DNA barcoding revises a misidentification on musk deer

Area of Science:

• Wildlife conservation
• Molecular genetics
• Taxonomy

Background:

• Musk deer (genus Moschus) are endangered in China, necessitating clear taxonomic status and distribution for effective conservation.
• Uncertainty exists regarding the species identification of musk deer in Shanxi Province, potentially extending ranges of Forest Musk Deer or Siberian Musk Deer.

Purpose of the Study:

• To clarify the species status of musk deer in Shanxi Province using molecular methods.
• To determine the precise distribution of musk deer species in China.

Main Methods:

• DNA barcoding was employed, sequencing the COI and D-loop genes from 12 musk deer samples from Guandi Forest District, Shanxi, and two reference samples from Sichuan.
• Genetic analysis of mitochondrial DNA (COI and D-loop genes) was performed.

Main Results:

• Genetic data indicate that all sampled musk deer from Guandi Forest District belong to the Forest Musk Deer (M. berezovskii), not the Siberian Musk Deer (M. moschiferus).
• This study provides the first DNA evidence confirming Shanxi Province as a new distribution area for M. berezovskii.
• Previous species identifications in the region may have been inaccurate.

Conclusions:

• The musk deer population in Shanxi Province is identified as M. berezovskii, expanding its known geographical range.
• DNA barcoding is a valuable tool for resolving taxonomic uncertainties and identifying species distribution in wildlife conservation efforts.
• Accurate species identification is crucial for developing targeted conservation strategies for endangered musk deer.
