Summary: This study collected 10 paddy field carp (PFC) strains in China and used mitochondrial and microsatellite loci to analyze their genetic origin and differentiation. The results revealed that PFC strains contained genetic material from two common carp subspecies, mostly from C. c. rubrofuscus. The Ruyuan Shili carp showed lower genetic diversity, possibly due to inbreeding or intensive selection. There was also significant genetic differentiation among the analyzed strains and populations within a strain, suggesting endemic genetic properties. Overall, this study provides important implications for the management of PFC and can improve monitoring programs for this aquaculture species.

Summary: Studying the genetic structure of marine organisms is crucial for understanding their evolutionary history and potential mechanisms driving their genetic structure. In this study, the spatial and temporal genetic structure of Halophila ovalis was investigated using microsatellite loci. Each population represented a unique genetic population across time and space. Source population assignment analysis showed that most samples originated from the largest H. ovalis meadow in Qitou. Typhoon invasion may enhance propagule dispersal and subsequent local adaptation may shape the observed genetic structure. The establishment of a protected marine area and long-term monitoring program is recommended for the conservation and management of H. ovalis.

Summary: The genetic diversity among feral American mink populations in northeastern China was found to be relatively high, promoting their invasiveness and rapid evolution in the wild. This study highlights the importance of genetic characteristics in achieving high adaptation and rapid evolution in new environments for invasive species like the American mink.

Summary: Freshwater aquaculture in China has a long history and plays an important role in the country's economy. This study is focused on understanding the genetic diversity and structure of the Chinese longsnout catfish populations. The researchers used Illumina sequencing technology to identify 20 novel microsatellites, which were then used to analyze the genetic diversity of four farmed populations of the catfish species. The results showed a low level of genetic differentiation among the populations, indicating a high genetic diversity. The researchers also found evidence of admixture among the populations. This information is valuable for breeding and production practices.

Summary: The study found that farmed noble scallop populations have higher genetic diversity than wild populations, with genetic admixture caused by mixing seeds from different hatcheries. There are significant genetic differences between wild and farmed populations, and the genetic diversity can be clearly distinguished between them.

Summary: Pedigrees are crucial in selective breeding programs for managing genetic diversity and ensuring accurate genetic parameter estimates. The use of high-throughput sequencing technologies and SNPs has provided opportunities to resolve shrimp pedigrees in mass spawning cohorts. The study investigated the effects of SNPs on sibship assignment and found that high MAFs and numbers of SNPs significantly improved assignment rates and accuracies. The results showed that accurate pedigrees can be achieved through SNP-based methods, contributing to long-term response to selection in farmed shrimp.

Summary: The study revealed high genetic diversity and polymorphism in the Tripuri population, showing genetic closeness with the Gorkha population. Locus D2S1338 was found to be the most polymorphic, while TPOX was the least polymorphic. The results can enrich the existing STR database, aid forensic DNA application, and genealogical studies.

Summary: The red palm weevil is an invasive pest that can cause significant economic damage to palm trees. In order to find effective eradication strategies, researchers developed a paternity assignment strategy using microsatellite markers to study the mating system of this insect. They evaluated the reliability of their genetic tool through simulation approaches and found that it was successful in laboratory experiments but not in natural populations.

Summary: Understanding the population genetic structure of invasive species can improve the management strategies. This study analyzed the genetic structure of nutria in the Yodo River system and found that the populations may have originated from a single ancestral population. Habitat disruptions, such as floods, may have caused genetic drift and subdivision within the populations. Microsatellite DNA analysis also showed that female nutria exhibited isolation-by-distance in dispersal. Therefore, a combination of localized intensive trapping and extensive monitoring may be necessary to control nutria density.

Summary: Low earth orbit satellite laser communication is crucial in communication industry due to its high capacity and low latency. The lifetime of satellites largely depends on their battery recharge and discharge cycles. However, frequent recharging and discharging of low earth orbit satellites under sunlight and shadow leads to rapid aging. This study focuses on energy-efficient routing and proposes a genetic algorithm-based scheme to prolong satellite lifetime by about 300% while slightly sacrificing network performance with only a 1.2% increase in blocking ratio and 1.3 ms increase in service delay.

Summary: In this study, 60 stable amplified polymorphic tetranucleotide microsatellite genetic markers were screened from the whole genome sequence of C. quadricarinatus, and a multiplex PCR system suitable for parentage assignment was constructed. The results showed that these microsatellite markers had high polymorphism and could meet the requirements for parentage assignment.
