A Study of Pencil Urchin Population Genetics at Hannibal Bank

A Study of Pencil Urchin Population Genetics at Hannibal Bank
Research paper
Description: 

Hannibal Bank is a seamount-like feature known for its high productivity and biodiversity that is located in an UNESCO World Heritage Site off the Pacific coast of Panama. The biodiversity and biogeography of two species of pencil urchins at Hannibal Bank were studied using genetic analysis and geographical imaging systems. DNA barcoding of the COI mitochondrial gene identified gene sequences for 80 samples of two species of pencil urchins (Genus Hesperocidaris). Analyses of the geography and bathymetry of the bank indicated that both pencil urchin species demonstrated high gene flow and no significant genetic population structure. Samples of species 1 were distributed primarily on the northern and southern flanks of the bank with some near the peaks with recent population expansion indicated by haplotypes. Samples of species 2 were distributed intermittently along the flank of the bank’s perimeter and the haplotype network indicated that it is an evolutionary stable population.
