Using DNA Barcoding to Assess Caribbean Reef Fish Biodiversity: Expanding Taxonomic and Geographic Coverage

<div><p>This paper represents a DNA barcode data release for 3,400 specimens representing 521 species of fishes from 6 areas across the Caribbean and western central Atlantic regions (FAO Region 31). Merged with our prior published data, the combined efforts result in 3,964 specimens representing 572 species of marine fishes and constitute one of the most comprehensive DNA barcoding “coverages” for a region reported to date. The barcode data are providing new insights into Caribbean shorefish diversity, allowing for more and more accurate DNA-based identifications of larvae, juveniles, and unknown specimens. Examples are given correcting previous work that was erroneous due to database incompleteness.</p> </div

Dendrogram including three instances of specimen and taxonomic confusion discussed in the text.

<p>Combined barcoding data from Mexico (MFL- and MX- prefixes) <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0041059#pone.0041059-ValdezMoreno1" target="_blank">[24]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0041059#pone.0041059-ValdezMoreno2" target="_blank">[25]</a> with our data (BLZ = Belize; CUR = Curacao; FCC = Florida; FL = Florida; SMS = Florida) and shown in a dendrogram for visualization purposes only, with no intent to show phylogenetic relationships. The triangles are to scale showing the maximum amount of genetic variation within the clade, which ranges from the straight line (no differences between individuals) of the bottom clade (<i>Bairdiella chrysoura</i>) to the largest intraspecific variation in the <i>Eucinostomus gula</i> clade (B-white triangle: largest pairwise genetic distance = 0.0894) Interspecific and inter-clade distances and significance is discussed in the text.</p
