Summary: This study assessed different perspectives to establish a stable taxonomic framework for Ulva green seaweed, finding that species delimitation methods using the tufA gene were the most consistent. DNA-based species delimitation often disagreed with traditional morphology-based definitions, and biological species concepts were generally narrower than DNA-based delimitation. Although molecular markers improved our understanding of Ulva diversity, names associated with DNA sequences in public databases are unreliable, highlighting the need for further research in tropical regions.

Summary: The morphology, ultrastructure, and phylogeny of eight soil diatom strains assigned to the Pinnularia genus were studied, with six new species identified and described for the first time. Molecular phylogeny reconstruction grouped the new strains with different subclades within Pinnularia. Fatty acid profiles of the algae cultured on specific medium showed high yields of saturated and monounsaturated fatty acids, making the novel Pinnularia strains promising feedstock for biofuel production.

Summary: This study summarizes the research areas and trends of diatom DNA meta-barcoding for water quality monitoring. It reveals that developed nations, led by France, dominate the research in this field. DNA meta-barcoding is found to be more effective than morphological methods in determining diatom community structures. However, there are biases between morphological and molecular based diatom indices.

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: This study reviews the species diversity of Basidiomycota in different lifestyles and habitats, highlighting the higher publication rate of new species in lichenicolous yeast-like taxa and the lower discovery rate of plant parasitic basidiomycetes. The establishment of a comprehensive taxonomic system through a global initiative by mycologists is found to be important for promoting and standardizing the recognition of taxa. Estimates suggest that over 54,000 species of Basidiomycota will be discovered by 2030, highlighting the significant gap between described and unknown diversity in this phylum.

Summary: This study presents a new classification of the catfish family Ariidae based on a total-evidence hypothesis. The classification incorporates data from both morphological and molecular characters, involving 249 morphological and 5603 molecular characters from 131 species. The proposed classification identifies named taxa that are supported by maximum parsimony, maximum likelihood, and Bayesian inference analyses.

Summary: The study investigates species distribution patterns in the Brazilian Marine Province (BMP) using a multi-taxa approach and environmental factors. The results show that environmental variables explain a significant portion of species clustering patterns, with sea surface temperature, water turbidity, and current velocity being important factors. The study also reveals a latitudinal gradient of species richness and identifies distinct areas in terms of environmental and biotic data.

Summary: Historical identification of non-geniculate coralline algae in the northwestern Gulf of Mexico was based on morpho-anatomy. Recent studies combining DNA sequencing and SEM have discovered previously undocumented diversity of non-geniculate coralline algae in mesophotic hard bank communities. However, total diversity estimates are still incomplete and more species are yet to be described.

Summary: Molecular sequence analyses revealed that specimens previously identified as Cirrulicarpus sp. in southeastern Brazil are actually more closely related to the genus Meredithia. A new species, Meredithia dichotoma, is proposed to accommodate this rare and endemic taxon. It is characterized by its unique morphology and sequence divergence from its congeners. This finding represents the first record of a Meredithia species in Brazil and in the western South Atlantic, contributing to the diversity of the red algal family Kallymeniaceae.

Summary: The taxonomy of the calcified marine red macroalgal genus Jania has traditionally relied on the analysis of morpho-anatomical characters. However, high levels of morphological plasticity among Jania species and overlapping diagnostic characters have made species identification challenging. Molecular methods have been used to test morphology-based classifications, delineate species, and solve taxonomic issues. A recent morphology-based taxonomic study of Jania in Australia identified five species and two varieties. Dual-marker phylogenetic and species delineation analyses of Jania herbarium specimens confirmed the molecular distinction of several species and also revealed potentially new species. Further molecular phylogenetic analyses and the development of new markers are needed for a more comprehensive understanding of Jania species.
