Distribution and ecological relevance of fine sediments in organic-enriched lagoons: the case study of the Cabras lagoon (Sardinia, Italy).
Monitoring programs in organic-enriched coastal lagoons should primarily investigate and consider the cohesive fraction of sediments in order to allow a better assessment of benthic-sediment relationships and ecological quality of the system. Expand
Relationships Between Chemical Characteristics of Sediments and Macrofaunal Communities in the Cabras Lagoon (Western Mediterranean, Italy)
The Cabras lagoon is a large and shallow transitional system which periodically suffers from dystrophic events leading to massive losses of its biological resources. Excessive organic matter (OM) andExpand
Sediment characteristics and macrofauna distribution along a human-modified inlet in the Gulf of Oristano (Sardinia, Italy).
It is suggested that the removal of artificial structures along the inlet would favour water renewal in the Cabras lagoon, but would also increase the outflow of organic C-bonding fine particles into the gulf with serious consequences for Posidonia oceanica and Cymodocea nodosa seagrass meadows.

Variance estimate and taxonomic resolution: an analysis of macrobenthic spatial patterns at different scales in a Western Mediterranean coastal lagoon.
In future studies aimed at assessing changes in the lagoon, resources derived from the cost reductions achieved using family level could be employed to plan more frequent surveys and/or to adopt complex spatial sampling designs with a high number of replicates. Expand
Comparative analysis of macrofaunal species richness and composition in Posidonia oceanica, Cymodocea nodosa and leaf litter beds
The results confirmed the facilitative role of living seagrasses, in particular P. oceanica, as related to their structural complexity, for numerous species from different substrates (e.g., hard bottom species) and showed that leaf litter beds act as a particular environment where sediment instability, leaf breakdown, and organic matter enrichment and decomposition strongly influence animal distribution.

Macrofaunal community structure and distribution in a muddy coastal lagoon
Macrofaunal communities and specific bulk properties of organically enriched sediments were investigated in the coastal lagoon of Cabras (Sardinia, western Mediterranean) on a grid of twenty-nineExpand
Aromatase expression in cultured fetal sheep astrocytes after nitrosative/oxidative damage
Stressed astrocytes showed signs of deterioration, were reduced in number, and appeared round with few short processes; the cell death rate was ∼30%. Expand
Microcystins Presence in Mussels (M. galloprovincialis) and Water of Two Productive Mediterranean's Lagoons (Sardinia, Italy)
Monitoring of microcystins in water and mussels of two Sardinia lagoons in spring and summer found a constant trend in the concentration of MCs during the considered months, while there was a MCs peak in July. Expand
Reorganization of actin cytoskeleton in L929 cells infected with Coxiella burnetii strains isolated from placenta and foetal brain of sheep (Sardinia, Italy).
Investigation of the ability of 2 Coxiella strains isolated from ovine aborted samples to induce reorganization of the actin cytoskeleton in mouse fibroblast cells indicates that similarly to the virulent reference strain, strains of C. burnetii isolated from foetal brain induced morphological changes - modification in F‑actin distribution and in the localization of bacteria.

Disentangling heterogeneity and commonalities in nanotidal Mediterranean lagoons through environmental features and macrozoobenthic assemblages
Abstract A comprehensive set of physiographic and environmental features, anthropogenic pressures, as well as the soft-bottom macrozoobenthic assemblages were analyzed in seven nanotidal lagoonsExpand
