Data from: Biodiversity and habitat assessment of coastal benthic communities in a sub-Arctic industrial harbour area

General presentation This repository present the R codes ans associated data used in the article Biodiversity and habitat assessment of coastal benthic communities in a sub-Arctic industrial harbour area. Datasets include sampling information about the stations in Sept-Îles (Québec, Canada) sampled during three campaigns (2014, 2016, and 2017). Data includes density and taxonomy of benthic invertebrate species, with physico-chemical parameters and heavy metal concentrations at the surface of the sediment. The main research questions were to: describe coastal habitats and macrobenthic communities at Sept-Îles, in order to provide the first benthic ecological survey of the area evaluate the links between communities and abiotic variables (including heavy metals) detect the presence of similar benthic assemblages, along with their relationships with habitats evaluate how macrofaunal size range will influence community descriptions and relationships with habitat parameters Specific details Variables, units and files are explained in files README.yml (this file is a basic text file formatted with a YAML language) and README.txt. Language and software used for the analyses: R (4.0.2), PRIMER-E (6)

总体概述
本仓库收录了论文《亚北极工业港区沿海底栖生物群落的生物多样性与栖息地评估》中使用的R代码及配套数据集。数据集涵盖加拿大魁北克省七岛港（Sept-Îles）各采样站位的采样信息，采样工作分2014年、2016年、2017年三个航次开展。数据包含底栖无脊椎动物物种的密度与分类学信息，同时涵盖沉积物表层的理化参数及重金属浓度。本研究旨在解决以下核心科学问题：
1. 描述七岛港的沿海栖息地与大型底栖生物群落，完成该区域首次底栖生态本底调查；
2. 评估底栖生物群落与非生物变量（含重金属）之间的关联；
3. 识别区域内相似底栖生物组合的存在情况，并解析其与栖息地的关联；
4. 探究大型底栖动物的体型范围对群落描述及其与栖息地参数关联的影响。
