Summary: This study investigated the genetic diversity and population structure of local Sudanese sheep populations, revealing three genetic groups based on tail morphotype, geographical distribution, and population subtype. The thin-tailed Sudanese sheep populations showed distinct clustering from the fat-tailed Ethiopian and Libyan sheep, with clear signatures of admixture observed among the local Sudanese sheep populations.

Summary: The genetic diversity and population structure of the Yufen 1 H line (YF) were investigated and compared with other poultry breeds. The results showed that YF had low genetic diversity and a slower rate of linkage disequilibrium decay compared to other Chinese indigenous breeds. Furthermore, it was found that the YF population has been threatened and calls for the establishment of conservation strategies and utilization techniques to maintain genetic diversity.

Summary: Genetic diversity of local chicken populations in Sri Lanka was analyzed using microsatellite markers, revealing high diversity and potential for crossbreeding between different phenotypes. This diversity is attributed to differences in breeding practices and interactions between villages, indicating a rich gene pool that could be utilized for future breeding programs.

Summary: This study investigates the effects of anthropogenic disturbances on the genetic variability of tree species using Ailanthus altissima as a case study. The results suggest that although genetic variation does not differ substantially between disturbed and undisturbed sites, disturbed forests may exhibit higher genetic diversity and population bottlenecks.

Summary: As global warming becomes more complex and difficult to manage, the conservation and sustainable use of locally adapted sheep breeds are becoming important. This study sequenced the genomes of Portuguese native sheep breeds to analyze their genomic diversity and population structure. The results provide insights into the potential of genomic data for guiding conservation efforts and identifying breed markers.

Summary: Genetic diversity analysis is crucial for maintaining and managing genetic resources. This study analyzed the genetic diversity of Korean domestic chicken populations using high-density SNP genotype data. The results showed that indigenous Korean native chicken populations were genetically closer and more fixed, while adapted Korean native chicken and commercial chicken populations had different genetic structures.

Summary: Biological invasions are a significant component of global change, but they can also have negative impacts on native populations. Efficient management policies are needed to prevent the spread of invasive species in non-native areas while protecting native populations. Genetic variation analysis can help assess the genetic state, identify invasion pathways, determine management strategies, and identify populations requiring conservation measures.

Summary: The genetic diversity, relationships, and population structures of Guizhou indigenous chicken breeds were analyzed in this study. The results showed higher genetic diversity in Guizhou chicken breeds compared to commercial chicken breeds. The population structure analysis reflected the breeding history and geographical distribution of Guizhou indigenous chickens. Selective sweep analysis revealed candidate genes associated with specific phenotypic characteristics and economic traits. The study provides important genetic information for further research, conservation, and breeding of Guizhou indigenous chickens.

Summary: This study systematically evaluated the population structure and demography of current Tibetan chicken populations, revealing complex genetic histories and a clear separation into 4 sub-populations. Two high altitude associated genes were found in all 4 sub-populations, indicating similar responses to selection pressures. These results have important implications for future genetic analyses on chickens and other domestic animals in Tibet.

Summary: The study analyzed the mtDNA D-loop sequences of 1163 Chinese indigenous cattle to determine their maternal origin and population genetic structure, prioritizing conservation evaluations based on a population genetic model. Three maternal origins or domestication events were identified among Chinese indigenous cattle, with various levels of genetic diversity and contributions to the richness of genetic resources. The research provides a scientific basis and effective evaluation methods for the protection of genetic resources of indigenous livestock varieties.

Summary: The study revealed high genetic diversity in E. japonica, with variation mainly within populations. Both deciduous and evergreen populations of E. japonica were identified, showing significant genetic differentiation between them but little differentiation among geographic populations. Conservation efforts should focus on in-situ protection, seed collection, and vegetative propagation to maintain the distinct genetic characteristics of different populations.
