The role of high-contrast male facial stripes in mitigating female aggression in the jumping spider, Plexippus paykulli

Vibrant male coloration and energetic courtship displays set jumping spiders apart from most arachnids, which typically rely on non-visual stimuli. Like many other spiders, female salticids engage in sexual cannibalism, making courtship a risky but necessary endeavor for males. In this study, we investigated the relationship between male coloration and female aggression to better understand the interplay of attraction and aversion during courtship. Many male jumping spiders sport conspicuous coloration or high-contrast patterns that are reminiscent of the coloration of many aposematic insects. The faces of Plexippus paykulli males are adorned with bold vertical stripes they direct toward females during courtship. We hypothesized that these stripes could function as a sensory trap, leveraging female aversion to the signal to reduce the likelihood of cannibalism. We tested whether spiders exhibit an aversion to stripes in the context of predation by manipulating prey coloration and testin..., , , # Title of Dataset: The role of high-contrast male facial stripes in mitigating female aggression in the jumping spider, Plexippus paykulli *** ## Description of the Data and file structure # 'expt1\_prey\_choice.csv' & 'expt1\_prey\_choice\_x2.csv' These datasheets contain the same data but are formatted differently for analyses we performed in R. The spreadsheet, 'expt1\_prey\_choice.csv' is a long format wherein each trial (represented by 'spider\_id') has two rows (one for each prey treatment, Grey or Striped). The other has a single row per trial and the chosen prey is listed under 'chosen\_treatment'. Variable descriptions by column (expt1\_prey\_choice.csv'): spider\_id - unique identifier for spiders used in trials (also serves as Trial ID since no spiders were used repeatedly) treatment - color treatment applied to termite prey (Grey or Striped) choice\_binary - Yes/no outcome of trial (1 = Yes, indicating the spider struck the termite treatment indicated (grey or stri...鲜艳的雄性体色与充满活力的求偶行为，使得跳蛛区别于绝大多数依赖非视觉刺激的蛛形纲动物。与多数蜘蛛一致，雌性跳蛛存在性食同类行为，这令雄性的求偶成为一项高风险却又不可或缺的尝试。本研究旨在探究雄性体色与雌性攻击性之间的关联，以更深入地理解求偶过程中吸引力与厌恶感的相互作用。 诸多雄性跳蛛拥有醒目的体色或高对比度斑纹，其样式与诸多警戒色昆虫的体色极为相似。复孔跳蛛（*Plexippus paykulli*）雄性的面部带有醒目的垂直条纹，它们会在求偶过程中向雌性展示此类条纹。我们提出假说：这些条纹可作为一种感官陷阱，借助雌性对该信号的厌恶感降低其被同类相食的概率。 我们通过操纵猎物体色并开展相关测试，以探究蜘蛛在捕食情境下是否会对条纹产生厌恶反应。# 数据集标题：高对比度雄性面部条纹在减缓跳蛛（*Plexippus paykulli*）雌性攻击性中的作用 # 数据与文件结构说明 "expt1_prey_choice.csv" 与 "expt1_prey_choice_x2.csv" 这两份数据表包含完全一致的实验数据，但为适配我们在R语言中开展的分析采用了两种不同的格式。其中"expt1_prey_choice.csv"为长格式数据，每个以`spider_id`标识的实验试次（trial）包含两行数据（分别对应灰色或条纹两种猎物处理组）；另一份文件则为单试次单行格式，实验中被选中的猎物处理组将在`chosen_treatment`字段中列明。 以下为"expt1_prey_choice.csv"各列的变量说明： `spider_id`：实验所用蜘蛛的唯一标识符（由于每只蜘蛛仅参与一次实验，因此同时也可作为实验ID） `treatment`：施加于白蚁猎物的颜色处理组（灰色或条纹） `choice_binary`：实验的二元结果（1代表“是”，即蜘蛛攻击了对应颜色处理组的白蚁——原文此处有截断）
