“…PCA based on genotypic relationship were frequently used in several studies to give a valuable insight to better understanding of population structure and genetic relations between individuals (Sabeti et al, 2007). We observed dense structure in domestic goat population in comparison to wild individuals; it might be due to high degree of selection pressure for economic traits in domestic goats (Taheri et al, 2022). It is necessary to point out that small sample size in the current may not reveal the actual diversity.…”

“…In this study, samples were collected from unrelated individuals, which were including 20 Iranian domestic goats ( C. hircus) and 18 Iranian wild goats ( C. aegagrus ). These samples were collected from north western of Iran, as it was described by Taheri et al (2022). Samples were collected randomly and from distal part of ear and 25 mg of tissue was subjected to DNA extraction by the Macherey Nagel NucleoSpin 96 Tissue kit, following manufacturer's instruction (Alberto et al, 2018).…”

Identification of selection signatures may provide a better understanding of domestication process and candidate genes contributing to this process. In this study, two populations of domestic and wild goats from Iran were analyzed to identify selection signatures. RSB, iHS, and XP‐EHH statistics were used in order to identify robust selection signatures in the goat genome. Genotype data of domestic and wild goats from the NextGen project was used. The data was related to 18 Capra aegagrus (wild goat) and 20 Capra hircus (domestic goat) from Iran. The iHS method indicated 675 and 441 selection signatures in C. aegagrus and C. hircus, respectively. RSB and XP‐EHH methods showed about 370 and 447 selection signatures in C. aegagrus and C. hircus, respectively. These selection signatures were mainly associated with milk production, fleece trait, mammary epithelial cells, reproduction, and immune system.

“…Previous studies have employed models to discover why small and isolated populations have an increased risk of extinction due to the interplay between genetics and demography 9 . Assessing the allelic richness of species and populations is widely employed to quantify genetic diversity, thereby evaluating fitness and adaptability in response to environmental changes 10 – 12 .…”

The genetic status and rescue measure for a geographically isolated population of Amur tigers

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.
