Marine protected areas' positive effect on fish biomass persists across the steep climatic gradient of the Mediterranean Sea

Ori Frid, Shahar Malamud, Antonio Di Franco, Paolo Guidetti, more

Journal of Applied Ecology > 60 > 4 > 638 - 649

The positive effect of fully protected marine protected areas (MPAs) on marine biodiversity, and specifically on fishes, has been widely documented. In contrast, the potential of MPAs to mitigate the impact of adverse climatic conditions has seldom been investigated. Here, we assessed the effectiveness of MPAs, quantified as increasing fish biomass, across wide geographic and environmental gradients...

Spatio‐temporal dynamics of exotic fish species in the Mediterranean Sea: Over a century of invasion reconstructed

Ernesto Azzurro, Sonia Smeraldo, Manuela D'Amen

Global Change Biology > 28 > 21 > 6268 - 6279

With over a thousand of introduced species, the Mediterranean is the most heavily invaded marine region in the world. Yet, the spatio‐temporal dynamics of this bioinvasion has never been analysed. Examination of a comprehensive dataset of 4015 georeferenced observations, extracted from the scientific literature, allowed (i) reconstructing the invasion and the introduction and post‐introduction dynamics...

Marine heatwaves drive recurrent mass mortalities in the Mediterranean Sea

Joaquim Garrabou, Daniel Gómez‐Gras, Alba Medrano, Carlo Cerrano, more

Global Change Biology > 28 > 19 > 5708 - 5725

Climate change is causing an increase in the frequency and intensity of marine heatwaves (MHWs) and mass mortality events (MMEs) of marine organisms are one of their main ecological impacts. Here, we show that during the 2015–2019 period, the Mediterranean Sea has experienced exceptional thermal conditions resulting in the onset of five consecutive years of widespread MMEs across the basin. These...

Mapping small‐scale fisheries through a coordinated participatory strategy

Fabio Grati, Ernesto Azzurro, Martina Scanu, Anna Nora Tassetti, more

Fish and Fisheries > 23 > 4 > 773 - 785

The knowledge of small‐scale fisheries (SSFs) is important to develop management policies and mitigate the competition for marine resources. However, spatially explicit information is often unavailable at the regional and subregional scale. We designed and tested a novel participatory approach to map the SSF fishing effort using the Mediterranean sea as a case study. We applied the approach in eight...

Integrating univariate niche dynamics in species distribution models: A step forward for marine research on biological invasions

Manuela D’Amen, Ernesto Azzurro

Journal of Biogeography > 47 > 3 > 686 - 697

Aim The development of approaches to predict the distribution and potential expansion of invasive species is still an open challenge. Here our goal is to improve the modelling procedure for marine invaders by coupling Species Distribution Models (SDMs) with an analysis of their univariate niche dynamics. In particular, we tested for the first time whether choosing model predictors among the stable...

Stefania Chiesa, Ernesto Azzurro, Giacomo Bernardi

Reviews in Fish Biology and Fisheries > 2019 > 29 > 4 > 837-859

We present a comprehensive review of the available global literature on the genetics and genomics of marine fish invasions. Overall this review provides data from 66 species belonging to 39 families, collected from 80 published studies on both WoS (Web of Science) and Scopus databases. We found that studies on alien fishes focused on specific geographic areas, mainly the Mediterranean region. Furthermore,...

A meta‐analysis of fish behavioural reaction to underwater human presence

Diogo S. M. Samia, Eduardo Bessa, Daniel T. Blumstein, José A. C. C. Nunes, more

Fish and Fisheries > 20 > 5 > 817 - 829

In an increasingly anthropic world, humans have profound impacts on the distribution and behaviour of marine fishes. The increased human presence has modified fishes’ antipredator behavioural responses, and consequently flight decisions, as a function of their changed perceptions of risk. Understanding how fish react to human presence can help identify the most vulnerable functional groups/species...

Climate change, biological invasions, and the shifting distribution of Mediterranean fishes: A large‐scale survey based on local ecological knowledge

Ernesto Azzurro, Valerio Sbragaglia, Jacopo Cerri, Michel Bariche, more

Global Change Biology > 25 > 8 > 2779 - 2792

Climate change and biological invasions are rapidly reshuffling species distribution, restructuring the biological communities of many ecosystems worldwide. Tracking these transformations in the marine environment is crucial, but our understanding of climate change effects and invasive species dynamics is often hampered by the practical challenge of surveying large geographical areas. Here, we focus...

