Abstract

This step links cleaned GBIF occurrences to climatology to quantify species- and community-scale thermal affinities. Occurrence points are spatially thinned to reduce sampling bias, paired with WorldClim SST (bio6) to derive per-taxon species thermal indices and latitudinal envelopes, then joined to multi-year community matrices to compute CTI metrics (means and confidence bounds) for each sample.

This is one of four datasets in the BCO-DMO catalog that were produced with the "Fourchon Nekton Turnover Workflow" (v1.0.0, doi: https://doi.org/10.5281/ZENODO.18165331). BCO-DMO hosts the datasets and supplemental data produced by this workflow that have had minor modifications to enhance the interoperability of the data and were imported into the BCO-DMO data system (See more in section "BCO-DMO Processing"). The workflow contains the exact formats of the data files produced and used by the workflow scripts. The workflow contains scripts, configurations, readme files, and input/output files for four stages listed below. Each workflow stage corresponds to a BCO-DMO dataset (See "Related Datasets" section on the BCO-DMO pages).

"Fourchon Nekton Turnover Workflow" steps with corresponding BCO-DMO dataset IDs:

"1_raw_data" = includes raw drop-sampling data corresponding to BCO-DMO dataset 991168 (doi: 10.26008/1912/bco-dmo.991168.1)
"2_gbif_workflow" = includes GBIF species observation data corresponding to metadata in BCO-DMO dataset 991175 (doi: 10.26008/1912/bco-dmo.991175.1)
"3_CTI_calculations" = includes community temperature index (CTI) data corresponding to BCO-DMO dataset 941250 (doi: 10.26008/1912/bco-dmo.941250.1)
"4_species_of_interest" = includes the results of a species pool analysis identifying species of interest corresponding to BCO-DMO dataset 991182 (doi: 10.26008/1912/bco-dmo.991182.1)

The workflow release (v1.0.0) contains data and scripts used to run analyses and produce figures for publication Leavitt, H; Thomas, A; Doerr, J; Johnson, D; Nelson, J. (In press) Resilient Nekton Composition in the Face of Climate-Driven Foundation Species Shifts. Ecology. Accepted 2025-11-14
