Data includes species biomass, density and taxonomy of benthic macrofaunal species, with physico-chemical parameters at the sediment surface, biotic indicators and exposure indices.<br><br> The main research questions were to: <ol> <li>model the exposure of benthic ecosystems to anthropogenic activities locally</li> <li>explore the links between benthic community diversity and anthropogenic exposure</li> </ol> <hr> <h3> Specific details</h3> <ul> <li>Variables, units and files are explained in files <strong>README.yml</strong> (this file is a basic text file formatted with a YAML language) and <strong>README.txt</strong>.</li> <li>Language and software used for the analyses: R (4.2), PRIMER-E (6)</li> </ul> <hr>

Dreujou, Elliot; Christopher W McKindsey; Cindy Grant; Lisa Tréau de Coeli; Richard St-Louis; Philippe Archambault — 2020-08-27 <h3>General presentation</h3> This repository present the R codes ans associated data used in the article <em>Biodiversity and habitat assessment of coastal benthic communities in a sub-Arctic industrial harbour area</em>.<br><br> 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.<br><br> The main research questions were to: <ol> <li>describe coastal habitats and macrobenthic communities at Sept-Îles, in order to provide the first benthic ecological survey of the area</li> <li>evaluate the links between communities and abiotic variables (including heavy metals)</li> <li>detect the presence of similar benthic assemblages, along with their relationships with habitats</li> <li>evaluate how macrofaunal size range will influence community descriptions and relationships with habitat parameters</li> </ol> <hr> <h3>Specific details</h3> <ul> <li>Variables, units and files are explained in files <strong>README.yml</strong> (this file is a basic text file formatted with a YAML language) and <strong>README.txt</strong>.</li> <li>Language and software used for the analyses: R (4.0.2), PRIMER-E (6)</li> </ul> <hr>
