- Electronic tagging and tracking aquatic animals to understand a world increasingly shaped by a changing climate and extreme weather eventsPublication . Lennox, Robert J.; Afonso, Pedro; Birnie-Gauvin, Kim; Dahlmo, Lotte S.; Nilsen, Cecilie I.; Arlinghaus, Robert; Cooke, Steven J.; Souza, Allan T.; Jarić, Ivan; Prchalová, Marie; Říha, Milan; Westrelin, Samuel; Twardek, William; Aspillaga, Eneko; Kraft, Sebastian; Šmejkal, Marek; Baktoft, Henrik; Brodin, Tomas; Hellström, Gustav; Villegas-Ríos, David; Vollset, Knut Wiik; Adam, Timo; Sortland, Lene K.; Bertram, Michael G.; Crossa, Marcelo; Vogel, Emma F.; Gillies, Natasha; Reubens, JanDespite great promise for understanding the impacts and extent of climate change and extreme weather events on aquatic animals, their species, and ecological communities, it is surprising that electronic tagging and tracking tools, like biotelemetry and biologging, have not been extensively used to understand climate change or develop and evaluate potential interventions that may help adapt to its impacts. In this review, we provide an overview of methodologies and study designs that leverage available electronic tracking tools to investigate aspects of climate change and extreme weather events in aquatic ecosystems. Key interventions to protect aquatic life from the impacts of climate change, including habitat restoration, protected areas, conservation translocations, mitigations against interactive effects of climate change, and simulation of future scenarios, can all be greatly facilitated by using electronic tagging and tracking. We anticipate that adopting animal tracking to identify phenotypes, species, or ecosystems that are vulnerable or resilient to climate change will help in applying management interventions such as fisheries management, habitat restoration, invasive species control, or enhancement measures that prevent extinction and strengthen the resilience of communities against the most damaging effects of climate change. Given the scalability and increasing accessibility of animal tracking tools for researchers, tracking individual organisms will hopefully also facilitate research into effective solutions and interventions against the most extreme and acute impacts on species, populations, and ecosystems.
- Nutrient‐driven growth and microbiome shifts in the brown alga Sargassum fluitans IIIPublication . Theirlynck, Tom; Staat, Lotte; Servania, Dhaishendra; Engelen, Aschwin; Tussenbroek, Brigitta I. van; Muyzer, Gerard; Visser, Petra M.; Amaral‐Zettler, LindaSince 2011, holopelagic Sargassum has been accumulating in a region of the tropical Atlantic now referred to as the Great Atlantic Sargassum Belt (GASB). Among the hypothesized contributors to these accumulations are the increased inputs of nitrogen (N) and phosphorus (P) in the tropical Atlantic Ocean. Little is known about the effects of N and P additions on Sargassum physiology and its microbiome. We studied the effects of N, P, and NP additions on the growth, photosynthetic efficiency, and microbiome composition of Sargassum fluitans III in a six-day experiment on the Caribbean Island of Curaçao. Sargassum fluitans III took up most nitrate and phosphate within 3days with respective uptake rates of 0.343 and 0.0399μmol · g−1 DW · h−1. Fv/Fm decreased in the control after 6days but remained constant in nutrient treatments. Growth rates did not differ significantly among treatments, but a trend in higher growth rates in the NP treatment was discerned, suggesting a possible NP co-limitation. The relative abundance of epiphytic Cyanobacteria such as Schizothrix and bacteria such as Lentilitoribacter increased under N and P addition, while heterotrophic Rhodobacteraceae decreased in abundance. Microeukaryotic communities responded with varying changes in alpha diversity, possibly steered by increased photosynthesis and growth of S. fluitans III or bacterial interactions. The physiological response to N and P and rapid change of the microbiome demonstrates that the studied S. fluitans III can quickly benefit from increased nutrient concentrations, which might contribute to its growth success in the GASB.
