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 …

BIO-ECOLOGICAL AND ANATOMICAL ASPECTS OF THE EUROPEAN EEL ANGUILLA ANGUILLA (L. 1758)
… decline since the 1970s. Starting from 2007, has been protected by the European Council Regulation 1100/2007, and successively classified as Critically Endangered (CR). Although conspicuous efforts have been conducted, to implement knowledge and identify possible solutions to preserve the …

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 …

BETWEEN LIGHT AND DARKNESS: THE ROUND-TRIP OF SURFACE AND SUBTERRANEAN ANIMALS
Caves are extreme environments, this definition is mostly due to the absence of sunlight that limits the abundance of trophic resources in this environment. The animals that live there, in order to exploit of this ecosystem, must show particular adaptations such as an extremely reduced metabolism, …

CHROMOSOME-LEVEL DE NOVO GENOME ASSEMBLIES OF AVIAN SPECIES AND THEIR RELEVANCE FOR COMPARATIVE GENOMICS, PANGENOMICS, POPULATION GENOMICS AND SPECIES CONSERVATION.
… changes, leading to a progressive collapse of biodiversity. The establishment of conservation initiatives is now more crucial than ever and the genetic management of threatened species is currently gaining critical significance. Previous genetic studies have been limited by the lack of complete …

The influence of redox dynamics on nitrogen cycling and nitrous oxide emissions from soils
… time scale of water dynamic was faster than the biological scale of trace gas emissions. Finally, the relationship of nitrous oxide versus water content was reproduced by using a lumped model which include oxygen dynamic. Preliminary results suggest that by accounting for oxygen dynamic, it is …
