“…Namely, during this study numerous taxa were not detected in port/ s which are endorsed in previously reported region of observation (Tables 5 and 6). For example, Scrippsiella lachrymosa was reported for several regions of the Adriatic, NW and mW (Rubino et al, 2000), SW (Rubino et al, 2002) and NE (Rubino et al, 2000;Rogelja et al, 2018). However, during this study it was observed only in ports of Trieste and Koper (NW region) and Bari (SW region), thus confirming that spreading taxa over entire region, including port areas, is not necessarily a process which is certain to occur.…”

The ability of microalgae to preserve viable in coastal sediments as resting forms provides a reservoir of biodiversity and a useful tool to determine species spreadings. This study represents the first port baseline survey on dinoflagellate cysts, investigated in nine Adriatic ports during a cross border project. 40 dinoflagellate taxa were detected. The assemblages resulted in all ports dominated by Lingulodinium polyedra and Alexandrium minutum/ affine/tamutum group. General separation to the western and eastern side of the Adriatic regarding cysts assemblage composition, partially abundance, was observed. Six taxa were detected as non-indigenous species for the Adriatic. Two taxa are included in the list of harmful aquatic organisms, indicating the potential threat of ballast waters in the Adriatic. Potential spreading of taxa by general circulation and ballast waters, intra-and extra-Adriatic was investigated. The entering in to force of the ballast waters management regulations should enhance prospects to minimize future harmful impacts.

“…In contrast, this diatom was observed in very low RA at St. 7, while it was completely absent at St. C1. According to Rogelja et al (2017), the increase of N. commutata in harbor sediments could be linked to contamination. However, even at the two most impacted sites of the port of Trieste, the microalgal community seemed to be affected by contamination to a much lesser extent than the one thriving in the surface FIGURE 6 | Prokaryotic C production (PCP) estimated at the seven stations within the Site of National Interest and at the reference site (St. C1).…”

This study is a rare example of "the ecosystem approach to management" that has been carried out for the purpose of providing practical support to decision-makers in managing a Site of National Interest (SIN) where activities such as fishing, aquaculture and swimming are restricted. Benthic ecosystem functioning was assessed to verify whether it would be possible to exclude the less contaminated part from the SIN and its legislative constraints. At five macrosites subjected to diversified industrialization and anthropization, we evaluated the structural characteristics of the sediments, both heterotrophic and phototrophic communities, and the main processes of production, transformation and consumption of organic matter at seven stations, plus a reference site. Along the north-eastern boundary of the bay, the port, shipbuilding and iron foundry areas, characterized by high levels of contaminants, low macrozoobenthic diversity, major organic contents (up to 51.1 mgC g −1 ) and higher numbers of hydrocarbon degrading bacteria (up to 5,464 MPN g dry −1 ), differed significantly (R ANOSIM = 0.463, p = 2.9%) from the other areas (stations). Oxygen consumption (−15.22 ± 1.59 mgC m −2 ) prevailed over primary production and the trophic state was net heterotrophic. In contrast, on the other side of the harbor (residential area/center bay), contamination levels were below the legal limits and both the microalgal and macrobenthic communities displayed higher biodiversity. Higher macrofaunal abundances (up to 753 ± 174.7 ind.m −2 ), primary production rates (up to 58.60 ± 8.41 mgC m −2 ) and exoenzymatic activities were estimated. nMDS and SIMPROF analyses performed on benthic communities significantly separated the most contaminated stations from the other ones. Overall, by applying this holistic approach, a better environmental situation was highlighted along the southern boundary of the bay and according to these results this part of the bay could be excluded from the SIN. However, further sampling is required along a finer sampling grid in the less contaminated side of the port in order to confirm these first results. Our work is one of the first case studies where such an ecosystem approach has been applied to a port area, in order to provide practical support to decision-makers involved in the spatial planning of harbor zones.

“…Benthic diatom communities of the Italian North Adriatic have been well studied on an artificial hard substrates at two stations, one in the Gulf of Trieste (Bartole et al, 1991-94) and the other in Venice lagoon (Tolomio & Andreoli, 1989;Tolomio et al, 1991), and in natural sediment samples from the Gulf of Trieste (Sdrigotti et al, 1999;Welker et al, 2002;Cibic et al, 2007;Franzo et al, 2014, Rogelja et al, 2018, the Venice lagoon (Tolomio et al, 1999(Tolomio et al, , 2002Facca et al, 2002a, b;Tolomio, 2004;Facca & Sfriso, 2007), the coast from Ancona to the Po delta (Totti, 2003), between Rimini and Pesaro (Franzo et al, 2015), and in the Lesina lagoon (Gambi et al, 2003). While an extensive literature on microphytobenthic species of the Italian seas exists (see Cibic & Facca, 2010 and references therein), only limited information is available on the composition of epilithic assemblages grown on either natural or artificial substrates in marine coastal waters of the eastern Middle and South Adriatic, e.g., epilithic diatoms from stones in the oligotrophic Neum Bay in Bosnia and Herzegovina (Hafner et al, 2018) and along Albanian coastal wetlands (Miho & Witkowski, 2005).…”

Epilithic diatom communities from areas of invasive Caulerpa species (Caulerpa taxifolia and Caulerpa cylindracea) in the Adriatic Sea, NE Mediterranean

Epilithic diatom community structures are compared among three locations of the eastern Adriatic Sea coast (Croatia), in the presence of two different invasive Caulerpa species, C. taxifolia and C. cylindracea, which have spread rapidly in the Mediterranean in the last decades. Forty samples were taken seasonally at three sites (island of Hvar, island of Mljet, and Dubrovnik) between November 2008 and October 2010. Light and electron microscopy examinations were used for qualitative analysis. Altogether 310 epilithic taxa belonging to 65 genera were identified. The highest number of these taxa belonged to Mastogloia (48) and Amphora (32), followed by Diploneis (24), Nitzschia (23), Navicula (22), and Cocconeis (19). A similar seasonal shift in growth form structure was observed for epilithic communities at the three sampling sites, where the number of erect group diatoms doubled (Hvar, Mljet) and tripled (Dubrovnik) in spring. Apart from erect forms, Dubrovnik and Mljet were characterised by adnate forms, while Hvar was characterised by tube-dwelling forms. The highest values of the Shannon-Wiener Diversity Index were recorded in autumn and ranged from 5.26 to 5.34. ANOSIM tests performed on species relative abundance data confirmed that the diatom communities differed significantly between the sampling sites, and that the differences were correlated with the presence of the two species of invasive macroalgae (Hvar – area of C. taxifolia; Mljet and Dubrovnik – areas of C. cylindracea). As revealed by SIMPER analyses, the group of taxa contributing the most to variance between diatom assemblages from sites of different invasive alga included Cocconeis scutellum var. scutellum, Rhopalodia pacifica, Navicula ramosissima, and Berkeleya rutilans. Although the spatial variation in communities may also reflect the effects of unmeasured environmental variables, the results suggest the possible influence of invasive seaweeds of the genus Caulerpa which may affect the habitat by competing with autochthonous algae. This study contributes to the knowledge of diatom diversity both at regional and at broader scales in these challenged environments.
