“…Meadows et al [15], on the other hand, were the first to identify a fifth lineage (E) in the Tuj and Ivesi sheep breeds in a sample population consisting of Israeli Ivesi sheep and the Karakaş, Norduz, Morkaraman, Tuj, Çine Çaparı, Sakız, Karya, and Karayaka sheep breeds. In the Şavak breed that we investigated in this study, the D and E haplogroups were not found, but the A, B, and C haplogroups were identified, which are consistent with other similar studies [3,13,15,30,31]. The nucleotide diversity values identified in the Şavak Akkaraman breed were similar to those found by Pedrosa et al [13], but were lower than the 3 different domestic Chinese sheep breeds [32] and 13 domestic sheep breeds [3].…”

While the haplotype diversity found in the Şavak Akkaraman sheep is similar to that found by Zhao et al [32] in 3 different domestic Chinese sheep breeds, by Demirci et al [3] in 13 domestic Turkish sheep breeds, by Liu et al [33] and Guangxin et al [31] in Tibetan sheep, by Kuseniuk and Slota, [34] in Poland sheep, by Alonso et al [35] in Mexican Creole sheep, and by Nigussie et al [36] in Ethiopia sheep, the study that Chen et al [37] conducted in domestic Chinese sheep is lower than the Şavak Akkaraman breed. In other words, the haplotype diversity in the Şavak Akkaraman breed is higher.…”

“…In the study conducted by Pedrosa et al [13], haplogroup A was only predominant in the Morkaraman breed. Guangxin et al [31] reported that haplogroup A is dominant in Tibetan sheep. However, Pedrosa et al [13] reported that haplogroup B is generally dominant.…”

This study was conducted to investigate the maternal genetic diversity using the mtDNA D -loop region 842 base pair (bp) polymorphism in Şavak Akkaraman sheep raised in the province of Erzincan. According to the results, in the mtDNA D -loop of the Şavak Akkaraman breed, 27 polymorphic sites and 20 haplotypes were identified and then, 11 of the 20 haplotypes identified in Şavak sheep were in haplogroup B (55%), 6 in haplogroup A (30%), and 3 in haplogroup C (15%). Haplogroup B was the most frequent haplogroup in Şavak Akkaraman sheep. Haplotype and nucleotide diversities were estimated to be 0.995 ± 0.004 and 0.0146 ± 0.0003, respectively. The Şavak Akkaraman breed was compared with the mtDNA sequencing of different breeds and wild sheep, and the contribution of the breed to biodiversity was considered.

“…Generally, indigenous domestic animals in Tibet are thought to have been introduced with the migration of Tibetan ancestors from northern China approximately 7,000 years ago [ 2 , 3 ]. Research based on mitochondrial DNA (mtDNA) revealed that Tibetan mastiff [ 4 ], Tibetan sheep [ 5 ] and Tibetan chicken [ 6 ] were derived from outside of Tibet, and Tibetan yak [ 7 ] and Tibetan pig [ 8 ] were appear to have a local origin. However, we currently have no direct genetic evidence regarding whether Tibetan horses originated in the region or were descended from exotic breeds.…”

Haplotype diversity in mitochondrial DNA reveals the multiple origins of Tibetan horse

et al. 2018

The Tibetan horse is a species endemic to the Tibetan plateau, with considerable economic value in the region. However, we currently have little genetic evidence to verify whether the breed originated in Tibet or if it entered the area via an ancient migratory route. In the present study, we analyzed the hypervariable segment I sequences of mitochondrial DNA (mtDNA) in 2,050 horses, including 290 individuals from five Tibetan populations and 1,760 from other areas across Asia. Network analysis revealed multiple maternal lineages in the Tibetan horse. Component analysis of sub-lineage F3 indicated that it decreased in frequency from east to west, a trend reflected both southward and northward from Inner Mongolia. Analysis of population genetics showed that the Deqen horse of eastern Tibet was more closely related to the Ningqiang horse of northern China than to other Tibetan horses or the Yunnan horse. These results indicated that the Tibetan horse migrated first from Central Asia to Mongolia, moved south to eastern Tibet (near Deqen), then finally westward to other regions of Tibet. We also identified a novel lineage K that mainly comprises Tibetan and Yunnan horses, suggesting autochthonous domesticated origin for some Tibetan horse breeds from local wild horses. In conclusion, our study demonstrated that modern Tibetan horse breeds originated from the introgression of local wild horses with exotic domesticated populations outside China.

“…Mitochondrial DNA sequence analysis led to the identification of five maternal haplotypes (A-E) that are currently recognised in various sheep populations around the world (Meadows et al, 2011). Tibetan sheep are believed to have descended from a combination of Ovis vignei, Ovis ammon (both of unknown haplotype) and animals of haplotypes A, B, and C (Guangxin et al, 2017).…”

Yaks and sheep trigger different changes in the grasshopper assemblages of the Qilian Mountains via differentially altering plant assemblages

1. The Qilian Mountains represent one of the key livestock‐raising grasslands in China. The two main herbivore species raised in this area – yaks and sheep – are of critical economical value. Grasshoppers compete with these animals for available nutrients, creating multifaceted relationships between livestock, grasshoppers and plants. A clear understanding of such relationships is lacking and is urgently needed to guide conservation efforts. 2. This study aims to document the effects of yak and sheep grazing on grasshopper assemblages and to elucidate the underlying mechanisms of such effects. 3. It is shown here that yaks and sheep impact grasshopper assemblages differently. Grasshopper assemblages exhibited lower density, biodiversity, richness, and evenness of distribution in yak‐grazed pastures than in grazing‐free grasslands. Sheep‐grazed pastures exhibited a dramatically divergent picture, with elevated density, biodiversity and richness, and a slightly decreased evenness of distribution. Grasshoppers were generally larger in grazed pastures than in grazing‐free grasslands, especially in yak‐grazed plots. 4. The present study suggests that differences between yak and sheep pastures in plant assemblage structure and plant traits are probably the underlying forces driving the differences in grasshopper assemblage structure and grasshopper traits, respectively. 5. The study shows that the grasshopper habitat indicator species differ between yak and sheep pastures, raising the possibility that such indicators can be used to monitor grassland usage and degradation in the Qilian Mountains. 6. These results provide novel insights into the dynamic interactions of common domesticated herbivore species, grasshoppers and plants in Qilian Mountains, which augment current knowledge and may ultimately lead to better conservation practices.
