“…This species is widespread in the Mediterranean and in the Black Sea (Tena et al, 1991;Çinar et al, 2005;Dağli & Ergen, 2008;Simboura et al, 2008;Radashevsky & Selifonova, 2013;Bertasi, 2016). Bertasi (2016) reported this species as abundant in brackish lagoons of the Northern Adriatic Sea and retrieved it in samples collected in the 1990s, suggesting that its missed detection is due to misidentification with Polydora ciliata (Johnston, 1838). This is confirmed by Radashevsky & Selifonova (2013) for Levant and Black Seas.…”

Non-indigenous polychaetes along the coasts of Italy: a critical review

et al. 2020

Non-indigenous species (NIS) represent one of the most relevant threats to biodiversity, ecosystem functioning and human activities, and their occurrence and spread have been the subject of numerous works and revisions. However, the information available is rather confused for several taxa, including polychaetes, which are characterised by having a high number of cryptogenic and questionable species. This work aims at providing a revised checklist of alien polychaetes occurring along the coasts of Italy, based on the examination of newly collected and deposited material and on the critical analysis of published and gray literature, and whenever possible on the re-examination of historical material. Of the 86 polychaete species reported as NIS in Italian waters, 25 are confirmed as alien species, while 3 are cryptogenic, and 40 should be considered questionable. Finally, 18 species were excluded from non-indigenous species checklists, either because they are native, or because they represent misidentifications of other species. The high number of cryptogenic and questionable species points at the need of molecular studies and taxonomic revisions for the majority of polychaete taxa reported as NIS, in order to clarify their taxonomy, origin, introduction pathways and spreading patterns.

Polydora cornuta es considerada una especie oportunista con tolerancia a un amplio rango de salinidad y temperatura, al mismo tiempo que posee características que le permiten colonizar rápidamente áreas disturbadas tales como: maduración temprana y alta producción de larvas (Bertasi 2016, Bumber & Rocha 2016.

The aim of this thesis is to characterize the shallow gas deposits of the inner area of the Bahía Blanca estuary and to evaluate the effect of the gas-bearing sediments on the associated subtidal benthic communities. For this purpose, the distribution of shallow gas in the estuary was mapped through the analysis of highresolution seismic records. Based on this map, two study sites were selected (with gas and control) that only differed in the presence of gas in contact with the surface of the seabed. Acoustic methods were used to determine the stratigraphy and morphology of the site with gas and the adjacent area. In addition, the gas sediments were evaluated by means of the following analyses: grain size, organic matter content, X-rays and HPLC head space measurement. The benthic organisms of both sites were compared in terms of abundance, biomass, diversity, evenness, species richness, taxonomic and functional structure. The gas was found widely distributed in the estuary, both near and in contact with the surface of the seabed of the inner area of the Bahía Blanca estuary. It was evidenced in the form of acoustic turbidity and acoustic blanking. The seismo-stratigraphic column presented five seismic sequences of the late Pleistocene-Holocene. It was established that the gas origin is biogenic, being associated with a Middle Holocene deposit, from which it migrated until it was in contact with the surface of the seabed due to the permeability of the overlying strata. The gas in the surface of the seabed was evidenced in sonograms by means of the attenuation of the acoustic signal, which evidences a low cohesion Índice Dedicatoria…………………………………………………………………………………………………….I

“…The Adriatic Sea is the site of intense shellfish farming along the Italian coast, and finfish farming along the Croatian coast. To our knowledge, C. corona has not been recorded in any shellfish farming areas, such as those of the northern Adriatic that have experienced several introductions of alien species (Bertasi 2016;Munari et al 2016). Accordingly, we tend to exclude that aquaculture activities may have played a role in the spreading dynamics of C. corona to the Adriatic and Tyrrhenian seas.…”

The present study reports the spread of the cirratulids Chaetozone corona Berkeley & Berkeley, 1941 and Chaetozone carpenteri McIntosh, 1911 in the Western Central Adriatic Sea, off the coasts of Pescara (Italy). The two species were collected between 2014 and 2016 from soft bottom stations (at depths from 16.5 to 130 m) where the environment was more or less disturbed due to fishing activities. One specimen of C. corona was found also off the coast of Calafuria (Livorno, Italy), representing the first record of this species in the Tyrrhenian Sea. Chaetozone carpenteri could be a native species present in the Mediterranean for a long time but rarely recorded because of taxonomic confusion. Chaetozone corona was already known from the eastern Mediterranean Sea (except from the Adriatic Sea), where it is considered an established alien species. Our results extend the geographic range of these two cirratulid species, providing some information on their ecology and habitat preference. We also suggest a likely vector of spread of C. corona from the easternmost part of the Mediterranean towards the study area. The finding of reproducing specimens of C. corona and C. carpenteri supports the hypothesis that these two species have found a suitable habitat in the Western Central Adriatic Sea, and there will become well established. Although nothing suggests that C. corona would be invasive, it may, however, compete with native species. These findings also seem particularly relevant in order to improve the knowledge of Mediterranean biodiversity.
