Range-wide occurrence records of the subarctic copepod Calanus finmarchicus and associated environmental predictor variables

This dataset contains occurrence records and associated metadata for the zooplankton species Calanus finmarchicus that were compiled from multiple open access databases. A file containing the corresponding background points is provided, along with gridded environmental variables for each season (Jan-Feb-Mar, Apr-May-Jun, Jul-Aug-Sep, Oct-Nov-Dec) and era (1955-1984, 1985-2017) that were assessed in this study. Together these data were used as input files for the MaxEnt ecological niche model within the peer reviewed article: Freer JJ, Daase, M, Tarling GA, (2021) Modelling the biogeographic boundary shift of Calanus finmarchicus reveals drivers of Arctic Atlantification by subarctic zooplankton, Global Change Biology. Finally, an R Markdown document is provided to enable data users to replicate the model optimisation and prediction steps using the input data files within this repository.

Statement

Occurrence records represent those remaining after undertaking quality assurance and control processes as detailed in section 6. Further actions to limit the potential for sampling bias issues were carried out and are included in the R Markdown file we provide.

Due to limited data availability, seasonal environmental data during the older time period (1955-1984) are limited to: bathymetry, slope, temperature, salinity, sea-ice concentration and current velocity.

Sensitivity analyses were carried out to (a) account for potential misidentification of occurrences between Calanus finmarchicus and its congener, C. glacialis, (b) account for potential bias stemming from the seasonal assignment process of occurrences to environmental, and (c) test the sensitivity of model outputs to the inclusion of sea-ice concentration. Code for these analyses is within the R Markdown file we provide.
