Resource manipulation reveals interactive phenotype-dependent foraging in free-ranging lizards

Recent evidence suggests that individuals differ in foraging tactics and this variation is often linked to an individual’s behavioural type (BT). Yet, while foraging typically comprises a series of search and handling steps, empirical investigations have rarely considered BT-dependent effects across multiple stages of the foraging process, particularly in natural settings.
In our long-term sleepy lizard (Tiliqua rugosa) study system, individuals exhibit behavioural consistency in boldness (measured as an individual’s willingness to approach a novel food item in the presence of a threat) and aggressiveness (measured as an individual’s response to an ‘attack’ by a conspecific dummy). These BTs are only weakly correlated and have previously been shown to have interactive effects on lizard space use and movement, suggesting that they could also affect lizard foraging performance, particularly in their search behaviour for food.
To investigate how lizards’ BTs affect their foraging process i..., The data included in this manusript combines several sources of information from our field site at Bundy Bore, Australia.

The most central dataset for this paper is the lizard visit documentation, obtained by camera-traps recording in a time-lapse mode, the dataset is included here in a cleaned form, after removing irrelevant lines (e.g. non lizard visit) and colunms. 
Behavioral data with repeated assays on individual lizards. This data is included in the recent paper by Payne et al. (2021) Animal Behaviour; as well as in the dataset cited below.
GPS tracking data for estimating Home Range (HR) size for focal lizards. This is used as a predictor in relevant models. HR . Information on the HR results is aviaible in the included dataset and a broader version that includs several years and not only this particualr one was included in Payne et al. (2022) Ecological Monographs
Code for the modeling is included as well, see readme for more details.

Below we describe three data sets that were used in the statistical analysis for the paper *Resource manipulation reveals interactive phenotype-dependent foraging in free-ranging lizards* published in *Journal of Animal Ecology*.

These datasets are used in the R script titled **data_analysis_SleepyForaging** which provides R code to reproduce the analysis.

The provided data is cleaned and collated from several raw datasets including GPS data of lizard tracks, camera trap observations, and lizard biometrics. If you would like any of the raw, unprocessed data please contact Orr Spiegel ([[e-mail]](mailto:[e-mail])) or Marcus Michelangeli ([[e-mail]](mailto:[e-mail])).

### Brief description of the study design and the type of data collected

We investigated how a lizard’s behavioral type (boldness and aggressiveness), ...

近期研究表明，不同个体的觅食策略存在差异，且该变异通常与个体的行为型（behavioural type, BT）相关。然而，尽管觅食过程通常包含一系列搜寻与处理步骤，但实证研究极少考虑行为型对觅食过程多个阶段的影响，在自然环境中更是如此。

在我们针对蓝舌石龙子（Tiliqua rugosa）的长期研究体系中，个体在大胆性（boldness，以个体在威胁存在时接近新奇食物的意愿为衡量指标）与攻击性（aggressiveness，以个体对同种模型“攻击”的反应为衡量指标）上表现出行为一致性。这两类行为型仅呈弱相关，且既往研究已证实它们会对石龙子的空间利用与移动产生交互效应，提示二者亦可能影响石龙子的觅食表现，尤其是在食物搜寻行为方面。

为探究石龙子行为型如何影响其觅食过程……本手稿所纳入的数据整合了澳大利亚邦迪泉（Bundy Bore）野外站点的多类信息来源。

本研究最核心的数据集为石龙子到访记录文档，由采用延时拍摄模式的相机陷阱获取。本数据集已完成清洗，移除了无关行（如非石龙子到访记录）与列，现随本文一并提供。

针对个体石龙子的重复行为测定数据集。该数据已收录于Payne等人（2021）发表于《动物行为（Animal Behaviour）》的研究中，同时也包含于下文引用的数据集中。

用于估算目标石龙子家域（Home Range, HR）面积的GPS追踪数据集，该数据可作为相关模型的预测变量。本数据集已收录家域分析结果，而包含多年数据（而非仅本研究时段）的更完整数据集则发表于Payne等人（2022）的《生态学专论（Ecological Monographs）》中。

建模所用代码亦随附于本数据集，详细信息请参阅README文件。

下文将介绍发表于《动物生态学杂志（Journal of Animal Ecology）》的论文《Resource manipulation reveals interactive phenotype-dependent foraging in free-ranging lizards》（《资源操控揭示自由活动石龙子的表型依赖型交互觅食策略》）的统计分析所用的三类数据集。

这些数据集将用于名为**data_analysis_SleepyForaging**的R脚本，该脚本包含可复现本次分析的R代码。

本数据集已从多个原始数据集清洗整合而来，原始数据包括石龙子轨迹GPS数据、红外相机观测记录以及石龙子生物测量数据。若需获取任何未经处理的原始数据，请联系奥尔·施皮格尔（[e-mail]）或马库斯·米凯兰杰利（[e-mail]）。
