Climate change is causing an increase in the frequency and intensity of marine heatwaves (MHWs) mass mortality events (MMEs) organisms are one their main ecological impacts. Here, we show that during 2015-2019 period, Mediterranean Sea has experienced exceptional thermal conditions resulting onset five consecutive years widespread MMEs across basin. These affected thousands kilometers coastline from surface to 45 m, a range habitats taxa (50 8 phyla). Significant relationships were found...

Bioconstructions such as coralligenous outcrops and maërl beds are typical Mediterranean underwater seascapes. Fine-scale knowledge on the distribution of these sensitive habitats is crucial for their effective management conservation. In present study, a thorough review existing spatial datasets showing across Sea was undertaken, highlighting current gaps in knowledge. Predictive modelling then carried out, based environmental predictors, to produce first continuous maps two entire basin....
Climate change and biological invasions are rapidly reshuffling species distribution, restructuring the communities of many ecosystems worldwide. Tracking these transformations in marine environment is crucial, but our understanding climate effects invasive dynamics often hampered by practical challenge surveying large geographical areas. Here, we focus on Mediterranean Sea, a hot spot for to investigate recent spatiotemporal changes fish abundances distribution. To this end, accessed local...

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and neonative species in Mediterranean Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records make them open access scientific community.Through this effort, we collected harmonized dataset 12,649 records.It includes 247 taxa, which 217 are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
An updated inventory of alien marine fauna in coastal and offshore Tunisian waters is presented. Records were compiled from scientific ‘grey’ publications, presentations at meetings, theses presented fulfillment requirements towards MSc PhD degrees, websites personal observations. 136 species recorded waters, 60 records northern coasts, West Mediterranean 76 central southern Central Mediterranean. Nearly half the first sightings took place Gulf Gabès. The dominant taxa are Crustancean (24%),...
Macroalgal forests are one of the most productive and valuable marine ecosystems, but yet strongly exposed to fragmentation loss. Detailed large-scale information on their distribution is largely lacking, hindering conservation initiatives. In this study, a systematic effort combine spatial data Cystoseira C. Agardh canopies (Fucales, Phaeophyta) was carried out develop Habitat Suitability Model (HSM) at Mediterranean scale, providing critical tools improve site prioritization for...
The presence of the North American Marmorkrebs (Procambarus fallax f. virginalis) in European inland waters is entirely driven by ongoing propagule pressure from ornamental trade.Since 2003 at least 25 independent introduction events have been confirmed, which some eventually resulted established populations.This study links a maximum-entropy model that forecasts probability based on socio-economic predictors to an updated species distribution environmental order explore risk further...
The silver-cheeked toadfish ( Lagocephalus sceleratus , from the pufferfish family Tetraodontidae) and Pacific red lionfish Pterois miles Scorpaenidae) have recently invaded Mediterranean Sea. has spread throughout this entire sea with highest concentrations in eastern basin, while more recently, Eastern to Central Their effects on local biodiversity fisheries are cause for management concern. Here, a comprehensive review of predators these two species their native Indo-Pacific Western...
Abstract Connectivity between populations influences both their dynamics and the genetic structuring of species. In this study, we explored connectivity patterns a marine species with long‐distance dispersal, edible common sea urchin Paracentrotus lividus , focusing mainly on Adriatic–Ionian basins (Central Mediterranean). We applied multidisciplinary approach integrating population genomics, based 1,122 single nucleotide polymorphisms ( SNP s) obtained from 2b‐ RAD in 275 samples,...
The Atlantic crab Callinectes sapidus was recently recorded in Tunisia and presents an invasive behavior. This study aims to evaluate its socio-economic impacts on small-scale fisheries analyze variations chemical composition, fatty acids profile, nutritive value according sex edible tissues. Socio-economic surveys via face-to-face revealed a decline fishermen’s income from 15% even 70% (damages fishing nets catches). Muscles yield of ranged between 36.07±2.84% 42.83±6.53% respectively for...
This paper concerns records of species that have extended their distribution in the Mediterranean Sea. The finding rare brackish angiosperm Althenia filiformis island Cyprus is interesting since its insertion Red Data Book Flora suggested. following enriched flora or fauna lists relevant countries: red alga Sebdenia dichotoma (Greece), hydrachnid mite Pontarachna adriatica (Slovenia), and thalassinid Gebiacantha talismani (Turkey). Several alien were recorded new localities. record burrowing...
Connectivity between populations shapes the genetic structure of species being crucial for an effective management environmental resources. Genetic approaches can provide indirect measures connectivity, allowing identification genetically differentiated - unconnected populations. In this study, we applied a 2b-RAD approach based on hundreds polymorphic loci to first detailed insight into population genomics Mediterranean mussel Mytilus galloprovincialis in part its native geographical range....

Two specimens of African hind Cephalopholis taeniops (Valenciennes, 1828) are recorded for the first time in Mediterranean Sea, coastal area Gulf Syrte, Libya. This finding represents an additional case a tropical species fish West origin Sea.
Local Ecological Knowledge of 92 professional fishers from Tunisia and Libya was used to investigate on the occurrence establishment exotic Hemiramphus far Saurida undosquamis along southern Mediterranean coasts. According fisherman’s knowledge, H. S. appeared in Libya, 1980 1989 respectively. In these species were observed afterwards, 2004 2007. Currently both result be well distributed established, entire surveyed area, Tubrouk (eastern Libya) Tabarka (western Tunisia). A statistical...
A single Blue swimming crab Portunus segnis was captured on November 5 th 2022 close to the harbor of Ancona, off central Adriatic coast (Italy) by artisanal fishers.Taxonomic comparisons were performed with collection materials, which also included two unreported specimens species from Ionian Calabria, Italy.The large distance between record P. and its invasion front, reinforces hypothesis that human-mediated translocations contribute secondary dispersal or introduction this invasive in...
The spotfin flyingfish Cheilopogon furcatus is recorded for the first time in Mediterranean Sea, near Zarzis, Gulf of Gabès, southern Tunisia. This record probably due to migration from eastern Atlantic through Strait Gibraltar.
In this study, we report outbreak of viral nervous necrosis (VNN) in wild Epinephelus species, which are an endangered fish group, different Tunisian coastal areas 2012. Seven E. marginatus and costae caught at dead or moribund condition were investigated. Betanodavirus was detected the brain retinal tissues all by RT-PCR high infective titers (106.0-8.8 TCID50/g) five seven fish. Sequence phylogenic analyses genes revealed that viruses belonged to RGNNV genotype closely related some...
The latest report from the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) expresses concern over global proliferation of non-native species (NIS) driven by increasing temperatures. In 2023, invasive blue crab Portunus segnis in Mediterranean experienced a significant range expansion due to warmer waters northern western regions. Recognizing thermal tolerance as crucial for conservation, this study, using model, emphasized importance considering metabolic...
