摘要

本研究通过信息理论和基于和谐度的框架探讨了蜘蛛网的结构复杂性,量化了不同网区蛛丝密度的空间格局,揭示了潜在的资源配置策略。目前,还没有标准化的方法来描述网的结构和复杂性,特别是对于单张网,这种方法允许对网的特征进行无损扫描和量化。通过分析蚕丝密度分布的熵,我们发现,当使用10个量化水平时,蚕丝密度分布的熵值遵循正态分布,平均值为1.24±0.22比特。在论文的第二部分,通过测量丝密度的谐波,我们发现给定点的丝密度可以从它的邻居中推断出来,平均谐波值为0.0039±0.0017(点云数据中总点的分数)。调和行为因其最大原则而引人注目,这表明网的最强部分出现在边界,与现有的蜘蛛网构造知识一致。这些发现提供了一种量化造网策略的新技术,并为蜘蛛的行为和进化提供了新的见解。

An analysis of silk density in spider webs.

This study explores the structural complexity of spider webs through information-theoretic and harmonicity-based frameworks to quantify spatial patterns in silk density across different web regions and reveal the underlying resource allocation strategies. Currently, there is no normalized approach for describing web structure and complexity, particularly for sheet webs, and this methodology allows for non-destructive scanning and quantification of web characteristics. By analysing the entropy of silk density distributions, a single scalar that captures the heterogeneity of material investment across the entire web, we observed that the entropy values follow a normal distribution with a mean of 1.24 ± 0.22 bits when using 10 quantization levels. In the second part of the paper, by measuring the harmonicity of the silk density, we reveal that the silk density at a given point can be inferred from its neighbours, with an average harmonicity value of 0.0039 ± 0.0017 (fraction of total points in point cloud data). The harmonic behaviour is notable for its maximum principle, suggesting that the strongest parts of the web appear at the boundaries, aligning with existing knowledge of spider web construction. These findings provide a new technique for quantifying web-building strategies and offer new insights into spider behaviour and evolution.
