Ecosystem vulnerability to alien and invasive species: a case study on marine habitats along the Italian coast
To assess the susceptibility of marine habitats to biological invasions, a dataset was gathered of the occurrence of 3899 species from 29 phyla, taken from 93 marine sites located along the Italian coast in the period 2000-2012.
Ecological assessment of anthropogenic impact in marine ecosystems: The case of Bagnoli Bay.
It is found that contamination differentially affects the communities' composition in the bay, with prokaryotes influenced only by depth, and benthos not following the environmental gradient at all, and indices based on interspecific interactions are better indicators of environmental gradients than those defined based on species composition exclusively.
Biomarkers employment in planktonic copepods for early management and conservation of aquatic ecosystems: The case of the ‘Capo Peloro’ lakes (southern Italy)
The data indicate that for the two lakes of Capo Peloro there is contamination by pesticides, carbamates and polycyclic and polyhalogenated aromatic hydrocarbons at the end of the summer season, and only affects the species of the low trophic levels.
Environmental and Benthic Community Patterns of the Shallow Hydrothermal Area of Secca Delle Fumose (Baia, Naples, Italy)
The occurrence of hydrothermal vent ecosystems at Secca delle Fumose, Pozzuoli Bay (Gulf of Naples), represented an opportunity to study the benthic assemblages under the thermal stress of
Diet and trophic ecology of the lanternfish Electrona risso (Cocco 1829) in the Strait of Messina (central Mediterranean Sea) and potential resource utilization from the Deep Scattering Layer (DSL)
The results indicate that E. risso is a specialist predator, which feeds mainly on the small mesopelagic fish Cyclothone braueri and in minor proportion on zooplankton, with a prevalence of copepods.
Soft-bottom macrofaunal assemblages in the Gulf of Salerno, Tyrrhenian Sea, Italy, an area affected by the invasion of the seaweed Caulerpa racemosa var. cylindracea
Although overall local diversity did not change in the study area, the composition of the macrofaunal assemblages in 2006–2007 differed from that in 1981, and the most conspicuous changes were a decline in infaunal bivalve molluscs and an increase of mobile epibenthic forms; these may be linked to the influence of C. racemosa on sediment properties.
The Otranto Channel (South Adriatic Sea), a hot-spot area of plankton biodiversity: pelagic polychaetes
The presence of several non-determined polychaete larvae in the pelagic waters at 800–1100 m depths suggests the importance of the role of Levantine waters as main actual and potential carrier of species in the area, though a relevant contribution comes also from North Adriatic dense waters through deep spilling and cascading in the Southern Adriatics pit.
Consumption of mesopelagic prey in the Strait of Messina, an upwelling area of the central Mediterranean Sea: feeding behaviour of the blue jack mackerel Trachurus picturatus (Bowdich, 1825)
Abstract This study describes for the first time the feeding behaviour and mesopelagic food consumption of adult Trachurus picturatus in the Strait of Messina (central Mediterranean Sea), where the
Composition, abundance and distribution of holoplanktonic polychaetes within the Strait of Magellan (southern America) in austral summer
Both of the most abundant species were concentrated in the deepest layers sampled (below 100 m) throughout day and night hours without showing any specific migratory behavior.
MicroNESS: an innovative opening–closing multinet for under pack-ice zooplankton sampling
The comparison among the ice-associated copepod communities collected by MicroNESS and those of three traditional sampling techniques showed that MicroNESS can provide useful insights about changes in composition, biomass and particle size structure of this key plankton component, especially on a short timescale during ice melting.
