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.

International Journal of Data Science and Analytics, Год журнала: 2024, Номер unknown

Опубликована: Март 7, 2024

Abstract Integrated Environmental Assessment systems and ecosystem models study the links between anthropogenic climatic pressures on marine ecosystems help understand how to manage effects of unsustainable exploitation ocean resources. However, these have long implementation times, data model interoperability issues require heterogeneous competencies. Therefore, they would benefit from simplification, automatisation, enhanced integrability underlying models. Artificial Intelligence can overcome several limitations by speeding up modelling crucial functional parts, e.g. estimating environmental conditions fostering a species’ persistence proliferation in an area (the ecological niche) and, consequently, its geographical distribution. This paper presents full-automatic workflow estimate distributions through statistical machine learning It embeds four niche with complementary approaches, i.e. Neural Networks, Maximum Entropy, Support Vector Machines, AquaMaps. automatically estimates optimal parametrisations decision thresholds distinguish suitable- unsuitable-habitat locations combines within one ensemble model. Finally, it produce species richness map (biodiversity index). The software is open-source, Open Science compliant, available as Web Processing Service-standardised cloud computing service that enhances efficiency, integrability, cross-domain reusability, experimental reproduction repetition. We first assess stability sensitivity then demonstrate effectiveness producing biodiversity index for Mediterranean based $$\sim $$ ∼ 1500 data. Moreover, we predict spread invasive Siganus rivulatus current future overlap native Sarpa salpa under different climate change scenarios.

In marine environment, non-indigenous species (NIS) can alter natural habitats and cause biodiversity loss with important consequences for ecosystems socio-economic activities. With more than 1000 NIS introduced over the last century, Mediterranean Sea is one of most threatened regions worldwide, requiring an early identification newly entered alien a proper environmental management. Here, we carried out environmental-DNA (eDNA) metabarcoding analyses, using multiple molecular markers (i.e., 18S rRNA, COI, rbcL) different genetic databases NCBI, PR2, SILVA, MIDORI2, MGZDB, BOLD), on seawater sediment samples collected seasonal basis in three ports located North Adriatic, Ionian Tyrrhenian to identify species, particularly NIS. The use multi-marker eDNA allowed higher number compared morphological analyses (1484 vs. 752 species), minor portion shared by both approaches. Overall, only 4 were consistently identified approaches, whereas 27 17 exclusively detected classical taxonomic respectively. also identifying signatures 5 never reported Italian waters. We conclude that represent highly sensitive tool NIS, but comprehensive census requires combination

Human societal development has caused rapid degradation of freshwater ecosystems, resulting in significant biodiversity decline globally. The conservation aquatic particularly the management urban areas, become an increasingly issue for ensuring sustainability these ecosystems. restoration degraded ecosystems relies on a comprehensive understanding interactions between biological communities and multiple stressors derived from human activities. Environmental DNA (eDNA)-based methods have emerged as effective tools dissecting complex community-environment interactions. Nevertheless, potential causes technical disparities conclusions drawn conventional sampling versus eDNA-based remain inadequately evaluated. In this study, we conducted survey plankton along environmental gradient North Canal River Northern China to assess consequences any net tow eDNA metabarcoding-based analysis plankton-environment Our findings demonstrated that eDNA-metabarcoding was characterizing both geographical distribution. Both exhibited general consistency elucidating community structure identifying key factors influencing distribution zooplankton phytoplankton. As explored lower taxonomic ranks, found inconsistent patterns at certain levels (e.g., phylum or order) within some taxa Bacillariophyta Rotifera), even substantial variability several groups Euglenozoa Apicomplexa). varied prevalence persistence eDNA, ecological characteristics diverse plankton, efficiency likely contributed observed disparities. Given its higher recovery capacity, efficiency, convenience, capability identify influential driving biodiversity, metabarcoding is recommended studying interactions, studies involving large number samples extended scales.

Abstract Coastal areas host a major part of marine biodiversity but are seriously threatened by ever‐increasing human pressures. Transforming natural coastlines into urban seascapes through habitat artificialization may result in loss and key ecosystem functions. Yet, the extent to which seaports differ from nearby habitats reserves across whole Tree Life is still unknown. This study aimed assess level α β‐diversity between reserves, whether these patterns conserved taxa evolutionary lineages. For that, we used environmental DNA (eDNA) metabarcoding survey six on French Mediterranean coast four strictly no‐take nearby. By targeting different groups—prokaryotes, eukaryotes, metazoans fish—with appropriate markers, provide holistic view contrasted habitats. In absence comprehensive reference databases, bioinformatic pipelines gather similar sequences molecular operational taxonomic units (MOTUs). contrast our expectations, obtained no difference MOTU richness (α‐diversity) except for prokaryotes fishes with higher diversity than seaports. However, observed marked dissimilarity (β‐diversity) all taxa. Surprisingly, this signature was preserved Life, up order. reveals that share few lineages along urbanized coasts suggests differences terms functioning both

Abstract Bycatch and discards, representing unwanted catches, undermine sustainable fisheries hinder the conservation of vulnerable endangered species. To effectively monitor bycatch enhance effectiveness management measures while promoting fishing practices, reliable data is essential. Here, we explore use Nanopore metabarcoding to analyze catch composition in demersal bottom fisheries. We collected eDNA samples directly from an onboard holding tank ( water ) for 10 hauls a vessel operating Skagerrak (North‐East Atlantic). The approach involved sequencing combination long (~2 kb) short (~170–313 bp) mitochondrial amplicons was validated by analyzing fishery‐related mock community sample haul replicates. Overall, detection rate accuracy 95% landed species, replicates obtained same showed consistent results, validating robustness this approach. all caught species observed on board (including non‐landed fraction) 81%. Undetected were always limited low abundance, but may also be attributed problems with identifying closely related due impact errors diagnostic variation genetic regions used. In future, such biases reduced using additional markers increase discrimination power applying newly available technological advantages flow cell chemistry improve accuracy. conclusion, study demonstrates estimating trawl fisheries, including catches non‐commercial threatened without disrupting activities. Incorporating analysis therefore help facilitate effective monitoring, leading better‐informed management, biodiversity efforts, implementation relevant legislation as EU landing obligation.
