Article
Full-text available
Coastal zones are exposed to various anthropogenic impacts, such as different types of wastewater pollution, e.g., treated wastewater discharges, leakage from sewage systems, and agricultural and urban runoff. These various inputs can introduce allochthonous organic matter and microbes, including pathogens, into the coastal marine environment. The...
Article
Full-text available
Jellyfish blooms can represent a significant but largely overlooked source of organic matter (OM), in particular at the local and regional scale. We provide an overview of the current state of knowledge on the bloom‐forming jellyfish as sink and source of OM for microorganisms. In particularly, we compare the composition, concentration, and release...
Chapter
Chesapeake Bay (CB) and the northern Adriatic Sea (NAS) exhibit contrasting patterns in trophic status and thereby offer contrasting case studies in microbial ecology. In the surface mixed layer in both systems, the abundance and productivity of cyanobacteria and of heterotrophic bacteria exhibit summer maxima and winter minima. Available evidence...
Article
Full-text available
When jellyfish blooms decay, sinking jellyfish detrital organic matter (jelly-OM), rich in proteins and characterized by a low C:N ratio, becomes a significant source of OM for marine microorganisms. Yet, the key players and the process of microbial jelly-OM degradation and the consequences for marine ecosystems remain unclear. We simulated the sce...
Article
Full-text available
Despite accumulating evidence of the importance of the jellyfish-associated microbiome to jellyfish, its potential relevance to blue biotechnology has only recently been recognized. In this review, we emphasize the biotechnological potential of host–microorganism systems and focus on gelatinous zooplankton as a host for the microbiome with biotechn...
Article
Full-text available
Jellyfish are a prominent component of the plankton community. They frequently form conspicuous blooms which may interfere with different human enterprises. Among the aspects that remain understudied are jellyfish associations with microorganisms having potentially important implications for organic matter cycling. To the best of our knowledge, thi...
Article
At present there is no consistent approach for the definition of Good Environmental Status (GES) and targets in the Mediterranean Sea, especially for Biodiversity Descriptors, according to the Article 12 of the Marine Strategy Framework Directive (MSFD). The use of plankton indicators in the Mediterranean Sea refers mostly to pelagic habitats in co...
Preprint
Full-text available
This study is the first to investigate bacterial community associated with live medusa Aurelia sp. in the Gulf of Trieste (northern Adriatic Sea) using both culture independent and culture-based methods. We have analysed bacterial community composition of different body parts of medusa: exumbrella surface, oral arms ('outer' body parts) and of gast...
Article
Ports are subject to a variety of anthropogenic impacts, and there is mounting evidence of faecal contamination through several routes. Yet, little is known about pollution in ports by faecal indicator bacteria (FIB). FIB spatio-temporal dynamics were assessed in 12 ports of the Adriatic Sea, a semi-enclosed basin under strong anthropogenic pressur...
Article
Ballast water discharges may cause negative impacts to aquatic ecosystems, human health and economic activities by the introduction of potentially harmful species. Fifty untreated ballast water tanks, ten in each port, were sampled in four Adriatic Italian ports and one Slovenian port. Salinity, temperature and fluorescence were measured on board....
Article
This proof of concept study presents a Bayesian Network (BN) approach that integrates relevant biological and physical-chemical variables across spatial (two water layers) and temporal scales to identify the main contributing microbial mechanisms regulating POC accumulation in the northern Adriatic Sea. Three scenario tests (diatom, nanoflagellate...
Chapter
Full-text available
A comprehensive review of ballast water sampling and analyses methods for CME indicative analyses and detailed test was conducted. Missing BWS sampling and analyses tools were identified and bought to provide each participating county with an indicative and detailed test for in-tank and at-discharge sampling. BWS and analyses methods were be tested...
Article
Full-text available
Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world’s oceans. It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a singl...
Article
Full-text available
Consumer wine preferences are changing rapidly towards exotic flavours and tastes. In this work, we tested five non-conventional yeast strains for their potential to improve Ribolla Gialla wine quality. These strains were previously selected from numerous yeasts interesting as food production candidates. Sequential fermentation of Ribolla Gialla gr...
Article
Jellyfish play a key role in many pelagic ecosystems, especially in areas of extensive bloom events. In order to understand their role in pelagic food webs and in biogeochemical cycling, the energy stored and the trophic level occupied by jellyfish need to be quantified. To date, the common protocols applied for quantifying jellyfish biomass and an...
Article
The potential link between the microbial dynamics and the environmental parameters was investigated in a semi-enclosed and highly dynamic coastal system (Gulf of Trieste, northern Adriatic Sea, NE Mediterranean Sea). Our comprehensive 2 year time - series study showed that despite the shallowness of this area there was a significant difference betw...
Article
Full-text available
To obtain insights into the coupling between community composition, diversity and community function, bacterioplankton assemblages from the Gulf of Trieste (Northern Adriatic Sea) were exposed to increasing environmental stress throughout 2 wk in continuous seawater cultures to construct communities differing in composition and diversity. The assem...
Article
A series of relatively simple incubation experiments to assess and evaluate microbial mercury (Hg) transformations in water column and sediments were performed monthly or bimonthly in a period from March 2011 to December 2011. Sampling campaigns were performed at station F in the southeastern part of Gulf of Trieste, northern Adriatic Sea. Gulf of...

The epiplankton community was investigated during Meduza cruises along south -north and offshore – inshore transects in the middle and southern Adriatic in spring 2002. The diel and vertical distribution of heterotrophic bacteria, phytoplankton pigment composition, micro-and meso-zooplankton were assessed. At most stations we observed a thermocline...
Article
Full-text available
Jellyfish blooms have increased in coastal areas around the world and the outbreaks have become longer and more frequent over the past few decades. The Mediterranean Sea is among the heavily affected regions and the common bloom-forming taxa are scyphozoans Aurelia aurita s.l., Pelagia noctiluca, and Rhizostoma pulmo. Jellyfish have few natural pre...

Article
Deoxyribonucleoside kinases (dNKs) are essential in the mammalian cell but their 'importance' in bacteria, especially aquatic ones, is less clear. We studied two aquatic bacteria, Gram-negative Flavobacterium psychrophilum JIP02/86 and Polaribacter sp. MED152, for their ability to salvage deoxyribonucleosides (dNs). Both had a Gram-positive-type th...
Article
Full-text available
The decomposition of jellyfish after major bloom events results in the release of large amounts of nutrients, which can significantly alter nutrient and oxygen dynamics in the surrounding environment. The response of the ambient bacterial community to decomposing jellyfish biomass was evaluated in two marine ecosystems, the Gulf of Trieste (norther...

Marine biota and the ecosystems of coastal areas are exposed to a combination of multiple drivers that operate over a broad range of spatial and temporal scales. Moreover, anthropogenic stressors drive changes that are embedded into natural variability. The long-term goal of the research programme is to contribute to the understanding of the structural and functional characteristics of coastal and semi-enclosed seas which are characterized by complex dynamics due to different stressors.
