Ecology of eastern and southern festoons: dataset and software

The dataset contains the R script used to explore the differences between ecological niches of eastern (Zerynthia cerisy) and southern festoon (Zerynthia polyxena) and the species observation points from GBIF and Biologer databases. The raster files used to extract variables of interest are not included, but are freely available online. Follow the R script for detailed methodology and read the paper entitled "Ecology of eastern and southern festoons: living in a city or thriving in semi-natural areas?" for more details. The study demonstrated eastern festoon preference towards the urban environments, that provides similar ecological niche compared to the original habitats found in Mediterranean. On the other hand, southern festoon is found in more natural environments that resemble species natural habitats found along the river banks in the temperate regions of Europe and Asia.本数据集包含用于探究东方缀凤蝶（Zerynthia cerisy）与南缀凤蝶（Zerynthia polyxena）生态位差异的R脚本（R script），以及源自GBIF与Biologer数据库的物种观测点位数据。用于提取目标变量的栅格文件未包含在本数据集中，但可在线免费获取。请参考本R脚本以获取详细研究方法，如需了解更多细节可查阅题为"东方与南缀凤蝶的生态学：栖居于城市还是繁盛于半自然区域？"的研究论文。本研究表明，东方缀凤蝶偏好城市环境，该类环境与其在地中海区域的原生栖息地生态位特征相似。与之相反，南缀凤蝶则多见于更贴近其自然原生栖息地的生境中，这类生境与欧亚温带区域河岸带的物种天然栖息地特征相符。
