“…The authors found most of the ecological services (food provision, water purification, recreation and tourism) were negatively impacted by the presence of NIS. The results of a few macro-ecological studies [124,139] have revealed the presence of positive relationships between alien and native species richness in marine environments focusing attention on some large-scale features. These factors, not detectable by studies carried out on a single species or habitat, can contribute toward the development to a more complete understanding of the impacts of alien species from an ecosystem perspective [124,140,141].…”

“…These factors, not detectable by studies carried out on a single species or habitat, can contribute toward the development to a more complete understanding of the impacts of alien species from an ecosystem perspective [124,140,141]. Moreover, the general perception that NIS are a threat to biodiversity is true [142,143] but it should be considered that in most cases the time of investigation has not been long enough to clarify their real effects on the habitat composition and functioning [139,144]. On the one hand, the impact of NIS on biodiversity cannot be generalized because they cause different effects at several spatial and temporal scales [13,124,[145][146][147][148][149][150][151] being difficult to predict the fate of NIS in new habitat [152].…”

“…On the other hand, there is the possibility that some endangered species could also benefit from their transport towards different environments. In fact, considering that some invaders could survive better than endemic species in changing habitats that may compensate the decrease in the number of species caused by climate change and may act as 'reservoirs of diversity' [139,153]. According to Davis et al [154], the 'practical value of the native-versus-alien species dichotomy' in conservation is setting.…”

“…According to Davis et al [154], the 'practical value of the native-versus-alien species dichotomy' in conservation is setting. As suggested by Giangrande et al [139], therefore, it is essential to distinguish early NIS from naturalized species defining a temporal baseline that can be used for this purpose.…”

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 their invasiveness, 44% are casual, 11% have a taxonomic status unresolved, and 3% are included in the category ”cryptogenic”. The biodiversity CC NIS of the Mediterranean Sea has changed considerably in the last two decades and 27 out of 98 Mediterranean CC NIS are present in the Italian waters. Fifteen CC NIS, some equipped with high invasive potential, should be regarded as good candidates to become future immigrants of the Italian waters. Anticipatory NIS forecast based on biogeographical and ecological analyses may provide a useful tool for targeted management of the CC NIS issue and for the assessment of the second descriptor of Good Environmental Status. On the other hand, conservation and management of marine ecosystem should be based on the conservation of the essential environmental conditions for the functioning of these ecosystems instead of the contamination or eradication of alien species.

The sea walnut, Mnemiopsis leidyi, has invaded and expanded throughout the whole Mediterranean Sea basin. Large blooms were recorded also in the Venice Lagoon (Italy), an ecosystem rich with biodiversity which supports multiple services, including artisanal fishery production. To investigate M. leidyi impacts on lagoon artisanal fisheries, we combined fishers’ local ecological knowledge, fishery landing time series analysis, and field sampling. Firstly, we interviewed artisanal fishers to date the blooms of M. leidyi. Secondly, we analyzed long-term fishery landings records to detect whether changes in landings quantity and composition were related to the ctenophore invasion. Thirdly, we sampled catches of the lagoon fyke nets. This interdisciplinary approach overcame the weaknesses of single methodologies and allowed us to reconstruct the temporal phases of M. leidyi invasion in the Venice Lagoon. Moreover, our results indicate that the lagoon landings significantly declined with the blooms, paralleled by the increase of water temperature. Finally, we showed that the mechanical obstruction of the nets, caused by the massive ctenophore blooms, strongly impacts fishing activities. Our results are a first step in assessing the short and long-term impacts of this invasive species on lagoon ecosystems, including its socioeconomic consequences, whose better understanding is fundamental to inform mitigation and adaptation measures.

A first molecular insight into the invasive ctenophore Mnemiopsis leidyi in the northern Adriatic sea

Mnemiopsis leidyi A. Agassiz, 1865 is an invasive ctenophore that has spread to many areas of the Eurasian seas in recent decades and is one of the 100 most dangerous species in the world. This species was first observed in the northern Adriatic Sea in 2005 and then disappeared until 2016, when its first bloom was recorded. After that, it bloomed every summer in the area, causing severe damage to artisanal fisheries. Given the lack of genetic data for the northern Adriatic, here we compare the genetic diversity and phylogenetic relationships of M. leidyi populations sampled in 2016, 2018 and 2021 on the north-eastern coast of Italy with native populations and those introduced in other basins using two molecular markers: CytB and ITS. The CytB haplotype found in the samples from the northern Adriatic was identical to that found in the Gulf of Mexico and the Black Sea/Mediterranean. ITS analysis revealed 11 alleles, including 8 novel ones. The presence of a panmictic population in the northern Adriatic and the lower genetic variability compared to the native populations suggest that M. leidyi has been introduced into the Adriatic more than once and the species recently expanded in this area.
