摘要

我们提出了一个中性群落的统计物理模型，其中每个代理可以代表垂直方向上生长的相同植物物种，它们在阳光下以 "富者愈富 "的竞争形式生长。在这个生态系统中加入的干扰会使一个代理从最低的生长水平重新开始，这种干扰是以随机重置的形式实现的。我们的研究表明，在这个竞争足够激烈的模型中，以希尔数家族为特征的垂直多样性会在中间干扰时稳健地出现局部最大值。

Emergence of vertical diversity under disturbance

We propose a statistical physics model of a neutral community, where each agent can represent identical plant species growing in the vertical direction with sunlight in the form of rich-get-richer competition. Disturbance added to this ecosystem, which makes an agent restart from the lowest growth level, is realized as a stochastic resetting. We show that in this model for sufficiently strong competition, vertical diversity characterized by a family of Hill numbers robustly emerges as a local maximum at intermediate disturbance.

期刊介绍： Physical Review E (PRE), broad and interdisciplinary in scope, focuses on collective phenomena of many-body systems, with statistical physics and nonlinear dynamics as the central themes of the journal. Physical Review E publishes recent developments in biological and soft matter physics including granular materials, colloids, complex fluids, liquid crystals, and polymers. The journal covers fluid dynamics and plasma physics and includes sections on computational and interdisciplinary physics, for example, complex networks.
