Summary: Since 2011, tropical Atlantic Sargassum blooms have caused problems in over 30 countries, with significant ecological, economic, and human-health-related issues. The Mexican Caribbean coast has been affected by massive beaching events since late 2014, occurring annually from 2018 onwards. Cleanup costs for Sargassum removal varied between municipalities and hotels, ranging from US$ 0.3-1.1 M per kilometer, with prices ranging from US$ 19-85 per cubic meter. Hotels were found to be more cost-effective than municipalities.

Summary: This study found that there is a close relationship between caprellid assemblages and algal complexity in coastal marine ecosystems. Different algal architectures host communities with different structures, affecting caprellid density and diversity. Caprellids show a clear preference for specific algal traits, contributing to increased diversity in caprellid populations.

Summary: This study quantifies the risk of ship hull fouling-mediated NIS dispersal through network analysis and numeric dispersal modeling. The removal of passenger vessels has the strongest impact on decreasing the overall dispersal capacity, highlighting the importance of enhancing management measures.

Summary: This study conducted a comprehensive analysis of the Seixas coral reef in northeastern Brazil and found that the impacts of tourism have exacerbated negative effects on the reef's marine ecosystem. The findings emphasize the importance of strategic planning and resource management to protect the biodiversity and ecological integrity of coral reefs.

Summary: China, as a global factory and trade power, faces significant invasion risks in its ports due to the discharge of ballast water from ocean-going ships, especially in the Yangtze River Delta, Pearl River Delta, and Southern Taiwan Province. The disinfection of ballast water can effectively decrease the level of invasion risk.

Summary: Sargassum golden tides bloom frequently in many sea areas worldwide, negatively impacting local marine ecology. Sargassum muticum, a common rocky shore algae with global distribution, has not been extensively studied. Higher light and/or nitrogen levels were found to enhance the relative algal growth rate, with light having a greater impact than nitrogen.

Summary: The study focused on the phenomenon of Sargassum influx on the north coast of the Mexican Caribbean, including its abundance, species composition, and chemical content. The research found that pelagic Sargassum was the main component, with its spatial distribution influenced by local environmental conditions. Significant spatial variation in the abundance of stranded biomass was observed at different locations.

Summary: This article provides an update on the epibiotic hydrozoans on Sargassum, based on a recent literature survey. A total of 131 hydrozoan species were recorded, with the majority associated with Sargassum in the Tropical Atlantic.

Summary: This study evaluated the growth response and incorporation of different arsenic species into Sargassum horneri. It was found that arsenite negatively affected algal growth rate, while all arsenic species had significant effects on growth rate. Phosphate levels influenced the uptake of arsenate, but not other arsenic species. The algae accumulated arsenate and arsenite more efficiently than MMAA(V) and DMAA(V). Low phosphate levels had a greater impact on arsenate uptake, while having less effect on other arsenic species. The algae exhibited passive modes of adsorption for all arsenic species. This information is crucial for arsenic research in marine ecosystems.

Summary: This study conducted a baseline assessment of introduced marine species along the Brazilian semiarid coast, identifying introduced species and main vectors of introduction, as well as recognizing species that pose threats to ecosystems. The study also highlighted the region as a hotspot of bioinvasion in the tropical South Atlantic.

Summary: Contemporary studies show that macroalgae biomass, specifically Sargassum wightii, rich in cellulose, can be a promising source for ethanol production. This investigation focuses on the optimization of cellulose extraction and medium components for Lachnoclostridium phytofermentans KSM 1203 for bioethanol production through consolidated bioprocessing. The alkali pretreatment and sodium hypochlorite treatment were found to effectively remove lignin and hemicelluloses, resulting in the optimal conditions for ethanol yield of 13.75 g/L.

Summary: The global evidence of phase shifts to alternate community types is of particular concern due to their fundamentally different and often novel ecosystem functions and services compared to the original community. We observed green algal mats on reefs in the Eastern Tropical Pacific, which supported a more speciose macroalgal community and facilitated growth of an associated understory macroalgal species. These results demonstrate the importance of further research on community shifts, which will become increasingly common in the Anthropocene.

Summary: Habitat classification schemes provide tools for mapping, monitoring, and assessment of habitats across regions, while also simplifying large biodiversity datasets. The functionality of HELCOM HUB in describing variation in rocky shore communities was tested, with useful results but also weaknesses observed, particularly in the classification of red algal communities. This study highlights the importance of considering the limitations of classification systems in order to avoid losing key ecosystem functions in management contexts.

Summary: The Country Compendium of the Global Register of Introduced and Invasive Species (GRIIS) is a compilation of data from 196 individual country checklists of alien species, including those that have evidence of impact at a country level. It serves as a baseline for monitoring distribution and invasion status of major taxonomic groups, and can be used for global analyses of introduced and invasive species. The Compendium allows exploration of gaps and inferred absences of species across countries, and also provides a means for updating individual GRIIS Checklists.
