Long-term data series (1971–2015) of physical and biogeochemical parameters were analyzed in order to assess trends variability oceanographic conditions the northern Adriatic Sea (NAS), a mid-latitude shallow continental shelf strongly impacted by river discharges, human activities climate changes. Interpolation maps statistical models applied investigate seasonal spatial variability, as well decadal temperature, salinity, chlorophyll-a nutrients. This analysis shows that sea surface...
Abstract Spread of alien species (AS) is a serious threat to marine habitats and analysis principal descriptors their occurrence pivotal set reliable conservation strategies. In order assess the susceptibility biological invasions, dataset was gathered 3899 from 29 phyla, taken 93 sites located along Italian coast in period 2000–2012. total, 61 AS belonging 11 phyla have been recorded. Invertebrates were most represented (63%). Alien found all examined (EUNIS, level 2), although they showed...
Understanding the threats to global biodiversity and ecosystem services posed by human impacts on coastal marine environments requires establishment maintenance of ecological observatories that integrate biological, physical, geological biogeochemical aspects ecosystems. This is crucial provide scientists stakeholders with support knowledge necessary quantify environmental change its impact sustainable use seas coasts. In this paper, we explore potential for components International...
ABSTRACT Elemental stoichiometry and organic composition were investigated in an Adriatic strain of Skeletonema marinoi , cultured at 25 [low light (LL)] 250 [high (HL)] µ mol photon m −2 s −1 . Inorganic carbon acquisition, fixation allocation, silicic acid orthophosphate uptake also studied. The C : P ratio was below the Redfield ratio, especially LL. In HL cells, N quota halved, similar, silica lower, growth rate long‐term net primary productivity almost doubled, relative to LL cells....
Spatial and temporal variations of phytoplankton community structure were studied in the Gulf Venice (Northern Adriatic Sea) from February 1999 to December 2001 (INTERREG II, Italia–Slovenia project). Phytoplankton samples collected, with a monthly frequency, at 11 stations basin. Abundance, biomass, species composition considered. Synthetic descriptors used order evaluate main succession pattern cluster communities that typify different hydrological conditions. A decreasing gradient...
The Italian Fixed-Point Observatory Network (IFON) integrates well-established coastal and ocean infrastructures (buoys, platforms, moorings, mast etc.), most of them providing real-time multidisciplinary monitoring for a number marine atmospheric variables. Here, we describe the network characteristics then discuss an example its operation during cold spell winter 2012. One goals Flagship Project Ricerca Italiana per il mare (RITMARE) is to create common, validated IFON database able fulfil...
The Lagoon of Venice (LoV) and the Gulf (GoV), two adjacent coastal Long Term Ecological Research (LTER) sites in northern Adriatic Sea, represent a transitional/marine coupled ecosystem under influence regional local factors. In this study, these were sampled on four dates from April 2016 to February 2017 for environmental DNA relevant abiotic variables, aiming assess relative importance habitat heterogeneity connectivity structuring protist community. High Throughput Sequencing V4-18S rRNA...
By analysing a ten-year series (1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007) of data on hydrochemical properties, phytoplankton abundance and species composition in the Venice Lagoon, we identified i) average annual biomass cycle, mainly unimodal fairly well tuned with fluctuations temperature irradiance (ii) seasonal succession most important species, allowing us to construct "phytoplankton calendar".Phytoplankton was significantly lower second half period...
Two small high mountain lakes in the Alps were monitored 1984-2003 to follow their response changes human impact, such as deposition of atmospheric pollutants, fish stocking and climate change. The results compared occasional samplings performed 1940s, remains found sediment cores. When monitoring started, most acid-sensitive them, Lake Paione Superiore, was acidified, with evident effects its flora fauna: benthic diatoms assemblage shifted towards acidophilous species, zooplankton lost...
Abstract The changes in the plankton biomass structure relation to nutrient inputs were studied Gulf of Venice (Northern Adriatic Sea), an area characterized by a very marked trophic state variability. investigation was carried out at two stations, March, May and July 2005 2006, considering whole water column. size (from picoplankton mesozooplankton) both autotrophs heterotrophs analysed. Signals diluted waters more than 2006. In 2005, total almost double (87 ± 37 μg·C·l −1 ) that 2006 (44...
Taxonomic composition, biomass, primary production and growth rates of the phytoplankton community were studied in two stations NW Adriatic Sea on a seasonal basis, areas characterized by differing hydrological trophic conditions. The main differences between quantitative rather than qualitative, most species being common to both stations. effects nutrient concentrations plume spreading evident. Biomass significantly higher coastal station (S1), distribution water column was markedly...
We analyzed the phytoplankton abundance and community structure monthly over a 20-year period (1998–2017) at five stations in Venice lagoon (VL), one of sites belonging to Long-Term Ecological Research network Italy (LTER-Italy). focused on seasonal patterns, inter-annual variability long-term trends relation water quality. Diatoms numerically dominated (ca. 60% average), followed by nanoflagellates (37%), while coccolithophorids dinoflagellates contributed less than 2%. observed distinct...
The present work aims at evaluating the state of art phytoplankton production research in Italy. We a synthesis main results achieved three ecosystems where primary studies have been carried out most intensively: large subalpine lake (Lago Maggiore, LM), shallow marine ecosystem with strong fluvial influence (the Northern Adriatic Sea, NAS), and coastal area Southern Tyrrhenian Sea Gulf Naples, GoN). yearly values are around 150 g C m−2 yr−1 LM GoN; this ranges between 80 (offshore) (coast)...
Abstract The size distribution of the phytoplankton community has been analyzed on a monthly basis in Gulf Venice (NW Adriatic Sea), with aim to assess seasonal variation contribution autotrophic picoplankton (APP) total phytoplankton. investigation was carried out two stations characterized by different influences fluvial inputs. APP mainly made up Synechococcus , larger fraction (Utermöhl Fraction Phytoplankton, UFP: µm as maximum linear dimension) diatoms and nanoflagellates. average...
High environmental variability is a feature of transitional water ecosystems, which also affects temporal and spatial patterns phytoplankton. The Lagoon Venice characterised by wide range conditions, high phytoplankton species diversity abundance variability. Here we focus on morphological traits specifically, for the first time in waters, geometric shape. Our hypothesis that despite taxonomic diversity, prevalent features lagoon (shallow, permanently nutrient-enriched, turbulent...
Abstract. In this paper we describe a 50-year (1965–2015) ecological database containing data collected in the northern Adriatic Sea (NAS) at one of 25 research parent sites belonging to Italian Long Term Ecological Research Network (LTER-Italy, http://www.lteritalia.it, last access: February 2020). LTER-Italy is formal member International (https://www.ilter.network, 2020) and European (http://www.lter-europe.net/, LTER networks. The NAS undergoing process, led by different institutions...
Abstract This paper presents a winter carbon budget for the northern Adriatic Sea, obtained through direct measurements during two multidisciplinary cruises and literature data. A box model approach was adopted to integrate estimates of stocks fluxes species over total area. The oligotrophy at basin scale start primary productivity well before onset spring stratification were observed. In winter, system underwent complete reset, as mixing water masses erased any signal previous hypoxia or...
