摘要
本研究通过模型模拟探讨了白蚁隧道中的食物运输效率(E),该隧道由一条主隧道和两条环形隧道组成。模拟白蚁通过具有相关概率(P1、P2、P3、P4)的分支节点(a、b、c、d)在主隧道和环形隧道之间航行。环形隧道的位置(δ)分别为:巢穴附近(δ = 1)、主隧道中心(δ = 2)和食物点附近(δ = 3)。结果显示,在δ = 1 时,a → d → b → c 和 c → d → b → a 等路径的 E 值较高。相反,当 δ = 2 时,P3 和 P4 的 E 值在 0.4 到 0.6 之间。对于 δ = 3,c → d 或 c → b 等路径显示出较高的 E 值,强调了环内分离隧道(以 P3 和 P4 为特征)在缓解交通拥堵方面的重要性。部分秩相关性验证了 P1 和 P2 对 E 的影响微乎其微,而 P3 和 P4 则对 E 有显著的负面影响,与 δ 无关。然而,当 δ = 2 时,由于环路隧道的位置对称性,P3 和 P4 的影响明显减弱。在讨论中,我们讨论了模型的局限性,并提出了克服这些局限性的策略。此外,我们还概述了潜在的实验验证,以确保全面了解隧道内白蚁食物运输的动力学规律。
Exploring the effects of two-segment loop tunnels on termite food transport efficiency: a simulation study.
This study explores the food transport efficiency (E) in a termite tunnel consisting of a main tunnel and a 2-segment loop tunnel through a model simulation. Simulated termites navigate between the main and loop tunnels through branching nodes (a, b, c, d) with associated probabilities (P1, P2, P3, P4). The loop tunnel locations (δ) are considered: near the nest (δ = 1), at the center of the main tunnel (δ = 2), and close to the food site (δ = 3). The results reveal that for δ = 1, paths such as a → d → b → c and c → d → b → a exhibited high E values. Conversely, for δ = 2, P3 and P4 demonstrate elevated E values ranging from 0.4 to 0.6. For δ = 3, paths like c → d or c → b display high E values, emphasizing the significance of in-loop separation tunnels (characterized by P3 and P4) in alleviating traffic congestion. Partial rank correlation validates that P1 and P2 minimally influence E, while P3 and P4 significantly negatively impact E, regardless of δ. However, for δ = 2, the influence of P3 and P4 is notably reduced due to the positional symmetry of the loop tunnel. In the discussion, we address model limitations and propose strategies to overcome them. Additionally, we outline potential experimental validations to ensure a comprehensive understanding of the dynamics governing termite food transport within tunnels.
