Animal communication involves a diversity of signals including visual displays, sounds and odours. Understanding the function of signals is difficult because humans cannot detect some signals such as UV light. This project investigates the functions of visual signals in two spider systems: the decorations in orb-webs and the colouration of crab spiders. We analyse whether these signals are cryptic or conspicuous. Do they attract prey or hide the spiders from predators? Our project will make a significant contribution to understanding the evolution of these signals, and will, at least in part, help resolve century old debates surrounding their function.

动物的交流涉及多种信号，包括视觉显示，声音和气味。理解信号的功能是困难的，因为人类无法检测到某些信号，如紫外线。本计画探讨视觉讯号在两种蜘蛛系统中的功能：圆网的装饰与蟹蛛的色彩。我们分析这些信号是隐蔽的还是明显的。它们是吸引猎物还是把蜘蛛藏起来躲避捕食者？我们的项目将为理解这些信号的演变做出重大贡献，并将至少部分地帮助解决围绕其功能的世纪老争论。
