Data from: Biodiversity and biogeographic affinity of benthic amphipods from the Yucatan Shelf: an analysis across the warm Northwest Atlantic ecoregions

The resource provides a list of 491 species representing the biodiversity of benthic amphipods from 12 ecoregions in the Northwest Atlantic. The dataset contains an Excel sheet with species occurrence data from benthic marine habitats of the continental shelf (< 200 m), forming a comprehensive collection of distributional data (presence-only) that was obtained from different sources and newly-sampled material in the Yucatan continental shelf, and sorted according to the ecoregions. This information form part of a published article in the journal Systematics and Biodiversity (Paz-Ríos et al. 2021). To link to this article: https://doi.org/10.1080/14772000.2021.1947920

Eleven ecoregions defined by Spalding et al. (2007) were used for sorting species occurrence data; an additional ecoregion defined by Wilkinson et al. (2009) was also used to represent the species occurrence data in the Yucatan continental shelf. Ecoregion names: (BAH) Bahamian; (BER) Bermuda; (CAR) Carolinian; (ECA) Eastern Caribbean; (FLO) Floridian; (GRA) Greater Antilles; (NGM) Northern Gulf of Mexico; (SCA) Southern Caribbean; (SWCA) Southwestern Caribbean; (SGM) Southern Gulf of Mexico; (WCA) Western Caribbean; and (YUC) Yucatan.
