的一个长期问题。在此，我提出了一个新的共存理论，即生物节律的多样性。昼夜节律、月周节律和年周节律控制着生物体的短期和长期活动，被认为是生物体中的普遍现象。理论食物网的分析表明，不同的生物周期在维持复杂的群落中起着关键作用。每一种生物节律都不具有独立的强大稳定作用，但与其他节律结合时，会增强群落的持久性。生物节律也减轻了由食物网复杂性引起的内在不稳定趋势。由于多个活动周期的混杂而产生的时间弱相互作用对共存起着关键作用。生物活动响应地球自转的多节律变化可能是维持生物群落的一个关键因素。
How ecosystem biodiversity is maintained remains a persistent question in the field of ecology. Here, I present a new coexistence theory, i.e. diversity of biological rhythm. Circadian, circalunar and circannual rhythms, which control short- and long-term activities, are identified as universal phenomena in organisms. Analysis of a theoretical food web with diel, monthly and annual cycles in foraging activity for each organism shows that diverse biological cycles play key roles in maintaining complex communities. Each biological rhythm does not have a strong stabilizing effect independently but enhances community persistence when combined with other rhythms. Biological rhythms also mitigate inherent destabilization tendencies caused by food web complexity. Temporal weak interactions due to hybridity of multiple activity cycles play a key role toward coexistence. Polyrhythmic changes in biological activities in response to the Earth's rotation may be a key factor in maintaining biological communities.