- New insights into car tire rubber particle toxicity: chemical composition and ecotoxicity assessment of leachate on gamete quality of the Mediterranean mussel Mytilus galloprovincialisPublication . Savino, Ilaria; Nobahar, Amir; Silva, José Paulo da; Cotugno, Pietro; Notariale, Rosaria; Corriero, Giuseppe; Uricchio, Vito Felice; Gallo, AlessandraThousands of tire rubber particles (TPs) enter the marine environment every year, contributing to microplastic pollution. The toxicity of TPs can be related to the particles themselves or chemical additives, which can leach into seawater and potentially affect marine organisms. The current study presents new insights into TPs’ impact on marine organisms’ reproductive processes. The leachates of end-of-life TPs and their adverse effects on gamete quality were evaluated by analysing the chemical compositions of seawater leachates and several gamete physiological parameters, taking the mussel Mytilus galloprovincialis as a model. Chemical analyses revealed the leaching of different metals, among which zinc showed the highest level (~3 mg/L). Organic compounds such as antioxidants, vulcanising and protective agents were annotated in leachates and correlated with the observed harmful effects on the reproductive process. The exposure of oocytes and spermatozoa to TP leachates negatively affects the gamete quality by increasing the mitochondrial activity in both gamete types and decreasing the motility of spermatozoa, which may impair the reproductive success of mussels. Since reproductive success is a key factor in species survival, this study highlights the urgent need to extend the presented research to other marine organisms.
- New evidence confirms the presence of the diamond stingray Hypanus dipterurus (Jordan & Gilbert 1880) in Chile and extends its southern rangePublication . Almendras, Diego; Villafaña, Jaime A.; Bustamante, Carlos; Contreras, Ignacio; Navarro Campoy, Ana; Dufflocq, Pablo; Rivadeneira, Marcelo M.The diamond stingray (Hypanus dipterurus) is a species of cartilaginous fish that, according to the IUCN, is globally in a vulnerable state of conservation and its populations show a decline. New records of this ray species in southern Peru and northern Chile have expanded their known range. The species is distributed in the Eastern Central Pacific, from southern California to San Andres, on the central coast of Peru, but is poorly known in Chile. Angler records mined from social media and historical data confirmed the presence of H. dipterurus along southern Peru and northern Chile, extending southward over 1250 km. A species distribution model (SDM) based on previous global occurrences combined with oceanographic layers was built to identify areas of potential and undocumented presence of H. dipterurus. The SDM showed high accuracy (area under the curve = 0.95) and predicted the potential presence of H. dipterurus along vast areas of the Peruvian and Chilean coasts, where the presence of the species was poorly documented. Comprehensive surveys are required to understand the distribution, population dynamics, habitat requirements, and threats to effective conservation efforts in the southern region of its distribution range.
- Location-dependent effect of microplastic leachates on the respiration rate of two engineering mussel speciesPublication . Uguen, Marine; Cozzolino, LorenzoMicroplastics are ubiquitous in the world’s oceans and pose serious environmental concerns, including their ingestion and the release of potentially toxic mixtures of intrinsic and extrinsic chemical compounds (i.e. leachates; MPLs). Mussels, as key intertidal bioengineers and filter-feeders are particularly susceptible to both exposure pathways. While the effects of microplastic ingestion have been widely investigated, research on the impacts of MPLs has only recently begun. This study examined the influence of MPLs derived from beached pellets collected in two separate regions, namely France and Portugal, on the respiration rates of two key ecosystem engineers, Mytilus edulis and Mytilus galloprovincialis. Possibly due to distinct mixtures of leached chemicals, unlike Portuguese-MPLs, exposure to French-MPLs significantly decreased the respiration rate of both mussel species. This research provides new insights into the physiological impacts of MPLs on bioengineer species, highlighting the importance of MP source and potential cascading effects at the ecosystem level. While we reported significant effects on mussel respiration after acute MPL exposure, future research should investigate long-term impacts and potential detoxification mechanisms to clarify the effects of MPs on mussel physiological performance and their potential consequences on specie fitness.

- Atlantic arc lander monitoring (ALaMo): an emerging network of low-cost lander arrays for ocean bottom observationsPublication . González-Pola, Cesar; Cusack, Caroline; Urquijo, Ignacio; Graña, Rocio; Rodriguez-Cobo, Luis; Sánchez-Leal, Ricardo; Nolan, Glenn; Santos, A. Miguel P.The need to establish a sustained Global Ocean Observing System (GOOS) has long been recognized by the international ocean science community. Established in 1991 and led by the Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific, and Cultural Organization (IOC-UNESCO), GOOS develops guidelines and coordinates regional alliances across the world’s ocean basins to evolve the system. The need to sustainably expand GOOS has recently gained urgency as expressed in the United Nations Decade of Ocean Science for Sustainable Development (2021–2030) Challenge 7: Ensure a sustainable ocean observing system across all ocean basins that delivers accessible, timely, and actionable data and information to all users.

