“…Genetic diversity, one of the three aspects of biodiversity (including genetic diversity, species diversity, and ecosystem diversity), is regarded as a parameter that effectively reflects the variability of the demographic and historical population processes 13 , 14 . Defining the amount and distribution of genetic variation within and among populations by using genetic structure is a crucial research direction in the fields of genetics and bioinformatics 15 , 16 . The effective population size, a core evolutionary parameter, exerts an influence on the rate of genetic diversity loss as large populations could store greater genetic variation while governing the mating selection space, affecting the probability of inbreeding within populations 17 – 19 .…”

The Amur tiger is currently confronted with challenges of anthropogenic development, leading to its population becoming fragmented into two geographically isolated groups: smaller and larger ones. Small and isolated populations frequently face a greater extinction risk, yet the small tiger population’s genetic status and survival potential have not been assessed. Here, a total of 210 samples of suspected Amur tiger feces were collected from this small population, and the genetic background and population survival potentials were assessed by using 14 microsatellite loci. Our results demonstrated that the mean number of alleles in all loci was 3.7 and expected heterozygosity was 0.6, indicating a comparatively lower level of population genetic diversity compared to previously reported studies on other subspecies. The genetic estimates of effective population size (Ne) and the Ne/N ratio were merely 7.6 and 0.152, respectively, representing lower values in comparison to the Amur tiger population in Sikhote-Alin (the larger group). However, multiple methods have indicated the possibility of genetic divergence within our isolated population under study. Meanwhile, the maximum kinship recorded was 0.441, and the mean inbreeding coefficient stood at 0.0868, both of which are higher than those observed in other endangered species, such as the African lion and the grey wolf. Additionally, we have identified a significant risk of future extinction if the lethal equivalents were to reach 6.26, which is higher than that of other large carnivores. Further, our simulation results indicated that an increase in the number of breeding females would enhance the prospects of this population. In summary, our findings provide a critical theoretical basis for further bailout strategies concerning Amur tigers.

“…The resulting architecture of genotypes provides a promising solution to secure future crop stability [5,6]. Numerous wild and cultivated barley accessions have been collected and conserved in gene banks [7][8][9], which await geographic, phenotypic, and molecular characterisation. Collections of landraces are therefore an important source of germplasm, genes, and traits to improve the sustainability of agriculture in the face of climate change and other environmental perturbations [10][11][12], while also having value in the assessment of the impacts of climate, migration, and trade in agrarian history [13,14].…”

“…Liu et al analyzed the genetic diversity of 1481 individuals using SSR markers and SNP haplotypes [21]. In addition, SSR also plays an essential role in the study of the genetic diversity of cowpea [22], barley [23], beans [24,25], maize [26], and other crops. Therefore, it is feasible to screen specific SSR primers for genetic diversity analysis of Shanlan upland rice to explore its geographical origin.…”

Shanlan upland rice (Oryza sativa L.) is a unique upland rice variety cultivated by the Li nationality for a long time, which has good drought resistance and high utilization value in drought resistance breeding. To explore the origin of Shanlan upland rice and its genetic relationship with upland rice from other geographical sources, 214 upland rice cultivars from Southeast Asia and five provinces (regions) in southern China were used to study genetic diversity by using SSR markers. Twelve SSR primers were screened and 164 alleles (Na) were detected, with the minimum number of alleles being 8 and the maximum number of alleles being 23, with an average of 13.667. The analysis of genetic diversity and analysis of molecular variance (AMOVA) showed that the differences among the materials mainly came from the individuals of upland rice. The results of gene flow and genetic differentiation revealed the relationship between the upland rice populations, and Hainan Shanlan upland rice presumably originated from upland rice in Guangdong province, and some of them were genetically differentiated from Hunan upland rice. It can be indirectly proved that the Li nationality in Hainan is a descendant of the ancient Baiyue ethnic group, which provides circumstantial evidence for the migration history of the Li nationality in Hainan, and also provides basic data for the advanced protection of Shanlan upland rice, and the innovative utilization of germplasm resources.
