Abstract:

A phylogenetic analysis of concatenated plastid (psbA) and nuclear (LSU rDNA) DNA sequences of non-geniculate corallines belonging to the subfamily Lithophylloideae (Corallinaceae), including newly generated sequences from recently collected specimens dredged at Ewing and Sackett Banks following the April 2010 Deepwater Horizon oil spill, reveals at least two distinct species of Lithophyllum sensu lato for the region.

Richards, J. L., Gabrielson, P. W., & Fredericq, S. (2014). <strong>New Insights into the Genus <em>Lithophyllum</em> (Lithophylloideae, Corallinaceae, Corallinales) from Deepwater Rhodolith Beds Offshore the NW Gulf of Mexico</strong>. Phytotaxa, 190(1), 162. doi:10.11646/phytotaxa.190.1.11

Purpose:

The biological dataset produced is part of a long-term study of offshore NW Gulf of Mexico seaweeds. The goal is to correctly identify and assess the function of rhodoliths (red algal nodules) and seaweeds for biological diversity in offshore hard banks in the NW Gulf of Mexico, and their decline/shift post-DWH.

Data Parameters and Units:

Descriptors for each DNA sequence, including: Locus, total number of base pairs, Definition, Accession number, Accession Version number, Keywords, Source, Organism, References, Comments, Features (source, gene, CDs, rRNA), Origin (DNA sequence)

Methods:

Retrieval of rhodoliths and corallines with box dredging, use of CTD for multi-parameter environmental data and rosette with Niskin bottles for retrieval of seawater in situ/depth of algal collections

Instruments:

Box dredges, CTD, light microscopy, Scanning electron microscopy, ABI PCR machines and automated DNA sequencers

Provenance and Historical References:

Post-DWH vouchers were assessed against pre-and post-DWH historical data, e.g. -Fredericq S., Cho, T. O., Earle, S. A., Gurgel, C. F., Krayesky, D. M., Mateo-Cid, L. E., Mendoza Gonzáles, A.
