This paper is part of a series of studies aimed at understanding the potential exploitation of the biomass of the polychaete worm Sabella spallanzanii (Gmelin, 1791), which is obtained as a by-product of an innovative Integrated Multi-Trophic Aquaculture (IMTA) system. IMTA systems are designed according to an ecosystem approach with the aim to red...

Biodiversity is a broad concept that encompasses the diversity of nature, from the genetic to the habitat scale, and ensures the proper functioning of ecosystems. The Mediterranean Sea, one of the world's most biodiverse basins, faces major threats, such as overexploitation of resources and climate change. Here we provide the first multi-taxa inven...

The pressure of the anthropic activities (pollution, species introduction, overfishing, coastal development) on the marine ecosystem has intensified in the past decades with effects that include global warming and ocean acidification. Previous detailed studies in the Mediterranean Sea showed that small changes in sea temperature can influence the s...

The aims of the present paper were to review the knowledge about the Mediterranean non-indigenous species of the taxa Cnidaria and Ctenophora (CC NIS), to screen the risk of 98 species for their potential invasiveness in the Mediterranean Sea and their approach to the Italian waters. Of these, 38% are well established in the basin, 4% are known for...

Effects of ocean acidification (OA) on the plant phenology and colonization/settlement pattern of the hydrozoan epibiont community of the leaves of the seagrass Posidonia oceanica have been studied at volcanic CO2 vents off Ischia (Italy). The study was conducted in shallow Posidonia stands (2.5–3.5 m depth), in three stations on the north and thre...

The pressure of anthropogenic activities on the marine ecosystem has increased in recent decades. Previous studies in the Mediterranean Sea have shown that small changes in temperature can influence the phenology of species and the diversity of marine communities. Complete species inventories are very rare and the assessment of biodiversity is ofte...

In recent decades, the high introduction rate of alien species (AS) has been mainly due to the increasingly widespread human movements, which often compromise natural barriers, facilitating the invasion of new geographic areas and environments. Being completely new in the recipient habitat, alien invasive species can often have strongly negative im...

The rise in water temperature in the Mediterranean Sea, and associated migrations of temperate marine biota, are occurring in the context of a global warming causing an expansion of the tropical jellyfish range, exacerbating jellyfish outbreaks linked to coastal development, nutrient loading, and overfishing. The gelatinous component of plankton is...

Water temperature directly affects life cycles, reproductive periods, and metabolism of organisms living the oceans, especially in the surface zones. Due to the ocean warming, changes in water stratification and primary productivity are affecting trophic chains in sensitive world areas, such as the Mediterranean Sea. Benthic and pelagic cnidarians...

Biological systematics provides taxonomic information and expertise for biogeography and biological invasion research and management. However, the systematic classification of most taxa, including some alien and invasive species, relies only on morphology. This applies for example to Sertularella tongensis Stechow, 1919, an alien hydrozoan recently...

The re-examination of marine alien species or Non-indigenous species (NIS) reported in Italian Seas by December 2018, is here provided, particularly focusing on establishment success, year of first record, origin, potential invasiveness, and likely pathways. Furthermore, their distribution is assessed according to marine subregions outlined by the...

The EU regulation on the prevention and management of the introduction and spread of invasive alien species (IAS) is based on the core concept of "IAS of EU concern": species to be targeted for action. Besides the existing, and continuously being updated, European list, Italy is developing its own national list. Here we describe the process of deve...

The decline of morphologically based taxonomy is mainly linked to increasing species redundancy, which probably contributed to a worldwide disinterest in taxonomy, and to a reduction of funding for systematic biology and for expertise training. The present trend in the study of biodiversity is integrated taxonomy, which merges morphological and mol...

Recently, genetic approaches have revealed a surprising bacterial world as well as a growing knowledge of the enormous distribution of animal–bacterial interactions. In the present study, the diversity of the microorganisms associated to the hydroid Aglaophenia octodonta was studied with epifluorescence, optical, and scanning electron microscopy. S...

The project “Biodiversity MARE Tricase” aims to research and promote coastal and marine biodiversity at the MARE Outpost (Avamposto MARE), a marine station established in Tricase (Lecce, Italy) in 2015. From March 2016 to September 2017, the first biodiversity inventory of the Tricase coastal area (Ionian Sea) was realized with the aid of citizen s...

