Variation in Environmental Conditions and Biodiversity Between Contrasting Intertidal Habitats Across Multiple Spatial Scales on European Rocky Shores

This dataset accompanies the study **“Variations in environmental conditions and biodiversity between contrasting intertidal habitats at multiple spatial scales across European rocky shores.”** Intertidal rocky shores experience strong environmental variability, and habitat-forming canopy algae can modulate local microclimate and light exposure, potentially altering community structure and biodiversity. The files documented below integrate daily aggregated environmental measurements (**temperature** and **light intensity**) with biodiversity metrics (**alpha diversity** and **beta dispersion**) across multiple spatial scales (plot, area, and site) in two European regions (NE Atlantic and Western Mediterranean). Resampling procedures (bootstrap/permutation) are included to estimate region-scale effects and generate null expectations for habitat differences.

本数据集为下述研究的配套数据资源：**《欧洲岩质潮间带多空间尺度下不同潮间生境的环境条件与生物多样性差异》**。岩质潮间带环境变异性极强，作为生境构建者的冠层藻类可调节局地微气候与光照暴露水平，进而可能改变群落结构与生物多样性。下述记录的数据集文件整合了每日汇总的环境测量数据（**温度**与**光照强度**）与生物多样性指标（**α多样性（alpha diversity）**与**β离散度（beta dispersion）**），覆盖欧洲东北大西洋（NE Atlantic）与西地中海（Western Mediterranean）两个区域内的多空间尺度，包括样地（plot）、区域（area）与样点（site）。本数据集还包含重采样流程（bootstrap/置换检验），用于估算区域尺度效应并为生境差异生成零假设预期值。
