“…Some species have also benefited from translocation and reintroduction programmes (e.g. Pekania pennanti , Martes zibellina and Martes martes ; Lewis et al 2012, Monakhov et al 2018, McNicol et al 2020). While the extent of the threat from trapping has almost certainly reduced over the last few decades, many of these species are still susceptible to overharvesting, because of their relatively low reproductive rates (Helldin 2000).…”

The family Mustelidae is the largest among the order Carnivora. While we know a great deal about certain species, there is still a lack of information about many mustelids. We first investigated the International Union for Conservation of Nature (IUCN) Red List species‐level assessments for each mustelid species. Then, we undertook a systematic review of the scientific literature with the aim of identifying the primary threats and subthreats reported, and which species are most studied. Threats are defined by the IUCN as “the proximate human activities or processes that have impacted, are impacting, or may impact the status of the taxon”. We analysed 1003 published articles. For each article, we collected year of publication, geographical zone of each study, species studied, and the threats and subthreats identified. The majority of species (62%) were classified as Least Concern on the IUCN Red List, but 31 out of 63 species were found to be declining globally and only two species were increasing. The species studied and location of studies were biased, with 72% of studies undertaken in North America or Europe and focussing on very few species. A high proportion of species distributed predominantly in the tropics were categorised as declining, and threats linked with hunting, fishing, and logging were identified as the most common for mustelids by the IUCN Red List and in the scientific literature. Differences in the proportion of threats affecting each subfamily were also reported. The nature of threats varies in different parts of the world and between species. It is essential to undertake more research with a strong focus towards species in highly biodiverse regions. A greater understanding of threats such as wildlife pet trade, emerging diseases, and climate change must also be central to prevent declines.

“…The sable ( Martes zibellina ), a carnivorous mammal distributed across the cold northern zone of Eurasia (Li et al 2013 ), is famous for its valuable, warm fur (Guan et al 2016 ; Monakhov et al 2018 ; Svishcheva and Kashtanov 2011 ). The sable has a slender body and a high surface-to-volume ratio, and it maintains a low body fat percentage of approximately 8%, even during particularly cold winters (Mustonen and Nieminen 2006 ).…”

Sable (Martes zibellina), a member of family Mustelidae, order Carnivora, is primarily distributed in the cold northern zone of Eurasia. The purpose of this study was to explore the intestinal flora of the sable by metagenomic library-based techniques. Libraries were sequenced on an Illumina HiSeq 4000 instrument. The effective sequencing data of each sample was above 6000 M, and the ratio of clean reads to raw reads was over 98%. The total ORF length was approximately 603,031, equivalent to 347.36 Mbp. We investigated gene functions with the KEGG database and identified 7140 KEGG ortholog (KO) groups comprising 129,788 genes across all of the samples. We selected a subset of genes with the highest abundances to construct cluster heat maps. From the results of the KEGG metabolic pathway annotations, we acquired information on gene functions, as represented by the categories of metabolism, environmental information processing, genetic information processing, cellular processes and organismal systems. We then investigated gene function with the CAZy database and identified functional carbohydrate hydrolases corresponding to genes in the intestinal microorganisms of sable. This finding is consistent with the fact that the sable is adapted to cold environments and requires a large amount of energy to maintain its metabolic activity. We also investigated gene functions with the eggNOG database; the main functions of genes included gene duplication, recombination and repair, transport and metabolism of amino acids, and transport and metabolism of carbohydrates. In this study, we attempted to identify the complex structure of the microbial population of sable based on metagenomic sequencing methods, which use whole metagenomic data, and to map the obtained sequences to known genes or pathways in existing databases, such as CAZy, KEGG, and eggNOG. We then explored the genetic composition and functional diversity of the microbial community based on the mapped functional categories.

Sable has a slender body and a high surface-tovolume ratio which maintain a low body fat rate of about 8 percent even during particularly cold winters , thus a high energy metabolic rate should be required for survival ), so we decided to investigate the correlations of metabolism function with intestinal ora.…”

Sable (Martes zibellina), belongs to Carnivora, Mustelidae and Maretes, was mainly distributed among the cold northern zone of Eurasia. The purpose of this study is to explore the intestinal flora of the sable by the method of the metagenomic library-based technique, libraries were sequenced on an Illumina HiSeq 4000 instrument. Effective Data volume of each sample is above 6000M, the ratio of the Effective Data (the Clean Data) to original Data (Raw Data) is over 98%. According to the analysis of statistical data, the Total length of ORF is about 603,031, which is 347.36 Mbp. We contrast the unique function of genes with KEGG database, we acquire 7140 genes (KO), a total of all the samples KO is 129788. We selected higher abundance genes to draw cluster heat maps, and according to the results of the KEGG metabolic pathway annotations, we acquire the gene function，including metabolism, environmental information processing, genetic information processing, cellular process and organismal systems. We contrast the unique function of genes with CAZy database, the functional carbohydrate hydrolases have corresponding genes in the intestinal microorganisms of the sable. This is closely related to the fact that the sable is adapted to cold environments and requires a large amount of energy to maintain its metabolic activity. We contrast the unique function of genes with eggNOG database，the main functions of genes included gene duplication, recombination and repair, transport and metabolism of amino acids, transport and metabolism of carbohydrates, etc. In this study, we intended to identify the complex microbial population structure of sables based on metagenomic sequencing method, which uses the whole metagenomic data, mapping the sequences to the known genes or the pathways in the existing databases, such as CAZy, KEGG, or eggNOG, and then exploring the genetic composition and functional diversity of microbial community based on the mapped functional categories.
