摘要

豹纹海豹（Hydrurga leptonyx）是一种基因研究较少的物种。为了在丹科海岸（南极半岛）对该物种进行首次遗传多样性评估，从2011-2012年南半球夏季采集的Primavera基地（62º15'S，58º39'W）的13份血液样本中测序了423bp的线粒体DNA控制区（mtDNA CR）。我们的结果显示出高度的单倍型多样性（h=0.99），具有各种不同的单倍类型。我们的研究结果表明，丹科海岸的豹海豹可能代表不同的门群；然而，需要包括更多的遗传标记来证实这一假设。

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.
