Abstract The disproportionately low presence of marine species in the list invasive alien (IAS) Union concern European (EU) Regulation 1143/2014 does not fully acknowledge threat they pose to EU environment. In this study, first EU‐scale Horizon Scanning (HS) focusing on was performed, aiming deliver a ranked that should be high priority for risk assessment (Article 5 IAS Regulation). Species absent from or with limited distribution waters were targeted. total, 363 initially screened HS by...
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,...
To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in Mediterranean Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records make them open access scientific community.Through this effort, we collected harmonized dataset 12,649 records.It includes 247 taxa, which 217 are Animalia, 25 Plantae 5 Chromista, from 23 countries surrounding Sea.Chordata most abundant taxonomic group, followed
Refined baseline inventories of non-indigenous species (NIS) are set per European Union Member State (MS), in the context Marine Strategy Framework Directive (MSFD). The based on initial assessment MSFD (2012) and updated data Alien Species Information Network, collaboration with NIS experts appointed by MSs. analysis revealed that a large number was not reported from assessments. Moreover, several initially listed currently considered as native Europe or were proven to be historical...
Management of invasive species, whether prevention, population reduction, or eradication, requires assessment the species' status and an probability success management options.Perceptions a permanence in environment lack thereof frequently drives how limited time, financial, personnel resources are allocated to such efforts.Language we use describe non-native largely defines these perceptions sets boundaries, real perceived, potential actions.Here discuss particular term -"established"when...
The number of alien species arriving within new regions has increased at unprecedented rates. Managing the pathways through which arrive and spread is important to reduce threat biological invasions. Harmonising information on across individual sectors user groups therefore critical underpin policy action. European Alien Species Information Network (EASIN) been developed easily facilitate open access data in Europe. Convention Biological Diversity (CBD) Pathway Classification framework...
Standardized tools are needed to identify and prioritize the most harmful non-native species (NNS). A plethora of assessment protocols have been developed evaluate current potential impacts species, but consistency among them has received limited attention. To estimate across impact protocols, 89 specialists in biological invasions used 11 screen 57 NNS (2614 assessments). We tested if scoring assessors, quantified as coefficient variation (CV), was dependent on characteristics protocol,...
The Convention on Biological Diversity (CBD) pathways classification framework used in the implementation of European Union’s (EU) Regulation 1143/2014 invasive alien species (IAS Regulation) has recently been adopted by Alien Species Information Network (EASIN), official information system supporting IAS Regulation. In current paper, result an alignment primary introduction all plants Europe included EASIN catalogue is presented, based CBD framework. total, 6,250 plant taxa (marine...
Invasive Alien Species (IAS) are a growing threat to Europe's biodiversity. The implementation of European Union Regulation on IAS can benefit from the involvement public in recording and management through Citizen Science (CS) initiatives. Aiming tackle issues related with use CS projects topics, dedicated workshop titled "Citizen Open Data: model for Europe" was organized by Joint Research Centre (JRC) Cooperation Technology (COST Association). Fifty key stakeholders all Europe, including...
There is no sign of saturation in accumulation alien species (AS) introductions worldwide, additionally the rate spread for some has also been shown to be increasing. However, challenges gathering information on AS are recognized. Recent developments citizen science (CS) provide an opportunity improve data flow and knowledge while ensuring effective high quality societal engagement with issue IAS (Invasive Alien Species). Advances technology, particularly on-line recording smartphone apps,...
Effective monitoring of non-indigenous seaweeds and combatting their effects relies on a solid confirmation the status respective species. We critically analysed presumed seaweed species reported from Mediterranean Sea, Northeast Atlantic Ocean Macaronesia, resulting in list 140 whose nature is undisputed. For an additional 87 it unclear if they are native or (cryptogenic species) identity requires (data deficient species). discuss factors underlying both taxonomic biogeographic...
This paper is a collection of novel distributional records 20 species belonging to 8 phyla (Chlorophyta, Rhodophyta, Cnidaria, Ctenophora, Annelida, Mollusca, Arthropoda and Chordata) from 11 Mediterranean countries, namely, Spain: an additional record the Canary dentex Dentex canariensis reported Spain (Valencia), this northernmost in Mediterranean; Algeria: first documented Caulerpa chemnitzia Algerian coast; France: Spotted sea hare Aplysia dactylomela eastern coast Corsica; Italy:...
Invasive alien species (IAS) induce changes to community structure and functions which lead a decline of endemic major irreversible the local physical habitat. The distribution impacts multiple freshwater IAS are not well known, they have been investigated simultaneously at catchment European scales. This study provides an assessment cumulative impact over catchments. occurrences were retrieved from Alien Species Information Network geospatial dataset updated with most recent records...
“New records of rare species in the Mediterranean Sea” (October 2021)
Human-induced biological introductions pose a major threat to global biodiversity, and this is especially frequent in the eastern Mediterranean region, which globally important biodiversity hotspot area of high conservation value. To predict at level introduced species region might become invasive under current projected climate conditions, 232 non-native aquatic organisms were screened using Aquatic Species Invasiveness Screening Kit. Based on receiver operative characteristic curve...
Abstract Citizen science (CS) expands the spatial and temporal scale of alien species records. As such, it has been recognized as a complementary tool in management large‐scale biodiversity conservation. The present study assessed contribution CS to recording marine fishes mollusks European waters by reviewing data available through Alien Species Information Network, portals, public databases, scientific literature. In total, 8,513 records were retrieved, following filtering procedure,...
Time lags in non-indigenous species (NIS) reporting can create uncertainty the analysis of NIS introduction rates, which lead to inadequate actions, prevention measures and their evaluation. The present study aims highlight time marine Mediterranean Sea, i.e.: that mediates from detection a new Sea until its publication. Our results revealed lag has been considerably decreased during last decades. There is also noticeable difference association with taxonomic group species. Fish have...
Shipping is the greatest pathway of non-indigenous species (NIS) introductions, and port areas are considered as alien hotspots. In this study, we analyzed data covering a 112-year period found that Saronikos Gulf in Greece, hosting one largest container terminals Europe, hotspot NIS introductions. To date, 89 have been recorded, which 8 characterized invasive. Most belong to taxonomic group Mollusca (33%), followed by Pisces (22%). For first time Mediterranean Sea, report presence...