Molecular phylogenetics provides objective references for zoological systematics which sometimes are inconsistent with morphological data. This particularly counts for some primitive phyla such as Cnidaria. The marine hydrozoan Symplectoscyphus turgidus (Sertularellidae) is a recent questionable case reported to occupy an unexpected phylogenetic po...

Biodiversity is the result of billions years of evolution and it is the most precious good we have on earth. Biodiversity is fundamental to the functioning of ecosystems and it provides us many goods and services. Due to an unsustainable mode of development, we risk to lose this immense heritage.

The morphological character of the hydrocladium and gonotheca origin from within the hydrothecal cavity has rarely been applied for generic diagnoses in hydrozoans. Its taxonomic value has been controversial for more than a century. The genus Fraseroscyphus Boero and Bouillon, 1993 (Hydrozoa: Sertulariidae) is a relatively recently debated case and...

The Hydrozoa, an inconspicuous taxon of invertebrates, contributes significantly to the bulk of biodiversity but, usually, is noticed only by specialised taxonomists. The taxon Hydrozoa of the phylum Cnidaria comprises about 3800 nominal species, about which knowledge has greatly progressed in recent decades due to the scientific research of some s...

In spite of considerable research effort on the “immortal jellyfish” Turritopsis dohrnii (Weismann, 1883), a comprehensive account including the ontogenetic stages throughout its normal life cycle is still missing. Here, we report the development of the medusa morph, with description of four consecutive stages distinguished by the morphology of the...

The present note reports a new record of Rosalinda incrustans (Cnidaria: Hydrozoa) since its last reliable record in the Mediterranean Sea in 1958. Several colonies were recorded on the spider crab Anamathia rissoana off the Balearic Islands. The taxonomic history of R. incrustans, considered a putatively extinct species in a recent paper, is revie...

1. Spread of alien species (AS) is a serious threat to marine habitats and analysis of principal descriptors of their occurrence is pivotal to set reliable conservation strategies. 2. In order to assess the susceptibility of marine habitats to biological invasions, a dataset was gathered of the occurrence of 3899 species from 29 phyla, taken from 9...

The marine benthic fauna in Arctic shallow-water is reported to be a relatively young assemblage by species of either Pacific or Atlantic affinity. Whether current deep-sea Pacific species are included in the affinity or not is unknown. Combining morphological comparisons and genetic analyses, a new deep-sea hydroid to science, Sertularia xuelongi...

Cassiopea polyps that appeared in culture vessels of Turritopsis sp. polyps at the Seto Marine Biological Laboratory, Kyoto University in 2014 were experimentally amputated their stalks from the calyxes. On the cutting plane, planuloid buds were exclusively produced and stalks were never regenerated. Planuloids became polyps but some of them were n...

The majority of Hydrozoa is represented by not readily noticeable, small species. In recent decades, however, taxonomic knowledge of the group has increased worldwide, with a significant number of investigations focused on the Mediterranean Sea. Over more than two decades, 115 species of hydrozoans were recorded from coastal waters along nearly 300...

Porpita porpita widely occurs in the Atlantic and Indo-Pacific Oceans, and the Mediterranean Sea. In spite of its presence in the north-western Indian Ocean with records from the eastern Arabian Sea (Indian coast), its distribution in the North Arabian Sea, at the Pakistan coast has been found lacking in the literature. The present report deals wit...

Aequorea pensilis was recorded for the first time in massive quantities on 17 August 2013 at Damb, Sonmiani; however, only a few stranded specimens were collected from Clifton on 2 December 2012. Both these localities are on the Pakistan coast. These findings suggest that, A. pensilis has been established in this region. This report also provides t...

In the Mediterranean Sea, as well as in other parts of the word, intense bottom trawling threatens deep and mesophotic assemblages, compromising mainly the survivorship of erect organisms and of the habitat complexity they shape. Protection of species able to affect their habitats, by increasing spatial complexity and enhancing interspecific intera...

The Mediterranean hydrozoan fauna (Siphonophora excluded) comprises 400 species; most (68%) occur in the Atlantic Ocean, 20% are endemic to the Mediterranean, 8% are of Indo-Pacific origin, and 4% are non-classifiable. There are 69 nonindigenous (NIS) species in the basin: 44% of these are casual (recorded just one or very few times), 28% establish...
