Article Synopsis
- The growing demand for eco-friendly and diverse pig feeding systems highlights the importance of rearing and conserving local pig breeds, like the Livni pig, which is well-adapted to Russia's environment.
- A study analyzed the genetic diversity of Livni pigs using SNP data from different populations and compared it to commercial breeds like Landrace and Large White.
- Results showed that Livni pigs have higher genetic diversity, lower inbreeding, and a unique population structure, indicating less selection pressure compared to mainstream commercial breeds.
Poaching is one of the major types of wildlife crime in Russia. Remnants of goats (presumably the wild endemic species, the Caucasian tur) were found in an area of the Caucasian mountains. The case study involves a suspected poacher whose vehicle was found to have two duffel bags containing pieces of a carcass, which he claimed was that of a goat from his flock.

In our previous work using whole-genome single nucleotide polymorphism (SNP) analysis, we found that the population inhabiting Kharaulakh Ridge was genetically different from the other populations of Yakut subspecies to which it was usually referred. Here, our study was aimed at the clarification of taxonomic status of Kharaulakh snow sheep using mitochondrial cytochrome b gene.

Article Synopsis
- This study examined the genetic characteristics and selection signatures of two Russian native cattle breeds, Yaroslavl and Kholmogor, using high-density SNP genotyping and a variety of statistical analyses.
- Researchers identified nine selection regions in Yaroslavl and six in Kholmogor, with some overlap with Holstein cattle but also discovered three unique selection sweeps in each breed.
- The findings also included a list of candidate genes linked to these genomic regions, and the potential role of these genes in artificial selection related to the breeds' genetic evolution.
Article Synopsis
- The study analyzes ancient and historical DNA to trace genetic diversity in five Russian cattle breeds over time, using samples from the late 19th to early 20th century.
- It identifies genotyping errors, such as allelic drop-out and false alleles, at low frequencies and shows that allelic length affects the rate of allelic drop-out.
- Overall, the research indicates that modern Kholmogor and Yaroslavl breeds retain significant historical genetic components, contributing to the conservation of Russia's cattle biodiversity.
To examine the genetic diversity and population structure of domestic reindeer, using the BovineHD BeadChip, we genotyped reindeer individuals belonging to the Nenets breed of the five main breeding regions, the Even breed of the Republic of Sakha, the Evenk breed of the Krasnoyarsk and Yakutia regions, and the Chukotka breed of the Chukotka region and its within-breed ecotype, namely, the Chukotka-Khargin, which is bred in Yakutia. The Chukotka reindeer was shown to have the lowest genetic diversity in terms of the allelic richness and heterozygosity indicators. The principal component analysis (PCA) results are consistent with the neighbor-net tree topology, dividing the reindeer into groups according to their habitat location and origin of the breed.

Reindeer (Rangifer tarandus L. 1758) are an essential element of the Russian Far North, providing a significant source of nutrition for the representatives of 18 ethnicities. The species has wild and domestic forms, which are in constant interaction.

- * A small percentage of these SNPs were polymorphic, indicating low genetic variation, with 5.3% for bovines and 2.03% for ovines.
- * Despite varying distributions of SNPs across chromosomes, the results suggest that bovine and ovine SNP chips are effective tools for conducting whole-genome analysis in reindeer.