Y.; Zakhama-Sraieb, Rym; Zribi, Imen; Zygadlowska, Olga M.; Jensen, Dorte KrauseMarine and salt marsh sediments contain large amounts of organic carbon (OC) and are therefore important in the global carbon cycle. Here, we collated previously published and unpublished measurements of sediment OC in marine and salt marsh sediments in European regional seas (EURO-CARBON; available at https://doi.org/10.5281/zenodo.14905489). To the extent possible the OC data were complemented by variables such as sediment porosity and dry bulk density. The EUROCARBON dataset holds 61306 individual data entries of sediment OC content from different regions of European regional seas. Around three quarters (76%) were collected in coastal and deep sea bare sediments, 18% from salt marshes, 7% from seagrass habitats, and 0.03% from macroalgal habitats. For all habitats and sediment depth layers the OC content varied between seagrass (2.37 ± 5.96 %; 3.03 %) > bare sediment (1.88 ± 2.03 %; 1.20 %). The EURO-CARBON dataset will serve as a basis for future work, and it will be an important resource for researchers, managers, and policymakers working towards protecting sediment OC pools.
- Preserving the biologically coherent generic concept of , "plant destroyer".Publication . Brasier, Clive M.; Grünwald, Niklaus J.; Bourret, Tyler B.; Govers, Francine; Scanu, Bruno; Cooke, David E.

Phylogenetic evidence has shown that the biologically distinct, obligate biotrophic downy mildews evolved from Phytophthora at least twice. Because, cladistically, this renders Phytophthora “paraphyletic,” it has been proposed that Phytophthora evolutionary clades be split into multiple genera (Crous et al. 2021; Runge et al. 2011; Thines 2023, 2024). In this letter, we review arguments for the retention of the generic name Phytophthora with a broad circumscription made by Brasier et al. (2022) and by many delegates at an open workshop organized by The American Phytopathological Society. We present our well-considered responses to the genus splitting proposals, both in general terms and in terms of the specific proposals for new genera, alongside new information regarding the biological properties and mode of origin of the Phytophthora clades. We consider that the proposals are mostly non-rigorous and not supported by the scientific evidence. Further, given (i) the apparent lack of any distinguishing biological characteristics (synapomorphies) between the Phytophthora clades; (ii) the fundamental monophyly of Phytophthora in the original Haeckelian sense (Haeckel 1877); (iii) the fact that paraphyly is not a justification for taxonomic splitting; and (iv) the considerable likely damage to effective scientific communication and disease management from an unnecessary breakup of the genus, we report that workshop delegates voted unanimously in favor of preserving the current generic concept and for seeking endorsement of this view by a working group of the International Commission on the Taxonomy of Fungi.
- The tolerance of a keystone ecosystem engineer to extreme heat stress is hampered by microplastic leachatesPublication . Uguen, Marine; Gaudron, Sylvie M.; Nicastro, Katy; Zardi, Gerardo I.; Spilmont, Nicolas; Henry, Solène; Seuront, LaurentPlastic pollution and ongoing climatic changes exert considerable pressure on coastal ecosystems. Unravelling the combined effects of these two threats is essential to management and conservation actions to reduce the overall environmental risks. We assessed the capacity of a coastal ecosystem engineer, the blue mussel Mytilus edulis, to cope with various levels of aerial heat stress (20, 25, 30 and 35°C) after an exposure to substances leached from beached and virgin low-density polyethylene pellets. Our results revealed a significant interaction between temperature and plastic leachates on mussel survival rates. Specifically, microplastic leachates had no effect on mussel survival at 20, 25 and 30°C. In turn, mussel survival rates significantly decreased at 35°C, and this decrease was even more significant following an exposure to leachates from beached pellets; these pellets had a higher concentration of additives compared to the virgin ones, potentially causing a bioenergetic imbalance. Our results stress the importance of adopting integrated approaches combining the effects of multiple environmental threats on key marine species to understand and mitigate their potential synergistic effects on ecosystem dynamics and resilience in the face of the changing environment.
