“…Successfully invading thermophilic species are expected to take advantage of increased average temperatures (Dulčić and Grbec, 2000; UNEP -MAP -RAC/SPA, 2008; Dulčić et al, 2010Dulčić et al, , 2011Brotz and Pauly, 2012;Zenetos et al, 2012;Pecarevič et al, 2013) but they also need to either find or make trophic niche space, such as by outcompeting native species (e.g., Pranovi et al, 2003). Meanwhile, some local native species might be negatively affected by higher temperatures, but may be able to exploit new trophic opportunities as a trade-off.…”

Changing marine temperatures modify the distributional ranges of natural populations, but the success of invasion of new areas depends on local physical and ecological conditions. We explore the invasion by thermophilic species and their ecosystem effects by simulating a sea surface temperature (SST) increase using a trophodynamic model for the northern Adriatic Sea (NAS), in which thermal and trophic niches are explicitly represented for each thermophilic non-indigenous species (NIS) and native species. The NAS acts as a cul-de-sac for local species, preventing a further poleward migration as a response to temperature rise. In this situation, model results showed that effects of warming and invasion produced complex, non-linear changes on biomasses but never resulted in a complete overturn of a group of native species and/or a bloom of invasive ones. Despite this, the diversity index stabilizes at increased values after simulating invasion, possibly indicating that in such enclosed systems the establishment of invasive species could represent an enrichment in ecosystem structure. In addition, the absence of complete species substitution clearly showed the contribution of resident species toward increasing the resilience, i.e., the capability of the system to cope with invasion without changing substantially. Contrasting scenarios highlighted that changes in ecosystem primary production and species adaptation had secondary effects in ecosystem structure, while results for scenarios with different exploitation levels indicated that fishing can destabilize community structure in these change contexts, e.g., reducing community resilience. The results confirmed the importance of an ecological niche approach to analyze possible effects of invasion and highlighted the complexity of dynamics linked to temperature-driven species invasion', in terms of both the predicted strength of impacts and the direction of biomass change.

“…There are cases of other Lessepsian migrant species detected for the first time in the Gulf of Trieste, such as Epinephelus coioides (Parenti and Bressi, ) and Terapon theraps (Lipej et al., ). A second record of this species in the Adriatic Sea was observed in its southern part (Dulčić et al., ). Subsequent records, reported in this paper, were also from the southern part; however, this time, juvenile specimens were caught.…”

“…Approximately 80 species of Lessepsian fish migrants have been reported from the Mediterranean Sea (Golani et al., ); of these, 13 were recently reported from the Adriatic Sea (Dulčić and Dragičević, ). The latter include bluespotted cornetfish Fistularia commersonii Rüppell, 1838 (Dulčić et al., ; Joksimović et al., ) and dusky spinefoot Siganus luridus (Rüppell, 1829) (Poloniato et al., ; Dulčić et al., ). First record of the bluespotted cornetfish in the Mediterranean dates back to 2000 from the coast of Israel (Golani, ).…”

“…Due to its rapid invasion throughout the Mediterranean, including its western part, bluespotted cornetfish was nicknamed the ‘Lessepsian sprinter’ (Karachle et al., ). The first record of the dusky spinefoot in the Mediterranean dates back to 1955 from the coast of Israel (Ben‐Tuvia, ) and shortly after its discovery, it became very common in most coastal areas of the Mediterranean (see in Dulčić et al., ).…”

“…In conclusion, in spite of the fact that northward shifts of thermophilic species are largely demonstrated in the Adriatic Sea (Dulčić & Grbec, ; Dulčić et al ., , ), their presence in the lagoon has not been detected, which is possibly a sign of good resilience of the assemblage. A clear decreasing trend of both cold and temperate species, however, has been recorded, and a possible synergic effect of the increasing water temperature detected.…”

Within the context of global warming, the western coast of the northern Adriatic Sea can be regarded as an extremely vulnerable area. Owing to the local geographic features, this area has been described as the Venetian lacuna, where Mediterranean Sea climatic conditions are replaced by Atlantic Ocean ones, supporting the presence of glacial relicts, such as sprat Sprattus sprattus, flounder Platichthys flesus and brown shrimp Crangon crangon. Nektonic assemblage therefore represents a good candidate in terms of an early proxy for thermal regime alterations. It represents a dynamic component of the lagoon ecosystem, changing in space and time, actively moving through the entire system, and dynamically exchanging with the open sea. Here, the first signals of the change have been already detected, such as the presence of alien thermophilic species. Within this context, since the beginning of the century, sampling of the nektonic assemblage has been carried out, integrating them with landings data from the fish market. Vulnerabilities to thermal regime changes have been tested by (1) categorizing species according to the mean distribution area in terms of latitudinal range (over 45°, 30°-45° and below 30°), and (2) analysing both spatial and temporal variations within fishing grounds. Results indicated a high potential vulnerability of the artisanal fishery to climate change, as the commercial catch is entirely composed of species from cold (>45° N) and temperate (between 45° and 30° N) latitudes. At present no alien thermophilic species have been recorded within the lagoon, which is possibly a sign of good resilience of the assemblage. Finally, abundance of species from cold latitudes has decreased during the past decade. All of this has been discussed in the context of the mean annual temperature trend.
