Efficacy of multiple defences of mimics from the golden mimicry complex against two predators

Many prey species employ multiple defences during interactions with predators. Multiple defences can provide a selective advantage against a single predator at different stages of the interaction or attack, as well as against multiple predator types. However, the efficacy of multiple defences both during different sequences of an attack and against multiple predator types, remains poorly understood. We measured and classified defensive traits used by five mimics (Müllerian and Batesian) of the myrmecomorphic golden mimicry complex and one non-mimetic species. We then performed predatory trials using two different predators that differed markedly in their body size, trophic specialisation, and how they handle prey – one being an ant specialist (spider) and the other a generalist which avoided ants (skink). We identified 12 defensive traits and classified them into four groups (primary, chemical, mechanical, behavioural), which were strongly correlated. Skinks were much less likely to att..., The details are described in the Methods of the article., , # Efficacy of multiple defences of mimics from the golden mimicry complex against two predators

Give a brief summary of dataset contents, contextualized in experimental procedures and results.

## Description of the data and file structure

The file contains three spreadsheets: Servea includes data from experiment using Servea spiders; skink includes data from experiment using skinks, and traits includes defensive traits. The Servea sheet includes data on the size of spiders [mm], size of prey [mm], prey type. In each trial we recorded latency to attack (i.e., time [s] from orienting to prey to when they first pounced on prey), latency to capture (i.e., time [s] from the first attack to capture), number of attacks, and attack and capture frequencies. The skink sheet includes prey type, latency to spot (time [s] from prey release to when skink turned to see the prey), latency to approach (time [s] from spotting to when the skink started to move...

许多猎物种群在与捕食者的交互过程中会采用多种防御策略。多种防御手段可在交互或攻击的不同阶段，针对单一捕食者提供选择优势，同时也能应对多种捕食者类群。然而，目前学界对于多种防御策略在攻击的不同时序中、以及针对多种捕食者类群时的防御效能，仍知之甚少。

我们对蚁形拟态（myrmecomorphic）金色拟态复合体（golden mimicry complex）的5种拟态物种（含穆氏拟态（Müllerian mimicry）与贝氏拟态（Batesian mimicry）物种）以及1种非拟态物种所使用的防御性状进行了测量与分类。随后我们选取两种差异显著的捕食者开展捕食实验，二者在体型大小、营养特化程度以及猎物处理方式上均有不同：一种为蚁类专食性蜘蛛，另一种为避蚁的广食性石龙子（skink）。本研究共鉴定出12种防御性状，并将其划分为四大类（初级防御、化学防御、机械防御、行为防御），各类性状间存在显著相关性。石龙子的攻击概率显著更低[原文内容截断，详细实验细节参见论文方法部分]。

请结合实验流程与研究结果，对数据集内容进行简要概述。

## 数据与文件结构说明
本数据集包含三张电子表格：Servea工作表存储了使用Servea蜘蛛（Servea spider）开展的实验数据；skink工作表存储了石龙子捕食实验的数据；traits工作表则存储了防御性状相关数据。
Servea工作表包含蜘蛛体型（单位：毫米）、猎物体型（单位：毫米）以及猎物类型相关数据。每次实验中，我们记录了攻击潜伏期（即从蜘蛛定位猎物到首次扑向猎物的时间，单位：秒）、捕获潜伏期（即从首次攻击到成功捕获猎物的时间，单位：秒）、攻击次数以及攻击与捕获频率。
skink工作表包含猎物类型、发现潜伏期（即从释放猎物到石龙子转头看向猎物的时间，单位：秒）、接近潜伏期（即从发现猎物到石龙子开始移动的时间，单位：秒……[原文内容截断]）