Grouper fishery in the Northeastern Mediterranean: An assessment based on interviews on resource users

Sinan Mavruk, İsmet Saygu, Fethi Bengil, Vahit Alan, more

Marine Policy > 2018 > 87 > C > 141-148

Groupers are important components of coastal ecosystems as well as a valuable resource for fisheries. Their populations are known to be decreasing throughout the world primarily due to over-exploitation. However, even the basic data for an effective management strategy is lacking. Interviews of a representative sample of 113 fishers in Turkey in the northeastern Mediterranean were conducted with specific...

Jellyfish blooms perception in Mediterranean finfish aquaculture

Mar Bosch-Belmar, Ernesto Azzurro, Kristian Pulis, Giacomo Milisenda, more

Marine Policy > 2017 > 76 > C > 1-7

In recent years, negative impacts of jellyfish blooms (JB) on marine human activities have been increasingly reported. Aquaculture has been affected by jellyfish outbreaks, mostly documented through repeated episodes of farmed salmon mortalities in Northern Europe; however, the valuation of JB consequences on the aquaculture sector still remains poorly quantified. This study aims to provide the first...

Warming-related shifts in the distribution of two competing coastal wrasses

Marco Milazzo, Federico Quattrocchi, Ernesto Azzurro, Angelo Palmeri, more

Marine Environmental Research > 2016 > 120 > C > 55-67

Warming induces organisms to adapt or to move to track thermal optima, driving novel interspecific interactions or altering pre-existing ones. We investigated how rising temperatures can affect the distribution of two antagonist Mediterranean wrasses: the ‘warm-water’ Thalassoma pavo and the ‘cool-water’ Coris julis. Using field surveys and an extensive database of depth-related patterns of distribution...

Genomic signatures of rapid adaptive evolution in the bluespotted cornetfish, a Mediterranean Lessepsian invader

Giacomo Bernardi, Ernesto Azzurro, Daniel Golani, Michael Ryan Miller

Molecular Ecology > 25 > 14 > 3384 - 3396

Biological invasions are increasingly creating ecological and economical problems both on land and in aquatic environments. For over a century, the Mediterranean Sea has steadily been invaded by Indian Ocean/Red Sea species (called Lessepsian invaders) via the Suez Canal, with a current estimate of ~450 species. The bluespotted cornetfish, Fistularia commersonii, considered a ‘Lessepsian sprinter’,...

Phylogeography of the bluespotted cornetfish, Fistularia commersonii: a predictor of bioinvasion success?

Alexis M. Jackson, Kimberly Tenggardjaja, Gerardo Perez, Ernesto Azzurro, more

Marine Ecology > 36 > 4 > 887 - 896

Biological invasions result in huge ecological and economic impacts; therefore, a great amount of effort is dedicated to predicting the potential success of newly established or candidate bioinvaders. Thus far, over 90 species of fish have entered the Mediterranean Sea via the Suez canal, the so‐called Lessepsian bioinvaders. The bluespotted cornetfish, Fistularia commersonii, is remarkable in its...

Red Sea fishes in the Mediterranean Sea: a preliminary investigation of a biological invasion using DNA barcoding

Michel Bariche, Martha Torres, Colin Smith, Nancy Sayar, more

Journal of Biogeography > 42 > 12 > 2363 - 2373

AimMore than 90 marine fish species in the Mediterranean have been determined to be alien species of Red Sea origin to date and therefore it is important to prioritize research into cataloguing their distribution and impacts. The aims of this study were to establish a barcode library for alien Mediterranean fishes of probable Red Sea origin and to initiate analyses of their invasion dynamics. LocationMediterranean...

Niche shift can impair the ability to predict invasion risk in the marine realm: an illustration using Mediterranean fish invaders

Valeriano Parravicini, Ernesto Azzurro, Michel Kulbicki, Jonathan Belmaker, more

Ecology Letters > 18 > 3 > 246 - 253

Climatic niche conservatism, the tendency of species‐climate associations to remain unchanged across space and time, is pivotal for forecasting the spread of invasive species and biodiversity changes. Indeed, it represents one of the key assumptions underlying species distribution models (SDMs), the main tool currently available for predicting range shifts of species. However, to date, no comprehensive...

External morphology explains the success of biological invasions

Ernesto Azzurro, Victor M. Tuset, Antoni Lombarte, Francesc Maynou, more

Ecology Letters > 17 > 11 > 1455 - 1463

Biological invasions have become major players in the current biodiversity crisis, but realistic tools to predict which species will establish successful populations are still unavailable. Here we present a novel approach that requires only a morphometric characterisation of the species. Using fish invasions of the Mediterranean, we show that the abundance of non‐indigenous fishes correlates with...
