Summary: Cryptic diversity is common among marine macroalgae, and the use of molecular tools has led to the discovery of many new species. This study aimed to resolve the taxonomy of a complex of species within the turf-forming red alga Polysiphonia scopulorum, as well as related species, using both molecular and morphological information. The researchers found multiple new species and genus assignments within this complex, highlighting the importance of molecular tools in accurately identifying and classifying marine macroalgae.

Summary: Several strains of unicellular cyanobacteria originally identified as Synechocystis sp. from St. Petersburg State University culture collection have been reclassified into a new genus Altericista, proposing three new species. Altericista, morphologically similar to Synechocysis, is distinct in its ability to produce accessory chlorophylls d and f in cultures exposed to far-red light, showing ecological, biochemical, and physiological differences from Synechocystis.

Summary: A large amount of research has focused on commercializing carotenoids produced by Haematococcus, but without a proper phylogenetic assessment. The existence of cryptic diversity in the genus can complicate pigment studies. By analyzing molecular markers and conducting morphological studies, we identified a new species, H. privus, exclusively found in North America. Our findings also suggest that certain morphological traits can be helpful in distinguishing different Haematococcus lineages.

Summary: To resolve the uncertainty around taxonomic classification of Sporolithon species, targeted PCR sequencing was conducted on historical and recently collected specimens. The results confirmed the existence of distinct species and identified previously misclassified specimens. DNA sequencing of type specimens of coralline species was shown to be the most reliable method for accurate naming.

Summary: This study used DNA sequences and morphological observations to confirm that Cystoclonium obtusangulum actually consists of two distinct species, leading to the proposal of a new genus name Meridionella. These two species are morphologically similar but have different distributions, one found in South America and the Falkland Islands, and the other occurring in Antarctic waters.

Summary: The use of molecular tools in red algal diversity surveys often reveals the existence of undescribed species. We report a new Macaronesian turf-forming red alga in the genus Melanothamnus. This new species differs from its congeners by sequence divergence in the rbcL gene and is suggested to be endemic to Macaronesia.

Summary: The simple morphology of Selenastraceae family members in freshwater phytoplankton has led to misidentifications, but molecular tools are helping to untangle their phylogeny and reveal new genera and species. The study introduces a new species, Viridiparva madeirensis, within Selenastraceae with unique characteristics and highlights the importance of revising genera within the family. The research contributes to clarifying the phylogeny and taxonomy of Selenastraceae and adds genetic sequences of neglected nanophytoplankton to GenBank.

Summary: Ostreobium is a siphonous green alga that burrows into calcium carbonate substrates and forms green bands on coral skeletons. It plays a major role in carbonate reef bioerosion and contributes to the coral's nutritional needs. This review summarizes knowledge on Ostreobium's biology, including its morphology, biodiversity, photosynthesis, bioerosion mechanisms, and its role in the coral holobiont.

Summary: Through the study of marine heterokont algae collected from intertidal pools in Australia, we discovered seven new genera of algae, including three new scientific species. By analyzing the genetic sequences, we identified three new species. This study provides evidence for the diversity of heterokont algae and supports the use of an external membrane as a defining morphological feature.

Summary: This study combines molecular and morphological analyses to study red algal taxa. It finds that populations of Symphyocladiella parasitica from northern and southern Europe represent different species. A new species, Symphyocladiella arecina sp. nov., is proposed for samples from southern Europe, and a new genus, Deltalsia, is proposed for the British samples.

Summary: In this study, the researchers used chemical imaging and microbiome characterization to investigate the impact of physicochemical gradients on the coral skeleton microbiome. They found that the microbial community in the coral skeleton was influenced by the physicochemical environment, and the microbiome composition was linked to the abiotic conditions.

Summary: DNA sequencing was used to study the taxonomy of two Australian red algal species, one of which was found to be identical to the European Aphanocladia stichidiosa. However, it was unexpectedly classified in the Lophurella genus rather than Aphanocladia. Another Australian species was described as L. pseudocorticata sp. nov. The study highlights the importance of using phylogenetic approaches to identify and determine the native ranges of introduced species.

Summary: This study focuses on the bacterial communities associated with cultured strains of 5 Ostreobium clades using 16S rRNA sequencing. The research reveals the preferential associations between Ostreobium and 34 bacterial taxa, which are also present in their natural environment. The study also shows a significant congruence between the Ostreobium phylogeny and the community composition of its tightly associated microbiome.

Summary: The introduction of new non-indigenous species in Spanish marine waters was studied. National baseline inventories were compiled and updated for the three subregions, and a total of 574 species were identified. The majority of these species were invertebrates and primary producers. The highest percentage of alien species was reported in the Bay of Biscay-Iberian Coast, followed by the Western Mediterranean Sea and Macaronesia. There were more cryptogenic species in the Western Mediterranean Sea compared to the other two subregions. The pathway with the highest number of records was 'transport-stowaway', followed by 'transport-contaminant' related to mariculture.

Summary: This study highlights the impact of kelp forest decline on the macroalgal understorey, showing that traditional alpha-diversity indicators may not detect significant differences between healthy and degraded reefs. Instead, small-scale spatial beta-diversity decreases significantly due to deforestation, indicating a more comprehensive assessment of the consequences of kelp forest decline.

Summary: The study focuses on analyzing the biological and ecological traits of European seaweeds and organizing the data within a standardized framework. A trait database containing 45,175 records for 21 traits was created, providing valuable information for future research on seaweed diversity, evolution, and response to global changes. The data are publicly accessible and will contribute to the development of ecosystem models and marine conservation policies.

Summary: Ostreobium is a green alga that lives in calcium carbonate substrates and can survive in low light and low oxygen conditions. It is a major contributor to the erosion of coral reefs and plays a role in the nutrition of corals. Understanding the biology of Ostreobium and its role in coral reefs is important for the study and conservation of these ecosystems.

Summary: Effective monitoring of non-indigenous seaweeds is important, but there is still uncertainty about the status of many species. This study analysed the status of presumed non-indigenous seaweed species in the Mediterranean Sea, Northeast Atlantic Ocean, and Macaronesia. A list of 140 undisputed non-indigenous species was produced, while the status of 87 species remained unclear. The study also found significant variation in the diversity of non-indigenous species between geographic regions. The current measures and policies are insufficient to battle the introduction and spread of non-indigenous species in the study area.
