Abstract: | Background Science-based wildlife management relies on genetic information to infer population connectivity and identify conservation
units. The most commonly used genetic marker for characterizing animal biodiversity and identifying maternal lineages is the
mitochondrial genome. Mitochondrial genotyping figures prominently in conservation and management plans, with much of the
attention focused on the non-coding displacement ("D") loop. We used massively parallel multiplexed sequencing to sequence
complete mitochondrial genomes from 40 fishers, a threatened carnivore that possesses low mitogenomic diversity. This allowed
us to test a key assumption of conservation genetics, specifically, that the D-loop accurately reflects genealogical relationships
and variation of the larger mitochondrial genome. |
