Summary: Recent segregation of 12 genera in the tribe Streblocladieae has updated the taxonomy of certain species belonging to Polysiphonia sensu lato, with new combinations being proposed. Six new additions to the tribe have been made based on morphological and molecular analyses, including the description of a new species and proposal of new combinations. The study also identified additional diagnostic features for two genera within the tribe, providing insights into distribution, diagnostic features for delimiting genera morphologically, and molecular evolutionary relationships.

Summary: This study describes two new species, Endoplura jejuensis and E. koreana, from Korea based on molecular and morphological analyses. Phylogenetic analysis shows that they are closely related to E. aurea from Japan. E. jejuensis is characterized by small light to dark brown thalli, while E. koreana has larger olive or yellowish-brown thalli.

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 coralline algal genus Corallinapetra is monospecific and distinct from other families and orders within the Corallinophycidae. DNA analysis supports the establishment of a new family and order for Corallinapetra, and the reassignment of L. gabrielii to Corallinapetra. Additionally, comparison of molecular data confirms the placement of L. muelleri within the Hapalidiales.

Summary: The Peyssonneliaceae is the only family in the order Peyssonneliales, encompassing widespread red encrusting algae. Through molecular phylogenies and morphological analyses, a revised taxonomic scheme for the Peyssonneliales has been proposed, uncovering underestimated diversity in Brazilian red algae.

Summary: This study collected ophiuroids from deep-sea seamounts in the South China Sea and Northwest Pacific regions and identified nine species, including two new species and seven new records. Morphological characteristics and genetic analysis revealed that species of the order Euryalida have a wider distribution in the Indo-Pacific region than expected.

Summary: In this study, 132 specimens of Ovulidae were collected, including 54 individuals of Sandalia bridgesi and three individuals of Sandalia triticea. Comparisons of genetic sequences revealed a high similarity between S. bridgesi and S. triticea, supporting the proposal that S. bridgesi should be synonymised with S. triticea.

Summary: A new species of the freshwater red algal genus Kumanoa, Kumanoa periyarensis, is described based on morphology and genetic data. It is distinguished from other species by its unique combination of morphological characters and is genetically distinct from its sister species, Kumanoa tabagatenensis.

Summary: In this study, we used an integrative approach combining cytogenetic data and sequence-based phylogeny to investigate the mechanisms of karyotype differentiation in scorpions of the genus Gint. Our results revealed significant karyotype diversity and chromosome heterozygosity in Gint species. We also found that interspecific differences in chromosome counts corresponded with genetic divergence. Furthermore, the study indicated ongoing structural changes in the genome architecture of some Gint species.

Summary: Recent research on Digenea specimens from the Mexican Atlantic revealed a new species, D. mexicana, and confirmed the presence of D. mexicana in the southern Gulf of Mexico. Species delimitation methods suggested potential new species in Australia, Japan, and Brazil. Further studies could help clarify specific delimitation issues.

Summary: This study compared the diversity, coverage, and biomass of beached seaweeds on the north-eastern and south-eastern coasts of Brazil. The results showed that while the north-eastern coast had higher species richness, the south-eastern coast exhibited higher coverage and biomass. The frequency and distribution of beached seaweeds varied significantly across beaches in Brazil, providing insights into their biodiversity and biomass and their potential economic use in the future.

Summary: The frequency and intensity of marine heatwaves are increasing globally, impacting marine ecosystems. This study evaluated the response of H. pseudomusciformis populations on the Brazilian coast to simulated heatwaves. The results showed different tolerance and physiological responses of the populations, with tropical and transition specimens being at risk of extinction.

Summary: DNA sequence analysis reveals that the current classification of Gelidium is not monophyletic, with three distinctive lineages. A new genus, Gelidiorariphycus, is described to accommodate one of these lineages. The species in this genus have similar morphologies and primarily grow on shallow subtidal rocky shores.
