Natural patterns and anthropogenic disturbance in north Adriatic marine benthic assemblages: descriptive and methodological studies
… the methodological approaches to the study of biological variability in soft bottom habitats and in increasing the knowledge of the effect that different process (both natural and anthropogenic) could have on the benthic communities of a large area in the North Adriatic Sea. Beta diversity is a …

Effects of habitat characteristics on cryptic fish assemblages
… the abundance of fishes on temperate reefs. Biotic interactions play a major role in determining the distribution and abundance of species. The significance of these forces in affecting the abundance of fishes may hinge on the presence of organisms that either create or alter habitat. On …

Il contributo di sorgenti locali sull'impatto ambientale da Diossine e Furani
Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are ubiquitous contaminants, mainly released into the environment during combustion processes (point sources), but also from other sources (traffic, waste incinerators, uncontrolled combustion). This Ph.D. thesis is …

Effects of anthropogenic and natural disturbance on sedimentary organic matter quantity, nutritional quality and degradation in river, lagoon, and coastal marine ecosystems
… role in regulating habitats’ structure and biodiversity. Aquatic ecosystems, especially lagoons and marine coastal areas, appear to be more sensitive to anthropogenic and natural disturbances than terrestrial ones, whose ecological consequences are more tangible. Changes in the trophic …

Drivers and effects of plastic contamination in aquatic ecosystems
… P. elephas and N. norvegicus could be valuable bioindicators and charismatic species that could represent excellent flagship species for raising awareness toward the global issue of plastic in the marine environment (Chapter 3). Finally, moving to freshwater environments, the last chapter is a …
