Summary: This study assessed the genetic diversity of the ridgetail white prawn Exopalaemon carinicauda in China and found moderate to high levels of genetic diversity among different populations. The analysis also revealed low genetic differentiation among the populations and identified three distinct clusters based on phylogenetic and STRUCTURE analysis.

Summary: This study revealed a significant genetic differentiation among populations of Collichthys lucidus, with temperature-related genes playing a critical role in the species' adaptation to spatially heterogeneous temperatures. These findings shed light on how C. lucidus populations may respond to future ocean temperature rising.

Summary: The genetic diversity of potato breeding germplasm in the Nordic region was found to be low, and there is a close relationship between the breeding material and the germplasm from the genebank. Genotypes from outside the Nordic region should be employed for genetic hybridization.

Summary: Null alleles are recessive alleles that do not affect the phenotype of codominant markers. In microsatellite studies, null alleles are mainly used for pedigree analysis and population genetics calculations. However, the presence of null alleles can lead to biased results and it is important to consider possible solutions.

Summary: Understanding the genetic structure and diversity of insect vectors is crucial for disease epidemiology. This study used mitochondrial cytochrome c oxidase I sequences to infer the genetic diversity, structure, and population history of the black fly Simulium chumpornense Takaoka and Kuvangkadilok, a suspected vector of blood protozoa. The results showed high intraspecific genetic divergence and revealed two genetic lineages that were geographically associated. The population pairwise F-ST analysis indicated significant genetic differences among almost all population comparisons, suggesting a high level of genetic structuring possibly due to historical isolation during glaciations.

Summary: Understanding population connectivity and genetic diversity is crucial for conservation, but it remains challenging for globally threatened marine megafauna. This study uses a comparative framework to investigate the genetic differentiation and diversity of manta rays, revealing higher connectivity and heterozygosity in oceanic manta rays. The findings also emphasize the potential impact of fisheries on population dynamics.

Summary: This study assessed the genetic diversity and population structure of 196 Saccharum accessions, including various species and hybrids, using multiple analysis methods. The results showed that different species of sugarcane merged together, and specific alleles were important for sugarcane breeding and species identification. These findings provide valuable information for future genetic research and utilization of sugarcane germplasm resources.

Summary: Using microsatellite markers, this study evaluated the genetic diversity and population structure of Konosirus punctatus in the Northwestern Pacific Ocean, revealing five genetically divergent clades and significant isolation by distance. The results suggest that historical climate shifts and environmental factors may contribute to the present-day genetic architecture of K. punctatus, providing new perspectives for effective management strategies.

Summary: The distribution range of rice root-knot nematode Meloidogyne graminicola is expanding rapidly in China, posing a serious threat to rice production. The genetic analysis of M. graminicola populations from different provinces in China revealed distinct geographical distribution characteristics in three clusters. The high haplotype diversity and low nucleotide diversity suggested the expansion of nematode populations, while the high genetic differentiation indicated limited gene flow between populations.

Summary: In this study, the genetic diversity and population structure of Vernonia amygdalina, a plant species used for fodder, vegetable, and medicinal purposes in Africa and Yemen, were investigated. The results showed low genetic differentiation and gene flow between the two populations, possibly due to human-assisted gene flow.

Summary: This study identified SNPs of the Asian swamp eel from 19 wild populations in China, revealing its genetic diversity and population genetic structure. The populations were clustered into four groups, with variations in genetic diversity among them. These findings are important for the protection and breeding of the Asian swamp eel.

Summary: Indigenous cattle breeds like the Nguni play a crucial role in their native environments due to their significant adaptability traits. The genetic diversity within the bovine major histocompatibility complex and BoLA-DRB3 gene in Nguni crossbred cattle was found to be high, potentially contributing to their resistance to diseases and thermal stress. This high genetic diversity is likely associated with the adaptability and robustness of the Nguni breed, making it a valuable resource for sustainable breeding strategies in Southern Africa.

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.
