Summary: A new genus and species of brown algae, Setoutiphycus delamareoides gen. & sp. nov., was described in this study. This species, similar to Delamarea but distinct in certain aspects, was found in the Seto Inland Sea. It is suggested that the species may have survived in refugia in southern Japan during the last glacial maximums, rather than evolving within the Seto Inland Sea itself.

Summary: The genus Clostridium is diverse and includes species like C. cocleatum, C. ramosum, C. spiroforme, and C. saccharogumia. These species form a distinct cluster within the family Coprobacillaceae in the order Erysipelotrichales. Based on phylogenetic, genomic, phenotypic, and chemotaxonomic information, it is proposed that these species be transferred to a new genus called Thomasclavelia.

Summary: Two novel aerobic and obligately acidophilic bacteria, Paracidobacterium acidisoli and Alloacidobacterium dinghuense, were isolated from forest soil in Dinghushan Biosphere Reserve in Guangdong, China. The discovery of these new bacterial genera and species is significant for understanding acidophilic bacteria in the environment.

Summary: Factors such as atmospheric CO2 increase, cold water temperatures, respiration, and freshwater inputs contribute to enhanced acidification in Arctic waters. The effects of ocean acidification on the Arctic Ocean ecosystem, whether from anthropogenic or natural sources, remain highly uncertain. Studies on pelagic sea snails as biological indicators showed shell dissolution and advanced levels of dissolution occurred at all stations in the Amundsen Gulf region, indicating widespread exposure to corrosive waters and significant impact on the majority of the population.

Summary: This study identified three fungal strains pathogenic to aphids and whiteflies in Argentina as Lecanicillium uredinophilum, representing the first documentation of this fungus in hemipteran insects and outside of Southeast Asia, particularly in the Americas. Through a combination of morphological and molecular taxonomy analyses, it was proposed that the entire species L. uredinophilum should be reclassified into the genus Akanthomyces, leading to the introduction of a new taxon, Akanthomaces uredinophilus comb. nov.

Summary: The retreating ice cover of the Central Arctic Ocean has raised concerns about the future fisheries in the region. However, little is known about the presence of harvestable fish stocks in this vast ecosystem. A recent study found a 3170-kilometer-long deep scattering layer (DSL) with zooplankton, small fish, and low abundances of Atlantic cod in the Atlantic water layer of the Eurasian Basin. The potential fish abundance was found to be far below sustainable levels and is expected to remain so due to the low productivity of the Central Arctic Ocean.

Summary: A new species Lobophora tsengii is described from Bach Long Vy (Bailongwei) Island, Haiphong Province, Vietnam, with morphological similarities to plants from Hainan Island, China. Molecular phylogenetic analyses show that the specimens from the island form a clade separated from other Lobophora species.

Summary: This study describes the life cycles of two mesopelagic carnivorous copepods and their vertical distributions and population growth. The life cycles of Paraeuchaeta glacialis and Heterorhabdus norvegicus show different characteristics, with a skewed sex ratio towards females in P. glacialis and a complete life cycle within 1 year for H. norvegicus.

Summary: This study investigated the geographic and diel variations in population structure, body size, grazing activity, and fatty acid composition of Calanus glacialis/marshallae in the Pacific Arctic Ocean during autumn 2019. The results showed that the abundance of C. glacialis/marshallae was higher on the slopes and lower on the shelves. C4 and C5 dominated on the southern and northern shelves, respectively, and the slope population had high concentrations of diatom-derived EPA. The basin population had higher early copepodite stages and both small and large forms of C5. The small form exhibited diel grazing activity while the large forms did not.

Summary: Colpomenia borea sp. nov. was described based on morphological observations and molecular analyses using mitochondrial cox3 and chloroplast rbcL genes. It is distinguished from other Colpomenia species by its small globular to ovoidal thallus and thin thallus membrane. C. borea is epiphytic on the brown alga Stephanocystis in protected areas. The phylogenetic analysis showed that C. borea is a distinct species, closely related to C. peregrina.

Summary: This study identified 11 independent genetic lineages of Ralfsia-like taxa, leading to the proposal of a new classification unit, Pseudoralfsiaceae, and two new genera, Pseudoralfsia and Nuchella. Additionally, species of Pseudoralfsiaceae can be distinguished from Ralfsia sensu stricto (Ralfsiaceae) mainly by DNA sequences and by consistently having frequent hair pits, and typically unsymmetrical thalli.

Summary: Specimens of Spyridia 'filamentosa' from Southern New England and New York were sequenced for mitochondrial COI-5P and chloroplastic rbcL genes, showing distinct differences from Mediterranean specimens. As a result, a little-known species name, Spyridia americana Durant, was assigned to specimens collected from the northeastern coast of the United States.

Summary: Partial rbcL sequences were obtained from type specimens of Lithophyllum coarctatum and L. gardineri. Despite morpho-anatomical similarities, phylogenetic analyses confirmed that both species belong in Porolithon. A novel epiphytic species, P. epiphyticum sp. nov., from Cocos-Keeling Islands was also identified.

Summary: Molecular analyses have revealed discrepancies in Australian taxa previously classified as Plocamium cartilagineum with the species from its northern hemisphere type locality. After examining and designating a lectotype for Plocamium pusillum, it has been resurrected as a distinct species genetically and morphologically, differing from authentic P. cartilagineum.

Summary: In the last decade, molecular tools have revealed previously unrecognized taxa in Bermuda's marine flora, especially among the Rhodophyta. Misidentified species have been reclassified and many novel species have been discovered. The `Laurencia complex' has also been modified globally, with five of the eight recognized genera found in Bermuda. The study presents new species and revises the classification of existing ones using genetic sequencing.

Summary: By screening DNA from 285 coralline crusts in Canada and adjacent waters, the distribution range of Porphyra corallicola was found to be far beyond previous knowledge. In addition, it was found that other species also exist only in the Conchocelis stage. The further development of this method will facilitate the study of Conchocelis stages in nature, greatly enhancing ecological knowledge of bangialean species.

Summary: The Acrotylaceae, a red-algal family composed of six genera, lacks common habits and vegetative features among them, with cystocarps being the most unifying characteristic. Molecular studies reveal that the family consists of two subfamilies, Acrotylaceae and the newly proposed Clavicloniaceae. The South African genus Reinboldia, previously included in Acrotylaceae, is now considered questionable for inclusion in the family.
