Behaviour is predicted to be a primary determinant of the success of the invasion process during the early phases of colonization. Comparing invaders with sympatric native species may provide a good approach to unravel behavioural traits involved in an invasion process. In this study, we carried out an experimental simulation of the introduction an...

Cephalopod fisheries are increasing, but little is known about the cryptic diversity of some key commercial species. Recent studies have shown that cryptic speciation is common in cephalopods, including several oceanic squids formerly considered ‘cosmopolitan species.’ Further efforts are needed to investigate the cryptic diversity of commercial sp...

Understanding the genomic underpinnings of thermal adaptation is a hot topic in eco-evolutionary studies of parasites. Marine heteroxenous parasites have complex life cycles encompassing a free-living larval stage, an ectothermic intermediate host and a homeothermic definitive host, thus representing compelling systems for the study of thermal adap...

Syngnathids are considered flagship species of estuarine and coastal environments. However, most of the Mediterranean species are still classified as data-deficient (DD) at a global level according to the IUCN Red List of Threatened Species. In central Italy, several areas host potentially suitable habitats for syngnathids but have not been previou...

Biotic conflict can create evolutionary competition across species in the quest to maintain vital populations. In some cases, this process is driven by conflict among members of the same species, an important selective force in high-density non-indigenous populations. By killing and feeding on their intraspecific competitors, cannibals enhance thei...

Behaviour is predicted to be a primary determinant of the success of the invasion process during the early phases of colonization. Comparing sympatric invaders and native species may provide a good approach to unravel behavioural traits involved in an invasion process. In this study, we carried out an experimental simulation of the introduction and...

Larval settlement is a critical step for sessile benthic species such as corals, whose ability to thrive on diverse natural and anthropogenic substrates may lead to a competitive advantage in the colonization of new environments with respect to a narrow tolerance for a specific kind of substratum. Plastic debris, widespread in marine waters, provid...

Coastal environments can be influenced by water body masses with particular physical, chemical, and biological properties that create favourable conditions for the development of unique planktonic communities. In this study, we investigated a continental shelf front at Ponza Island (Tyrrhenian Sea) and discussed its diversity and complexity in rela...

Italy, at the center of the Mediterranean Sea, hosts a high diversity of fishes, but to a certain extent, this richness remains hidden or poorly known because of rare, cryptic or recently introduced species, that are hardly to detect with the traditional sampling approaches. In this study, we gained complementary knowledge, engaging Italian sea use...

The monitoring of plastic pollution through marine biota is a difficult task, which is receiving increasing attention nowadays. A selection of appropriate bioindicator species for plastic ingestion has been proposed, mostly covering benthic filter-feeding organisms or large marine vertebrates. However, monitoring programs involving a broad range of...

This paper is a collection of novel distributional records of 20 species belonging to 8 phyla (Chlorophyta, Rhodophyta, Cni-daria, Ctenophora, Annelida, Mollusca, Arthropoda and Chordata) from 11 Mediterranean countries, namely, Spain: an additional record of the Canary dentex Dentex canariensis is reported from Spain (Valencia), this is the northe...

ABSTRACT The biomonitoring of marine debris is a growing research field, which can provide useful information about sources and distribution of plastics, but also about the overall health of marine environments. Common sentinel species for plastic pollution mostly cover benthic filter-feeding organisms or endangered marine vertebrates, but monitori...

The Collective Article on “New Mediterranean Biodiversity Records” offers the means to publish biodiversity records in the Mediterranean Sea. The current article presents new biodiversity data information on 18 taxa (14 alien, 3 native and 1 cryptogenic species) belonging to 5 Phyla that are reported for 11 different countries listed according to t...

The precise number of Okenia taxa inhabiting the Mediterranean Sea, as well as their general taxonomy, varies according to different specialists. So far, eight valid species have been reported from the area: Okenia aspersa (Alder & Hancock, 1845), Okenia cupella (Vogel & Schultz, 1970), Okenia elegans (Leuckart, 1828), Okenia hispanica Valdés & Ort...

Results of the AlienFish project-monitoring and study of rare and non-indigenous fish species in Italian waters-collected through citizen science in 2018 are here reported. Overall, 36 observations of 21 fish species belonging to 17 families were provided from the central and southern sectors of Italian seas. Our findings highlight the effectivenes...

In the present article, new records are given for 15 species (4 native and 9 alien and 2 cryptogenic), belonging to 6 Phyla (i.e. Chlorophyta, Ctenophora, Cnidaria, Mollusca, Arthropoda, and Chordata), from 10 Mediterranean countries: Morocco: the finding of the crab Callinectes sapidus represents the westernmost one of the species in the Mediterra...

Invertebrates represent the most plentiful component of marine biodiversity. To date, only few species have been documented for marine litter intake. Here, we report for the first time the presence of macroplastic debris in a jellyfish species. Such novel target to plastic pollution highlights an under studied vector of marine litter along marine t...

The “New Mediterranean Biodiversity Records” series includes new records of marine species found in the Mediterranean basin and/or information on the spatial distribution of already established species of particular interest. The current article presents information on 21 marine taxa classified per country according to their geographic position in...

The identification of foraging hotspots able to support the co-existence of multiple top predators provides a potential approach to addressing protection measures for marine ecosystems. In this study, we conducted visual surveys in the central Tyrrhenian Sea to determine areas with simultaneous presence of bottlenose dolphins, four species of seabi...

The bottlenose dolphin (Tursiops truncatus) is one of the Mediterranean cetaceans listed in the Annex II of Habitat Directive for which the designation of Special Areas of Conservation (SACs) is required. Bottlenose dolphins occur regularly in most coastal waters of the basin and around many of the region’s offshore islands and archipelagos. Within...

The bivalve family Ostreidae has a worldwide distribution and includes species of high economic importance. Phylogenetics and systematic of oysters based on morphology have proved difficult because of their high phenotypic plasticity. In this study we explore the phylogenetic information of the DNA sequence and secondary structure of the nuclear, f...

We hereby provide new distributional data for alien and possible alien molluscs from the Italian seas, together with a brief review of their known Italian distribution and updated distributional maps. In particular, Haminoea cyanomarginata is confirmed for the Calabrian shores of the Messina Strait area and is first reported from the eastern and we...

Amphibians have life cycle strictly linked to water systems: in their larval stages amphibians live in water, whereas in their adulthood they have to return to water for reproduction. This prolonged connection with water systems makes amphibians good model organisms for investigating the presence and the effects of environmental stressors in waters...

The evolution of the molluscan biota in Sabaudia Lake (Italy, central Tyrrhenian Sea) in the last century is hereby traced on the basis of bibliography, museum type materials, and field samplings carried out from April 2009 to September 2011. Biological assessments revealed clearly distinct phases, elucidating the definitive shift of this human-ind...

The state of knowledge of the alien marine Mollusca in Italy is reviewed and updated. Littorina saxatilis (Olivi, 1792), Polycera hedgpethi Er. Marcus, 1964 and Haminoea japonica Pilsbry, 1895 are here considered as established on the basis of published and unpublished data, and recent records of the latter considerably expand its known Mediterrane...
