Recent Trends Towards Oligotrophication of the Northern Adriatic: Evidence from Chlorophyll a Time Series
The results of the updated and quality-checked data base of field observations on chlorophyll a (Chl a) collected in the period 1970–2007 in the Northern Adriatic Sea are presented. From the last…

This work analyzes and reviews long-term records of Mediterranean ecological and hydro-climate variables and finds that all point to a synchronous change in the late 1980s that encompassed atmospheric, hydrological, and ecological systems, for which it can be considered a regime shift.
Climate Change and the Potential Spreading of Marine Mucilage and Microbial Pathogens in the Mediterranean Sea
It is concluded that the spreading of mucilage in the Mediterranean Sea is linked to climate-driven sea surface warming and the mucilage can act as a controlling factor of microbial diversity across wide oceanic regions and could have the potential to acts as a carrier of specific microorganisms, thereby increasing the spread of pathogenic bacteria.

It is concluded that marine microbial components, and particularly prokaryotes, are highly effective for detecting the effects of anthropogenic pressures on marine environments and for assessing changes in the environmental health status and recommended the inclusion of these components in future implementations of the MSFD.
Significance of bacteria in the mucilage phenomenon in the northern Adriatic Sea.
This paper develops the thesis that bacteria play major roles in mucilage formation and integrates these roles of bacteria into a conceptual model which emphasizes microscale interactions of microbes within a seawater gel matrix as the basis for a mechanistic understanding of the accumulation of long-lived polysaccharide to form mucilage.

Besides the high year-to-year variations in abundances and taxonomical composition, plankton communities only showed a clear seasonal succession during 2001, when since April a grazing food web developed and was able to control large sized phytoplankton increase.
Imbalance between phytoplankton production and bacterial carbon demand in relation to mucilage formation in the Northern Adriatic Sea.

There were indications of an uncoupling between phytoplankton photosynthesis and growth and of a shift from an autotrophic to a heterotrophic metabolism, especially during the spring and summer period when mucilage might occur.
Integrated approach to sediment pollution: a case study in the Gulf of Trieste.

The aim of this study was to assess the sediment quality near the outlet of the main wastewater pipeline of the city, and the resulting composition of species, replacements, eliminations, diversity or abundance changes, can indicate the recent history of events affecting the area.
Planktonic prokaryote and protist communities in a submarine canyon system in the Ligurian Sea (NW Mediterranean)
Abstract Submarine canyons are large geomorphological features that incise continental margins and act as highly dynamic conduits of sediments from shallow to the deep-sea regions. They are often…
Biodiversity of settled material in a sediment trap in the Gulf of Trieste (northern Adriatic Sea)
Phytoplankton succession and sinking rates were studied from January to December 2003 at a coastal station in the Gulf of Trieste (northern Adriatic Sea), 200 m offshore, in a relatively undisturbed…
