Summary: The bloom-forming cyanobacteria Trichodesmium play a significant role in global oceans by contributing up to 30% of the total fixed nitrogen. During an expedition in the Gulf of Mexico, researchers observed and sampled surface slicks containing dense blooms of Trichodesmium erythraeum, which were found to have high levels of atypical free fatty acids. The unusual branching pattern of these compounds suggests that they may have a specific role in this globally important organism.

Summary: Climate driven shifts in marine species distribution are threatening the functioning and stability of marine ecosystems. Rhodoliths, as key habitats, are facing increasing threats from ocean acidification and warming. Understanding and addressing the synergistic impacts of factors like bottom trawling and environmental changes are crucial for the conservation of rhodolith ecosystems.

Summary: Italian coralline algal beds are calcareous formations that host a high biodiversity, but only seven of these sensitive habitats are part of Marine Protected Areas. Therefore, there is a need for increased research and monitoring activities to effectively protect these valuable habitats.

Summary: The spatial and temporal variability in rocky shore assemblages at multiple scales in Ilha Grande Bay, southeastern Brazil, is driven by natural factors and anthropogenic disturbances. The study found that substrate rugosity, rocky shore extension, water movement, percentage of deforested land area, and distance to urban center were the environmental variables that most explained spatial patterns of the assemblages. Patterns of horizontal variation were not fully consistent between depths, indicating the complexity of factors driving variability in rocky subtidal assemblages.

Summary: The study utilized fine-tuning pretrained Convolutional Neural Networks (CNNs) on coralline algae images to explore a new classification tool. The calcification patterns were shown to have high diagnostic value for class predictions, and CNNs were proved to be a valid support for morphological taxonomy in coralline algae.

Summary: Research on rhodolith beds is relatively limited compared to other coastal vegetated habitats, but it is increasing over time. The majority of research comes from the USA, with a shift in focus from geological and paleontological aspects to molecular taxonomy, conservation, and ecophysiology. Research on ecosystem services and carbon sequestration in rhodolith beds is still limited.

Summary: Phymatolithon Foslie is a significant genus of crustose coralline algae, which plays an important ecological role in marine ecosystems worldwide. A new species of Phymatolithon, named Phymatolithon abuqirensis, was discovered in the Mediterranean Sea through molecular and morphological analyses, increasing the total number of known Phymatolithon species in the region to six.

Summary: The growth and CaCO3 production of rhodoliths in the SW Atlantic Ocean remain poorly quantified, making it difficult to relate measurements with biomass estimates. Suboptimal conditions may clarify how harsh environments influence nodule growth and abundance, independently affecting growth and abundance. Overall, fast growth rates and relevant structural roles are not necessarily associated with dense rhodolith assemblages, and ecological assessments should consider the dynamics of both individual nodules and the whole population.

Summary: The study revealed that rhodolith beds are sensitive to sediment and environmental impacts, where rhodolith density and invertebrate diversity and density are influenced by environmental factors. In cleaner beaches, polychaetes and echinoderms dominate, while suspension feeders, particularly bivalves, are dominant in more polluted beaches.

Summary: A comparative study between a centuries-old manmade structure and the nearest natural reef at St. Eustatius in the eastern Caribbean found that the artificial reef had significantly lower species richness and fewer competitive interactions than the natural reef. The artificial reef was dominated by crustose coralline algae and zoantharians, while the natural reef was dominated by turf algae and fire corals. Significant differences in species composition were also found between exposed and sheltered sites on both reefs.

Summary: Coralline algae are important ecological players in the world's oceans and can serve as climate records. However, most algal-based paleo-reconstructions are only available from mid- to high-latitudes, with few examples from low latitude and temperate regions.

Summary: The study found that the impact of microplastic on corals depends on the type of microplastic, coral species, and temperature. Microplastic fibers reduced the photosynthetic capability of Acropora sp., while exposure to microplastic spheres significantly improved photosynthetic performance in Seriatopora hystrix.

Summary: Genomic analysis revealed that maerl beds of P. calcareum in the north-east Atlantic are geographically structured due to limited dispersal potential and connectivity. Unique genetic diversity of P. calcareum in the Fal Estuary, south-west England, was shaped by geographical isolation and lack of gene flow with other populations, separate from closely related species. Preserving the accumulated genetic diversity of P. calcareum is crucial for enhancing resilience to climate and environmental changes, requiring conservation management at a site-by-site level in western Europe.

Summary: The study reveals that stable and persistent cold climatic conditions are correlated with transitions to viviparity in squamates, as shown by the correlation of parity mode with palaeoclimate and background diversification. This suggests that trait evolution is closely tied to squamate lineage diversification, and transitions in parity mode may depend on environmental and intrinsic effects.

Summary: The occurrence and proliferation of reef-forming corals are essential for biodiversity and ecosystem services. Understanding the ratio of live : dead coral through the 'Goldilocks Principle' can help model coral growth and stability, showing how corals optimize their habitat through engineering. By utilizing particle imaging velocimetry and numerical modelling, we can investigate the future of coral reef structures and the biodiversity they support.

Summary: This article consists of three commentaries discussing the state, issues, and solutions of Integrated, Coordinated, Open, Networked (ICON) principles in the AGU section paleoclimatology and paleoceanography (P&P). The commentaries focus on global collaboration and data sharing, local knowledge and global interaction, and research and application of data. Incorporating ICON principles into research proposals can enhance P&P projects. Networking is a promising approach to overcome interdisciplinary and integration challenges.

Summary: By studying natural hybrids between oviparous and viviparous common lizards, researchers uncovered the genetic basis and functional genes related to parity mode, including progesterone-binding functions and pathways for tissue remodelling and immunity. Viviparity was found to involve more genes and complex networks compared to oviparity, with genes active in pregnancy in mammals, squamates, and fish showing associations with immunity, tissue remodelling, and blood vessel generation. This suggests that pre-established regulatory networks are repeatedly recruited for viviparity and shared at deep evolutionary scales.

Summary: Investigated the photo- and chromatic acclimation and morphological change of red coralline algae in mesophotic depths. Results showed that these algae can maintain photosynthetic function under decreasing light intensity and spectral availability, but this leads to smaller and less complex thalli. The photo-acclimatory response is conserved at least at the Order level, while chromatic acclimation is not depth-dependent. Use of photoprotection is necessary at 65 m depth, while optimal light levels are met at 86 m.
