Summary: Studies on genetic and morphological variability of Clibanarius antillensis along its distribution did not show any population structure, possibly due to high dispersal potential of the species and lack of barriers to gene flow. Additionally, high genetic diversity was observed, mainly for the COI gene, suggesting that the species has been experiencing constant expansion in the last 700,000 years without any genetic bottleneck.

Summary: This study collected and analyzed 1437 specimens of Minuca burgersi from 105 locations in the western Atlantic Ocean to examine diversity in a species with a large geographic range. The research revealed considerable biological divergence among populations of M. burgersi in the Caribbean and South America, with genetic differences between clades coinciding with geological events and environmental factors.

Summary: Streptomyces isolates were collected from ecologically similar habitats in 13 provinces in Southern China. Based on their 16S rDNA sequences, they were classified into 96 operational taxonomic units, including eight potentially new species. The phylogenetic analysis revealed that isolates with similar geographical distributions clustered together. The beta diversity of Streptomyces showed a latitudinal diversity gradient and did not change significantly with geographic distance.

Summary: A new species of freshwater crab, Candidiopotamon penglai, was discovered in eastern Taiwan. It is morphologically similar to C. rathbuni from western Taiwan but can be distinguished by the morphology of the male first gonopod (G1) and mitochondrial DNA. The genetic differentiation and morphological differences between the two species within Taiwan are discussed, and a key to the species of Candidiopotamon is provided.

Summary: The fiddler crab Tubuca arcuata is widely distributed across East Asia and northern Vietnam. Two main clades of this species were identified based on mitochondrial genes, and the role of the land bridge barrier during glaciations in their cladogenesis was suggested. The distribution pattern of the crab is shaped by the Paleo-Kuroshio Current and other warm currents during the reproduction season.

Summary: This study genetically compared specimens of Acetes americanus collected in South America with Acetes americanus carolinae sampled in North America. The results showed clear genetic differences between them, supporting the idea that A. a. americanus and A. a. carolinae are distinct subspecies. Additionally, a new subspecies, A. a. Brazil 2, was discovered on the Brazilian coast. Further research is needed to confirm and describe this new subspecies.

Summary: The genetic analysis of 211 samples of Loliolus (Nipponololigo) beka revealed two distinct lineages, Lineage A and Lineage B. Morphological observations and statistical analysis further confirmed the genetic differentiation, showing significant differences in various characteristics between Lineage A and Lineage B. This study provides additional evidence for the presence of the cryptic species of L. (N.) beka in the coastal areas of China.

Summary: The study revealed that Mobilids show five distinct evolutionary lineages/species at the molecular level. Different Mobilids are highly correlated with their planarian hosts, suggesting that host organisms may provide isolated niches that facilitate speciation of their epibiotic ciliates.

Summary: This study provides a comprehensive phylogeographical analysis of the gastropod species Thaisella chocolata along the Southeast Pacific coastal region. The results show high genetic diversity but lack of population differentiation within the survey area. The study also reveals two ancestral demographic expansions in the history of the species.

Summary: The study aimed to investigate the genetic diversity of Angiostrongylus cantonensis in Ecuador. The analysis revealed that all A. cantonensis isolates from different provinces in Ecuador were genetically identical and clustered with isolates from the USA and Asia. This suggests that the invasion of A. cantonensis in Ecuador may have occurred recently and originated from Asia through the USA. Further research should include samples from neighboring countries.

Summary: This study investigated the genetic variation and evolutionary parameters of Thrips tabaci populations in the United States. The results revealed high genetic diversity and structure of the onion thrips, which is a significant pest that causes severe damage and acts as a vector of plant viruses.

Summary: This study utilized various methods to classify and identify fish species in the Maroni Basin, resulting in the discovery of 25 new candidate species and revealing more cryptic diversity. Genetic divergence showed significant differences between different regions, possibly due to lower levels of connectivity. A new method of ordination of genetic landscapes helped effectively categorize species based on their patterns of genetic divergence.

Summary: Genetic stock identification (GSI) is an important management tool for Pacific salmon, providing rich genetic baseline data across the Pacific Rim. Analyzing data from chum salmon populations, it was observed that Japanese/Korean populations had the greatest impact and SNP selection was based on predicted structures.

Summary: This article introduces a method for assessing the effectiveness of fishery stock enhancement programs using a computer program and a two-stage sampling strategy. The authors used the example of released Japanese flounder to estimate commercial landings and recapture rate, and also determined the optimal sampling strategy through predicting standard errors of landings.

Summary: This article introduces a method of using exploratory analysis to infer multitrait coadaptation during population range expansion. By using the population-specific fixation index and principal component analysis, the history, environmental changes, and multiple trait selection of populations can be revealed. The study found that exploratory analysis can reconstruct the pattern of environmental selection missed by traditional single trait analysis.
