Summary: The study explores the impact of sex-specific mitochondrial evolution on gamete bioenergetics in DUI and SMI bivalve species. The findings suggest reorganized bioenergetic pathways in DUI gametes compared to SMI gametes, resulting in decreased enzymatic capacity in DUI sperm, especially at the terminus of the electron transport system. This bioenergetic remodelling fits a reproductive strategy that does not require high energy input and could potentially link with the preservation of the paternally transmitted mitochondrial genome in DUI species. The origin of this phenotype, whether from positive or relaxed selection acting on DUI sperm, remains uncertain.

Summary: In 2020, the first male-type mitochondrial genome from the clam Macoma balthica was published, revealing a unique extension in the cox2 gene and the phenomenon of doubly uniparental inheritance. This study aimed to replicate and explore the expression of the long cox2 gene, resulting in the discovery of an even longer cox2 gene and its expression pattern.

Summary: The presence of doubly uniparental inheritance (DUI) in three species of Macridiscus in Veneroida has been reported, along with the complete M-type mitogenomes. The M-type and F-type mitogenomes have similar features except for gene order. This finding supports the theory that Veneroida and Mytiloida have a more similar DUI pattern.

Summary: The study collected C. celtiformis from its type locality and determined its complete maternal mitochondrial genome. The findings confirm that the currently recognized genus Cuneopsis is polyphyletic, with C. celtiformis being closely related to C. heudei. Comprehensive sampling of all Cuneopsis species is needed for future phylogenetic analysis and to establish new genera.

Summary: The factors affecting sex determination in bivalve species, particularly Mytilus edulis, are largely unknown. This study found that environmental variations experienced by parents during gametogenesis and embryos during development can influence the offspring's sex. Temperature and sampling years were both significant factors in determining the proportion of females.

Summary: DNA and RNA sequential sequencing were used to analyze the molecular profiles of 469 Chinese melanoma patients. The study revealed that some undruggable patients could still be recognized as actionable through the use of DNA and RNA sequencing, and RNA sequencing increased the proportion of druggable fusions. The findings highlight the significance of DNA and RNA sequential sequencing in understanding the genomic landscape and clinical treatment of Asian melanoma.

Summary: By comparing different German regions, this study shows that high innovation performance in SMEs is based on a combination of learning-by-doing, learning-by-using, learning-by-interacting, and learning-by-science mechanisms. Only a partial combination of the DUI mode with the STI mode can explain high innovativeness, emphasizing that there is no universal best way to achieve high innovation, which has implications for both managers and innovation policy.

Summary: Scholars agree that firms have different innovation patterns and therefore have diverse absorptive capacity patterns. However, existing research mostly neglects other modes of knowledge absorption and the potential heterogeneity of absorptive capacity in different innovation patterns. This paper proposes a conceptual framework to analyze the heterogeneity in manufacturing firms' absorptive capacity configurations, particularly in Doing, Using and Interacting (DUI) mode of innovation. Empirical findings from three case studies in the German manufacturing industry support the heterogeneity assumption and link the differences in absorptive capacity configurations to the firm's dominant innovation pattern. This framework can provide a comprehensive basis for a more differentiated understanding and improved measurement of absorptive capacity.

Summary: The study compared the performance of dye-based qPCR and probe-based qPCR assays for the detection of bla(KPC) and mcr-1 in activated sludge (AS) samples, revealing that dye-based qPCR assays may lead to false-positive detection of bla(KPC) and mcr-1 compared to the probe-based qPCR results. Next generation sequencing (NGS) identified primer dimers and non-specific amplicons as the primary causes for the false-positive detection.

Summary: This study investigated the concentrations of zopiclone and co-ingestion with other drugs in apprehended drivers, and analyzed the half-life of zopiclone. The results showed that zopiclone was frequently detected in high concentrations in apprehended drivers and often co-ingested with other drugs. The analysis of two consecutive blood samples indicated an apparent half-life of zopiclone of approximately 3.1 to 3.8 hours.

Summary: Members of the trochoidean genus Margarella are broadly distributed across Antarctic and sub-Antarctic ecosystems. Analysis of mitochondrial and nuclear gene sequences confirmed the presence of four species, showing contrasting biogeographic patterns on either side of the Antarctic Polar Front in the Southern Ocean. Populations north and south of the Antarctic Polar Front exhibited different levels of genetic diversity, possibly influenced by Quaternary glacial cycles.

Summary: Antarctic biodiversity has been significantly influenced by rapid climatic fluctuations during the Quaternary, and studying genetic information of marine invertebrates from Antarctica reveals strong genetic structure among populations of incubating organisms and the presence of glacial refugia in organisms with limited dispersion. These findings highlight the impact of climatic fluctuations on genetic diversity distribution and evolutionary patterns of endemic organisms in the Southern Ocean.

Summary: Research shows that the diversity of enzyme forms in teleosts is mainly influenced by whole-genome duplication and selective mRNA splicing. By analyzing the transcriptional profiles of the European flounder in different tissues, we demonstrate how to preselect transcripts encoding active enzymes and find that the reported transcriptome is highly complete.

Summary: The Antarctic Circumpolar Current plays a significant role in structuring the Southern Ocean biota. However, a study on the periwinkle snail genus Laevilitorina revealed an apparent exception to the biogeographic patterns, with one species having a trans-Antarctic Polar Front distribution. The molecular analysis revealed that Laevilitorina caliginosa consists of at least seven discrete species, indicating unforeseen diversity in this widespread genus.

Summary: Two genetically different mitochondrial haplogroups of Brachidontes pharaonis have been found in the Mediterranean Sea, but there is no recombination observed between them. Moreover, the presence of both mitochondrial genomes in the generative tissues of both sexes contradicts the possibility of doubly uniparental inheritance.

Summary: The ecological patterns of macrobenthic communities in high-latitude marine environments of the Southern Hemisphere show variations at different spatial scales, mainly influenced by environmental stress gradients. In this study, the macrobenthic communities of intertidal and subtidal habitats in a glacial fjord were examined using taxonomic, ecological, and oceanographic approaches. The results revealed significant vertical patterns in taxon richness and community structure in both habitats, as well as horizontal variability at different spatial scales, with a more pronounced effect at smaller scales (quadrats). The dominant taxa in the communities also exhibited a scale-dependent distribution pattern.

Summary: Littorinid snails are important in intertidal communities and the genus Laevilitorina is distributed exclusively in the Southern Hemisphere. This study presents an updated database of 21 species, providing a comprehensive description of their known distribution. West Antarctica, New Zealand sub-Antarctic islands, and southeast shelf of Australia have the highest species richness. The study highlights the records of two species, L. pygmaea and L. venusta, which have been rarely reported before. Ongoing molecular and taxonomic studies are needed for a better understanding of the diversity and biogeography of this genus.

Summary: Quaternary glaciations have had a significant impact on the geographical ranges, population sizes, genetic differentiation and speciation rates of marine benthic organisms. The Magellan province in southern South America provides an interesting area for studying the effects of glaciations on near-shore species. New population-based analyses in Nacella species show evidence of genetic bottlenecks during glacial maxima followed by recent recolonizations and expansions.
