Mitochondrial genome of captive Alpine musk deer, Moschus chrysogaster (Moschidae), and phylogenetic analyses with its coordinal species.

ABSTRACT: Alpine musk deer, Moschus chrysogaster, a solitary, primitive ungulate inhabiting high elevation areas (3000-4500 m) is an endangered species facing threat of extinction globally due to excessive hunting for its musk. In this study, we determined the complete mitochondrial genome of M. chrysogaster, which was 16,354 bp in length, and revealed the same gene order and genomic organization as typical Moschidae mitochondrial DNA. Start codons in 13 protein-coding genes (PCGs) were all typical ATGs except ATA for ND2 and ND3 and ATT for ND5. Stop codons were all typical types except an incomplete stop codon T for COX3, ND2, ND3, and ND4. Secondary structures in 22 transfer RNA genes all showed typical cloverleaf except tRNA-Ser (AGY), in which the dihydrouridine arm formed a simple loop. No repeat units were found in the control region. The topology structure indicated that M. cupreus was primitive and located at the root of the Moschidae clade. Phylogenetic reconstruction placed M. chrysogaster as a distinct lineage, closely related to the branch of M. leucogaster, M. berezovskii (wild) and predicted a sister relationship with M. moschiferus, M. anhuiensis, and M. berezovskii (captive). However, we suggested that the genetic resources of M. chrysogaster_JQ608470 should be further investigated.

Project description:Comprehension of whether human and livestock presence affects wildlife activity is a prerequisite for the planning and management of humans and livestock in protected areas. Xinglong Mountain Nature Reserve (XMNNR) in northwest China, as a green island in a semi-arid mountain ecosystem, is one of the scattered and isolated areas for Alpine musk deer (AMD), an endangered species. AMD cohabits their latent habitat area with foraging livestock and humans. Hence, habitat management within and outside the distribution areas is crucial for the effective conservation of AMD. We applied camera traps to a dataset of 2 years (September 2018-August 2020) to explore seasonal activity patterns and habitat use and assess the impacts of AMD habits in XMNNR. We investigated AMD responses to livestock grazing and human activities and provided effective strategies for AMD conservation. We applied MaxENT modeling to predict the distribution size under current conditions. The activity patterns of the AMD vary among seasons. The optimum habitat average distance to cultivated land ranges of AMD (150~3300 m during grass period/100~3200 m during withered grass period), distances to the residential area ranges (500~5700 m during the grass period/1000~5300 m during the withered grass period), elevation ranges (2350~3400 m during the grass period/2360~3170 m during the withered grass period), aspect ranges (0~50° and 270~360°), normalized vegetation index ranges (0.64~0.72 during the grass period/0.14~0.60 during the withered grass period), and land cover types (forest, shrub, and grassland). Results present that the predicted distributions of AMD were not confined to the areas reported but also covered other potential areas. The results provide evidence of strong spatial-temporal avoidance of AMD in livestock, but gradually adjusting to human activities. These camera trap datasets may open new opportunities for species conservation in much wider tracts, such as human-dominated landscapes, and may offer guidance and mitigate impacts from livestock, as well as increase artificial forest planting and strengthen the investigation of the potential population resources of AMD.
