Abstract Since 2017, the invasive brown alga Rugulopteryx okamurae has posed significant biological, ecological, and socio-economic challenges in Morocco due to its rapid proliferation accumulation. This study explores antimicrobial antibiofilm properties chemical composition. Methanol, chloroform, ethyl acetate (EtOAc) extracts were evaluated for antibacterial activity against six human pathogens, including clinical reference strains of Escherichia coli Staphylococcus aureus. Fourier-transform infrared spectroscopy (FT-IR) identified functional groups such as hydroxyl (O-H), carbonyl (C = O), polysaccharides, indicative bioactive compounds. Gas chromatography-mass spectrometry (GC-MS) revealed key components: oleic acid butyl ester EtOAc extract, methyl tetradecanoate chloroform pentadecanoic methanolic extract. The potential was assessed using microdilution growth curve assays, with minimal inhibitory bactericidal concentrations ranging from 3.12–50 mg/mL. Growth analysis showed bacteriostatic effects through lag phase extension rate suppression. extract demonstrated highest activity, reducing biofilm formation by 73% E. (clinical strain TT-23) 70% S. aureus 70). These results suggest that R. contains compounds promising properties, potentially valuable mitigating impacts while offering applications development.

Invasive alien species are a major worldwide driver of biodiversity change. The current study lists verified records non-indigenous (NIS) in European marine waters until 2020, with the purpose establishing baseline, assessing trends, and discussing appropriate threshold values for good environmental status (GES) according to relevant legislation. All NIS were by national experts trends presented six-year assessment periods from 1970 2020 Union Marine Strategy Framework Directive. Altogether, 874 have been introduced Mediterranean Sea North-East Atlantic Ocean hosting most introductions. Overall, number new introductions has steadily increased since 2000. annual rate reached 21 seas within last period (2012–2017). This increase is likely due human activities research efforts that intensified during early 21st century Seas. As Europe not environmentally, nor geographically homogenous, setting GES requires regional expertise. Further, once management measures operational, pathway-specific would enable effectiveness such measures.

Biological invasions, resulting from human activities, exert substantial impacts on ecosystems worldwide. This review focuses marine invasive alien species (IAS) in Europe, examining the current state, proposing strategies to address problem, and offering recommendations for enhanced management. Effective management of biological invasions relies accessible, accurate data inform decision-making. Information systems such as European Alien Species Network (EASIN), Aquatic Non-Indigenous Cryptogenic (AquaNIS), World Register Introduced Marine (WriMS) provide comprehensive databases IAS, but their sustainability requires long-term maintenance, continuous updates, support. Most countries lack specific monitoring programs standardization improvement methods are needed. Port plays a vital role early detection new arrivals, recent advancements molecular techniques show promise effective IAS monitoring. Risk screening tools commonly employed rank taxa based invasiveness potential regions, variations protocols can yield inconsistent results. impact assessments highlight resource competition, novel habitat creation, predation primary mechanisms negative biodiversity, while creation habitats represents key mechanism positive impacts. Preventing introductions is critical, measures ballast water treatment implemented reduce likelihood introductions. However, understanding introduction pathways remains uncertain many IAS. Eradication control efforts have limited success, emphasizing need biosecurity measures. Climate change, especially ocean warming, intensify native ecosystems. In climate change hotspots, some tropical aliens may, however, compensate loss thermally sensitive natives with similar traits. Therefore, it imperative consider interactions between developing conservation strategies. Enhancing Europe entails i) securing adequate funding, ii) expanding list Union Concern adequately cover iii) learning successful practices, iv) sustaining information systems, v) improving warning innovative technologies, vi) enhancing prediction models, vii) conducting integrated mapping cumulative impacts, considering benefits ecosystem functioning services.

This work presents refined, updated subregional and regional non-indigenous species (NIS) inventories for the Mediterranean Sea, validated by national taxonomic experts, with records observed until December 2020. These datasets will be used as baselines implementation of Integrated Monitoring Assessment Programme (IMAP) Quality Status Report 2023. In total, 1006 have been found in marine brackish waters. The highest numbers NIS were Israel, Türkiye, Lebanon Italy. Approximately 45 categorized data deficient, either due to lack consensus on their alien status or validity identification. Polychaeta, Foraminifera macroalgae groups controversial species. There was a general increase yearly rate new introductions after late 1990s, which appears slowing down last decade, but this may confounded reporting lags differential research efforts. Between 1970 2020 there has steep proportion shared present throughout all four subregions, are predominantly transported via shipping recreational boating. While Lessepsian gradually spreading westwards northwards, is still considerable invasion debt accumulating eastern central Mediterranean.

The Mediterranean Sea, a biodiversity hotspot, faces significant threats from non-indigenous species (NIS), which drive changes. Over the past century, introduction of NIS has accelerated due to maritime traffic, aquaculture, and interoceanic canals, fostering biological invasions. Marine protected areas (MPAs), established preserve biodiversity, are increasingly impacted. This review quantified characterized French MPAs, analyzing macroalgae distribution based on existing literature authors’ observations. Results revealed widespread occurrence, with highest richness in strictly regulated MPAs; their proximity large harbors highlights paramount importance pathways. In addition, there is knowledge gap regarding within complicating efforts monitor study these effectively. These findings highlight challenges monitoring managing invasions urgent need for controlling primary secondary invasion pathways, outside international collaboration control them, enhanced funding monitoring. Without adaptive management, even MPAs vulnerable escalating impacts invasive species.

The introduction of new non-indigenous species (NIS) in Spanish marine waters is addressed under Descriptor 2 the European Union’s Marine Strategy Framework Directive. National baseline inventories NIS have been compiled and updated for three subregions (Western Mediterranean Sea, WMED; Bay Biscay–Iberian Coast, ABI; Macaronesia, AMA) with data from 1800 to 2021. An overall 574 were identified an alien, cryptogenic, crypto-expanding, or debatable status, mostly invertebrates (~65%) primary producers (~22%). Of 412 alien species, 80.51% reported ABI, 67.82% WMED, 66.67% AMA. Cryptogenic are more abundant WMED (25.25%), compared AMA (19.77%) ABI (18.46%). harbors established (62.56%) than (45.2%) (43.56%), contrary casual records (AMA 31.64%, 23.76%, 13.85%). Invasive (14.36%) WMED. ‘transport-stowaway’ pathway accounted 142 (79.33%), 123 (67.58%), 169 (85.21%) AMA, respectively. second most common was ‘transport-contaminant’ related mariculture (~10% total), prevalently 42 (23.08%). Canary Islands stand out introduced through oil platforms throughout world. ‘Unaided’ a relevant secondary into particularly Lessepsian progressing westwards.

Abstract A literature review was conducted to investigate marine global and local extinctions their drivers; the followed PRISMA-EcoEvo guidelines. The data extracted enhanced with status assessments from IUCN Red List. We recorded for 717 species, of which 18 were extinctions. Most these on very localized sub-ecoregion scales. taxonomic group most reported molluscs (31%), by cnidarians (22%), fish (17%) macroalgae (15%). dominant drivers extinction differed group. High mobility taxa driven extinct mainly overexploitation, whereas low pollution, climate change habitat destruction. in Temperate Northern Atlantic (41%) Central Indo-Pacific (30%). Overexploitation historically primary driver However, last three decades, other drivers, such as change, variability, have prevailed published literature. Half species not assessed List, 16% threatened categories. Global environment attributed invasive destruction, trophic cascades, pollution. derived low-confidence data. Inadequate monitoring may lead false reports or silent that are never reported. Improved conservation restoration actions urgently needed halt biodiversity loss.
