Insights into the genetic diversity of the leopard seal (Hydrurga leptonyx), inferred
from mitochondrial DNA analysis, at Danco Coast, Antarctic Peninsula
The leopard seal (Hydrurga leptonyx) is a genetically low-studied species. In order to conduct the first genetic diversity assessment of this species in Danco Coast (Antarctic Peninsula), 423 bp of the mitochondrial DNA Control Region (mtDNA-CR) was sequenced
from 13 blood samples collected in Primavera Base (62º15’S, 58º39’W) during the 2011-2012 austral summer. Our results showed high haplotype diversity (h = 0.99), with various divergent haplotypes. Our findings suggest that leopard seals in the Danco Coast could
represent different phylogroups; however, including more genetic markers are needed to confirm this hypothesis.
