Summary: Fisheries and aquaculture practices are posing genetic risks to marine fish populations, underscoring the importance of integrating genetic information into management. Despite lower genetic diversity within populations, the lack of genetic structuring suggests a unique genetic stock with high dispersal capabilities.

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: This study investigated the level of microplastics in the surface water and estuarine mullet Mugil cephalus from 23 estuary areas in southern China. The average abundance of microplastics in the water was 18,261 items/m³, and in the fish, it was 7.2 items/individual. These findings indicate significant pollution due to microplastics, which may impact the health of aquatic species and humans. Therefore, monitoring and managing pollution caused by microplastics in estuaries is highly recommended.

Summary: This study is the first to investigate the presence and physicochemical properties of microplastics in mullets from coastal areas in East Java, Indonesia. The study found that microplastics were present in the gills, stomach, and intestines of the fish samples, with varying abundances and characteristics. Multiple types of polymers and additives were identified in the microplastics.

Summary: This study analyzed the sequences and haplogroups of the mitochondrial DNA control region in a typical Dong population in Guizhou, China. The findings revealed 180 haplotypes assigned to 97 different haplogroups. The Guizhou Dong showed the closest genetic relationship with the Han and Miao populations in China, as well as with the Punjab and Kashmiri populations in Pakistan and other world populations.

Summary: Phoma stem canker, caused by the fungi Leptosphaeria maculans and L. biglobosa, is a devastating disease in oilseed rape production. This study investigated the population structure and genetic variation of L. biglobosa in China. The results showed significant genetic differentiation between different L. biglobosa populations, and the dominant group in Chinese populations (Group III) exhibited higher pathogenicity compared to Group I.

Summary: This study assessed the genetic diversity and population structure of Artemia franciscana populations from different sampling sites in the southeast coast of India using the mtDNA control region. Results revealed clear sequence divergence between populations, with distinct genetic clusters identified. Unique haplotypes associated with specific habitats were observed, indicating sequence divergence within homogeneous populations of A. franciscana despite similar geographic zones.

Summary: This study investigated the populations and stocks of Chelon auratus and Mugil cephalus in the Koycegiz Lagoon (Mediterranean coast). The length-weight relationships, growth performances, and mortality rates of the two species were determined. The study concluded that both Chelon auratus and Mugil cephalus in the Koycegiz Lagoon are overexploited.

Summary: Genetic diversity and population structure of Coreius guichenoti populations in the upper reaches of the Yangtze River were analyzed to investigate the impact of dam constructions. While genetic diversity did not significantly differ between 2009 and 2019, population structure became stronger and some populations showed significant differentiation in 2019. Populations at higher elevations were found to be more vulnerable than those at lower elevations, calling for conservation and restoration efforts such as fish passage and artificial breeding.

Summary: Moderate levels of genetic diversity and differentiation were found in Anisoptera costata. Population divergence during the Younger Dryas was detected. The anthropogenic disturbance significantly impacted the genetic diversity of the species in low tropical forests.

Summary: The study conducted on Indo-Pacific bottlenose dolphins in Perth found four behavioral communities with similar genetic structures but small differentiation due to related individuals within communities. The high levels of contemporary migration and related individuals among communities suggest a panmictic genetic population with continuous gene flow. Despite genetic similarity, each social community should be considered a distinct ecological unit for conservation due to exposure to different threats and occurrence in different habitats.

Summary: This study compared the resolution of mitochondrial COI and nuclear SNP markers for detecting population structure among stream insects at small spatial scales. The results showed that both types of markers can provide suitable initial estimates of fine-scale population genetic differentiation in stream insects.

Summary: Population genetic structure of Sardinella lemuru in Philippine waters was examined using mitochondrial DNA markers. The study revealed genetically structured sympatric haplogroups across the archipelago, but little genetic differentiation was inferred based on geographic location of samples.

Summary: This study investigated the health status of mugil fish in the northeastern region of Manzala lake, finding that heavy metals in water and sediments exceeded permissible limits for human consumption, adversely affecting the mugil's health, especially with severe histopathological damage in the gills, muscles, and liver during the autumn season. Monitoring environmental pollution is essential to improve mugil fish health.

Summary: In this study, the phytochemical analysis of Asparagus lycopodineus was conducted for the first time, leading to the isolation of 14 compounds. Among them, five compounds have never been found in the Asparagus genus before. Additionally, the results highlight the close evolutionary relationship among A. lycopodineus, A. cochinchinensis, and A. filicinus.
