How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

The Italian spined loach (Cobitis bilineata) is an elongated, small sized (<12 cm) spined loach native to Northern Italy, Slovenia and Croatia. As for loaches in general, little is known about their individual movements in nature. Passive integrated transponders (PIT-tags) are small (typically 7–32 mm), relatively cheap, and allow tracking of indiv...
We developed and compared two analytical methods for determination of MeHg in freshwater biota and sediments, by: I) simplified static headspace GC-MS using internal standard (IS) isotope dilution quantification, after microwave acid digestion and aqueous phase NaBEt4 ethylation; II) Automated Mercury Analyzer, after double toluene extraction follo...
Lake tributaries collect contaminants from the watershed, which may accumulate in lake sediments over time and may be removed through the outlets. DDx, PCB, PAH, PBDE, and trace element (Hg, As, Cd, Ni, Cu, Pb) contamination was analyzed over 2001–2018 period in sediments of the 5 main tributaries and of the outlet of Lake Maggiore (Northern Italy)...
River sediments generally act as a sink for trace elements but, when resuspended, they contribute to long-term downstream transport of contamination, which may finally reach the marine environment. This study analyzed these processes in a complex aquatic system that includes a contaminated tributary, the Lambro River (Northern Italy) and its recipi...
Freshwater fish communities are impacted by multiple pressures, determining loss of functional diversity and redundancy. Our aim was to disentangle the roles and relevancies of different pressures in shaping fish communities in small streams of the Po plain (North Italy). Long term trend (1998–2018) of functional diversity of 31 fish communities wa...
Oviparous mothers transfer to the eggs components that have both independent and combined effects on offspring phenotype. Functional interactions between egg components, such as antioxidant and hormones, lead to expect that a change in the concentration of one component has effects on offspring traits that depend on the concentration of other inter...
Monitoring of emerging contaminants and dangerous substances in Lake Maggiore ecosystem
RIBES (River flow regulation, fish BEhaviour and Status) European Training Network (ETN) will train 15 ESRs in the interdisciplinary field of Ecohydraulics to find innovative solutions for freshwater fish protection and river continuity restoration in anthropogenically altered rivers.
